Ladies and Gentlemen:

Smurfit Westrock Financing DAC, a designated activity company incorporated under the laws of Ireland with registered company number 774613 (the “Company”), a subsidiary of Smurfit Westrock plc (“Smurfit Westrock”), and the guarantors listed in Exhibit A hereto (together, the “Guarantors”), confirm their agreement with Citigroup Global Markets Inc. (“Citi”), the other Representatives (as defined below), and each of the other Underwriters named in Exhibit B hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 9 hereof, for whom Citi, Credit Agricole Securities (USA) Inc., Mizuho Securities USA LLC and Wells Fargo Securities, LLC are acting as representatives (in such capacity, the “Representatives”)), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts, if any, set forth in Exhibit B hereto opposite the name of such Underwriter of $800,000,000 aggregate principal amount of the Company’s 5.185% Senior Notes due 2036 (the “Notes”). The Notes will be issued pursuant to an Indenture, to be dated as of November 21, 2025 (the “Indenture”), among the Company, the Guarantors and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”). Certain terms of the Notes will be established pursuant to an officer’s certificate in accordance with Section 2.1 of the Indenture. The Notes shall be fully and unconditionally guaranteed as to the payment of principal, premium, if any, additional amounts, if any, and interest (the “Guarantees”) by the Guarantors.

The Company understands that the relevant Underwriters propose to make a public offering of the relevant Notes as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), and has prepared and filed with the Securities and Exchange Commission (the “Commission”) an “automatic shelf registration statement” (as defined under Rule 405 under the Securities Act) on Form S-3 (File No. 333-291446) in respect of the Issuer’s debt securities and guarantees thereof. Such registration statement, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (together, “Rule 430 Information”) is referred to herein as the “Registration Statement”. As used herein, the term “Base Prospectus” means the prospectus included in such Registration Statement (and any amendments thereto) at the time of its effectiveness that omits Rule 430 Information. The Company has prepared and previously delivered to you a preliminary prospectus supplement, dated November 17, 2025, relating to the Notes (the “Preliminary Prospectus Supplement”) and related to the Base Prospectus. The Preliminary Prospectus Supplement and the Base Prospectus, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, are hereinafter called, collectively, the “Pre-Pricing Prospectus.” Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a prospectus supplement, dated November 17, 2025, relating to the Notes (the “Prospectus Supplement”) and will file the Prospectus Supplement and the Base Prospectus with the Commission, all in accordance with the provisions of Rule 430B and Rule 424(b), and the Company has previously advised you of all information (financial and other) that will be set forth therein. The Prospectus Supplement and the Base Prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Notes (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, are herein called, collectively, the “Prospectus.”

The Company and the Guarantors will prepare a listing application (including the documents and information incorporated by reference therein, the “Listing Application”) for the Notes to be admitted to the Official List of the Irish Stock Exchange plc trading as Euronext Dublin (“Euronext Dublin”) and to trading on the Global Exchange Market (“GEM”) and added to the Euronext ESG Bonds platform in accordance with the rules of that exchange.

Each of the Company and the Guarantors hereby confirms that it has authorized the use of the Registration Statement, the General Disclosure Package (as defined herein), the Prospectus and any additional written documentation in connection with the offer and sale of Notes by the Underwriters in the manner contemplated by this Agreement.

The Underwriters understand that the Company intends to (a) use the net proceeds from the sale of the Notes (i) to redeem the outstanding $500.0 million in aggregate principal amount of 3.375% Senior Notes due 2027 issued by WRKCo Inc. (the “WRKCo 2027 Notes”) in full at the applicable redemption price set forth in the indenture governing the WRKCo 2027 Notes and (ii) for general corporate purposes, including the repayment of other indebtedness; and (b) use an amount equivalent to the proceeds of the Offering to finance or refinance a portfolio of Eligible Green Projects (as defined in the Prospectus) in accordance with Smurfit Westrock’s Green Finance Framework, which Smurfit Westrock may, in the future, update in line with developments in the market.

The Company and the Guarantors, subject to Section 3(b), will comply with the requirements of Rule 430B and Rule 433 and notify the Representatives immediately, and confirm the notice in writing, (i) of the receipt of any comments from the Commission to the Registration Statement, the General Disclosure Package or the Prospectus, (ii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Pre-Pricing Prospectus or the Prospectus or any Issuer Free Writing Prospectus or for additional information in connection therewith, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Pre-Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement to any of the foregoing or any notice from the Commission objecting to the use of the form of the Registration Statement or any post-effective amendment thereto, or of the suspension of the qualification of the Notes for offering or sale in any jurisdiction or of the loss or suspension of any exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the Securities Act concerning the Registration Statement and (iv) if the Company becomes the subject of a proceeding under Section 8A of the Securities Act in connection with the offering of the Notes. Subject to sub-section (e) below and other than as provided for therein, the Company and the Guarantors will make every reasonable effort to prevent the issuance of any stop order and the suspension or loss of any qualification of the Notes for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued, or any such suspension or loss occurs, to obtain the lifting thereof at the earliest possible moment. The Company shall pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1)(i) of the Securities Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act Regulations, except to the extent such filing fees have been paid prior to the date hereof.

(b)           Filing of Amendments. The Company and the Guarantors will give the Representatives notice of their intention to file or prepare any amendment to the Registration Statement, any Issuer Free Writing Prospectus or any amendment, supplement or revision to the Pre-Pricing Prospectus, the Prospectus or any Issuer Free Writing Prospectus, whether pursuant to the Securities Act or otherwise, and the Company will furnish the Representatives with copies of any such documents within a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object promptly after reasonably notice thereof. The Company has given the Representatives notice of any filings made pursuant to the Exchange Act or the Exchange Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time through the Closing Date (or, if later, through the end of the period during which the Prospectus is required (or, but for the provisions of Rule 172, would be required) to be delivered by applicable law (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise)) and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object promptly after reasonable notice thereof.

16

(c)           Delivery of Registration Statements. The Company and the Guarantors have furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, copies of the Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and copies of all consents and certificates of experts.

