5

Committee in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such Committee did not act in good faith and in a manner which such person reasonably believed to be in the best interests of the Company, or in the case of a criminal proceeding, had no reason to believe that the conduct complained of was unlawful; provided, however, that within 60 days after institution of any such action, suit or proceeding, such Committee shall, in writing, offer the Company the opportunity at its own expense to handle and defend such action, suit or proceeding.

4.1    Subject to adjustment in accordance with Section 11, a total of (i) 11,450,000 Ordinary Shares shall be available for the grant of Awards under the Plan; plus (ii) the number of Ordinary Shares underlying any awards under the Company’s 2014 Equity Incentive Plan, as amended, that are forfeited, canceled or otherwise terminated (other than by exercise or withheld by the Company to satisfy any tax withholding obligation) on or after the Effective Date shall be added to the Ordinary Shares available for issuance under (i) hereof; provided that no more than 11,450,000 Ordinary Shares may be issued upon the exercise of Incentive Share Options. During the terms of the Awards, the Company shall keep available at all times the number of Ordinary Shares required to satisfy such Awards. Notwithstanding the foregoing, to the extent permitted by Applicable Laws, Awards that provide for the delivery of Ordinary Shares subsequent to the applicable grant date may be granted in excess of the share limits set forth in this paragraph if such Awards provide for the forfeiture of such Awards to the extent that insufficient Ordinary Shares remain at the time that the Ordinary Shares would otherwise be issued in respect of such Award.

4.2    Ordinary Shares available for distribution under the Plan may consist, in whole or in part, of authorized and unissued shares, treasury shares or shares reacquired by the Company in any manner.

4.3    Any Ordinary Shares subject to an Award that is canceled, forfeited or expires prior to exercise or realization, either in full or in part, shall again become available for issuance under the Plan.

5.1    Eligibility for Specific Awards. Incentive Share Options may be granted only to Employees who are tax residents of the United States and shall not include Employees who are solely Officers and Directors. Awards other than Incentive Share Options may be granted to Employees, Consultants and Directors.

5.2    Ten Percent Shareholders. A Ten Percent Shareholder shall not be granted an Incentive Share Option unless the Option Exercise Price is at least 110% of the Fair Market Value of an Ordinary Share at the Grant Date and the Option is not exercisable after the expiration of five years from the Grant Date.

6.    Option Provisions. Each Option granted under the Plan shall be evidenced by an Award Agreement. Each Option so granted shall be subject to the conditions set forth in this Section 6, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options shall be separately designated Incentive Share Options or Non-qualified Share Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will be issued for Ordinary Shares purchased on exercise of each type of Option. Notwithstanding the foregoing, the Company shall have no liability to any Participant or any other person if an Option designated as an Incentive Share Option fails to qualify as such at

6

any time or if an Option is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code and the terms of such Option do not satisfy the requirements of Section 409A of the Code. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions:

6.1    Term. Subject to the provisions of Section 5.2 regarding Ten Percent Shareholders, no Incentive Share Option shall be exercisable after the expiration of 10 years from the Grant Date. The term of a Non-qualified Share Option granted under the Plan shall be determined by the Committee; provided, however, no Non-qualified Share Option shall be exercisable after the expiration of 10 years from the Grant Date, and Non-qualified Share Options granted to persons who are not Employees (including Directors who are not Employees) shall not be exercisable after the expiration of five (5) years from the Grant Date.

6.2    Exercise Price of An Incentive Share Option. Subject to the provisions of Section 5.2 regarding Ten Percent Shareholders, the Option Exercise Price of each Incentive Share Option shall be not less than 100% of the Fair Market Value of an Ordinary Share subject to the Option on the Grant Date. Notwithstanding the foregoing, an Incentive Share Option may be granted with an Option Exercise Price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code.

