5

Mural Group (due to the operation of transfer of undertakings or similar Law or regulation), the Parties shall cooperate and take such actions as may be reasonably necessary in order to cause the employment of such individuals to be promptly transferred to a member of the Alkermes Group.

(c)The Parties shall cooperate and take such actions as may be reasonably necessary in order to minimize potential statutory, contractual, plan-based or other severance or similar obligations to the Parties or their Affiliates in connection with any transfers of employment described in this Section 2.1.

(d)Mural will determine which, if any, temporary workers, individual consultants or independent contractors who are performing service primarily related to the Oncology Business, it wishes to transfer to a Mural Group member, and the Parties shall use reasonable efforts to transfer the individual or to assign the applicable Contract to a member of the Mural Group and Mural shall, or shall cause a member of the Mural Group to, assume and perform such Contract.

Section 2.2 Assumption and Retention of Liabilities. Alkermes and Xxxxx intend that employment-related Liabilities associated with Alkermes Participants are to be retained or assumed by Alkermes or an Alkermes Group member (other than, for the avoidance of doubt, a Mural Group member), and employment-related Liabilities associated with Mural Participants are to be assumed by Mural or a Mural Group member, in each case, except as specifically set forth herein. Accordingly, as of the Distribution Effective Time:

(a)Alkermes or the applicable member of the Alkermes Group hereby retains or assumes and agrees to pay, perform, fulfill and discharge, except as expressly provided in this Agreement, (i) all Liabilities arising under or related to Alkermes Plans, (ii) all employment or service-related Liabilities with respect to (A) all Alkermes Participants and (B) any individual who is, or was, an independent contractor, temporary employee, temporary service worker, consultant, freelancer, agency employee, leased employee, on-call worker, incidental worker or non-payroll worker or in any other employment or similar relationship primarily connected to Alkermes or an Alkermes Group member and (iii) any Liabilities expressly transferred or allocated to Alkermes or an Alkermes Group member under this Agreement; and

Section 2.5 No Duplication of Benefits; Service and Other Credit. Alkermes and Mural shall adopt, or cause to be adopted, all reasonable and necessary amendments and procedures to prevent Mural Participants from receiving duplicative benefits from the Alkermes Plans and the Mural Plans. With respect to Mural Employees, each Mural Plan shall provide that for purposes of determining eligibility to participate, vesting and entitlement to benefits, service prior to the Distribution Effective Time with Alkermes or an Alkermes Group member shall be treated as service with Mural or the applicable Mural Group member. Such service also shall apply for purposes of satisfying any waiting periods, evidence of insurability requirements, or the application of any preexisting condition limitations under any Mural Plan. Each Mural Plan shall, to the extent practicable, waive pre-existing condition limitations with respect to Mural Employees. To the extent permitted under the applicable plan, Mural shall procure that the applicable Mural Group member shall honor any deductibles incurred by Mural Employees and their eligible dependents under any Alkermes medical plan in which they participated immediately prior to the Distribution Effective Time during the then-elapsed portion of the calendar year prior to the Distribution Effective Time for purposes of satisfying any deductibles or out-of-pocket maximums under the Mural Plans in which they are eligible to participate after the Distribution Effective Time in the same plan year in which such deductibles were incurred. For the avoidance of doubt, the Mural Group shall not be required to honor any co-payments incurred by Mural Employees or their eligible dependents under any Alkermes Health and Welfare Plan for purposes of satisfying any out-of-pocket maximums under the Mural Plans in which they are eligible to participate after the Distribution Effective Time.

Section 2.6 Reimbursements. From time to time after the Distribution Effective Time, the Parties shall reimburse one another, within sixty (60) days following reasonable request of the Party requesting reimbursement and the presentation by such Party of such substantiating documentation as the other Party shall reasonably request, for the cost of any Liabilities satisfied or assumed by the Party requesting reimbursement or its Affiliates that are made, pursuant to this Agreement, the responsibility of the other Party or any of its Affiliates.

Section 2.7 Approval of Plans. Prior to the Distribution Effective Time, Alkermes shall have caused Mural to adopt the Mural Stock Plan and an employee stock purchase plan intended to meet the requirements of Section 423 of the Code and the regulations promulgated thereunder (the “Mural ESPP”) and have taken all actions as may be necessary to approve the Mural Stock Plan and the Mural ESPP in order to satisfy the applicable requirements of the Code and the applicable rules and regulations of Nasdaq.

Alkermes shall use commercially reasonable efforts (i) to assist Mural in completing such registration and (ii) to cause a registration statement on Form S-8 (or other appropriate form) of Alkermes to remain in effect for so long as there may be an obligation to deliver Alkermes shares under any Alkermes Stock Plan.

