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 TCM 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 applicable Par Call Date, as applicable.  If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date.

CHANGE OF CONTROL
 
SECTION 4.1 Change of Control.  (a)  If a Change of Control Triggering Event occurs with respect to a series of Notes, unless the Company has exercised its option to redeem such series of Notes by notifying the Holders of such series of Notes to such effect, the Company shall be required to make a Change of Control Offer to each Holder of such series of Notes as to which the Change of Control Triggering Event has occurred to repurchase all or any part (equal to $200,000 or an integral multiple of $1,000 in excess of $200,000) of that Holder’s Notes.  In a Change of Control Offer, the Company shall offer payment in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (a “Change of Control Payment”). Upon the occurrence of a Change of Control Triggering Event, unless all Notes have been called for redemption, each Holder of such series of Notes shall have the right to require the Company to repurchase all or any part (equal to $200,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes at an offer price in cash equal to the Change of Control Payment.
 
-12-
(b)         Within 30 days following any Change of Control Triggering Event, or at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be sent to Holders of such series of Notes, and a copy of such notice shall be delivered to the Trustee, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such series of Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is sent (a “Change of Control Payment Date”).  The notice shall, if 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 with respect to such series of Notes occurring on or prior to the Change of Control Payment Date.  The notice shall state, among other things:
 
(i)           that a Change of Control Triggering Event has occurred or will occur, the date of such event, and that such Holder has the right to require the Company to repurchase such Holder’s Notes;
 
(ii)          the circumstances and relevant facts regarding such Change of Control;
 
(iii)        that the Change of Control Offer is being made pursuant to this Section 4.1 and that all Notes properly tendered pursuant to the Change of Control Offer will be accepted for payment on the Change of Control Payment Date;
 
(iv)         the Change of Control Payment Date;
 
(v)          the Change of Control Payment;
 
(vi)         the name and address of the Paying Agent;
 
(vii)       that the Notes must be surrendered at least five Business Days prior to the Change of Control Payment Date to the Paying Agent at the office of the Paying Agent, together with the form entitled “Option of Holder to Elect Repayment” which form is annexed to the Notes;
 
(viii)       that the Change of Control Payment for any Note which has been properly tendered and not withdrawn will be made promptly following the Change of Control Payment Date;
 
(ix)         that any Note not tendered will continue to accrue interest; and
 
-13-
(x)         that, unless the Company defaults in making the Change of Control Payment, any Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date.
 
A Change of Control Offer may be made at the same time as consents are solicited with respect to an amendment, supplement or waiver of the provisions of this Supplemental Indenture, the Notes and/or the Guarantees; provided that such Change of Control Offer shall not include the delivery of such consents as a condition precedent.
 
(c)         In order to accept the Change of Control Offer the Holder must deliver to the Paying Agent, at least five Business Days prior to the Change of Control Payment Date, the Notes, together with the form entitled “Option to Elect Repayment”, which form is annexed to the Notes, duly completed, setting forth:
 
(i)           the name of the Holder of the Notes;
 
(ii)          the principal amount of the Notes;
 
(iii)         the principal amount of the Notes to be repurchased;
 
(iv)         the certificate number or description of the tenor and terms of the Notes;
 
(v)          a statement that the Holder is accepting the Change of Control Offer; and
 
(vi)       a guarantee that the Notes together with the form entitled “Option to Elect Repayment Form” duly completed will be received by the Paying Agent at least five Business Days prior to the Change of Control Payment Date.
 
Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable.  The Change of Control Offer may be accepted for less than the entire principal amount of a series of Notes but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to $200,000 or an integral multiple of $1,000 in excess thereof.  The Notes which are repurchased only in part (pursuant to the provisions of this Section 4.1) shall be so stated in the applicable “Option to Elect Repayment Form,” and, with respect to Notes represented by physical securities, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of the Notes without service charge, a new Note or Notes of the same series and tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Notes.
 
(d)          On each Change of Control Payment Date, the Company shall, to the extent lawful:
 
(i)     accept for payment all Notes or portions of such Notes properly tendered pursuant to the applicable Change of Control Offer;

(ii)    deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all such Notes or portions of such Notes properly tendered; and

-14-
(iii)  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 the Notes or portions of the Notes being repurchased and that all conditions precedent provided for in this Supplemental Indenture to the Change of Control Offer and to the repurchase by the Company of the Notes pursuant to the Change of Control Offer have been met.

(e)         The Company shall 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 of this Section 4.1 and the third party repurchases all Notes properly tendered and not withdrawn under its offer.  In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under this Supplemental Indenture with respect to such series of Notes, other than a default in the payment of the Change of Control Payment upon a related Change of Control Triggering Event.
 
(f)         The Company shall comply with the requirements of Rule 14e-1 under 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 related 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 shall comply with those securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.1 by virtue of any such conflict.

(2)
100% of the principal amount of the Notes to be redeemed

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.
 
The Securities shall have the benefit of the Guarantee of the Guarantors on the terms set forth therein.
 
The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Security upon compliance with certain conditions set forth in the Indenture.
 
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
 
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of at least a majority in principal amount of the Securities at the time Outstanding of each series to be affected.

Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
 
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 30% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
 
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.
 
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Securities of this series are subject to redemption upon not less than 10, but not more than 60, days’ notice, at any time, as a whole or in part, at the election of the Company. If this Security is redeemed by the Company before the 2056 Par Call Date, it will be redeemed in accordance with the terms of the Indenture, at the greater of the following amounts:

(2)
100% of the principal amount of the Notes to be redeemed

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
 
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 30% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
 
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable.  The Change of Control Offer may be accepted for less than the entire principal amount of a series of Notes but in that event the principal amount of the Notes remaining outstanding after repurchase must be equal to €100,000 or an integral multiple of €1,000 in excess thereof.  The Notes which are repurchased only in part (pursuant to the provisions of this Section 4.1) shall be so stated in the applicable “Option to Elect Repayment Form,” and, with respect to Notes represented by physical securities, the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of the Notes without service charge, a new Note or Notes of the same series and tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unrepurchased portion of the principal of the Notes.
 
(d)          On each Change of Control Payment Date, the Company shall, to the extent lawful:
 
(i)           accept for payment all Notes or portions of such Notes properly tendered pursuant to the applicable Change of Control Offer;
 
(ii)         deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all such Notes or portions of such Notes properly tendered; and

(e)         The Company shall 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 of this Section 4.1 and the third party repurchases all Notes properly tendered and not withdrawn under its offer.  In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under this Supplemental Indenture with respect to such series of Notes, other than a default in the payment of the Change of Control Payment upon a related Change of Control Triggering Event.
 
(f)        The Company shall comply with the requirements of Rule 14e-1 under 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 related 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 shall comply with those securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.1 by virtue of any such conflict.

Reverse of Security
 
EATON CAPITAL UNLIMITED COMPANY
 
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of May 9, 2025 (herein called the “Base Indenture”), among the Company, Eaton Corporation plc, Cooper B-Line, Inc., Cooper Bussmann, LLC, Cooper Crouse-Hinds, LLC, Cooper Industries Unlimited Company, Cooper Power Systems, LLC, Cooper Wiring Devices, Inc., Eaton Aeroquip LLC, Eaton Aerospace LLC, Eaton Controls (Luxembourg) S.à r.l., Eaton Corporation, Eaton Domhanda Unlimited Company, Eaton Electric Holdings LLC, Eaton Filtration LLC, Eaton Leasing Corporation, Eaton Technologies (Luxembourg) S.à r.l., Turlock B.V. and Wright Line LLC (together, the “Guarantors”); 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), as supplemented by the Fourth Supplemental Indenture, dated as of March 10, 2026 (the Base Indenture, as so supplemented, herein called the “Indenture”), among the Company, the Guarantors and the Trustee, 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 Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.
 
The Securities of this series are subject to redemption upon not less than 10, but not more than 60, days’ notice, at any time, as a whole or in part, at the election of the Company. If this Security is redeemed by the Company before the 2034 Par Call Date, it will be redeemed in accordance with the terms of the Indenture, at the greater of the following amounts:
 

 (1)
(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the 2034 Par Call Date) on an annual basis (assuming an Actual/Actual (ICMA) day count fraction) at the Comparable Government Bond Rate, plus 15 basis points, less (b) interest accrued to the date of redemption, and
 

 (2)
100% of the principal amount of the Notes to be redeemed
 
plus, in either case, accrued and unpaid interest thereon to the redemption date.
 
The Trustee shall have no obligation with respect to the determination of the redemption price.
 
If this Security is redeemed by the Company on or after the 2034 Par Call Date, this Security will be redeemed by the Company at an amount equal to 100% of the principal amount of the Securities to be so redeemed, plus accrued and unpaid interest on such Securities to, but excluding, the redemption date.
 
Upon the occurrence of a Change of Control Triggering Event, unless all Securities have been called for redemption pursuant to the provision described above, each Holder of Securities of this series shall have the right to require the Company to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 in excess thereof) of such Securities at an offer price in cash equal to the Change of Control Payment.
 
A-5
In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.
 
The Securities shall have the benefit of the Guarantee of the Guarantors on the terms set forth therein.
 
The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Security upon compliance with certain conditions set forth in the Indenture.
 
