are subject to the provisions of this Plan. 
 (b) So long as the Company has registered a class of equity securities
under Section 12 of the Exchange Act, the Committee shall consist of Company Directors who are “Non-Employee Directors” as defined in Rule 16b-3 and, after the expiration of any transition period permitted by Treasury Regulations

 4.3 Scope of Discretion. Subject to the provisions of this Section 4.3, on all matters for which this Plan confers the authority, right or power on the Board, the Committee, or other
Administrator to make decisions, that body may make those decisions in its sole and absolute discretion. Those decisions will be final, binding and conclusive. In making its decisions, the Board, Committee or other Administrator need not treat all
persons eligible to receive Awards, all Awardees, all Awards or all Award Shares the same way. Notwithstanding anything herein to the contrary, and except as provided in Section 13.3, the discretion of the Board, Committee or other
Administrator is subject to the specific provisions and specific limitations of this Plan, as well as all rights conferred on specific Awardees by Award Agreements and other agreements. 

 

	5.	Persons Eligible to Receive Awards 

 5.1 Eligible Individuals. Awards (including Substitute Awards) may be granted to, and only to, Employees, Directors and Consultants, including to prospective Employees, Directors and Consultants
conditioned on the beginning of their service for the Company or an Affiliate. However, Incentive Stock Options may only be granted to Employees, as provided in Section 7(g). 

5.2 Section 162(m) Limitation. 
 (a) Options and SARs. Subject to the provisions of this Section 5.2, for so long as the Company is a “publicly held corporation” within the meaning of Section 162(m) of
the Code: (i) no Employee may be granted one or more SARs and Options within any fiscal year of the Company under this Plan to purchase more than 202,4013 Shares under Options or to receive compensation calculated with reference to more than that number of Shares under
SARs, subject to adjustment pursuant to Section 10, (ii) Options and SARs may be granted to an Executive only by the Committee (and, notwithstanding anything to the contrary in Section 4.1(a), not by the Board). If an Option or SAR is
cancelled without being exercised or if the Option Price of an Option is reduced, 
  

	3 	Reflects stock splits effective January 26, 2005 and August 20, 2008. 


  
 6 








 
that cancelled or repriced Option or SAR shall continue to be counted against the limit on Awards that my be granted to any individual under this Section 5.2. Notwithstanding anything herein
to the contrary, a new Employee of the Company or an Affiliate shall be eligible to receive up to a maximum of
303,6014 Shares under Options in the calendar year which
they commence employment, or such compensation calculated with reference to such number of Shares under SARs, subject to adjustment pursuant to Section 10. 
 (b) Cash Awards and Stock Awards. Any Cash Award or Stock Award intended as “qualified performance-based compensation” within the meaning of Section 162(m) of the Code must
vest or become exercisable contingent on the achievement of one or more Objectively Determinable Performance Conditions. The Committee shall have the discretion to determine the time and manner of compliance with Section 162(m) of the Code.

  

	6.	Terms and Conditions of Options 

 The following rules apply to all Options: 
 6.1 Price. Except as
specifically provided herein, no Nonstatutory Option may have an Option Price less than 85% of the Fair Market Value of the Shares on the Grant Date. No Option intended as “qualified incentive-based compensation” within the meaning of
Section 162(m) of the Code may have an Option Price less than 100% of the Fair Market Value of the Shares on the Grant Date. In no event will the Option Price of any Option be less than the par value of the Shares issuable under the Option if
that is required by Applicable Law. The Option Price of an Incentive Stock Option shall be subject to Section 7(f). 

6.2 Term. No Option shall be exercisable after its Expiration Date. No Option may have an Expiration Date that is more than ten
years after its Grant Date. Additional provisions regarding the term of Incentive Stock Options are provided in Sections 7(a) and 7(e). 
 6.3 Vesting. Options shall be exercisable: (a) on the Grant Date, or (b) in accordance with a schedule related to the Grant Date, the date the Optionee’s directorship, employment or
consultancy begins, or a different date specified in the Option Agreement. Additional provisions regarding the vesting of Incentive Stock Options are provided in Section 7(c). No Option granted to an individual who is subject to the overtime
pay provisions of the Fair Labor Standards Act may be exercised before the expiration of six months after the Grant Date. 

6.4 Form and Method of Payment. 
 (a) The Board or Committee shall determine the acceptable form and method of payment for exercising an Option. So long as variable accounting pursuant to “APB 25” does not apply and the
Board or Committee otherwise determines there is no material adverse accounting consequence at the time of exercise, the Board or Committee may require the delivery in Shares for the value of the net appreciation of the Shares at the time of
exercise over the exercise price. The difference between full number of Shares covered by the exercised portion of the Award and the number of Shares actually delivered shall be restored to the amount of Shares reserved for issuance under
Section 3.1. 
 (b) Acceptable forms of payment for all Option Shares are cash, check or wire transfer, denominated
in U.S. dollars except as specified by the Administrator for non-U.S. Employees or non-U.S. sub-plans. 
 (c) In
addition, the Administrator may permit payment to be made by any of the following methods: 
 (i) other Shares, or the
designation of other Shares, which (A) are “mature” shares for purposes of avoiding variable accounting treatment under generally accepted accounting principles (generally mature shares are those that have been owned by the
Optionee 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 Option Price of the Shares as to which the Option is being exercised;

 7 








 (ii) provided that a public market exists for the Shares, consideration received by
the Company under a procedure under which a licensed broker-dealer advances funds on behalf of an Optionee or sells Option Shares on behalf of an Optionee (a “Cashless Exercise Procedure”), provided that if the Company
extends or arranges for the extension of credit to an Optionee under any Cashless Exercise Procedure, no Officer or Director may participate in that Cashless Exercise Procedure; 

(iii) cancellation of any debt owed by the Company or any Affiliate to the Optionee by the Company including without limitation
waiver of compensation due or accrued for services previously rendered to the Company; and 
 (iv) any combination of
the methods of payment permitted by any paragraph of this Section 6.4. 
 (d) The Administrator may also permit any
other form or method of payment for Option Shares permitted by Applicable Law. 
 6.5 Nonassignability of Options. Except
as determined by the Administrator, no Option shall be assignable or otherwise transferable by the Optionee except by will or by the laws of descent and distribution. However, Options may be transferred and exercised in accordance with a Domestic
Relations Order and may be exercised by a guardian or conservator appointed to act for the Optionee. Incentive Stock Options may only be assigned in compliance with Section 7(h). 

