 GIGAMON INC. 
 2013 EMPLOYEE STOCK PURCHASE PLAN 

1. Purpose. The purpose of the Plan is to provide employees of the Company and its Designated Subsidiaries with an opportunity to
purchase Common Stock through accumulated Contributions. The Company’s intention is to have the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code. The provisions of the Plan, accordingly, will be
construed so as to extend and limit Plan participation in a uniform and nondiscriminatory basis consistent with the requirements of Section 423 of the Code. 
 2. Definitions. 
 (a) “Administrator” means the Board or
any Committee designated by the Board to administer the Plan pursuant to Section 14. 
 (b) “Applicable
Laws” means the requirements relating to the administration of equity-based awards under U.S. state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed
or quoted and the applicable laws of any foreign country or jurisdiction where options are, or will be, granted under the Plan. 

(c) “Board” means the Board of Directors of the Company. 

(d) “Change in Control” means the occurrence of any of the following events: 

(i) A change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group
(“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company; provided, however,
that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered a Change in
Control; or 
 (ii) A change in the effective control of the Company which occurs on the date that a majority of members of the
Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this clause (ii), if
any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(e) A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any Person acquires (or

total gross fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or
acquisitions; provided, however, that for purposes of this subsection, the following will not constitute a change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the
Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to: (1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s
stock, (2) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the
total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least fifty percent (50%) of the total value or voting power of which is owned, directly or indirectly, by a Person described in this subsection
(iii)(B)(3). For purposes of this subsection, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 

For purposes of this definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into
a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 
 Notwithstanding
the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Code Section 409A, as it has been and may be amended from time to time, and any proposed or
final U.S. Treasury Regulations and Internal Revenue Service guidance that has been promulgated or may be promulgated thereunder from time to time. 
 Further and for the avoidance of doubt, a transaction will not constitute a Change in Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its
sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.

supplementing or superseding such section or regulation.

appointed in accordance with Section 14 hereof.

Company.

 (k) “Contributions” means the payroll
deductions and other additional payments that the Company may permit to be made by a Participant to fund the exercise of options granted pursuant to the Plan.

of any separate Offering. For purposes of the Plan, the employment relationship will be treated as continuing intact while the individual is on sick leave or other leave of absence that the Employer approves or is legally protected under Applicable
Laws. Where the period of leave exceeds three (3) months and the individual’s right to reemployment is not guaranteed either by statute or by contract, the employment relationship will be deemed to have terminated three (3) months and
one (1) day following the commencement of such leave. The Administrator, in its discretion, from time to time may, prior to an Enrollment Date for all options to be granted on such Enrollment Date in an Offering, determine (on a uniform and
nondiscriminatory basis or as otherwise permitted by Treasury Regulation Section 1.423-2) that the definition of Eligible Employee will or will not include an individual if he or she: (i) has not completed at least two (2) years of
service since his or her last hire date (or such lesser period of time as may be determined by the Administrator in its discretion), (ii) customarily works not more than twenty (20) hours per week (or such lesser period of time as may be

dates of the applicable Offering Periods of each such Offering are identical and the provisions of the Plan will separately apply to each Offering. To the extent permitted by U.S. Treasury Regulation Section 1.423-2(a)(1), the terms of each
Offering need not be identical provided that the terms of the Plan and an Offering together satisfy U.S. Treasury Regulation Section 1.423-2(a)(2) and (a)(3).

Exchange Commission declares the Company’s Registration Statement effective and will end on the first Trading Day on or after August 15, 2015, and provided, further, that the second Offering Period under the Plan will commence on the first

 (bb) “Purchase Price” means an amount equal to eighty-five percent (85%) of the Fair Market Value of a share of Common Stock on the Enrollment Date or on the Exercise Date, whichever

subsequent to the first Offering Period will be eligible to participate in the Plan, subject to the requirements of Section 5. 
 (c) Non-U.S. Employees. Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether they also are citizens or residents of the United States or resident aliens
(within the meaning of Section 7701(b)(1)(A) of the Code)) may be excluded from participation in the Plan or an Offering if the participation of such Employees is prohibited under the laws of the applicable jurisdiction or if complying with the
laws of the applicable jurisdiction would cause the Plan or an Offering to violate Section 423 of the Code. 
 (d)
Limitations. Any provisions of the Plan to the contrary notwithstanding, no Eligible Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose
stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company or any Parent or Subsidiary of the Company and/or hold outstanding options to purchase such stock possessing five
percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Parent or Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all
employee stock purchase plans (as defined in Section 423 of the Code) of the Company or any Parent or Subsidiary of the Company accrues at a rate, which exceeds twenty-five thousand dollars ($25,000) worth of stock (determined at the Fair
Market Value of the stock at the time such option is granted) for each calendar year in which such option is outstanding at any time, as determined in accordance with Section 423 of the Code and the regulations thereunder. 