6.3    Exercise Price of a Non-qualified Share Option. The Option Exercise Price of each Non-qualified Share Option shall be not less than 100% of the Fair Market Value of an Ordinary Share subject to the Option on the Grant Date. Notwithstanding the foregoing, a Non-qualified Share Option may be granted with an Option Exercise Price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 409A of the Code.

6.4    Consideration. The Option Exercise Price of an Ordinary Share acquired pursuant to an Option shall be paid, to the extent permitted by Applicable Laws, either (a) in cash or by certified or bank check at the time the Option is exercised; or (b) in the discretion of the Committee, upon such terms as the Committee shall approve, the Option Exercise Price may be paid: (i) by reduction in the number of Ordinary Shares otherwise deliverable upon exercise of such Option with a Fair Market Value equal to the aggregate Option Exercise Price at the time of exercise; (ii) in accordance with a cashless exercise program established with a securities brokerage firm, or (iii) in any other form of legal consideration that may be acceptable to the Committee.

6.5    Transferability of An Incentive Share Option. An Incentive Share Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

6.6    Transferability of a Non-qualified Share Option. A Non-qualified Share Option may, in the sole discretion of the Committee, be transferable for no consideration to a Permitted Transferee, upon written approval by the Committee to the extent provided in the Award Agreement. If the Non-qualified Share Option does not provide for transferability, then the Non-qualified Share Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

6.7    Vesting of Options. Each Option may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the

7

Committee may deem appropriate. The vesting provisions of individual Options may vary. No Option may be exercised for a fraction of an Ordinary Share. The Committee may, but shall not be required to, provide for an acceleration of vesting and exercisability in the terms of any Award Agreement upon the occurrence of a specified event.

6.8    Termination of Continuous Service. Unless otherwise provided in an Award Agreement or in an employment agreement the terms of which have been approved by the Committee, in the event an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within such period of time ending on the earlier of (a) the date three months following the termination of the Optionholder’s Continuous Service; or (b) the expiration of the term of the Option as set forth in the Award Agreement; provided that, if the termination of Continuous Service is by the Company for Cause, all outstanding Options (whether or not vested) shall immediately terminate and cease to be exercisable.

6.9    Extension of Termination Date. An Optionholder’s Award Agreement may also provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service for any reason would be prohibited at any time because the issuance of Ordinary Shares would violate the registration requirements under the Securities Act or any other Applicable Laws, then the Option shall terminate on the earlier of (a) the expiration of the term of the Option in accordance with Section 6.1; or (b) the expiration of a period after termination of the Participant’s Continuous Service that is three months after the end of the period during which the exercise of the Option would be in violation of such registration or other securities law requirements.

6.10    Disability of Optionholder. Unless otherwise provided in an Award Agreement, in the event that an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination), but only within such period of time ending on the earlier of (a) the date 12 months following such termination; or (b) the expiration of the term of the Option as set forth in the Award Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein or in the Award Agreement, the Option shall terminate.

6.11    Death of Optionholder. Unless otherwise provided in an Award Agreement, in the event an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death, but only within the period ending on the earlier of (a) the date 12 months following the date of death; or (b) the expiration of the term of such Option as set forth in the Award Agreement. If, after the Optionholder’s death, the Option is not exercised within the time specified herein or in the Award Agreement, the Option shall terminate.

6.12    Incentive Share Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of an Ordinary Share with respect to which Incentive Share Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and its Affiliates) exceeds U.S. $100,000, the Options or portions thereof which exceed such limit (according to the order in which they were granted in accordance with Section 422(d) of the Code) shall be treated as Non-qualified Share Options.

7.1    Share Appreciation Rights.

(a)    General. Each Share Appreciation Right granted under the Plan shall be evidenced by an Award Agreement. Each Share Appreciation Right so granted shall be subject to the conditions set forth in this Section 7.1,

8

and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. Share Appreciation Rights may be granted alone or in tandem with an Option granted under the Plan.

