 3. Stock Subject to the Plan. 
 (a) Stock Subject to the Plan. Subject to the provisions of Section 14 of the Plan, the maximum aggregate number of Shares
that may be issued under the Plan is 10,369,190 (prior to any adjustment to reflect any stock split which may be completed by the Company prior to the initial registration by the Company of its Shares under Section 12 of the Exchange Act),
which includes (i) a new number of Shares reserved for issuance, plus (ii) the number of Shares which have been reserved but not issued under the Company’s 1998 Stock Option Plan (the “1998 Plan”) as of the Registration
Date, up to a maximum of 326,273 Shares (prior to any adjustment to reflect any stock split which may be completed by the Company prior to the initial registration by the Company of its Shares under Section 12 of the Exchange Act), and
(iii) any Shares which may be returned to the 1998 Plan as a result of termination of options or repurchase of Shares issued under the 1998 Plan, up to a maximum of 1,919,190 Shares (prior to any adjustment to reflect any stock split which may
be completed by the Company prior to the initial registration by the Company of its Shares under Section 12 of the Exchange Act). The Shares may be authorized, but unissued, or reacquired Common Stock. 
 (b) Automatic Share Reserve Increase. The number of Shares available for issuance under the Plan shall be increased on the first
day of each Fiscal Year beginning with the 2007 Fiscal Year, in an amount equal to the lesser of (A) 630,000 Shares, (B) 3.5% of the outstanding Shares on the last day of the immediately preceding Fiscal Year or (C) such lesser number
of Shares determined by the Board. 
 (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, the
unpurchased Shares (or for Awards other than Options or SARs 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 SARs, only
Shares actually issued pursuant to an SAR will cease to be available under the Plan; all remaining Shares under SARs 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 issued pursuant to Awards of Restricted Stock, Performance Units or
Performance Shares 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 minimum statutory withholding
obligations related to an Award will become available for future grant or sale 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 shall equal the aggregate Share number stated in Section 3(a), plus, an additional number of Shares equal to that portion of each automatic increase specified in Section 3(b) that does not exceed 630,000 Shares.

 (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 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. 
 (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: 
 (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 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 determine the terms and conditions of any, and to institute any Exchange Program; 
 (vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 
  

 -6- 








 (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; 
 (ix) to modify or amend each Award (subject to Section 19(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Awards; 
 (x) to allow Participants to satisfy withholding tax obligations in such manner as prescribed in Section 15; 
 (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 would otherwise be due to such Participant under an Award 
 (xiii) 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, SARs, Performance Units and Performance Shares 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,
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. 
 (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. 
  

 -7- 








 (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 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. 
 c) Notwithstanding the foregoing, Incentive
Stock 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.

 (2) In the case of a Nonstatutory Stock Option, the per Share exercise price will be no less than 100% of the Fair Market
Value per Share on the date of grant. 
 (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) other Shares, provided Shares acquired directly or indirectly from the Company, (A) have been owned by the Participant and not subject to substantial risk of forfeiture for more than six months on the date of surrender, and
(B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option will be exercised; (4) consideration received by the Company under a broker-assisted cashless exercise
program; (5) any combination of the foregoing methods of payment; or (6) such other consideration and method of payment for the issuance of Shares 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 

  

 -8- 








 
is exercised (together with an 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 Optioned Stock, 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 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 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 

  

 -9- 








 
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.

 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, 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 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.

 (b) Vesting Criteria and Other Terms. The Administrator shall 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. 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. 
 (c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant shall be entitled to receive a payout as specified in the Restricted Stock Unit 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 shall be made as soon as practicable after the date(s) set
forth in the Restricted Stock Unit Award Agreement. The Administrator may only settle earned Restricted Stock Units in Shares. 
 (e) Cancellation. On the date set forth in the Restricted Stock Unit Award Agreement, all unearned Restricted Stock Units shall be forfeited to the Company.

