 Exhibit 10.23 
 LIMELIGHT NETWORKS, INC. 
 2013 EMPLOYEE STOCK PURCHASE PLAN

 (as amended June 17, 2013) 
 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 (as defined
in Section 2(j) below). 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) Any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial
owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the Company’s then outstanding voting
securities; 
 (ii) The consummation of the sale or disposition by the Company of all or substantially all of the
Company’s assets; 
 (iii) A change in the composition of the Board occurring within a two (2)-year period, as a result of
which fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” means directors who either (A) are Directors as of the effective date of the Plan, or (B) are elected, or nominated for election, to the
Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but will not include an individual whose election or nomination is in connection with an actual or threatened proxy
contest relating to the election of directors to the Company); or 

 (iv) The consummation of a merger or consolidation of the Company with any other
corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities
of the surviving entity or its parent) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or consolidation.

 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. 
 (e) “Code” means the U.S. Internal Revenue Code of 1986, as amended. Reference to a specific
section of the Code or U.S. Treasury Regulation thereunder will include such section or regulation, any valid regulation or other official applicable guidance promulgated under such section, and any comparable provision of any future legislation or
regulation amending, supplementing or superseding such section or regulation. 
 (f) “Committee” means a
committee of the Board appointed in accordance with Section 14 hereof. 
 (g) “Common Stock” means the
common stock of the Company. 
 (h) “Company” means Limelight Networks, Inc., a Delaware corporation, or any
successor thereto. 
 (i) “Compensation” means an Eligible Employee’s base straight time gross earnings,
exclusive of payments for commissions, overtime and shift premium, incentive compensation, bonuses and other similar compensation. The Administrator, in its discretion, may, on a uniform and nondiscriminatory basis, establish a different definition
of Compensation for a subsequent Offering Period. 
 (j) “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. 
 (k) “Designated Subsidiary” means any Subsidiary that has been designated by the Administrator from time to time in its sole discretion as eligible to participate in the Plan. 

(l) “Director” means a member of the Board. 
 (m) “Eligible Employee” means any individual who is a common law employee of the Company or a Designated Subsidiary and is customarily employed for at least twenty (20) hours per
week and more than five (5) months in any calendar year by the Employer, or any lesser number of hours per week and/or number of months in any calendar year established by the Administrator (if required under applicable local law) for purposes
of any separate Offering. For purposes of the Plan, the employment 

  
 2 

 
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 determined by the Administrator in its discretion), (iii) customarily works not more than five (5) months per calendar year (or such lesser period of time as may be determined by the Administrator
in its discretion), (iv) is a highly compensated employee within the meaning of Section 414(q) of the Code, or (v) is an officer or subject to the disclosure requirements of Section 16(a) of the Exchange Act, provided the
exclusion is applied with respect to each Offering in an identical manner to all highly compensated individuals of the Employer whose Employees are participating in that Offering. Each exclusion shall be applied with respect to an Offering in a
manner complying with U.S. Treasury Regulation Section 1.423-2(e)(2)(ii). Except as required by Applicable Law, any time-based eligibility requirements will be determined as of the Enrollment Date of the
applicable Offering Period.

(p) “Exchange Act” means the Securities Exchange Act of 1934, as amended, including the rules and regulations

Exercise Date under the Plan will be December 2, 2013. 
 (r) “Fair Market Value” means, as of any date
and unless the Administrator determines otherwise, the value of Common Stock determined as follows: 
 (i) If the Common Stock
is listed on any established stock exchange or a national market system, including without limitation the NASDAQ Global Select Market, the NASDAQ Global Market or the NASDAQ Capital Market of The NASDAQ Stock Market, its Fair Market Value will be
the closing sales price for such stock as quoted on such exchange or system on the date of determination (or the closing bid, if no sales were reported), as reported in The Wall Street Journal or such other source as the Administrator deems
reliable; 
 (ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not
reported, its Fair Market Value will be the mean between the high bid and low asked prices for the Common Stock on the date of determination (or if no bids and asks were reported on that date, as applicable, on the last Trading Day such bids and
asks were reported), as reported in The Wall Street Journal or such other source as the Administrator deems reliable; or 