4. Offering Periods. The Plan will be implemented by consecutive Offering Periods with a new Offering Period commencing on the
first Trading Day on or after February 15 and August 15 each year, or on such other date as the Administrator will determine; provided, however, that the first Offering Period under the Plan will commence with the first Trading Day on or
after the date upon which the Company’s Registration Statement is declared effective by the Securities and Exchange Commission and end on the first Trading Day on or after August 15, 2015, and provided, further, that the second Offering
Period under the Plan will commence on the first Trading Day on or after February 15, 2014. The Administrator will have the power to change the duration of Offering Periods (including the commencement dates thereof) with respect to future
Offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter. 
 5. Participation. 
 (a) First Offering Period. An Eligible Employee
will be entitled to continue to participate in the first Offering Period pursuant to Section 3(a) only if such individual submits a subscription agreement authorizing payroll deductions in a form determined by the Administrator to the
Company’s designated plan administrator (i) no earlier than the effective date of the Form S-8 registration statement with respect to the issuance of Common Stock under this Plan and (ii) no later than ten (10) business days
following the effective date of such S-8 registration statement or such other period of time as the 

  
 6 








 
Administrator may determine (the “Enrollment Window”). An Eligible Employee’s failure to submit the subscription agreement during the Enrollment Window will result in the automatic
termination of such individual’s participation in the first Offering Period. 
 (b) Subsequent Offering Periods. An
Eligible Employee may participate in the Plan pursuant to Section 3(b) by (i) submitting to the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to an applicable
Enrollment Date, a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose, or (ii) following an electronic or other enrollment procedure determined by the Administrator.

 6. Contributions. 
 (a) At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have payroll deductions made on each pay day or other Contributions (to the extent permitted by the
Administrator) made during the Offering Period in an amount not exceeding fifteen percent (15%) of the Compensation, which he or she receives on each pay day during the Offering Period; provided, however, that should a pay day occur on an
Exercise Date, a Participant will have any payroll deductions made on such day applied to his or her account under the subsequent Offering Period. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to
contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Offering Period. A Participant’s subscription agreement will remain in effect for
successive Offering Periods unless terminated as provided in Section 10 hereof. 
 (b) Payroll deductions for a Participant
will commence on the first pay day following the Enrollment Date and will end on the last pay day prior to the Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided
in Section 10 hereof; provided, however, that for the first Offering Period, payroll deductions will commence on the first pay day on or following the end of the Enrollment Window. 

(c) All Contributions made for a Participant will be credited to his or her account under the Plan and payroll deductions will be made in
whole percentages only. A Participant may not make any additional payments into such account. 
 (d) A Participant may
discontinue his or her participation in the Plan as provided in Section 10. Unless otherwise determined by the Administrator, during an Offering Period, a Participant may not increase the rate of his or her Contributions and may only decrease
the rate of his or her Contributions once every Purchase Period and such decrease must be to a Contribution rate of a whole number. Any such decrease during a Purchase Period requires the Participant (i) properly completing and submitting to
the Company’s stock administration office (or its designee), on or before a date determined by the Administrator prior to an applicable Exercise Date, a new subscription agreement authorizing the change in Contribution rate in the form provided
by the Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the Administrator. If a Participant has not followed such procedures to change the rate of Contributions, the rate of his or her
Contributions will continue at the originally elected rate throughout the Purchase Period and future Purchase Periods (unless terminated as provided in Section 10). The Administrator may, in its sole 

  
 7 








 
discretion, limit the nature and/or number of Contribution rate changes that may be made by Participants during any Offering Period, and may establish such other conditions or limitations as it
deems appropriate for Plan administration. Any change in payroll deduction rate made pursuant to this Section 6(d) will be effective as of the first full payroll period following five (5) business days after the date on which the change is
made by the Participant (unless the Administrator, in its sole discretion, elects to process a given change in payroll deduction rate more quickly). 
 (e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b), a Participant’s Contributions may be decreased to zero percent (0%)
at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(b) hereof, Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Purchase
Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10. 

