 -4-









 
(ii) any Shares subject to stock options granted under the Company’s Amended and Restated 2001 Stock Plan (the “2001 Plan”) that expire or otherwise terminate on or
after January 1, 2010 without having been exercised in full up to a maximum of 1,411,562 Shares. 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 2011 Fiscal Year, in an amount equal to the least of (A) 3,500,000 Shares, (B) five percent (5%) of the outstanding Shares on the last day of the immediately preceding Fiscal

the Company due to failure to vest, 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 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 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 15,
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, to the extent allowable under Section 422 of the Code and the Treasury
Regulations promulgated thereunder, any Shares that become available for issuance under the Plan pursuant to Section 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. 

  
 -5-









 (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. Notwithstanding the foregoing sentence, the Administrator may not institute an Exchange Program without
stockholder approval; 
 (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 20(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 16; 
 (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; 

  
 -6-









 (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 pursuant to such procedures as the Administrator may determine; and 
 (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, 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. 

(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 one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a)(i), 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 Administrator will have complete discretion to determine the number of Shares subject to an Option granted to any
Participant, provided that during any Fiscal Year, no Participant will be granted an Option covering more than 3,500,000 Shares. 
 (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. 

  
 -7-









 (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. 

(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) 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 said 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; (4) consideration received by the Company under a broker-assisted (or other) cashless exercise program implemented by
the Company in connection with the Plan; (5) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (6) 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 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 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 dividend or other right for which the record date is prior to the
date the Shares are issued, except as provided in Section 15 of the Plan. 

  
 -8-









 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 such Option may be exercised by the personal
representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the laws of descent and distribution. In the absence of a specified time in the Award
Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the Administrator, if at the time of death Participant is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan.

 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. 

  
 -9-









 
Notwithstanding the foregoing sentence, for Restricted Stock intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, during any
Fiscal Year, no Participant will receive more than an aggregate of 1,200,000 Shares of Restricted Stock. 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 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. 
 (i) Section 162(m) Performance Restrictions. For purposes of
qualifying grants 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. The Performance
Goals will be set by the Administrator on or before the Determination Date. In granting Restricted Stock which is 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 Award under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 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 shall advise the Participant in an Award Agreement of
the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units and the form of payout, which, subject to Section 8(d), may be left to the discretion of the Administrator. Notwithstanding anything to
the contrary in this subsection (a), for Restricted Stock Units intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, during any Fiscal Year of the Company, no Participant will
receive more than an aggregate of 1,200,000 Restricted Stock Units. 

  
 -10-









 (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 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 shall 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
shall be forfeited to the Company. 
 (f) Section 162(m) Performance Restrictions. For purposes of
qualifying grants of 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. The
Performance Goals will be set by the Administrator on or before the Determination Date. In granting Restricted Stock Units 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 Award under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 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 Participant; provided, however, that no Participant will be granted, in any Fiscal Year, Stock Appreciation Rights covering more than 1,200,000 Shares. 

(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 shall be determined by the Administrator and shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant, except that Stock Appreciation Rights 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. 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 Stock Appreciation Rights granted under the Plan. 

  
 -11-









 (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. 

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;
provided that during any Fiscal Year, for Performance Units or Performance Shares intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, (i) no Participant will receive
Performance Units having an initial value greater than $1,000,000, and (ii) no Participant will receive more than 1,200,000 Performance Shares. 
 (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. 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 

  
 -12-









 
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. 

(g) Section 162(m) Performance Restrictions. 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 set restrictions based upon the achievement of Performance Goals. The Performance Goals will be set by the Administrator 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 Award under Section 162(m) of the Code (e.g., in determining the Performance Goals). 
 11. Formula Awards to Outside Directors. 
 (a)
General. Outside Directors will be entitled to receive all types of Awards (except Incentive Stock Options) under this Plan, including discretionary Awards not covered under this Section 11. All grants of Awards to Outside Directors
pursuant to this Section will be automatic and nondiscretionary, except as otherwise provided herein, and will be made in accordance with the following provisions: 

(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(d), 11(g) and 15).

 (d) Initial Award. Each person who first becomes an Outside Director following the Registration Date
will be granted an Option to purchase such number of Shares as determined by the Administrator in its sole discretion (the “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. Nothing in this Section 11(d) shall obligate the Administrator to grant an Initial Award if it should determine in its discretion not to do so.

 (e) Annual Award. Each Outside Director will be automatically granted an Option to purchase 20,000
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 ten (10) months.


  
 -13-









 (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. 

(ii) The exercise price for Shares subject to Awards will be one hundred percent (100%) of the Fair Market Value on
the grant date. 
 (iii) Subject to Section 15, the Initial Award will vest and become exercisable as the
Administrator determines in its sole discretion. 
 (iv) Subject to Section 15, the Annual Award will vest
and become exercisable as to one hundred percent (100%) of the Shares subject to such Award on the day prior to the next year’s annual stockholder meeting (but in no event later than December 31 of the calendar year following the
calendar year during which the Annual Award was granted), 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. Performance-Based Compensation Under Code Section 162(m). 
 (a) General. If the Administrator, in its discretion, decides to grant an Award intended to qualify as “performance-based compensation” under Code Section 162(m), the provisions of
this Section 12 will control over any contrary provision in the Plan; provided, however, that the Administrator may in its discretion grant Awards that are not intended to qualify as “performance-based compensation” under
Section 162(m) of the Code to such Participants that are based on Performance Goals or other specific criteria or goals but that do not satisfy the requirements of this Section 12. 

