a manner that is consistent with the requirements of that section of the Code.

 (ii) The consummation of the sale or disposition by the Company of all or substantially all of the Company’s assets;

Journal or such other source as the Administrator deems reliable, or;

 (a) Any individual who is an Employee as of the Enrollment Date of any Offering Period will be eligible to participate in such Offering
Period, subject to the requirements of Section 5. 
 (b) Limitations. Any provisions of the Plan to the contrary
notwithstanding, no Employee will be granted an option under the Plan (i) to the extent that, immediately after the grant, such Employee (or any other person whose stock would be attributed to such 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

which such option is outstanding at any time. 
 4. Offering Periods. The Plan will be implemented by consecutive, overlapping
Offering Periods with a new Offering Period commencing on the first Trading Day on or after June 15 and December 15 of each year, or on such other date as the Administrator will determine, and continuing thereafter until terminated in
accordance with Section 20; provided, however, that the first Offering Period under the Plan will commence with the first Trading Day on or after the date, if any, on which the Administrator determines it is appropriate to implement the Plan
and ending on the first Trading Day on or after a date specified by the Administrator. 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. An Employee who is eligible to participate in the Plan pursuant to Section 3(b) may become a participant by (i) submitting to the Company’s payroll office (or its designee), on or before a date
prescribed by the Administrator prior to an applicable Enrollment Date, a properly completed subscription agreement authorizing payroll deductions in the form provided by the Administrator for such purpose, or (ii) following an electronic or
other enrollment procedure prescribed by the Administrator. 
  

 -3- 








 6. Payroll Deductions. 
 (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
payday during the Offering Period in an amount not exceeding 15% of the Compensation which he or she receives on each such payday. 
 (b) Payroll deductions authorized by a participant will commence on the first payday following the Enrollment Date and will end on the last payday in the Offering Period to which such authorization is applicable, unless sooner terminated by
the participant as provided in Section 10. 
 (c) All payroll deductions made for a participant will be credited to his
or her account under the Plan and will be withheld 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, or may change the rate of his or her payroll deductions during the Offering Period by (i) properly completing
and submitting to the Company’s payroll office (or its designee), on or before a date prescribed by the Administrator prior to an applicable Exercise Date, a new subscription agreement authorizing the change in payroll deduction rate in the
form provided by the Administrator for such purpose, or (ii) following an electronic or other procedure prescribed by the Administrator; provided, however, that a participant may only make one payroll deduction change during each Purchase
Period. If a participant has not followed such procedures to change the rate of payroll deductions, the rate of his or her payroll deductions 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 payroll deduction rate changes that may be made by participants during any Offering Period. 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(c), a participant’s payroll deductions may be decreased to zero percent (0%) at any time during a Purchase Period. Payroll deductions will recommence at
the rate originally elected by the participant effective as of the beginning of the first Purchase Period which is scheduled to end in the following calendar year, unless terminated by the participant as provided in Section 10. 
 (f) At the time the option is exercised, in whole or in part, or at the time some or all of the Company’s Common Stock issued under
the Plan is disposed of, the participant must make adequate provision for the Company’s federal, state, or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock. At any
time, the Company may, but will not be obligated to, withhold from the participant’s compensation the amount necessary for the Company to meet applicable withholding obligations, including any withholding required to make available to the
Company any tax deductions or benefits attributable to the sale or early disposition of Common Stock by the Employee. 
 7. Grant of
Option. On the Enrollment Date of each Offering Period, each 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 participant’s payroll deductions accumulated prior to such Exercise Date and retained in the participant’s account as of the Exercise Date by the applicable 

  

 -4- 








 
Purchase Price; provided that in no event will a participant be permitted to purchase during each Purchase Period more than 5,000 shares of 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 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 a participant may purchase during
each Purchase Period of such 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 option will be purchased for such participant at the applicable Purchase Price with the accumulated payroll deductions in his or her account. No fractional shares of Common Stock will be purchased; any payroll
deductions 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 Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10. Any other monies 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) Notwithstanding any contrary Plan provision, 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 (A) 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 (B) 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 terminate any or all Offering Periods then in effect pursuant to Section 20. The Company may make pro rata allocation of the shares of Common Stock available on the Enrollment Date of any applicable Offering Period
pursuant to the preceding sentence, notwithstanding any authorization of additional shares of Common Stock for issuance under the Plan by the Company’s shareholders subsequent to such Enrollment Date. 
 9. Delivery. As soon as administratively practicable after each Exercise Date on which a purchase of shares of Common Stock occurs, the Company
will arrange the delivery to each participant, as appropriate, 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. No
participant will have any voting, dividend, or other shareholder 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. 
  

 -5- 








 10. Withdrawal. 
 (a) Under procedures established by the Administrator, a participant may withdraw all but not less than all the payroll deductions
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 payroll office (or its designee) a written notice of withdrawal in the form prescribed by the
Administrator for such purpose, or (ii) following an electronic or other withdrawal procedure prescribed by the Administrator. All of the participant’s payroll deductions credited to his or her account will be paid to such participant as
promptly as practicable after the effective date of his or her withdrawal and such participant’s option for the Offering Period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made for such
Offering Period. If a participant withdraws from an Offering Period, payroll deductions 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 which may hereafter be adopted by the Company or in succeeding Offering Periods which 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 Employee, for any reason, he or she will be deemed to have elected to
withdraw from the Plan and the payroll deductions 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. The preceding sentence notwithstanding, a participant who receives payment in lieu of notice of
termination of employment will be treated as continuing to be an Employee for the participant’s customary number of hours per week of employment during the period in which the participant is subject to such payment in lieu of notice.