(d)           Continued Compliance with Securities Laws. The Company and the Guarantors will comply with the Securities Act, the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations so as to permit the completion of the distribution of the Notes as contemplated by this Agreement, the General Disclosure Package and the Prospectus. If at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by the applicable law to be delivered in connection with sales of the Notes (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), any event shall occur or condition shall exist as a result of which it is necessary to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) so that the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading or if it is necessary to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) in order to comply with the requirements of the Securities Act, the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations, the Company and the Guarantors will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement and will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or post-effective amendment to the Registration Statement, the Company and the Guarantors will use their best efforts to have such amendment declared or become effective as soon as practicable and the Company and the Guarantors will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time an Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary to amend or supplement such Issuer Free Writing Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading, or if it is necessary to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the Securities Act or the Securities Act Regulations, the Company and the Guarantors will promptly notify the Representatives of such event or condition and of their intention to file such amendment or supplement and will promptly prepare and, if required by the Securities Act or the Securities Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company and the Guarantors will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

17

(e)           Blue Sky and Other Qualifications. The Company and the Guarantors will cooperate with the Underwriters and their counsel in connection with the qualification of the Notes and the Guarantees for offer and sale, or to obtain an exemption for the Notes and the Guarantees to be offered or sold, under the securities or blue sky laws of such jurisdictions as the Underwriters shall reasonably request and to comply with such laws and to continue such qualification in effect so long as reasonably required for distribution of the Notes; provided that the Company and each Guarantor shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(f)            Rule 158. The Company and the Guarantors will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act.

(g)           Use of Proceeds. The Company will apply the net proceeds from the sale of the Notes as described in each of the General Disclosure Package and the Prospectus, as such Prospectus may be amended or supplemented from time to time, under the heading “Use of Proceeds”.

(h)           Restriction on Sale of Notes. During the period beginning after the date hereof and continuing until the Closing Date, the Company and each of the Guarantors and their respective affiliates will not, directly or indirectly, offer, sell, contract to sell, issue, pledge or otherwise dispose of, enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) of any debt securities or guarantees thereof (except relating to the potential offering by Smurfit Kappa Treasury Unlimited Company of euro-denominated senior notes, as disclosed in the General Disclosure Package and the Prospectus) without the consent of the Representatives (which consent will not be unreasonably withheld).

(i)            No Stabilization and Manipulation. Neither the Company nor any of the Guarantors will take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Notes. The Company and each of the Guarantors authorize the Representatives to make adequate public disclosure of the information required by the Market Abuse Regulation (EU No 596/2014) or that regulation as it forms part of UK laws by virtue of European Union (Withdrawal) Act 2018 (the “EUWA”) (“MAR”) and any applicable delegated regulations thereunder, including the related U.K. Financial Conduct Authority’s rules and guidance including the Code of Market Conduct. The Company and each of the Guarantors and their respective affiliates will not take any action or omit to take any action, as communicated by the Underwriters, which may result in any of the Underwriters being unable to rely upon the exemption for stabilization described in Article 5 of MAR or any other safe harbor or exemption for stabilization provided for under any applicable law, regulations or rules (including any stock exchange rules) in the jurisdiction where such stabilization is effected.

(j)            Reporting Requirements. The Company and the Guarantors, during the period when the Prospectus is required (or, but for the provisions of Rule 172, would be required) by applicable law to be delivered (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), will file all documents required to be filed with the Commission pursuant to the Exchange Act and the Exchange Act Regulations within the time periods required by the Exchange Act and the Exchange Act Regulations.

18

(k)           Preparation of Prospectus. Immediately following the execution of this Agreement, the Company and the Guarantors will, subject to Section 3(b) hereof, prepare the Prospectus, which shall contain the public offering price and terms of the Notes, the plan of distribution thereof and such other information as may be required by the Securities Act or the Securities Act Regulations or as the Representatives and the Company or the Guarantors may deem appropriate, and will file or transmit for filing with the Commission, in accordance with the provisions of Rule 430B and in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), the Prospectus.

(l)            New Registration Statement. If, immediately prior to the third anniversary of the initial effective date of the Registration Statement (the “Renewal Deadline”), any of the Notes remains unsold by the Underwriters, the Company and the Guarantors will, prior to the Renewal Deadline, if they have not already done so and are eligible to do so, file a new automatic shelf registration statement relating to the Notes, and notify the Representatives when such filing has been made. If any Guarantor is no longer eligible to file an automatic shelf registration statement, the Company and the Guarantors will, prior to the Renewal Deadline, if they have not already done so, file a new registration statement relating to the Notes, and notify the Representatives when such filing has been made and use their best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline and will take all other action as is necessary or appropriate to permit the public offering and sale of the Notes to continue as contemplated in the expired registration statement relating to the Notes. References in this Agreement to the “Registration Statement” shall include any such new registration statement from and after the time it is filed with the Commission, mutatis mutandis.

(m)           DTC. The Company will assist the Underwriters in arranging for the Notes to be eligible for clearance and settlement through DTC and to maintain such eligibility for so long as the Notes remain outstanding.

(n)           Stamp duties and taxes. The Company and the Guarantors will jointly and severally indemnify and hold harmless the Underwriters against any documentary, stamp or similar issuance tax, including any interest and penalties, whether in Ireland or in any Relevant Taxing Jurisdiction, on the creation, issuance and/or delivery to the Underwriters of the Notes, and on the execution and/or delivery of this Agreement and any of the other Transaction Documents in each case save for any such taxes, duties, fees or charges which arise or are increased as a result of:

(i)           any document being voluntarily registered in any jurisdiction; and

(ii)          any document effecting the registration, issue or delivery of the Notes either being signed or executed in the United Kingdom or being brought into the United Kingdom;

(o)           Pricing Term Sheet. The Company will prepare the pricing term sheet (the “Pricing Term Sheet”) reflecting the final terms of the Notes, in substantially the form attached hereto as Exhibit C and otherwise in form and substance satisfactory to the Representatives, and shall file each such Pricing Term Sheet as an “issuer free writing prospectus” pursuant to, and as required by, Rule 433; provided that the Company shall furnish the Representatives with copies of any such Pricing Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall object.

19

(p)           Currency. The Company agrees that all amounts payable hereunder shall be paid in U.S. dollars and made without withholding or deduction for or on account of any present or future taxes, levies, imposts, duties, charges or other deductions or withholdings levied in any Relevant Taxing Jurisdiction from or through which payment is made, unless such deduction or withholding is required by applicable law; and in that event, the Company shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made (except for any taxes which may be imposed on a holder of the Notes as a result of such holder (a) being resident for tax purposes (or having a permanent establishment) in or having a present or former connection to any Relevant Tax Jurisdiction excluding any connection arising solely from the acquisition, ownership or holding of the Notes or (b) failing to provide any documentation that would have reduced or eliminated such tax, withholding or deduction).

(q)           VAT. All amounts chargeable by the Underwriters under this Agreement shall be exclusive of VAT. If any VAT is properly chargeable on any amounts charged by any Underwriter then such amounts shall be charged together with an amount equal to any VAT chargeable on the relevant supply. Such amount equal to VAT shall be payable upon delivery of an appropriate valid VAT invoice in respect of the supply to which the charge relates. Any amount for which the Underwriters are to be reimbursed under this Agreement will be reimbursed together with an amount equal to any irrecoverable VAT, where appropriate.

