Document

The Plan includes two components: a Code Section 423 Component (the “423 Component”) and a non-Code Section 423 Component (the “Non-423 Component”). It is intended for the 423 Component to constitute an “employee stock purchase plan” within the meaning of Section 423(b) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the 423 Component shall be interpreted in accordance with that intent (although the Company makes no undertaking or representation to maintain such qualification). In addition, this Plan authorizes the grant of Options (as defined in Section 8) under the Non-423 Component, which does not qualify as an “employee stock purchase plan” under Section 423 of the Code, and such Options granted under the Non-423 Component shall be granted pursuant to separate Offerings (as defined in Section 2) containing such sub-plans, appendices, rules or procedures as may be adopted by the Administrator (as defined in Section 1) and designed to achieve tax, securities laws or other objectives for eligible employees and the Designated Companies in locations outside of the United States (as further described in Section 13). Except as otherwise provided herein or by the Administrator, the Non-423 Component will operate and be administered in the same manner as the 423 Component.

For purposes of this Plan, the Administrator may designate separate Offerings under the Plan, the terms of which need not be identical, in which eligible employees will participate, even if the dates of the applicable Offerings are identical, provided that the terms of participation are the same within each separate Offering under the 423 Component as determined under Section 423 of the Code. Solely by way of example and without limiting the foregoing, the Company could, but is not required to, provide for simultaneous Offerings under the Section 423 Component and the Non-423 Component of the Plan.

1. Administration. The Plan will be administered by the person or persons (the “Administrator”) appointed by the Company’s Board of Directors (the “Board”) for such purpose. The Administrator has authority at any time to: (i) adopt, alter and repeal such rules, guidelines and practices for the administration of the Plan and for its own acts and proceedings as it deems advisable; (ii) interpret the terms and provisions of the Plan; (iii) determine when and how Options will be granted and the provisions and terms of each Offering and/or Purchase Period (as defined in Section 11) (which need not be identical); (iv) select Designated Companies; (v) impose a mandatory holding period pursuant to which Participants (as defined in Section 11) may not dispose of or transfer shares of Stock purchased under the Plan for a period of time determined by the Administrator in its discretion; (vi) make all determinations it deems advisable for the administration of the Plan; (vii) decide all disputes arising in connection with the Plan; and (viii) otherwise supervise the administration of the Plan. Further, the Administrator may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures, provided that the adoption and implementation of any such rules and/or procedures would not cause the 423 Component to be in noncompliance with Section 423 of the Code. Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding handling of participation elections, payroll deductions, payment of interest, conversion of local currency, payroll tax, withholding procedures and handling of share certificates that vary with local requirements. All interpretations and decisions of the Administrator are binding on all persons, including the Company and the Participants. No member of the Board or

2. Offerings. The Company may make one or more offerings to eligible employees to purchase shares of Stock under the Plan (“Offerings”), consisting of one or more Purchase Periods. Each Offering will begin and end on the dates determined by the Administrator, provided that no Offering shall exceed 27 months in duration. Unless the Administrator, in its sole discretion, determines otherwise prior to an Offering Date (as defined in Section 3), and to the extent an Offering has more than one Purchase Period and to the extent permitted by applicable law, if the Fair Market Value of the Stock on any Exercise Date in an Offering is lower than the Fair Market Value of the Stock on the Offering Date, then all participants in such Offering will automatically be withdrawn from such Offering immediately after the exercise of their Options on such Exercise Date and automatically re-enrolled in the immediately following Offering as of the first day thereof and the preceding Offering will terminate.

