acts of a majority of the members present at any meeting at which a quorum is present, and, subject to applicable law and the Bylaws of the Company, acts approved in writing by a majority of the Administrator in lieu of a meeting, shall be deemed
the acts of the Administrator. Each member of the Administrator is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company or any Designated Subsidiary,

rights (which need not be identical). 
 (ii) To designate from time to time which Subsidiaries of the Company shall be Designated
Subsidiaries, which designation may be made without the approval of the shareholders of the Company. 
 (iii) To construe and interpret the
Plan and rights granted under it, and to establish, amend and revoke rules and regulations for its administration. The Administrator, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to
the extent it shall deem necessary or expedient to make the Plan fully effective. 
 (iv) To amend the Plan as provided in Article 10.

 (v) Generally, to exercise such powers and to perform such acts as the Administrator deems necessary or expedient to promote the best
interests of the Company and its Subsidiaries and to carry out the intent that the Plan be treated as an “employee stock purchase plan” within the meaning of Section 423 of the Code. 
 3.4 Decisions Binding. The Administrator’s interpretation of the Plan, any rights granted pursuant to the Plan, any participation agreement
and all decisions and determinations by the Administrator with respect to the Plan are final, binding, and conclusive on all parties. 
 ARTICLE IV 
 SHARES SUBJECT TO THE PLAN 
 4.1 Number of Shares. Subject to Article 9, the aggregate number of shares of Stock which may be issued pursuant to rights granted under the Plan shall be 600,000 shares. In addition to the foregoing, subject

increased by that number of shares of Stock equal to the least of (a) 1% of the Company’s outstanding shares on such date, (b) 750,000 shares, or (c) a lesser amount determined by the Board. If any right granted under the Plan

 4.2 Stock Distributed. Any Stock distributed pursuant to the Plan may consist, in whole or in
part, of authorized and unissued Stock, treasury stock or Stock purchased on the open market. 
 ARTICLE V 
 OFFERING PERIODS; OFFERING DOCUMENTS; PURCHASE DATES 
 5.1 Offering Periods. The Administrator may from time to time grant or provide for the grant of rights to purchase Stock of the Company under the Plan to Eligible Employees during one or more periods (each, an
“Offering Period”) selected by the Administrator commencing on such dates (each, an “Enrollment Date”) selected by the Administrator. The terms and conditions applicable to each Offering Period shall
be set forth in an “Offering Document” adopted by the Administrator, which Offering Document shall be in such form and shall contain such terms and conditions as the Administrator shall deem appropriate and shall be
incorporated by reference into and made part of the Plan and shall be attached hereto as part of the Plan. The Administrator shall establish in each Offering Document one or more dates during an Offering Period (the “Purchase
Date(s)”) on which rights granted under the Plan shall be exercised and purchases of Stock carried out during such Offering Period in accordance with such Offering Document and the Plan. The provisions of separate Offering Periods under
the Plan need not be identical. 
 5.2 Offering Documents. Each Offering Document with respect to an Offering Period shall specify
(through incorporation of the provisions of this Plan by reference or otherwise): 
 (i) the length of the Offering Period, which period
shall not exceed twenty-seven months; 
 (ii) the Enrollment Date for such Offering Period; 
 (iii) the Purchase Date(s) during such Offering Period; 
 (iv) the maximum number of shares that may be purchased by any Eligible Employee during such Offering Period, which, in the absence of a contrary designation by the Administrator, shall be 20,000 shares; 

(v) in connection with each Offering Period that contains more than one Purchase Date, the maximum aggregate number of shares which may be purchased
by any Eligible Employee on any given Purchase Date during the Offering Period; and

determines are appropriate, subject to the Plan. 
 ARTICLE VI 
 PARTICIPATION 
 6.1 Eligibility. Any Eligible Employee who shall be
employed by the Company or a Designated Subsidiary on the day immediately preceding a given Enrollment Date for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of this Article
6 and the limitations imposed by Section 423(b) of the Code. 
  

