Ladies and Gentlemen:

T-Mobile USA, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), €1,000,000,000 aggregate principal amount of its 3.150% Senior Notes due 2032 (the “2032 Notes”), €1,000,000,000 aggregate principal amount of its 3.500% Senior Notes due 2037 (the “2037 Notes”) and €750,000,000 aggregate principal amount of its 3.800% Senior Notes due 2045 (the “2045 Notes” and, together with the 2032 Notes and the 2037 Notes, the “Notes” and, together with the Guarantees (as defined below), the “Securities”). The Securities will be issued under that certain Indenture, dated as of September 15, 2022 (the “Base Indenture”), by and among the Company, T-Mobile US, Inc., a Delaware corporation (“Parent”) and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), and (a) a supplemental indenture with respect to the 2032 Notes to be dated as of the Closing Date (as defined below) (the “2032 Supplemental Indenture”), (b) a supplemental indenture with respect to the 2037 Notes to be dated as of the Closing Date (the “2037 Supplemental Indenture”) and (c) a supplemental indenture with respect to the 2045 Notes to be dated as of the Closing Date (the “2045 Supplemental Indenture” and, together with the 2032 Supplemental Indenture and the 2037 Supplemental Indenture, the “Supplemental Indentures” and each a “Supplemental Indenture”), in each case, by and among the Company, Parent, the Guarantors (as defined below) and the Trustee, including in its capacities as trustee, paying agent and registrar. The Base Indenture as amended and supplemented by each Supplemental Indenture is referred to herein as the “Indenture.”

At or prior to 6:55 P.M., London time, on the date hereof (the “Time of Sale”), the following information was prepared (collectively, the “Time of Sale Information”): the Preliminary Prospectus (as defined below) and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act (as defined below)) listed on Annex A hereto as constituting part of the Time of Sale Information.

The payment of principal of, and premium and interest on, the Notes will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally, by (i) Parent, (ii) each of the Company’s subsidiaries listed on Schedule 2 hereto and (iii) any subsidiary of the Company or Parent formed or acquired after the Closing Date that executes an additional guarantee in accordance with the terms of the Indenture, and respective successors and assigns of Parent and the subsidiaries of the Company or Parent referred to in clauses (ii) and (iii) above (collectively, the “Guarantors”), pursuant to their guarantees (the “Guarantees”).

As used in this underwriting agreement (this “Agreement”), the term “Transactions” means, collectively, (i) the issuance and sale of the Securities and (ii) the payment of all fees and expenses related to the foregoing. The term “Transaction Documents” collectively refers to this Agreement, the Base Indenture, each Supplemental Indenture and the Securities.

Each of the Company and the Guarantors hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-271553), including a prospectus, relating to the Securities. Such registration statement, as amended at the time it, and any post-effective amendment thereto, became effective, including the information, if any, deemed pursuant to Rule 430A or 430B under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means the prospectus included in the Registration Statement (the “Base Prospectus”) plus the preliminary prospectus supplement, dated February 4, 2025, to the Base Prospectus relating to the Securities at the time it was filed that omits Rule 430 Information, and the term “Prospectus” means the Base Prospectus plus the final prospectus supplement that includes the Rule 430 Information in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

2. Purchase of the Securities by the Underwriters.

(a) The Company, on the basis of the representations, warranties and agreements herein contained and subject to the terms and conditions herein set forth, agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company (x) the aggregate principal amount of 2032 Notes set forth opposite such Underwriter’s name on Schedule 1 hereto at a price equal to 99.706% of the principal amount thereof, plus accrued interest, if any, from February 11, 2025 to but excluding the Closing Date, (y) the aggregate principal amount of 2037 Notes set forth opposite such Underwriter’s name on Schedule 1 hereto at a price equal to 99.456% of the principal amount thereof, plus accrued interest, if any, from February 11, 2025 to but excluding the Closing Date and (z) the aggregate principal amount of 2045 Notes set forth opposite such Underwriter’s name on Schedule 1 hereto at a price equal to 99.260% of the principal amount thereof, plus accrued interest, if any, from February 11, 2025 to but excluding the Closing Date. The Company will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

(b) The Company understands that the Underwriters intend to make a public offering of the Securities on the terms set forth in the Prospectus. The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter; provided that (i) such offers and sales are made on the basis of the representations, warranties and agreements of the Underwriters and otherwise in accordance with the provisions of this Agreement as if such affiliates were named as Underwriters hereunder and (ii) such Underwriter shall be responsible for any actions of its affiliates.

-3-

(c) Payment for and delivery of the Securities will be made at the offices of Cahill Gordon & Reindel LLP, 32 Old Slip, New York, New York 10005, at 10:00 A.M., London time, on February 11, 2025, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing. The time and date of such payment and delivery is referred to herein as the “Closing Date.”

(d) Payment for the Securities shall be made by wire transfer in immediately available funds to the account(s) specified by the Company to the Representatives against delivery, for the respective accounts of the several Underwriters, of one or more global notes representing the Securities (collectively, the “Global Notes”), with any transfer taxes payable in connection with the sale of the Securities duly paid by the Company. Delivery of the Securities shall be made through a common depositary using the facilities of Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”), unless the Representatives shall otherwise instruct.