  
 3 

 (iii) In the absence of an established market for the Common Stock, the Fair Market Value
thereof will be determined in good faith by the Administrator. 
 (s) “New Exercise Date” means a new Exercise
Date if the Administrator shortens any Offering Period then in progress. 
 (t) “Offering” means an offer under
the Plan of an option that may be exercised during an Offering Period as further described in Section 4. For purposes of the Plan, the Administrator may designate separate Offerings under the Plan (the terms of which need not be identical) in
which Eligible Employees of one or more Employers will participate, even if the 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). 
 (u) “Offering Periods” means the
periods of approximately six (6) months during which an option granted pursuant to the Plan may be exercised, (i) commencing on the first Trading Day on or after June 1 and December 1 of each year and terminating on the first

stockholders of the Company at the 2013 Annual Meeting of Stockholders, and the first Exercise Date under the Plan will be December 2, 2013, and provided, further, that the second Offering Period under the Plan will commence on December 2,
2013. The duration and timing of Offering Periods may be changed pursuant to Sections 4 and 20.

regulation or stock exchange rule) or pursuant to Section 20.

 3. Eligibility.

 (a) Offering Periods. Any Eligible Employee on a given Enrollment Date will be eligible to participate in the Plan,
subject to the requirements of Section 5. 
 (b) 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.

 (c) 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

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 June 1 and December 1 each year; provided, however, that the first Offering
Period under the Plan will commence on August 15, 2013, subject to the approval of the Plan by the stockholders of the Company at the 2013 Annual Meeting of Stockholders, and the first Exercise Date under the Plan will be December 2, 2013,
and provided, further, that the second Offering Period under the Plan will commence on December 2, 2013. 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 

 5. Participation. An Eligible Employee may participate in the Plan 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 a date determined by the Administrator. 
 (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. If permitted by the Administrator,
as determined in its sole discretion, for an Offering Period, a Participant may increase or decrease the rate of his or her Contributions during the Offering Period by (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 Offering Period and future Offering Periods (unless terminated as provided in Section 10). The Administrator may, in its sole 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). 

  
 6 

 (e) Notwithstanding the foregoing, to the extent necessary to comply with
Section 423(b)(8) of the Code and Section 3(c), a Participant’s Contributions may be decreased to zero percent (0%) at any time during an Offering Period. Subject to Section 423(b)(8) of the Code and Section 3(c) hereof,
Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Offering 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 3,750 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 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. 

  
 7 

 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 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. 

  
 8 

 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 4,000,000 shares of Common Stock. 
 (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. 

  
 9 

 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
Eligible 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. 
 (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). 

  
 10 

 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 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. 

  
 11 

 (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 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; 

  
 12 

 (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. 

  
 13 

 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 until 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 Arizona (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.

other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions that are primarily a private financing transaction for the Company or (B) solely because the level of Ownership held by any
Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares
outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any
additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change

party’s sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of any leave of absence approved by that party, including sick leave, military leave or any other personal leave. Notwithstanding the

The Board may delegate administration of the Plan to a Committee or Committees of one (1) or more members of the Board, and the term “Committee” shall apply to any person or persons to whom such authority has been delegated. If
administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate to a subcommittee any of the administrative
powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be
adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan.

may be issued pursuant to Stock Awards shall not exceed in the aggregate eleven million four hundred sixty-five thousand nine hundred eighty-four (11,465,984) post-reverse split shares of Common Stock less the aggregate number of shares of
Common Stock issued and outstanding and issuable pursuant to outstanding stock options under the 1993 Plan. 