6.6 Substitute Options. The Board may cause the Company to grant Substitute Options in connection with the acquisition by the
Company or an Affiliate of equity securities of any entity (including by merger, tender offer, or other similar transaction) or of all or a portion of the assets of any entity. Any such substitution shall be effective on the effective date of the
acquisition. Substitute Options may be Nonstatutory Options or Incentive Stock Options. Unless and to the extent specified otherwise by the Board, Substitute Options shall have the same terms and conditions as the options they replace, except that
(subject to the provisions of Section 10) Substitute Options shall be Options to purchase Shares rather than equity securities of the granting entity and shall have an Option Price determined by the Board. 

6.7 Repricings. Options may be repriced, replaced or regranted through cancellation or modification. 

 

	7.	Incentive Stock Options. 

 The following rules apply only to Incentive Stock Options and only to the extent these rules are more restrictive than the rules that would otherwise apply under this Plan. With the consent of the
Optionee, or where this Plan provides that an action may be taken notwithstanding any other provision of this Plan, the Administrator may deviate from the requirements of this Section, notwithstanding that any Incentive Stock Option modified by the
Administrator will thereafter be treated as a Nonstatutory Option. 
 (a) The Expiration Date of an Incentive Stock
Option shall not be later than ten years from its Grant Date, with the result that no Incentive Stock Option may be exercised after the expiration of ten years from its Grant Date. 

(b) No Incentive Stock Option may be granted more than ten years from the date this Plan was approved by the Board. 

(c) Options intended to be incentive stock options under Section 422 of the Code that are granted to any single Optionee
under all incentive stock option plans of the Company and its Affiliates, including incentive stock options granted under this Plan, may not vest at a rate of more than $100,000 in Fair Market Value of stock (measured on the grant dates of the
options) during any calendar year. For this purpose, an option vests with respect to a given share of stock the first time its holder may purchase that share, notwithstanding any right of the Company to repurchase that share. Unless the
administrator of that option plan specifies otherwise in the related agreement governing the option, this vesting limitation shall be applied by, to the extent necessary to satisfy this $100,000 rule, treating certain stock options that were
intended to be incentive stock options under Section 422 of the Code as Nonstatutory Options. The stock options or portions of stock options to be reclassified as Nonstatutory 

  
 8 








 
Options are those with the highest option prices, whether granted under this Plan or any other equity compensation plan of the Company or any Affiliate that permits that treatment. This
Section 7(c) shall not cause an Incentive Stock Option to vest before its original vesting date or cause an Incentive Stock Option that has already vested to cease to be vested. 

(d) In order for an Incentive Stock Option to be exercised for any form of payment other than those described in
Section 6.4(b), that right must be stated at the time of grant in the Option Agreement relating to that Incentive Stock Option. 
 (e) Any Incentive Stock Option granted to a Ten Percent Stockholder, must have an Expiration Date that is not later than five years from its Grant Date, with the result that no such Option may be
exercised after the expiration of five years from the Grant Date. A “Ten Percent Stockholder” is any person who, directly or by attribution under Section 424(d) of the Code, owns stock possessing more than ten
percent of the total combined voting power of all classes of stock of the Company or of any Affiliate on the Grant Date. 

(f) The Option Price of an Incentive Stock Option shall never be less than the Fair Market Value of the Shares at the Grant Date.
The Option Price for the Shares covered by an Incentive Stock Option granted to a Ten Percent Stockholder shall never be less than 110% of the Fair Market Value of the Shares at the Grant Date. 

(g) Incentive Stock Options may be granted only to Employees. If an Optionee changes status from an Employee to a Consultant, that
Optionee’s Incentive Stock Options become Nonstatutory Options if not exercised within the time period described in Section 7(i) (determined by treating that change in status as a Termination solely for purposes of this
Section 7(g)). 
 (h) No rights under an Incentive Stock Option may be transferred by the Optionee, other than by
will or the laws of descent and distribution. During the life of the Optionee, an Incentive Stock Option may be exercised only by the Optionee. The Company’s compliance with a Domestic Relations Order, or the exercise of an Incentive Stock
Option by a guardian or conservator appointed to act for the Optionee, shall not violate this Section 7(h). 
 (i)
An Incentive Stock Option shall be treated as a Nonstatutory Option if it remains exercisable after, and is not exercised within, the three-month period beginning with the Optionee’s Termination for any reason other than the Optionee’s
death or disability (as defined in Section 22(e) of the Code). In the case of Termination due to death, an Incentive Stock Option shall continue to be treated as an Incentive Stock Option if it remains exercisable after, and is not exercised
within, the three month period after the Optionee’s Termination provided it is exercised before the Expiration Date. In the case of Termination due to disability, an Incentive Stock Option shall be treated as a Nonstatutory Option if it remains
exercisable after, and is not exercised within, one year after the Optionee’s Termination. 
 (j) An Incentive Stock
Option may only be modified by the Board. 
  

	8.	Stock Appreciation Rights, Stock Awards and Cash Awards 

 8.1 Stock Appreciation Rights. The following rules apply to SARs: 
 (a)
General. SARs may be granted either alone, in addition to, or in tandem with other Awards granted under this Plan. The Administrator may grant SARs to eligible participants subject to terms and conditions not inconsistent with this
Plan and determined by the Administrator. The specific terms and conditions applicable to the Awardee shall be provided for in the Award Agreement. SARs shall be exercisable, in whole or in part, at such times as the Administrator shall specify in
the Award Agreement. The grant or vesting of a SAR may be made contingent on the achievement of Objectively Determinable Performance Conditions. 
 (b) Exercise of SARs. Upon the exercise of an SAR, in whole or in part, an Awardee shall be entitled to a payment in an amount equal to the excess of the Fair Market Value of a fixed
number of Shares covered by the exercised portion of the SAR on the date of exercise, over the Fair Market Value of the Shares covered by the exercised portion of the SAR on the Grant Date. The amount due to the Awardee upon the exercise of a SAR
shall be paid in cash, Shares or a combination thereof, over the period or periods specified in the Award

