    WHEREAS, Parker-Hannifin Corporation (the “Company”) sponsors the Parker-Hannifin Corporation Executive Deferral Plan (the “Plan”), which was originally effective October 1, 1994, and amended and restated in its entirety as of September 2, 2015;

    WHEREAS, the Board of Directors of the Company reserves the right pursuant to Article 15 of the Plan to amend or modify the Plan; and

    WHEREAS, the Company desires to amend the Plan to (i) discontinue the inclusion of payments to Specified Employees that would have been made between the Participant’s Retirement and the actual date of commencement of payment if the Participant had not been a Specified Employee and (ii) freeze all future deferrals, credits and contributions to Plan Accounts as of the Plan Year ending December 31, 2022, except as to any deferrals of bonus compensation earned beginning in 2022 and deferred to the Plan in 2023.

    NOW, THEREFORE, pursuant to such actions of the Board of Directors of the Company the Plan is hereby amended as follows effective as of August 1, 2022:

Payment of a Participant’s Account shall be made or shall begin as of the first day of the second month after the Participant’s Retirement or on the first day of the month following the first, second, third, fourth or fifth anniversary of the Participant’s Retirement, as elected by the Participant in accordance with the terms of Section 6.4. Notwithstanding the foregoing, payment to any Specified Employee will commence on the first day of the seventh month following the Participant’s Retirement.

Article 9    If a Participant suffers a Disability prior to Termination of Employment, the Participant shall be eligible for a benefit under the Plan.