(e) The Company and the Guarantors acknowledge and agree that the Underwriters are acting solely in the capacity of arm’s-length contractual counterparties to the Company and the Guarantors with respect to the offering of Securities contemplated hereby (the “Offering”) (including in connection with determining the terms of the Offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Guarantors or any other person. Additionally, no Underwriter is advising the Company, the Guarantors or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction pursuant to this Agreement. The Company and the Guarantors shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the Transactions, and no Underwriter shall have any responsibility or liability to the Company or the Guarantors with respect thereto. Any review by the Underwriters of the Company, the Guarantors, the Transactions or other matters relating to such Transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company or the Guarantors.

(f) On behalf of the Underwriters, Citigroup Global Markets Limited, or such other Underwriter as the Underwriters may agree (in such capacity the “Settlement Bank”) shall coordinate with the Company to ensure settlement of the Securities on the Closing Date. The Settlement Bank acknowledges that the Global Notes will initially be credited to an account (the “Commissionaire Account”) for the benefit of the Settlement Bank, the terms of which include a third-party beneficiary clause (‘stipulation pour autrui’), with the Company as the third-party beneficiary, and which provide that such Securities are to be delivered to others only against payment of the net subscription monies for the Securities (i.e. less the commissions and expenses to be deducted from the subscription monies) into the Commissionaire Account on a delivery against payment basis.

-4-

(g) The Settlement Bank acknowledges that (i) the Global Notes shall be held to the order of the Company, as set out above and (ii) the net subscription monies for the Securities (i.e. less the commissions and expenses to be deducted from the subscription monies) received in the Commissionaire Account will be held on behalf of the Company until such time as they are transferred to the Company’s order. The Settlement Bank undertakes that the net subscription monies for the Securities (i.e. less the commissions and expenses to be deducted from the subscription monies) in the Commissionaire Account will be transferred to the Company’s order promptly following receipt of such monies in the Commissionaire Account. The Company acknowledges and accepts the benefit of the third-party beneficiary clause (‘stipulation pour autrui’) pursuant to the Belgian Civil Code, in the case of Euroclear, and the Luxembourg Civil Code, in the case of Clearstream, in each case in respect of the Commissionaire Account.

3. Representations and Warranties of the Company and the Guarantors. The Company and each of the Guarantors jointly and severally represents and warrants to each Underwriter as of the date hereof and at the Closing Date (or such other date as is expressly stated herein) that:

-13-

Prospectus, or as would not reasonably be expected to have a Material Adverse Effect, there is no pending or, to the Company’s and the Guarantors’ knowledge, threatened, action, suit, proceeding or claim by others (i) challenging the rights in or to any Intellectual Property of Parent or any Subsidiary or (ii) that Parent or any Subsidiary infringes or otherwise violates any patent, trademark, copyright, trade secret or other proprietary rights of others.

(y) Taxes. (i) Parent and each Subsidiary has accurately prepared and timely filed all federal, state, foreign and other tax returns that are required to be filed by it and has paid or made provision (to the extent required by United States generally accepted accounting principles (“U.S. GAAP”) or the applicable requirements of any non-U.S. accounting standards) for the payment of all federal, state, foreign and other tax assessments, governmental or other similar charges, including, without limitation, all sales and use taxes and taxes which Parent or any Subsidiary is obligated to withhold from amounts owing to employees, creditors and third parties, with respect to the periods covered by such tax returns (whether or not such amounts are shown as due on any tax return); (ii) no deficiency, assessment or other claim with respect to a proposed adjustment of Parent or any Subsidiary’s federal, state, local or foreign taxes is pending or, to the Company’s and the Guarantors’ knowledge, threatened; (iii) the accruals and reserves on the books and records of Parent and the Subsidiaries in respect of tax liabilities for any taxable period not finally determined are adequate (in accordance with U.S. GAAP or the applicable requirements of any non-U.S. accounting standards) to meet any assessments and related liabilities for any such period and, since December 31, 2024, Parent and the Subsidiaries have not incurred any liability for taxes other than in the ordinary course of its business; and (iv) there is no tax lien, whether imposed by any federal, state, foreign or other taxing authority, outstanding against the assets, properties or business of Parent or any Subsidiary, except, in each case of clauses (i) through (iv), as would not reasonably be expected (individually or in the aggregate) to have a Material Adverse Effect.

(z) Accounting Controls. Parent and the Subsidiaries maintain systems of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that comply with the requirements of the Exchange Act, have been designed by, or under the supervision of, their respective principal executive and principal financial officers, or persons performing similar functions, are effective and have been designed to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with U.S. GAAP (or the applicable requirements of any non-U.S. accounting standards) and to maintain accountability for assets, (iii) access to material assets is permitted only in accordance with management’s general or specific authorization, (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences, and (v) the interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus fairly present the information called for in all material respects and are prepared in accordance with the Commission’s rules and guidelines applicable thereto.