(b) If any Stock Award shall for any reason expire or otherwise terminate, in whole or in part, without having been
exercised in full, or if any shares of Common Stock issued to a Participant pursuant to a Stock Award are forfeited back to or repurchased by the Company because of or in connection with the failure to meet a contingency or condition required to
vest such shares in the Participant, the shares of Common Stock not acquired, such Stock Award or the shares of Common Stock forfeited or repurchased under such Stock Award shall revert to and again become available for issuance under the Plan;
provided, however, that subject to the provisions of Section 11(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued as Incentive Stock Options shall be six million
(6,000,000) post-reverse split shares of Common Stock. 
 (c) Source of Shares. The shares of Common Stock

 7. 

 (ii) A Ten Percent Stockholder shall not be granted a Nonstatutory Stock Option

the date of grant as is permitted by Section 260.140.41 of Title 10 of the California Code of Regulations at the time of the grant of the Option. 
 (iii) A Ten Percent Stockholder shall not be granted a restricted stock award unless the purchase price of the restricted stock is at least (i) one hundred percent (100%) of the Fair

grant of a Stock Award if, at the time of grant, either the offer or the sale of the Company’s securities to such Consultant is not exempt under Rule 701 of the Securities Act (“Rule 701”) because of the nature of the services that
the Consultant is providing to the Company, because the Consultant is not a natural person, or because of some other provision of Rule 701, unless the Company determines that such grant need not comply with the requirements of Rule 701 and will
satisfy another exemption under the Securities Act as well as comply with the securities laws of all other relevant jurisdictions. 
  

	6.	OPTION PROVISIONS. 

 Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock
Options at the time of grant, and, if certificates are issued, a separate certificate or certificates shall be issued for shares of Common Stock purchased on exercise of each type of Option. The provisions of separate Options need not be identical,
but each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: 
 (a) Term. Subject to the provisions of Section 5(b) regarding Ten Percent Stockholders, no Option shall be exercisable after the expiration of ten (10) years from the date it was
granted. 
 (b) Exercise Price of an Incentive Stock Option. Subject to the provisions of Section 5(b)
regarding Ten Percent Stockholders, the exercise price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted.
Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner
satisfying the provisions of Section 424(a) of the Code. 

  
 8. 

 (c) Exercise Price of a Nonstatutory Stock Option. Subject to the provisions
of Section 5(b) regarding Ten Percent Stockholders, the exercise price of each Nonstatutory Stock Option shall be not less than eighty-five percent (85%) of the Fair Market Value of the Common Stock subject to the Option on the date the
Option is granted. Notwithstanding the foregoing, a Nonstatutory Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another
option in a manner satisfying the provisions of Section 424(a) of the Code. 
 (d) Consideration. The
purchase price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (i) in cash at the time the Option is exercised or (ii) at the discretion of the Board at
the time of the grant of the Option (or subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the Company of other Common Stock, (2) according to a deferred payment or other similar arrangement with the Optionholder
or (3) in any other form of legal consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option, the purchase price of Common Stock acquired pursuant to an Option that is paid by delivery to the Company
of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six (6) months (or such longer or shorter period of time required to
avoid a charge to earnings for financial accounting purposes). At any time that the Company is incorporated in Delaware, payment of the Common Stock’s “par value,” as defined in the Delaware General Corporation Law, shall not be made
by deferred payment. 
 In the case of any deferred payment arrangement, interest shall be compounded at least annually and
shall be charged at the minimum rate of interest necessary to avoid (1) the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement and
(2) the treatment of the Option as a variable award for financial accounting purposes. 
 (e) Transferability of an
Incentive Stock Option. An Incentive Stock Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the
foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

 (f) Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock Option shall not be transferable except by
will or by the laws of descent and distribution and, to the extent provided in the Option Agreement, to such further extent as permitted by Section 260.140.41(d) of Title 10 of the California Code of Regulations at the time of the grant of the
Option, and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory Stock Option shall not be transferable except by will or
by the laws of descent and 

  
 9. 

 
distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the
Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option. 