3. Eligibility. All individuals classified as employees on the payroll records of the Company or a Designated Company as of the first day of the applicable Offering (the “Offering Date”) are eligible to participate in such Offering under the Plan, provided that the Administrator may determine, in advance of any Offering, that employees are eligible only if, as of the Offering Date, (a) they are customarily employed by the Company or a Designated Company for more than (i) 20 hours a week or (ii) five months per calendar year, (b) they have completed such minimum period of service prior to the Offering Date as determined by the Administrator (provided such service requirement does not exceed two years of employment, and/or (c) they are not highly compensated employees (within the meaning of Section 414(q) of the Code). Notwithstanding any other provision herein, individuals who are not contemporaneously classified as employees of the Company or a Designated Company for purposes of the Company’s or applicable Designated Company’s payroll system are not considered to be eligible employees of the Company or any Designated Company and are not eligible to participate in the Plan. In the event any such individuals are reclassified as employees of the Company or a Designated Company for any purpose, including, without limitation, common law or statutory employees, by any action of any third party, including, without limitation, any government agency, or as a result of any private lawsuit, action or administrative proceeding, such individuals shall, notwithstanding such reclassification, remain ineligible for participation. Notwithstanding the foregoing, the exclusive means for individuals who are not contemporaneously classified as employees of the Company or a Designated Company on the Company’s or Designated Company’s payroll system to become eligible to participate in this Plan is through an amendment or sub-plan to this Plan, duly executed by the Company, that specifically renders such individuals eligible to participate herein.

4. Participation. An eligible employee who is not a Participant in any prior Offering may participate in a subsequent Offering by submitting an enrollment or other form to the Company or an agent designated by the Company or by completing an online enrollment process in a manner determined by the Administrator (including, but not limited to, by electronic means) by the deadline established by the Administrator for the Offering. The enrollment or other form or online enrollment will (a) state a whole percentage (unless the Administrator determines in advance of an Offering to require that a fixed amount be specified in lieu of a percentage) to be contributed from an eligible employee’s Compensation (as defined in Section 11) per pay period and (b) authorize the purchase of shares of Stock in each Offering in accordance with the terms of the Plan. An employee who does not enroll in accordance with these procedures will be deemed to have waived the right to participate. Unless a Participant files a new enrollment form, withdraws from the Plan or otherwise becomes ineligible to participate in the Plan, such Participant’s payroll deductions and purchases will continue at the same percentage of Compensation for

5. Employee Contributions. Each eligible employee may authorize payroll deductions at a minimum of 0% up to a maximum of 15% of such employee’s Compensation for each pay period or such other minimum or maximum as may be specified by the Administrator in advance of an Offering. The Company will maintain book accounts showing the amount of payroll deductions made by each Participant for each Purchase Period within an Offering. No interest will accrue or be paid on payroll deductions, unless required under applicable law.

Notwithstanding any other provisions of the Plan to the contrary, in non-U.S. jurisdictions where participation in the Plan through payroll deductions is prohibited or otherwise problematic under applicable law (as determined by the Administrator in its sole discretion), the Administrator may provide that an eligible employee may elect to participate through other contributions in a form acceptable to the Administrator in lieu of or in addition to payroll deductions; provided, however, that, for any Offering under the 423 Component, any alternative method of contribution must be applied on an equal and uniform basis to all eligible employees in the Offering. Any reference to “payroll deductions” in this Section 5 (or in any other section of the Plan) will similarly cover contributions by other means made pursuant to this Section 5.

6. Contribution Changes. Unless otherwise determined by the Administrator, except in the case of withdrawal as described in Section 7, a Participant may increase or decrease such Participant’s payroll deductions no more than two times during any Offering and may increase or decrease such Participant’s payroll deductions with respect to the next Offering (subject to the limitations of Section 5) by filing a new enrollment form by the deadline established by the Administrator for the Offering. The Administrator may, in advance of any Offering, establish alternative rules permitting a Participant to increase, decrease or terminate such Participant’s payroll deductions during an Offering.

7. Withdrawal. A Participant may withdraw from participation in the Plan by giving written notice to the Company or an agent designated by the Company in a form acceptable to the Administrator (including, but not limited to, by electronic means) no later than two weeks prior to the end of the then-applicable Offering (or such shorter or longer period as may be specified by the Administrator prior to any Offering). The Participant’s withdrawal will be effective as soon as practicable following receipt of written notice of withdrawal by the Company or an agent designated by the Company. Following a Participant’s withdrawal, the Company will promptly refund such Participant’s entire account balance under the Plan to such Participant (after payment for any shares of Stock purchased before the effective date of withdrawal). Partial withdrawals are not permitted. A Participant may not begin participation again in any Offering from which such Participant has withdrawn, but may enroll in a subsequent Offering in accordance with Section 4.

