SECTION 1.
	
GENERAL PURPOSE OF THE PLAN; DEFINITIONS




The name of the plan is the Alkermes plc 2018 Stock Option and Incentive Plan (the “Plan”).

It is anticipated that providing such persons with a direct stake in the Company's welfare will assure a closer alignment of their interests with those of the Company and its shareholders, thereby stimulating their efforts on the Company's and its Subsidiaries' behalf and strengthening their desire to remain with the Company and its Subsidiaries.

(a)Administration of Plan.    The Plan shall be administered by the Administrator.

(b)Powers of Administrator.    The Administrator shall have the power and authority to grant Awards consistent with the terms of the Plan, including the power and authority:

(i)to select the individuals to whom Awards may from time to time be granted;

(ii)to determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Non-Qualified Stock Options, Stock Appreciation Rights, Restricted Stock Awards, 



Restricted Stock Unit Awards, Cash-Based Awards and Performance Share Awards, or any combination of the foregoing, granted to any one or more grantees;

(iii)to determine the number of Shares to be covered by any Award;

(iv)to determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, which terms and conditions may differ among individual Awards and grantees, and to approve the form of written (or electronic) instruments evidencing the Awards;

(v)subject to the provisions of Sections 5(a)(iii), 6(d) and 7(a), to accelerate at any time the exercisability or vesting of all or any portion of any Award;

(vi)subject to the provisions of Section 5(a)(ii), to extend at any time the period in which Stock Options or Stock Appreciation Rights may be exercised; and

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company, Subsidiaries and Plan grantees.

(c)Delegation of Authority to Grant Awards.    Subject to applicable law, the Administrator, in its discretion, may delegate to a subcommittee comprised of one or more members of the Board all or part of the Administrator's authority and duties with respect to the granting of Awards to employees who are not subject to the reporting and other provisions of Section 16 of the Exchange Act. Any such delegation by the Administrator shall include a limitation as to the amount of the Awards that may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price, in the case of Stock Options and Stock Appreciation Rights, and the vesting criteria for the Award. The Administrator may revoke or amend the terms of a delegation at any time, but such action shall not invalidate any prior actions of the Administrator's delegate or delegates that were consistent with the terms of the Plan.

(d)Award Certificates.    Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations for each Award which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service terminates.

(e)Indemnification.    Subject to Section 235 of the Companies Act, neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys' fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company's articles or bylaws or any directors' and officers' liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between such individual and the Company.

(f)Foreign Award Recipients.    Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws in other countries in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the power and authority to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the 



extent the Administrator determines such actions to be necessary or advisable (and such subplans and/or modifications shall be attached to the Plan as appendices); provided, however, that no such subplans and/or modifications shall increase the Share limitations contained in Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or any other applicable United States governing statute or law.


	
SECTION 3.
	
SHARES ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION    




(a)Shares Issuable.    The maximum number of Shares reserved and available for issuance under the Plan shall be equal to the sum of: (i) 27,600,000 Shares; (ii) 1,199,965 Shares, which is the number of 2011 Plan Available Shares; and (iii) the Prior Plans Returning Shares, as such Shares become available from time to time. For purposes of this limitation, the Shares underlying any Awards that are forfeited, canceled, repurchased or otherwise terminated (other than by exercise) shall be added back to the number of Shares available for issuance under the Plan. Shares tendered or held back upon exercise of an Option or Stock Appreciation Right or settlement of an Award to cover the exercise price or tax withholding shall not be added back to the number of Shares available for issuance under the Plan. In addition, upon net exercise of Options, the gross number of Shares exercised shall be deducted from the total number of Shares available for issuance under the Plan. Shares purchased in the open market with proceeds from the exercise of Options and Stock Appreciation Rights shall not be added to the number of Shares available for issuance under the Plan. In the event that a Stock Appreciation Right is settled in Shares, the gross number of Shares subject to the Stock Appreciation Right shall be deducted from the total number of Shares available for issuance under the Plan. Subject to such overall limitations, Shares may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that no more than 37,600,000 Shares may be issued in the form of Incentive Stock Options. The Shares issued under the Plan may be issued from treasury or otherwise.

