may be issued under the Plan is 2,500,000 Shares. The Shares may be authorized, but unissued, or reacquired Common Stock. 
 (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). With
respect to Stock Appreciation Rights, only Shares actually 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 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
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
withholding tax and exercise price associated with 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 reduce the number of
Shares available for issuance under the Plan. Notwithstanding the foregoing and, 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). 

4. Administration of the Plan. 

(a) Procedure. 
 (i)
Multiple Administrative Bodies. The Plan may be administered by different Committees with respect to different groups of Service Providers. 

(ii) Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Options 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 or more “outside directors” within the meaning of
Section 162(m) of the Code. 

  
 6 








 (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. 
 (v)
Delegation of Authority for Day-to-Day Administration. Except to the extent prohibited by Applicable Law, the Administrator may delegate to one or more
individuals the day-to-day administration of the Plan and any of the functions assigned to it in this Plan. Such delegation may be revoked at any time. 

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

(iii) to determine whether and to what extent Awards or any combination thereof, are granted hereunder; 

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

(v) to approve forms of agreement for use under the Plan; 

(vi) 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 Options or Stock Appreciation Rights may be exercised or other Awards vest (which may be based on performance criteria), any vesting acceleration or waiver of
forfeiture or repurchase restrictions, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator, in its sole discretion, will determine; 

(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 qualifying for preferred tax treatment under foreign tax laws; 

  
 7 








 (ix) to modify or amend each Award (subject to Section 18(c) of the Plan), including
the discretionary authority to extend the post-termination exercisability period of Awards longer than is otherwise provided for in the Plan. Notwithstanding the previous sentence, the Administrator may not modify or amend an Option or Stock
Appreciation Right to reduce the exercise price of such Option or Stock Appreciation Right after it has been granted (except for adjustments made pursuant to Section 13) nor may the Administrator cancel any outstanding Option or Stock
Appreciation Right and replace it with a new Option or Stock Appreciation Right with a lower exercise price, unless, in either case, such action is approved by the Company’s stockholders; 

(x) 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; 
 (xi) 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; 
 (xii) to determine
whether Awards will be settled in Shares, cash or in any combination thereof; 
 (xiii) to establish a program whereby Service Providers
designated by the Administrator can reduce compensation otherwise payable in cash in exchange for Awards under the Plan; 
 (xiv) to
implement an Award Transfer Program; 
 (xv) to impose such restrictions, conditions or limitations as it determines appropriate as to the
timing and manner of any resales by a Participant or other subsequent transfers by the Participant of any Shares issued as a result of or under an Award, including without limitation, (A) restrictions under an insider trading policy, and
(B) restrictions as to the use of a specified brokerage firm for such resales or other transfers; and 
 (xvi) 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 and
Performance Shares may be granted to Service Providers. Incentive Stock Options may be granted only to Employees of the Company or any Parent or Subsidiary of the Company. A Service Provider who has been granted an Award may, if otherwise eligible,
be granted additional Awards. 

  
 8 








 6. Stock Options. 

(a) Limitations. 
 (i)
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, 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. 
 (ii) The following limitations will apply to grants of Options: 

A. No Service Provider will be granted, in any Fiscal Year, Options to purchase more than 5,000,000 Shares. 

B. In connection with his or her initial service as an Employee, a Service Provider may be granted Options to purchase up to
an additional 5,000,000 Shares, which will not count against the limit set forth in Section 6(a)(ii)(A) above. 
 C.
The foregoing limitations will be adjusted proportionately in connection with any change in the Company’s capitalization as described in Section 13. 

D. If an Option is cancelled in the same Fiscal Year in which it was granted (other than in connection with a transaction
described in Section 13), the cancelled Option will be counted against the limits set forth in subsections (A) and (B) above. For this purpose, if the exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option. 
 (b) Term of Option. The Administrator will determine the term of each
Option in its sole discretion; provided, however, that 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. 

  
 9 








 (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: 
 A. 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 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 100% of the Fair Market Value per Share on the date of grant. 
 B. In the case of a Nonstatutory Stock Option,
the per Share exercise price 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. 

C. Notwithstanding the foregoing, 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 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 an 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. 

(ii) Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the
Participant’s death, disability or Retirement, 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 

  
 10 








 
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 six (6) 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 six (6) 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. 

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, provided that during any Fiscal Year, no Participant will be granted Stock Appreciation Rights covering more
than 5,000,000 Shares. Notwithstanding the foregoing limitation, in connection with a Participant’s initial service as an Employee, an Employee may be granted Stock Appreciation Rights covering up to an additional 5,000,000 Shares. 

  
 11 








 (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 one hundred percent (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. 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. 
 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. Notwithstanding the foregoing, during any Fiscal Year no Participant will receive more than an aggregate of
1,500,000 Shares of Restricted Stock; provided, however, that in connection with a Participant’s initial service as an Employee, an Employee may be granted an aggregate of up to an additional 1,500,000 Shares of Restricted Stock. 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. 

  
 12 








 (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. 

(i) General. 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 restrictions will lapse at a rate determined by the Administrator. After the grant of Restricted Stock, the Administrator,
in its sole discretion, may reduce or waive any restrictions for such Restricted Stock. 
 (ii) Section 162(m) Performance
Restrictions. For purposes of qualifying Awards of Restricted Stock as “performance-based compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of
Performance Goals, which shall be set by the Administrator on or before the Determination Date. In this connection, the Administrator shall follow any procedures determined by it from time to time to be necessary or appropriate to ensure
qualification of the Stock Purchase Right under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 (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 

  
 13 








 
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. Notwithstanding the anything to the contrary in this subsection (a), during any fiscal year
of the Company, no Participant will receive more than an aggregate of 1,500,000 Restricted Stock Units; provided, however, that in connection with a Participant’s initial service as an Employee, an Employee may be granted an aggregate of up to
an additional 1,500,000 Restricted Stock Units. 
 (b) Vesting Criteria and Other Terms. 

