ALKERMES plc

2011 Stock Option and Incentive Plan

SECTION 1.GENERAL PURPOSE OF THE PLAN; DEFINITIONS    

        The name of the plan is the Alkermes plc 2011 Stock Option and Incentive Plan (the "Plan"). The Plan is established in connection with a business combination transaction pursuant to which Alkermes, Inc. (the " Company ") would become a wholly owned subsidiary of a new holding company to be named Alkermes plc, an Irish public limited company (the " Parent "). The purpose of the Plan is to encourage and enable the officers, employees, Non-Employee Directors and other key persons (including consultants and prospective employees) of the Parent and its Subsidiaries upon whose judgment, initiative and efforts the Parent and its Subsidiaries largely depend for the successful conduct of their business to acquire a proprietary interest in the Parent. It is anticipated that providing such persons with a direct stake in the Parent's welfare will assure a closer identification of their interests with those of the Parent and its stockholders, thereby stimulating their efforts on the Parent's and its Subsidiaries' behalf and strengthening their desire to remain with the Parent and its Subsidiaries.

SECTION 2.ADMINISTRATION OF PLAN; ADMINISTRATOR AUTHORITY TO SELECT GRANTEES AND DETERMINE AWARDS    

        (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, 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 of Stock 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 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 may be exercised; and

(vii)  at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written and electronic instruments); to make all determinations it deems advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan.

        All decisions and interpretations of the Administrator shall be binding on all persons, including the Parent, 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 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 Parent 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 Parent'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 Parent.

        (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 Parent 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.STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION    

        (a)    Stock Issuable.    

(i)  The maximum number of shares of Stock reserved and available for issuance under the Plan shall be equal to (i) 28,649,500 ordinary shares, plus (ii) the number of shares of Stock underlying any grants under the Plan that are forfeited, canceled, repurchased or terminated (other than by exercise) from and after the date the Plan is approved by shareholders. For purposes of this limitation, the shares of Stock underlying any Awards that are forfeited, canceled or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan. Shares tendered or held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding shall not be available for future 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 remaining available for issuance under the Plan. Shares purchased in the open market with proceeds from the exercise of Options shall not be available for future issuance under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that Stock Options with respect to no more than 4,000,000 shares of Stock may be granted to any one individual grantee during any one calendar year period and no more than 28,649,500 shares of the Stock may be issued in the form of Incentive Stock Options. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Parent.

        (b)    Effect of Awards.    The grant of any full value Award (i.e., an Award other than an Option) shall be deemed, for purposes of determining the number of shares of Stock available for issuance under Section 3(a)(i), as an Award of 1.8 shares of Stock for each such share of Stock actually subject to the Award and shall be treated similarly if returned to reserve status when forfeited or canceled as provided in Section 3(a). The grant of an Option shall be deemed, for purposes of determining the number of shares of Stock available for issuance under Section 3(a)(i), as an Award for one share of Stock for each such share of Stock actually subject to the Award.

        (c)    Changes in Stock.    Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Parent's capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Parent, or additional shares or new or different shares or other securities of the Parent or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the

assets of the Parent the outstanding shares of Stock are converted into or exchanged for securities of the Parent 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 of Stock Options that can be granted to any one individual grantee and the maximum number of shares that may be granted under a Performance-Based Award, (iii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iv) the repurchase price, if any, per share subject to each outstanding Restricted Stock Award, (v) the number of Stock Options automatically granted to Non-Employee Directors, and (vi) the price for each share subject to any then outstanding Stock Options under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options) as to which such Stock Options 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 of Stock 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 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 Parent shall make or provide for a cash payment to the grantees holding Options, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of shares of Stock subject to outstanding Options (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.

        (e)    Substitute Awards.    The Administrator may grant Awards under the Plan in substitution for stock and stock based awards held by employees, directors or other key persons of another corporation in connection with the merger or consolidation of the employing corporation with the Parent or a Subsidiary or the acquisition by the Parent 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)(i).