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
 
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of at least a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. The term “Holder” shall include the persons for the time being shown in the records of Euroclear and/or Clearstream, as the holders of a particular principal amount of the applicable series of Notes (in which regard a certificate or other document issued by Euroclear or Clearstream as to the principal amount of such Notes standing to the account of any person shall be conclusive and binding) for all purposes other than with respect to the payment of principal and interest on such Notes, the right to which shall be vested as against the Issuer solely in the registered holder of the Global Note in accordance with and subject to its terms. The term “Notes” shall mean units of €1,000 principal amount of such Notes.
 
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 30% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
 
A-6
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
 
As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
 
The Securities of this series are issuable only in registered form without coupons in denominations of €100,000 or an integral multiple of €1,000 in excess of €100,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.
 
This Security may be exchanged in whole but not in part (free of charge) for definitive registered Securities (“Definitive Notes”) of like tenor in minimum denominations of €100,000 principal amount and integral multiples of €1,000 in excess thereof only upon (i) the occurrence of an Exchange Event or (ii) an event of default with respect to the Securities will have occurred and be continuing. An “Exchange Event” shall occur if Euroclear or Clearstream notifies the Company that it is unwilling or unable to continue to act as depositary and a successor depositary is not appointed by the Company within 90 days. The Company will promptly give notice to Holders in accordance with the Indenture upon the occurrence of an Exchange Event. In the event of the occurrence of any Exchange Event, Euroclear and/or Clearstream or any person acting on their behalf, acting on the instructions of any holder of an interest in this Security, may give written notice to the Security Registrar requesting exchange. Any exchange shall occur no later than 10 days after the date of receipt of the relevant notice by the Security Registrar. Exchanges will be made upon presentation of this Security at the office of the Security Registrar at 2-4 r. Eugène Ruppert, 2453 Luxemburg, Luxembourg by the holder of it on any day (other than a Saturday or Sunday) on which banks are open for general business in Luxembourg. The aggregate principal amount of Definitive Notes issued upon an exchange of this Security will be equal to the aggregate principal amount of this Security. On an exchange in whole of this Security, this Security shall be surrendered to the Security Registrar for cancellation. On any exchange or transfer following which either (i) Notes represented by this Security are no longer to be so represented or (ii) details of the transfer of Notes not so represented shall be entered by the Security Registrar in the Security Register, the principal amount of this Security shall be increased or reduced (as the case may be) by the principal amount so transferred. Until the exchange of the whole of this Security, the registered holder of this Security shall in all respects (except as otherwise provided in this Security) be entitled to the same benefits as if such person were the registered holder of the Definitive Notes represented by this Security.
 
A-7
All notices to the Holders will be valid if mailed to them at their respective address in the register of holders maintained in relation to the Notes or given in accordance with the procedures of Euroclear and Clearstream.
 
Ownership of interests in this Security (the “Book-Entry Interests”) are limited to persons that have accounts (participants) with a Clearing Agency or persons that hold interests through such participants. The Clearing Agencies hold interests in this Security on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. Except under the limited circumstances set forth above, Book-Entry Interests will not be held in definitive certificated form.
 
In the event this Security (or any portion hereof) is redeemed, Euroclear and/or Clearstream, as applicable, will redeem an equal amount of the Book-Entry Interests in this Security from the amount received by it in respect of the redemption of this Security. The redemption price payable in connection with the redemption of such Book-Entry Interests will be equal to the amount received by Euroclear and Clearstream, as applicable, in connection with the redemption of this Security (or any portion hereof).
 
If fewer than all of the Notes are to be redeemed at any time, Euroclear and Clearstream will credit their respective participants’ accounts on a proportionate basis (with adjustments to prevent fractions), by either a pool factor or a reduction in principal amount, at their discretion, or on such other basis as they deem fair and appropriate under the existing practices of Euroclear and Clearstream; provided, however, that no Book-Entry Interest of €100,000 principal amount or less may be redeemed in part.
 
So long as the Notes are held in global form by the Common Safekeeper, participants must rely on the procedures of Euroclear and/or Clearstream and indirect participants must rely on the procedures of Euroclear, Clearstream and the participants through which they own Book-Entry Interests, to transfer their interests or to exercise any rights of holders under the Notes and/or the Indenture.
 
None of the Company, the Guarantors, the Security Registrar, the Trustee or the Paying Agent has any responsibility, nor are they liable, for any aspect of the records relating to the Book-Entry Interests.
 
In the event this Security (or any portion hereof) is redeemed, Euroclear and/or Clearstream, as applicable, will redeem an equal amount of the Book-Entry Interests in this Security from the amount received by it in respect of the redemption of this Security. The redemption price payable in connection with the redemption of such Book-Entry Interests will be equal to the amount received by Euroclear and Clearstream, as applicable, in connection with the redemption of this Security (or any portion hereof). If fewer than all of the Notes are to be redeemed at any time, Euroclear and Clearstream will credit their respective participants’ accounts on a proportionate basis (with adjustments to prevent fractions), by either a pool factor or a reduction in principal amount, at their discretion, or on such other basis as they deem fair and appropriate under the existing practices of Euroclear and Clearstream; provided, however, that no Book-Entry Interest of €100,000 principal amount or less may be redeemed in part.
 
A-8
This certifies that the person whose name is entered in the Security Register is registered as the Holder of the aggregate nominal amount of €600,000,000 of the Notes, being all the Notes represented by this Security.
 
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
 
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered in the Security Register as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
 
All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
 
THIS SECURITY WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

EATON CAPITAL UNLIMITED COMPANY
 
This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of May 9, 2025 (herein called the “Base Indenture”), among the Company, Eaton Corporation plc, Cooper B-Line, Inc., Cooper Bussmann, LLC, Cooper Crouse-Hinds, LLC, Cooper Industries Unlimited Company, Cooper Power Systems, LLC, Cooper Wiring Devices, Inc., Eaton Aeroquip LLC, Eaton Aerospace LLC, Eaton Controls (Luxembourg) S.à r.l., Eaton Corporation, Eaton Domhanda Unlimited Company, Eaton Electric Holdings LLC, Eaton Filtration LLC, Eaton Leasing Corporation, Eaton Technologies (Luxembourg) S.à r.l., Turlock B.V. and Wright Line LLC (together, the “Guarantors”); 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), as supplemented by the Fourth Supplemental Indenture, dated as of March 10, 2026 (the Base Indenture, as so supplemented, herein called the “Indenture”), among the Company, the Guarantors and the Trustee, 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 Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered.
 
The Securities of this series are subject to redemption upon not less than 10, but not more than 60, days’ notice, at any time, as a whole or in part, at the election of the Company. If this Security is redeemed by the Company before the 2038 Par Call Date, it will be redeemed in accordance with the terms of the Indenture, at the greater of the following amounts:
 

 (1)
(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the 2038 Par Call Date) on an annual basis (assuming an Actual/Actual (ICMA) day count fraction) at the Comparable Government Bond Rate, plus 20 basis points, less (b) interest accrued to the date of redemption, and
 

 (2)
100% of the principal amount of the Notes to be redeemed
 
plus, in either case, accrued and unpaid interest thereon to the redemption date.
 
The Trustee shall have no obligation with respect to the determination of the redemption price.
 
If this Security is redeemed by the Company on or after the 2038 Par Call Date, this Security will be redeemed by the Company at an amount equal to 100% of the principal amount of the Securities to be so redeemed, plus accrued and unpaid interest on such Securities to, but excluding, the redemption date.
 
Upon the occurrence of a Change of Control Triggering Event, unless all Securities have been called for redemption pursuant to the provision described above, each Holder of Securities of this series shall have the right to require the Company to repurchase all or any part (equal to €100,000 or an integral multiple of €1,000 in excess thereof) of such Securities at an offer price in cash equal to the Change of Control Payment.
 
B-5
In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.
 
The Securities shall have the benefit of the Guarantee of the Guarantors on the terms set forth therein.
 
The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Security upon compliance with certain conditions set forth in the Indenture.
 
If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.
 
The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of at least a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. The term “Holder” shall include the persons for the time being shown in the records of Euroclear and/or Clearstream, as the holders of a particular principal amount of the applicable series of Notes (in which regard a certificate or other document issued by Euroclear or Clearstream as to the principal amount of such Notes standing to the account of any person shall be conclusive and binding) for all purposes other than with respect to the payment of principal and interest on such Notes, the right to which shall be vested as against the Issuer solely in the registered holder of the Global Note in accordance with and subject to its terms. The term “Notes” shall mean units of €1,000 principal amount of such Notes.
 
As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 30% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.
 
B-6
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
 
As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.
 
The Securities of this series are issuable only in registered form without coupons in denominations of €100,000 or an integral multiple of €1,000 in excess of €100,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.
 