(g) Vesting Generally. The total number of shares of Common Stock subject to an Option may, but need not, vest and therefore
become exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the
Board may deem appropriate. The vesting provisions of individual Options may vary. The provisions of this Section 6(g) are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be
exercised. 
 (h) Minimum Vesting. Notwithstanding the foregoing Section 6(g), to the extent that the
following restrictions on vesting are required by Section 260.140.41(f) of Title 10 of the California Code of Regulations at the time of the grant of the Option, then: 

(i) Options granted to an Employee who is not an Officer, Director or Consultant shall provide for vesting of the total number of
shares of Common Stock at a rate of at least twenty percent (20%) per year over five (5) years from the date the Option was granted, subject to reasonable conditions such as continued employment; and 

(ii) Options granted to Officers, Directors or Consultants may be made fully exercisable, subject to reasonable conditions such as
continued employment, at any time or during any period established by the Company. 
 (i) Termination of Continuous
Service. In the event that an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to
exercise such Option as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or
shorter period specified in the Option Agreement, which period shall not be less than thirty (30) days unless such termination is for cause), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after
termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. 
 (j) Extension of Termination Date. An Optionholder’s Option Agreement may also provide that if the exercise of the Option following the termination of the Optionholder’s Continuous
Service (other than upon the Optionholder’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option shall
terminate on the earlier of (i) the expiration of the term of the Option set forth in Section 6(a) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during
which the exercise of the Option would not be in violation of such registration requirements. 

  
 10.

 (k) Disability of Optionholder. In the event that an Optionholder’s Continuous
Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination), but only within such
period of time ending on the earlier of (i) the date twelve (12) months following such termination (or such longer or shorter period specified in the Option Agreement, which period shall not be less than six (6) months) or
(ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate. 

(l) Death of Optionholder. In the event that (i) an Optionholder’s Continuous Service terminates as a result of the
Optionholder’s death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be
exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated
to exercise the option upon the Optionholder’s death pursuant to Section 6(e) or 6(f), but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death (or such longer or shorter
period specified in the Option Agreement, which period shall not be less than six (6) months) or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the
time specified herein, the Option shall terminate. 
 (m) Early Exercise. The Option may, but need not, include a
provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the
Option. Subject to the “Repurchase Limitation” in Section 10(h), any unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be
appropriate. Provided that the “Repurchase Limitation” in Section 10(h) is not violated, the Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to
avoid a charge to earnings for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option. 

(n) Right of Repurchase. Subject to the “Repurchase Limitation” in Section 10(h), the Option may, but need not,
include a provision whereby the Company may elect to repurchase all or any part of the vested shares of Common Stock acquired by the Optionholder pursuant to the exercise of the Option. Provided that the “Repurchase Limitation” in
Section 10(h) is not violated, the Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have
elapsed following exercise of the Option unless otherwise specifically provided in the Option. 
 (o) Right of First
Refusal. The Option may, but need not, include a provision whereby the Company may elect to exercise a right of first refusal following receipt of notice 

  
 11.

 
from the Optionholder of the intent to transfer all or any part of the shares of Common Stock received upon the exercise of the Option. Except as expressly provided in this Section 6(o)
or in the Stock Award Agreement for the Option, such right of first refusal shall otherwise comply with any applicable provisions of the Bylaws of the Company. The Company will not exercise its right of first refusal until at least six
(6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have elapsed following the exercise of the Option unless otherwise specifically provided in the Option.

  

	7.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

 (a) Stock Bonus Awards. Each stock bonus agreement shall be in such form and shall contain such terms
and conditions as the Board shall deem appropriate. The terms and conditions of stock bonus agreements may change from time to time, and the terms and conditions of separate stock bonus agreements need not be identical, but each stock bonus
agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:  
 (i) Consideration. A stock bonus may be awarded in consideration for past services actually rendered to the Company or an Affiliate for its benefit. 