(r)            Announcements. Prior to the completion of the distribution of the Notes, neither the Company nor any of the Guarantors will issue any press release or other communication directly or indirectly or hold any press conference (except for routine communications in the ordinary course of business consistent with past practice) with respect to Smurfit Westrock or any of its subsidiaries, the condition, financial or otherwise, or the earnings, business affairs or business prospects of Smurfit Westrock or any of its subsidiaries, without the prior consent of the Representatives (such consent not to be unreasonably withheld), unless in the judgment of the Company and the Guarantors and their counsel, and after notification to the Representatives, such press release or communication is required by law or under the rules of Euronext Dublin, the London Stock Exchange or the New York Stock Exchange or except as issued in accordance with the Securities Act and the rules and regulations promulgated thereunder.

(s)           Exchange Listing. The Company will (i) use its best commercial efforts to cause the Notes to be listed on the Official List of Euronext Dublin and admitted to trading on the GEM as soon as practicable after the Closing Date but in no event later than the date of the first interest payment on the Notes; (ii) deliver to Euronext Dublin copies of the Registration Statement, the Prospectus and such other documents, information and commercially reasonable undertakings as may be required pursuant to the GEM rules or otherwise in connection with obtaining such listing; and (iii) maintain such listing of the Notes for so long as any of the Notes are outstanding. If the Notes cease to be listed on the Official List of Euronext Dublin, the Company shall use its commercially reasonable efforts to promptly list the Notes on a stock exchange to be agreed between the Company and the Representatives.

20

SECTION 6.          Indemnification. (a) The Company and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Underwriter, the directors, officers and affiliates of each Underwriter and each person, if any, who controls any Underwriter within the meaning of either 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 the legal fees and other 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, any untrue statement or alleged untrue statement of a material fact contained in any of the Registration Statement, the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433) or “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus (and, in each case, any amendment or supplement thereto if the Company shall have furnished any amendments or supplements thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 information relating to any Underwriter furnished to the Company and the Guarantors in writing by such Underwriter expressly for use therein as set forth in Section 12(a).

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, their respective directors and officers and each person, if any, who controls the Company or any of the Guarantors within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company and each of the Guarantors to each Underwriter, but only with reference to the information set forth in Section 12(a) relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in any of the Registration Statement, the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433) filed or required to be filed pursuant to Rule 433(d) (and, in each case, any amendment or supplement thereto if the Company shall have furnished any amendments or supplements thereto).

24

(c) 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 indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity 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 paragraph (a) or (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 otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person, the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the costs and expenses of such proceeding and the fees and expenses of such counsel related to such proceeding. 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 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. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such reasonable 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 such Underwriter and any such separate firm for the Company, the Guarantors, their respective directors and officers and such control persons of the Company and the Guarantors 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 for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, which consent will not be unreasonably withheld, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement 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 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.

25

SECTION 7.          Contribution. If the indemnification provided for in the first and second paragraphs of Section 6 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 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand and the Underwriters on the other hand from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors, on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Notes (before deducting expenses) received by the Company, and the total discounts and commissions received by the Underwriters, bear to the aggregate offering price of the Notes. The relative fault of the Company and the Guarantors 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 or any Guarantor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

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 the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim (together with any irrecoverable VAT, withholding or other tax thereon). Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Notes purchased by it were offered 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 the respective principal amount of the Notes set forth opposite their names in Exhibit B hereto, and not joint.

The remedies provided for in Section 6 above and in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The respective indemnities, rights of contribution contained in Sections 6 and  7, reimbursement rights contained in Section 8(b), representations, warranties, agreements and other statements of the Company, the Guarantors, the officers of the Company or a Guarantor and of each Underwriter set forth in this Agreement shall survive the delivery of and payment for the Notes and shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company or a Guarantor, their respective officers, directors or any other person controlling the Company or a Guarantor and (iii) acceptance of and payment for any of the Notes.

26

SECTION 8.          Termination of Agreement.

(a)           Termination; General. Notwithstanding anything herein contained, this Agreement may be terminated in the absolute discretion of the Representatives, by notice given 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 or by, as the case may be, any of Euronext Dublin, the Luxembourg Stock Exchange, the New York Stock Exchange, the Nasdaq stock market, the London Stock Exchange or the over-the-counter market; (ii) trading of any securities of or guaranteed by Smurfit Westrock or any of its subsidiaries shall have been suspended on any exchange or in any over-the-counter market or settlement in such trading shall have been materially disrupted; (iii) a general moratorium on commercial banking activities shall have been declared by Irish, Luxembourg, United States Federal or New York State authorities or by the competent governmental or regulatory authorities in the United Kingdom; (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity, crisis, or emergency either within or outside the United States that, in the reasonable judgment of the Representatives is material and adverse and which, in the reasonable judgment of such Representatives, makes it impracticable to proceed with the offering, sale or delivery of the Notes on the terms and in the manner contemplated by this Agreement, the General Disclosure Package and the Prospectus or (v) an adverse change shall have occurred in the United States, the United Kingdom or Ireland taxation affecting the Notes or the transfer thereof (other than as disclosed in the General Disclosure Package and the Prospectus) or exchange controls shall have been imposed by the United States, the United Kingdom or Ireland.

(b)           Reimbursement of Costs and Expenses. If this Agreement (i) is terminated pursuant to Section 8 or (ii) shall be terminated by the Underwriters, or any of them, (X) because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or (Y) if for any reason the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company and each of the Guarantors jointly and severally agree to reimburse the Underwriters or such Underwriter as has so terminated this Agreement with respect to itself for all out-of-pocket costs and expenses (including the reasonable fees and expenses of its counsel, and, where applicable, with any irrecoverable VAT thereon) reasonably incurred by the Underwriters or such Underwriter in connection with this Agreement or the offering contemplated hereunder.

SECTION 9.          Default by One or More of the Underwriters.

(a)           If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Notes that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Notes by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriter do not arrange for the purchase of such Notes, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to such non-defaulting Underwriter to purchase such Notes on such terms. If other persons become obligated or agree to purchase the Notes of a defaulting Underwriter, either the non-defaulting Underwriter or the Company may postpone the Closing Date for up to five full Business Days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the General Disclosure Package, the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the General Disclosure Package or the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriters” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Exhibit B hereto that, pursuant to this Section 9, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

27

(b)           If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriter and the Company as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Notes, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Notes that such Underwriter agreed to purchase hereunder) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)           If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of the Notes that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Notes or if the Company shall not exercise the rights described in paragraph (b) above, then this Agreement shall terminate without liability on the part of any non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 8(b) hereof and except that the provisions of Section 6 hereof shall not terminate and shall remain in effect.