Section 2.9 No Change in Control. Alkermes and Mural each hereby agree that none of the transactions contemplated by the Separation Agreement or any of the Ancillary Agreements, including this Agreement, constitutes a “change in control,” “change of control,” “sale event,” or transaction having a similar name, as applicable, within the meaning of any Alkermes Plan or Mural Plan and, except as provided in this Agreement or as otherwise required by applicable law, no provision of this Agreement shall be construed to accelerate any vesting or create any rights or entitlement to any compensation or benefits on the part of any employee.

Section 2.10 Labor Relations. To the extent required by applicable Law, the Parties shall cooperate to provide notice, engage in consultation and take any similar action which may be required on its part in connection with the Separation.

All other Mural Employees shall become eligible to participate in the Mural 401(k) Plan as provided under the terms of such plan.

(b)Severance from Employment.

(c)Post-Distribution Effective Time Contributions. If any Mural Employees are entitled to employer matching contributions under the terms of the Alkermes 401(k) Plan (or any other employer contributions under such plan) with respect to contributions made by Mural Employees into the Alkermes 401(k) Plan in the 2023 plan year prior to becoming a Mural Employee, and such employer matching contributions have not yet been deposited into the Mural Employees’ accounts under the Alkermes 401(k) Plan as of the Distribution Effective Time, then Alkermes and Mural shall cooperate to make such amendments, if any, to the Alkermes 401(k) Plan and/or the Mural 401(k) Plan and/or to take such other actions as may be necessary or appropriate to ensure that the Mural Employees are given the full economic benefit of such employer matching contributions as soon as practicable following the determination of such employer matching contribution (and other employer contribution, if any) amounts. For the avoidance of doubt, it is the intention of the parties hereto that the cost of the employer matching contribution (and other employer contributions, if any) described herein be borne by Alkermes.

Effective on or about the Distribution Date, Mural Employees who were participating in the Alkermes Health and Welfare Plans as of the date immediately prior to the Distribution Date shall cease to participate in the Alkermes Health and Welfare Plans and shall, as applicable, commence participation in the corresponding Mural Health and Welfare Plan in which they have enrolled.

All outstanding Liabilities relating to, arising out of or resulting from health and welfare coverage or claims incurred by or on behalf of Mural Employees or their covered dependents under the Alkermes Health and Welfare Plans on or before the Distribution Effective Time shall be retained by the Alkermes Group. Any Liabilities relating to, arising out of or resulting from health and welfare coverage or claims incurred by or on behalf of Mural Employees or their covered dependents under the Alkermes Health and Welfare Plans following the Distribution Effective Time shall be assumed by a member of the Mural Group; provided, however, that to the extent such a Liability is covered under an insurance policy maintained with respect to an Alkermes Health and Welfare Plan regardless of when the Liability arises, and such Liability is not covered under an insurance policy maintained with respect to a Mural Health and Welfare Plan, such Liability shall be retained by the Alkermes Group to the extent of such coverage; and provided further, however,

9

that to the extent that the Alkermes Group receives prior to the Distribution Effective Time an invoice from a service provider billing the Alkermes Group for a service or product relating to health or welfare coverage for Mural Employees or their covered dependents following the Distribution Effective Time, the Alkermes Group shall be responsible for paying such invoice and a member of the Mural Group shall reimburse the Alkermes Group for any amount paid by the Alkermes Group.

Section 4.3 Flexible Spending Plan Treatment.

Any workers’ compensation Liabilities relating to, arising out of, or resulting from any claim by Mural Employees that result from an accident or from an occupational disease which is incurred or becomes manifest, as the case may be, following the Distribution Effective Time shall be assumed by Mural; provided, however, that to the extent such a Liability is covered under a workers compensation insurance policy of Alkermes or an Alkermes Group member regardless of when the Liability arises, and such Liability is not covered under a workers compensation insurance policy of Mural or a Mural Group member, such Liability shall be retained by Alkermes or an Alkermes Group member to the extent of such coverage; and provided further, however, that to the extent that Alkermes or an Alkermes Group member, as applicable, receives prior to the Distribution Effective Time an invoice for a covered expense with respect to such Liability, Alkermes shall be responsible for paying such invoice and Mural shall reimburse Alkermes for any amount paid by Alkermes. Notwithstanding the foregoing, Xxxxx shall assume worker’s compensation Liabilities to the extent they are imposed on Mural under applicable Law or where the injury or illness related to the Liability is aggravated or subject to further injury after the Distribution Effective Time. A Liability which must be paid due to the existence of a deductible shall not be deemed to be covered by a workers compensation insurance policy for purposes of this Section 4.4. Subject to the foregoing, Mural and each Mural Group member shall also be solely responsible for all workers’ compensation Liabilities relating to, arising out of, or resulting from any claim incurred for a compensable injury sustained by a Mural Employee that results from an accident or from an occupational disease which is incurred or becomes manifest, as the case may be, after the Distribution Effective Time. Alkermes, each Alkermes

Each adjusted Alkermes Option shall be subject to the same terms and conditions regarding type (whether an Incentive Stock Option or a nonqualified Option), grant date, term, vesting, and other provisions regarding exercise as set forth in the original Alkermes Option. Such adjustments shall be done in a manner consistent with the requirements of Section 409A of the Code and, for Incentive Stock Options, Section 424 of the Code.