-14-

existing material weaknesses in their internal control over financial reporting. Since the date of the latest audited financial statements included or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus, there has been no change in Parent’s internal control over financial reporting that has materially affected, or is reasonably likely to materially adversely affect, Parent’s internal control over financial reporting.

(aa) Disclosure Controls. Parent maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) that have been designed to ensure that material information relating to Parent and its subsidiaries is disclosed to Parent’s principal executive officer and principal financial officer by others within those entities and, as of December 31, 2024, such disclosure controls and procedures were effective.

(bb) Property and Casualty Insurance. Parent and the Subsidiaries maintain property and casualty insurance in such amounts and covering such risks as Parent and the Subsidiaries reasonably consider adequate for the conduct of Parent’s and each Subsidiary’s businesses and the value of Parent’s and each Subsidiary’s properties and as is customary for publicly held companies engaged in similar businesses in similar industries, all of which property and casualty insurance is in full force and effect, except where the failure to maintain such property and casualty insurance would not reasonably be expected to have a Material Adverse Effect. There are no material claims by Parent or any Subsidiary under any such insurance policy or instrument as to which any insurance company is denying liability or defending under a reservation of rights clause. Parent has no reason to believe that Parent and each Subsidiary will not be able to renew their respective existing property and casualty insurance as and when such coverage expires or will be able to obtain replacement property and casualty insurance adequate for the conduct of the business and the value of its properties at a cost that would not reasonably be expected to have a Material Adverse Effect. Neither Parent nor any Subsidiary has received notice from any insurer or agent of such insurer that substantial capital improvements or other expenditures will have to be made in order to continue such property and casualty insurance.

(cc) No Undisclosed Relationships. Except as disclosed in the Registration Statement, the Time of Sale Information and the Prospectus, no relationship material to Parent and the Subsidiaries taken as a whole, direct or indirect, exists between or among Parent, any Subsidiary or, to the Company’s and the Guarantors’ knowledge, any affiliate of the Company, on the one hand, and any director, executive officer or, to the Company’s and the Guarantors’ knowledge, security holder (or any immediate family member of such director, executive officer or security holder), of Parent, any Subsidiary or any affiliate of the Company, on the other hand, which is required by the Securities Act to be described in the Registration Statement, the Time of Sale Information and the Prospectus and that is not so described. There are no material outstanding loans, advances (except normal advances for business expenses in the ordinary course of business) or guarantees of indebtedness by the Company or Parent to or for the benefit of any of the executive officers or directors of the Company or Parent or any of their respective family members. Parent has not, in violation of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes-Oxley Act”), directly or indirectly, including through a Subsidiary, extended or maintained credit, arranged for the extension of credit, or renewed an extension of credit, in the form of a personal loan to or for any director or executive officer of Parent.

(ee) No Stabilization or Manipulation. None of Parent, any Subsidiary, or any controlled affiliate (within the meaning of Rule 144 under the Securities Act) of the Company has (i) taken, directly or indirectly, any action which constitutes or is designed to cause or result in, or which would reasonably be expected to constitute, cause or result in, the stabilization or manipulation of the price of any security of Parent or any Subsidiary to facilitate the sale or distribution of the Securities or (ii) since the date of the Preliminary Prospectus (A) sold, bid for, purchased or paid any person any compensation for soliciting purchases of the Securities or (B) paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of Parent or any Subsidiary.

If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representatives may designate, such amendments or supplements to the Prospectus (or any document to be filed with the Commission and incorporated by reference) as may be necessary so that the statements in the Prospectus as so amended or supplemented (including such documents to be incorporated by reference therein) will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law.

The Company will, with cooperation from the Representatives and the counsel for the Underwriters, qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will continue such qualifications in effect so long as required for the offering and sale of the Securities but in no event longer than 180 days from the Closing Date; provided that neither the Company nor any of the Guarantors shall be

-22-

required to (i) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction where it would not otherwise be required to so qualify, (ii) execute or file any general consent to service of process in any such jurisdiction or take any other action that would subject itself to general service of process in such jurisdiction or (iii) subject itself to taxation in any such jurisdiction if it is not otherwise so subject.

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus” (as defined in Rule 405 under the Securities Act) (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement and any press release issued by the Company) other than (i) a free writing prospectus that, solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 under the Securities Act, (ii) any Issuer Free Writing Prospectus listed on Annex A or

7. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Company and each of the Guarantors agree, jointly and severally, to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable and actual out-of-pocket legal fees and other reasonable and actual out-of-pocket expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or

-26-

supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to an Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

(b) Indemnification of the Company and the Guarantors. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless (i) each of the Company and the Guarantors, (ii) each of their respective directors and officers who signed the Registration Statement and (iii) each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following: the first sentence of the fourth paragraph, the fifth sentence of the sixth paragraph and the ninth paragraph in the section entitled “Underwriting” in the Prospectus.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraphs (a) and (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person other than under paragraphs (a) and (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person (which consent shall not be unreasonably withheld, conditioned or delayed) be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that

-27-

there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case in these clauses (i) through (iv), the Indemnifying Person’s obligations shall be for reasonable and actual outside counsel fees and expenses. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company and the Guarantors, each of their respective directors, each of their respective officers who signed the Registration Statement and any control persons of the foregoing shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, as applicable, on the one hand and the Underwriters on the other from the Offering and also to reflect the relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, as applicable, on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company and the Guarantors from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors, as applicable, on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

