1.Purpose. The purpose of the Plan is to provide incentive for present and future eligible Employees to acquire equity interests (or increase existing equity interests) in the Company through the purchase of Shares. It is the Company’s intention that the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code. Accordingly, the provisions of the Plan shall be administered, interpreted and construed in a manner consistent with the requirements of that section of the Code.

(c)“Applicable Percentage” means, with respect to each Exercise Period, 85% unless and until such Applicable Percentage is increased by the Committee, in its discretion, provided that any such increase in the Applicable Percentage with respect to a given Exercise Period must be established prior to the commencement of the Enrollment Period for such Exercise Period.

(e)“Code” means the United States Internal Revenue Code of 1986, as amended, and any successor thereto. Reference to a specific section of the Code or United States Treasury Regulation thereunder will include such section or regulation, any valid regulation or other official applicable guidance promulgated under such section, and any comparable successor provision or other provision of any future legislation or regulation amending, supplementing or superseding such section or regulation.

(i)“Compensation” means, with respect to each Participant for each pay period: base salary, wages, overtime, and shift premium paid to such Participant by the Company or a Designated Subsidiary. Except as otherwise determined by the Committee, “Compensation” does not include: (i) any amounts contributed by the Company or a Designated Subsidiary to any pension plan, (ii) any automobile, relocation or housing allowances, or reimbursement for any expenses, including automobile, relocation or housing expenses, (iii) any amounts paid as a bonus, including a starting bonus, referral fee, annual bonus, relocation bonus,

or sales incentives or commissions, (iv) any amounts realized from the exercise of any stock options or other incentive awards, (v) any amounts paid by the Company or a Designated Subsidiary for other fringe benefits, such as health and welfare, hospitalization and group life insurance benefits, disability pay, or perquisites, or paid in lieu of such benefits, or (vi) other similar forms of extraordinary compensation.

(l)“Employee” means any individual designated as an employee of the Company or a Designated Subsidiary on the payroll records thereof. Employee status shall be determined consistent with Treasury Regulation section 1.421-1(h). For purposes of clarity, the term “Employee” shall not include the following, regardless of any subsequent reclassification as an employee by the Company or a Designated Subsidiary, any governmental agency, or any court: (i) any independent contractor; (ii) any consultant; (iii) any individual performing services for the Company or a Designated Subsidiary who has entered into an independent contractor or consultant agreement with the Company or a Designated Subsidiary; (iv) any individual performing services for the Company or a Designated Subsidiary under an independent contractor or consultant agreement, a purchase order, a supplier agreement or any other agreement that the Company or a Designated Subsidiary enters into for services; (v) any individual classified by the Company or a Designated Subsidiary as contract labor (such as contractors, contract employees, job shoppers), regardless of length of service; and (vi) any leased employee. The Committee shall have discretion to determine whether an individual is an Employee for purposes of the Plan, in a manner consistent with Section 423 of the Code.

(n)“Entry Date” means the first Trading Day of each Exercise Period; provided, that in the case of an individual who becomes eligible to become a Participant under Section 3 after the first Trading Day of an Exercise Period (if applicable under the Exercise Periods established by the Committee pursuant to Section 4(b)), the term “Entry Date” shall mean the first Trading Day of the Purchase Period occurring on or after the day on which that individual becomes a Participant.

(r)“Exercise Period” means, subject to adjustment as provided in Section 4(b), the approximately three-month period beginning on: (i) March 1 of each year and ending the last day of May of such year, (ii) June 1 of each year and ending on the last day of August of such year, (iii) September 1 of each year and ending on the last day of November of such year or (iv) December 1 of each year and ending on the last day of February of the following year, until the Plan terminates.

(t)“Fair Market Value” means, if the Shares are listed on a national securities exchange, as of any given date, the closing price for a Share on such date on the Applicable Exchange, or if Shares were not traded on the Applicable Exchange on such measurement date, then on the closest preceding date on which Shares are so traded, all as reported by such source as the Committee may select. If the Shares are not listed on a national securities exchange, the Fair Market Value of a Share shall mean the amount determined by the Board in good faith, and in a manner consistent with Section 423 of the Code to be the fair market value of a Share.

(v)“Offering” means an offering of an option granted under the Plan during an Exercise Period as further described in Section 4. Unless otherwise determined by the Committee, each Offering to the Employees of the Company and of a Designated Subsidiary shall be deemed a separate Offering under the Plan, even if the dates and other terms of the applicable Exercise Periods of each such Offering are identical, and the provisions of the Plan will separately apply to each such Offering. The terms of separate Offerings need not be identical provided that the terms of the Plan and an Offering together satisfy Section 423 of the Code.

