Other Events.

On September 14, 2026, Parker-Hannifin Corporation (“Parker” or the “Company”) completed (i) its previously announced registered offering of $2.4 billion in aggregate principal amount of senior notes (the “U.S. Notes Offering”) and (ii) its previously announced registered offering of €2.025 billion in aggregate principal amount of senior notes (the “Euro Notes Offering” and, together with the U.S. Notes Offering, the “Offerings”). The U.S. Notes Offering included four tranches, consisting of $525 million aggregate principal amount of senior notes due 2028 (the “2028 U.S. Notes”), $500 million aggregate principal amount of senior notes due 2029 (the “2029 U.S. Notes”), $750 million aggregate principal amount of senior notes due 2031 (the “2031 U.S. Notes”) and $625 million aggregate principal amount of senior notes due 2033 (the “2033 U.S. Notes” and, together with the 2028 U.S. Notes, the 2029 U.S. Notes and the 2031 U.S. Notes, the “U.S. Notes”). The Euro Notes Offering included three tranches, consisting of €700 million aggregate principal amount of senior notes due 2030 (the “2030 Euro Notes”), €800 million aggregate principal amount of senior notes due 2032 (the “2032 Euro Notes”) and €525 million aggregate principal amount of senior notes due 2036 (the “2036 Euro Notes” and, together with the 2030 Euro Notes and the 2032 Euro Notes, the “Euro Notes”). The U.S. Notes and the Euro Notes are collectively referred to as the “Notes.” The offering of the Notes was registered under the Securities Act of 1933, as amended, pursuant to the Registration Statement on Form S-3 (Registration No. 333-298527) (the “Registration Statement”).

The Company intends to use the net proceeds from the Offerings, together with cash on hand, to repay the borrowings under the 364-Day Term Loan Agreement, dated December 10, 2025, among the Company, Barclays Bank PLC and various financial institutions named therein as lenders, incurred in connection with the acquisition of Filtration Group Corporation.

The Notes are subject to customary events of default, including failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness and certain events of bankruptcy, insolvency or reorganization. If the Company experiences certain kinds of changes of control, it will be required to offer to purchase the Notes at 101% of their principal amount, plus accrued and unpaid interest.

The Notes will be senior unsecured obligations of the Company and rank equally in right of payment with all of its other senior unsecured debt and senior in right of payment to all of its subordinated debt, and are effectively subordinated to any of the Company’s secured debt to the extent of the value of collateral securing such debt.

Certain of the underwriters of the Notes and their respective affiliates are full service financial institutions that have engaged in, and may in the future engage in, investment banking, commercial banking and other commercial dealings in the ordinary course of business with the Company or its affiliates, including acting as lenders under the Company’s revolving credit facility. These underwriters or their respective affiliates have received, or may in the future receive, customary fees and commissions or other payments for these transactions.

PARKER-HANNIFIN CORPORATION OFFICER’S CERTIFICATE

ESTABLISHING TERMS OF NOTES UNDER AN OPEN-ENDED INDENTURE

Todd M. Leombruno, Executive Vice President and Chief Financial Officer of Parker-Hannifin Corporation, an Ohio corporation (the

“Company”), does hereby certify in accordance with Sections 201 and 301 of the Indenture, dated as of September 5, 2023 (the “Indenture”), with The Bank of New York Mellon Trust Company, N.A., as trustee

(the “Trustee”), as follows (capitalized terms used herein and not otherwise defined herein are used with the same meanings ascribed to such terms in the Indenture):

Authorization. The establishment of a new series of Securities of the Company has been approved and

authorized in accordance with the provisions of the Indenture pursuant to the resolutions adopted by the Board of Directors (the “Board”) of the Company on September 1, 2026 and the Pricing Committee of the Board on

September 8, 2026.

Compliance with Covenants and Conditions Precedent. All covenants and conditions precedent provided for

in the Indenture relating to the establishment of such series of Securities have been complied with.