(ii) Vesting. Subject to the “Repurchase Limitation” in Section 10(h), shares of Common Stock awarded under the

 (iii) Termination of Participant’s Continuous Service. Subject to the “Repurchase Limitation” in Section 10(h), in the event that a Participant’s Continuous Service
terminates, the Company may reacquire any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination under the terms of the stock bonus agreement. Provided that the “Repurchase
Limitation” in Section 10(h) is not violated, the Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting
purposes) have elapsed following receipt of the stock bonus unless otherwise specifically provided in the stock bonus agreement. 
 (iv) Transferability. Rights to acquire shares of Common Stock under the stock bonus agreement shall not be transferable except by will or by the laws of descent and distribution and shall be
exercisable during the lifetime of the Participant only by the Participant. 
 (b) Restricted Stock Awards. Each
restricted stock purchase agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of the restricted stock purchase agreements may change from time to time, and the
terms and conditions of separate restricted stock purchase agreements need not be identical, but each restricted stock purchase agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the
substance of each of the following provisions: 
 (i) Purchase Price. Subject to the provisions of
Section 5(b) regarding Ten Percent Stockholders, the purchase price of restricted stock awards shall not be less than eighty-five percent (85%) of the Common Stock’s Fair Market Value on the date such award is made or at the time the

 12.

 (ii) Consideration. The purchase price of Common Stock acquired pursuant to the
restricted stock purchase agreement shall be paid either: (i) in cash at the time of purchase; (ii) at the discretion of the Board, according to a deferred payment or other similar arrangement with the Participant; or (iii) in any
other form of legal consideration that may be acceptable to the Board in its discretion; provided, however, that at any time that the Company is incorporated in Delaware, then payment of the Common Stock’s “par value,”
as defined in the Delaware General Corporation Law, shall not be made by deferred payment. 
 (iii) Vesting. Subject to
the “Repurchase Limitation” in Section 10(h), shares of Common Stock acquired under the restricted stock purchase agreement may, but need not, be subject to a share repurchase option in favor of the Company in accordance with a
vesting schedule to be determined by the Board. 
 (iv) Termination of Participant’s Continuous Service. Subject to
the “Repurchase Limitation” in Section 10(h), in the event that a Participant’s Continuous Service terminates, the Company may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant
that have not vested as of the date of termination under the terms of the restricted stock purchase agreement. Provided that the “Repurchase Limitation” in Section 10(h) is not violated, the Company will not exercise its repurchase
option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) have elapsed following the purchase of the restricted stock unless otherwise specifically
provided in the restricted stock purchase agreement. 
 (v) Transferability. Rights to acquire shares of Common Stock
under the restricted stock purchase agreement shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Participant only by the Participant. 

 

	8.	COVENANTS OF THE COMPANY. 

(a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of
shares of Common Stock required to satisfy such Stock Awards. 
 (b) Securities Law Compliance. The Company shall
seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided,
however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company
is unable to obtain from any such regulatory commission or agency the authority which counsel for the 

  
 13.

 
Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon
exercise of such Stock Awards unless and until such authority is obtained. 
  

	9.	USE OF PROCEEDS FROM STOCK. 

Proceeds from the sale of Common Stock pursuant to Stock Awards shall constitute general funds of the Company. 

 

	10.	MISCELLANEOUS. 

 (a) Acceleration of Exercisability and Vesting. The Board shall have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any
part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Stock Award stating the time at which it may first be exercised or the time during which it will vest. 

(b) Stockholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect
to, any shares of Common Stock subject to such Stock Award unless and until such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its terms. 

(c) No Employment or other Service Rights. Nothing in the Plan or any instrument executed or Stock Award granted pursuant thereto
shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the
employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or (iii) the service of a Director
pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 

(d) Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of
grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000),
the Options or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of a Stock Award Agreement. 