Agreement. An Award Agreement may place limits on the amount that may be paid over any specified period or periods upon the exercise of a SAR, on an aggregate basis or as to any Awardee. A SAR
shall be considered exercised when the Company receives written notice of exercise in accordance with the terms of the Award Agreement from the person entitled to exercise the SAR. If a SAR has been granted in tandem with an Option, upon the
exercise of the SAR, the number of shares that may be purchased pursuant to the Option shall be reduced by the number of shares with respect to which the SAR is exercised. 
 (c) Nonassignability of SARs. Except as determined by the Administrator, no SAR shall be assignable or otherwise transferable by the Awardee except by will or by the laws of descent
and distribution. Notwithstanding anything herein to the contrary, SARs may be transferred and exercised in accordance with a Domestic Relations Order. 
 (d) Substitute SARs. The Board may cause the Company to grant Substitute SARs in connection with the acquisition by the Company or an Affiliate of equity securities of any entity
(including by merger) or all or a portion of the assets of any entity. Any such substitution shall be effective on the effective date of the acquisition. Unless and to the extent specified otherwise by the Board, Substitute SARs shall have the same
terms and conditions as the options they replace, except that (subject to the provisions of Section 9) Substitute SARs shall be exercisable with respect to the Fair Market Value of Shares rather than equity securities of the granting entity and
shall be on terms that, as determined by the Board in its sole and absolute discretion, properly reflects the substitution. 

(e) Repricings. A SAR may be repriced, replaced or regranted, through cancellation or modification. 

8.2 Stock Awards. The following rules apply to all Stock Awards: 

(a) General. The specific terms and conditions of a Stock Award applicable to the Awardee shall be provided for in
the Award Agreement. The Award Agreement shall state the number of Shares that the Awardee shall be entitled to receive or purchase, the terms and conditions on which the Shares shall vest, the price to be paid, whether Shares are to be delivered at
the time of grant or at some deferred date specified in the Award Agreement, whether the Award is payable solely in Shares, cash or either and, if applicable, the time within which the Awardee must accept such offer. The offer shall be accepted by
execution of the Award Agreement. The Administrator may require that all Shares subject to a right of repurchase or risk of forfeiture be held in escrow until such repurchase right or risk of forfeiture lapses. The grant or vesting of a Stock Award
may be made contingent on the achievement of Objectively Determinable Performance Conditions. 
 (b) Right of
Repurchase. If so provided in the Award Agreement, Award Shares acquired pursuant to a Stock Award may be subject to repurchase by the Company or an Affiliate if not vested in accordance with the Award Agreement. 

(c) Form of Payment. The Administrator shall determine the acceptable form and method of payment for exercising
a Stock Award. Acceptable forms of payment for all Award Shares are cash, check or wire transfer, denominated in U.S. dollars except as specified by the Administrator for non-U.S. sub-plans. In addition, the Administrator may permit payment to be
made by any of the methods permitted with respect to the exercise of Options pursuant to Section 6.4. 
 (d)
Nonassignability of Stock Awards. Except as determined by the Administrator, no Stock Award shall be assignable or otherwise transferable by the Awardee except by will or by the laws of descent and distribution. Notwithstanding
anything to the contrary herein, Stock Awards may be transferred and exercised in accordance with a Domestic Relations Order. 

(e) Substitute Stock Award. The Board may cause the Company to grant Substitute Stock Awards in connection with the
acquisition by the Company or an Affiliate of equity securities of any entity (including by merger) or all or a portion of the assets of any entity. Unless and to the extent specified otherwise by the Board, Substitute Stock Awards shall have the
same terms and conditions as the stock awards they replace, except that (subject to the provisions of Section 10) Substitute Stock Awards shall be Stock Awards to purchase Shares rather than equity securities of the granting entity and shall
have a Purchase Price that, as determined by the 

  
 10 









 
Board in its sole and absolute discretion, properly reflects the substitution. Any such Substituted Stock Award shall be effective on the effective date of the acquisition. 

8.3 Cash Awards. The following rules apply to all Cash Awards: 

Cash Awards may be granted either alone, in addition to, or in tandem with other Awards granted under this Plan. After the Administrator
determines that it will offer a Cash Award, it shall advise the Awardee, by means of an Award Agreement, of the terms, conditions and restrictions related to the Cash Award. 

 

	9.	Exercise of Awards 


9.1 In General. An Award shall be exercisable in accordance with this Plan and the Award Agreement under which it is granted.

 9.2 Time of Exercise. Options and Stock Awards shall be considered exercised when the Company receives:
(a) written notice of exercise from the person entitled to exercise the Option or Stock Award, (b) full payment, or provision for payment, in a form and method approved by the Administrator, for the Shares for which the Option or Stock
Award is being exercised, and (c) with respect to Nonstatutory Options, payment, or provision for payment, in a form approved by the Administrator, of all applicable withholding taxes due upon exercise. An Award may not be exercised for a
fraction of a Share. SARs shall be considered exercised when the Company receives written notice of the exercise from the person entitled to exercise the SAR. 
 9.3 Issuance of Award Shares. The Company shall issue Award Shares in the name of the person properly exercising the Award. If the Awardee is that person and so requests, the Award Shares shall be
issued in the name of the Awardee and the Awardee’s spouse. The Company shall endeavor to issue Award Shares promptly after an Award is exercised or after the Grant Date of a Stock Award, as applicable. Until Award Shares are actually issued,
as evidenced by the appropriate entry on the stock register of the Company or its transfer agent, the Awardee will not have the rights of a stockholder with respect to those Award Shares, even though the Awardee has completed all the steps necessary
to exercise the Award. No adjustment shall be made for any dividend, distribution, or other right for which the record date precedes the date the Award Shares are issued, except as provided in Section 10. 

9.4 Termination 
 (a) In General. Except as provided in an Award Agreement or in writing by the Administrator, including in an Award Agreement, and as otherwise provided in Sections 9.4(b), (c),
(d) and (e) after an Awardee’s Termination for other than Cause, the Awardee’s Awards shall be exercisable to the extent (but only to the extent) they are vested on the date of that Termination and only during the
ninety (90) days after the Termination, but in no event after the Expiration Date. Unless otherwise provided in the Award Agreement, in the event of termination for Cause the Award may not be exercised after the date of Termination. To the
extent the Awardee does not exercise an Award within the time specified for exercise, the Award shall automatically terminate. 

