WHEREAS, (the “Grantee”) is a Director of STERIS plc, a public limited liability company organized under the laws of England and Wales (“STERIS”); and

NOW, THEREFORE, pursuant to the STERIS plc 2006 Long-Term Equity Incentive Plan, Assumed as Amended and Restated Effective November 2, 2015, and as further amended from time to time (the “Plan”), STERIS hereby grants to the Grantee as of ___________ (the “Date of Grant”) ______ Career Restricted Stock Units (the “Units”), subject to the terms and conditions of the Plan and the following additional terms, conditions, limitations and restrictions.


1.	Issuance of Units. The Units represent the right of the Grantee to receive from the Company the number of Ordinary Shares, par value £0.10 per share, of the Company’s capital stock (“Ordinary Shares”) equal to the number of Units granted hereby, as provided herein.

2.Documents Delivered with Agreement. STERIS has delivered or made available to the Grantee, along with this Agreement, the following documents: (a) a copy of STERIS’s Insider Trading Policy (the “Policy”); (b) a copy of the Plan and its related Prospectus; (c) two copies of an acknowledgement form (the “Acknowledgement Form”); and (d) STERIS’s most recent Annual Report to Shareholders on Form 10-K filed with the U.S. Securities and Exchange Commission. Acceptance and compliance with these documents is a condition of the effectiveness of this grant of Units. By accepting this Agreement or executing the Acknowledgement, the Grantee acknowledges receipt, review and acceptance of these documents and compliance with their terms.

3.Vested Units. Subject to the terms of this Agreement and the Plan, the Units and the Grantee’s right to receive the Ordinary Shares subject to the Units are non-forfeitable from and after the Date of Grant.

4.Payment of Units. The Company shall transfer to the Grantee (or to Grantee’s executor or administrator in the event of the Grantee’s death) the Ordinary Shares subject to the Units on the date that is six months after the date that the Grantee ceases to be a Director.

5. Payment of Par Value. By entering into this Agreement, the Grantee undertakes and agrees to pay the par value of £0.10 for each Ordinary Share subject to a Unit granted pursuant to this Agreement (the “Par Value Consideration”) on or before the date of transfer of the Ordinary Share to the Grantee, and in any event within six weeks after the date the Ordinary Shares would otherwise be transferable to the Grantee, as such date may be extended by STERIS in its sole discretion (the “Payment Date”). Such payment of the Par Value Consideration shall be made to the Company by the Grantee in cash or by such other means of payment by the Grantee as may be required or permitted by STERIS. If such payment is not received by the Payment Date, the Ordinary Shares and the right to receive the same shall be forfeited for non-payment pursuant to the Articles of Association of STERIS.

6. Dividend, Voting and Other Rights. Except as otherwise provided herein, from and after the Date of Grant, the Grantee shall have none of the rights of a shareholder with respect to the Units covered by this Agreement, including the right to vote the Ordinary Shares covered by the Units and receive any dividends that may be paid on the Ordinary Shares covered by the Units, until the transfer of the Ordinary Shares covered by the Units to the Grantee pursuant to Section 4 hereof. Notwithstanding the foregoing, from and after the Date of Grant and until the time when the Units are paid in accordance with Section 4

hereof, on the date that STERIS pays a cash dividend (if any) to holders of Ordinary Shares generally, Grantee shall be entitled to receive from the Company a dividend equivalent payment with respect to each outstanding Unit, in the amount per Unit equal to the amount of the dividend payment on each outstanding Ordinary Share. On the date the dividend is paid, the Company shall make such dividend equivalent payment directly to the Grantee in cash subject to any applicable tax withholding obligation.

7. Compliance with Law. Notwithstanding any other provision of this Agreement, STERIS shall not be obligated to issue any Ordinary Shares pursuant to this Agreement if the issuance thereof would result in a violation of any applicable law.

8. Certain Determinations. Application, violation, or other interpretation of the terms of this Agreement, the Plan, the Nondisclosure Agreement, the Policy, or any other STERIS policy shall be determined by the Board in its sole discretion, and such determination shall be final and binding on the Grantee and STERIS.

9. Data Privacy. By entering into the Agreement, and as a condition of this award of Units, the Grantee consents to the collection, use and transfer of personal data as described in this Section 9.

The Grantee understands that he or she may, at any time, review the Data, require any necessary amendments to it or withdraw the consent herein by notifying STERIS in writing. The Grantee further understands that withdrawing consent may affect the Grantee’s ability to participate in the Plan, at the sole discretion of the Board or the Chief Executive Officer or its delegatee or delegatees.

10. Relation to Plan. This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency between the provisions of this Agreement and the Plan, the Plan shall govern. All terms used herein with initial capital letters and not otherwise defined herein that are defined in the Plan shall have the meanings assigned to them in the Plan.

11. Amendments. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto; provided, however, that no amendment shall adversely affect the rights of the Grantee under this Agreement without the Grantee’s consent.

12. Severability. If any provision of this Agreement or the application of any provision hereof to any person or circumstances is held invalid or unenforceable, the remainder of this Agreement and the application of such provision to any other person or circumstances shall not be affected, and the

provisions so held to be invalid or unenforceable shall be reformed to the extent (and only to the extent) necessary to make it enforceable and valid.

13. Taxes. Should any tax withholding obligation be imposed upon the Company at the time the Ordinary Shares would otherwise be transferrable by the Company to the Grantee the Company shall withhold from such Ordinary Shares a sufficient number to satisfy such obligations as a condition to the transfer, or require as a condition that the Grantee satisfy the payment of such obligations by such other means as the Company may determine. Any Ordinary Shares withheld as aforesaid shall be forfeited.

14. Governing Law. This Agreement shall be governed by and construed in accordance with the internal substantive laws of the State of Ohio, without giving effect to any principle of law that would result in the application of the law of any other jurisdiction.

15. Miscellaneous. Nothing contained in this Agreement shall be understood as conferring on the Grantee any right to continue as a Director of STERIS. STERIS reserves the right to correct any clerical, typographical, or other error in this Agreement or otherwise with respect to this grant.
