 2. Purpose of the Plan. 

The purpose of the Plan is to provide an incentive for present and future employees of the Company and its Participating Subsidiaries to

Code, and that the Plan shall be administered, interpreted and construed in a manner consistent with the requirements of Section 423 of the Code. 

3. Shares Reserved for the Plan. 

The Company shall reserve for issuance and purchase by Participants under the Plan an aggregate of 15,750,000 shares of Common Stock, subject
to adjustment as provided below in Section 13. Shares of Common Stock subject to the Plan may be newly issued shares or treasury shares. If and to the extent that any option to purchase shares of Common Stock shall not be exercised for any
reason, or if such right to purchase shares shall terminate as provided herein, the shares that have not been so purchased hereunder shall again become available for the purposes of the Plan, unless the Plan shall have been terminated. 

4. Administration of the Plan.

Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, to correct any defect or rectify any omission in the Plan, or to reconcile any inconsistency in this Plan and any 

  
 2 







 
option to purchase shares granted hereunder, and to make all other determinations necessary or advisable for the administration of the Plan. The Committee’s actions and determinations with
respect to the foregoing shall be final, conclusive and binding on all persons. The act or determination of a majority of the members of the Committee shall be deemed to be the act or determination of the entire Committee. 

(b) The Committee may, in its discretion, request advice or assistance, or employ such other persons as it deems necessary
or appropriate for the proper administration of the Plan, including, but not limited to employing a brokerage firm, bank or other financial institution to assist in the purchase of shares, delivery of reports or other administrative aspects of the
Plan. 
 5. Eligibility to Participate in the Plan. 

Subject to limitations imposed by Section 423(b) of the Code, each Eligible Employee who is employed by the Company or a Participating
Subsidiary for 30 days prior to an Enrollment Date shall be eligible to participate in the Plan for the Offering Period beginning on that Enrollment Date. 

6. Election to Participate in the Plan. 

(a) Each Eligible Employee may elect to participate in the Plan by completing an enrollment agreement in the form
provided by the Company and filing such enrollment agreement with the Company prior to the applicable Enrollment Date, unless the Committee establishes another deadline for filing the enrollment agreement with respect to a given Offering Period.

 (b) Unless a Participant withdraws from participation in the Plan as provided in Section 10 or authorizes a
different payroll deduction by filing a new enrollment agreement prior to the Enrollment Date of a succeeding Offering Period, a Participant who is participating in an Offering Period as of the Exercise Date of such Offering Period shall be deemed
to have (i) elected to participate in the immediately succeeding Offering Period and (ii) authorized the same payroll deduction percentage for such immediately succeeding Offering Period as was in effect for such Participant immediately
prior to such succeeding Offering Period. 
 7. Payroll Deductions. 

(a) All Participant contributions to the Plan shall be made only by payroll deductions. Each time a Participant files the
enrollment agreement with respect to an Offering Period, the Participant shall authorize payroll deductions to be made during the Offering Period in an amount from 1% to 10% (in whole percentages) of the Eligible Compensation that the Participant
receives on each payroll date during such Offering Period. Payroll deductions for a Participant shall commence on the first payroll date following the Enrollment Date and shall end on the last payroll date in the Offering Period to which such
authorization is applicable, unless sooner terminated by the Participant as provided below in Section 10. 

(b) All payroll deductions made for a Participant shall be deposited in the Company’s general corporate account and
shall be credited to the Participant’s account under the Plan. No interest shall accrue on or be credited with respect to the payroll deductions of a Participant under the Plan. A Participant may not make any additional contributions into such
account. 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. 

(c) Except as provided in Section 10, a Participant may not change his contribution election during an Offering
Period.

 (d) Notwithstanding the foregoing provisions of this Section 7, no
Participant may make payroll deductions during any calendar year in excess of $21,250, or such other limit as may be established by the Committee, in its discretion. 

8. Grant of Options. 

(a) On the Enrollment Date of each Offering Period, subject to the limitations set forth in Sections 3 and 8(b) hereof,
each Eligible Employee shall be granted an option to purchase on the Exercise Date for such Offering Period a number of whole and fractional shares of the Company’s Common Stock determined by dividing such Eligible Employee’s payroll
deductions accumulated during the Offering Period by the Exercise Price established for such Offering Period. 

(b) Notwithstanding any provision of the Plan to the contrary, no Eligible Employee shall be granted an option under the
Plan (i) if, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own stock and/or hold outstanding options to purchase
stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any Subsidiary of the Company, or (ii) which permits such Eligible Employee’s rights to purchase stock under all employee
stock purchase plans of the Company and its Subsidiaries to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any
time. 
 9. Automatic Purchase. 

Unless a Participant withdraws from the Plan as provided below in Section 10, the Participant’s option for the purchase of shares
will be exercised automatically on each Exercise Date for which an enrollment agreement has been filed, and the maximum number of whole and fractional shares subject to the option will be purchased for the Participant at the Exercise Price
established for that Offering Period, as provided above in Section 8. 
 10. Withdrawal; Termination of Employment.