(b) Leaves of Absence. Unless otherwise provided in the Award Agreement, no Award may be exercised more than three
months after the beginning of a leave of absence, other than a personal or medical leave approved by an authorized representative of the Company with employment guaranteed upon return. Awards shall not continue to vest during a leave of absence,
unless otherwise determined by the Administrator with respect to an approved personal or medical leave with employment guaranteed upon return. 
 (c) Death or Disability. Unless otherwise provided by the Administrator, if an Awardee’s Termination is due to death or disability (as determined by the Administrator with
respect to all Awards other than Incentive Stock Options and as defined by Section 22(e) of the Code with respect to Incentive Stock Options), all Awards of that Awardee to the extent exercisable at the date of that Termination may be exercised
for one year after that Termination, but in no event after the Expiration Date. In the case of Termination due to death, an Award may be exercised as provided in Section 16. In the case of Termination due to disability, if a guardian or
conservator has been appointed to act for the Awardee and been granted this authority as part of that appointment, that guardian or conservator may exercise the Award on behalf of the Awardee. Death or disability occurring after an Awardee’s


  
 11 









 
Termination shall not cause the Termination to be treated as having occurred due to death or disability. To the extent an Award is not so exercised within the time specified for its exercise, the
Award shall automatically terminate. 
 (d) Divestiture. If an Awardee’s Termination is due to a
Divestiture, the Board may take any one or more of the actions described in Section 10.3 or 10.4 with respect to the Awardee’s Awards. 
 (e) Administrator Discretion. Notwithstanding the provisions of Section 9.4(a)–(e), the Plan Administrator shall have complete discretion, exercisable either at the time an
Award is granted or at any time while the Award remains outstanding, to: 
 (i) Extend the period of time for which the
Award is to remain exercisable, following the Awardee’s Termination, from the limited exercise period otherwise in effect for that Award to such greater period of time as the Administrator shall deem appropriate, but in no event beyond the
Expiration Date; and/or 
 (ii) Permit the Award to be exercised, during the applicable post-Termination exercise
period, not only with respect to the number of vested Shares for which such Award may be exercisable at the time of the Awardee’s Termination but also with respect to one or more additional installments in which the Awardee would have vested
had the Awardee not been subject to Termination. 
 (f) Consulting or Employment Relationship. Nothing in
this Plan or in any Award Agreement, and no Award or the fact that Award Shares remain subject to repurchase rights, shall: (A) interfere with or limit the right of the Company or any Affiliate to terminate the employment or consultancy of any
Awardee at any time, whether with or without cause or reason, and with or without the payment of severance or any other compensation or payment, or (B) interfere with the application of any provision in any of the Company’s or any
Affiliate’s charter documents or Applicable Law relating to the election, appointment, term of office, or removal of a Director. 
  

	10.	Certain Transactions and Events 

 10.1 In General. Except as provided in this Section 10, no change in the capital structure of the Company, merger, sale or other disposition of assets or a subsidiary, change in control,
issuance by the Company of shares of any class of securities or securities convertible into shares of any class of securities, exchange or conversion of securities, or other transaction or event shall require or be the occasion for any adjustments
of the type described in this Section 10. Additional provisions with respect to the foregoing transactions are set forth in Section 13.3. 
 10.2 Changes in Capital Structure. In the event of any stock split, reverse stock split, recapitalization, combination or reclassification of stock, stock dividend, spin-off, or similar change to
the capital structure of the Company (not including a Fundamental Transaction or Change in Control), the Board shall make whatever adjustments it concludes are appropriate to: (a) the number and type of Awards that may be granted under this
Plan, (b) the number and type of Options that may be granted to any individual under this Plan, (c) the terms of any SAR, (d) the Purchase Price of any Stock Award, (e) the Option Price and number and class of securities issuable
under each outstanding Option, and (f) the repurchase price of any securities substituted for Award Shares that are subject to repurchase rights. The specific adjustments shall be determined by the Board. Unless the Board specifies otherwise,
any securities issuable as a result of any such adjustment shall be rounded down to the next lower whole security. The Board need not adopt the same rules for each Award or each Awardee. 

10.3 Fundamental Transactions. In the event of (a) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned subsidiary, a reincorporation of the Company in a different jurisdiction, or other transaction in which there is no substantial change in the stockholders of the Company or their
relative stock holdings and the Awards granted under this Plan are assumed, converted or replaced by the successor corporation, which assumption shall be binding on all Participants), (b) a merger in which the Company is the surviving
corporation but after which the stockholders of the Company immediately prior to such merger (other than any stockholder that merges, or which owns or controls another corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest 