This Security may be exchanged in whole but not in part (free of charge) for definitive registered Securities (“Definitive Notes”) of like tenor in minimum denominations of €100,000 principal amount and integral multiples of €1,000 in excess thereof only upon (i) the occurrence of an Exchange Event or (ii) an event of default with respect to the Securities will have occurred and be continuing. An “Exchange Event” shall occur if Euroclear or Clearstream notifies the Company that it is unwilling or unable to continue to act as depositary and a successor depositary is not appointed by the Company within 90 days. The Company will promptly give notice to Holders in accordance with the Indenture upon the occurrence of an Exchange Event. In the event of the occurrence of any Exchange Event, Euroclear and/or Clearstream or any person acting on their behalf, acting on the instructions of any holder of an interest in this Security, may give written notice to the Security Registrar requesting exchange. Any exchange shall occur no later than 10 days after the date of receipt of the relevant notice by the Security Registrar. Exchanges will be made upon presentation of this Security at the office of the Security Registrar at 2-4 r. Eugène Ruppert, 2453 Luxemburg, Luxembourg by the holder of it on any day (other than a Saturday or Sunday) on which banks are open for general business in Luxembourg. The aggregate principal amount of Definitive Notes issued upon an exchange of this Security will be equal to the aggregate principal amount of this Security. On an exchange in whole of this Security, this Security shall be surrendered to the Security Registrar for cancellation. On any exchange or transfer following which either (i) Notes represented by this Security are no longer to be so represented or (ii) details of the transfer of Notes not so represented shall be entered by the Security Registrar in the Security Register, the principal amount of this Security shall be increased or reduced (as the case may be) by the principal amount so transferred. Until the exchange of the whole of this Security, the registered holder of this Security shall in all respects (except as otherwise provided in this Security) be entitled to the same benefits as if such person were the registered holder of the Definitive Notes represented by this Security.
 
B-7
All notices to the Holders will be valid if mailed to them at their respective address in the register of holders maintained in relation to the Notes or given in accordance with the procedures of Euroclear and Clearstream.
 
Ownership of interests in this Security (the “Book-Entry Interests”) are limited to persons that have accounts (participants) with a Clearing Agency or persons that hold interests through such participants. The Clearing Agencies hold interests in this Security on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. Except under the limited circumstances set forth above, Book-Entry Interests will not be held in definitive certificated form.
 
In the event this Security (or any portion hereof) is redeemed, Euroclear and/or Clearstream, as applicable, will redeem an equal amount of the Book-Entry Interests in this Security from the amount received by it in respect of the redemption of this Security. The redemption price payable in connection with the redemption of such Book-Entry Interests will be equal to the amount received by Euroclear and Clearstream, as applicable, in connection with the redemption of this Security (or any portion hereof).
 
If fewer than all of the Notes are to be redeemed at any time, Euroclear and Clearstream will credit their respective participants’ accounts on a proportionate basis (with adjustments to prevent fractions), by either a pool factor or a reduction in principal amount, at their discretion, or on such other basis as they deem fair and appropriate under the existing practices of Euroclear and Clearstream; provided, however, that no Book-Entry Interest of €100,000 principal amount or less may be redeemed in part.
 
So long as the Notes are held in global form by the Common Safekeeper, participants must rely on the procedures of Euroclear and/or Clearstream and indirect participants must rely on the procedures of Euroclear, Clearstream and the participants through which they own Book-Entry Interests, to transfer their interests or to exercise any rights of holders under the Notes and/or the Indenture.
 
None of the Company, the Guarantors, the Security Registrar, the Trustee or the Paying Agent has any responsibility, nor are they liable, for any aspect of the records relating to the Book-Entry Interests.
 
In the event this Security (or any portion hereof) is redeemed, Euroclear and/or Clearstream, as applicable, will redeem an equal amount of the Book-Entry Interests in this Security from the amount received by it in respect of the redemption of this Security. The redemption price payable in connection with the redemption of such Book-Entry Interests will be equal to the amount received by Euroclear and Clearstream, as applicable, in connection with the redemption of this Security (or any portion hereof). If fewer than all of the Notes are to be redeemed at any time, Euroclear and Clearstream will credit their respective participants’ accounts on a proportionate basis (with adjustments to prevent fractions), by either a pool factor or a reduction in principal amount, at their discretion, or on such other basis as they deem fair and appropriate under the existing practices of Euroclear and Clearstream; provided, however, that no Book-Entry Interest of €100,000 principal amount or less may be redeemed in part.
 
B-8
This certifies that the person whose name is entered in the Security Register is registered as the Holder of the aggregate nominal amount of €600,000,000 of the Notes, being all the Notes represented by this Security.
 
No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
 
Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered in the Security Register as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.
 
All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
 
THIS SECURITY WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

Ladies and Gentlemen:
 
As Counsel, Vice President and Assistant Secretary of Eaton Corporation, an Ohio corporation, and Vice President and Secretary of Eaton Aeroquip LLC, an Ohio limited liability company, and Eaton Leasing Corporation, an Ohio corporation (together, the “Opinion Parties”), I, or attorneys who I supervise, have acted and am furnishing this opinion in connection with the preparation and filing under the Securities Act of 1933, as amended (the “Securities Act”), with the Securities and Exchange Commission (the “Commission”) of (i) a registration statement on Form S-3ASR (File No. 333-281174) on August 1, 2024 (the “Registration Statement”), (ii) a Prospectus, dated August 1, 2024, forming part of the Registration Statement (the “Base Prospectus”), and (iii) a prospectus supplement, dated March 4, 2026, filed pursuant to Rule 424(b) under the Securities Act (the “Prospectus Supplement” and, together with the Base Prospectus, the “Prospectus”) relating to the issuance and sale by Eaton Corporation, an Ohio corporation (the “Issuer”), of $1,500,000,000 in aggregate principal amount of the Issuer’s 3.850% Notes due 2028 (the “2028 Notes”), $1,500,000,000 in aggregate principal amount of the Issuer’s 3.950% Notes due 2029 (the “2029 Notes”), $1,500,000,000 in aggregate principal amount of the Issuer’s 4.200% Notes due 2031 (the “2031 Notes”), $1,000,000,000 in aggregate principal amount of the Issuer’s 4.500% Notes due 2033 (the “2033 Notes”), $2,000,000,000 in aggregate principal amount of the Issuer’s 4.800% Notes due 2036 (the “2036 Notes”), and $1,000,000,000 in aggregate principal amount of the Issuer’s 5.450% Notes due 2056 (the “2056 Notes” and, collectively with the 2028 Notes, the 2029 Notes, the 2031 Notes, the 2033 Notes, and the 2036 Notes, the “Notes”) and the guarantees of the Notes (the “Guarantees”) by the guarantors party thereto. The Notes are being issued pursuant to an indenture, dated as of May 9, 2025 (the “Base Indenture”), among the Issuer, the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the third supplemental indenture, dated as of the date hereof, among the Issuer, the guarantors party thereto and the Trustee (the Base Indenture, as so supplemented, the “Indenture”). In connection with the issuance and sale of the Notes, the Issuer, the guarantors party thereto and Barclays Capital Inc., BofA Securities, Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, as representatives of the several underwriters named therein (collectively, the “Underwriters”), entered into an Underwriting Agreement, dated March 4, 2026 (the “Underwriting Agreement”), attached to the Terms Agreement, dated March 4, 2026 (together with the Underwriting Agreement, the “Terms Agreement”).
 
I have examined such corporate records of the Opinion Parties and such other documents and certificates as I have deemed necessary as a basis for the opinions hereinafter expressed. Based on the foregoing and subject to the qualifications, assumptions and limitations stated herein, having regard for such legal considerations as I have deemed relevant, I am of the opinion that, under the laws of the state of Ohio:
 

 1.
Each Opinion Party is a corporation or limited liability company, as applicable, duly incorporated or formed, as applicable, validly existing and in good standing under the laws of Ohio and has all requisite corporate or limited liability company power, as applicable, to execute and deliver, and to perform its obligations under, the Indenture, the Notes and the Guarantees (collectively, the “Transaction Documents”) to which it is a party.
 

 2.
The Indenture has been duly authorized, executed and delivered by each Opinion Party.
 

 3.
The Guarantees have been duly authorized, executed and delivered by each Opinion Party.
 
I am a member of the Bar of the State of Ohio and do not purport to be an expert on, or to express any opinion herein concerning, any laws other than the laws of the State of Ohio and the federal laws of the United States. Accordingly, I do not express any opinion as to the laws of any other jurisdiction. The opinions expressed above are limited to the matters stated in this opinion letter, and no opinion is implied or may be inferred beyond those expressly stated in this opinion letter.

I am a member of the Bar of the State of Ohio and do not purport to be an expert on, or to express any opinion herein concerning, any laws other than the laws of the State of Ohio and the federal laws of the United States. Accordingly, I do not express any opinion as to the laws of any other jurisdiction. The opinions expressed above are limited to the matters stated in this opinion letter, and no opinion is implied or may be inferred beyond those expressly stated in this opinion letter.

The opinions expressed above are as of the date hereof only, and I express no opinion as to, and assume no responsibility for, the effect of any fact or circumstance occurring, or of which I learn, subsequent to the date of this opinion letter, including, without limitation, legislative and other changes in the law or changes in circumstances affecting any party.

1.
Introduction
 
1.1
We have acted as special legal counsel in Ireland to the Companies in connection with certain Irish law matters relating to the entry into of the Documents by the Companies.
 
1.2
We are qualified to give this legal opinion under Irish law on the bases, under the assumptions, and subject to the reservations and qualifications set out below.

2.
Bases of Opinion
 
2.1
This Opinion speaks only as of its date. We assume no obligation to update this Opinion at any time in the future or to advise you or any person of any change in law, change in regulation, change in interpretation of law or regulation or change in the practices of the Irish Revenue Commissioners which may occur after the date of this Opinion.
 