(d)           Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Guarantors or any non-defaulting Underwriter for damages caused by its default.

SECTION 10.        Authority of Representatives. Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

SECTION 11.        Parties. This Agreement shall inure to the benefit of and be binding upon the Company, the Guarantors, the Underwriters, each affiliate (including any parent or holding company) of any Underwriter which assists such Underwriter in the distribution of the Notes (including the indemnified persons referred to in Section 6 hereof), any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

28

(b)           Waiver of Immunity. To the extent that the Company or any of the Guarantors or any of their properties, assets or revenues may have or may hereafter become entitled to, or have attributed to it, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from set-off or counterclaim, from the competent jurisdiction of any court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any competent jurisdiction in which proceedings may at any time be commenced, with respect to their obligations, liabilities or any other matter under or arising out of or in connection with this Agreement, any of the other Transaction Documents or any of the transactions contemplated hereby or thereby, the Company and each of the Guarantors hereby irrevocably and unconditionally waive, and agree not to plead or claim, any such immunity and consent to such relief and enforcement.

The Company and each of the Guarantors irrevocably waive the defense of an inconvenient forum or objections to personal jurisdiction with respect to the maintenance of such legal suit, action or proceeding. To the extent permitted by law, the Company and each of the Guarantors hereby waive any objections to the enforcement by any competent court in Ireland or in the Netherlands of any judgment validly obtained in any such court in New York on the basis of any such legal suit, action or proceeding. Each of the Company and the Guarantors hereby appoint Smurfit WestRock US Holdings Corporation, with offices located at 1000 Abernathy Road NE, Atlanta, GA 30328, USA, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such legal suit, action or proceeding. Such appointment shall be irrevocable. The Company and each of the Guarantors hereby represent and warrant that the Authorized Agent has accepted such appointment and irrevocably agreed to act as said agent for service of process, and the Company and the Guarantors agree to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. The Company and the Guarantors further agree that service of process upon the Authorized Agent and written notice of said service to the Company and the Guarantors shall be deemed in every respect effective service of process upon the Company and the Guarantors in any such legal suit, action or proceeding. If for any reason the Authorized Agent shall cease to be available to act as such, each of the Company and the Guarantors agrees to promptly designate a new designee, appointee and agent in New York City on the terms and for the purposes of this provision satisfactory to the Representatives under this Agreement. Nothing herein shall affect the right of any Underwriter or any person controlling any Underwriter to serve process in any other manner permitted by law.

As Representatives of the several Underwriters

Ladies and Gentlemen:

Smurfit Kappa Treasury Unlimited Company, a public unlimited company incorporated under the laws of Ireland with registered company number 177324 (the “Company”), a subsidiary of Smurfit Westrock plc (“Smurfit Westrock”), and the guarantors listed in Exhibit A hereto (together, the “Guarantors”), confirm their agreement with Citigroup Global Markets Limited (“Citi”), the other Representatives (as defined below), and each of the other Underwriters named in Exhibit B hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 9 hereof, for whom Citi, Barclays Bank Ireland PLC, Commerzbank Aktiengesellschaft and Goodbody Stockbrokers UC are acting as representatives (in such capacity, the “Representatives”)), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts, if any, set forth in Exhibit B hereto opposite the name of such Underwriter of €500,000,000 aggregate principal amount of the Company’s 3.489% Senior Notes due 2031 (the “Notes”). The Notes will be issued pursuant to an Indenture, to be dated as of November 21, 2025 (the “Indenture”), among the Company, the Guarantors and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as supplemented on November 24, 2025 by an officer’s certificate in accordance with Section  2.1 of the Indenture. The Notes shall be fully and unconditionally guaranteed as to the payment of principal, premium, if any, additional amounts, if any, and interest (the “Guarantees”) by the Guarantors.

The Company understands that the relevant Underwriters propose to make a public offering of the relevant Notes as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), and has prepared and filed with the Securities and Exchange Commission (the “Commission”) an “automatic shelf registration statement” (as defined under Rule 405 under the Securities Act) on Form S-3 (File No. 333-291446) in respect of the Issuer’s debt securities and guarantees thereof. Such registration statement, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (together, “Rule 430 Information”) is referred to herein as the “Registration Statement”. As used herein, the term “Base Prospectus” means the prospectus included in such Registration Statement (and any amendments thereto) at the time of its effectiveness that omits Rule 430 Information. The Company has prepared and previously delivered to you a preliminary prospectus supplement, dated November 18, 2025, relating to the Notes (the “Preliminary Prospectus Supplement”) and related to the Base Prospectus. The Preliminary Prospectus Supplement and the Base Prospectus, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, are hereinafter called, collectively, the “Pre-Pricing Prospectus.” Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a prospectus supplement, dated November 18, 2025, relating to the Notes (the “Prospectus Supplement”) and will file the Prospectus Supplement and the Base Prospectus with the Commission, all in accordance with the provisions of Rule 430B and Rule 424(b), and the Company has previously advised you of all information (financial and other) that will be set forth therein. The Prospectus Supplement and the Base Prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Notes (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, are herein called, collectively, the “Prospectus.”

The Company and the Guarantors will prepare a listing application (including the documents and information incorporated by reference therein, the “Listing Application”) for the Notes to be admitted to the Official List of the Irish Stock Exchange plc trading as Euronext Dublin (“Euronext Dublin”) and to trading on the Global Exchange Market (“GEM”) and added to the Euronext ESG Bonds platform in accordance with the rules of that exchange.

Each of the Company and the Guarantors hereby confirms that it has authorized the use of the Registration Statement, the General Disclosure Package (as defined herein), the Prospectus and any additional written documentation in connection with the offer and sale of Notes by the Underwriters in the manner contemplated by this Agreement.

The Underwriters understand that the Company intends to (a) use the net proceeds from the sale of the Notes and the substantially concurrent offering of US-dollar denominated senior notes (i) to redeem the outstanding €750.0 million in aggregate principal amount of 1.500% Senior Notes due 2027 issued by Smurfit Kappa Treasury Unlimited Company (the “SKT 2027 Notes”) in full at the applicable redemption price set forth in the indenture governing the SKT 2027 Notes, (ii) to redeem the outstanding $500.0 million in aggregate principal amount of 3.375% Senior Notes due 2027 issued by WRKCo Inc. (the “WRKCo 2027 Notes”) in full at the applicable redemption price set forth in the indenture governing the WRKCo 2027 Notes and (iii) for general corporate purposes, including the repayment of indebtedness; and (b) use an amount equivalent to the proceeds of the Offering to finance or refinance a portfolio of Eligible Green Projects (as defined in the Prospectus) in accordance with Smurfit Westrock’s Green Finance Framework, which Smurfit Westrock may, in the future, update in line with developments in the market.