  
 12 









 
in the Company, (c) the sale of all or substantially all of the assets of the Company, or (d) the acquisition, sale, or transfer of more than 50% of the outstanding shares of the
Company by tender offer or similar transaction (each, a “Fundamental Transaction”), any or all outstanding Awards may be assumed, converted or replaced by the successor corporation (if any), which assumption, conversion
or replacement shall be binding on all participants under this Plan. In the alternative, the successor corporation may substitute equivalent Awards or provide substantially similar consideration to participants as was provided to stockholders (after
taking into account the existing provisions of the Awards). The successor corporation may also issue, in place of outstanding Shares held by the participants, substantially similar shares or other property subject to repurchase restrictions no less
favorable to the participant. In the event such successor corporation (if any) does not assume or substitute Awards, as provided above, pursuant to a transaction described in this Subsection 10.3, the vesting with respect to such Awards shall
fully and immediately accelerate or the repurchase rights of the Company shall fully and immediately terminate, as the case may be, so that the Awards may be exercised or the repurchase rights shall terminate before, or otherwise in connection with
the closing or completion of the Fundamental Transaction or event, but then terminate. Notwithstanding anything in this Plan to the contrary, the Committee may, in its sole discretion, provide that the vesting of any or all Award Shares subject to
vesting or right of repurchase shall accelerate or lapse, as the case may be, upon a transaction described in this Section 10.3. If the Committee exercises such discretion with respect to Options, such Options shall become exercisable in full
prior to the consummation of such event at such time and on such conditions as the Committee determines, and if such Options are not exercised prior to the consummation of the Fundamental Transaction, they shall terminate at such time as determined
by the Committee. Subject to any greater rights granted to participants under the foregoing provisions of this Section 10.3, in the event of the occurrence of any Fundamental Transaction, any outstanding Awards shall be treated as provided in
the applicable agreement or plan of merger, consolidation, dissolution, liquidation, or sale of assets. 
 10.4 Changes of
Control. The Board may also, but need not, specify that other transactions or events constitute a “Change in Control.” The Board may do that either before or after the transaction or event occurs. Examples of transactions or events
that the Board may treat as Changes of Control are: (a) any person or entity, including a “group” as contemplated by Section 13(d)(3) of the Exchange Act, acquires securities holding 30% or more of the total combined voting power
or value of the Company, or (b) as a result of or in connection with a contested election of Company Directors, the persons who were Company Directors immediately before the election cease to constitute a majority of the Board. In connection
with a Change in Control, notwithstanding any other provision of this Plan, the Board may, but need not, take any one or more of the actions described in Section 10.3. In addition, the Board may extend the date for the exercise of Awards (but
not beyond their original Expiration Date). The Board need not adopt the same rules for each Award or each Awardee. Notwithstanding anything in this Plan to the contrary, in the event of an Involuntary Termination of services for any reason other
than death, disability or Cause, within 18 months following the consummation of a Fundamental Transaction or Change in Control, any Awards, assumed or substituted in a Fundamental Transaction or Change in Control, which are subject to vesting
conditions and/or the right of repurchase in favor of the Company or a successor entity, shall accelerate for 12 months of vesting so that such Award Shares are immediately exercisable upon Termination or, if subject to the right of repurchase
in favor of the Company, such repurchase rights shall lapse as of the date of Termination. Such Awards shall be exercisable for a period of three (3) months following termination. 

10.5 Divestiture. If the Company or an Affiliate sells or otherwise transfers equity securities of an Affiliate to a person or
entity other than the Company or an Affiliate, or leases, exchanges or transfers all or any portion of its assets to such a person or entity, then the Board may specify that such transaction or event constitutes a “Divestiture.” In
connection with a Divestiture, notwithstanding any other provision of this Plan, the Board may, but need not, take one or more of the actions described in Section 10.3 or 10.4 with respect to Awards of Award Shares held by, for example,
Employees, Directors or Consultants for whom that transaction or event results in a Termination. The Board need not adopt the same rules for each Award or Awardee. 
 10.6 Dissolution. If the Company adopts a plan of dissolution, the Board may cause Awards to be fully vested and exercisable (but not after their Expiration Date) before the dissolution is
completed but contingent on its completion and may cause the Company’s repurchase rights on Award Shares to lapse upon completion of the dissolution. The Board need not adopt the same rules for each Award or each Awardee. Notwithstanding
anything herein to the contrary, in the event of a dissolution of the Company, to the extent not exercised before the earlier of the completion of the dissolution or their Expiration Date, Awards shall terminate immediately prior to the dissolution.


  
 13 









 10.7 Cut-Back to Preserve Benefits. If the Administrator determines that the net
after-tax amount to be realized by any Awardee, taking into account any accelerated vesting, termination of repurchase rights, or cash payments to that Awardee in connection with any transaction or event set forth in this Section 10 would be
greater if one or more of those steps were not taken or payments were not made with respect to that Awardee’s Awards or Award Shares, then, at the election of the Awardee, to such extent, one or more of those steps shall not be taken and
payments shall not be made. 
  

	11.	Automatic Option Grants to Non-Employee Directors and Non-Employee Director Fee Option Grants 


11.1 Automatic Option Grants to Non-Employee Directors. 
 (a) Grant Dates. Option grants to Non-Employee Directors shall be made on the dates specified below: 
 (i) Each Non-Employee Director who is first elected or appointed to the Board at any time after the effective date of this Plan shall automatically be granted, on the date of such initial election
or appointment, an Option to purchase 25,0005 Shares
(the “Initial Grant”). 
 (ii) Commencing in 2005, on the date of each annual stockholders
meeting, each individual who is to continue to serve as a Non-Employee Director shall automatically be granted an Option to purchase 12,5006 Shares (the “Annual Grant”), provided, however, that such individual has served as a
Non-Employee Director for at least six (6) months. 
 (b) Exercise Price. 

(i) The Option Price shall be equal to one hundred percent (100%) of the Fair Market Value of the Shares on the Option grant
date. 
 (ii) The Option Price shall be payable in one or more of the alternative forms authorized pursuant to
Section 6.4. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the Option Price must be made on the date of exercise. 
 (c) Option Term. Each Option shall have a term of ten (10) years measured from the Option grant date. 
 (d) Exercise and Vesting of Options. Except as otherwise determined by the whole Board, the Shares underlying each Option granted pursuant to Section 11.1 shall vest and be
exercisable as set forth below. 
 (i) Initial Grant. The Shares underlying each Option issued pursuant to
the Initial Grant shall vest and be exercisable as to 2.7777% of the Shares on each monthly anniversary of the date of grant, rounded down to the nearest whole Share, for so long as the Non-Employee Director continuously remains a Director of,
or a Consultant to, the Company. 
 (ii) Annual Grant. The Shares underlying each Option issued pursuant
to the Annual Grant shall vest and be exercisable as to 8.3333% of the Shares on each monthly anniversary of the date of grant for the first 11 months following the date of grant and as to the remaining Shares on the date of the annual
stockholders meeting for the year following the year of grant for such Option, rounded down to the nearest whole Share, for so long as the Non-Employee Director continuously remains a Director of, or a Consultant to, the Company. 

(e) Termination of Service. The following provisions shall govern the exercise of any Options held by the Awardee at
the time the Awardee ceases to serve as a Non-Employee Director, Employee or Consultant:

	6 	Reflects amendments effective May 19, 2005, May 22, 2009 and May 19, 2010. 


  
 14 









 (i) In General. Except as otherwise provided in Section 10.3,
after cessation of service (the “Cessation Date”), the Awardee’s Options shall be exercisable to the extent (but only to the extent) they are vested on the Cessation Date and only during the three months after such
Cessation Date, but in no event after the Expiration Date. To the extent the Awardee does not exercise an Option within the time specified for exercise, the Option shall automatically terminate. 