2.2
For the purposes of giving this Opinion we have examined original, facsimile or electronic copies of:
 

 (a)
the executed Documents;
 

 (b)
a certificate of an authorised officer of each Company dated 4 March 2026 (the “Certificates”), attaching (as applicable):

each authorising and approving the entry into the Documents;
 

 (c)
results of searches made by independent law searchers on our behalf against the Companies on 5 March 2026 in:
 

 (i)
the Companies Registration Office;
 

 (ii)
the Petitions Section of the Central Office of the High Court of Ireland; and
 

 (iii)
the Judgments Office of the Central Office of the High Court of Ireland,
 
(together, the “Searches”, copies of which are attached to this Opinion); and
 

 (d)
all other relevant corporate documents of each Company and such further documents and matters of law as we have considered necessary or appropriate for the preparation of this Opinion.
 
2.3
In this Opinion:
 
“Act” means the Companies Act 2014;
 
Page 2/15
“courts” means the courts of Ireland, unless otherwise indicated, and “court” shall be construed accordingly;
 
“Documents” means the documents listed in the Schedule hereto;
 
“Prospectus” means the supplemental prospectus dated 4 March 2026 relating to the offering of the Notes;
 
“Parties” means, in respect of each of the Documents, the parties to that Document and “Party” means any of them;
 
“Registration Statement” means the Form S-3 filed with the SEC on 1 August 2024 by the Parent;
 
“SEC” means the Securities and Exchange Commission;
 
“Transactions” means the obligations and transactions contemplated by the Documents or any of such obligations and transactions, as the context requires or permits; and
 
“Underwriters” means the parties named in the Terms Agreement.
 
2.4
Initially capitalised terms used in this Opinion but not defined herein have the meanings given to them in the Documents.
 
2.5
This Opinion is governed by, and interpreted in accordance with, Irish law.
 
2.6
This Opinion is limited to the matters expressly stated in this letter only.  In particular:
 

 (a)
save as expressly stated herein, we express no advice on the effect, validity, or enforceability of or the creation or effectiveness of any document;
 

 (b)
we express no advice on the contractual terms of any document other than by reference to the legal character thereof under the laws of Ireland;
 

 (c)
we have made no investigation of, and express no advice on, the laws, or the effect on the Documents and the Transactions of the laws, of any country or jurisdiction other than Ireland, and this Opinion is strictly limited to the laws of Ireland as in force on the date hereof and as currently applied by the courts (excluding any foreign law to which reference may be made under the rules of Irish private international law).  We have assumed without investigation that, insofar as the laws of any jurisdiction other than Ireland are relevant, such laws do not prohibit and are not inconsistent with any of the obligations or rights expressed in the Documents or the Transactions; and

the Certificates and the statements made therein, together with the attachments thereto, and this Opinion is expressly given upon the terms that the information disclosed thereby has not changed since the date thereof and that no further investigation or diligence whatsoever in respect of any matter referred to, or the statements made, in a Certificate (or in the attachments thereto) is required of us by you; and
 

 (b)
the results of the Searches.
 
2.9
It should be noted that the Documents contain express references to provisions of statutes and the law of jurisdictions other than Ireland and we express no opinion on any such provision or its application to the Documents or to any Company. We have proceeded on the basis that words and phrases used in the Documents to describe the laws and practices of such other jurisdictions have the same meaning and effect as if they were governed by Irish law.  Accordingly, our opinion must be regarded as being qualified to the extent that, if this basis is incorrect, we would have found it necessary or appropriate to include further assumptions and/or qualifications.
 
2.10
We consent to the filing of this Opinion with the SEC as an exhibit to a current report on Form 8-K and its incorporation by reference into the Registration Statement and to the reference to our firm contained under the heading “Legal Opinions” in the Prospectus included therein.

Opinion
 
Subject to:
 

 (a)
the bases of opinion set out in paragraph 2 above;
 

 (b)
the assumptions and reservations set out in paragraphs 4 and 5, respectively, below; and
 

 (c)
any matters or documents not disclosed to us,
 
we are of the opinion as follows:
 
3.1
Corporate Status
 
The Parent is a public limited company having a share capital and is duly incorporated under the laws of Ireland.  It is incorporated for an indefinite period, is a separate legal entity and is subject to suit in its own name.
 
Page 4/15
Eaton Capital is a public unlimited company having a share capital and is duly incorporated under the laws of Ireland.  It is incorporated for an indefinite period, is a separate legal entity and is subject to suit in its own name.
 
Each of Cooper Industries and Eaton Domhanda are private unlimited companies having a share capital and are duly incorporated under the laws of Ireland.  They are incorporated for an indefinite period, are separate legal entities and are subject to suit in their own name.
 
The Searches do not disclose that any steps have been taken to appoint an examiner to any Company, to appoint a receiver to any Company or its assets or to wind it up.  On the basis of the Searches only, each of the Companies is validly existing.
 
3.2
Capacity and Authority of the Companies
 
Each Company has the necessary legal capacity to enter into, deliver and perform its obligations under the Documents to which it is a party. All necessary corporate action required on the part of each Company to authorise the execution and delivery of the Documents to which it is party and the performance by it of its obligations under the Documents to which it is party has been duly taken.
 
3.3
Due execution
 
Each Company has validly executed the Documents to which it is a party.
 
3.4
Documents: No breach of constitutional documents/laws
 
The execution and delivery by each Company of the Documents to which it is a party and the performance by it of its obligations under the Documents to which it is a party will not violate the Constitution of such Company or any law or regulation of general application in Ireland applicable to such Company.
 
3.5
Registrations/filings
 
No registration, filing, notarisation or recording of the Documents is necessary under the laws of Ireland as a condition of the legality, validity, admissibility in evidence or enforceability of the Documents in Ireland.
 
3.6
Official Authorisations
 
Based on our review of those laws and regulations which are normally applicable to transactions of the type contemplated by the Documents, the execution and delivery by each Company of the Documents to which it is a party and the performance by each Company of its obligations under the Documents to which it is a party, will not require on the part of such Company any consent, exemption, licence, approval or authorisation of any governmental or regulatory body or official of Ireland.
 
Page 5/15
3.7
Governing law
 
Council Regulation (EC) No. 593/2008 of 17 June 2008 on the law applicable to contractual obligations, as amended by Corrigendum to Regulation (EC) No 593/2008 of the European Parliament and of the Council of 17 June 2008 on the law applicable to contractual obligations (Rome I) (“Rome I”) has force of law in Ireland. The incorporation of the laws of the State of New York, as the governing law of contractual obligations arising out of the Documents is, in respect of contractual obligations which are within the scope of Rome I, valid in accordance with Article 3(1) of Rome I and accordingly, subject to and in accordance with Rome I, the laws of the State of New York will, upon proof of the relevant provisions of the relevant laws, be applied by the courts if any claim to enforce such contractual obligations against any Company party to the Documents come under their jurisdiction.
 
Council Regulation (EC) No. 864/2007 of 11 July 2007 on the law applicable to non-contractual obligations (“Rome II”) has force of law in Ireland.  The incorporation of the laws of the State of New York, as the governing law of non-contractual obligations arising out of the Documents is, in respect of non-contractual obligations which are within the scope of Rome II, valid in accordance with Article 14(1) of Rome II and accordingly, subject to and in accordance with Rome II, the laws of the State of New York will, upon proof of the relevant provisions of the relevant laws, be applied by the courts if any claim to enforce such non-contractual obligations against any Company party to the Documents comes under their jurisdiction.
 
3.8
Submission to jurisdiction
 
Any submission by a Company in the Documents to which it is a party to the jurisdiction of any New York or any federal court sitting in the Borough of Manhattan, The City of New York (together, the “New York Courts”) is legally valid, binding and enforceable against such Company under the laws of Ireland.
 
3.9
Enforcement of judgments
 
Any judgment in relation to any or all of the Documents obtained in the State of New York against a Company would be recognised and enforced in Ireland without re-trial or examination of the merits of the case provided that:
 

 (a)
the judgment has not been obtained or alleged to have been obtained by fraud or a trick;
 

 (b)
the decision of the New York court and the enforcement thereof was not and would not be contrary to natural or constitutional justice under Irish law;
 

 (c)
the enforcement of the judgment would not be contrary to public policy as understood by the courts or constitute the enforcement of a judgment of a penal or revenue nature or be inconsistent with a judgment of the courts in respect of the same matter;
 

 (d)
the judgment is final and conclusive and is for a debt or definite sum of money;
 

 (e)
the procedural rules of the New York court and the courts have been observed; and
 

 (f)
the jurisdiction of the New York courts had been exercised in circumstances which, as a matter of Irish law, an Irish court will recognise as justifying enforcement of the judgment.

5.
Reservations and Qualifications
 
Our Opinion is subject to the following reservations and qualifications:
 
5.1
Notwithstanding any provision in the Documents to the contrary, the Documents may be capable of being amended by oral agreement or conduct of the Parties.
 
5.2
Provisions in the Documents imposing additional obligations in the event of breach or default, or of payment or repayment being made other than on an agreed date, may be unenforceable to the extent that they are subsequently adjudicated to be penal in nature.  The fact that any payment is held to be penal in nature would not, of itself, prejudice the legality or validity of any other provision contained in the Documents which does not provide for the making of such payment.
 
5.3
Provisions in the Documents that calculations or certifications or acknowledgements are to be conclusive and binding will not necessarily prevent judicial enquiry by the courts into the merits of any claim by a party claiming to be aggrieved by such calculations, certifications or acknowledgements; nor do such provisions exclude the possibility of such calculations, certifications or acknowledgements being amended by order of the courts.
 