The term “Transaction Documents” is used in this Underwriting Agreement (this “Agreement”) to refer collectively to this Agreement, the Notes, the Indenture (including the Guarantees set forth therein), and any other agreement or instrument to be entered into in conjunction with the offering of the Notes. For the purposes of this Agreement, the term “Notes” shall be deemed to include the Guarantees, where applicable. Certain terms used in this Agreement are defined in Section 21 hereof.

Payment for the Notes shall be made by wire transfer in immediately available funds to the account(s) specified by the Company to the Representatives no later than 12:00 P.M. (London time) on November 24, 2025 (or at such other time on the same or such other date as the Representatives and the Company may otherwise agree in writing) (such time and date of payment and delivery being herein called the “Closing Date”) against delivery of the Global Notes to a common depositary of Euroclear Bank, SA/NV as operator of the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”) or their respective nominees, for the account of the Underwriters, with any transfer taxes payable in connection with the initial sale of the Notes duly paid by the Company. The Global Notes will be made available for inspection by the Representatives at the office of the Trustee (or as otherwise agreed) not later than 1:00 P.M., London time, on the Business Day prior to the Closing Date.

It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Notes which it has agreed to purchase. Citi, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Notes to be purchased by any Underwriter whose funds have not been received by the Closing Date, but such payment shall not relieve such Underwriter from its obligations hereunder.

The Underwriters agree as between themselves that they will be bound by and will comply with the International Capital Market Association Standard Form Agreement Among Managers Version 1 / New York Law Schedule (the “Agreement Among Managers”) and further agree that (i) references in the Agreement Among Managers to the “Lead Manager” shall mean the Representatives, references to the “Joint Bookrunners” shall mean the Representatives, references to the “Settlement Lead Manager” shall mean Citigroup Global Markets Limited and references to the “Stabilising Manager” shall mean Citigroup Global Markets Limited and (ii) Clause 3 of the Agreement Among Managers shall not apply. For the purposes of the Agreement Among Managers, each Underwriter’s Commitment (as defined in the Agreement Among Managers) is set out opposite its name in Exhibit B to this Agreement and references to “Securities” shall mean the Notes. Where there are any inconsistencies between this Agreement and the Agreement Among Managers, the terms of this Agreement shall prevail. Notwithstanding anything contained in the Agreement Among Managers, each Underwriter hereby agrees that the Settlement Lead Manager may allocate such Underwriter’s pro rata share of expenses incurred by the Underwriters in connection with the offering of the Notes 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.

SECTION 3.         Covenants of the Company. The Company and the Guarantors jointly and severally covenant with each Underwriter as follows:

The Company shall pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1)(i) of the Securities Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act Regulations, except to the extent such filing fees have been paid prior to the date hereof.

16

17

(d) Continued Compliance with Securities Laws. The Company and the Guarantors will comply with the Securities Act, the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations so as to permit the completion of the distribution of the Notes as contemplated by this Agreement, the General Disclosure Package and the Prospectus. If at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by the applicable law to be delivered in connection with sales of the Notes (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), any event shall occur or condition shall exist as a result of which it is necessary to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) so that the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading or if it is necessary to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) in order to comply with the requirements of the Securities Act, the Securities Act Regulations, the Exchange Act and the Exchange Act Regulations, the Company and the Guarantors will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement and will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or post-effective amendment to the Registration Statement, the Company and the Guarantors will use their best efforts to have such amendment declared or become effective as soon as practicable and the Company and the Guarantors will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time an Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary to amend or supplement such Issuer Free Writing Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading, or if it is necessary to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the Securities Act or the Securities Act Regulations, the Company and the Guarantors will promptly notify the Representatives of such event or condition and of their intention to file such amendment or supplement and will promptly prepare and, if required by the Securities Act or the Securities Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company and the Guarantors will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(e) Blue Sky and Other Qualifications. The Company and the Guarantors will cooperate with the Underwriters and their counsel in connection with the qualification of the Notes and the Guarantees for offer and sale, or to obtain an exemption for the Notes and the Guarantees to be offered or sold, under the securities or blue sky laws of such jurisdictions as the Underwriters shall reasonably request and to comply with such laws and to continue such qualification in effect so long as reasonably required for distribution of the Notes; provided that the Company and each Guarantor shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

18

(f)       Rule 158. The Company and the Guarantors will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the Securities Act.

(g) Use of Proceeds. The Company will apply the net proceeds from the sale of the Notes as described in each of the General Disclosure Package and the Prospectus, as such Prospectus may be amended or supplemented from time to time, under the heading “Use of Proceeds”.

(h) Restriction on Sale of Notes. During the period beginning after the date hereof and continuing until the Closing Date, the Company and each of the Guarantors and their respective affiliates will not, directly or indirectly, offer, sell, contract to sell, issue, pledge or otherwise dispose of, enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) of any debt securities or guarantees thereof (except relating to the substantially concurrent offering by Smurfit Westrock Financing DAC of 5.185% Senior Notes due 2036) without the consent of the Representatives (which consent will not be unreasonably withheld).

(i)         No Stabilization and Manipulation. Neither the Company nor any of the Guarantors will take, directly or indirectly, any action (i) designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Notes or (ii) that would result in the loss by the Underwriters of the ability to rely on any stabilization safe harbor provided by the Securities Act or the FSMA. The Company and each of the Guarantors authorize the Representatives to make adequate public disclosure of the information required by the Market Abuse Regulation (EU No 596/2014) or that regulation as it forms part of UK laws by virtue of European Union (Withdrawal) Act 2018 (the “EUWA”) (“MAR”) and any applicable delegated regulations thereunder, including the related U.K. Financial Conduct Authority’s rules and guidance including the Code of Market Conduct. The Company and each of the Guarantors and their respective affiliates will not take any action or omit to take any action, as communicated by the Underwriters, which may result in any of the Underwriters being unable to rely upon the exemption for stabilization described in Article 5 of MAR or any other safe harbor or exemption for stabilization provided for under any applicable law, regulations or rules (including any stock exchange rules) in the jurisdiction where such stabilization is effected.

(j)          Reporting Requirements. The Company and the Guarantors, during the period when the Prospectus is required (or, but for the provisions of Rule 172, would be required) by applicable law to be delivered (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), will file all documents required to be filed with the Commission pursuant to the Exchange Act and the Exchange Act Regulations within the time periods required by the Exchange Act and the Exchange Act Regulations.