8. Grant of Options. On each Offering Date, the Company will grant to each eligible employee who is then a Participant in the Plan an option (“Option”) to purchase on the last day of a Purchase Period (an “Exercise Date”) the lowest of (a) a number of shares of Stock determined by dividing such Participant’s accumulated payroll deductions on such Exercise Date by the Option Price (as defined below), (b) the number of shares of Stock determined by dividing $25,000 by the Fair Market Value of the Stock on the Offering Date for such Offering or (c) such other number of shares of Stock determined by the Administrator in advance of the Offering; provided, however, that such Option shall be subject to the limitations set forth below. Each Participant’s Option shall be exercisable only to the extent of such Participant’s accumulated payroll deductions on the Exercise Date. The purchase price for each

Notwithstanding the foregoing, no Participant may be granted an Option hereunder if such Participant, immediately after the Option was granted, would be treated as owning stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or any Parent or Subsidiary (each as defined in Section 11). For purposes of the preceding sentence, the attribution rules of Section 424(d) of the Code will apply in determining the stock ownership of a Participant, and all stock that the Participant has a contractual right to purchase will be treated as stock owned by the Participant. In addition, no Participant may be granted an Option that permits such Participant rights to purchase Stock under the Plan, and any other employee stock purchase plan of the Company and its Parents and Subsidiaries, to accrue at a rate that exceeds $25,000 of the fair market value of such stock (determined on the Option grant date or dates) for each calendar year in which the Option is outstanding at any time. The purpose of the limitation in the preceding sentence is to comply with Section 423(b)(8) of the Code and shall be applied taking Options into account in the order in which they were granted.

9. Exercise of Option and Purchase of Shares. Each employee who continues to be a Participant in the Plan on the Exercise Date shall be deemed to have exercised such Participant’s Option on such date and shall acquire from the Company such number of whole shares of Stock as such Participant’s accumulated payroll deductions on such date will purchase at the Option Price, subject to any other limitations contained in the Plan; provided, however, in order to purchase shares on any Exercise Date, the employee must have a valid and active account at a broker designated by the Company or a designated agent of the Company for the duration of the Offering in which such Exercise Date occurs. Unless otherwise determined by the Administrator in advance of any Offering, any balance remaining in a Participant’s account at the end of a Purchase Period or Offering will be promptly refunded to the Participant.

“Compensation” means the amount of money reportable on a Participant’s Form W-2 before any withholdings for health insurance or under a Section 401(k), 125, 129 or similar plan, excluding third party sick or disability pay, allowances and reimbursements for expenses such as relocation allowances or travel expenses, whether specifically designated as such or designated as signing bonuses, income or gains attributable to restricted stock, restricted stock units, stock options, stock appreciation rights or other similar equity based compensation, imputed income for non-cash items, such as life insurance premiums, and similar items, whether or not specifically itemized on the Form W-2. For avoidance of doubt, “Compensation” shall include cash payments in respect of bonuses, commissions and other cash-based incentive plans. The Administrator shall have the discretion to determine the application of this definition to Participants outside of the United States.

“Designated Company” means each Affiliate and Subsidiary that has been designated by the Administrator from time to time, in its sole discretion, as eligible to participate in the Plan, such designation to specify whether such participation is in the 423 Component or Non-423 Component. A Designated Company may participate in either the 423 Component or Non-423 Component, but not both. Notwithstanding the foregoing, if any Affiliate or Subsidiary is disregarded for U.S. tax purposes in respect of the Company or any Designated Company participating in the 423 Component, then such disregarded Affiliate or Subsidiary shall automatically be a Designated Company participating in the 423 Component. If any Affiliate or Subsidiary is disregarded for U.S. tax purposes in respect of any Designated Company participating in the Non-423 Component, the Administrator may exclude such Affiliate or Subsidiary from participating in the Plan, notwithstanding that the Designated Company in respect of which such Affiliate or Subsidiary is disregarded may participate in the Plan. The Administrator may so designate any Affiliate or Subsidiary, or revoke any such designation, at any time and from time to time, either before or after the Plan is approved by the Company’s stockholders.

“Fair Market Value” of the Stock on any given date means the fair market value of the Stock determined in good faith by the Administrator; provided, however, that if the Stock is listed on the National Association of Securities Dealers Automated Quotation System (“NASDAQ”), NASDAQ Global Market, The New York Stock Exchange or another national securities exchange or traded on any established market, the determination shall be made by reference to the closing price on the immediately preceding trading day.