 6 








 6.2 Enrollment in Plan. Except as otherwise set forth in an Offering Document, an Eligible
Employee may become a Participant in the Plan for an Offering Period by delivering a participation agreement to the Company prior to the Enrollment Date for such Offering Period (or such other date specified in the Offering Document), in such form
as the Administrator provides. Each such agreement shall designate a whole percentage of such Eligible Employee’s Compensation to be withheld by the Company or the Designated Subsidiary employing such Eligible Employee on each payday during the
Offering Period as payroll deductions under the Plan. An Eligible Employee may designate any whole percentage of Compensation which is not less than 1% and not more than the maximum percentage specified by the Administrator in the applicable
Offering Document (which percentage shall be 20% in the absence of any such designation) as payroll deductions. The payroll deductions made for each Participant shall be credited to an account for such Participant under the Plan and shall be
deposited with the general funds of the Company. A Participant may change the percentage of Compensation designated in his or her participation agreement, subject to the limits of this Section 6.2, or may suspend his or her payroll deductions,
or may resume payroll deductions pursuant to a new participation agreement, at any time during an Offering Period; provided, however, that the Administrator may limit the number of changes a Participant may make to his or her payroll
deduction elections during each Offering Period and/or Purchase Period in the applicable Offering Document. Any such change, suspension or resumption of payroll deductions shall be effective with the first full payroll period following five business
days after the Company’s receipt of the new participation agreement (or such shorter or longer period as may be specified by the Administrator in the applicable Offering Document). In the event a Participant suspends his or her payroll
deductions, such Participant’s cumulative payroll deductions prior to the suspension shall remain in his or her account and shall not be paid to such Participant unless he or she withdraws from participation in the Plan pursuant to Article 8.
Except as otherwise set forth in an Offering Document, a Participant may participate in the Plan only by means of payroll deduction and may not make contributions by lump sum payment for any Offering Period. 
 6.3 Payroll Deductions. Except as otherwise provided in the applicable Offering Document, payroll deductions for a Participant shall commence on
the first payroll following the Enrollment Date and shall end on the last payroll in the Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Article 9. 
 6.4 Effect of Enrollment. A Participant’s completion of a participation agreement will enroll such Participant in the Plan for each
successive Purchase Period and each subsequent Offering Period on the terms contained therein until the Participant either submits a new participation agreement, withdraws from participation under the Plan as provided in Article 8 or otherwise
becomes ineligible to participate in the Plan. 
 6.5 Limitation on Purchase of Stock. An Eligible Employee may be granted rights
under the Plan only if such rights, together with any other rights granted to such Eligible Employee under “employee stock purchase plans” of the Company, any Parent or any Subsidiary, as specified by Section 423(b)(8) of the Code, do
not permit such employee’s rights to purchase stock of the Company or any Parent or Subsidiary to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined as of the first day of the Offering Period during which such
rights are granted) for each calendar year in which such rights are outstanding at any time. This limitation shall be applied in accordance with Section 423(b)(8) of the Code. 
  

 7 








 6.6 Decrease or Suspension of Payroll Deductions. Notwithstanding the foregoing, to the extent
necessary to comply with Section 423(b)(8) of the Code and Section 6.5 or the other limitations set forth in this Plan, a Participant’s payroll deductions may be suspended by the Administrator at any time during an Offering Period.
The balance of the amount credited to the account of each Participant which has not been applied to the purchase of shares of Stock by reason of Section 423(b)(8) of the Code, Section 6.5 or the other limitations set forth in this Plan
shall be paid to such Participant in one lump sum in cash as soon as reasonably practicable after the Purchase Date. 
 6.7 Foreign
Employees. In order to facilitate participation in the Plan, the Administrator may provide for such special terms applicable to Participants who are citizens or residents of a foreign jurisdiction, or who are employed by a Designated Subsidiary
outside of the United States, as the Administrator may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Such special terms may not be more favorable than the terms of rights granted under the Plan to
Eligible Employees who are residents of the United States. Moreover, the Administrator may approve such supplements to, or amendments, restatements or alternative versions of, this Plan as it may consider necessary or appropriate for such purposes
without thereby affecting the terms of this Plan as in effect for any other purpose. No such special terms, supplements, amendments or restatements shall include any provisions that are inconsistent with the terms of this Plan as then in effect
unless this Plan could have been amended to eliminate such inconsistency without further approval by the shareholders of the Company. 
 ARTICLE VII 
 GRANT AND EXERCISE OF RIGHTS 
 7.1 Grant of Rights. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period shall be granted
a right to purchase the maximum number of shares of Stock specified under Section 5.2(iv), subject to the limits in Section 6.5, and shall have the right to buy, on each Purchase Date during such Offering Period (at the applicable Purchase
Price), such number of shares of the Company’s Stock as is determined by dividing (a) such Participant’s payroll deductions accumulated prior to such Purchase Date and retained in the Participant’s account as of the Purchase
Date, by (b) the applicable Purchase Price. The right shall expire on the last day of the Offering Period. 
 7.2 Exercise of
Rights. On each Purchase Date, each Participant’s accumulated payroll deductions and any other additional payments specifically provided for in the applicable Offering Document will be applied to the purchase of whole shares of Stock of the
Company, up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable Offering Document, at the Purchase Price. No fractional shares shall be issued upon the exercise of rights granted under the Plan, unless the
Offering Document specifically provides otherwise. Any cash in lieu of fractional shares of Stock remaining after the purchase of whole shares of Stock upon exercise of purchase right will be credited to such Participant’s account and carried
forward and applied toward the purchase of whole shares of Stock for the next following Offering Period. Shares issued pursuant to the Plan may be evidenced in such manner as the Committee may determine and may be issued in certificated form or
issued pursuant to book-entry procedures. 
 7.3 Pro Rata Allocation of Shares. If the Administrator determines that, on a given
Purchase Date, the number of shares of Stock with respect to which rights are to be exercised may exceed (i) the number of shares of Stock that were available for issuance under the Plan on the Enrollment Date of the applicable Offering Period,
or (ii) the number of shares of Stock available for issuance under the Plan on such Purchase Date, the Administrator may in its sole discretion provide that the Company shall make a pro rata allocation of the shares of Stock available for
purchase on such Enrollment Date or Purchase 