(k) Preparation of Prospectus. Immediately following the execution of this Agreement, the Company and the Guarantors will, subject to Section 3(b) hereof, prepare the Prospectus, which shall contain the public offering price and terms of the Notes, the plan of distribution thereof and such other information as may be required by the Securities Act or the Securities Act Regulations or as the Representatives and the Company or the Guarantors may deem appropriate, and will file or transmit for filing with the Commission, in accordance with the provisions of Rule 430B and in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), the Prospectus.

19

(l)          New Registration Statement. If, immediately prior to the third anniversary of the initial effective date of the Registration Statement (the “Renewal Deadline”), any of the Notes remains unsold by the Underwriters, the Company and the Guarantors will, prior to the Renewal Deadline, if they have not already done so and are eligible to do so, file a new automatic shelf registration statement relating to the Notes, and notify the Representatives when such filing has been made. If any Guarantor is no longer eligible to file an automatic shelf registration statement, the Company and the Guarantors will, prior to the Renewal Deadline, if they have not already done so, file a new registration statement relating to the Notes, and notify the Representatives when such filing has been made and use their best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline and will take all other action as is necessary or appropriate to permit the public offering and sale of the Notes to continue as contemplated in the expired registration statement relating to the Notes. References in this Agreement to the “Registration Statement” shall include any such new registration statement from and after the time it is filed with the Commission, mutatis mutandis.

(m) Euroclear/Clearstream. The Company will assist the Underwriters in arranging for the Notes to be eligible for clearance and settlement through the facilities of Euroclear/Clearstream and to maintain such eligibility for so long as the Notes remain outstanding.

(n) Stamp duties and taxes. The Company and the Guarantors will jointly and severally indemnify and hold harmless the Underwriters against any documentary, stamp or similar issuance tax, including any interest and penalties, whether in Ireland or in any Relevant Taxing Jurisdiction, on the creation, issuance and/or delivery to the Underwriters of the Notes, and on the execution and/or delivery of this Agreement and any of the other Transaction Documents in each case save for any such taxes, duties, fees or charges which arise or are increased as a result of:

(i) any document being voluntarily registered in any jurisdiction; and

(ii)        any document effecting the registration, issue or delivery of the Notes either being signed or executed in the United Kingdom or being brought into the United Kingdom;

(o) Pricing Term Sheet. The Company will prepare the pricing term sheet (the “Pricing Term Sheet”) reflecting the final terms of the Notes, in substantially the form attached hereto as Exhibit C and otherwise in form and substance satisfactory to the Representatives, and shall file each such Pricing Term Sheet as an “issuer free writing prospectus” pursuant to, and as required by, Rule 433; provided that the Company shall furnish the Representatives with copies of any such Pricing Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall object.

(p) Currency. The Company agrees that all amounts payable hereunder shall be paid in euro and made without withholding or deduction for or on account of any present or future taxes, levies, imposts, duties, charges or other deductions or withholdings levied in any Relevant Taxing Jurisdiction from or through which payment is made, unless such deduction or withholding is required by applicable law; and in that event, the Company shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made (except for any taxes which may be imposed on a holder of the Notes as a result of such holder (a) being resident for tax purposes (or having a permanent establishment) in or having a present or former connection to any Relevant Tax Jurisdiction excluding any connection arising solely from the acquisition, ownership or holding of the Notes or (b) failing to provide any documentation that would have reduced or eliminated such tax, withholding or deduction).

20

(q) VAT. All amounts chargeable by the Underwriters under this Agreement shall be exclusive of VAT. If any VAT is properly chargeable on any amounts charged by any Underwriter then such amounts shall be charged together with an amount equal to any VAT chargeable on the relevant supply. Such amount equal to VAT shall be payable upon delivery of an appropriate valid VAT invoice in respect of the supply to which the charge relates. Any amount for which the Underwriters are to be reimbursed under this Agreement will be reimbursed together with an amount equal to any irrecoverable VAT, where appropriate.

(r) Announcements. Prior to the completion of the distribution of the Notes, neither the Company nor any of the Guarantors will issue any press release or other communication directly or indirectly or hold any press conference (except for routine communications in the ordinary course of business consistent with past practice) with respect to Smurfit Westrock or any of its subsidiaries, the condition, financial or otherwise, or the earnings, business affairs or business prospects of Smurfit Westrock or any of its subsidiaries, without the prior consent of the Representatives (such consent not to be unreasonably withheld), unless in the judgment of the Company and the Guarantors and their counsel, and after notification to the Representatives, such press release or communication is required by law or under the rules of Euronext Dublin, the London Stock Exchange or the New York Stock Exchange or except as issued in accordance with the Securities Act and the rules and regulations promulgated thereunder.

(s) Exchange Listing. The Company will (i) use its best commercial efforts to cause the Notes to be listed on the Official List of Euronext Dublin and admitted to trading on the GEM as soon as practicable after the Closing Date but in no event later than the date of the first interest payment on the Notes; (ii) deliver to Euronext Dublin copies of the Registration Statement, the Prospectus and such other documents, information and commercially reasonable undertakings as may be required pursuant to the GEM rules or otherwise in connection with obtaining such listing; and (iii) maintain such listing of the Notes for so long as any of the Notes are outstanding. If the Notes cease to be listed on the Official List of Euronext Dublin, the Company shall use its commercially reasonable efforts to promptly list the Notes on a stock exchange to be agreed between the Company and the Representatives.

SECTION 6.        Indemnification. (a) The Company and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Underwriter, the directors, officers and affiliates of each Underwriter and each person, if any, who controls any Underwriter within the meaning of either 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 the legal fees and other 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, any untrue statement or alleged untrue statement of a material fact contained in any of the Registration Statement, the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433) or “road show” (as defined in Rule 433) that does not constitute an Issuer Free Writing Prospectus (and, in each case, any amendment or supplement thereto if the Company shall have furnished any amendments or supplements thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 information relating to any Underwriter furnished to the Company and the Guarantors in writing by such Underwriter expressly for use therein as set forth in Section 12(a).

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, their respective directors and officers and each person, if any, who controls the Company or any of the Guarantors within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company and each of the Guarantors to each Underwriter, but only with reference to the information set forth in Section 12(a) relating to such Underwriter furnished to the Company in writing by such Underwriter expressly for use in any of the Registration Statement, the Pre-Pricing Prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or in any “issuer information” (as defined in Rule 433) filed or required to be filed pursuant to Rule 433(d) (and, in each case, any amendment or supplement thereto if the Company shall have furnished any amendments or supplements thereto).