(ii) Death or Disability. If an Awardee’s cessation of service is due to death or disability (as determined by
the Board), all Options of that Awardee, to the extent exercisable upon such Cessation Date, may be exercised for one year after the Cessation Date, but in no event after the Expiration Date. In the case of a cessation of service due to death, an
Option may be exercised as provided in Section 16. In the case of a cessation of service due to disability, if a guardian or conservator has been appointed to act for the Awardee and been granted this authority as part of that appointment, that
guardian or conservator may exercise the Option on behalf of the Awardee. Death or disability occurring after an Awardee’s cessation of service shall not cause the cessation of service to be treated as having occurred due to death or
disability. To the extent an Option is not so exercised within the time specified for its exercise, the Option shall automatically terminate. 
 (f) Board Discretion. The Awards under this Section 11.1 are not intended as the exclusive Awards that may be made to Non-Employee Directors under this Plan. The Board may, in
its discretion, amend the Plan with respect to the terms of the Awards herein, may add or substitute other types of Awards or may temporarily or permanently suspend Awards hereunder, all without approval of the Company’s stockholders.

 11.2 Director Fee Option Grants 
 (a) Option Grants. The Board shall have the sole and exclusive authority to determine the calendar year or years for which the Director fee option grant program
(the “Director Fee Option Program”) is to be in effect. For each such calendar year the program is in effect, each Non-Employee Director may elect to apply all or any portion of the annual retainer fee otherwise payable
in cash, for his or her service on the Board for that year, to the acquisition of a special Option grant under this Director Fee Option Program. Such election must be filed with the Company’s Chief Financial Officer prior to first day of the
calendar year for which the annual retainer fee which is the subject of that election is otherwise payable. Each Non-Employee Director who files such a timely election shall automatically be granted an Option under this Director Fee Option Program
on the first trading day in January in the calendar year for which the annual retainer fee which is the subject of that election would otherwise be payable in cash. 
 (b) Option Terms. Each Option shall be a Nonstatutory Option governed by the terms and conditions specified below. 

(i) Exercise Price. 
 A. The Purchase Price shall be thirty-three and one-third
percent (33 1/3%) of the Fair Market Value per
Share on the Option grant date. 
 B. The Purchase Price shall become immediately due upon exercise of the Option
and shall be payable in one or more of the alternative forms authorized pursuant to Section 6.4 of this Plan. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the Purchase Price must be made on
the date that the Option is exercised. 
 (ii) Number of Option Shares. The number of Shares subject to
the Option shall be determined pursuant to the following formula (rounded down to the nearest whole number): 
 X = A ÷ (B x 66 2/3%), where 
 X is the number of Option Shares, 

A is the portion of the annual retainer fee subject to the Non-Employee Director’s election, and 

B is the Fair Market Value of a Share on the option grant date. 

  
 15 









 (iii) Exercise and Term of Options. The Option shall become
exercisable in a series of twelve (12) equal monthly installments upon the Awardee’s completion of each month of Board service over the twelve (12)-month period measured from the grant date. Each Option shall have a maximum term of
ten (10) years measured from the Option grant date. 
 (iv) Termination of Board Service. Should
the Awardee cease Board service for any reason (other than death or permanent disability) while holding one or more Options under this Director Fee Option Program, then each such Option shall remain exercisable, for any or all of the Shares for
which the Option is exercisable at the time of such cessation of Board service, until the earlier of (x) the expiration of the ten (10)-year Option term or (y) the expiration of the three (3)-year period measured from the date of
such cessation of Board service. However, each Option held by the Awardee under this Director Fee Option Program at the time of his or her cessation of Board service shall immediately terminate and cease to remain outstanding with respect to any and
all Shares for which the Option is not otherwise at that time exercisable. 
 (v) Death or Permanent
Disability. Should the Awardee’s service as a Board member cease by reason of death or permanent disability, then each Option held by such Awardee under this Director Fee Option Program shall immediately become exercisable for all the
Shares at the time subject to that Option, and the Option may be exercised for any or all of those Shares as fully-vested Shares until the earlier of (x) the expiration of the ten (10)-year option term or (y) the expiration of the
three (3)-year period measured from the date of such cessation of Board service. 
 Should the Awardee die after cessation
of his or her Board service but while holding one or more Options under this Director Fee Option Program, then each such Option may be exercised, for any or all of the shares for which the Option is exercisable at the time of the Awardee’s
cessation of Board service (less any Shares subsequently purchased by the Awardee prior to death), by the personal representative of the Awardee’s estate or by the person or persons to whom the Option is transferred pursuant to the
Awardee’s will or in accordance with the laws of descent and distribution or by the designated beneficiary or beneficiaries of such option. Such right of exercise shall lapse, and the Option shall terminate, upon the earlier of (xx) the
expiration of the ten (10)-year Option term or (yy) the three (3)-year period measured from the date of the Awardee’s cessation of Board service. 
 11.3 Certain Transactions and Events 
 (a) In the event of a
Fundamental Transaction while the Awardee remains a Non-Employee Director, the Shares at the time subject to each outstanding Option held by such Awardee pursuant to Section 11, but not otherwise vested, shall automatically vest in full so that
each such Option shall, immediately prior to the effective date of the Fundamental Transaction, become exercisable for all the Shares as fully vested Shares and may be exercised for any or all of those vested Shares. Immediately following the
consummation of the Fundamental Transaction, each Option shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or Affiliate thereof). 