  

 8 








 
Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants
for whom rights to purchase Stock are to be exercised pursuant to this Article 7 on such Purchase Date, and shall either (x) continue all Offering Periods then in effect, or (y) terminate any or all Offering Periods then in effect pursuant
to Article 10. The Company may make 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 shareholders subsequent to such Enrollment Date. The balance of the amount credited to the account of each Participant which has not been applied to the purchase of shares of Stock shall be paid to such Participant in
one lump sum in cash as soon as reasonably practicable after the Purchase Date. 
 7.4 Withholding. At the time a Participant’s
rights under the Plan are exercised, in whole or in part, or at the time some or all of the 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 right or the disposition of the Stock. At any time, the Company may, but shall 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 sale or early disposition of Stock by the Participant. 
 7.5 Conditions to Issuance of Stock. The Company shall not be required to issue or deliver any certificate or certificates for, or make any book
entries evidencing, shares of Stock upon the exercise of rights under the Plan prior to fulfillment of all of the following conditions: 
 (a)
The admission of such shares to listing on all stock exchanges, if any, on which the Stock is then listed; and 
 (b) The completion of any
registration or other qualification of such shares under any state or federal law or under the rulings or regulations of the Securities and Exchange Commission or any other governmental regulatory body, which the Administrator shall, in its absolute
discretion, deem necessary or advisable; and 
 (c) The obtaining of any approval or other clearance from any state or federal governmental
agency which the Administrator shall, in its absolute discretion, determine to be necessary or advisable; and 
 (d) The payment to the
Company of all amounts which it is required to withhold under federal, state or local law upon exercise of the rights, if any; and 
 (e) The
lapse of such reasonable period of time following the exercise of the rights as the Administrator may from time to time establish for reasons of administrative convenience. 
 ARTICLE VIII 
 WITHDRAWAL; TERMINATION OF EMPLOYMENT OR ELIGIBILITY

 8.1 Withdrawal. A Participant may withdraw all but not less than all of the payroll deductions credited to his or her account
and not yet used to exercise his or her rights under the Plan at any time by giving written notice to the Company in a form acceptable to the Administrator. All of the Participant’s payroll deductions credited to his or her account during the
Offering Period shall be paid to such Participant as soon as reasonably practicable after receipt of notice of withdrawal and such 

  

 9 








 
Participant’s rights for the Offering Period shall be automatically terminated, and no further payroll deductions for the purchase of shares shall be
made for such Offering Period. If a Participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of the next Offering Period unless the Participant delivers to the Company a new participation agreement.