(b)    Grant Requirements. Any Share Appreciation Right that relates to a Non-qualified Share Option may be granted at the same time the Option is granted or at any time thereafter but before the exercise or expiration of the Option. Any Share Appreciation Right that relates to an Incentive Share Option must be granted at the same time the Incentive Share Option is granted.

(c)    Term of Share Appreciation Rights. The term of a Share Appreciation Right granted under the Plan shall be determined by the Committee; provided, however, no Share Appreciation Right shall be exercisable later than the tenth anniversary of the Grant Date.

(d)    Vesting of Share Appreciation Rights. Each Share Appreciation Right may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The Share Appreciation Right may be subject to such other terms and conditions on the time or times when it may be exercised as the Committee may deem appropriate. The vesting provisions of individual Share Appreciation Rights may vary. No Share Appreciation Right may be exercised for a fraction of an Ordinary Share. The Committee may, but shall not be required to, provide for an acceleration of vesting and exercisability in the terms of any Share Appreciation Right upon the occurrence of a specified event.

(e)    Exercise. Upon exercise of a Share Appreciation Right, the holder shall be entitled to receive from the Company an amount equal to the number of Ordinary Shares subject to the Share Appreciation Right that is being exercised multiplied by the excess of (i) the Fair Market Value of an Ordinary Share on the date the Award is exercised, over (ii) the exercise price specified in the Share Appreciation Right or related Option.

(f)    Exercise Price. The exercise price of a Share Appreciation Right shall be determined by the Committee, but shall not be less than 100% of the Fair Market Value of one Ordinary Share on the Grant Date of such Share Appreciation Right. Notwithstanding the foregoing, a Share Appreciation Right may be granted with an exercise price lower than that set forth in the preceding sentence if such Share Appreciation Right is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 409A of the Code. A Share Appreciation Right granted simultaneously with or subsequent to the grant of an Option and in conjunction therewith or in the alternative thereto shall have the same exercise price as the related Option, shall be transferable only upon the same terms and conditions as the related Option, and shall be exercisable only to the same extent as the related Option; provided, however, that a Share Appreciation Right, by its terms, shall be exercisable only when the Fair Market Value per Ordinary Share subject to the Share Appreciation Right and related Option exceeds the exercise price per share thereof and no Share Appreciation Rights may be granted in tandem with an Option unless the Committee determines that the requirements of Section 7.1(b) are satisfied.

7.2    Restricted Awards.

(a)    General. A Restricted Award is an Award of actual Ordinary Shares (“Restricted Share”) or hypothetical Ordinary Share units (“Restricted Share Units”) having a value equal to the Fair Market Value of an identical number of Ordinary Shares, which may, but need not, provide that such Restricted Award may not be sold, assigned, transferred or otherwise disposed of, pledged or hypothecated as collateral for a loan or as security for the performance of any obligation or for any other purpose for such period (the “Restricted Period”) as the Committee shall determine. Each Restricted Award granted under the Plan shall be evidenced by an Award Agreement. Each Restricted Award so granted shall be subject to the conditions set forth in this Section 7.2, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

9

(d)    Restricted Period. With respect to Restricted Awards, the Restricted Period shall commence on the Grant Date and end at the time or times set forth on a schedule established by the Committee in the applicable Award Agreement. No Restricted Award may be granted or settled for a fraction of an Ordinary Share. The Committee may, but shall not be required to, provide for an acceleration of vesting in the terms of any Award Agreement upon the occurrence of a specified event.