(i) General. 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 upon or in connection with a Change in Control or upon or in connection with a Participant’s termination of service, including, without limitation, due to death or disability. 

(ii) Section 162(m) Performance Restrictions. For purposes of qualifying Restricted Stock Units as “performance-based
compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may set restrictions based upon the achievement of Performance Goals, which shall be set by the Administrator on or before the Determination Date. In this
connection, the Administrator shall follow any procedures determined by it from time to time to be necessary or appropriate to ensure qualification of the Stock Purchase Right under Section 162(m) of the Code (e.g., in determining the Performance
Goals). 
 (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. 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) 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 

  
 14 








 
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 provided that
during any Fiscal Year no Participant will receive more than 1,500,000 Performance Shares or Performance Units. Notwithstanding the foregoing limitation, in connection with a Participant’s initial service as an Employee, an Employee may be
granted up to an additional 1,500,000 Performance Shares or Performance Units. 
 (b) Value of Performance Units/Shares. Each
Performance Unit will be a bookkeeping entry representing an amount equal to the Fair Market Value of one Share and will represent an unfunded and unsecured obligation of the Company. 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. 

(i) General. 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 Participant. 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. 

(ii) Section 162(m) Performance Objectives. For purposes of qualifying grants of Performance Units/Shares as “performance-based
compensation” under Section 162(m) of the Code, the Administrator, in its discretion, may determine that the performance objectives applicable to Performance Units/Shares will be based on the achievement of Performance Goals. The Administrator
will set the Performance Goals on or before the Determination Date. In granting Performance Units/Shares which are intended to qualify under Section 162(m) of the Code, the Administrator will follow any procedures determined by it from time to time
to be necessary or appropriate to ensure qualification of the Performance Units/Shares under Section 162(m) of the Code (e.g., in determining the Performance Goals). 

(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. 

(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. 

  
 15 








 11. Leaves of Absence. The Administrator shall determine the effect on an Award of the
authorized leave of absence or other change in the employment or other status of a Participant. 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 three (3) 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. 
 12. Non-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 recipient, only by the recipient. 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, may (in its sole discretion) 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 Sections 3, 6, 7, 8, 9 and 10. 
 (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. The Administrator in its discretion may provide for a Participant to have the right to
exercise his or her Award, to the extent applicable, until ten (10) days prior to such transaction as to all of the Awarded Stock covered thereby, including Shares as to which the Award would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option or forfeiture rights applicable to any Award will lapse 100%, and that any Award vesting will accelerate 100%, provided the proposed dissolution or liquidation takes place at the time and
in the manner contemplated. To the extent it has not been previously exercised or vested, 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 each Award be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator will not be required to treat all Awards
similarly in the transaction. 

  
 16 








 In the event that the successor corporation does not assume or substitute for the Award, unless
the Administrator provides otherwise, 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 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. 

With respect to Awards granted to non-employee Directors that are assumed or substituted for, if on
the date of or following such assumption or substitution the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant, 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 subject thereto, 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.

 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 Restricted Stock Unit, 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 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 Share or Performance Unit, for each Share subject to such Award (or in the case of Restricted Stock
Units and Performance Units, the number of implied Shares determined by dividing the value of the Restricted Stock Units or Performance Units, as applicable, by the per share consideration received 

  
 17 








 
by holders of Common Stock in the Change in Control), 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 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). 

(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 (without limitation) by (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair Market
Value equal to the 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, or (v) retaining from salary or other amounts
payable to the Participant in cash having a sufficient value to satisfy 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 an Award. The date of grant of an Award will be, for all purposes,
the date on which the Administrator makes the determination to grant such Award, or such other date as is determined by the Administrator. Notice of the grant determination will be given to each Service Provider to whom an Award is so granted within
a reasonable time after the date of such grant. 

  
 18 








 17. Term of Plan. Subject to Section 23 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. 

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 the Award or the issuance
and delivery of such Shares (or with respect to Performance Units, the cash equivalent thereof) 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 or receipt of an Award, the Company may require the person exercising or
receiving such Award to represent and warrant at the time of any such exercise or receipt 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. Severability. Notwithstanding any contrary provision of the Plan or an Award
to the contrary, if any one or more of the provisions (or any part thereof) of this Plan or the Awards will be held invalid, illegal or unenforceable in any respect, such provision will be modified so as to make it valid, legal and enforceable, and
the validity, legality and enforceability of the remaining provisions (or any part thereof) of the Plan or Award, as applicable, will not in any way be affected or impaired thereby. 

  
 19 








 21. Liability of Company. 

(a) 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. 
 (b) Grants Exceeding Allotted Shares. If the Shares covered by an Award exceed, as of the
date of grant, the number of Shares which may be issued under the Plan without additional stockholder approval, such Award will be void with respect to such excess Shares, unless stockholder approval of an amendment sufficiently increasing the
number of Shares subject to the Plan is timely obtained in accordance with Section 18(b) of the Plan. 
 22. Reservation of
Shares. 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.  

23. 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. 

24. Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the
laws of the Commonwealth of Massachusetts, excluding choice-of-law principles of the law of such state that would require the application of the laws of a jurisdiction
other than such state.