Employee shall be considered to be continuing intact while such Participant is on military leave, sick leave, or other bona fide leave of absence approved by the Committee or the Participant’s supervisor; provided further, however, that if such period of leave of absence exceeds three months, and the Participant’s right to reemployment is not provided either by statute or by contract, the Participant’s status as an Employee shall be deemed to have terminated on the first day immediately following such three-month period. Unless otherwise determined by the Committee (on a uniform and nondiscriminatory basis), a transfer of a Participant’s employment between or among the Company and/or the Designated Subsidiaries of the Plan shall not be considered a Terminating Event.

(b)Certain Exceptions. Notwithstanding Section 3(a), the Committee, in its discretion, from time to time may, prior to an Entry Date for all options to be granted in one or more separate Offerings, determine on a uniform and nondiscriminatory basis that an Employee will not be eligible to participate in the Plan if he or she: (i) has not completed at least two years of service since his or her last hire date (or such lesser period of time as may be determined by the Committee in its discretion), (ii) customarily works not more than 20 hours per week (or such lesser period of time as may be determined by the Committee in its discretion), (iii) is a highly compensated employee within the meaning of Section 414(q) of the Code or (iv) is a highly compensated employee within the meaning of Section 414(q) of the Code with compensation above a certain level or who is an officer or subject to the disclosure requirements of Section 16(a) of the Exchange Act, provided the exclusion is applied with respect to each separate Offering in an identical manner to all Employees of the Designated Subsidiary participating in that Offering. In addition, notwithstanding Section 3(a), eligible Employees who are citizens or residents of a non-U.S. jurisdiction may be excluded from the Plan if (1) the grant of an option under the Plan or any Offering to a citizen or resident of the non-U.S. jurisdiction is prohibited under the laws of such jurisdiction, or (2) compliance with the laws of the non-U.S. jurisdiction would cause the Plan or the Offering to violate the requirements of Section 423 of the Code, in each case, to the extent allowed under Section 423 of the Code.

(a)In General. The Plan shall generally be implemented by a series of Exercise Periods, each of which lasts approximately three months, subject to Section 4(b) below. Unless and until the Committee determines otherwise in its discretion, each Exercise Period will consist of one approximately three-month Purchase Period, which will run simultaneously with the Exercise Period.

(b)Changes by Committee. The Committee shall have the authority to make changes to the occurrence, duration and/or the frequency of Exercise Periods, including, without limitation, to establish additional or alternative sequential or overlapping Exercise Periods, a different number of Purchase Periods within an Exercise Period, a different duration for one or more Exercise Periods or Purchase Periods or different commencement or ending dates for such Exercise Periods with respect to future Exercise Periods if any such change is announced prior to the scheduled beginning of the first Exercise Period to be affected; provided that the duration of an Exercise Period may not exceed 27 months (or the expiration of such other applicable period specified under Section 423(b)(7) of the Code). To the extent that the Committee establishes

additional or overlapping Exercise Periods, the Committee will have discretion to structure an Exercise Period so that if the Fair Market Value of a Share on the first Trading Day of the Exercise Period in which a Participant is currently enrolled is higher than the Fair Market Value of a Share on the first Trading Day of any subsequent Exercise Period, the Company will automatically enroll such Participant in the subsequent Exercise Period and will terminate his or her participation in such original Exercise Period.

(a)Shares Subject to Option. On a Participant’s Entry Date, subject to the limitations set forth in Section 6(c), the Participant shall be granted an option to purchase on the subsequent Exercise Date (at the Exercise Price determined as provided in Section 6(b) below) up to a number of Shares determined by dividing such Participant’s Plan Contributions accumulated during the current Exercise Period prior to such Exercise Date and retained in the Participant’s account as of such Exercise Date by the Exercise Price; provided that the maximum number of Shares a Participant may purchase during any Exercise Period shall be that whole number of Shares determined by dividing $25,000 by the Fair Market Value of a Share on the Entry Date of such Exercise Period; provided further that such maximum number of Shares may instead be established by the Committee as a fixed number or a different predetermined formula with respect to any Exercise Period prior to the Entry Date thereof. All Participants granted options pursuant to an Exercise Period shall have the same rights and privileges within the meaning of Section 423(b)(5) of the Code. Unless otherwise determined by the Committee, no fractional Shares shall be issued or otherwise transferred upon the exercise of an option under the Plan.