Provider. 
 (c) Exercise Price and Other Terms. The per share exercise price for the Shares to be issued pursuant to
exercise of an SAR shall be determined by the Administrator and shall be no less than 100% of the Fair Market Value per share on the date of grant. Otherwise, subject to Section 6(a) of the Plan, the Administrator, subject to the provisions of
the Plan, shall have complete discretion to determine the terms and conditions of SARs granted under the Plan; provided, however, that no SAR may have a term of more than ten (10) years from the date of grant. 
 (d) SAR Agreement. Each SAR grant will be evidenced by an Award Agreement that will specify the exercise price, the term of the
SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 
  

 -11- 








 (e) Expiration of SARs. An SAR 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 SARs. 
 (f) Payment of SAR Amount. Upon exercise of an SAR, 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 SAR is exercised. 
 The payment upon SAR exercise may only be in Shares of equivalent value (rounded down to the nearest whole Share). 
 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, or individual goals, 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 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.

Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan.

 (b) Type of Option. If Options are granted pursuant to
this Section they will be Nonstatutory Stock Options and, except as otherwise provided herein, will be subject to the other terms and conditions of the Plan. 
 (c) No Discretion. No person will have any discretion to select which Outside Directors will be granted Awards under this Section
or to determine the number of Shares to be covered by such Awards (except as provided in Sections 11(g) and 14). 
 (d)
Initial Award. Each person who is an Outside Director on the Registration Date will be automatically granted an Option for 20,000 Shares (the “Initial Award”) with an exercise price equal to the initial price to the public as set
forth in the final prospectus including within the registration statement on Form S-1 filed with the Securities and Exchange Commission for the initial public offering of the Company’s Common Stock. Thereafter, when each person first becomes an
Outside Director following the Registration Date, they will be automatically granted an Option for 20,000 Shares (also an “Initial Award”) on or about the date on which such person first becomes an Outside Director, whether through
election by the stockholders of the Company or appointment by the Board to fill a vacancy; provided, however, that an Inside Director who ceases to be an Inside Director, but who remains a Director, will not receive an Initial Award. 
 (e) Annual Award. Each Outside Director will be automatically granted an Option for 6,750 Shares (an “Annual Award”) on
each date of the annual meeting of the stockholders of the Company beginning in 2007, if as of such date, he or she will have served on the Board for at least the preceding six (6) months. 
 (f) Terms. The terms of each Award granted pursuant to this Section will be as follows: 
 (i) The term of the Award will be ten (10) years. 
  

 -13- 








 (ii) The exercise price for Shares subject to Awards will be 100% of the Fair Market
Value on the grant date. 
 (iii) Subject to Section 14, the Initial Award will vest and become exercisable as to one
thirty-sixth (1/36) of the Shares per month, so as to be 100% vested on the third anniversary of the grant date, provided that the Participant continues to serve as a Director through each such date. 
 (iv) Subject to Section 14, the Annual Award will vest and become exercisable as to one thirty-sixth (1/36) of the Shares per
month, so as to be 100% vested on the third anniversary of the grant date, provided that the Participant continues to serve as a Director through such date. 
 (g) Adjustments. The Administrator in its discretion may change and otherwise revise the terms of Awards granted under this
Section 11, including, without limitation, the number of Shares and exercise prices thereof, for Awards granted on or after the date the Administrator determines to make any such change or revision. 
 12. 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 ninety (90) days, 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 91st 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 transferable, such Award will contain such additional terms and conditions as the
Administrator deems appropriate. 
 14. 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, the numerical Share limits in Section 3 of the Plan and the number of Shares issuable pursuant to Awards
to be granted under Section 11. 
  

 -14- 








 (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. 
 (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 be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor
corporation. The Administrator shall 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 SARs, 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 100% on-target
levels and all other terms and conditions met. In addition, if an Option or SAR 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 SAR will
be exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or SAR 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 SAR 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 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
(unless such 

  

 -15- 








 
resignation is at the request of the acquirer), then the Participant will fully vest in and have the right to exercise Options and/or SARs as to all of the
Shares underlying such Award, including those Shares which would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Performance Units and Performance Shares, all
performance goals or other vesting criteria will be deemed achieved at 100% on-target levels and all other terms and conditions met. 
 15.
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 by
(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 to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.

 16. 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. 
 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 its adoption by the
Board. 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
Board 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. 
  

 -16- 








 (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. 
 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, 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. 
 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.