“Sale Event” means (i) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity, (ii) a merger, reorganization or consolidation pursuant to which the holders of the Company’s outstanding voting power and outstanding stock immediately prior to such transaction do not own a majority of the outstanding voting power and outstanding stock or other equity interests of the resulting or successor entity (or its ultimate parent, if applicable) immediately upon completion of such transaction, (iii) the sale of all of the Stock of the Company to an unrelated person, entity or group acting in concert, (iv) any other transaction in which the owners of the Company’s outstanding voting power immediately prior to such transaction do not own at least a majority of the outstanding voting power of the Company or any successor entity immediately upon completion of the transaction other than as a result of the acquisition of securities directly from the Company or (v) the approval by the stockholders of the Company of a complete liquidation or dissolution of the Company.

12. Rights on Termination of Employment. Unless otherwise required by applicable law, if a Participant’s employment terminates for any reason before the Exercise Date for any Offering, such Participant’s participation in the Plan will terminate immediately and no payroll deductions will be taken from any pay due and owing to the Participant on or after the termination date. The balance in the Participant’s account will be paid to such Participant or, in the case of such Participant’s death, to the Participant’s legal heirs. An employee will be deemed to have terminated employment, for this purpose, if the corporation that employs such employee, having been a Designated Company, ceases to be an Affiliate or a Subsidiary, or if the employee is transferred to any corporation other than the Company or a Designated Company. An employee will not be deemed to have terminated employment for this purpose, if the employee is on an approved leave of absence for military service or sickness or for any other purpose approved by the Company, if the employee’s right to reemployment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise provides in writing.

If a Participant transfers employment from the Company or any Designated Company participating in the 423 Component to any Designated Company participating in the Non-423 Component, such transfer will not be treated as a termination of employment, but the Participant shall immediately cease to participate in the 423 Component; however, any contributions made for the Offering in which such transfer occurs will be transferred to the Non-423 Component, and such Participant will immediately join the then-current Offering under the Non-423 Component upon the same terms and conditions in effect for the Participant’s participation in the 423 Component, except for such modifications otherwise applicable for Participants in such Offering. A Participant who transfers employment from any Designated Company participating in the Non-423 Component to the Company or any Designated Company participating in the 423 Component will not be treated as terminating the Participant’s employment and will remain a Participant in the Non-423 Component until the earlier of (i) the end of the current Offering under the Non-423 Component or (ii) the Offering Date of the first Offering in which the Participant is eligible to participate following such transfer. Notwithstanding the foregoing, the Administrator may establish different rules to govern transfers of employment between companies participating in the 423 Component and the Non-423 Component, consistent with the applicable requirements of Section 423 of the Code.

13. Special Rules and Sub-Plans. Notwithstanding any provision to the contrary in this Plan, the Administrator may adopt such special rules or sub-plans relating to the operation and administration of the Plan to accommodate local laws, customs and procedures for jurisdictions in which the Plan is offered, the terms of which sub-plans may take precedence over other provisions of this Plan, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan will govern the operation of such sub-plan. To the extent inconsistent with the requirements of Section 423 of the Code, any such sub-plan will be considered part of a Non-423 Offering, and Options granted thereunder will not be required by the terms of the Plan to comply with Section 423 of the Code. Without limiting the generality of the foregoing, the Administrator is authorized to adopt sub-plans for particular jurisdictions that modify or supplement the terms of the Plan to meet applicable local requirements, customs or procedures regarding, without limitation, (i) eligibility to participate, (ii) the definition of Compensation, (iii) the dates and duration of Offerings or Purchase Periods or other periods during which Participants may make payroll deductions to purchase of shares of Stock, (iv) the method of determining the Option Price and the discount from Fair Market Value at which shares of Stock may be purchased, (v) any minimum or maximum amount of payroll deductions a Participant may make in an Offering, Purchase Period or other

specified period under the applicable sub-plan, (vi) the treatment of Options upon a Sale Event or a change in capitalization of the Company, (vii) the handling of payroll deductions, (viii) establishment of bank or trust accounts to hold payroll deductions, (ix) payment of interest, (x) conversion of local currency, (xi) obligations to pay payroll tax, (xii) determination of beneficiary designation requirements, (xiii) withholding procedures and (xiv) handling of share issuances.

