THIS RETENTION INCENTIVE AWARD AGREEMENT (the “Agreement”) is made as of March 3, 2021 by and between Allegion plc (“Company”) and Timothy Eckersley (“Employee”). In this Agreement, “Employer” means Schlage Lock Co. LLC, its successors and assigns and “Group Company” means Allegion plc, Schlage Lock Co. LLC, or any subsidiary or other company affiliated with Allegion plc and the successors and assigns of any such company.

WHEREAS, the Company has decided to provide a retention incentive opportunity to Employee; and

WHEREAS, subject to the terms of this Agreement, the Company wishes to incent Employee to continue employment with the Employer, to meet certain performance conditions, to provide continuity and otherwise to continue to perform at an acceptable level.

NOW, THEREFORE, for good and valuable consideration, the Company and Employee hereby agree as follows:

a)Active Employee. For purposes of this Agreement, Employee will be considered an “Active Employee” on a given date if, on that date, Employee remains actively employed by the Employer or another Group Company, and continues to perform the duties assigned for the purposes of this Agreement, has not given oral or written notice of intent to resign or retire as of a date prior to the end of the Retention Period, and has not engaged in any conduct that would constitute “Cause” (as defined herein).

b)Cause. For purposes of this Agreement, the term “Cause” shall mean (i) any action by Employee involving willful malfeasance or willful gross misconduct having a demonstrable adverse effect on the Company or another Group Company; (ii) Employee being convicted of a felony under the laws of the United States or any state or district (or the equivalent in any foreign jurisdiction); or (iii) any material violation of the Company’s code of conduct, as in effect from time to time.

c)Retention Period. For the purposes of this Agreement, the Retention Period shall mean the period from the date of this Agreement until March 3, 2024.

a)Incentive Award.

The Compensation Committee of the Company's board of directors (the “Board”), has approved equity incentive awards (together, the “Incentive Award”) with a total aggregate value of $1,500,000 to be granted to Employee in accordance with Paragraph 2(b) herein. If Employee remains an Active Employee through the Retention Period (except as otherwise set forth herein) and meets any other applicable conditions, the Incentive Award will vest and a number of the Company's ordinary shares (“Shares”) will be issued to Employee.

b)Incentive Award Distribution.

i.The Incentive Award will be delivered in the form of restricted stock units (“RSUs”) with a grant date value of $750,000; and performance stock units (“PSUs”) with a grant date value of $750,000.

i.The RSUs are expected to be granted on March 10, 2021 and would vest ratably over 3 years from the grant date (provided the applicable vesting conditions are met).

ii.The PSUs are expected to be granted on March 10, 2021 and would vest after three years from the grant date to the extent the applicable performance conditions as described in Appendix A are met, as determined by the Compensation Committee of the Board, and other vesting conditions are met.

a.The total number of RSUs and PSUs granted each will be calculated by dividing the $750,000 value of the respective award by the fair market value of one Share on the grant date and rounding up to the nearest whole Share. The number of RSUs and PSUs will be fixed on the grant date accordingly and the number of Shares to be issued to Employee at the time of vesting of the RSUs and PSUs will be equal to the number of RSUs granted and the number of PSUs earned based on achievement of the performance conditions. The future value of the Shares underlying those RSUs and PSUs is unknown and cannot be predicted with certainty. Therefore, the actual value of the Shares Employee may receive at the time of vesting of the RSUs and PSUs, as applicable, could turn out to be less than, or more than, $750,000.

b.The RSUs and PSUs will be granted under, and subject to the terms and conditions of, the Company’s Incentive Stock Plan of 2013 (the “Plan”), as well as the terms and conditions of the applicable RSU and PSU agreements, which will be provided to Employee as soon as practicable after the grant date and which Employee will be required to sign or accept in accordance with the Company’s acceptance procedures. If there is any conflict between the terms of this Agreement and the terms of the Plan and the RSU and PSU agreements, the terms of the Plan and the RSU and PSU agreements will prevail.

c.Tax and Applicable Withholdings. As further detailed in the Plan and the RSU and PSU agreements, the Company and the Employer shall have the right to withhold any federal, state, and local taxes in order for the Company and the Employer to satisfy any withholding tax obligation they may have under any applicable law or regulation.

i.Termination of Employment.

The treatment of the Incentive Award upon Employee's termination of employment is set forth in full in the Plan and the RSU and PSU agreements but is summarized below.

i.Cause or Voluntary Resignation: If (i) Employee engages in any conduct that would constitute Cause, or Employee’s employment with the Company or any other Group Company is terminated for Cause or (ii) Employee voluntarily resigns from employment with the Company or any other Group Company prior to the expiration of the Retention Period, all unvested RSUs shall be forfeited as of the date of termination.

Employee acknowledges that irreparable injury will result to the Company, and to its business, in the event of a material breach by Employee of any of Employee’s covenants and commitments under this Agreement.