 12. Interest. No interest will accrue on the payroll deductions of a participant in the Plan. 
 13. Stock. 
 (a)
Subject to adjustment upon changes in capitalization of the Company as provided in Section 19, the maximum number of shares of Common Stock which will be made available for sale under the Plan will be 5,000,000 shares of Common Stock plus an
annual increase to be added on the first day of the Company’s fiscal year beginning with the fiscal year after the first Offering Period, equal to the lesser of (i) the number of shares necessary to restore the reserve to 5,000,000 shares
of Common Stock, or (ii) an amount determined by the Board. 
 (b) 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 Executive Committee of the Board or a committee of members of the Board who will be appointed from time to time by, and will serve at the pleasure of, the Board, will administer the Plan. The Administrator will have full
and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility, to adjudicate all disputed claims filed under the Plan and to establish such procedures that it deems necessary for
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 United States).
The Administrator, in its sole discretion and on such terms and conditions as it may provide, may delegate to one or more individuals all or any part of its authority and powers under the Plan. Every finding, decision and determination made by the
Administrator (or its designee) will, to the full extent permitted by law, be final and binding upon all parties. 
  

 -6- 








 15. Designation of Beneficiary. 
 (a) A participant may designate 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, a participant may designate 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. 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 under this Section 15 will be made in such form and manner as the Administrator may prescribe from
time to time. 
 16. Transferability. Neither payroll deductions 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)
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 from an Offering Period in accordance with Section 10.

 17. Use of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any
corporate purpose, and the Company will not be obligated to segregate such payroll deductions. Until shares of Common Stock are issued under the Plan (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. 
 18. Reports.
Individual accounts will be maintained for each participant in the Plan. Statements of account will be given to participating Employees at least annually, which statements will set forth the amounts of payroll deductions, the Purchase Price, the
number of shares of Common Stock purchased and the remaining cash balance, if any. 
 19. Adjustments, Dissolution, Liquidation or Change
of 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 such that an adjustment is determined by the Administrator (in its sole discretion) to be appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan, then the Administrator will, in such manner as it may deem equitable, adjust the number and class of Common Stock which 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 which has not yet been exercised, and the numerical limits of Sections 7 and 13. 
  


 -7- 








 (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Offering Period then in progress will be shortened by setting a new Exercise Date (the “Dissolution Exercise Date”), and will terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The Dissolution Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Board will notify each participant in writing, at least ten
(10) business days prior to the Dissolution Exercise Date, that the Exercise Date for the participant’s option has been changed to the Dissolution Exercise Date and that the participant’s option will be exercised automatically on the
Dissolution Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10. 
 (c) Change of Control. In the event of a Change of 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, any Purchase Periods then in progress will be shortened by setting a new Exercise Date (the “New Exercise Date”) and any
Offering Periods then in progress will end on the New Exercise Date. The New Exercise Date will be before the date of the Company’s proposed Change of Control. The Board will notify each participant in writing, at least ten (10) business
days 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. 
 20. Amendment or Termination.

 (a) The Administrator may at any time and for any reason terminate or amend the Plan. Except as provided in
Section 19, no such termination can affect options previously granted under the Plan, provided that an Offering Period may be terminated by the Administrator on any Exercise Date if the Administrator determines that the termination or
suspension of the Plan is in the best interests of the Company and its stockholders. Except as provided in Section 19 and this Section 20, no amendment may make any change in any option theretofore granted which adversely affects the
rights of any participant. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation or stock exchange rule), the Company will obtain stockholder approval in such
a manner and to such a degree as required. 
 (b) Without stockholder consent and without regard to whether any participant
rights may be considered to have been “adversely affected,” the Administrator will be entitled to change the Offering Periods, 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
amounts withheld from the participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with the Plan. 
  

 -8- 








 (c) In the event the Administrator determines that the ongoing operation of the Plan may
result in unfavorable financial accounting consequences, the Board may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to:

 (i) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in
Purchase Price; 
 (ii) shortening any Offering Period so that Offering Period ends on a new Exercise Date, including an
Offering Period underway at the time of the Board action; and 
 (iii) allocating shares. 
 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 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 under the Plan 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, including the rules and regulations promulgated thereunder, the Exchange Act 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. 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. 
 24. Automatic
Transfer to Low Price Offering Period. To the extent permitted by any applicable laws, regulations, or stock exchange rules if the Fair Market Value of the Common Stock on any Exercise Date in an Offering Period is lower than the Fair Market
Value of the Common Stock on the Enrollment Date of such Offering Period, then all participants in such Offering Period will be automatically withdrawn from such Offering Period immediately after the exercise of their option on such Exercise Date
and automatically re-enrolled in the immediately following Offering Period.