 8.2 Future Participation. A Participant’s withdrawal from an Offering Period shall not have any effect upon his or her
eligibility to participate in any similar plan which may hereafter be adopted by the Company or a Designated Subsidiary or in subsequent Offering Periods which commence after the termination of the Offering Period from which the Participant
withdraws. 
 8.3 Cessation of Eligibility. Upon a Participant’s ceasing to be an Eligible Employee, for any reason, he or she
shall be deemed to have elected to withdraw from the Plan pursuant to this Article 8 and the payroll deductions credited to such Participant’s account during the Offering Period shall be paid to such Participant or, in the case of his or her
death, to the person or persons entitled thereto under 13.4, as soon as reasonably practicable and such Participant’s rights for the Offering Period shall be automatically terminated. 
 ARTICLE IX 
 ADJUSTMENTS UPON CHANGES IN STOCK 
 9.1 Changes in Capitalization. Subject to Section 9.3, in the event of any stock dividend, stock split, combination or exchange of shares,
merger, consolidation, spin-off, recapitalization, distribution of Company assets to shareholders (other than normal cash dividends), or any other corporate event affecting the Stock or the share price of the Stock, the Administrator may make such
proportionate adjustments, if any, as the Administrator in its discretion may deem appropriate to reflect such change with respect to (i) the aggregate number and type of shares of Stock (or other securities or property) that may be issued
under the Plan (including, but not limited to, adjustments of the limitations in Section 3.1 and the limitations established in each Offering Document pursuant to Section 5.2 on the maximum number of shares of Stock that may be purchased);
(ii) the class(es) and number of shares and price per share of Stock subject to outstanding rights; and (iii) the Purchase Price with respect to any outstanding rights. 
 9.2 Other Adjustments. Subject to Section 9.3, in the event of any transaction or event described in Section 9.1 or any unusual or
nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate (including without limitation any Change in Control), or of changes in applicable laws, regulations
or accounting principles, and whenever the Administrator determines that such action is appropriate in order to prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to
any right under the Plan, to facilitate such transactions or events or to give effect to such changes in laws, regulations or principles, the Administrator, in its sole discretion and on such terms and conditions as it deems appropriate, is hereby
authorized to take any one or more of the following actions: 
 (a) To provide for either (i) termination of any outstanding right in
exchange for an amount of cash, if any, equal to the amount that would have been obtained upon the exercise of such right had such right been currently exercisable or (ii) the replacement of such outstanding right with other rights or property
selected by the Administrator in its sole discretion; 
 (b) To provide that the outstanding rights under the Plan be assumed by the
successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar rights covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to
the number and kind of shares and prices; and 
  

 10 








 (d) To make adjustments in the number and type of shares of Stock (or other securities or property)
subject to outstanding rights under the Plan and/or in the terms and conditions of outstanding rights and rights which may be granted in the future; 
 (d) To provide that Participants’ accumulated payroll deductions may be used to purchase Stock prior to the next occurring Purchase Date on such date as the Administrator determines in its sole discretion and the
Participants’ rights under the ongoing Offering Period(s) terminated; and 
 (e) To provide that all outstanding rights shall terminate
without being exercised. 
 9.3 No Adjustment Under Certain Circumstances. No adjustment or action described in this Article 9 or in
any other provision of the Plan shall be authorized to the extent that such adjustment or action would cause the Plan to fail to satisfy the requirements of Section 423 of the Code. 
 9.4 No Other Rights. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or consolidation
of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as
expressly provided in the Plan or pursuant to action of the Administrator under the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by
reason thereof shall be made with respect to, the number of shares of Stock subject to an Award or the grant or exercise price of any Award. 
 ARTICLE X 
 AMENDMENT, MODIFICATION AND TERMINATION 
 10.1 Amendment, Modification and Termination. The Administrator may amend, suspend or terminate the Plan at any time and from time to time;
provided, however, that approval by a vote of the holders of the outstanding shares of the Company’s capital stock entitled to vote shall be required to amend the Plan to: (a) change the aggregate number or type of shares that may
be sold pursuant to rights under the Plan under Section 4.1 (other than any adjustment as provided by Article 9); (b) change the corporations or classes of corporations whose employees may be granted rights under the Plan; or
(c) change the Plan in any manner that would cause the Plan to no longer be an “employee stock purchase plan” within the meaning of Section 423(b) of the Code. 
 10.2 Rights Previously Granted. Except as provided in Article 9 or this Article 10, no termination, amendment or modification may make any change
in any right theretofore granted which adversely affects the rights of any Participant without the consent of such Participant, provided that an Offering Period may be terminated, amended or modified by the Administrator if the Administrator
determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its shareholders. 
 10.3
Certain Changes to Plan. Without shareholder consent and without regard to whether any Participant rights may be considered to have been adversely affected, to the extent permitted by Section 423 of the Code, the Administrator shall 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 