25

(c) 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 indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity 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 paragraph (a) or (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 otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person, the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the costs and expenses of such proceeding and the fees and expenses of such counsel related to such proceeding. 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 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. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such reasonable 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 such Underwriter and any such separate firm for the Company, the Guarantors, their respective directors and officers and such control persons of the Company and the Guarantors 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 for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, which consent will not be unreasonably withheld, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement 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 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.

SECTION 7.         Contribution. If the indemnification provided for in the first and second paragraphs of Section 6 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 (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand and the Underwriters on the other hand from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors, on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Notes (before deducting expenses) received by the Company, and the total discounts and commissions received by the Underwriters, bear to the aggregate offering price of the Notes. The relative fault of the Company and the Guarantors 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 or any Guarantor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

26

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 the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim (together with any irrecoverable VAT, withholding or other tax thereon). Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Notes purchased by it were offered 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 the respective principal amount of the Notes set forth opposite their names in Exhibit B hereto, and not joint.

The remedies provided for in Section  6 above and in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The respective indemnities, rights of contribution contained in Sections 6 and 7, reimbursement rights contained in Section 8(b), representations, warranties, agreements and other statements of the Company, the Guarantors, the officers of the Company or a Guarantor and of each Underwriter set forth in this Agreement shall survive the delivery of and payment for the Notes and shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company or a Guarantor, their respective officers, directors or any other person controlling the Company or a Guarantor and (iii) acceptance of and payment for any of the Notes.

SECTION 8.        Termination of Agreement.

(a) Termination; General. Notwithstanding anything herein contained, this Agreement may be terminated in the absolute discretion of the Representatives, by notice given 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 or by, as the case may be, any of Euronext Dublin, the Luxembourg Stock Exchange, the New York Stock Exchange, the Nasdaq stock market, the London Stock Exchange or the over-the-counter market; (ii) trading of any securities of or guaranteed by Smurfit Westrock or any of its subsidiaries shall have been suspended on any exchange or in any over-the-counter market or settlement in such trading shall have been materially disrupted; (iii) a general moratorium on commercial banking activities shall have been declared by Irish, Luxembourg, United States Federal or New York State authorities or by the competent governmental or regulatory authorities in the United Kingdom; (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity, crisis, or emergency either within or outside the United States that, in the reasonable judgment of the Representatives is material and adverse and which, in the reasonable judgment of such Representatives, makes it impracticable to proceed with the offering, sale or delivery of the Notes on the terms and in the manner contemplated by this Agreement, the General Disclosure Package and the Prospectus or (v) an adverse change shall have occurred in the United States, the United Kingdom or Ireland taxation affecting the Notes or the transfer thereof (other than as disclosed in the General Disclosure Package and the Prospectus) or exchange controls shall have been imposed by the United States, the United Kingdom or Ireland.

27

(b) Reimbursement of Costs and Expenses. If this Agreement (i) is terminated pursuant to Section 8 or (ii) shall be terminated by the Underwriters, or any of them, (X) because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or (Y) if for any reason the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company and each of the Guarantors jointly and severally agree to reimburse the Underwriters or such Underwriter as has so terminated this Agreement with respect to itself for all out-of-pocket costs and expenses (including the reasonable fees and expenses of its counsel, and, where applicable, with any irrecoverable VAT thereon) reasonably incurred by the Underwriters or such Underwriter in connection with this Agreement or the offering contemplated hereunder.

SECTION 9.      Default by One or More of the Underwriters.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Notes that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Notes by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriter do not arrange for the purchase of such Notes, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to such non-defaulting Underwriter to purchase such Notes on such terms. If other persons become obligated or agree to purchase the Notes of a defaulting Underwriter, either the non-defaulting Underwriter or the Company may postpone the Closing Date for up to five full Business Days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the General Disclosure Package, the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the General Disclosure Package or the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriters” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Exhibit B hereto that, pursuant to this Section 9, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

28

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriter and the Company as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Notes, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Notes that such Underwriter agreed to purchase hereunder) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of the Notes that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Notes or if the Company shall not exercise the rights described in paragraph (b) above, then this Agreement shall terminate without liability on the part of any non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 8(b) hereof and except that the provisions of Section 6 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Guarantors or any non-defaulting Underwriter for damages caused by its default.

SECTION 10. Authority of Representatives. Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

SECTION 11. Parties. This Agreement shall inure to the benefit of and be binding upon the Company, the Guarantors, the Underwriters, each affiliate (including any parent or holding company) of any Underwriter which assists such Underwriter in the distribution of the Notes (including the indemnified persons referred to in Section 6 hereof), any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 12. Miscellaneous.

(a) Blood Letter. The parties hereto acknowledge and agree that, for all purposes of this Agreement, the information furnished to the Company by the Underwriters for inclusion in each of the General Disclosure Package and the Prospectus, consists solely of:

The Company and each of the Guarantors irrevocably waive the defense of an inconvenient forum or objections to personal jurisdiction with respect to the maintenance of such legal suit, action or proceeding.

Each of the Company and the Guarantors hereby appoint Smurfit WestRock US Holdings Corporation, with offices located at 1000 Abernathy Road NE, Atlanta, GA 30328, United States, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such legal suit, action or proceeding. Such appointment shall be irrevocable. The Company and each of the Guarantors hereby represent and warrant that the Authorized Agent has accepted such appointment and irrevocably agreed to act as said agent for service of process, and the Company and the Guarantors agree to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. The Company and the Guarantors further agree that service of process upon the Authorized Agent and written notice of said service to the Company and the Guarantors shall be deemed in every respect effective service of process upon the Company and the Guarantors in any such legal suit, action or proceeding. If for any reason the Authorized Agent shall cease to be available to act as such, each of the Company and the Guarantors agrees to promptly designate a new designee, appointee and agent in New York City on the terms and for the purposes of this provision satisfactory to the Representatives under this Agreement. Nothing herein shall affect the right of any Underwriter or any person controlling any Underwriter to serve process in any other manner permitted by law. The provisions of this Section 12(c) are intended to be effective upon the execution of this Agreement without any further action by the Company or any of the Guarantors and the introduction of a true copy of this Agreement into evidence shall be conclusive and final evidence as to such matters.