-28-

(e) Limitation on Liability. The Company, the Guarantors, and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall any Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the Offering exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligation hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery of a counterpart hereof by each of the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by written notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by Parent or any Subsidiaries shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal, New York State or European Union authorities; (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the reasonable judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the Offering; or (v) other than as set forth in the Registration Statement, the Time of Sale Information and the Prospectus, the occurrence of any change in the financial condition, business, properties, assets, prospects or results of operations of Parent and its subsidiaries, taken as a whole, that, in the reasonable judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

-29-

10. Default by One or More of the Underwriters.

(a) If one or more of the Underwriters shall fail at the Closing Date to purchase any of the 2032 Notes, the 2037 Notes and/or the 2045 Notes which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), then the non-defaulting Underwriters shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other Underwriters, to purchase all, but not less than all, of such Defaulted Notes, as the case may be, in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the non-defaulting Underwriters shall not have completed such arrangements within such 24-hour period, then:

(i) if the aggregate principal amount of Defaulted Notes does not exceed 10% of the respective aggregate principal amounts of the 2032 Notes, the 2037 Notes and/or the 2045 Notes, as the case may be, to be purchased on such date pursuant to this Agreement, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations under this Agreement bear to the purchase obligations of all non-defaulting Underwriters of such 2032 Notes, the 2037 Notes and/or the 2045 Notes, as the case may be; or

(ii) if the aggregate principal amount of Defaulted Notes exceeds 10% of the respective aggregate principal amounts of the 2032 Notes, the 2037 Notes and/or the 2045 Notes, as the case may be, to be purchased on such date pursuant to this Agreement, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

(b) No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement, the non-defaulting Underwriters and the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Prospectus or in any other documents or arrangement.

11. Payment of Expenses.

(a) Whether or not the Transactions are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all reasonable costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and Deloitte; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives may designate and the preparation, printing and distribution of a Blue Sky

The Company shall not be obligated to pay any expenses incurred in connection with any “road show” presentation to potential investors (including investor meetings, ground transportation, conference calls, NetRoadshow and document processing). Neither the Company nor any Guarantor shall be obligated in any manner to pay or reimburse any expenses or other costs of any of the Underwriters, other than as set forth in clauses (v), (viii) and (ix) of this paragraph, paragraph (b) of this Section and pursuant to Section 7, including, but not limited to, the costs and expenses of the Underwriters’ legal counsel or any costs incurred by the Underwriters.

(b) If (i) this Agreement is terminated pursuant to Section 9 (other than clauses (i), (iii) and (iv) of Section 9), (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Underwriters for all reasonable and actual out-of-pocket costs and expenses (including the fees and expenses of its outside counsel) reasonably incurred by the Underwriters in connection with this Agreement and the Offering.

(c) Each Underwriter agrees to pay the portion of any expenses payable by the Underwriters represented by such Underwriter’s pro rata share (based on the proportion that the principal amount of Securities set forth opposite each Underwriter’s name in Schedule 1 bears to the aggregate principal amount of Securities set forth opposite the names of all Underwriters) of the Securities (with respect to each Underwriter, the “Pro Rata Expenses”). Notwithstanding anything contained in the International Capital Market Association Primary Market Handbook, each Underwriter hereby agrees that the Settlement Lead Manager (as defined below) may allocate the Pro Rata Expenses to the account of such Underwriter for settlement of accounts (including payment of such Underwriter’s fees by the Settlement Lead Manager) as soon as practicable but in any case no later than 90 days following the Closing Date.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of any Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from an Underwriter shall be deemed to be a successor merely by reason of such purchase.

-31-

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements, as applicable, of the Company, the Guarantors and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company, the Guarantors or the Underwriters. The respective representations, agreements, covenants, indemnities and other statements set forth in Sections 7 and 11 shall survive the termination of this Agreement, regardless of any termination or cancellation of this Agreement.

Exhibit A-6

[Form of Reverse Side of Initial Note]

3.150% Senior Notes due 2032 (the “Notes”)

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST.

Interest shall be computed on the basis of (i) the actual number of days in the period for which interest is being calculated and (ii) the actual number of days from and including the last date on which interest was paid on the Notes (or from and including February 11, 2025, if no interest has been paid on the Notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The amount of interest payable for any period shorter than a full monthly period shall be computed on the basis of the actual number of calendar days elapsed in such a period. Interest shall accrue on the principal amount of this Note from and including February 11, 2025 until maturity at a rate per annum equal to 3.150%.

The Issuer promises to pay interest annually in arrears on February 11 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that the first Interest Payment Date shall be February 11, 2026. If an interest payment date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next succeeding Business Day as if made on the date the payment was due, and no interest shall accrue for the intervening period.

(2) METHOD OF PAYMENT.

The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the Business Day immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.14 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Issuer maintained for such purpose in London, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the books and records of the Registrar; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent.