(b)Exercise Price. The Exercise Price offered to each Participant in a given Exercise Period shall be no lower than the Applicable Percentage of the lesser of (i) the Fair Market Value of a Share on the Participant’s Entry Date or (ii) the Fair Market Value of a Share on the Exercise Date. Unless otherwise determined by the Committee, the Exercise Price shall be the Applicable Percentage of the Fair Market Value of a Share on the Exercise Date; provided that any change in the Exercise Price with respect to a given Exercise Period must be established prior to the commencement of the Enrollment Period for such Exercise Period.

(c)Limitations on Options that may be Granted. Notwithstanding any provision of the Plan to the contrary, (i) no Employee may participate in the Plan if such Employee, immediately after the applicable Entry Date, would be deemed for purposes of Section 423(b)(3) of the Code to possess five percent or more of the total combined voting power or value of all classes of stock of the Company or of any Subsidiary or of any other related corporation for purposes of Section 423 of the Code, and (ii) no Participant shall be granted an option under the Plan which permits his or her right to purchase Shares under the Plan to accrue at a rate which, when aggregated with such Participant’s rights to purchase shares under all other employee stock purchase plans of the Company and any Subsidiary, and any other related corporation for purposes of Section 423 of the Code, which are intended to qualify under Section 423 of the Code, exceeds $25,000 in Fair Market Value (or such other limit, if any, as may be imposed by the Code) for each calendar year in which such option is outstanding at any time. For purposes of clause (ii) of the preceding sentence, the Fair Market Value of Shares purchased with respect to a given Exercise Period shall be determined as of the Entry Date for such Exercise Period. The limitations set forth in this Section 6(c) shall be applied in conformance with applicable regulations under Section 423(b)(8) of the Code.

(e)Bookkeeping Accounts Maintained. Individual bookkeeping accounts shall be maintained for each Participant. All Plan Contributions from a Participant’s Compensation shall be credited to such Participant’s Plan account. Except as otherwise required by Applicable Law (i) all Plan Contributions made for a Participant shall be deposited in the Company’s or a Designated Subsidiary’s general corporate accounts, and no interest shall accrue or be credited with respect to a Participant’s Plan Contributions, and (ii) all Plan Contributions received or held by the Company or a Designated Subsidiary may be used by the Company or such Designated Subsidiary for any corporate purpose, and neither the Company nor such Designated Subsidiary shall be obligated to segregate or otherwise set apart such Plan Contributions from any other corporate funds.

(b)Plan Contributions Election. At the time a Participant enrolls with respect to an Exercise Period in accordance with Section 5, the Participant shall authorize Plan Contributions from his or her Compensation to be made on each payroll date during the portion of the Exercise Period that he or she is a Participant in an amount not less than 1% and not more than 15% of the Participant’s Compensation on each payroll date during the portion of the Exercise Period that he or she is a Participant, or such other maximum amount as may be determined by the Committee. The amount of Plan Contributions must be a whole percentage (e.g., 1%, 2%, 3%, etc.) of the Participant’s Compensation. The amount of Plan Contributions may be adjusted to the extent required by Applicable Law.

(c)Commencement of Plan Contributions. Except as otherwise determined by the Committee under rules applicable to all Participants, Plan Contributions shall commence with the earliest administratively practicable pay date on or after the Entry Date with respect to which the Participant enrolls in accordance with Section 5, or is deemed to have elected continued participation in the Plan with respect to succeeding Exercise Periods in accordance with Section 7(d).

(d)Automatic Continuation of Plan Contributions for Succeeding Exercise Periods. With respect to each succeeding Exercise Period, a Participant shall be deemed (i) to have elected to participate in such immediately succeeding Exercise Period (and, for purposes of such Exercise Period, the Participant’s “Entry Date” shall be the first Trading Day of such succeeding Exercise Period), and (ii) to have authorized the same rate of Plan Contributions for such immediately succeeding Exercise Period as was in effect for the Participant immediately prior to the commencement of such succeeding Exercise Period, unless such Participant elects otherwise prior to the Entry Date of such succeeding Exercise Period, in accordance with Section 7(e) below or such Participant withdraws from the Plan in accordance with Section 11(a) hereof.