(b) In the event of a Change in Control while the Awardee remains a Non-Employee Director, the Shares at the time subject to each
outstanding Option held by such Awardee pursuant to Section 11, but not otherwise vested, shall automatically vest in full so that each such Option shall, immediately prior to the effective date of the Change in Control, become exercisable for
all the Shares as fully vested Shares and may be exercised for any or all of those vested Shares. Each such Option shall remain exercisable for such fully vested Shares until the expiration or sooner termination of the Option term in connection with
a Change in Control. 
 (c) Each Option which is assumed in connection with a Fundamental Transaction shall be
appropriately adjusted, immediately after such Fundamental Transaction, to apply to the number and class of securities which would have been issuable to the Awardee in consummation of such Fundamental Transaction had the Option been exercised
immediately prior to such Fundamental Transaction. Appropriate adjustments shall also be made to the Option Price payable per share under each outstanding Option, provided the aggregate Option Price payable for such securities shall remain the same.
To the extent the actual holders of the Company’s outstanding Common Stock receive cash consideration for their Common Stock in consummation of the Fundamental Transaction, the successor corporation may, in connection with the assumption of the
outstanding Options granted pursuant to Section 11, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per share of Common Stock in such Fundamental Transaction. 

  
 16 









 (d) The grant of Options pursuant to Section 11 shall in no way affect the right
of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 

(e) The remaining terms of each Option granted pursuant to Section 11 shall, as applicable, be the same as terms in effect
for Awards granted under this Plan. Notwithstanding the foregoing, the provisions of Section 9.4 and Section 10 shall not apply to Options granted pursuant to Section 11. 

11.4 Limited Transferability of Options. Each Option granted pursuant to Section 11 may be assigned in whole or in part
during the Awardee’s lifetime to one or more members of the Awardee’s family or to a trust established exclusively for one or more such family members or to an entity in which the Awardee is majority owner or to the Awardee’s former
spouse, to the extent such assignment is in connection with the Awardee’s estate or financial plan or pursuant to a Domestic Relations Order. The assigned portion may only be exercised by the person or persons who acquire a proprietary interest
in the Option pursuant to the assignment. The terms applicable to the assigned portion shall be the same as those in effect for the Option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the
Administrator may deem appropriate. The Awardee may also designate one or more persons as the beneficiary or beneficiaries of his or her outstanding Options under Section 11, and those Options shall, in accordance with such designation,
automatically be transferred to such beneficiary or beneficiaries upon the Awardee’s death while holding those Options. Such beneficiary or beneficiaries shall take the transferred Options subject to all the terms and conditions of the
applicable Award Agreement evidencing each such transferred Option, including (without limitation) the limited time period during which the Option may be exercised following the Awardee’s death. 

 

	12.	Withholding and Tax Reporting 

 12.1 Tax Withholding Alternatives 
 (a) General.
Whenever Award Shares are issued or become free of restrictions, the Company may require the Awardee to remit to the Company an amount sufficient to satisfy any applicable tax withholding requirement, whether the related tax is imposed on the
Awardee or the Company. The Company shall have no obligation to deliver Award Shares or release Award Shares from an escrow or permit a transfer of Award Shares until the Awardee has satisfied those tax withholding obligations. Whenever payment in
satisfaction of Awards is made in cash, the payment will be reduced by an amount sufficient to satisfy all tax withholding requirements. 
 (b) Method of Payment. The Awardee shall pay any required withholding using the forms of consideration described in Section 6.4(b), except that, in the discretion of the
Administrator, the Company may also permit the Awardee to use any of the forms of payment described in Section 6.4(c). The Administrator, in its sole discretion, may also permit Award Shares to be withheld to pay required withholding. If the
Administrator permits Award Shares to be withheld, the Fair Market Value of the Award Shares withheld, as determined as of the date of withholding, shall not exceed the amount determined by the applicable minimum statutory withholding rates.

 12.2 Reporting of Dispositions. Any holder of Option Shares acquired under an Incentive Stock Option shall promptly
notify the Administrator, following such procedures as the Administrator may require, of the sale or other disposition of any of those Option Shares if the disposition occurs during: (a) the longer of two years after the Grant Date of the
Incentive Stock Option and one year after the date the Incentive Stock Option was exercised, or (b) such other period as the Administrator has established. 
  

	13.	Compliance with Law 

 The
grant of Awards and the issuance and subsequent transfer of Award Shares shall be subject to compliance with all Applicable Law, including all applicable securities laws. Awards may not be exercised, and Award Shares may not be transferred, in
violation of Applicable Law. Thus, for example, Awards may not be exercised unless: (a) a registration statement under the Securities Act is then in effect with respect to the related Award Shares, or (b) in the opinion of legal counsel to
the Company, those Award Shares may be issued in accordance with an applicable exemption from the registration requirements of the Securities Act and any other applicable securities laws. The failure or inability of the Company to obtain from any
regulatory body the authority

considered by the Company’s legal counsel to be necessary or useful for the lawful issuance of any Award Shares or their subsequent transfer shall relieve the Company of any liability for
failing to issue those Award Shares or permitting their transfer. As a condition to the exercise of any Award or the transfer of any Award Shares, the Company may require the Awardee to satisfy any requirements or qualifications that may be
necessary or appropriate to comply with or evidence compliance with any Applicable Law. 
  

	14.	Amendment or Termination of this Plan or Outstanding Awards 

 14.1 Amendment and Termination. The Board may at any time amend, suspend, or terminate this Plan. 
 14.2 Stockholder Approval. The Company shall obtain the approval of the Company’s stockholders for any amendment to this Plan if stockholder approval is necessary or desirable to comply with
any Applicable Law or with the requirements applicable to the grant of Awards intended to be Incentive Stock Options. The Board may also, but need not, require that the Company’s stockholders approve any other amendments to this Plan.

 14.3 Effect. No amendment, suspension, or termination of this Plan, and no modification of any Award even in the
absence of an amendment, suspension, or termination of this Plan, shall impair any existing contractual rights of any Awardee unless the affected Awardee consents to the amendment, suspension, termination, or modification. Notwithstanding anything
herein to the contrary, no such consent shall be required if the Board determines, in its sole and absolute discretion, that the amendment, suspension, termination, or modification: (a) is required or advisable in order for the Company, this
Plan or the Award to satisfy Applicable Law, to meet the requirements of any accounting standard or to avoid any adverse accounting treatment, or (b) in connection with any transaction or event described in Section 10, is in the best
interests of the Company or its stockholders. The Board may, but need not, take the tax or accounting consequences to affected Awardees into consideration in acting under the preceding sentence. Those decisions shall be final, binding and
conclusive. Termination of this Plan shall not affect the Administrator’s ability to exercise the powers granted to it under this Plan with respect to Awards granted before the termination of Award Shares issued under such Awards even if those
Award Shares are issued after the termination. 
  