(b)Effect of Awards.    The grant of any full value Award (i.e., an Award other than an Option or Stock Appreciation Right) shall be deemed, for purposes of determining the number of Shares available for issuance under Section 3(a), as an Award of 1.8 Shares for each such Share actually subject to the Award and shall be treated similarly if added back to the number of Shares available for issuance when forfeited, canceled, repurchased or otherwise terminated as provided in Section 3(a). Any Prior Plans Returning Share subject to a full value award (i.e., an award other than a stock option or stock appreciation right with respect to which the exercise price is at least 100% of the fair market value of the shares subject to such stock option or stock appreciation right on the date of grant) shall be added to the number of Shares available for issuance under Section 3(a) as 1.8 Shares. The grant of an Option or Stock Appreciation Right shall be deemed, for purposes of determining the number of Shares available for issuance under Section 3(a), as an Award for one Share for each such Share actually subject to the Award and shall be treated similarly if added back to the number of Shares available for issuance when forfeited, canceled, repurchased or otherwise terminated as provided in Section 3(a). Any Prior Plans Returning Share subject to a stock option or stock appreciation right with respect to which the exercise price is at least 100% of the fair market value of the shares subject to such stock option or stock appreciation right on the date of grant shall be added to the number of Shares available for issuance under Section 3(a) as one Share.

(c)Changes in Shares.    Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, share dividend, share split, reverse share split or other similar change in the Company's capital shares, the outstanding Shares are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such Shares or other securities, or, if, as a result of any merger or consolidation, or sale of all or substantially all of the assets of the Company, the outstanding Shares are converted into or exchanged for securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of Shares reserved for issuance under the Plan, including the maximum number of Shares that may be issued in the form of 



Incentive Stock Options, (ii) the number and kind of Shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per Share subject to each outstanding Restricted Stock Award, and (iv) the price for each Share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Shares subject to the Stock Option or Stock Appreciation Right) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of Shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall be final, binding and conclusive. No fractional Shares shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional Shares.

(d)Mergers and Other Transactions.    Except as the Administrator may otherwise specify with respect to particular Awards in the relevant Award documentation, in the case of and subject to the consummation of a Sale Event, all Options and Stock Appreciation Rights that are not exercisable immediately prior to the effective time of the Sale Event shall become fully exercisable as of the effective time of the Sale Event, all other Awards with time-based vesting, conditions or restrictions shall become fully vested and nonforfeitable as of the effective time of the Sale Event and all other Awards with conditions and restrictions relating to the attainment of performance goals may become vested and nonforfeitable in connection with a Sale Event in the Administrator's discretion. Upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall terminate, unless provision is made in connection with the Sale Event in the sole discretion of the parties thereto for the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree (after taking into account any acceleration hereunder). In the event of such termination, the Company shall make or provide for a cash payment to the grantees holding Options or Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of Shares subject to outstanding Options or Stock Appreciation Rights (to the extent then exercisable (after taking into account any acceleration hereunder) at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options or Stock Appreciation Rights.

(e)Substitute Awards.    The Administrator may grant Awards under the Plan in substitution for stock and stock-based awards held by employees, directors or consultants of another corporation in connection with the merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the substitute awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances. Any substitute Awards granted under the Plan shall not count against the Share limitation set forth in Section 3(a).


	
SECTION 4.
	
ELIGIBILITY    




Grantees under the Plan will be such full or part-time officers and other employees, Non-Employee Directors and consultants of the Company and its Subsidiaries as are selected from time to time by the Administrator in its sole discretion.


	
SECTION 5.
	
STOCK OPTIONS AND STOCK APPRECIATION RIGHTS    




Any Stock Option or Stock Appreciation Right granted under the Plan shall be in such form as the Administrator may from time to time approve.

Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option.



(a)Grant of Stock Options and Stock Appreciation Rights.    The Administrator in its discretion may grant Stock Options and Stock Appreciation Rights to eligible employees, Non-Employee Directors, and consultants of the Company or any Subsidiary. Stock Options and Stock Appreciation Rights granted pursuant to this Section 5(a) shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. If the Administrator so determines, Stock Options and Stock Appreciation Rights may be granted in lieu of cash compensation at the grantee's election, subject to such terms and conditions as the Administrator may establish. Each Stock Appreciation Right will be denominated in Share equivalents.

(i)Exercise Price.    The exercise price per Share covered by a Stock Option or Stock Appreciation Right granted pursuant to this Section 5(a) shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the exercise price per Share of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date.