SECTION 4.ELIGIBILITY    

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

SECTION 5.STOCK OPTIONS    

        Any Stock Option 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 Parent 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)    Stock Options Granted to Employees, Non-Employee Directors and Key Persons.    The Administrator in its discretion may grant Stock Options to eligible employees, Non-Employee Directors, and key persons of the Parent or any Subsidiary. Stock Options 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. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the optionee's election, subject to such terms and conditions as the Administrator may establish.

(i)    Exercise Price.    The exercise price per share for the Stock covered by a Stock Option 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 option price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date.

(ii)    Option Term and Termination.    The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than ten years after the date the Stock Option 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 Parent and its Subsidiaries terminates for any reason (including if a Subsidiary ceases to be a Subsidiary of the Parent), the portion of each Stock Option 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 until the earlier of three months after such date of termination or the expiration of the stated term of such Stock Option.

(iii)    Exercisability; Rights of a Stockholder.    Stock Options 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. The Administrator may waive the foregoing restriction in the case of a grantee's death, disability or retirement or upon a Sale Event. Subject to the foregoing, the Administrator may otherwise at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options.

(iv)    Method of Exercise.    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 of Stock issuable upon such exercise, based, in each case, on the Fair Market Value of the Stock 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 of Stock 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 Parent a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Parent cash or a check payable and acceptable to the Parent 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 Parent or of the transfer agent of the shares of Stock 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 Parent 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 Parent is obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock 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 Parent 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)    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 of Stock with respect to which Incentive Stock Options granted under the Plan and any other plan of the Company or its parent and 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 Stockholder.    Upon the grant of a Restricted Stock Award and payment of any applicable

purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Stock 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 Restricted Stock shall be accompanied by a notation on the records of the Parent or the transfer agent to the effect that they are subject to forfeiture until such Restricted Stock are vested as provided in Section 6(d) below, and (ii) certificated Restricted Stock shall remain in the possession of the Company until such Restricted Stock is 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 of Restricted Stock have vested and if any such Restricted Stock is forfeited, the grantee shall have no rights to any such accrued dividends.

        (c)    Restrictions.    Restricted Stock 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 Parent and its Subsidiaries terminates for any reason (including if a Subsidiary ceases to be a Subsidiary of the Parent), any Restricted Stock that has 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 Parent or its Subsidiaries, be deemed to have been reacquired by the Parent 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 Parent by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of unvested Restricted Stock that are represented by physical certificates, a grantee shall surrender such certificates to the Parent upon request without consideration.

        (d)    Vesting of Restricted Stock.    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 and the Parent'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, and in the event any such Restricted Stock Award granted to employees shall have a time-based restriction, the total restriction period with respect to such Restricted Stock Award shall not be less than three years; provided, however, that any Restricted Stock Award with a time-based restriction may become vested incrementally over such three-year period. The Administrator may waive the foregoing restriction in the case of a grantee's death, disability or retirement or upon a Sale Event. 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 Restricted Stock 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 of Restricted Stock that have not vested shall automatically terminate upon the grantee's termination of employment (or other service relationship) with the Parent and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Parent) and such shares shall be subject to the provisions of Section 6(c) above.

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, and in the event any such Restricted Stock Unit Award granted to employees shall have a time-based restriction, the total restriction period with respect to such Restricted Stock Unit Award shall not be less than three years; provided, however, that any Restricted Stock Unit Award with a time-based restriction may become vested incrementally over such three-year period. The Administrator may waive the foregoing restriction in the case of a grantee's death, disability or retirement or upon a Sale Event. At the end of the restriction period, the Restricted Stock Unit Award, to the extent vested, shall be settled in the form of shares of Stock. 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.

        (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 Stock 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 Stockholder.    A grantee shall have the rights as a stockholder only as to shares of Stock 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 Parent and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Parent).

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 of Stock, 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 Parent and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Parent).

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, and such other limitations and conditions as the Administrator shall determine.

        (b)    Rights as a Stockholder.    A grantee receiving a Performance Share Award shall have the rights of a stockholder 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 of Stock 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 Parent and its Subsidiaries for any reason (including if a Subsidiary ceases to be a Subsidiary of the Parent).

