shall apply to this Agreement, including as described in Section 16 of this Agreement), the Option shall vest and first become exercisable in equal increments (excluding any fractional shares) as follows:
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



[TO BE PROVIDED]



|6. | Exercise of Vested Option. Except as otherwise provided in Section 11 of the Plan, the rules of which shall apply to this Agreement, including as described in
Section 16 of this Agreement, the Option shall be exercisable only while Optionee is in the employ of STERIS. To the extent exercisable under the Agreement, the Option may be exercised from time to time in whole or in part.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7. | Method of Exercise. A request to exercise the Option requires delivery of (a) the Option Price payable in cash or by check acceptable to the Company or by wire
transfer of immediately available funds, or by such other methods as may be approved by the Board or the Chief Executive Officer or his delegatee or delegatees, as applicable and (b) a written notice to STERIS identifying this Agreement
and specifying the number of Common Shares as to which the Option is being exercised. Subject to the terms of the Plan and this Agreement, STERIS shall deliver to Optionee certificates representing the Option shares as soon as administratively
feasible following such exercise.

|8. | Certain Determinations. Application, violation, or other interpretation of the terms of this Agreement, the Plan, the Policy, any Prior Agreement, or any
STERIS policy shall be determined by the Board or
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | the Chief Executive Officer or his delegatee or delegatees, if applicable, in its sole discretion, and its determination shall be final and binding on
Optionee and STERIS.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|9. | Termination of the Plan; No Right to Future Grants; No Right of Employment; Extraordinary Item of Compensation. By entering into this Agreement, Optionee acknowledges:
(a) that the Plan is discretionary in nature and may be suspended or terminated by STERIS at any time; (b) that each grant of an Option is a one-time benefit which does not create any contractual or other right to receive future grants of
Options, or benefits in lieu of Options; (c) that all determinations with respect to any such future grants, including, but not limited to, the times when the Option shall be granted, the number of shares subject to each Option, the Option
Price, and the time or times when each Option shall be exercisable, will be at the sole discretion of STERIS; (d) that Optionees participation in the Plan shall not create a right to further employment with Optionees employer and
shall not interfere with the ability of Optionees employer to terminate Optionees employment relationship at any time with or without cause; (e) that Optionees participation in the Plan is voluntary; (f) that the value of
the Options is an extraordinary item of compensation which is outside the scope of Optionees employment contract, if any; (g) that the Option is not part of normal and expected compensation for purposes of any other employee benefit plan
or program of STERIS, including for purposes of calculating any severance, resignation, redundancy, end of service, bonus, long-service, pension or retirement benefits or similar payments; (h) that the right to purchase stock ceases upon
termination of employment for any reason except as may otherwise be explicitly provided in the Plan or this Agreement; (i) that the future value of the shares is unknown and cannot be predicted with certainty; (j) that, where
Optionees employer is a Subsidiary or affiliate of STERIS, the Option has been granted to Optionee in Optionees status as an employee of such Subsidiary or affiliate, and can in no event be understood or interpreted to mean that STERIS
is Optionees employer or that Optionee has an employment relationship with STERIS; and (k) that if the underlying shares do not increase in value, the Option will have no value.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|10. | Employee Data Privacy. By entering into the Agreement, and as a condition of the grant of the Option, Optionee consents to the collection, use and transfer of personal data
as described in this Section 10. Optionee understands that STERIS and its Subsidiaries hold certain personal information about Optionee, including, but not limited to, Optionees name, home address and telephone number, date of birth,

Plan (Data Recipients). Optionee understands that these Data Recipients may be located in Optionees country of residence, the European Economic Area, and in countries outside the European Economic Area, including the United States.
Optionee authorizes the Data Recipients to receive, possess, use, retain and transfer Data in electronic or other form, for the purposes of implementing, administering and managing the Plan, including any transfer of such Data, as may be necessary
or appropriate for the administration of the Plan and/or the subsequent holding of shares of stock on Optionees behalf, to a broker or third party with whom the shares acquired on exercise may be deposited. Optionee 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. Optionee further understands that withdrawing consent may affect Optionees ability to participate in the
Plan, at the sole discretion of the Board or the Chief Executive Officer or his delegatee or delegatees, if applicable.