5.4
To the extent that the Documents vest a discretion in any party, or provide for any party determining any matter in its opinion, the exercise of such discretion and the manner in which such opinion is formed and the grounds on which it is based may be the subject of a judicial enquiry and review by the courts.
 
5.5
Provisions of the Documents providing for severance of provisions due to illegality, invalidity or unenforceability thereof may not be effective, depending on the nature of the illegality, invalidity or unenforceability in question.
 
5.6
The effectiveness of terms of documents exculpating a party from a liability, obligation or duty otherwise owed is limited by law.
 
Page 12/15
5.7
The description of obligations as “enforceable” or “binding” refers to the legal character of the obligations in question.  It implies no more than that they are of a character which Irish law recognises and enforces.  It does not mean that the Documents will be binding or enforced in all circumstances or that any particular remedy will be available.  Equitable remedies, such as specific performance and injunctive relief, are at the discretion of the courts and may not be available to persons seeking to enforce provisions of the Documents.  Furthermore, the courts may not allow acceleration of amounts payable under the Documents where an event of default occurs that is considered immaterial.  More generally, in any proceedings to enforce the Documents, the courts may require that the Party seeking enforcement acts with reasonableness and good faith.  Enforcement of the Documents may also be limited as a result of (a) the provisions of Irish law applicable to contracts held to have become frustrated by events happening after their execution; and (b) any breach of the terms of the Documents by the Party seeking to enforce the same.
 
5.8
The obligations of each Party under the Documents are subject to all laws relating to insolvency, bankruptcy, liquidation, reorganisation, moratorium, examinership, trust schemes, preferential creditors, fraudulent transfer and other similar laws relating to or affecting creditors’ rights generally.
 
5.9
Where an obligation is to be performed outside Ireland under the Documents, it may not be enforceable in Ireland to the extent that performance would be illegal or contrary to public policy under the laws of that jurisdiction.
 
5.10
Any judgment of the courts for moneys due under the Documents may be expressed in a currency other than euro but the order may issue out of the Central Office of the High Court expressed in euro by reference to the official rate of exchange prevailing on the date of issue.  In addition, in a winding-up in Ireland of an Irish incorporated company, all foreign currency claims must be converted into an Irish currency for the purposes of proof.  The rate of exchange to be used to convert foreign currency debts into euro for the purposes of proof in a winding-up is the spot rate as of, in the case of a compulsory winding-up, either the date of commencement of the winding-up (presentation of the petition for winding-up or earlier resolution for winding-up) or of the winding-up order and, in the case of a voluntary winding-up, on the date of the relevant winding-up resolution.
 
5.11
A court may refuse to give effect to a purported contractual obligation to pay costs arising from unsuccessful litigation brought against a party and may not award by way of costs all of the expenditure incurred by a successful litigator in proceedings before that court.
 
5.12
Claims against any Party may be or become the subject of set-off or counterclaim and any waiver of those or other defences available to each Party may not be enforceable in all circumstances.
 
5.13
Currency indemnities contained in the Documents may not be enforceable in all circumstances.
 
5.14
We express no opinion on how courts outside Ireland would apply the laws of Ireland in relation to any aspect of the Documents.
 
5.15
The courts will not decline any mandatory jurisdiction arising pursuant to Council Regulation (EC) No. 1215/2012 of 12 December 2012 on Jurisdiction and the Recognition and Enforcement of Judgments in Civil and Commercial Matters.
 
5.16
Claims against any Party may become barred under relevant statutes of limitation if not pursued within the time limited by such statutes.
 
Page 13/15
5.17
We have not been responsible for investigating or verifying the accuracy of the facts, including statements of law, or the reasonableness of any statement of opinion contained in the Prospectus or that no material information has been omitted therefrom.
 
5.18
The failure of the Searches to reveal evidence that any Company has passed a voluntary winding-up resolution, that a petition has been presented or order made by a court for the winding-up of, or appointment of an examiner to any Company or that a receiver or similar officer has been appointed in relation to any of its assets or revenues is not conclusive proof that no such event has occurred, in particular:
 

 (a)
the Searches may not have revealed whether a petition for winding-up or the appointment of any examiner had been presented;
 

 (b)
notice of a resolution passed, a winding-up order made or the appointment of a receiver or examiner may not have been filed at the Companies Registration Office, Dublin immediately;
 

 (c)
searches have not been undertaken in any Office of the Circuit Court, notwithstanding that the Circuit Court has jurisdiction with respect to the examinership of certain companies; and
 

 (d)
the position may have changed since the time the Searches were made.
 
Yours faithfully

2.5
This Opinion is governed by, and interpreted in accordance with, Irish law.
 
2.6
This Opinion is limited to the matters expressly stated in this letter only.  In particular:
 

 (a)
save as expressly stated herein, we express no advice on the effect, validity, or enforceability of or the creation or effectiveness of any document;
 

 (b)
we express no advice on the contractual terms of any document other than by reference to the legal character thereof under the laws of Ireland;
 

 (c)
we have made no investigation of, and express no advice on, the laws, or the effect on the Documents and the Transactions of the laws, of any country or jurisdiction other than Ireland, and this Opinion is strictly limited to the laws of Ireland as in force on the date hereof and as currently applied by the courts (excluding any foreign law to which reference may be made under the rules of Irish private international law).  We have assumed without investigation that, insofar as the laws of any jurisdiction other than Ireland are relevant, such laws do not prohibit and are not inconsistent with any of the obligations or rights expressed in the Documents or the Transactions; and

Page 3/16
2.7
For the purposes of this Opinion, we have not examined any documents relating to the Transactions other than those documents set out in paragraph 2.2.  Furthermore, we have not examined any other drafts and/or copies of contracts, documents or other instruments affecting any Company or any other person and any other corporate or other records of any Company or any other person, other than as stated in this Opinion.

2.9
It should be noted that the Documents contain express references to provisions of statutes and the law of jurisdictions other than Ireland and we express no opinion on any such provision or its application to the Documents or to any Company.

Opinion
 
Subject to:
 

 (a)
the bases of opinion set out in paragraph 2 above;
 

 (b)
the assumptions and reservations set out in paragraphs 4 and 5, respectively, below; and
 

 (c)
any matters or documents not disclosed to us,
 
we are of the opinion as follows:
 
3.1
Corporate Status
 
The Parent is a public limited company having a share capital and is duly incorporated under the laws of Ireland.  It is incorporated for an indefinite period, is a separate legal entity and is subject to suit in its own name.
 
Page 4/16
Eaton Capital is a public unlimited company having a share capital and is duly incorporated under the laws of Ireland.  It is incorporated for an indefinite period, is a separate legal entity and is subject to suit in its own name.
 
Each of Cooper Industries and Eaton Domhanda are private unlimited companies having a share capital and are duly incorporated under the laws of Ireland.  They are incorporated for an indefinite period, are separate legal entities and are subject to suit in their own name.
 
The Searches do not disclose that any steps have been taken to appoint an examiner to any Company, to appoint a receiver to any Company or its assets or to wind it up.  On the basis of the Searches only, each of the Companies is validly existing.
 
3.2
Capacity and Authority of the Companies
 
Each Company has the necessary legal capacity to enter into, deliver and perform its obligations under the Documents to which it is a party and, in the case of Eaton Capital, to issue the Notes. All necessary corporate action required on the part of each Company to authorise the execution and delivery of the Documents to which it is party and, in the case of Eaton Capital, the issue of the Notes, and the performance by it of its obligations under the Documents to which it is party and, in the case of Eaton Capital, the Notes has been duly taken.
 
3.3
Due execution
 
Each Company has validly executed the Documents to which it is a party.
 
3.4
Documents: No breach of constitutional documents/laws
 
The execution and delivery by each Company of the Documents to which it is a party and, in the case of Eaton Capital, the issue of the Notes, and the performance by it of its obligations under the Documents to which it is a party and, in the case of Eaton Capital, the Notes, will not violate the Constitution of such Company or any law or regulation of general application in Ireland applicable to such Company.
 
3.5
Registrations/filings
 
No registration, filing, notarisation or recording of the Documents or the Notes is necessary under the laws of Ireland as a condition of the legality, validity, admissibility in evidence or enforceability of the Documents or the Notes in Ireland.
 
3.6
Official Authorisations
 
Based on our review of those laws and regulations which are normally applicable to transactions of the type contemplated by the Documents, the execution and delivery by each Company of the Documents to which it is a party and the performance by each Company of its obligations under the Documents to which it is a party, will not require on the part of such Company any consent, exemption, licence, approval or authorisation of any governmental or regulatory body or official of Ireland.
 
Page 5/16
3.7
Governing law
 
Council Regulation (EC) No. 593/2008 of 17 June 2008 on the law applicable to contractual obligations, as amended by Corrigendum to Regulation (EC) No 593/2008 of the European Parliament and of the Council of 17 June 2008 on the law applicable to contractual obligations (Rome I) (“Rome I”) has force of law in Ireland. The incorporation of the laws of the State of New York, as the governing law of contractual obligations arising out of the Documents is, in respect of contractual obligations which are within the scope of Rome I, valid in accordance with Article 3(1) of Rome I and accordingly, subject to and in accordance with Rome I, the laws of the State of New York will, upon proof of the relevant provisions of the relevant laws, be applied by the courts if any claim to enforce such contractual obligations against any Company party to the Documents come under their jurisdiction.
 