Terms. The terms of the series of Securities established pursuant to this Officer’s Certificate

shall be as follows:

(a)

Title: 4.750% Senior Notes due 2028 (the “Notes”);

(b)

Initial Aggregate Principal Amount: $525,000,000;

(c)

Denomination: $2,000 and integral multiples of $1,000 in excess thereof;

(d)

Maturity Date: September 14, 2028;

(e)

Interest Rate: 4.750% per annum, computed on the basis of a

360-day year consisting of twelve 30-day months;

(f)

Interest Payment Date: Semi-annually on March 14 and September 14 of each year, commencing

March 14, 2027;

(g)

Record Date: Business Day immediately preceding the Interest Payment Date;

(h)

Form of Security: The Notes will be issued in the form of Global Securities (each such Global Security,

a “Global Note”); and

(i)

Depositary: The Depository Trust Company.

The Notes shall have the following additional terms:

Principal, Interest and Maturity

Payment

will be made upon presentation of the Notes at the office or agency of the Company maintained for that purpose; provided, however, that payment of interest may be made at the Company’s option by check mailed to the registered holder on the

applicable record date at such address as shall appear in the security register or by wire transfer of immediately available funds to an account specified in writing by such holder to the Company and the Trustee prior to the relevant record date. So

long as the Notes are in book-entry form, the Company will make payments of principal and interest through the Trustee to the Depositary or its nominee, as the case may be, as the registered holder of the Global Notes.

Interest payable on any Interest Payment Date for the Notes, on the redemption date for the

Notes or the maturity date for the Notes will be the amount of interest accrued from, and including, the preceding Interest Payment Date for the Notes in respect of which interest has been paid or duly provided for (or from and including the

original issue date, if no interest has been paid or duly provided for with respect to the Notes) to, but excluding, such Interest Payment Date, redemption date or maturity date, as the case may be. If any Interest Payment Date, redemption date or

maturity date falls on a day that is not a Business Day, the payment otherwise required to be made on such date will be made on the next succeeding Business Day, and the Company will not be liable for any additional interest as a result of the delay

in payment.

Optional Redemption

Prior to September 14, 2028, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a

redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon

discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30 day months) at the Treasury Rate plus 7.5 basis points less (b) interest accrued to, but not

including, the redemption date, and

•

100% of the principal amount of the Notes to be redeemed,

plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date.

For the purposes of the optional redemption provisions of the Notes, the following additional terms will be applicable:

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the

following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as

yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such

time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication)

(“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable:

(1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the maturity date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly

equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the

Remaining Life – and shall interpolate to the maturity date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant

maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on

H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the

Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury

security maturing on, or with a maturity that is closest to, the maturity date. If there is no United States Treasury security maturing on the maturity date, but there are two or more United States Treasury securities with a maturity date equally

distant from the maturity date, one with a maturity date preceding the maturity date and one with a maturity date following the maturity date, the Company shall select the United States Treasury security with a maturity date preceding the maturity

date. If there are two or more United States Treasury securities maturing on the maturity date, or two or more United States Treasury securities meeting the criteria

of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon

the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the

applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three

decimal places.

The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for

all purposes, absent manifest error. The Trustee shall not be responsible for calculating the redemption price.

Notice of any redemption

will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. Any redemption

or notice described above may, at the Company’s discretion, be subject to the satisfaction or waiver of one or more conditions precedent. In addition, if such redemption is subject to satisfaction or waiver of one or more conditions precedent,

the notice of such redemption shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived, or such notice may be rescinded and the redemption

terminated in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption date so delayed. The Company shall notify holders of any such rescission as soon as practicable after the

Company determines that such conditions precedent will not be able to be satisfied or the Company is not able or willing to waive such conditions precedent.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata in accordance with the procedures of the

Depositary (or another depositary) or by lot. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the

principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the

Notes are held by The Depository Trust Company, Euroclear Bank SA/ NV, as operator of the Euroclear System, Clearstream Banking, société anonyme or another depositary, the redemption of the Notes shall be done in accordance with

the policies and procedures of the Depositary.

Unless the Company defaults in payment of the redemption price, on and after the

redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

For the avoidance of doubt, neither

the Trustee nor any paying agent shall be responsible for performing any calculations or selections in connection with any optional redemption.