(e) Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any
Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company
who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and 

  
 14.

 
risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for
the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the
issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular
requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 

(f) Withholding Obligations. To the extent provided by the terms of a Stock Award Agreement, the Participant may satisfy any
federal, state or local tax withholding obligation relating to the exercise or acquisition of Common Stock under a Stock Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the
Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a result
of the exercise or acquisition of Common Stock under the Stock Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lower
amount as may be necessary to avoid variable award accounting); or (iii) delivering to the Company owned and unencumbered shares of Common Stock. 
 (g) Information Obligation. To the extent required by Section 260.140.46 of Title 10 of the California Code of Regulations, the Company shall deliver financial statements to Participants at
least annually. This Section 10(g) shall not apply to key Employees whose duties in connection with the Company assure them access to equivalent information. 
 (h) Repurchase Limitation. The terms of any repurchase option shall be specified in the Stock Award, and the repurchase price may be either the Fair Market Value of the shares of Common Stock on
the date of termination of Continuous Service or the lower of (i) the Fair Market Value of the shares of Common Stock on the date of repurchase or (ii) their original purchase price. To the extent required by Section 260.140.41 and
Section 260.140.42 of Title 10 of the California Code of Regulations at the time a Stock Award is made, any repurchase option contained in a Stock Award granted to a person who is not an Officer, Director or Consultant shall be upon the terms
described below: 
 (i) Fair Market Value. If the repurchase option gives the Company the right to repurchase the
shares of Common Stock upon termination of Continuous Service at not less than the Fair Market Value of the shares of Common Stock to be purchased on the date of termination of Continuous Service, then (i) the right to repurchase shall be
exercised for cash or cancellation of purchase money indebtedness for the shares of Common Stock within ninety (90) 

  
 15.

 
days of termination of Continuous Service (or in the case of shares of Common Stock issued upon exercise of Stock Awards after such date of termination, within ninety (90) days after the
date of the exercise) or such longer period as may be agreed to by the Company and the Participant (for example, for purposes of satisfying the requirements of Section 1202(c)(3) of the Code regarding “qualified small business stock”)
and (ii) the right terminates when the shares of Common Stock become publicly traded. 
 (ii) Original Purchase
Price. If the repurchase option gives the Company the right to repurchase the shares of Common Stock upon termination of Continuous Service at the lower of (i) the Fair Market Value of the shares of Common Stock on the date of repurchase or
(ii) their original purchase price, then (x) the right to repurchase at the original purchase price shall lapse at the rate of at least twenty percent (20%) of the shares of Common Stock per year over five (5) years from the date
the Stock Award is granted (without respect to the date the Stock Award was exercised or became exercisable) and (y) the right to repurchase shall be exercised for cash or cancellation of purchase money indebtedness for the shares of Common
Stock within ninety (90) days of termination of Continuous Service (or in the case of shares of Common Stock issued upon exercise of Options after such date of termination, within ninety (90) days after the date of the exercise) or such
longer period as may be agreed to by the Company and the Participant (for example, for purposes of satisfying the requirements of Section 1202(c)(3) of the Code regarding “qualified small business stock”). 

 

	11.	ADJUSTMENTS UPON CHANGES IN STOCK. 

(a) Capitalization Adjustments. If any change is made in, or other event occurs with respect to, the Common Stock subject to the
Plan or subject to any Stock Award without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company (each a “Capitalization Adjustment”), the Plan will be appropriately adjusted
in the class(es) and maximum number of securities subject to the Plan pursuant to Sections 4(a) and 4(b), and the outstanding Stock Awards will be appropriately adjusted in the class(es) and number of securities and price per share of Common Stock
subject to such outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction
“without receipt of consideration” by the Company.) 
 (b) Dissolution or Liquidation. In the event of a
dissolution or liquidation of the Company, then all outstanding Options shall terminate immediately prior to the completion of such dissolution or liquidation, and shares of Common Stock subject to the Company’s repurchase option may be
repurchased by the Company notwithstanding the fact that the holder of such stock is still in Continuous Service. 