All payments of interest and principal, including payments made upon any redemption of the Notes, will be payable in euros. If, on or after February 4, 2025, the euro is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the Issuer’s control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions

Exhibit A-7

by public institutions of or within the international banking community, then all payments in respect of the Notes and the related Note Guarantees as required pursuant to the Indenture will be made in U.S. dollars until the euro is again available to the Issuer or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recently available market exchange rate for euros, as determined in the Issuer’s sole discretion. Any payment in respect of the Notes so made in U.S. dollars will not constitute an Event of Default under the Notes or the Indenture.

[The Holder of a Definitive Note is not required to surrender such Definitive Note to the Trustee in order to receive payment of principal at maturity. Such Definitive Note, after payment has been made, shall be cancelled without the requirement of presentation.]³

(3) PAYING AGENT AND REGISTRAR.

Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

(4) INDENTURE.

The Issuer issued the Notes pursuant to an Indenture dated as of September 15, 2022 (the “Base Indenture”) among the Issuer, Parent and the Trustee, as amended and supplemented with respect to the Notes by the Twenty-Second Supplemental Indenture dated as of February 11, 2025 (the “Twenty-Second Supplemental Indenture”; the Base Indenture, as amended and supplemented with respect to the Notes by the Twenty-Second Supplemental Indenture, the “Indenture”).

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and to the Trust Indenture Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are senior unsecured, unsubordinated obligations of the Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

The Issuer’s obligations under the Notes are unconditionally guaranteed on a senior unsecured basis, to the extent set forth in the Indenture, by each of the Guarantors to the extent set forth in the Indenture.

Exhibit A-8

(5) OPTIONAL REDEMPTION.

Prior to November 11, 2031 (the “Par Call Date”), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by the Issuer, a German government bond whose maturity is closest to the applicable Par Call Date of the Notes to be redeemed, or if such independent investment bank in its discretion determines that such similar bond is not in issue, such other German government bond as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Issuer, determine to be appropriate for determining the Comparable Government Bond Rate.

“Comparable Government Bond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the Comparable Government Bond on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment bank selected by the Issuer.

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

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

The Trustee shall have no responsibility for calculating the redemption price for the Notes.

Exhibit A-9

Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. At or before 10:00 a.m. (London time) on the redemption date, the Issuer will deposit with the paying agent money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. If less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected in accordance with the procedures of Euroclear Bank SA/NV and Clearstream Banking, société anonyme, as applicable.

For the avoidance of doubt, the requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

(6) TAX REDEMPTION.

The Notes may be redeemed at the Issuer’s option, in whole but not in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, together with interest accrued and unpaid to the date fixed for redemption, at any time, on giving not less than 10 nor more than 60 days’ notice in accordance with “Notice of Redemption” below if:

(a) the Issuer has or will become obligated to pay Additional Amounts as a result of any change in or amendment to the laws, regulations or rulings of the United States or any political subdivision or any taxing authority of or in the United States affecting taxation, or any change in or amendment to an official application, or interpretation of such laws, regulations or rulings (including by virtue of a holding of a court of competent jurisdiction), which change or amendment is announced and becomes effective on or after February 4, 2025, or

(b) any action shall have been taken by a taxing authority, or any decision has been rendered by a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any such actions specified in (a) above, whether or not such action was taken or brought, or such decision was rendered, with respect to the Issuer, in any such case on or after February 4, 2025, which action or decision results in a substantial likelihood that the Issuer will be required to pay Additional Amounts on the next interest payment date.

However, no such notice of redemption shall be given (1) earlier than 90 days prior to the earliest date on which the Issuer would be, in the case of a redemption for the reasons specified in (a) above, or on which there would be a substantial likelihood that the Issuer would be, in the case of a redemption for the reasons specified in (b) above, obligated to pay such Additional Amounts if a payment in respect of the Notes were then due and (2) unless, at the time such notification of redemption is given, such circumstances remain in effect.

Exhibit A-10

Prior to the publication of any notice of redemption pursuant to this section, the Issuer will deliver to the Trustee:

(1) a certificate signed by one of the Issuer’s duly authorized officers stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the Issuer’s right to redeem have occurred, and

(2) in the case of a redemption for the reasons specified in (a) or (b) above, a written opinion of independent legal counsel of recognized standing to the effect that the Issuer has or will become obligated to pay such Additional Amounts as a result of such change or amendment or that there is a substantial likelihood that the Issuer will be required to pay such Additional Amounts as a result of such action or decision, as the case may be.

Such notice, once delivered by the Issuer to the Trustee, will be irrevocable.

(7) MANDATORY REDEMPTION.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

(8) NOTICE OF REDEMPTION.

Notice of redemption will be sent at least 10 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed, except that redemption notices may be sent or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than €100,000 may be redeemed in part but only in whole multiples of €1,000, unless all of the Notes held by a Holder are to be redeemed. In connection with any redemption of Notes, any such notice of redemption may, at the Issuer’s discretion, state that such redemption is subject to one or more conditions precedent, including, but not limited to, completion of an equity offering, other offering, issuance of Indebtedness or other corporate transaction or event. In addition, if such notice of redemption is subject to satisfaction of one or more conditions precedent, such notice may state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed).

