         This certifies that ____________________, or registered assigns, is the
registered holder of the number of Rights set forth above, each of which
entitles the registered holder thereof, subject to the terms, provisions and
conditions of the Shareholder Protection Rights Agreement, dated as of January

Parker-Hannifin Corporation, an Ohio corporation (the "Company"), and KeyBank
National Association, a National Banking Association, as Rights Agent (the
"Rights Agent", which term shall include any successor Rights Agent under the
Rights Agreement), to purchase from the Company at any time after the Separation
Time (as such term is defined in the Rights Agreement) and prior to the close of
business on January 31, 2007, one fully paid share of Common Stock, par value
$.50 per share (the "Common Stock"), of the Company (subject to adjustment as
provided in the Rights Agreement) at the





Exercise Price referred to below, upon presentation and surrender of this Rights
Certificate with the Form of Election to Exercise duly executed at the principal
office of the Rights Agent in the City of New York, New York or the City of
Cleveland, Ohio. The Exercise Price shall initially be $150 per Right and shall
be subject to adjustment in certain events as provided in the Rights Agreement.

         In certain circumstances described in the Rights Agreement, the Rights
evidenced hereby may entitle the registered holder thereof to purchase
securities of an entity other than the Company as provided in the Rights
Agreement.

         This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Rights Agent, the Company and the holders of the Rights Certificates. Copies of
the Rights Agreement are on file at the principal office of the Company and are
available without cost upon written request.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the office of the Rights Agent designated for such purpose,
may be exchanged for another Rights Certificate or Rights Certificates of


                                       -2-



like tenor evidencing an aggregate number of Rights equal to the aggregate
number of Rights evidenced by the Rights Certificate or Rights Certificates
surrendered. If this Rights Certificate shall be exercised in part, the
registered holder shall be entitled to receive, upon surrender hereof, another
Rights Certificate or Rights Certificates for the number of whole Rights not
exercised.

         Subject to the provisions of the Rights Agreement, each Right evidenced
by this Certificate may be (a) redeemed by the Company under certain
circumstances, at its option, at a redemption price of $0.01 per Right or (b)
exchanged by the Company under certain circumstances, at its option, for one
share of Common Stock per Right (or, in certain cases, other securities or
assets of the Company), subject in each case to adjustment in certain events as
provided in the Rights Agreement.

         No holder of this Rights Certificate, as such, shall be entitled to
vote or receive dividends or be deemed for any purpose the holder of any
securities which may at any time be issuable on the exercise hereof, nor shall
anything contained in the Rights Agreement or herein be construed to confer upon
the holder hereof, as such, any of the rights of a stockholder of the Company or
any right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive


                                       -3-



notice of meetings or other actions affecting stockholders (except as provided
in the Rights Agreement), or to receive dividends or subscription rights, or
otherwise, until the Rights evidenced by this Rights Certificate shall have been
exercised or exchanged as provided in the Rights Agreement.

         This Rights Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.

         WITNESS the facsimile signature of the proper officers of the Company
and its corporate seal.