Repurchase Upon a Change of Control

If a

Change of Control Triggering Event (as defined below) occurs with respect to the Notes, unless the Company has exercised its option to redeem the Notes as described above, the Company will be required to make an offer (a “Change of Control

Offer”) to each holder of the Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s Notes on the terms set forth in such Notes. In a Change of Control Offer, the

Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control

Payment”).

Within 30 days following any such Change of Control Triggering Event or, at the Company’s option, prior to any

Change of Control (as defined below), but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed or electronically delivered, or with respect to Notes held in global form, to

the extent permitted or required by applicable procedures or regulations of the Depositary, sent electronically to holders of the Notes, with a copy to the Trustee under the Indenture that such Notes are being issued under, describing the

transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date will be no earlier than 10 days and (unless delivered in advance of the

occurrence of such Change of Control Triggering Event) no later than 60 days from the date such notice is mailed or sent (a “Change of Control Payment Date”). The notice will, if mailed or sent prior to the date of consummation of

the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring.

On each Change of Control Payment Date, the Company will, to the extent lawful:

•

accept for payment all Notes or portions of Notes properly tendered pursuant to the applicable Change of Control

Offer;

•

deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or

portions of Notes properly tendered; and

•

deliver or cause to be delivered to the Trustee the Notes properly accepted together with an officer’s

certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased.

The Company will

not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for a Change of Control

Offer made by the Company, and the third party repurchases all Notes properly tendered and not withdrawn under its offer.

The Company

will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the

extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the

Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any

such conflict.

If holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw

such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company, as described above, purchases all of the Notes validly tendered and not withdrawn by such holders, the Company will

have the right, upon not less than 10 nor more than 60 days’ prior written notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding

following such purchase at a redemption price in cash equal to the applicable Change of Control Payment.

Neither the Trustee nor any

paying agent shall be responsible for determining whether any Change of Control Triggering Event has occurred and whether any Change of Control Offer with respect to the Notes is required. Neither the Trustee nor any paying agent shall be

responsible for monitoring the Company’s rating status, making any request upon any Rating Agency, or determining whether any rating event with respect to the Notes has occurred.

For purposes of the Change of Control Offer provisions of the Notes, the following terms will be applicable:

“Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, lease, transfer,

any person, other than the Company or one of its subsidiaries; (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any person becomes the beneficial owner (as defined

by voting power rather than number of shares; (3) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any

indirect wholly owned subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s

without objection to such nomination).

Section 3(a)(62) of the Exchange Act selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Fitch, Moody’s or S&P, or all of them, as the case may be, with respect to the Notes.

4.750% Senior Notes due 2028

Parker-Hannifin Corporation, a corporation duly organized and existing under the laws of Ohio (herein called the “Company,”

which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay interest on the principal amount of this Note semi-annually on March 14 and September 14 of each year,

commencing March 14, 2027 at the rate per annum shown above. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the related payment of interest or principal, as applicable, will be made on the next

Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be, to the date the payment is made.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note (or one or more

Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the Business Day immediately preceding the Interest Payment Date. Any such interest not so punctually paid or duly provided

for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for

the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the

requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Payment of the principal of and any such interest on this Note will be made in immediately available funds to the Depositary or its nominee,

as the case may be, as Holder hereof. Payment will be made upon presentation of the Notes at the office or agency of the Company maintained for that purpose.

This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be

issued in one or more series under an Indenture, dated as of September 5, 2023 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as

supplemented by the officer’s certificate, dated September 14, 2026, of Todd M. Leombruno, Executive Vice President and Chief Financial Officer of the Company (the “Officer’s Certificate”) (the Base

Indenture as supplemented by the Officer’s Certificate is collectively referred to herein as the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York

Mellon Trust Company, N.A., as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights,

limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the

face hereof.

Principal, Interest and Maturity

Payment will be made upon presentation of the Notes at the office or agency of the Company maintained for that purpose; provided, however, that

payment of interest may be made at the Company’s option by check mailed to the registered holder on the applicable record date at such address as shall appear in the security register or by wire transfer of immediately available funds to an

account specified in writing by such holder to the Company and the Trustee prior to the relevant record date. So long as the Notes are in book-entry form, the Company will make payments of principal and interest through the Trustee to the Depositary

or its nominee, as the case may be, as the registered holder of the Global Notes.