Exhibit A-11

(9) DENOMINATIONS, TRANSFER, EXCHANGE.

The Notes are in registered form without coupons in minimum denominations of €100,000 and integral multiples of €1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes (i) for a period beginning at the opening of business 15 days immediately preceding the sending of notice of redemption of Notes selected for redemption and ending at the close of business on the day such notice is sent or (ii) during the period between a record date and the corresponding Interest Payment Date.

(10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(11) AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture, the Notes and the Note Guarantees may be amended, supplemented or waived as provided in Article IX of the Base Indenture.

(12) DEFAULTS AND REMEDIES. If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy or insolvency of the Issuer, any of its Significant Subsidiaries or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary) and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the outstanding Notes, in each case, by notice to the Issuer, may declare the principal of, premium, if any, and accrued but unpaid interest, if any, on all the Notes to be due and payable; provided that no such declaration may be made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two years prior to such declaration. If an Event of Default relating to certain events of bankruptcy or insolvency of the Issuer, any of its Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. The requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture, this Supplemental Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

(13) TRUSTEE DEALINGS WITH ISSUER. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee.

(14) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, member, manager, partner, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, will have any liability for any obligations of the Issuer or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

Exhibit A-12

(15) AUTHENTICATION. This Note will not be valid until authenticated by the manual, facsimile or electronic (including PDF) signature of the Trustee or an authenticating agent.

(17) CUSIP AND ISIN NUMBERS AND COMMON CODES. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP and ISIN numbers and common codes to be printed on the Notes and the Trustee may use CUSIP and ISIN numbers and common codes in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers or codes either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.

The Notes of this Series shall be entitled to the benefits of the Note Guarantee of each Guarantor signatory hereto, or that may hereafter execute a supplemental indenture in accordance with Section 10.03 of the Base Indenture, each such Note Guarantee to be governed by Article X of the Base Indenture (including, without limitation, the provisions for release of such Note Guarantee in respect of the Notes of this Series pursuant to Section 10.04 of the Base Indenture).

The Notes of this Series shall be in minimum denominations of €100,000 and integral multiples of €1,000.

The terms and provisions contained in the Notes of this Series will constitute, and are hereby expressly made, a part of this Twenty-Third Supplemental Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Twenty-Third Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any such Note conflicts with the express provisions of this Twenty-Third Supplemental Indenture, the provisions of this Twenty-Third Supplemental Indenture shall govern and be controlling.

(b) Global Notes. Notes of this Series issued in global form will be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes of this Series issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note will represent such of the outstanding Notes of this Series as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes of this Series from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes of this Series represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes of this Series represented thereby will be made by the Trustee or the Notes Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof.

-4-

Section 2.03 Title and Terms of Notes.

The aggregate principal amount of Notes of this Series which shall be authenticated and delivered on the Series Issue Date under the Indenture shall be €1,000,000,000; provided, however, that the Issuer from time to time, without giving notice to or seeking the consent of the Holders of Notes of this Series, may issue additional notes (the “Additional Notes”) in any amount having the same terms as the Notes of this Series in all respects, except for the issue date, the issue price, the initial interest payment date and rights under a related registration rights agreement, if any. Any such Additional Notes shall be authenticated by the Trustee upon receipt of a Company Order to that effect, and when so authenticated, will constitute “Notes” for all purposes of the Indenture and will (together with all other Notes of this Series issued under the Indenture) constitute a single Series of Notes under the Indenture; provided that if such Additional Notes are not fungible with the Notes of this Series for U.S. federal income tax purposes, as applicable, as determined by the Issuer, such Additional Notes may have a separate CUSIP, ISIN, common code or other identifying number, as applicable.

(a) The Notes of this Series issued on the Series Issue Date will be issued at an issue price of 99.826% of the principal amount thereof.

(b) The principal amount of the Notes of this Series is due and payable in full as set forth in Exhibit A.

(c) The rate or rates at which the Notes of this Series shall bear interest, the date or dates from which such interest shall accrue, the interest payment date on which any such interest shall be payable and the regular record date for any interest payable on any interest payment date, in each case, shall be as set forth in the form of the Note as set forth in Exhibit A.

(f) All payments of interest and principal, including payments made upon any redemption of the Notes of this Series, will be payable in euros. If, on or after February 4, 2025, the euro is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the Issuer’s control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Notes of this Series and the related Note Guarantees as required pursuant to the Indenture will be made in U.S. dollars until the euro is again available to the Issuer or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recently available market exchange rate for euros, as determined in the Issuer’s sole discretion. Any payment in respect of the Notes of this Series so made in U.S. dollars will not constitute an Event of Default under the Notes of this Series or the Indenture.

(g) Additional Amounts.

All payments under or in respect of the Notes of this Series, or under or in respect of any related Note Guarantee, will be made free and clear of, and without deduction or withholding for or on account of, any present or future taxes, duties, assessments or other governmental charges of whatsoever nature imposed, levied, collected, withheld or assessed by the United States or any political subdivision or taxing authority of or in the United States (collectively, “Taxes”), unless such withholding or deduction is required by law.