(c) Corporate Transaction. In the event of a Corporate Transaction, any surviving corporation or acquiring corporation may assume
or continue any or all Stock Awards outstanding under the Plan or may substitute similar stock awards for Stock Awards outstanding

under the Plan (it being understood that similar stock awards include, but are not limited to, awards to acquire the same consideration paid to the stockholders or the Company, as the case
may be, pursuant to the Corporate Transaction), and any reacquisition or repurchase rights held by the Company in respect of Common Stock issued pursuant to Stock Awards may be assigned by the Company to the successor of the Company (or such
successor’s parent company), if any, in connection with such Corporate Transaction. In the event that any surviving corporation or acquiring corporation does not assume or continue any or all such outstanding Stock Awards or substitute similar
stock awards for such outstanding Stock Awards, then with respect to Stock Awards that have not been assumed, continued or substituted and that are held by Participants whose Continuous Service has not terminated prior to the effective time of the
Corporate Transaction, the vesting of such Stock Awards (and, if applicable, the time at which such Stock Awards may be exercised) shall (contingent upon the effectiveness of the Corporate Transaction) be accelerated in full to a date prior to the
effective time of such Corporate Transaction as the Board shall determine (or, if the Board shall not determine such a date, to the date that is five (5) days prior to the effective time of the Corporate Transaction), the Stock Awards shall
terminate if not exercised (if applicable) at or prior to such effective time, and any reacquisition or repurchase rights held by the Company with respect to such Stock Awards held by Participants whose Continuous Service has not terminated shall
(contingent upon the effectiveness of the Corporate Transaction) lapse. With respect to any other Stock Awards outstanding under the Plan that have not been assumed, continued or substituted, the vesting of such Stock Awards (and, if applicable, the
time at which such Stock Award may be exercised) shall not be accelerated, unless otherwise provided in a written agreement between the Company or any Affiliate and the holder of such Stock Award, and such Stock Awards shall terminate if not
exercised (if applicable) prior to the effective time of the Corporate Transaction. 
 (d) Change in Control. A
Stock Award held by any Participant whose Continuous Service has not terminated prior to the effective time of a Change in Control may be subject to additional acceleration of vesting and exercisability upon or after such event as may be provided in
the Stock Award Agreement for such Stock Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration shall occur. 

 

	12.	AMENDMENT OF THE PLAN AND STOCK AWARDS.

 (a) Amendment of Plan. The Board at any time, and from time to time, may amend the Plan. However,
except as provided in Section 11(a) relating to Capitalization Adjustments, no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy the requirements of
Section 422 of the Code. 
 (b) Stockholder Approval. The Board, in its sole discretion, may submit any other
amendment to the Plan for stockholder approval. 
 (c) Contemplated Amendments. It is expressly contemplated that
the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive Stock Options granted under it into compliance therewith. 

  
 17.

 (d) No Impairment of Rights. Rights under any Stock Award granted before amendment of
the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 

(e) Amendment of Stock Awards. The Board at any time, and from time to time, may amend the terms of any one or more Stock Awards;
provided, however, that the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing.

  

	13.	TERMINATION OR SUSPENSION OF THE PLAN. 

(a) Plan Term. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on the
day before the tenth (10th) anniversary of the date the Plan is adopted by the Board or approved by the stockholders of the Company, whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is
terminated. 
 (b) No Impairment of Rights. Suspension or termination of the Plan shall not impair rights and
obligations under any Stock Award granted while the Plan is in effect except with the written consent of the Participant. 
  

	14.	EFFECTIVE DATE OF PLAN. 

The Plan shall become effective as determined by the Board, but no Stock Award shall be exercised (or, in the case of a stock bonus, shall
be granted) unless and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board. 

 

	15.	CHOICE OF LAW. 

 The law of the State of California shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such state’s conflict of laws rules.