SECTION 10.PERFORMANCE-BASED AWARDS TO COVERED EMPLOYEES    

        (a)    Performance-Based Awards.    Any Covered Employee 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. The Administrator shall define in an objective fashion the manner of calculating the Performance Criteria it selects to use for any Performance Cycle. Depending on the Performance Criteria used to establish such Performance Goals, the Performance Goals may be expressed in terms of overall performance of the Parent 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 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 Parent or its Subsidiaries, or the financial statements of the Parent or its Subsidiaries, or (iii) in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles, or business conditions provided however, that the Administrator may not exercise such discretion in a manner that would increase the Performance-Based Award granted to a Covered Employee. 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 Covered Employee, the Administrator shall select, within the first 90 days of a Performance Cycle (or, if shorter, within the maximum period allowed under Section 162(m) of the Code) 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 Covered Employees.

        (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 Covered Employee's Performance-Based Award, and, in doing so, may reduce or eliminate the amount of the Performance-Based Award for a Covered Employee if, in its sole judgment, such reduction or elimination is appropriate.

        (d)    Maximum Award Payable.    The maximum Performance-Based Award payable to any one Covered Employee under the Plan for any twelve month period constituting all or part of a Performance Cycle is 4,000,000 Shares (subject to adjustment as provided in Section 3(b) hereof) or $25 million in the case of a Performance-Based Award that is a Cash-Based Award.

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 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 Parent 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, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the grantee

for Federal income tax purposes, pay to the Parent or its Subsidiaries, or make arrangements satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Parent or its Subsidiaries with respect to such income. The Parent 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 Parent's obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee.

        (b)    Payment in Stock.    In connection with its obligations to withhold Federal, state, city or other taxes from amounts paid to grantees, the Parent 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 Parent shall have the right to reduce the number of shares of Stock 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 Federal, state, city or other taxes as shall be required to be withheld by the Parent or its Subsidiaries pursuant to any statute or other governmental regulation or ruling and paid to any Federal, state, city or other 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 Parent from a Subsidiary or from the Parent 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 Parent 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 stockholder approval, in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options 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 Stock is listed, to the extent 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, or to ensure that compensation earned under Awards qualifies as performance-based compensation under Section 162(m) of the Code, Plan amendments shall be subject to approval by the stockholders of the Parent entitled to vote at a meeting of stockholders. 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, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Parent 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 Parent's obligations to deliver Stock 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 Stock pursuant to an Award to represent to and agree with the Parent in writing that such person is acquiring the shares without a view to distribution thereof.

        (b)    Delivery of Stock Certificates.    Stock certificates to grantees under the Plan shall be deemed delivered for all purposes when the Parent or a stock transfer agent of the Parent 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 Parent. Uncertificated Stock shall be deemed delivered for all purposes when the Parent or a Stock transfer agent of the Parent 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 Parent 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 Parent shall not be required to issue or deliver any certificates evidencing shares of Stock 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 of Stock are listed, quoted or traded. All Stock 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 federal, state or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate to reference restrictions applicable to the Stock. 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)    Stockholder Rights.    Until Stock is deemed delivered in accordance with Section 17(b), no right to

vote or receive dividends or any other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option 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 Parent or any Subsidiary.

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

        (f)    Forfeiture of Awards.    If the Parent is required to prepare an accounting restatement due to the material noncompliance of the Parent, as a result of misconduct, with any financial reporting requirement under the securities laws, then any grantee who is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002 shall reimburse the Parent for the amount of any Award received by such individual under the Plan during the 12-month period following the first public issuance or filing with the United States Securities and Exchange Commission, as the case may be, of the financial document embodying such financial reporting requirement. In addition, the Awards granted hereunder to the executive officers of the Parent are subject to the clawback policy of Parent in effect from time to time.

        (g)    Section 82 and Section 1043 of the Companies Act.    The Parent 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 shall become effective upon approval by the holders of a majority of the votes cast at a meeting of stockholders at which a quorum is present. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the Effective Date and no grants of Incentive Stock Options may be made hereunder after the tenth anniversary of the date the Plan is 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 Parent to arbitration pursuant to the procedures set forth in the applicable grant agreement of any grantee so affected.