(f) Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Eligible Employees to participate in the Plan
via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted under applicable local law, and (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code.

 (g) At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued under the
Plan is disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or any other tax liability payable to any authority
including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock (or any other time
that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company or the Employer to meet applicable
withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Eligible Employee. In addition, the Company
or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or any other method of withholding the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulation
Section 1.423-2(f). 
 7. Grant of Option. On the Enrollment Date of each Offering Period, each Eligible Employee
participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of Common Stock determined by dividing such Eligible
Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be permitted to
purchase during each Offering Period more than one thousand five hundred (1,500) shares of the Company’s Common Stock (subject to any adjustment pursuant to Section 19) and provided further that such purchase will be subject to the
limitations set forth in Sections 3(c) and 13. The Eligible Employee may accept the grant of such option (i) with respect to the first Offering 

  
 8 








 
Period by submitting a properly completed subscription agreement in accordance with the requirements of Section 5 on or before the last day of the Enrollment Window, and (ii) with
respect to any subsequent Offering Period under the Plan, by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute
discretion, the maximum number of shares of Common Stock that an Eligible Employee may purchase during each Offering Period. Exercise of the option will occur as provided in Section 8, unless the Participant has withdrawn pursuant to
Section 10. The option will expire on the last day of the Offering Period. 
 8. Exercise of Option. 

(a) Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of shares of Common
Stock will be exercised automatically on the Exercise Date, and the maximum number of full shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her
account. No fractional shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account, which are not sufficient to purchase a full share will be retained in the Participant’s account for the subsequent
Offering Period, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the Participant. During a Participant’s
lifetime, a Participant’s option to purchase shares hereunder is exercisable only by him or her. 
 (b) If the
Administrator determines that, on a given Exercise Date, the number of shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on
the Enrollment Date of the applicable Offering Period, or (ii) the number of shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will
make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable
among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the shares available for purchase on
such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise
Date, and terminate any or all Offering Periods then in effect pursuant to Section 20. The Company may make a pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding
sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date. 
 9. Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the shares
purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that shares be deposited directly with a broker
designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company 

  
 9 








 
may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such
shares. No Participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the Participant as provided
in this Section 9. 
 10. Withdrawal. 
 (a) A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or her option under the Plan at any time by (i) submitting
to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose, or (ii) following an electronic or other withdrawal procedure determined by the
Administrator. All of the Participant’s Contributions credited to his or her account will be paid to such Participant promptly after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be
automatically terminated, and no further Contributions for the purchase of shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering
Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5. 
 (b) A
Participant’s withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the
termination of the Offering Period from which the Participant withdraws. 
 11. Termination of Employment. Upon a
Participant’s ceasing to be an Eligible Employee, for any reason, he or she will be deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used
to purchase shares of Common Stock under the Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15, and such Participant’s option will be automatically
terminated. 
 12. Interest. No interest will accrue on the Contributions of a participant in the Plan, except as may be
required by applicable law, as determined by the Company, and if so required by the laws of a particular jurisdiction, shall apply to all Participants in the relevant Offering except to the extent otherwise permitted by U.S. Treasury Regulation
Section 1.423-2(f). 
 13. Stock. 
 (a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of shares of Common Stock that will be made available for sale under the
Plan will be four hundred thirty nine thousand four hundred twenty two (439,422) shares of Common Stock, plus an annual increase to be added on the first day of each Fiscal Year beginning with the 2014 Fiscal Year equal to the least of
(i) four hundred thirty nine thousand four hundred twenty two (439,422) shares of Common Stock, (ii) one and one-half percent (1.5%) of the outstanding shares of Common Stock on such date, or (iii) an amount determined by
the Administrator. 