(e)Change of Plan Contributions Election. A Participant may not decrease or increase the rate of his or her Plan Contributions during an Exercise Period. Using the authorization process designated for this purpose by the Company in accordance with Section 5 above authorizing a change in the rate of Plan Contributions, a Participant may decrease or

increase the rate of his or her Plan Contributions (within the limitations of Section 7(b) above) commencing with the first Exercise Period that begins after the date of such authorization. Additionally, a Participant may withdraw from an Exercise Period as provided in Section 11(a) hereof. The Committee has the authority to change the foregoing rules.

(f)Automatic Changes in Plan Contributions. The Company may decrease a Participant’s rate of Plan Contributions, but not below zero percent, at any time during an Exercise Period to the extent necessary to comply with Section 423(b)(8) of the Code or any other Applicable Law or Section 6(a) or Section 6(c). Plan Contributions shall recommence at the rate provided in the Participant’s enrollment at the beginning of the first Exercise Period beginning in the following calendar year, unless the Participant’s participation in the Plan terminates as provided in Section 11.

(a)Exercise of Options. On each Exercise Date, the option for the purchase of Shares of each Participant who has not withdrawn from the Plan and whose participation in the Exercise Period has not otherwise terminated before the Exercise Date shall be automatically exercised to purchase the number of whole Shares determined by dividing (i) the total amount of the accumulated Plan Contributions then credited to the Participant’s account under the Plan during the Exercise Period and not previously applied toward the purchase of Shares by (ii) the Exercise Price, subject to the limitations in Section 6(a) and Section 6(c) and any other limitation in the Plan. Notwithstanding the foregoing, the Committee may permit the purchase of whole and fractional Shares upon exercise of options hereunder, commencing with the first Exercise Period that begins after the date of such Committee authorization.

(b)Pro Rata Allocation of Shares. If the aggregate number of Shares to be purchased by all Participants in the Plan and the International Plan on an Exercise Date exceeds the number of Shares available as provided in Section 12(a), the Company shall make a pro rata allocation of the remaining Shares in as uniform a manner as practicable and as the Company determines to be equitable. Unless otherwise determined by the Committee, any fractional Share resulting from such pro rata allocation to any Participant shall be disregarded and shall not be issued.

(c)Delivery of Shares. As soon as practicable after each Exercise Date, the Company shall arrange the delivery of the Shares purchased by each Participant on such Exercise Date to a broker designated by the Company that will hold such Shares for the benefit of each such Participant; provided that the Company may arrange the delivery to a Participant of a certificate representing such Shares. Shares to be delivered to a Participant under the Plan shall be registered in the name of the Participant, or, if requested by the Participant, in the name of the Participant and his or her spouse, or, if applicable, in the names of the heirs of the Participant.

(d)Return of Cash Balance. Any cash balance remaining in a Participant’s Plan account following any Exercise Date shall be refunded to the Participant as soon as practicable after such Exercise Date. However, if the cash balance to be returned to a Participant pursuant to the preceding sentence is less than the amount that would have been necessary to purchase an additional whole Share on such Exercise Date, the Company may arrange for the cash balance to be retained in the Participant’s Plan account and applied toward the purchase of Shares in the subsequent Exercise Period, as the case may be.

(e)Tax Withholding. At the time of any tax withholding event under the Plan, the Participant shall make adequate provision for the Tax-Related Items withholding obligations, if any, of the Company and/or the applicable Designated Subsidiary which arise upon such tax withholding event. The Company and/or applicable Designated Subsidiary may, but shall not be

(g)Provision of Reports to Participants. Unless otherwise determined by the Committee, each Participant who has exercised all or part of his or her option under the Plan shall receive, as soon as practicable after the Exercise Date, a report of such Participant’s Plan account setting forth the total Plan Contributions accumulated prior to such exercise, the number of Shares purchased, the Exercise Price for such Shares, the date of purchase and the cash balance, if any, remaining immediately after such purchase that is to be refunded or retained in the Participant’s Plan account pursuant to Section 8(d). The report pursuant to this Section 8(g) may be delivered in such form and by such means, including by electronic transmission, as the Company may determine.

(a)Deposit of Shares into ESPP Brokerage Account. Notwithstanding any other provisions of the Plan to the contrary, the Company may require that the Shares purchased on behalf of each Participant under the Plan shall be deposited directly into a brokerage account which the Company may establish for the Participant at a Company-designated brokerage firm (such an account, the “ESPP Brokerage Account”).