10

(e)    Delivery of Restricted Shares; Settlement of Restricted Share Units. Upon the expiration of the Restricted Period with respect to any Restricted Shares, the restrictions set forth in Section 7.2(c) and the applicable Award Agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award Agreement. If an escrow arrangement is used, upon such expiration, the Company shall deliver to the Participant, or his or her beneficiary, without charge, the share certificate evidencing the Restricted Shares which have not then been forfeited and with respect to which the Restricted Period has expired (to the nearest full share) and any cash dividends or share dividends credited to the Participant’s account with respect to such Restricted Shares and the interest thereon, if any. Upon the expiration of the Restricted Period with respect to any outstanding Restricted Share Units unless payment is further deferred in compliance with Applicable Laws including, but not limited to Section 409A of the Code, the Company shall deliver to the Participant, or his or her beneficiary, without charge, one Ordinary Share for each outstanding vested Restricted Share Unit and cash equal to any Dividend Equivalents credited with respect to each such vested Restricted Share Unit in accordance with Section 7.2(b)(ii) hereof and the interest thereon or, at the discretion of the Committee, in Ordinary Shares having a Fair Market Value equal to such Dividend Equivalents and the interest thereon, if any; provided, however, that, if explicitly provided in the applicable Award Agreement, the Committee may, in its sole discretion, elect to pay cash or part cash and part Ordinary Shares in lieu of delivering only Ordinary Shares for vested Restricted Share Units. If a cash payment is made in lieu of delivering Ordinary Shares, the amount of such payment shall be equal to the Fair Market Value of an Ordinary Share as of the date on which the Restricted Period lapsed in the case of Restricted Share Units.

(f)    Share Restrictions. Each certificate representing Restricted Share awarded under the Plan shall bear a legend in such form as the Company deems appropriate.

(g)     Performance Awards. Restricted Awards may be granted at the sole discretion of the Committee, with vesting conditions based on the attainment of written Performance Goals. The Committee shall determine the performance period and whether, with respect to a performance period, the applicable Performance Goals have been met with respect to a given Participant and, if they have, to so certify and ascertain the amount of the applicable Performance Award. No Performance Awards will be issued for such performance period until such certification is made by the Committee. The number Ordinary Shares issued in respect of a Performance Award to a given Participant may be less than the amount determined by the applicable Performance Goal formula, at the discretion of the Committee. The number of Ordinary Shares issued in respect of a Performance Award determined by the Committee for a performance period shall be paid to the Participant at such time as determined by the Committee in its sole discretion after the end of such performance period and any dividends (other than share dividends to be issued pursuant to Section 11) or Dividend Equivalents that accrue shall only be paid in respect of the number of Ordinary Shares earned in respect of a Performance Award.

8.    Securities Law Compliance. Each Award Agreement shall provide that no Ordinary Shares shall be purchased or sold thereunder unless and until (a) any then Applicable Laws have been fully complied with to the satisfaction of the Company and its counsel; and (b) if required to do so by the Company, the Participant has executed and delivered to the Company a letter of investment intent in such form and containing such provisions as the Committee may require. The Company shall use reasonable efforts to seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Awards and to issue and sell Ordinary Shares upon exercise of the Awards; provided, however, that this undertaking shall not require the Company to register the Ordinary Shares, the Plan or any Award under the Securities Act with the U.S Securities and Exchange Commission or with any state securities commission or stock exchange or under any other Applicable Laws. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Ordinary Shares under the Plan, the Company shall be relieved from any liability for failure to issue and sell Ordinary Shares upon exercise of such Awards unless and until such authority is obtained.

9.    Use of Proceeds from Shares. Proceeds from the sale of Ordinary Shares pursuant to Awards, or upon exercise thereof, shall constitute general funds of the Company.

11

10.    Miscellaneous.

10.1    Acceleration of Exercisability and Vesting. The Committee shall have the power to accelerate the time at which an Award may first be exercised or the time during which an Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Award stating the time at which it may first be exercised or the time during which it will vest.

10.2    Shareholder Rights. Except as provided in the Plan or an Award Agreement, no Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any Ordinary Shares subject to such Award unless and until such Participant has satisfied all requirements for exercise of the Award pursuant to its terms and no adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property) or distributions of other rights for which the record date is prior to the date such Ordinary Shares are issued, except as provided in Section 11 hereof. Any dividends or Dividend Equivalents shall in all events be subject to the same vesting and forfeiture restrictions as apply to the Award to which they relate.