(c)Alkermes PRSUs.

(i)Alkermes PRSUs held by Alkermes Participants. Upon the Distribution Effective Time, each Alkermes PRSU held by an Alkermes Participant will

13

be equitably adjusted solely into an adjusted Alkermes PRSU. The number of Alkermes Ordinary Shares subject to the adjusted Alkermes PRSU will be equal to the number of Alkermes Ordinary Shares subject to the Alkermes PRSU immediately prior to the Distribution Effective Time multiplied by the Alkermes Conversion Fraction, with the result being rounded down to the nearest whole share. Each adjusted Alkermes PRSU shall be subject to the same terms and conditions regarding grant date, term, vesting and other provisions regarding settlement as set forth in the original Alkermes PRSU award; provided that, the Alkermes Board may authorize such adjustments to the performance goals underlying the applicable Alkermes PRSU award as it determines to be appropriate to reflect the impact of the Separation.

Notwithstanding the foregoing provisions of this Section 5.2, the Parties may mutually agree, in their sole discretion, not to adjust certain outstanding Alkermes Options, RSUs and PRSUs pursuant to the foregoing provisions of this Section 5.2 where those actions would create or trigger adverse legal, accounting or tax consequences for Alkermes, Mural and/or the affected non-U.S. award holder. In such circumstances, Alkermes and/or Mural may take any action necessary or advisable to prevent any such adverse legal, accounting or tax consequences, including agreeing that the outstanding Alkermes Options, RSUs and/or PRSUs of the affected non-U.S. award holders shall terminate in accordance with the terms of the applicable Alkermes Stock Plan and the underlying award agreements, in which case Alkermes or Mural, as applicable, shall equitably compensate the affected non-U.S. award holders in an alternate manner determined by Alkermes or Mural, as applicable, in its sole discretion, or apply an alternate adjustment method. Where and to the extent required by applicable Law or tax considerations outside the United States, the adjustments described in this Section 5.2 shall be deemed to have been effectuated immediately prior to the Distribution Date.

(g)Administration. Each of Alkermes and Mural shall establish an appropriate administration system (through Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated, ETrade Securities LLC and Computershare Trust Company, N.A.) in order to handle exercises and delivery of shares in an orderly manner and provide reasonable levels of service for equity award holders. Upon the Distribution Effective Time, Xxxxx shall succeed to all administrative and interpretive and other rights of Alkermes with respect to awards converted into awards with respect to Mural Ordinary Shares hereunder.

Notwithstanding anything in this Agreement to the contrary, Alkermes and Xxxxx agree to negotiate in good faith regarding the need for any treatment of any payments or benefits hereunder different from that otherwise provided herein to ensure that the treatment of Alkermes or Mural Options, PRSUs, RSUs or other compensation hereunder does not cause the imposition of a tax under Section 409A of the Code.

Section 5.6 Mural Director Obligations. With respect to any non-employee director of Mural following the Distribution Effective Time, Mural shall be responsible for the payment of any fees or other obligations for service on the board of directors of Mural at or at any time after the Distribution Effective Time and any fees or other obligations for the service of a Mural director to the Mural Group prior to the Distribution Effective Time and Alkermes shall not have any responsibility for any such fees or other obligations.

Section 6.5 Fiduciary Matters. Alkermes and Xxxxx each acknowledge that actions required to be taken pursuant to this Agreement may be subject to fiduciary duties or standards of conduct under ERISA or other applicable Law, and no Party shall be deemed to be in violation of this Agreement if it fails to comply with any provisions hereof based upon its good faith determination (as supported by advice from counsel experienced in such matters) that to do so would violate such a fiduciary duty or standard.

If any provision of this Agreement cannot be implemented due to the failure of such third party to Consent, Alkermes and Xxxxx shall negotiate in good faith to implement the provision in a mutually satisfactory manner. The phrase “commercially reasonable efforts” as used herein shall not be construed to require the incurrence of any non-routine or unreasonable expense or liability or the waiver of any right.

17

Section 6.7 Assignment of “Claw-Back” or Recoupment Rights. To the extent a member of the Alkermes Group holds any repayment, “claw-back” or recoupment rights with respect to remuneration paid or provided to Mural Employees (e.g., the right to require repayment of compensation upon a termination of employment or misconduct by the employee) in connection with any relocation benefit, sign-on bonus, tuition benefit or otherwise, other than any repayment, “claw-back” or recoupment rights pursuant to any policy adopted pursuant to Section 10D of the Exchange Act, such rights are hereby assigned to Mural upon the Distribution Effective Time, it being agreed that the transactions contemplated by the Separation Agreement shall not, in and of themselves, trigger any such repayment or recoupment right.
