Exhibit 10.19-11

2018 Plan Award Certificate –Time-Vesting Restricted Stock Unit Award (Reporting Officer)

Effective [Grant Date] (the “Grant Date”), you have been granted a time-vesting restricted stock unit award (the "RSU"). The RSU is for a total of [Award Grant Amount] ordinary shares, par value $0.01 per share (the “Shares”), of Alkermes plc (the “Company”).

The RSU was granted under the Alkermes plc 2018 Stock Option and Incentive Plan (the “Plan”), and is governed by the terms and conditions thereof and of this award certificate (this “Award Certificate”). A copy of the Plan is posted on your local human resources page of the Company’s website. Unless otherwise defined in this Award Certificate, all capitalized terms used in this Award Certificate shall have the respective meanings ascribed to them in the Plan.

Vesting details for the RSU are available via your Bank of America Merrill Lynch Benefits Online account.

You must be employed by the Company on each vesting date in order to receive the Shares that vest on each such date, except as otherwise provided below. For purposes of the RSU, and as set forth in Section 14 of the Plan, you will continue to be deemed employed by the Company for so long as you (x) remain employed by the Company or any Subsidiary, regardless of any transfer between the Company or such Subsidiary or between Subsidiaries, or any transfer from one eligibility category under Section 4 of the Plan to another, or (y) are on an approved leave of absence from the Company or any Subsidiary.

The Company will deliver to you a number of Shares equal to the number of vested Shares underlying your RSU, subject to the satisfaction of tax withholding obligations as set forth in the Plan, within three business days of each applicable vesting date. Delivery of the Shares in settlement of your RSU is intended to comply with the requirements for the short-term deferral exemption available under Treasury Regulations Section 1.409A-1(b)(4) and shall be construed and administered in such manner.

In the event of the termination of your employment or other service relationship with the Company by reason of death or permanent disability, the RSU shall automatically vest and be exercisable in full effective upon such termination.

In the event of a Sale Event, the following provisions shall apply in lieu of and expressly supersede Section 3(d) of the Plan:

1

If within twenty-four (24) months after a Change in Control occurs, your employment is terminated by the Company or any of its Subsidiaries (or its successor in interest) without Cause (as such term is defined in your Employment Agreement) or you terminate your employment for Good Reason (as such term is defined in your Employment Agreement), then, to the extent the RSU is outstanding and not vested immediately prior to the Date of Termination (as defined in your Employment Agreement), it shall become fully vested on the Date of Termination; provided, however, that if such Change in Control is not a Sale Event, the effective date of such vesting shall be the later of (i) the Date of Termination or (ii) the one-year anniversary of the Grant Date.  For purposes of the foregoing, the determination of whether your employment is terminated without Cause or for Good Reason will be made by the Company (or its successor in interest) in accordance with the terms of your Employment Agreement.

The grant of the RSU does not infer any right to, or expectation of, the grant of any additional Options or other Awards on the same basis or at all, in any future year. Participation in the Plan shall in no way give you any rights to compensation for any claim of loss in relation to the Plan, including without limitation:

Any controversy or claim arising out of or relating to this Award Certificate and/or the RSU shall, to the fullest extent permitted by law, be settled by arbitration in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the American Arbitration Association (“AAA”) in Boston, Massachusetts, USA, in accordance with the Employment Arbitration Rules and Mediation Procedures of the AAA, including, but not limited to, the rules and procedures applicable to the selection of arbitrators. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.

2

You may not be issued any Shares in respect of the RSU unless either (i) the Shares are registered under the Securities Act of 1933, as amended (the “Securities Act”); or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. The RSU also must comply with other applicable laws and regulations governing the RSU, and you will not receive such Shares if the Company determines that such receipt would not be in material compliance with such laws and regulations.

The Company has no duty or obligation to minimize the tax consequences to you of the RSU and will not be liable to you for any adverse tax consequences to you arising in connection with the RSU. You are advised to consult with your own personal tax, financial and/or legal advisors regarding the tax consequences of the RSU.

This Award Certificate may not be modified or amended except in a writing signed by you and a duly authorized officer of the Company. Notwithstanding the foregoing, the Administrator reserves the right to modify or amend, by written notice to you, the terms of the RSU and/or this Award Certificate in any way it may deem necessary or advisable (i) as a result of any change in applicable laws or regulations, or any future law, regulation, ruling, or judicial decision, in each case applicable to the RSU, or (ii) for any other legal purpose, provided that (in each case of (i) or (ii) above), no such modification or amendment shall adversely affect your rights under the RSU and/or this Award Certificate without your written consent.