10.3    No Employment or Other Service Rights. Nothing in the Plan or any instrument executed or Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or shall affect the right of the Company or an Affiliate to terminate (a) the employment of an Employee with or without notice and with or without Cause; or (b) the service of a Director pursuant to the Articles of Association of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.

10.4    Transfer; Approved Leave of Absence. For purposes of the Plan, no termination of employment by an Employee shall be deemed to result from either (a) a transfer of employment to the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another; or (b) 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 Committee otherwise so provides in writing, in either case, except to the extent inconsistent with Applicable Laws, including but not limited to Section 409A of the Code if the applicable Award is subject thereto.

10.5    Withholding Obligations. To the extent provided by the terms of an Award Agreement and subject to the discretion of the Committee, the Participant may satisfy any foreign, federal, state or local tax withholding obligation relating to the exercise or acquisition of Ordinary Shares under an Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (a) tendering a cash payment; (b) authorizing the Company to withhold Ordinary Shares from the Ordinary Shares otherwise issuable to the Participant as a result of the exercise or acquisition of Ordinary Shares under the Award, provided, however, that no Ordinary Shares are withheld with a value exceeding the maximum amount of tax required to be withheld by Applicable Laws; or (c) delivering to the Company previously owned and unencumbered Ordinary Shares of the Company.

11.    Adjustments Upon Changes in Shares. In the event of changes in the outstanding Ordinary Shares or in the capital structure of the Company by reason of any share or extraordinary cash dividend, share split, reverse share split, an extraordinary corporate transaction such as any recapitalization, reorganization, merger, consolidation, combination, exchange, or other relevant change in capitalization occurring after the Grant Date of any Award, Awards granted under the Plan and any Award Agreements, the exercise price of Options and Share Appreciation Rights, the maximum number of Ordinary Shares subject to all Awards stated in Section 4 will be equitably adjusted or substituted, as to the number, price or kind of an Ordinary Share or other consideration subject to such Awards to the extent necessary to preserve the economic intent of such Award. In the case of adjustments made pursuant to this Section 11, unless the Committee specifically determines that such adjustment is in the best interests of the Company or its Affiliates, the Committee shall, in the case of Incentive Share Options,

12

ensure that any adjustments under this Section 11 will not constitute a modification, extension or renewal of the Incentive Share Options within the meaning of Section 424(h)(3) of the Code and in the case of Non-qualified Share Options, ensure that any adjustments under this Section 11 will not constitute a modification of such Non-qualified Share Options within the meaning of Section 409A of the Code. The Company shall give each Participant notice of an adjustment hereunder and, upon notice, such adjustment shall be conclusive and binding for all purposes.

12.1    The obligations of the Company under the Plan and the Award Agreements shall be binding upon any successor corporation or organization resulting from the merger, consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to all or substantially all of the assets and business of the Company and its Affiliates, taken as a whole (a “Corporate Transaction”).

12.2    In the event of a Corporate Transaction, the Board may take one or more of the following actions with respect to Options and Share Appreciation Rights: (i) make appropriate provision for the continuation of the Option or Share Appreciation Right by substituting on an equitable basis for the Ordinary Shares then subject to such Option or Share Appreciation Right either the consideration payable with respect to the outstanding Ordinary Shares in connection with the Corporate Transaction or securities of any successor or acquiring entity; (ii) require that Participants surrender their outstanding Options or Share Appreciation Rights in exchange for a payment by the Company, in cash or Ordinary Shares as determined by the Board, in an amount equal to the amount by which the then Fair Market Value of the Ordinary Shares subject to such vested Option or Share Appreciation Right exceeds the Exercise Price; or (iii) after giving Participants an opportunity to exercise to the extent vested their outstanding Options or Share Appreciation Rights, terminate any or all unexercised Options and Share Appreciation Rights at such time as the Board deems appropriate. Such surrender or termination shall take place as of the date of the Corporate Transaction or such other date as the Board may specify.