Council Regulation (EC) No. 864/2007 of 11 July 2007 on the law applicable to non-contractual obligations (“Rome II”) has force of law in Ireland.  The incorporation of the laws of the State of New York, as the governing law of non-contractual obligations arising out of the Documents is, in respect of non-contractual obligations which are within the scope of Rome II, valid in accordance with Article 14(1) of Rome II and accordingly, subject to and in accordance with Rome II, the laws of the State of New York will, upon proof of the relevant provisions of the relevant laws, be applied by the courts if any claim to enforce such non-contractual obligations against any Company party to the Documents comes under their jurisdiction.
 
3.8
Submission to jurisdiction
 
Any submission by a Company in the Documents to which it is a party to the jurisdiction of any New York or any federal court sitting in the Borough of Manhattan, The City of New York (together, the “New York Courts”) is legally valid, binding and enforceable against such Company under the laws of Ireland.
 
3.9
Enforcement of judgments
 
Any judgment in relation to any or all of the Documents obtained in the State of New York against a Company would be recognised and enforced in Ireland without re-trial or examination of the merits of the case provided that:
 

 (a)
the judgment has not been obtained or alleged to have been obtained by fraud or a trick;
 

 (b)
the decision of the New York court and the enforcement thereof was not and would not be contrary to natural or constitutional justice under Irish law;
 

 (c)
the enforcement of the judgment would not be contrary to public policy as understood by the courts or constitute the enforcement of a judgment of a penal or revenue nature or be inconsistent with a judgment of the courts in respect of the same matter;
 

 (d)
the judgment is final and conclusive and is for a debt or definite sum of money;
 

 (e)
the procedural rules of the New York court and the courts have been observed; and
 
Page 6/16

 (f)

Reservations and Qualifications
 
Our Opinion is subject to the following reservations and qualifications:
 
5.1
Notwithstanding any provision in the Documents to the contrary, the Documents may be capable of being amended by oral agreement or conduct of the Parties.
 
Page 12/16
5.2
Provisions in the Documents imposing additional obligations in the event of breach or default, or of payment or repayment being made other than on an agreed date, may be unenforceable to the extent that they are subsequently adjudicated to be penal in nature.  The fact that any payment is held to be penal in nature would not, of itself, prejudice the legality or validity of any other provision contained in the Documents which does not provide for the making of such payment.
 
5.3
Provisions in the Documents that calculations or certifications or acknowledgements are to be conclusive and binding will not necessarily prevent judicial enquiry by the courts into the merits of any claim by a party claiming to be aggrieved by such calculations, certifications or acknowledgements; nor do such provisions exclude the possibility of such calculations, certifications or acknowledgements being amended by order of the courts.
 
5.4
To the extent that the Documents vest a discretion in any party, or provide for any party determining any matter in its opinion, the exercise of such discretion and the manner in which such opinion is formed and the grounds on which it is based may be the subject of a judicial enquiry and review by the courts.
 
5.5
Provisions of the Documents providing for severance of provisions due to illegality, invalidity or unenforceability thereof may not be effective, depending on the nature of the illegality, invalidity or unenforceability in question.
 
5.6
The effectiveness of terms of documents exculpating a party from a liability, obligation or duty otherwise owed is limited by law.
 
5.7
The description of obligations as “enforceable” or “binding” refers to the legal character of the obligations in question.  It implies no more than that they are of a character which Irish law recognises and enforces.  It does not mean that the Documents will be binding or enforced in all circumstances or that any particular remedy will be available.  Equitable remedies, such as specific performance and injunctive relief, are at the discretion of the courts and may not be available to persons seeking to enforce provisions of the Documents.  Furthermore, the courts may not allow acceleration of amounts payable under the Documents where an event of default occurs that is considered immaterial.  More generally, in any proceedings to enforce the Documents, the courts may require that the Party seeking enforcement acts with reasonableness and good faith.  Enforcement of the Documents may also be limited as a result of (a) the provisions of Irish law applicable to contracts held to have become frustrated by events happening after their execution; and (b) any breach of the terms of the Documents by the Party seeking to enforce the same.
 
5.8
The obligations of each Party under the Documents are subject to all laws relating to insolvency, bankruptcy, liquidation, reorganisation, moratorium, examinership, trust schemes, preferential creditors, fraudulent transfer and other similar laws relating to or affecting creditors’ rights generally.
 
5.9
Where an obligation is to be performed outside Ireland under the Documents, it may not be enforceable in Ireland to the extent that performance would be illegal or contrary to public policy under the laws of that jurisdiction.
 
Page 13/16
5.10
Any judgment of the courts for moneys due under the Documents may be expressed in a currency other than euro but the order may issue out of the Central Office of the High Court expressed in euro by reference to the official rate of exchange prevailing on the date of issue.  In addition, in a winding-up in Ireland of an Irish incorporated company, all foreign currency claims must be converted into an Irish currency for the purposes of proof.  The rate of exchange to be used to convert foreign currency debts into euro for the purposes of proof in a winding-up is the spot rate as of, in the case of a compulsory winding-up, either the date of commencement of the winding-up (presentation of the petition for winding-up or earlier resolution for winding-up) or of the winding-up order and, in the case of a voluntary winding-up, on the date of the relevant winding-up resolution.
 
5.11
A court may refuse to give effect to a purported contractual obligation to pay costs arising from unsuccessful litigation brought against a party and may not award by way of costs all of the expenditure incurred by a successful litigator in proceedings before that court.
 
5.12
Claims against any Party may be or become the subject of set-off or counterclaim and any waiver of those or other defences available to each Party may not be enforceable in all circumstances.
 
5.13
Currency indemnities contained in the Documents may not be enforceable in all circumstances.
 
5.14
We express no opinion on how courts outside Ireland would apply the laws of Ireland in relation to any aspect of the Documents.
 
5.15
The courts will not decline any mandatory jurisdiction arising pursuant to Council Regulation (EC) No. 1215/2012 of 12 December 2012 on Jurisdiction and the Recognition and Enforcement of Judgments in Civil and Commercial Matters.
 
5.16
Claims against any Party may become barred under relevant statutes of limitation if not pursued within the time limited by such statutes.
 
5.17
We have not been responsible for investigating or verifying the accuracy of the facts, including statements of law, or the reasonableness of any statement of opinion contained in the Prospectus or that no material information has been omitted therefrom.
 
5.18
The failure of the Searches to reveal evidence that any Company has passed a voluntary winding-up resolution, that a petition has been presented or order made by a court for the winding-up of, or appointment of an examiner to any Company or that a receiver or similar officer has been appointed in relation to any of its assets or revenues is not conclusive proof that no such event has occurred, in particular:
 

 (a)
the Searches may not have revealed whether a petition for winding-up or the appointment of any examiner had been presented;
 

 (b)
notice of a resolution passed, a winding-up order made or the appointment of a receiver or examiner may not have been filed at the Companies Registration Office, Dublin immediately;
 

 (c)
searches have not been undertaken in any Office of the Circuit Court, notwithstanding that the Circuit Court has jurisdiction with respect to the examinership of certain companies; and
 

 (d)
the position may have changed since the time the Searches were made.

4.5
Where an assumption is stated to be made in this opinion, we have not made any investigation with respect to the matters that are the subject of such assumption and we express no views as to such matters.
 
5.
OPINION
 
Based upon and subject to the foregoing and to the further qualifications set out below and subject to any factual matters, documents or events not disclosed to us by the parties concerned, having regard to such legal considerations as we deem relevant, we are of the opinion that:
 
5.1
Corporate Status, Power and Capacity of the Company
 

 5.1.1
The Company is registered as: (a) a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid); (b) incorporated on 9 January 2008; and (c) validly existing under the laws of The Netherlands.
 

 5.1.2
The Company has:
 

 (a)
the corporate power and corporate authority to execute and deliver the Indenture and Dutch Guarantee and to undertake and to perform the obligations (and exercise its rights) expressed to be assumed by it therein; and
 

 (b)
taken all internal corporate action required by its Articles of Association and by Dutch corporate law to approve and to authorise the execution and delivery of the Dutch Guarantee and the performance of its obligations under such Dutch Guarantee.
 

 5.1.3

6.
QUALIFICATIONS
 
The opinions expressed above are subject to the following qualifications:
 
6.1
Netherlands substantive law does not have a concept or doctrine identical to the Anglo-American concept of “trust”; nevertheless any trust validly created under its governing law by the Indenture will be recognised by the courts of The Netherlands in accordance with, and subject to the limitations of, the rules of The Hague Convention on the Law Applicable to Trusts and on their Recognition;
 
6.2
in issuing this opinion we do not assume any obligation to notify or inform you of any developments subsequent to its date that might render its content untrue or inaccurate in whole or in part at such time; and

7.
RELIANCE
 
This opinion:
 

 7.1.1
expresses and describes Netherlands legal concepts in English and not in their original Dutch terms; therefore, this opinion is issued and may only be relied upon on the express condition that it shall be governed by, and that all words and expressions used herein shall be construed and interpreted in accordance with, the laws of The Netherlands;

We have not reviewed any other document than the Documents. Except as stated expressly herein, we have not examined any other agreements, arrangements, instruments or other documents affecting, directly or indirectly, either the parties to the Documents or the Documents, nor have we made any other enquiries concerning any of the parties.
 