(b)Required Holding Period. The Shares deposited into a Participant’s ESPP Brokerage Account may not be transferred from the ESPP Brokerage Account or disposed of (whether electronically or in certificated form) or pledged until the required holding period, if any, for those Shares is satisfied. The Committee shall have discretion to determine whether a holding period shall apply with respect to Participants generally. Following expiration of any such required holding period, a Participant may sell Shares held in his or her ESPP Brokerage Account at any time (subject to the Expedia Securities Trading Policy and Applicable Law), but in the absence of any such sale, a Participant shall be required to hold such Shares in the ESPP Brokerage Account until expiration of the holdings periods specified by Section 423(a)(1) of the Code applicable to such Shares.

10.Transferability. Neither Plan Contributions credited to a Participant’s account nor any option or rights to exercise any option or receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will or the laws of descent and distribution). Any attempted such assignment, transfer, pledge or other disposition

(a)Withdrawal. A Participant may withdraw from an Exercise Period at any time by giving written notice to the Company (or a person or firm designated by the Company) in the manner and/or through the website designated by the Company. A notice of withdrawal must be received no later than the deadline prescribed by the Company, which deadline may be changed from time to time with appropriate notice to Employees.

Plan Contributions shall cease as soon as administratively practicable after receipt by the Company of the Participant’s notice of withdrawal, and, subject to administrative practicability, no further purchases shall be made for the Participant’s account. All Plan Contributions credited to such Participant’s account, if any, and not yet used to purchase Shares, shall be returned to the Participant as soon as administratively practicable after receipt of the Participant’s notice of withdrawal. Such Participant’s unexercised options to purchase Shares pursuant to the Plan shall be automatically terminated. Plan Contributions will not resume on behalf of a Participant who has withdrawn from the Plan (a “Former Participant”) unless the Former Participant enrolls in a subsequent Exercise Period in accordance with Section 5 and subject to the restriction provided in Section 11(b), below.

(b)Effect of Withdrawal on Subsequent Participation. A Former Participant who has withdrawn from the Plan pursuant to Section 11(a) shall be eligible to participate in the Plan at the beginning of the next Exercise Period following the date the Former Participant withdrew, and the Former Participant must submit a new enrollment in accordance with Section 5 in order to again become a Participant.

(c)Terminating Event. If a Participant has a Terminating Event, (i) such individual may not make further Plan Contributions, (ii) any amount of cash then credited to his or her Plan account shall, as determined by the Committee (on a uniform and nondiscriminatory basis for all options to be granted in an Offering), either be (A) promptly returned to such individual following the date of such Terminating Event, or (B) used to purchase the number of Shares in accordance with and subject to Sections 8(a) through (c), and (e) through (g), and any cash balance remaining in such individual’s Plan account following such Exercise Date shall be promptly refunded to such individual following the Exercise Date, and (iii) all Shares held in such Participant’s ESPP Brokerage Account shall continue to be held in such ESPP Brokerage Account unless the individual sells or transfers such Shares, subject to satisfaction of both any required holding period (provided that any such required holding period shall not apply in the case of a Terminating Event due to death) and the Code Section 423(a)(1) holding period requirements, as referenced in Section 9(b). For the avoidance of doubt, in the event that the employment of a Participant is transferred, and such Participant becomes an employee of a Subsidiary that is not a Designated Subsidiary under the Plan, such Participant shall have a Terminating Event.

(a)Number of Shares. Subject to adjustment as provided in Section 12(b), the maximum number of Shares that may be issued under the Plan and the International Plan in the aggregate shall be 3,500,000 Shares, which reflects an increase of 1,000,000 over the number of Shares authorized under the Plan prior to the Effective Date. Such Shares issuable under the Plan may be authorized and unissued shares (which will not be subject to preemptive rights), Shares held in treasury by the Company, Shares purchased on the open market or by private purchase or any combination of the foregoing. Any Shares issued under the Plan shall reduce on a Share-for-

Share basis the number of Shares available for subsequent issuance under the Plan and the International Plan. If an outstanding option under the Plan or the International Plan for any reason expires or is terminated or cancelled, the Shares allocable to the unexercised portion of such option shall again be available for issuance under the Plan or the International Plan. For avoidance of doubt, up to the maximum number of Shares reserved under this Section 12(a) may be used to satisfy purchases of Shares under the Plan and any remaining portion of such maximum number of Shares may be used to satisfy purchases of Shares under the International Plan.