  
 10 









 (b) 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), a Participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist
with respect to such shares. 
 (c) Shares of Common Stock to be delivered to a Participant under the Plan will be registered in
the name of the Participant or in the name of the Participant and his or her spouse. 
 14. Administration. The Plan will
be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms
of the Plan, to designate separate Offerings under the Plan, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for the administration of the Plan (including,
without limitation, to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans may take precedence
over other provisions of this Plan, with the exception of Section 13(a) hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan). Unless otherwise determined
by the Administrator, the Employees eligible to participate in each sub-plan will participate in a separate Offering. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures
regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to
hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local
requirements. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S.
jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to employees resident solely in the U.S. Every finding, decision and determination made by the Administrator will, to the full extent permitted
by law, be final and binding upon all parties. 
 15. Designation of Beneficiary. 

(a) If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any shares of Common Stock
and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In
addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the
option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective. 

  
 11 









 (b) Such designation of beneficiary may be changed by the Participant at any time by notice
in a form determined by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such
shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash
to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 

(c) All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding
Sections 15(a) and (b) above, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f). 

16. Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of
an option or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the
Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

 17. Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate
purpose, and the Company will not be obligated to segregate such Contributions except under Offerings in which applicable local law requires that Contributions to the Plan by Participants be segregated from the Company’s general corporate funds
and/or deposited with an independent third party for Participants in non-U.S. jurisdictions. Until shares of Common Stock are issued, Participants will only have the rights of an unsecured creditor with respect to such shares. 

18. Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to
participating Eligible Employees at least annually, which statements will set forth the amounts of Contributions, the Purchase Price, the number of shares of Common Stock purchased and the remaining cash balance, if any. 

19. Adjustments, Dissolution, Liquidation, Merger or Change in Control. 

(a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other
securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change
in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such


  
 12 









 
manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by
each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13. 
 (b) Dissolution
or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such
proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing
or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date,
unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 
 (c)
Merger or Change in Control. In the event of a merger or Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In
the event that the successor corporation refuses to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period shall end. The New
Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date, that the Exercise Date for the
Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as
provided in Section 10 hereof. 
 20. Amendment or Termination. 

(a) The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any
reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of shares of Common Stock on the next Exercise Date (which may be
sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 19). If the Offering
Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon, except as
otherwise required under local laws, as further set forth in Section 12 hereof) as soon as administratively practicable. 

(b) Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to change the Offering
Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll
withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in 

  
 13 









 
the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts
applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent
with the Plan. 
 (c) In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable
financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to: 

(i) amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards
Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time; 
 (ii)
altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price; 
 (iii) shortening any Offering Period by setting a New Exercise Date, including an Offering Period underway at the time of the Administrator action; 

(iv) reducing the maximum percentage of Compensation a Participant may elect to set aside as Contributions; and 

(v) reducing the maximum number of Shares a Participant may purchase during any Offering Period. 

Such modifications or amendments will not require stockholder approval or the consent of any Plan Participants. 

21. Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be
deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

22. Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of
such option and the issuance and delivery of such shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and
regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance. 

As a condition to the exercise of an option, the Company may require the person exercising such option 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 by any of the
aforementioned applicable provisions of law.

 23. Code Section 409A. The Plan is exempt from the application of Code
Section 409A and any ambiguities herein will be interpreted to so be exempt from Code Section 409A. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an
option granted under the Plan may be subject to Code Section 409A or that any provision in the Plan would cause an option under the Plan to be subject to Code Section 409A, the Administrator may amend the terms of the Plan and/or of an
outstanding option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be
granted under the Plan from or to allow any such options to comply with Code Section 409A, but only to the extent any such amendments or action by the Administrator would not violate Code Section 409A. Notwithstanding the foregoing, the
Company shall have no liability to a Participant or any other party if the option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Code Section 409A is not so exempt or compliant or for any action
taken by the Administrator with respect thereto. The Company makes no representation that the option to purchase Common Stock under the Plan is compliant with Code Section 409A. 

24. Term of Plan. The Plan will become effective upon the earlier to occur of its adoption by the Board or its approval by the
stockholders of the Company. It will continue in effect for a term of twenty (20) years, unless sooner terminated under Section 20. 
 25. Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder
approval will be obtained in the manner and to the degree required under Applicable Laws. 
 26. Governing Law. The Plan
shall be governed by, and construed in accordance with, the laws of the State of California (except its choice-of-law provisions). 
 27. Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity,
illegality or unenforceability shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.