(ii)Term and Termination.    The term of each Stock Option and Stock Appreciation Right shall be fixed by the Administrator, but no Stock Option or Stock Appreciation Right shall be exercisable more than ten years after the date the Stock Option or Stock Appreciation Right is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option shall be no more than five years from the date of grant. Unless otherwise determined by the Administrator on or after the date of grant, if a grantee's employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason (including if a Subsidiary ceases to be a Subsidiary of the Company), the portion of each Stock Option and Stock Appreciation Right held by the grantee that is not then exercisable shall be immediately forfeited. Unless otherwise determined by the Administrator on or after the date of grant, the grantee may exercise the exercisable portion of his Stock Options and Stock Appreciation Rights until the earlier of three months after such date of termination or the expiration of the stated term of such Stock Option or Stock Appreciation Right.

(iii)Exercisability; Rights of a Shareholder.    Stock Options and Stock Appreciation Rights shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date, provided they shall not be exercisable for a period of not less than one year from the date of grant. A grantee shall have the rights of a shareholder only as to Shares acquired upon the exercise of a Stock Option or Stock Appreciation Right and not as to unexercised Stock Options or Stock Appreciation Rights. The Administrator may accelerate vesting during the minimum vesting period only in the case of a grantee's death, Disability or retirement or upon a Sale Event, and otherwise may accelerate the vesting of all or any portion of any Stock Option or Stock Appreciation Right at any time.

(iv)Method of Exercise for Stock Options.    Stock Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company's delegate, specifying the number of Shares to be purchased. In the case of a Stock Option that is not an Incentive Stock Option, unless otherwise determined by the Administrator on or after the date of grant, payment of the purchase price must be made by reduction in the number of Shares issuable upon such exercise, based, in each case, on the Fair Market Value of the Shares on the date of exercise. If the Administrator determines not to use the above payment method or in the case of the exercise of Incentive Stock Options, then payment of the purchase price may be made by one or more of the following methods:

(A)In cash, by certified or bank check or other instrument acceptable to the Administrator;

(B)Subject to the consent of the Administrator and on the basis of such form of surrender agreement as the Administrator may specify, through the delivery (or attestation 



to the ownership) of Shares owned by the optionee. Such surrendered Shares shall be valued at Fair Market Value on the exercise date; or

(C)By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure.

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the Shares to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such Shares and the fulfillment of any other requirements contained in the Option Award Certificate or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned Shares through the attestation method, the number of Shares transferred to the optionee upon the exercise of the Stock Option shall be net of the number of attested Shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use of such an automated system.

(v)Method of Exercise for Stock Appreciation Rights and Payment upon Exercise.    Stock Appreciation Rights may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company's delegate, specifying the number of Shares to be exercised. The appreciation distribution payable on the exercise of a Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of exercise of the Stock Appreciation Right) of a number of Shares equal to the number of Share equivalents in which the grantee is vested under the Stock Appreciation Right, and with respect to which the grantee is exercising the Stock Appreciation Right on such date, over (B) the aggregate exercise price of the number of Share equivalents with respect to which the grantee is exercising the Stock Appreciation Right on such date. The appreciation distribution may be paid in Shares, in cash, in any combination of the two or in any other form of consideration, as determined by the Administrator and contained in the Stock Appreciation Right Award Certificate.

(vi)Annual Limit on Incentive Stock Options.    To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the Shares with respect to which Incentive Stock Options granted under the Plan and any other plan of the Company or its subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option.


	
SECTION 6.
	
RESTRICTED STOCK AWARDS




(a)Nature of Restricted Stock Awards.    The Administrator shall determine the restrictions and conditions applicable to each Restricted Stock Award at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The terms and conditions of each Restricted Stock Award Certificate shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

(b)Rights as a Shareholder.    Upon the grant of a Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a shareholder with respect to the voting of 



the Shares subject to the Restricted Stock Award and receipt of dividends (if any), subject to such conditions contained in the Restricted Stock Award Certificate. Unless the Administrator shall otherwise determine, (i) uncertificated Shares subject to the Restricted Stock Award shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture until such Shares are vested as provided in Section 6(d) below, and (ii) certificated Shares subject to the Restricted Stock Award shall remain in the possession of the Company until such Shares are vested as provided in Section 6(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe. Notwithstanding anything herein to the contrary, any dividends paid by the Company during the vesting period of any Restricted Stock Award shall accrue and shall not be paid until the Shares subject to the Restricted Stock Award have vested and if any such Shares are forfeited, the grantee shall have no rights to any such accrued dividends.

(c)Restrictions.    Shares subject to a Restricted Stock Award may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award Certificate. If a grantee's employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason (including if a Subsidiary ceases to be a Subsidiary of the Company), any Shares subject to a Restricted Stock Award that have not vested at the time of termination shall automatically, without any requirement of notice to such grantee from, or other action by or on behalf of, the Company or its Subsidiaries, be deemed to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee's legal representative simultaneously with such termination of employment (or other service relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a shareholder. Following such deemed reacquisition of unvested Shares subject to a Restricted Stock Award that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration.