(i.)If the outstanding Shares are increased or decreased, or are changed into or are exchanged for a different number or kind of shares, including as a result of one or more mergers, reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends or the like, or there occurs a separation, spin-off or other distribution of stock or property (including any extraordinary dividend, but excluding any ordinary dividends) affecting the Company and without the Company’s receipt of consideration, then appropriate adjustments shall be made to the number and/or kind of shares available for issuance in the aggregate under the Plan and the International Plan and under each outstanding option under the Plan and to the Exercise Price thereof, in each case as determined by the Committee, in its discretion, and the Committee’s determination shall be conclusive.

(ii.)In the event of any proposed dissolution or liquidation of the Company, immediately prior to the consummation of such proposed action, any outstanding Exercise Period will terminate, and any Shares held in ESPP Brokerage Accounts, and all Plan Contributions credited to Participant Plan accounts and not used to purchase Shares, shall be distributed to each applicable Participant, unless otherwise provided by the Committee.

(iii.)In the event of sale of all or substantially all of the Company’s assets, or a merger, amalgamation, consolidation, acquisition or sale or exchange of shares or similar event affecting the Company (each, a “Company Transaction”), then, as determined by the Committee, in its discretion, which determination shall be conclusive, either:

(1)each option under the Plan shall be assumed or an equivalent option shall be substituted by the Company’s successor corporation or a parent corporation (as defined in Section 424(e) of the Code) of such successor corporation, unless the Committee determines, in the exercise of its discretion, and in lieu of such assumption or substitution, to shorten the Exercise Period(s) then in progress by setting a new Exercise Date (the “New Exercise Date”). If the Committee shortens the Exercise Period(s) then in progress in lieu of assumption or substitution in the event of a Company Transaction, the Company shall notify each Participant in writing, prior to the New Exercise Date, that the Exercise Date for such Participant’s option has been changed to the New Exercise Date, and that such Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Plan as provided in Section 11(a). For purposes of this Section 12(b), an option granted under the Plan shall be deemed to have been assumed if, following the Company Transaction, the option confers the right to purchase, for each Share subject to the option immediately prior to the Company Transaction, the consideration (whether stock, cash or other securities or property) received in the Company Transaction by holders of Shares for each Share held on the effective date of the Company Transaction (and if such holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, that if the consideration received in the Company Transaction was not

solely common stock or Shares of the successor corporation or its parent corporation (as defined in Section 424(e) of the Code), the Committee may, with the consent of the successor corporation, provide for the consideration to be received upon exercise of the option to be solely common stock of the successor corporation or its parent corporation equal in fair market value to the per share consideration received by the holders of Shares in the Company Transaction; or

(iv.)In all cases, the Committee shall have discretion to exercise any of the powers and authority provided under this Section 12, and the Committee’s actions hereunder shall be final and binding on all Participants. Unless otherwise determined by the Committee, no fractional shares of stock shall be issued under the Plan pursuant to any adjustment authorized under the provisions of this Section 12.

(a)Committee as Administrator. The Plan shall be administered by the Committee. The Committee shall have all authority that may be necessary or helpful to enable it to discharge its responsibilities with respect to the Plan. Without limiting the generality of the foregoing sentences of this Section 13, subject to the express provisions of the Plan and Applicable Law, the Committee shall have full and exclusive discretionary authority to interpret and construe any and all provisions of the Plan and any agreements, forms, and instruments relating to the Plan; prescribe the forms and manner of any agreements, forms, and instruments, and all online enrollment, designation or communication, relating to the Plan; determine eligibility to participate in the Plan including which Subsidiaries shall be Designated Subsidiaries; adopt rules and regulations for administering the Plan; adjudicate and determine all disputes arising under or in connection with the Plan; determine whether a particular item is included in “Compensation;” permit Plan Contributions in excess of the amount designated by a Participant in order to adjust for administrative errors in the Company’s processing of properly submitted enrollment agreements and/or changes in contribution amounts; retain and engage such third parties as it shall determine to assist with the administration of the Plan and make all other determinations necessary or advisable for the administration of the Plan. All decisions, actions and determinations by the Committee with respect to the Plan; any agreement, form or instrument relating to the Plan; or any operation or administration of the Plan shall be final, conclusive and binding on all persons.

(b)Delegation. Subject to Applicable Law, the Committee may, in its discretion, from time to time, delegate all or any part of its responsibilities and powers under the Plan to any employee or group of employees of the Company or any Subsidiary or to any other person or body, and revoke any such delegation. Notwithstanding the foregoing, the Board, in its absolute discretion, may at any time and from time to time exercise any and all rights, duties and responsibilities of the Committee under the Plan, including, but not limited to, establishing procedures to be followed by the Committee.