In the event any such withholding or deduction of Taxes is required by law, subject to the limitations described below, the Issuer will pay to the Holder of any Note of this Series such additional amounts (“Additional Amounts”) as may be necessary in order that the net amount of each payment received by each beneficial owner (including upon redemption) that is a Non-U.S. Holder or an entity or arrangement treated as a partnership for U.S. federal income tax purposes one or more of the partners of which is a Non-U.S. Holder, after deduction or withholding for or on account of such Taxes, by any applicable withholding agent (including any such withholding or deduction in respect of Additional Amounts), will equal the amount provided for in such Note to be then due and payable before deduction or withholding for or on account of such Taxes.

Subject to the provisions of Section 8.06 hereof, all money and European Government Obligations deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or European Government Obligations in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or European Government Obligations held by the Trustee or Paying Agent.”

DEUTSCHE BANK TRUST COMPANY AMERICAS,

Exhibit A-6

[Form of Reverse Side of Initial Note]

3.500% Senior Notes due 2037 (the “Notes”)

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST.

Interest shall be computed on the basis of (i) the actual number of days in the period for which interest is being calculated and (ii) the actual number of days from and including the last date on which interest was paid on the Notes (or from and including February 11, 2025, if no interest has been paid on the Notes), to but excluding the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The amount of interest payable for any period shorter than a full monthly period shall be computed on the basis of the actual number of calendar days elapsed in such a period. Interest shall accrue on the principal amount of this Note from and including February 11, 2025 until maturity at a rate per annum equal to 3.500%.

The Issuer promises to pay interest annually in arrears on February 11 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that the first Interest Payment Date shall be February 11, 2026. If an interest payment date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next succeeding Business Day as if made on the date the payment was due, and no interest shall accrue for the intervening period.

(2) METHOD OF PAYMENT.

The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the Business Day immediately preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.14 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Issuer maintained for such purpose in London, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the books and records of the Registrar; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent.

All payments of interest and principal, including payments made upon any redemption of the Notes, will be payable in euros. If, on or after February 4, 2025, the euro is unavailable to the Issuer due to the imposition of exchange controls or other circumstances beyond the Issuer’s control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions

Exhibit A-7

by public institutions of or within the international banking community, then all payments in respect of the Notes and the related Note Guarantees as required pursuant to the Indenture will be made in U.S. dollars until the euro is again available to the Issuer or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recently available market exchange rate for euros, as determined in the Issuer’s sole discretion. Any payment in respect of the Notes so made in U.S. dollars will not constitute an Event of Default under the Notes or the Indenture.

[The Holder of a Definitive Note is not required to surrender such Definitive Note to the Trustee in order to receive payment of principal at maturity. Such Definitive Note, after payment has been made, shall be cancelled without the requirement of presentation.]³

(3) PAYING AGENT AND REGISTRAR.

Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

(4) INDENTURE.

The Issuer issued the Notes pursuant to an Indenture dated as of September 15, 2022 (the “Base Indenture”) among the Issuer, Parent and the Trustee, as amended and supplemented with respect to the Notes by the Twenty-Third Supplemental Indenture dated as of February 11, 2025 (the “Twenty-Third Supplemental Indenture”; the Base Indenture, as amended and supplemented with respect to the Notes by the Twenty-Third Supplemental Indenture, the “Indenture”).

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and to the Trust Indenture Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are senior unsecured, unsubordinated obligations of the Issuer. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

The Issuer’s obligations under the Notes are unconditionally guaranteed on a senior unsecured basis, to the extent set forth in the Indenture, by each of the Guarantors to the extent set forth in the Indenture.

Exhibit A-8

(5) OPTIONAL REDEMPTION.

Prior to November 11, 2036 (the “Par Call Date”), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest thereon to the redemption date.

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by the Issuer, a German government bond whose maturity is closest to the applicable Par Call Date of the Notes to be redeemed, or if such independent investment bank in its discretion determines that such similar bond is not in issue, such other German government bond as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German government bonds selected by the Issuer, determine to be appropriate for determining the Comparable Government Bond Rate.

“Comparable Government Bond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the Comparable Government Bond on the basis of the middle market price of the Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment bank selected by the Issuer.

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

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

The Trustee shall have no responsibility for calculating the redemption price for the Notes.

Exhibit A-9

Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. At or before 10:00 a.m. (London time) on the redemption date, the Issuer will deposit with the paying agent money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. If less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected in accordance with the procedures of Euroclear Bank SA/NV and Clearstream Banking, société anonyme, as applicable.

For the avoidance of doubt, the requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

(6) TAX REDEMPTION.