 (a) A Participant may withdraw all of the payroll deductions credited to the Participant’s account for a
given Offering Period by providing written notice to the Company no later than 45 days prior to the last day of such Offering Period. A Participant shall not be permitted to make a partial withdrawal of the payroll deductions credited to his
account. All of the Participant’s payroll deductions credited to the Participant’s account will be paid to him promptly after receipt of the Participant’s notice of withdrawal, the Participant’s participation in the Plan will be
automatically terminated, and no further payroll deductions for the purchase of shares hereunder will be made. Payroll deductions will not resume on behalf of a Participant who has withdrawn from the Plan, unless written notice is delivered to the
Company within the enrollment period preceding the commencement of a new Offering Period directing the Company to resume payroll deductions. 

(b) Upon termination of the Participant’s Continuous Employment prior to the Exercise Date of the Offering Period for
any reason, including retirement or death, the payroll deductions credited to the Participant’s account will be returned to the Participant or, in the case of death, to the Participant’s estate, and the Participant’s options to
purchase shares under the Plan will be automatically terminated. 
 (c) In the event a Participant ceases to be an
Eligible Employee during an Offering Period, the Participant will be deemed to have elected to withdraw all payroll deductions credited to his account from the Plan. In such circumstance, the payroll deductions credited to the Participant’s
account will be returned to the Participant, and the Participant’s options to purchase shares under the Plan will be terminated.

 11. Transferability. 

Options to purchase Common Stock granted under the Plan are not transferable, in any manner, by a Participant and are exercisable only by the
Participant. 
 12. Reports. 

Individual accounts will be maintained for each Participant in the Plan. Following each Exercise Date, statements of account will be given to
Participants who have purchased shares under Section 9. Such statements will set forth the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any. 

13. Adjustments Upon Changes in Capitalization. 

(a) If the outstanding shares of Common Stock are increased or decreased, or are changed into or are exchanged for a
different number or kind of shares, as a result of one or more reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends or the like, upon authorization of the Committee, appropriate
adjustments shall be made in the number and/or kind of shares, and the per share purchase price thereof, which may be issued in the aggregate and to any Participant upon exercise of options granted under the Plan. 

(b) In the event of the proposed dissolution or liquidation of the Company, each Offering Period will terminate
immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another
corporation, each option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Committee determines, in the exercise of its sole
discretion and in lieu of such assumption or substitution, that the Participant shall have the right to exercise the option as to all of the optioned stock, including shares as to which the option would not otherwise be exercisable. If the Committee
makes an option fully exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Committee shall notify the Participant that the option shall be fully exercisable for a stated period, which shall not be less
than 10 days from the date of such notice, and the option will terminate upon the expiration of such period. 
 (c) In
all cases, the Committee shall have full discretion to exercise any of the powers and authority provided under this Section 13, and the Committee’s actions hereunder shall be final and binding on all Participants. No fractional shares of
stock shall be issued under the Plan pursuant to any adjustment authorized under the provisions of this Section 13. 

14. Amendment of the Plan. 

The Board may at any time, or from time to time, amend the Plan in any respect; provided, however, that the Plan may not be amended in any way
that will cause rights issued under the Plan to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Code or any successor thereto, including, without limitation, shareholder approval, if required.

 15. Termination of the Plan. 

The Plan and all rights of Eligible Employees hereunder shall terminate: 

(a) on the Exercise Date that Participants become entitled to purchase a number of shares greater than the number of
reserved shares remaining available for purchase under the Plan; or 
 (b) at any time, at the discretion of the Board.


  
 5 







 In the event that the Plan terminates under circumstances described in Section 15(a) above,
reserved shares remaining as of the termination date shall be sold to Participants on a pro rata basis. 
 16. 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. 

17. Shareholder Approval. 

The Plan shall be subject to approval by the shareholders of the Company within twelve months after the date the Plan is adopted by the Board
of Directors. If such shareholder approval is not obtained prior to the first Exercise Date, the Plan shall be null and void and all Participants shall be deemed to have withdrawn all payroll deductions credited to their accounts on such Exercise
Date pursuant to Section 10. 
 18. Conditions Upon Issuance of Shares. 

(a) The Plan, the grant and exercise of options to purchase shares of Common Stock under the Plan, and the Company’s
obligation to sell and deliver shares upon the exercise of options to purchase shares shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may,
in the opinion of counsel for the Company, be required. Notwithstanding anything in the Plan to the contrary, share certificates shall not be delivered to Participants until the later of (i) the date on which the applicable holding period to
avoid a disqualifying disposition (within the meaning of Code Section 421) expires, or (ii) the date that a Participant specifically requests a certificate for shares purchased pursuant to the Plan. 

(b) The Company may make such provisions, as it deems appropriate, for withholding by the Company pursuant to all
applicable tax laws of such amounts as the Company determines it is required to withhold in connection with the purchase or sale by a Participant of any Common Stock acquired pursuant to the Plan. The Company may require a Participant to satisfy any
relevant tax requirements before authorizing any issuance of Common Stock to such Participant.