17. Adjustment in Case of Changes Affecting Stock. In the event of a subdivision of outstanding shares of Stock, the payment of a dividend in Stock or any other change affecting the Stock, the number of shares approved for the Plan and any other share limitations in the Plan shall be equitably or proportionately adjusted to give proper effect to such event. In the case of and subject to the consummation of a Sale Event, the Administrator, in its discretion, and on such terms and conditions as it deems appropriate, is hereby authorized to take any one or more of the following actions 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 or to facilitate such transactions or events:

(d) To provide that the Offering with respect to which an Option relates will be shortened by setting a New Exercise Date on which such Offering will end. The New Exercise Date will occur before the date of the Sale Event. 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

18. Section 409A. The 423 Component of the Plan and the Options granted pursuant to Offerings thereunder are intended to be exempt from the application of Section 409A of the Code. Neither the Non-423 Component nor any Option granted pursuant to an Offering thereunder is intended to constitute or provide for “nonqualified deferred compensation” within the meaning of Section 409A of the Code. Notwithstanding any provision of the Plan to the contrary, if the Administrator determines that any Option granted under the Plan is or may be or become subject to Section 409A of the Code or that any provision of the Plan may cause an Option granted under the Plan to be or become subject to Section 409A of the Code, the Administrator may adopt such amendments to the Plan and/or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions as the Administrator determines are necessary or appropriate to avoid the imposition of taxes under Section 409A of the Code.

19. Amendment of the Plan. The Board may at any time and from time to time amend the Plan in any respect, except that without the approval within 12 months of such Board action by the stockholders, no amendment may be made increasing the number of shares of Stock approved for issuance under the Plan or making any other change that would require stockholder approval in order for the 423 Component of the Plan, as amended, to qualify as an “employee stock purchase plan” under Section 423(b) of the Code, as determined by the Administrator.

20. Insufficient Shares. If the total number of shares of Stock that would otherwise be purchased on any Exercise Date plus the number of shares of Stock purchased under previous Offerings under the Plan exceeds the maximum number of shares of Stock issuable under the Plan, the shares then available shall be apportioned among Participants in proportion to the amount of payroll deductions accumulated on behalf of each Participant that would otherwise be used to purchase shares of Stock on such Exercise Date.

22. Governmental Regulations. The Company’s obligation to sell and deliver shares of Stock under the Plan is subject to obtaining all governmental approvals required in connection with the authorization, issuance or sale of such Stock and to compliance with all applicable provisions of law, domestic or foreign, including without limitation the U.S. Securities Act of 1933, as amended, and the U.S. Securities Exchange Act of 1934, as amended, the rules and regulations promulgated thereunder, and the requirements of any stock exchange or automated quotation system upon which the Stock may then be listed, exchange control restrictions and/or securities law restrictions.

25. Tax Withholding. Participation in the Plan is subject to any applicable U.S. and non-U.S. federal, state or local tax withholding requirements on income the Participant realizes in connection with the Plan. Each Participant agrees, by entering the Plan, that the Company or any Subsidiary or Affiliate may, but will not be obligated to, withhold from a Participant’s wages, salary or other compensation at any time the amount necessary for the Company or any Subsidiary or Affiliate to meet applicable withholding obligations, including any withholding required to make available to the Company or any Subsidiary or Affiliate any tax deductions or benefits attributable to the sale or disposition of Stock by such Participant. In addition, the Company or any Subsidiary or Affiliate may, but will not be obligated to, withhold from the proceeds of the sale of Stock or use any other method of withholding that the Company or any Subsidiary or Affiliate deems appropriate to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f) with respect to the 423 Component. The Company will not be required to issue any shares of Stock under the Plan until such obligations are satisfied.

26. Notification Upon Sale of Shares Under the 423 Component. Each Participant who is subject to tax in the United States and participates in the 423 Component agrees, by entering the Plan, to give the Company prompt notice of any disposition of shares of Stock purchased under the Plan where such disposition occurs within two years after the date of grant of the Option pursuant to which such shares were purchased or within one year after the date such shares were purchased.