The Notes may be redeemed at the Issuer’s option, in whole but not in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, together with interest accrued and unpaid to the date fixed for redemption, at any time, on giving not less than 10 nor more than 60 days’ notice in accordance with “Notice of Redemption” below if:

(a) the Issuer has or will become obligated to pay Additional Amounts as a result of any change in or amendment to the laws, regulations or rulings of the United States or any political subdivision or any taxing authority of or in the United States affecting taxation, or any change in or amendment to an official application, or interpretation of such laws, regulations or rulings (including by virtue of a holding of a court of competent jurisdiction), which change or amendment is announced and becomes effective on or after February 4, 2025, or

(b) any action shall have been taken by a taxing authority, or any decision has been rendered by a court of competent jurisdiction, in the United States or any political subdivision or taxing authority of or in the United States, including any such actions specified in (a) above, whether or not such action was taken or brought, or such decision was rendered, with respect to the Issuer, in any such case on or after February 4, 2025, which action or decision results in a substantial likelihood that the Issuer will be required to pay Additional Amounts on the next interest payment date.

However, no such notice of redemption shall be given (1) earlier than 90 days prior to the earliest date on which the Issuer would be, in the case of a redemption for the reasons specified in (a) above, or on which there would be a substantial likelihood that the Issuer would be, in the case of a redemption for the reasons specified in (b) above, obligated to pay such Additional Amounts if a payment in respect of the Notes were then due and (2) unless, at the time such notification of redemption is given, such circumstances remain in effect.

Exhibit A-10

Prior to the publication of any notice of redemption pursuant to this section, the Issuer will deliver to the Trustee:

(1) a certificate signed by one of the Issuer’s duly authorized officers stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the Issuer’s right to redeem have occurred, and

(2) in the case of a redemption for the reasons specified in (a) or (b) above, a written opinion of independent legal counsel of recognized standing to the effect that the Issuer has or will become obligated to pay such Additional Amounts as a result of such change or amendment or that there is a substantial likelihood that the Issuer will be required to pay such Additional Amounts as a result of such action or decision, as the case may be.

Such notice, once delivered by the Issuer to the Trustee, will be irrevocable.

(7) MANDATORY REDEMPTION.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

(8) NOTICE OF REDEMPTION.

Notice of redemption will be sent at least 10 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed, except that redemption notices may be sent or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than €100,000 may be redeemed in part but only in whole multiples of €1,000, unless all of the Notes held by a Holder are to be redeemed. In connection with any redemption of Notes, any such notice of redemption may, at the Issuer’s discretion, state that such redemption is subject to one or more conditions precedent, including, but not limited to, completion of an equity offering, other offering, issuance of Indebtedness or other corporate transaction or event. In addition, if such notice of redemption is subject to satisfaction of one or more conditions precedent, such notice may state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed).

Exhibit A-11

(9) DENOMINATIONS, TRANSFER, EXCHANGE.

The Notes are in registered form without coupons in minimum denominations of €100,000 and integral multiples of €1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes (i) for a period beginning at the opening of business 15 days immediately preceding the sending of notice of redemption of Notes selected for redemption and ending at the close of business on the day such notice is sent or (ii) during the period between a record date and the corresponding Interest Payment Date.

(10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(11) AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture, the Notes and the Note Guarantees may be amended, supplemented or waived as provided in Article IX of the Base Indenture.

(12) DEFAULTS AND REMEDIES. If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy or insolvency of the Issuer, any of its Significant Subsidiaries or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary) and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the outstanding Notes, in each case, by notice to the Issuer, may declare the principal of, premium, if any, and accrued but unpaid interest, if any, on all the Notes to be due and payable; provided that no such declaration may be made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two years prior to such declaration. If an Event of Default relating to certain events of bankruptcy or insolvency of the Issuer, any of its Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. The requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture, this Supplemental Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

(13) TRUSTEE DEALINGS WITH ISSUER. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee.

(14) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, member, manager, partner, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, will have any liability for any obligations of the Issuer or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

Section 2.03 Title and Terms of Notes.

The aggregate principal amount of Notes of this Series which shall be authenticated and delivered on the Series Issue Date under the Indenture shall be €750,000,000; provided, however, that the Issuer from time to time, without giving notice to or seeking the consent of the Holders of Notes of this Series, may issue additional notes (the “Additional Notes”) in any amount having the same terms as the Notes of this Series in all respects, except for the issue date, the issue price, the initial interest payment date and rights under a related registration rights agreement, if any. Any such Additional Notes shall be authenticated by the Trustee upon receipt of a Company Order to that effect, and when so authenticated, will constitute “Notes” for all purposes of the Indenture and will (together with all other Notes of this Series issued under the Indenture) constitute a single Series of Notes under the Indenture; provided that if such Additional Notes are not fungible with the Notes of this Series for U.S. federal income tax purposes, as applicable, as determined by the Issuer, such Additional Notes may have a separate CUSIP, ISIN, common code or other identifying number, as applicable.

(a) The Notes of this Series issued on the Series Issue Date will be issued at an issue price of 99.710% of the principal amount thereof.

(b) The principal amount of the Notes of this Series is due and payable in full as set forth in Exhibit A.

The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the Board of Governors of the Federal Reserve System as of the close of business on the second Business Day prior to the relevant payment date or, if the Board of Governors of the Federal Reserve System has not announced a rate of conversion, on the basis of the most recently available market exchange rate for euros, as determined in the Issuer’s sole discretion. Any payment in respect of the Notes of this Series so made in U.S. dollars will not constitute an Event of Default under the Notes of this Series or the Indenture.