(d)Vesting of Restricted Stock Awards.    The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock Award and the Company's right of repurchase or forfeiture shall lapse. Notwithstanding the foregoing, the restriction period with respect to Restricted Stock Awards shall not be less than one year. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the Shares on which all restrictions have lapsed shall no longer be subject to the Restricted Stock Award and shall be deemed “vested”. Except as may otherwise be provided by the Administrator pursuant to the authority reserved in this Section 6, a grantee's rights in any Shares subject to a Restricted Stock Award that have not vested shall automatically terminate upon the grantee's termination of employment (or other service relationship) with the Company and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Company) and such Shares shall be subject to the provisions of Section 6(c) above. The Administrator may accelerate vesting during the minimum vesting period only in the case of a grantee's death, Disability or retirement or upon a Sale Event, and otherwise may accelerate the vesting of all or any portion of any Restricted Stock Award at any time.


	
SECTION 7.
	
RESTRICTED STOCK UNIT AWARDS    




(a)Nature of Restricted Stock Unit Awards.    The Administrator shall determine the restrictions and conditions applicable to each Restricted Stock Unit Award at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The terms and conditions of each Restricted Stock Unit Award Certificate shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. Notwithstanding the foregoing, the restriction period with respect to such Restricted Stock Unit Awards shall not be less than one year. At the end of the restriction period, the Restricted Stock Unit Award, to the extent vested, shall be settled in the form of Shares. To the extent that a Restricted Stock Unit Award is subject to Section 409A, it may contain such additional terms and conditions as the Administrator shall determine in its sole discretion in order for such Award to comply with the requirements of Section 409A. The Administrator may accelerate vesting during the minimum 



vesting period only in the case of a grantee's death, Disability or retirement or upon a Sale Event, and otherwise may accelerate the vesting of all or any portion of any Restricted Stock Unit Award at any time.

(b)Election to Receive Restricted Stock Unit Awards in Lieu of Compensation.    The Administrator may, in its sole discretion, permit a grantee to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of a Restricted Stock Unit Award. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures established by the Administrator. Any such future cash compensation that the grantee elects to defer shall be converted to a fixed number of phantom stock units (which may be fully vested) based on the Fair Market Value of the Shares on the date the compensation would otherwise have been paid to the grantee if such payment had not been deferred as provided herein. The Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate.

(c)Rights as a Shareholder.    A grantee shall have the rights as a shareholder only as to Shares acquired by the grantee upon settlement of a Restricted Stock Unit Award; provided, however, that the grantee may be credited with dividend equivalent rights with respect to the phantom stock units underlying his Restricted Stock Unit Award, subject to such terms and conditions as the Administrator may determine; provided that no payment of any such dividend equivalents shall be made unless and until such Restricted Stock Unit Award has vested, and if such Restricted Stock Unit Award is forfeited, the grantee shall have no right to such dividend equivalents.

(d)Termination.    Except as may otherwise be provided by the Administrator pursuant to the authority reserved in Section 7(a), a grantee's right in all Restricted Stock Unit Awards that have not vested shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Company).


	
SECTION 8.
	
CASH-BASED AWARDS    




Grant of Cash-Based Awards.    The Administrator may, in its sole discretion, grant Cash-Based Awards to any grantee in such number or amount and upon such terms, and subject to such conditions, as the Administrator shall determine at the time of grant. The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or payable, and such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of the Award and may be made in cash or in Shares, as the Administrator determines. Except as may otherwise be provided by the Administrator pursuant to the authority reserved in this Section 8, a grantee's right in all Cash-Based Awards that have not vested shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Company).


	
SECTION 9.
	
PERFORMANCE SHARE AWARDS    




(a)Nature of Performance Share Awards.    The Administrator may, in its sole discretion, grant Performance Share Awards independent of, or in connection with, the granting of any other Award under the Plan. The Administrator shall determine whether and to whom Performance Share Awards shall be granted, the Performance Goals, the Performance Cycles (which, as defined above, shall not be less than 12 months), and such other limitations and conditions as the Administrator shall determine.

(b)Rights as a Shareholder.    A grantee receiving a Performance Share Award shall have the rights of a shareholder only as to Shares actually received by the grantee under the Plan and not with respect to Shares subject to the Award but not actually received by the grantee. A grantee shall be entitled to receive Shares under a Performance Share Award only upon satisfaction of all conditions specified in the Performance Share Award Certificate (or in a performance plan adopted by the Administrator).