Interest payable on any Interest Payment Date for the

Notes, on the redemption date for the Notes or the maturity date for the Notes will be the amount of interest accrued from, and including, the preceding Interest Payment Date for the Notes in respect of which interest has been paid or duly provided

for (or from and including the original issue date, if no interest has been paid or duly provided for with respect to the Notes) to, but excluding, such Interest Payment Date, redemption date or maturity date, as the case may be. If any Interest

Payment Date, redemption date or maturity date falls on a day that is not a Business Day, the payment otherwise required to be made on such date will be made on the next succeeding Business Day, and the Company will not be liable for any additional

interest as a result of the delay in payment.

Optional Redemption

Prior to September 14, 2028, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a

redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon

discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30 day months) at the Treasury Rate plus 7.5 basis points less (b) interest accrued to, but not

including, the redemption date, and

•

100% of the principal amount of the Notes to be redeemed,

plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date.

For the purposes of the optional redemption provisions of the Notes, the following additional terms will be applicable:

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the

following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as

H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the

date. If there are two or more United States Treasury securities maturing on the maturity date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more

United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the

Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal

amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the redemption price shall be

conclusive and binding for all purposes, absent manifest error. The Trustee shall not be responsible for calculating the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s

procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. Any redemption or notice described above may, at the Company’s discretion, be subject to the satisfaction or waiver of

one or more conditions precedent. In addition, if such redemption is subject to satisfaction or waiver of one or more conditions precedent, the notice of such redemption shall state that, in the Company’s discretion, the redemption date may be

delayed until such time as any or all such conditions shall be satisfied or waived, or such notice may be rescinded and the redemption terminated in the event that any or all such conditions shall not have been satisfied or waived by the redemption

date, or by the redemption date so delayed. The Company shall notify holders of any such rescission as soon as practicable after the Company determines that such conditions precedent will not be able to be satisfied or the Company is not able or

willing to waive such conditions precedent.

In the case of a partial redemption, selection of the Notes for redemption will be made pro

rata in accordance with the procedures of the Depositary (or another depositary) or by lot. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates

to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation

of the original note. For so long as the Notes are held by The Depository Trust Company, Euroclear Bank SA/ NV, as operator of the Euroclear System, Clearstream Banking, société anonyme or another depositary, the redemption of

the Notes shall be done in accordance with the policies and procedures of the Depositary.

Unless the Company defaults in payment of the

redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

For the avoidance of doubt, neither the Trustee nor any paying agent shall be responsible for performing any calculations or selections in

connection with any optional redemption.

Repurchase Upon a Change of Control

If a Change of Control Triggering Event (as defined below) occurs with respect to the Notes, unless the Company has exercised its option to

redeem the Notes as described above, the Company will be required to make an offer (a “Change of Control Offer”) to each holder of the Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in

excess thereof) of that holder’s Notes on the terms set forth in such Notes. In a Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued

and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control Payment”).

Within 30 days following any such Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control (as

defined below), but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed or electronically delivered, or with respect to Notes held in global form, to the extent permitted or

required by applicable procedures or regulations of the Depositary, sent electronically to holders of the Notes, with a copy to the Trustee under the Indenture that such Notes are being issued under, describing the transaction that constitutes or

may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date will be no earlier than 10 days and (unless delivered in advance of the occurrence of such Change of Control

Triggering Event) no later than 60 days from the date such notice is mailed or sent (a “Change of Control Payment Date”). The notice will, if mailed or sent prior to the date of consummation of the Change of Control, state that

the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring.

On each Change of Control Payment Date, the Company will, to the extent lawful:

•

accept for payment all Notes or portions of Notes properly tendered pursuant to the applicable Change of Control

Offer;

•

deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or

portions of Notes properly tendered; and

following such purchase at a redemption price in cash equal to the applicable Change of Control Payment.