(b) Performance Goals. The granting and/or vesting of Awards of Restricted Stock, Restricted Stock Units,
Performance Shares and Performance Units and other incentives under the Plan may be made subject to the attainment of performance goals relating to one or more business criteria within the meaning of Code Section 162(m) and may provide for a
targeted level or levels of achievement (“Performance Goals”) including attainment of research and development milestones, bookings, cash flow, cash position, contract awards or backlog, customer renewals, earnings (which may
include earnings before interest and taxes; earnings before taxes; net earnings; and earnings before interest, taxes, depreciation and amortization), earnings per Share, expense reduction, gross margin, growth with respect to any of the foregoing
measures, growth in bookings, growth in revenues, growth in stockholder value relative to the moving average of the S&P 500 Index or another index, internal rate of return, market share, net income, net profit, net sales, new product
development, new product invention or innovation, number of customers, operating cash flow, operating expenses, operating income (GAAP and non-GAAP), operating margin, pre-tax profit, product release timelines, productivity, profit, return on
assets, return on capital, return on stockholder equity, return on investment, return on sales, revenue, revenue growth, sales results, sales growth, stock price increase, time to market, total stockholder return, and working capital. Any
Performance Goals may be used to measure the performance of the Company as a whole or a business unit of the Company and may be measured relative to a peer group or index. 

  
 -14-









 
The Performance Goals may differ from Participant to Participant and from Award to Award. Prior to the Determination Date, the Administrator will determine whether any significant element(s) will
be included in or excluded from the calculation of any Performance Goal with respect to any Participant. 
 (c)
Procedures. To the extent necessary to comply with the performance-based compensation provisions of Code Section 162(m), with respect to any Award granted subject to Performance Goals, within the first twenty-five percent (25%) of
the Performance Period, but in no event more than ninety (90) days following the commencement of any Performance Period (or such other time as may be required or permitted by Code Section 162(m)), the Administrator will, in writing:
(i) designate one or more Participants to whom an Award will be made, (ii) select the Performance Goals applicable to the Performance Period, (iii) establish the Performance Goals, and amounts of such Awards, as applicable, which may
be earned for such Performance Period, and (iv) specify the relationship between Performance Goals and the amounts of such Awards, as applicable, to be earned by each Participant for such Performance Period. Following the completion of each
Performance Period, the Administrator will certify in writing whether the applicable Performance Goals have been achieved for such Performance Period. In determining the amounts earned by a Participant, the Administrator will have the right to
reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Administrator may deem relevant to the assessment of individual or corporate performance for the
Performance Period. A Participant will be eligible to receive payment pursuant to an Award for a Performance Period only if the Performance Goals for such period are achieved. 

(d) Additional Limitations. Notwithstanding any other provision of the Plan, any Award which is granted to a
Participant and is intended to constitute qualified “performance-based compensation” under Code Section 162(m) will be subject to any additional limitations set forth in the Code (including any amendment to Section 162(m)) or any
regulations and ruling issued thereunder that are requirements for qualification as qualified “performance-based compensation” as described in Section 162(m) of the Code, and the Plan will be deemed amended to the extent necessary to
conform to such requirements. 
 13. 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 and one (1) day following the commencement of such leave any Incentive Stock Option held by the Participant
will cease to be treated as an Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 

14. 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. 

  
 -15-









 15. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other
securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the
corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will adjust the number and class of
Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by each outstanding Award, the numerical Share limits set forth in Sections 3, 6, 7, 8, 9 and 10 of the Plan, and the number of Shares issuable
pursuant to Awards to be granted under Section 11 of the Plan. 
 (b) Dissolution or Liquidation. In
the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised,
an Award will terminate immediately prior to the consummation of such proposed action. 
 (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 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 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
fully vested and exercisable for a period of time determined by the Administrator in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 

For the purposes of this subsection (c), an Award will be considered assumed if, following the Change in Control, the
Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) 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 15(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. 

  
 -16-









 (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 resignation is at the request of the acquirer), 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 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 one hundred percent (100%) of target levels and all other terms and conditions met. 
 16. Tax. 
 (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 (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash or Shares having a Fair Market Value equal to the minimum statutory amount required to be
withheld, or (iii) 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. 
 (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. 
 17. 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. 
 18. Date of Grant.
The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to
each Participant within a reasonable time after the date of such grant. 

  
 -17-









 19. 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 until November 22, 2016, a term of ten (10) years from the date initially adopted by the Board, unless terminated earlier under Section 20 of the Plan. 

20. 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. 
 (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. 

21. 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. 
 22. 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. 

23. Stockholder Approval. The Plan, as last amended and restated, will be subject to approval by the stockholders of the Company
within twelve (12) months after the date the Plan, as last amended and restated, is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.