	15.	Reserved Rights 

 15.1
Nonexclusivity of this Plan. This Plan shall not limit the power of the Company or any Affiliate to adopt other incentive arrangements including, for example, the grant or issuance of stock options, stock, or other equity-based rights under
other plans. 
 15.2 Unfunded Plan. This Plan shall be unfunded. Although bookkeeping accounts may be established with
respect to Awardees, any such accounts will be used merely as a convenience. The Company shall not be required to segregate any assets on account of this Plan, the grant of Awards, or the issuance of Award Shares. The Company and the Administrator
shall not be deemed to be a trustee of stock or cash to be awarded under this Plan. Any obligations of the Company to any Awardee shall be based solely upon contracts entered into under this Plan, such as Award Agreements. No such obligations shall
be deemed to be secured by any pledge or other encumbrance on any assets of the Company. Neither the Company nor the Administrator shall be required to give any security or bond for the performance of any such obligations. 

 

	16.	Special Arrangements Regarding Award Shares 

 16.1 Escrow of Stock Certificates. To enforce any restrictions on Award Shares, the Administrator may require their holder to deposit the certificates representing Award Shares, with stock powers
or other transfer instruments approved by the Administrator endorsed in blank, with the Company or an agent of the Company to hold in escrow until the restrictions have lapsed or terminated. The Administrator may also cause a legend or legends
referencing the restrictions to be placed on the certificates. 
 16.2 Repurchase Rights 

(a) General. If a Stock Award is subject to vesting conditions, the Company shall have the right, during the seven
months after the Awardee’s Termination, to repurchase any or all of the Award Shares that 

  
 18 









 
were unvested as of the date of that Termination. The repurchase price shall be determined by the Administrator in accordance with this Section 16.2 which shall be either (i) the
Purchase Price for the Award Shares (minus the amount of any cash dividends paid or payable with respect to the Award Shares for which the record date precedes the repurchase) or (ii) the lower of (A) the Purchase Price for the Shares or
(B) the Fair Market Value of those Award Shares as of the date of the Termination. The repurchase price shall be paid in cash. The Company may assign this right of repurchase. 

(b) Procedure. The Company or its assignee may choose to give the Awardee a written notice of exercise of its
repurchase rights under this Section 16.2. However, the Company’s failure to give such a notice shall not affect its rights to repurchase Award Shares. The Company must, however, tender the repurchase price during the period specified in
this Section 16.2 for exercising its repurchase rights in order to exercise such rights. 
  

	17.	Beneficiaries 

 An Awardee
may file a written designation of one or more beneficiaries who are to receive the Awardee’s rights under the Awardee’s Awards after the Awardee’s death. An Awardee may change such a designation at any time by written notice. If an
Awardee designates a beneficiary, the beneficiary may exercise the Awardee’s Awards after the Awardee’s death. If an Awardee dies when the Awardee has no living beneficiary designated under this Plan, the Company shall allow the executor
or administrator of the Awardee’s estate to exercise the Award or, if there is none, the person entitled to exercise the Option under the Awardee’s will or the laws of descent and distribution. In any case, no Award may be exercised after
its Expiration Date. 
  

	18.	Miscellaneous 

 18.1
Governing Law. This Plan, the Award Agreements and all other agreements entered into under this Plan, and all actions taken under this Plan or in connection with Awards or Award Shares, shall be governed by the laws of the State of Delaware.

 18.2 Determination of Value. Fair Market Value shall be determined as follows: 

(a) Listed Stock. If the Shares are traded on any established stock exchange or quoted on a national market system,
Fair Market Value shall be the closing sales price for the Shares as quoted on that stock exchange or system for the date the value is to be determined (the “Value Date”) as reported in The Wall Street Journal or
a similar publication. If no sales are reported as having occurred on the Value Date, Fair Market Value shall be that closing sales price for the last preceding trading day on which sales of Shares are reported as having occurred. If no sales are
reported as having occurred during the five trading days before the Value Date, Fair Market Value shall be the closing bid for Shares on the Value Date. If Shares are listed on multiple exchanges or systems, Fair Market Value shall be based on sales
or bid prices on the primary exchange or system on which Shares are traded or quoted. 
 (b) Stock Quoted by
Securities Dealer. If Shares are regularly quoted by a recognized securities dealer but selling prices are not reported on any established stock exchange or quoted on a national market system, Fair Market Value shall be the mean between the
high bid and low asked prices on the Value Date. If no prices are quoted for the Value Date, Fair Market Value shall be the mean between the high bid and low asked prices on the last preceding trading day on which any bid and asked prices were
quoted. 
 (c) No Established Market. If Shares are not traded on any established stock exchange or quoted
on a national market system and are not quoted by a recognized securities dealer, the Administrator (following guidelines established by the Board or Committee) will determine Fair Market Value in good faith. The Administrator will consider the
following factors, and any others it considers significant, in determining Fair Market Value: (i) the price at which other securities of the Company have been issued to purchasers other than Employees, Directors, or Consultants, (ii) the
Company’s stockholder’s equity, prospective earning power, dividend-paying capacity, and non-operating assets, if any, and (iii) any other relevant factors, including the economic outlook for the Company and the Company’s
industry, the Company’s position in that industry, the Company’s goodwill and other intellectual property, and the values of securities of other businesses in the same industry.

 18.3 Reservation of Shares. During the term of this Plan, the Company shall at all
times reserve and keep available such number of Shares as are still issuable under this Plan. 
 18.4 Electronic
Communications. Any Award Agreement, notice of exercise of an Award, or other document required or permitted by this Plan may be delivered in writing or, to the extent determined by the Administrator, electronically. Signatures may also be
electronic if permitted by the Administrator. 
 18.5 Notices. Unless the Administrator specifies otherwise, any notice
to the Company under any Option Agreement or with respect to any Awards or Award Shares shall be in writing (or, if so authorized by Section 17.4, communicated electronically), shall be addressed to the Secretary of the Company, and shall only
be effective when received by the Secretary of the Company.