(a)Amendment of the Plan. The Board or the Committee may at any time, or from time to time, amend the Plan in any respect; provided that (i) except as otherwise provided by Section 4(b) or Section 12(b), or to comply with any Applicable Law, no such amendment may make any change in any option theretofore granted which materially adversely affects the previously accrued rights of any Participant with respect to any such option without such

Participant’s consent, and (ii) the Plan shall not be amended in any way that will cause options issued under the Plan to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Code. To the extent necessary to comply with Section 423 of the Code, or any other Applicable Law, regulation or rule, the Company shall obtain stockholder approval of any such amendment.

(b)Suspension of the Plan. The Board or the Committee may, at any time, suspend the Plan; provided that the Company shall provide notice to the Participants prior to the effectiveness of such suspension. The Board or the Committee may resume the operation of the Plan following any such suspension; provided that the Company shall provide notice to the Participants prior to the date of termination of the suspension period. A Participant shall remain a Participant in the Plan during any suspension period (unless he or she withdraws pursuant to Section 11(a)), however, no options shall be granted or exercised, and no Plan Contributions shall be made in respect of any Participant during the suspension period.

Notwithstanding the foregoing to the contrary, (i) the Board may at any time, with notice to Participants, terminate an Exercise Period then in progress and provide, in its discretion, that the outstanding balance of Plan Contributions credited to Participant Plan accounts and not yet used to purchase Shares shall either be (x) used to purchase Shares on an early Exercise Date established by the Board, or (y) distributed to the applicable Participants, and (ii) upon any termination of the Plan, any Exercise Period then in progress shall be treated as may be determined by the Board in accordance with clause (i) of this sentence, and any Shares held in ESPP Brokerage Accounts may be distributed to the applicable Participants.

(i.)Rights or Claims. No person shall have any rights or claims under the Plan except in accordance with the provisions of the Plan and any applicable agreement thereunder. The liability of the Company or any Designated Subsidiary under the Plan is limited to the obligations expressly set forth in the Plan, and no term or provision of the Plan may be construed to impose any further or additional duties, obligations, or costs on the Company, any Designated Subsidiary or any other affiliate thereof or the Board or the Committee not expressly set forth in the Plan. The grant of any option under the Plan

shall not confer any rights upon the Participant holding such option other than such terms, and subject to such conditions, as are specified in the Plan as being applicable to such option, or to all options. Without limiting the generality of the foregoing, neither the existence of the Plan nor anything contained in the Plan or in any agreement thereunder shall be deemed to:

(4)give any Employee of the Company or any Designated Subsidiary the right to receive any bonus, whether payable in cash or in Shares, or in any combination thereof, from the Company and/or a Designated Subsidiary, nor be construed as limiting in any way the right of the Company and/or a Designated Subsidiary to determine, in its discretion, whether or not it shall pay any Employee bonuses, and, if so paid, the amount thereof and the manner of such payment; or

(iii.)No Effects on Benefits; No Damages. Any compensation received by a Participant under an option is not part of any (1) normal or expected compensation or salary for any purpose, as an employee or otherwise; (2) termination, indemnity, severance, resignation, redundancy, end of service payments; (3) bonuses; (4) long-service awards; (5) pension or retirement benefits or (6) similar payments under any laws, plans, contracts, policies, programs, arrangements or otherwise, in each case, otherwise payable or provided to such Participant. A Participant shall, by participating in the Plan, waive any and all rights to compensation or damages in consequence of termination of employment of such Participant for any reason whatsoever, whether lawfully or otherwise, insofar as those rights arise or may arise from such Participant ceasing to have rights under the Plan as a result of such termination of employment, or from the loss or diminution in value of such rights or entitlements, including by reason of the operation of the terms of the Plan or the provisions of any statute or law relating to taxation. No claim or entitlement to compensation or damages arises from the termination of the Plan or diminution in value of any option or Shares purchased under the Plan.

(iv.)No Effect on Other Plans. Neither the adoption of the Plan nor anything contained herein shall affect any other compensation or incentive plans or arrangements of the Company or any Designated Subsidiary, or prevent or limit the right of the Company or any Designated Subsidiary to establish any other forms of incentives or compensation for their employees or grant or assume options or other rights otherwise than under the Plan.

