    WHEREAS, Parker-Hannifin Corporation (the “Company”) sponsors the Deferred Compensation Plan for Directors of Parker-Hannifin Corporation (the “Plan”), which was amended and restated January 22, 2015;

    WHEREAS, the Board of Directors of the Company reserves the right pursuant to Article V Section 2 of the Plan to amend or modify the Plan; and

    WHEREAS, the Company desires to amend the Plan to (i) update Participant elected distribution options available under the Plan and (ii) update the payment terms of Small Account Balances.

    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:

        1.    Payment of Deferral Account. Except as otherwise provided pursuant to this Article IV, a Participant's Account shall be paid monthly over a period of 15 years; provided, however, that the Participant may elect in accordance with Section 2 of this Article to have payment made by one of the following methods:

        (d)    Small Account Balances. Notwithstanding the foregoing, effective August 1, 2022 with respect to Participant’s deferrals under the Plan that would otherwise be paid in installments after August 1, 2022, if the balance of the Participant's Account under the Plan as of the date

payment would otherwise commence is less than or equal to the applicable dollar amount in effect on such date under Section 402(g)(1)(B) of the Code, the Corporation shall pay the Participant's Account in a single lump sum payment