  

 11 








 
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 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. 
 ARTICLE XI 
 TERM OF PLAN 
 The Plan shall be effective on the day prior to the Public Trading Date (the “Effective Date”). The effectiveness of the Plan
shall be subject to approval of the Plan by the shareholders of the Company prior to the Effective Date. No right may be granted under the Plan prior to such shareholder approval. The Plan shall be in effect until the tenth anniversary of the
Effective Date, unless sooner terminated under Article 10. No rights may be granted under the Plan during any period of suspension of the Plan or after termination of the Plan. 
 ARTICLE XII 
 MISCELLANEOUS 
 12.1 Restriction upon Assignment. A right granted under the Plan shall not be transferable other than by will or the laws of descent and
distribution, and is exercisable during the Participant’s lifetime only by the Participant. Except as provided in Section 12.4 hereof, a right under the Plan may not be exercised to any extent except by the Participant. The Company shall
not recognize and shall be under no duty to recognize any assignment or alienation of the Participant’s interest in the Plan, the Participant’s rights under the Plan or any rights thereunder. 
 12.2 Rights as a Shareholder. With respect to shares of Stock subject to a right granted under the Plan, a Participant shall not be deemed
to be a shareholder of the Company, and the Participant shall not have any of the rights or privileges of a shareholder, until such shares have been issued to the Participant or his or her nominee following exercise of the Participant’s rights
under the Plan. No adjustments shall be made for dividends (ordinary or extraordinary, whether in cash, securities, or other property) or distribution or other rights for which the record date occurs prior to the date of such issuance, except as
otherwise expressly provided herein. 
 12.3 Interest. No interest shall accrue on the payroll deductions or lump sum
contributions of a Participant under the Plan. 
 12.4 Designation of Beneficiary. 
 (a) A Participant may, in the manner determined by the Administrator, file a written designation of a beneficiary who is to receive any shares and cash,
if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to a Purchase Date on which the Participant’s rights are exercised but prior to delivery to such Participant of such shares and
cash. In addition, a Participant may file a written 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 Participant’s
rights under the Plan. If the Participant is married and resides in a community property state, a designation of a person other than the Participant’s spouse as his or her beneficiary shall not be effective without the prior written consent of
the Participant’s spouse. 
  

 12 








 (b) Such designation of beneficiary may be changed by the Participant at any time by written notice to
the Company. 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 shall 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. 
 12.5 Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan shall 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. 
 12.6 Equal Rights and Privileges. Subject to Section 6.7, all Eligible Employees of the Company or any Designated Subsidiary will have equal rights and privileges under this Plan so that this Plan
qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code. Subject to Section 6.7, any provision of this Plan that is inconsistent with Section 423 of the Code will, without further act or
amendment by the Company, the Board or the Administrator, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code. 
 12.7 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 shall not be obligated to segregate such payroll
deductions. 
 12.8 Reports. Statements of account shall be given to participating Employees at least annually, which statements shall
set forth the amounts of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any. 
 12.9 No Employment Rights. Nothing in the Plan shall be construed to give any person (including any Eligible Employee or Participant) the right to remain in the employ of the Company or any Parent or Subsidiary or to affect the right
of the Company or any Parent or Subsidiary to terminate the employment of any person (including any Eligible Employee or Participant) at any time, with or without cause. 
 12.10 Notice of Disposition of Shares. Each Participant shall give prompt notice to the Company of any disposition or other transfer of any shares of stock purchased upon exercise of a right under the Plan if
such disposition or transfer is made: (a) within two years from the Enrollment Date of the Offering Period in which the shares were purchased or (b) within one year after the Purchase Date on which such shares were purchased. Such notice
shall specify the date of such disposition or other transfer and the amount realized, in cash, other property, assumption of indebtedness or other consideration, by the Participant in such disposition or other transfer. 
 12.11 Governing Law. The validity and enforceability of this Plan shall be governed by and construed in accordance with the laws of the State of
California without regard to otherwise governing principles of conflicts of law.