(c)Termination.    Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 15 below, in writing after the Award Certificate is issued, a grantee's rights in all Performance Share Awards shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Company).


	
SECTION 10.
	
PERFORMANCE-BASED AWARDS   




(a)Performance-Based Awards.    Any grantee who is selected by the Administrator may be granted one or more Performance-Based Awards payable upon the attainment of Performance Goals that are established by the Administrator and relate to one or more of the Performance Criteria, in each case on a specified date or dates or over any period or periods determined by the Administrator (which, for clarification, shall not be less than 12 months). The Administrator shall define the manner of calculating the Performance Criteria it selects to use for any Performance Cycle (which, as defined above, shall not be less than 12 months). Depending on the Performance Criteria used to establish such Performance Goals, the Performance Goals may be expressed in terms of overall performance of the Company or the performance of a Subsidiary, division, business unit, or an individual. The Administrator, in its discretion, may adjust or modify the calculation of Performance Goals for such Performance Cycle to make adjustments deemed appropriate by the Administrator, including but not limited to, in order to prevent the dilution or enlargement of the rights of an individual (i) in the event of, or in anticipation of, any unusual or extraordinary corporate item, transaction, event or development, (ii) in recognition of, or in anticipation of, any other unusual or nonrecurring events affecting the Company or its Subsidiaries, or the financial statements of the Company or its Subsidiaries, or (iii) in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles, or business conditions. Each Performance-Based Award shall comply with the provisions set forth below.

(b)Grant of Performance-Based Awards.    With respect to each Performance-Based Award granted to a grantee, the Administrator shall select the Performance Criteria for such grant and the Performance Goals with respect to each Performance Criterion (including a threshold level of performance below which no amount will become payable with respect to such Award). Each Performance-Based Award will specify the amount payable, or the formula for determining the amount payable, upon achievement of the various applicable performance targets. The Performance Criteria established by the Administrator may be (but need not be) different for each Performance Cycle and different Performance Goals may be applicable to Performance-Based Awards to different grantees.

(c)Payment of Performance-Based Awards.    Following the completion of a Performance Cycle, the Administrator shall meet to review and certify in writing whether, and to what extent, the Performance Goals for the Performance Cycle have been achieved and, if so, to also calculate and certify in writing the amount of the Performance-Based Awards earned for the Performance Cycle. The Administrator shall then determine the actual size of each grantee's Performance-Based Award, and, in doing so, may reduce or eliminate the amount of the Performance-Based Award for a grantee if, in its sole judgment, such reduction or elimination is appropriate.


	
SECTION 11.
	
TRANSFERABILITY OF AWARDS    




(a)Transferability.    Except as provided in Section 11(b) below, during a grantee's lifetime, his or her Awards shall be exercisable only by the grantee, or by the grantee's legal representative or guardian in the event of the grantee's incapacity. No Awards shall be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.

(b)Administrator Action.    Notwithstanding Section 11(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Stock Options and Stock Appreciation Rights to his or her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the 



transferee agrees in writing with the Company to be bound by all of the terms and conditions of the Plan and the applicable Award.

(c)Family Member.    For purposes of Section 11(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the grantee's household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50 percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons (or the grantee) own more than 50 percent of the voting interests.

(d)Designation of Beneficiary.    Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee's death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee's estate.


	
SECTION 12.
	
TAX WITHHOLDING    




(a)Payment by Grantee.    Each grantee shall pay to the Company or its Subsidiaries, or make arrangements satisfactory to the Administrator regarding payment of, any U.S. federal, state or local taxes, and non-U.S. or other taxes of any kind required by law to be withheld by the Company or its Subsidiaries with respect to any Award. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company's obligation to deliver evidence of book entry (or share certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee.

(b)Payment in Shares.    In connection with its obligations to withhold any U.S. federal, state or local taxes, and non-U.S. or other taxes from amounts paid to grantees, the Company or its Subsidiaries may make any arrangements that are consistent with the Plan as it may deem appropriate. Without limitation of the preceding sentence, the Company shall have the right to reduce the number of Shares otherwise required to be issued to a grantee (or other recipient) in an amount that would have a Fair Market Value on the date of such issuance equal to all such taxes as shall be required to be withheld by the Company or its Subsidiaries pursuant to any statute or other governmental regulation or ruling and paid to any U.S. federal, state or local, or non-U.S. taxing authority.