12.3    In the event of a Corporate Transaction with respect to outstanding Restricted Awards, the Board, shall make appropriate provision for the continuation of such Restricted Awards on the same terms and conditions by substituting on an equitable basis for the Ordinary Shares then subject to such Restricted Awards either the consideration payable with respect to the outstanding Ordinary Shares in connection with the Corporate Transaction or securities of any successor or acquiring entity. In lieu of the foregoing, in connection with any Corporate Transaction, the Board may provide that, upon consummation of the Corporate Transaction, each outstanding Restricted Award shall be terminated in exchange for payment of an amount equal to the consideration payable upon consummation of such Corporate Transaction to a holder of the number of Ordinary Shares comprising such Restricted Award to then extent then vested.

13.1    Amendment of Plan. The Board at any time, and from time to time, may amend or terminate the Plan. However, except as provided in Section 11 relating to adjustments upon changes in Ordinary Shares and Section 13.3, no amendment shall be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary to satisfy any Applicable Laws. At the time of such amendment, the Board shall determine, upon advice from counsel, whether such amendment will be contingent on shareholder approval.

13.2    Shareholder Approval. The Board will, submit any amendment to the Plan for shareholder approval if required under Applicable Laws. Other than as set forth in Section 12 of the Plan, the Board may not without shareholder approval reduce the exercise price of a share option or share appreciation right or cancel any outstanding Share Option or Share Appreciation Right Award in exchange for a replacement Award having a lower exercise price, any other Award or for cash. In addition, the Board shall not take any other action that is considered a direct or indirect “repricing” for purposes of the shareholder approval rules of the applicable securities exchange or inter-dealer quotation system on which the Ordinary Shares are listed, including any other action that is treated as a repricing under generally accepted accounting principles.

13

13.3    Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees, Consultants and Directors with the maximum benefits provided or to be provided under the provisions of the Code relating to Incentive Share Options or to the nonqualified deferred compensation provisions of Section 409A of the Code and/or to bring the Plan and/or Awards granted under it into compliance therewith.

13.4    No Impairment of Rights. Rights under any Award granted before amendment of the Plan shall not adversely affect the Participant’s material rights by any amendment of the Plan unless (a) the Company requests the consent of the Participant; and (b) the Participant consents in writing.

13.5    Amendment of Awards. The Committee at any time, and from time to time, may amend the terms of any one or more Awards; provided, however, that the Committee may not affect any amendment which would adversely affect the Participant’s material rights under any Award unless (a) the Company requests the consent of the Participant; and (b) the Participant consents in writing.

14.1    Other Compensation Arrangements. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, subject to shareholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases.

14.2    Unfunded Plan. The Plan shall be unfunded. Neither the Company, the Board nor the Committee shall be required to establish any special or separate fund or to segregate any assets to assure the performance of its obligations under the Plan.

14.3    Recapitalizations and Reorganizations. Each Award Agreement shall contain provisions required to reflect the provisions of Sections 11 and 12.

14.4    Delivery. Upon exercise of a right granted under this Plan, the Company shall issue Ordinary Shares or pay any amounts due within a reasonable period of time thereafter. Subject to any statutory or regulatory obligations the Company may otherwise have, for purposes of this Plan, 30 days shall be considered a reasonable period of time.

14.5    No Fractional Shares. No fractional Ordinary Shares shall be issued or delivered pursuant to the Plan. The Committee shall determine whether cash, additional Awards or other securities or property shall be issued or paid in lieu of fractional Ordinary Shares or whether any fractional shares should be rounded, forfeited or otherwise eliminated.

14.6    Other Provisions. The Award Agreements authorized under the Plan may contain such other provisions not inconsistent with this Plan, including, without limitation, restrictions upon the exercise of the Awards, as the Committee may deem advisable.