Nothing in this legal opinion should be construed as implying that we are familiar with the affairs of any party to the Agreements or any of their affiliates and this legal opinion is based solely on the Documents. We assume no responsibility for the investigation or verification of any statements of facts or the reasonableness of any assumption or statement of opinion (including, without limitation, as to any representations and warranties and as to the solvency of any party to the Agreements), without prejudice to the opinions expressed below in this legal opinion.
 
3.
This legal opinion speaks as of its date and is confined to and is given solely on the basis of the laws of Luxembourg as presently in force. We do not purport to be experts on, or generally familiar with, any law other than the laws of Luxembourg. Accordingly, we express no opinion herein with regard to any system of law other than the laws of Luxembourg in force at the date hereof, as currently published, and as interpreted and applied in published case law of Luxembourg courts.
 
This legal opinion expresses and describes Luxembourg legal concepts in English and not in their original French or German form. Luxembourg legal concepts expressed in English are to be construed in accordance with the Luxembourg legal concepts to which they refer. It cannot be excluded that due to the differences of legal systems, some words or phrases may have different connotations than the French or German words or phrases would have.
 
Furthermore, we have not been instructed to review or opine on any matter with respect to and we express no opinion as to and, assume that the opinions herein are not affected by (i) the capacity, power or existence of any party to the Agreements (other than the Companies), (ii) the due execution of the Agreements (other than by the Companies), (iii) the legality, validity, enforceability or admissibility in evidence of the Agreements, (iv) any liability to tax, which may arise or be suffered as a result of, or in connection with, any of the Documents or their execution, creation, issue, performance or enforcement, (v) any public international law or the rules of, or promulgated under, any treaty or by any treaty organisation, except to the extent it would have any direct effect under Luxembourg law, or (vi) on the laws of any jurisdiction other than Luxembourg.
 
No opinion is given that the future or continued performance of the obligations of any of the parties to the Agreements or the consummation of the transactions contemplated in the Agreements will not contravene Luxembourg law if such law is altered after the date hereof. We assume no obligation to advise any party or person of any changes of law or fact which occur after the date of this legal opinion, even if such change may affect the legal analysis, legal conclusions or information contained in this legal opinion.
 
4.
Based upon the assumptions set out in Schedule A and subject to the qualifications set out in Schedule B, and subject to any matters not disclosed to us, we are, as at the date hereof, of the following opinion:
 
Status, power, authority and authorization
 

 (a)
Each Company has been incorporated for an unlimited duration and legally exists as a private limited liability company (société à responsabilité limitée) under the laws of Luxembourg.
 

 (b)
Each Company has the corporate power and authority to enter into the Agreements and to perform its obligations thereunder.

Due execution

No conflict
 

 (f)
Neither the entry by the Companies into the Agreements, nor the performance by any Company of its obligations thereunder, conflict with any provision of the Articles or the Luxembourg act dated 10 August 1915 on commercial companies, as amended (the “Luxembourg Companies Act”).
 
5.
We have given this legal opinion solely for the benefit of the Addressees in connection with the Registration Statement and the Agreements.

In giving such consent we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.
 
6.
Any Addressee who is entitled to, and does rely on this legal opinion agrees that, to the fullest extent permitted by law (and except in case of willful misconduct or fraud), there is no assumption of personal duty of care, and such person will not bring any personal claim against any individual who is a representative of, proxyholder of, partner of, members of, manager of, employee or consultant of, White & Case LLP, White & Case S.à r.l. or any other White & Case undertaking.
 
7.
This legal opinion is strictly limited to the matters stated herein and may not be read or construed as extending by implication to any matters not specifically referred to. The schedules to this legal opinion form an integral part of this legal opinion.

Yours sincerely,

Schedule B – Qualifications
 
Our opinion is subject to the following qualifications:
 
1.
Where any person is vested with discretion or may determine a matter in its opinion, Luxembourg law may require that such discretion is exercised in good faith.
 
2.
This legal opinion is subject to any limitations arising from bankruptcy (faillite), insolvency, liquidation, administrative dissolution without liquidation (dissolution administrative sans liquidation), reprieve from payment (sursis de paiement), judicial reorganization (réorganisation judiciaire), reorganization by amicable agreement (réorganisation par accord amiable), moratorium, reorganisation and other laws of general application relating to or affecting the rights of creditors generally, as well as any health and safety laws and regulations, any laws, regulations and policies relating to racketeering, criminal and civil forfeiture, emergencies, foreign asset or trading controls, corrupt practices, national security, terrorism or money laundering or governing foreign investment in Luxembourg.
 
3.
We express no opinion on the effectiveness or ineffectiveness of a purported revocation, or the consequences of such revocation by the principal of a power of attorney or agency (mandat) expressed to be irrevocable.
 
4.
We express no tax opinion whatsoever in respect of the Companies or the tax consequences of the transactions contemplated by the Agreements.
 
5.
We express no opinion as to whether the performance of the Agreements would cause any borrowing limits, debt/equity or other ratios possibly agreed with the tax authorities to be exceeded nor as to the consequences thereof.
 
6.
A Luxembourg company may only encumber its assets or provide guarantees in accordance with its corporate objects and for its corporate benefit. There is no Luxembourg legislation governing group companies which specifically regulates the establishment, organisation and liability of groups of companies. Consequently, the concept of group interest as opposed to the interest of the individual corporate entity is not expressly recognised. A company may, in principle, not encumber its assets or provide guarantees in favour of group companies in general (at least as far as parent companies and fellow subsidiaries of its parent companies are concerned).
 
Based on relevant French and Belgian case law and legal literature (to which Luxembourg courts are likely to refer in this context), we would take the view that a Luxembourg company may, in principle, validly assist other group companies if:
 

 (a)
they are part of an integrated group;
 

 (b)
it can be established that the company derives a benefit from granting such assistance or that at least, there is no disruption of the balance of interests in the group to the detriment of the Luxembourg company; and
 

 (c)
the assistance is not in terms of the amounts involved disproportionate to the company’s financial means and the benefits derived from granting such assistance.
 
7.
If the assistance is deemed contrary to the interest of the company by the courts, its directors may be held liable for action taken in that context. Further, under certain circumstances, the directors of the Luxembourg company might incur criminal penalties based on the concept of misappropriation of corporate assets (article 1500-11 of the Luxembourg act dated 10 August 1915 on commercial companies, as amended (the “Luxembourg Companies Act”)). Article 1500-11 of the Luxembourg Companies Act makes it a criminal offence for the directors and managers of a Luxembourg company, whether having been officially appointed or being de facto directors or managers (which concept might include legal persons), if, acting in bad faith, they have made use of corporate assets or of corporate credit for uses other than those required by the interests of such company and for their own personal benefit or for the benefit of companies or enterprises in which they have a direct or indirect interest. It cannot be excluded ultimately that, if the relevant transaction were to be considered as a misappropriation of corporate assets by a Luxembourg court or if it could be evidenced that the other parties to the transaction were aware of the fact that the transaction was not for the corporate benefit of the Luxembourg company, the transaction might be declared void or ineffective based on the concept of illegal cause (cause illicite). Also, depending on the factual circumstances, a liquidator, an insolvency receiver or creditors of the assisting company could seek the liability of the banks (e.g., where the guarantee trigger has caused the insolvency of the assisting company and/or has caused a wider consequential loss to the creditors of such company).
 
8.
We express no opinion whatsoever on regulatory matters or matters of fact or on matters other than those expressly set forth in this legal opinion, and no opinion is, or may be, implied or inferred herefrom.
 
9.
The rights and obligations of the parties under the Agreements may be limited by the effects of criminal measures, including without limitation criminal freezing orders, public law sanctions or restraining measures taken from time to time under applicable laws treaties or other instruments.
 
10.
Any national or international economic sanctions or other similar measures that may be applicable, directly or indirectly, to any party to the Documents, may result in the obligations of that party or other parties to the Documents being unenforceable or void or otherwise affected.
 
11.
A search at the Insolvency Register is not capable of conclusively revealing whether a (and the Negative Certificates do not constitute conclusive evidence that no) winding-up resolution or petition, or an order adjudicating or declaring a, or a petition or filing for, bankruptcy (faillite) or reprieve from payment (sursis de paiement), judicial reorganization (réorganisation judiciaire), judicial liquidation (liquidation judiciaire), administrative dissolution without liquidation (dissolution administrative sans liquidation) or similar action has been adopted or made.
 
12.
By application of article 1200-1 of the Luxembourg Companies Act, a company not respecting any provision of Luxembourg criminal law or which seriously contravenes any provision of the Luxembourg commercial code or any other Luxembourg law applicable to commercial companies may be put into judicial dissolution and liquidation upon the application of the public prosecutor
 
13.
The corporate documents of, and relevant court orders affecting, a Luxembourg company (including, but not limited to, the notice of a winding-up order or resolution, notice of the appointment of a receiver or similar officer) may not be held at the Register immediately and there is generally a delay in the relevant document appearing on the files regarding the company concerned. Furthermore, it cannot be ruled out that the required filing of documents has not occurred or that documents filed with the Register may have been mislaid or lost. In accordance with Luxembourg company law, changes or amendments to corporate documents to be filed at the Register will be effective (opposable) vis-à-vis third parties only as of the day of their publication in the Official Gazette unless the company proves that the relevant third parties had prior knowledge thereof.
 
14.
We express no tax opinion whatsoever in respect of the Companies or the tax consequences of the transactions contemplated by the Agreements.
 