	
SECTION 13.
	
SECTION 409A AWARDS.    




To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the grantee's separation from service, or (ii) the grantee's death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any such Award may not be accelerated except to the extent permitted by Section 409A.


	
SECTION 14.
	
TRANSFER, LEAVE OF ABSENCE, ETC.    




For purposes of the Plan, the following events shall not be deemed a termination of employment:

(a)a transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another;



(b)an approved leave of absence for military service or sickness, or for any other purpose approved by the Company or its Subsidiaries, as the case may be, if the employee's right to re-employment 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 so provides in writing; or


	
 
	
(c)
	
the transfer in status from one eligibility category under Section 4 hereof to another category.





	
SECTION 15.
	
AMENDMENTS AND TERMINATION    




The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder's consent. Except as provided in Section 3(c) or 3(d), without prior shareholder approval, in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights, or effect repricing through cancellation and re-grants or cancellation in exchange for cash or another Award. To the extent required under the rules of any securities exchange or market system on which the Shares are listed or any other applicable rules, or to the extent approval by shareholders is determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code, Plan amendments shall be subject to approval by the shareholders of the Company entitled to vote at a meeting of shareholders. Nothing in this Section 15 shall limit the Administrator's authority to take any action permitted pursuant to Section 3(d).


	
SECTION 16.
	
STATUS OF PLAN    




With respect to the portion of any Award that has not been exercised and any payments in cash, Shares or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company's obligations to deliver Shares or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence.


	
SECTION 17.
	
GENERAL PROVISIONS    




(a)No Distribution.    The Administrator may require each person acquiring Shares pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the Shares without a view to distribution thereof.

(b)Delivery of Share Certificates.    Share certificates to grantees under the Plan shall be deemed delivered for all purposes when the Company or a share transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee's last known address on file with the Company. Uncertificated Shares shall be deemed delivered for all purposes when the Company or a share transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee's last known address on file with the Company or any Subsidiary, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records). Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing Shares pursuant to the exercise of any Award, unless and until the Administrator has determined, with advice of counsel (to the extent the Administrator deems such advice necessary or advisable), that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the Shares are listed, quoted or traded. All share certificates delivered pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with any U.S. federal, state or local or non-U.S. jurisdiction, securities or other laws, rules and quotation system on which the Shares are listed, quoted or traded. The Administrator may place legends on any share certificate to reference restrictions applicable to the Shares. In addition to the terms and conditions provided herein, the Administrator may require that an individual make such reasonable covenants, agreements, and 



representations as the Administrator, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator.

(c)Shareholder Rights.    Until Shares are deemed delivered in accordance with Section 17(b), no right to vote or receive dividends or any other rights of a shareholder will exist with respect to Shares to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or Stock Appreciation Right or any other action by the grantee with respect to an Award; provided further that, to the extent the terms of any Award provide for the accrual of dividends, in no event shall any such dividends be paid until such Award has vested.

(d)Other Compensation Arrangements; No Employment Rights.    Nothing contained in the Plan shall prevent the Board from adopting other or additional compensation plans or arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of the Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary.

(e)Trading Policy Restrictions.    Option and Stock Appreciation Right exercises and other Awards under the Plan shall be subject to the Company's insider trading policies and procedures, as in effect from time to time.

(f)Forfeiture of Awards.    The Awards granted hereunder to the executive officers of the Company are subject to the clawback policy of the Company in effect from time to time.

(g)Section 82 and Section 1043 of the Companies Act.    The Company and any Subsidiary incorporated in Ireland may do all such things as are contemplated by the Plan except to the extent that they are prohibited by Section 82 and Section 1043 of the Companies Act. Nothing in this Section 17(g) shall prohibit anything which may be done as contemplated by the Plan by a Subsidiary which is incorporated outside of Ireland.


	
SECTION 18.
	
EFFECTIVE DATE OF PLAN    




The Plan was approved by the Board on March 29, 2018. The Plan became effective upon approval by the holders of a majority of the votes cast at the 2018 Annual General Meeting of Shareholders of the Company. No grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date that the Plan was approved by the Board.


	
SECTION 19.
	
GOVERNING LAW    




This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the Commonwealth of Massachusetts, applied without regard to conflict of law principles.


	
SECTION 20.
	
DISPUTE RESOLUTION    




All disputes and differences arising out of the Plan or otherwise in connection therewith may be referred by the Company to arbitration pursuant to the procedures set forth in the applicable grant agreement of any grantee so affected.