14.7    Section 409A. The Plan is intended to comply with Section 409A of the Code to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and administered to be in compliance therewith. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless Applicable Laws require otherwise. Notwithstanding anything to the contrary in the Plan, to the extent required to avoid accelerated taxation and tax penalties under Section 409A of the Code, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to the Plan during the 6 month period immediately following the Participant’s termination of Continuous Service shall instead be paid on the first payroll date after the 6 month anniversary of the Participant’s separation from service (or the Participant’s death, if earlier). Notwithstanding the foregoing, neither the Company nor the Committee shall have any obligation to take any

14

action to prevent the assessment of any excise tax or penalty on any Participant under Section 409A of the Code and neither the Company nor the Committee will have any liability to any Participant for such tax or penalty.

14.8    Disqualifying Dispositions. Any Participant who shall make a “disposition” (as defined in Section 424 of the Code) of all or any portion of Ordinary Shares acquired upon exercise of an Incentive Share Option within two years from the Grant Date of such Incentive Share Option or within one year after the issuance of the Ordinary Shares acquired upon exercise of such Incentive Share Option (a “Disqualifying Disposition”) shall be required if requested by the Company to immediately advise the Company in writing as to the occurrence of the sale and the price realized upon the sale of such Ordinary Shares.

14.9    Section 16. It is the intent of the Company that the Plan satisfy, and be interpreted in a manner that satisfies, the applicable requirements of Rule 16b-3 as promulgated under Section 16 of the Exchange Act so that Participants will be entitled to the benefit of Rule 16b-3, or any other rule promulgated under Section 16 of the Exchange Act, and will not be subject to short-swing liability under Section 16 of the Exchange Act. Accordingly, if the operation of any provision of the Plan would conflict with the intent expressed in this Section 14.9 such provision to the extent possible shall be interpreted and/or deemed amended so as to avoid such conflict.

14.10    Beneficiary Designation. Each Participant under the Plan may from time to time name any beneficiary or beneficiaries by whom any right under the Plan is to be exercised in case of such Participant’s death. Each designation will revoke all prior designations by the same Participant, shall be in a form reasonably prescribed by the Committee and shall be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime.

14.11    Expenses. The costs of administering the Plan shall be paid by the Company.

14.12    Severability. If any of the provisions of the Plan or any Award Agreement is held to be invalid, illegal or unenforceable, whether in whole or in part, such provision shall be deemed modified to the extent, but only to the extent, of such invalidity, illegality or unenforceability and the remaining provisions shall not be affected thereby.

14.13    Plan Headings. The headings in the Plan are for purposes of convenience only and are not intended to define or limit the construction of the provisions hereof.

14.14    Non-Uniform Treatment. The Committee’s determinations under the Plan need not be uniform and may be made by it selectively among persons who are eligible to receive, or actually receive, Awards. Without limiting the generality of the foregoing, the Committee shall be entitled to make non-uniform and selective determinations, amendments and adjustments, and to enter into non-uniform and selective Award Agreements.

15.    Effective Date and Termination or Suspension of Plan. The Plan shall become effective as of the Effective Date and shall terminate at the earliest of (a) such time as no Shares remain available for issuance under the Plan, (b) termination of the Plan by the Board, or (c) the tenth anniversary of the Effective Date. Awards outstanding upon expiration of the Plan shall remain in effect until they have been exercised or terminated, or have expired. No grants of Incentive Stock Options may be made under the Plan on or after June 15, 2031. The Board may suspend or terminate the Plan at any earlier date pursuant to Section 13.1 hereof. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated.

16.    Choice of Law. The applicable laws of the State of Delaware, United States of America shall govern all questions concerning the construction, validity and interpretation of this Plan unless this Plan so specifies the interpretation of other Applicable Laws then, in such case, those Applicable Laws shall govern.

15

17.    Clawback. Notwithstanding anything to the contrary contained in this Plan, the Company may recover from a Participant any compensation received from any Award (whether or not vested or settled) or cause a Participant to forfeit any Award (whether or not vested) in the event that the Company’s Clawback Policy then in effect is triggered.