15.
Actions in Luxembourg courts must, in principle, be brought in the name of the principal not in the name of an agent of the principal
 
16.
The Luxembourg Companies Act reserves the right and the power to decide on certain matters (such as the winding-up or the liquidation of a company, the merger, the increase of the share capital, the distribution of dividends or the amendment of the articles of incorporation of the company) exclusively to the shareholders of the company.
 
17.
A receiver may be limited in the exercise of its rights and powers (i) pursuant to the Luxembourg Companies Act and (ii), in the case of insolvency of a Luxembourg company, by the rights and powers of the insolvency receiver appointed by a Luxembourg court pursuant to Luxembourg insolvency laws. Further, the rights and powers of a receiver may not cover or extend to actions which, pursuant to the Luxembourg Companies Act or the Articles, require a decision of the shareholders of a Luxembourg company rather than the Luxembourg company itself.
 
18.
We express no opinion on the legal validity and the enforceability of the Agreements or any obligation thereof.

Schedule B – Qualifications
 
Our opinion is subject to the following qualifications:
 
1.
Where any person is vested with discretion or may determine a matter in its opinion, Luxembourg law may require that such discretion is exercised in good faith.
 
2.
This legal opinion is subject to any limitations arising from bankruptcy (faillite), insolvency, liquidation, administrative dissolution without liquidation (dissolution administrative sans liquidation), reprieve from payment (sursis de paiement), judicial reorganization (réorganisation judiciaire), reorganization by amicable agreement (réorganisation par accord amiable), moratorium, reorganisation and other laws of general application relating to or affecting the rights of creditors generally, as well as any health and safety laws and regulations, any laws, regulations and policies relating to racketeering, criminal and civil forfeiture, emergencies, foreign asset or trading controls, corrupt practices, national security, terrorism or money laundering or governing foreign investment in Luxembourg.
 
3.
We express no opinion on the effectiveness or ineffectiveness of a purported revocation, or the consequences of such revocation by the principal of a power of attorney or agency (mandat) expressed to be irrevocable.
 
4.
We express no tax opinion whatsoever in respect of the Companies or the tax consequences of the transactions contemplated by the Agreements.
 
5.
We express no opinion as to whether the performance of the Agreements would cause any borrowing limits, debt/equity or other ratios possibly agreed with the tax authorities to be exceeded nor as to the consequences thereof.
 
6.
A Luxembourg company may only encumber its assets or provide guarantees in accordance with its corporate objects and for its corporate benefit. There is no Luxembourg legislation governing group companies which specifically regulates the establishment, organisation and liability of groups of companies. Consequently, the concept of group interest as opposed to the interest of the individual corporate entity is not expressly recognised. A company may, in principle, not encumber its assets or provide guarantees in favour of group companies in general (at least as far as parent companies and fellow subsidiaries of its parent companies are concerned).
 
Based on relevant French and Belgian case law and legal literature (to which Luxembourg courts are likely to refer in this context), we would take the view that a Luxembourg company may, in principle, validly assist other group companies if:


 (a)
they are part of an integrated group;
 

 (b)
it can be established that the company derives a benefit from granting such assistance or that at least, there is no disruption of the balance of interests in the group to the detriment of the Luxembourg company; and
 

 (c)
the assistance is not in terms of the amounts involved disproportionate to the company’s financial means and the benefits derived from granting such assistance.
 
7.
If the assistance is deemed contrary to the interest of the company by the courts, its directors may be held liable for action taken in that context. Further, under certain circumstances, the directors of the Luxembourg company might incur criminal penalties based on the concept of misappropriation of corporate assets (article 1500-11 of the Luxembourg act dated 10 August 1915 on commercial companies, as amended (the “Luxembourg Companies Act”)). Article 1500-11 of the Luxembourg Companies Act makes it a criminal offence for the directors and managers of a Luxembourg company, whether having been officially appointed or being de facto directors or managers (which concept might include legal persons), if, acting in bad faith, they have made use of corporate assets or of corporate credit for uses other than those required by the interests of such company and for their own personal benefit or for the benefit of companies or enterprises in which they have a direct or indirect interest. It cannot be excluded ultimately that, if the relevant transaction were to be considered as a misappropriation of corporate assets by a Luxembourg court or if it could be evidenced that the other parties to the transaction were aware of the fact that the transaction was not for the corporate benefit of the Luxembourg company, the transaction might be declared void or ineffective based on the concept of illegal cause (cause illicite). Also, depending on the factual circumstances, a liquidator, an insolvency receiver or creditors of the assisting company could seek the liability of the banks (e.g., where the guarantee trigger has caused the insolvency of the assisting company and/or has caused a wider consequential loss to the creditors of such company).
 
8.
We express no opinion whatsoever on regulatory matters or matters of fact or on matters other than those expressly set forth in this legal opinion, and no opinion is, or may be, implied or inferred herefrom.
 
9.
The rights and obligations of the parties under the Agreements may be limited by the effects of criminal measures, including without limitation criminal freezing orders, public law sanctions or restraining measures taken from time to time under applicable laws treaties or other instruments.
 
10.
Any national or international economic sanctions or other similar measures that may be applicable, directly or indirectly, to any party to the Documents, may result in the obligations of that party or other parties to the Documents being unenforceable or void or otherwise affected.
 
11.
A search at the Insolvency Register is not capable of conclusively revealing whether a (and the Negative Certificates do not constitute conclusive evidence that no) winding-up resolution or petition, or an order adjudicating or declaring a, or a petition or filing for, bankruptcy (faillite) or reprieve from payment (sursis de paiement), judicial reorganization (réorganisation judiciaire), judicial liquidation (liquidation judiciaire), administrative dissolution without liquidation (dissolution administrative sans liquidation) or similar action has been adopted or made.
 
12.
By application of article 1200-1 of the Luxembourg Companies Act, a company not respecting any provision of Luxembourg criminal law or which seriously contravenes any provision of the Luxembourg commercial code or any other Luxembourg law applicable to commercial companies may be put into judicial dissolution and liquidation upon the application of the public prosecutor
 
13.
The corporate documents of, and relevant court orders affecting, a Luxembourg company (including, but not limited to, the notice of a winding-up order or resolution, notice of the appointment of a receiver or similar officer) may not be held at the Register immediately and there is generally a delay in the relevant document appearing on the files regarding the company concerned. Furthermore, it cannot be ruled out that the required filing of documents has not occurred or that documents filed with the Register may have been mislaid or lost. In accordance with Luxembourg company law, changes or amendments to corporate documents to be filed at the Register will be effective (opposable) vis-à-vis third parties only as of the day of their publication in the Official Gazette unless the company proves that the relevant third parties had prior knowledge thereof.
 
14.
We express no tax opinion whatsoever in respect of the Companies or the tax consequences of the transactions contemplated by the Agreements.
 
15.
Actions in Luxembourg courts must, in principle, be brought in the name of the principal not in the name of an agent of the principal
 
16.
The Luxembourg Companies Act reserves the right and the power to decide on certain matters (such as the winding-up or the liquidation of a company, the merger, the increase of the share capital, the distribution of dividends or the amendment of the articles of incorporation of the company) exclusively to the shareholders of the company.
 
17.
A receiver may be limited in the exercise of its rights and powers (i) pursuant to the Luxembourg Companies Act and (ii), in the case of insolvency of a Luxembourg company, by the rights and powers of the insolvency receiver appointed by a Luxembourg court pursuant to Luxembourg insolvency laws. Further, the rights and powers of a receiver may not cover or extend to actions which, pursuant to the Luxembourg Companies Act or the Articles, require a decision of the shareholders of a Luxembourg company rather than the Luxembourg company itself.
 
18.
We express no opinion on the legal validity and the enforceability of the Agreements or any obligation thereof.

The Notes are being issued pursuant to an indenture, dated as of May 9, 2025 (the “Base Indenture”), among the Issuer, the Covered Guarantors and each of the entities listed on Part C of Schedule I hereto (the “Non-Covered Guarantors” and, together with the Covered Guarantors, the “Guarantors”) and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the third supplemental indenture, dated as of the date hereof, among the Issuer, the Guarantors and the Trustee (the Base Indenture, as so supplemented, the “Indenture”). In connection with the issuance and sale of the Notes, the Issuer, the Guarantors and Barclays Capital Inc., BofA Securities, Inc., Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, as representatives of the several underwriters (collectively, the “Underwriters”), entered into an Underwriting Agreement, dated March 4, 2026 (the “Underwriting Agreement”), attached to the Terms Agreement dated March 4, 2026 (together with the Underwriting Agreement, the “Terms Agreement”).
 
This opinion letter is rendered in accordance with the requirements of Item 601(b)(5) of Regulation S–K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related prospectus, any prospectus filed pursuant to Rule 424(b) with respect thereto, other than as expressly stated herein with respect to the issuance and sale of the Notes.
 
In connection with our opinions expressed below, we have examined originals or copies certified or otherwise identified to our satisfaction of the following documents and such other documents, corporate records, certificates and other statements of government officials and corporate officers of the Issuer and Guarantors, as applicable, as we deemed necessary for the purposes of the opinions set forth in this opinion letter:
 
March 6, 2026

We have relied, to the extent we deem such reliance proper, upon such certificates or comparable documents of officers and representatives of the Issuer and the Guarantors, as applicable, and of public officials and upon statements and information furnished by officers and representatives of the Issuer and the Guarantors with respect to the accuracy of material factual matters contained therein which were not independently established by us.