(d)Participants Deemed to Accept Plan. By enrolling in the Plan and accepting any benefit thereunder, each Participant and each person claiming under or through any such Participant shall be conclusively deemed to have indicated their acceptance and ratification of, and consent to, all of the terms and conditions of the Plan and any action taken under the Plan by the Board, the Committee or the Company, in any case in accordance with the terms and conditions of the Plan.

(e)Uncertificated Shares. To the extent that the Plan provides for issuance of certificates to reflect the transfer of Shares, the transfer of such Shares may nevertheless be effected on a uncertificated basis, to the extent not prohibited by Applicable Law. Notwithstanding any contrary Plan provisions prescribing the manner and form in which stock certificates may be issued and/or Shares may be held by or on behalf of Participants, the Company and any affiliate thereof shall have the right to make such alternative arrangements as they may, in their discretion, determine, and which may include the transfer of Shares and/or the issue of stock certificates to any nominee or trust or other third party arrangement established for the benefit in whole or in part of Participants.

(f)Governing Law. The Plan and each agreement thereunder shall be governed by and construed in accordance with the laws of the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of the Plan to the substantive law of another jurisdiction. Participants are deemed to submit to the exclusive jurisdiction and venue of the federal or state courts of the State of Delaware to resolve any and all issues that may arise out of or relate to the Plan or any related agreement.

(g)No Constraint on Corporate Action. Nothing contained in the Plan shall be construed to prevent the Company or any Designated Subsidiary from taking any corporate action (including the Company’s right or power to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, or to merge or consolidate, or dissolve, liquidate, sell, or transfer all or any part of its business or assets) which is deemed by it to be appropriate, or in its best interest, whether or not such action would have an adverse effect on the Plan, or any rights awarded Participants under the Plan. No employee, beneficiary, or other person, shall have any claim against the Company or any Designated Subsidiary as a result of any such action.

(i.)The Plan, the granting, acceptance and exercise of options and the issuance of Shares 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 Laws, and to such approvals by any governmental agencies or national securities exchanges as may be required.

(ii.)If at any time the Committee shall determine, in its discretion, that the listing, registration and/or qualification of Shares upon any securities exchange or under any state, Federal or non-United States law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of, or in connection with, the sale or purchase of Shares hereunder, the Company shall have no obligation to allow the grant or exercise of any option under the Plan, or to issue or deliver evidence of title for Shares issued under the Plan, in whole or in part, unless and until such listing, registration, qualification, consent and/or approval shall have been effected or obtained, or otherwise provided for, free of any conditions not acceptable to the Committee.

(iii.)If at any time counsel to the Company shall be of the opinion that any sale or delivery of Shares pursuant to an option is or may be in the circumstances unlawful or result in the imposition of excise taxes on the Company, any Designated Subsidiary or any affiliate respectively thereof under the statutes, rules or regulations of any applicable jurisdiction, the Company shall have no obligation to make such sale or delivery, or to make any application or to effect or to maintain any qualification or registration under the United States Securities Act of 1933, as amended, or otherwise with respect to Shares or options, and the right to exercise any option under the Plan shall be suspended until, in the opinion of such counsel, such sale or delivery shall be lawful or will not result in the imposition of excise taxes on the Company, any Designated Subsidiary or any such affiliate.

(iv.)Upon termination of any period of suspension under Section 15(i)(iii), any option affected by such suspension which shall not then have expired or terminated shall be reinstated as to all Shares available before such suspension and as to the Shares which would otherwise have become available during the period of such suspension, but no suspension shall extend the term of any option.

(v.)The Committee may require each person receiving Shares in connection with any option under the Plan to represent and agree with the Company in writing that such person is acquiring such Shares for investment without a view to the distribution thereof, and/or provide such other representations and agreements as the Committee may prescribe. The Committee, in its absolute discretion, may impose such restrictions on the ownership and transferability of the Shares purchasable or otherwise receivable by any person under any option as it deems appropriate. Any such restrictions may be set forth in the applicable agreement, and the certificates evidencing such shares may include any legend that the Committee deems appropriate to reflect any such restrictions.

(j)Tax Qualification. Although the Company may endeavor to (1) qualify an option for favorable tax treatment under the laws of the United States or (2) avoid adverse tax treatment, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment, notwithstanding anything to the contrary in this Plan. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact on Participants under the Plan.

(k)Electronic Delivery. Any reference in the Plan or any related agreement to an agreement, document, statement, instrument or notice, whether written or otherwise, will include any agreement, document, statement, instrument or notice delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s intranet.