30

(d) WAIVER OF JURY TRIAL. EACH OF THE COMPANY AND THE GUARANTORS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

The Company and each of the Guarantors shall jointly and severally indemnify and hold harmless the Underwriters against any loss incurred by them as a result of any judgment or order being given or made and expressed and paid in a currency (the “Judgment Currency”) other than euro and as a result of any variation as between (i) the rate of exchange at which the euro amount, as the case may be, is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in London at which such Underwriters on the first Business Day after the payment of such judgment or order are able to purchase euro, as the case may be, with the amount of the Judgment Currency actually received by such Underwriters. The foregoing shall constitute a separate and independent obligation of the Company and the Guarantors and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” as used in this paragraph shall include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, euro, as the case may be.

** Delivery of the Notes will be made to investors on or about November 24, 2025, which will be the fourth business day in New York following the date of pricing of the Notes (such settlement being referred to as “T+4”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise.

Purchasers of the Notes who wish to trade the Notes on a date that is prior to the first business day prior to delivery of the Notes should consult their own advisor.

The Notes are not intended to be offered, sold or otherwise made available to, and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (the “EEA”). For these purposes, a retail investor means a person who is one (or more) of (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”), (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II, or (iii) not a “qualified investor” as defined in Article 2 of Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (the “UK”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA. Consequently, no key information document required by the PRIIPs Regulation as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and, therefore, offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

In the UK, this final term sheet is for distribution only to persons who (i) have professional experience in matters relating to investments and qualifying as investment professionals falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended, the “Financial Promotion Order”), (ii) are persons falling within Article 49(2)(a) to (d) (“high net worth companies, unincorporated associations etc.”) of the Financial Promotion Order, or (iii) are persons to whom an invitation or inducement to engage in investment activity (within the meaning of section 21 of the FSMA) in connection with the issue or sale of any securities may otherwise lawfully be communicated or caused to be communicated (all such persons together being referred to as “relevant persons”). In the UK, this final term sheet is directed only at relevant persons and must not be acted on or relied on by persons who are not relevant persons. Any investment or investment activity to which this document relates is available in the UK only to relevant persons and, in the UK, will be engaged in only with relevant persons.

Solely for the purposes of the product approval process of the manufacturers, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients only, each as defined in MiFID II; and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, and without prejudice to the Issuer’s obligations in accordance with MiFID II, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the such Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook, and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; and (ii) all channels for distribution of such securities to eligible counterparties and professional clients are appropriate. Any distributor should take into consideration the manufacturers’ target market assessment; however, a distributor subject to the FCA Handbook Intervention and Product Governance Sourcebook is responsible for undertaking its own target market assessment in respect of such securities (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

If such form or terms have been so established, the Trustee shall not be required to authenticate such Notes if the issue of such Notes pursuant to this Indenture in accordance with a Board Resolution will materially adversely affect the Trustee’s own rights, duties or immunities under the Notes and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 2.1 and of the preceding paragraph, if all Notes of a series are not to be originally issued at one time, it shall not be necessary, unless the Trustee reasonably determines otherwise, for the Issuer to deliver a Board Resolution, Officers’ Certificate or supplemental indenture otherwise required pursuant to Section 2.1 or the Issuer Order and Opinion of Counsel otherwise required pursuant to the third paragraph of this Section at or prior to the authentication of each Note of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Note of such series to be issued.

Each Note shall be dated the date of its authentication.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for in Exhibits A and B executed by the Trustee by manual, facsimile or electronic signature, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Issuer, and the Issuer shall deliver such Note to the Trustee for cancellation as provided in Section 2.10, for all purposes of this Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

The Trustee may appoint an authenticating agent (“Authenticating Agent”) reasonably acceptable to the Issuer to authenticate Notes of any series. Unless otherwise provided in the appointment, an Authenticating Agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such Authenticating Agent. An Authenticating Agent has the same rights as an Agent to deal with the Issuer and Affiliates of the Issuer. The Trustee initially appoints the Registrar as Authenticating Agent of the Notes of each series and the Issuer hereby confirms that such appointment is acceptable to it. The Trustee may change an Authenticating Agent without prior notice to the relevant Holders; provided that such Authenticating Agent is acceptable to the Issuer of the relevant series of Notes.

SECTION 2.5. Temporary Securities. Pending the preparation of Definitive Notes of any series, the Issuer may execute, and upon an Issuer Order the Trustee shall authenticate and deliver, temporary Notes that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued, and with such appropriate insertions, omissions, substitutions and other variations as the Officers executing such Notes may determine, as evidenced by their execution of such Notes.

If temporary Notes of any series are issued, the Issuer will cause Definitive Notes of that series to be prepared without unreasonable delay. After the preparation of Definitive Notes of such series, the temporary Notes of such series shall be exchangeable for Definitive Notes of such series upon surrender of the temporary Notes of such series at the office or agency of the Issuer in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes of any series, the Issuer shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more Definitive Notes of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. Until so exchanged, the temporary Notes of any series shall in all respects be entitled to the same benefits under this Indenture as Definitive Notes of such series and tenor.

SECTION 2.6. Registration; Registration of Transfer and Exchange. The Issuer shall maintain an office or agency where (a) Definitive Notes may be presented or surrendered for registration of transfer or for exchange (such office or agency, the “Registrar”), (b) Global Notes (and Definitive Notes, if issued) may be presented or surrendered for payment (“Paying Agent”) and (c) notices and demands in respect of such Global Notes (and Definitive Notes, if issued) and this Indenture may be served. The Registrar shall keep a register (the “Register”) of the Definitive Notes and of their transfer and exchange. Notices and demands in respect of Global Notes shall be made by the Issuer in accordance with Section 12.1. The Issuer, upon written notice to the Trustee, may have one or more co-Registrars and one or more additional Paying Agents reasonably acceptable to the Trustee. For each series of Notes denominated in a Non-Dollar Currency, the applicable Issuer shall appoint a separate Paying Agent under a supplemental indenture, which supplemental indenture shall be in form and substance acceptable to such Paying Agent. Money held by such Paying Agent shall be held as banker, not subject to the UK FCA Client Money Rules, and need not be segregated except as required by law. The term “Paying Agent” includes any additional Paying Agent. The term “Registrar” includes any co-Registrar.

The Issuer initially appoints Deutsche Bank Trust Company Americas as Paying Agent, transfer agent (the “Transfer Agent”) and Registrar, until such time as any such entity has resigned or a successor has been appointed unless another Paying Agent is appointed prior to the time the Notes of any applicable series are first issued. In the event that a Paying Agent, Registrar or Transfer Agent is replaced, the Issuer will (so long as the Notes are Global Notes) provide written notice thereof to the Trustee in accordance with Section 12.1. The Issuer may change any Paying Agent, Registrar or Transfer Agent for a series of Notes without prior notice to the Holders thereof. Smurfit Westrock or any of its Subsidiaries may act as Paying Agent or Registrar in respect of the Notes.

23

Upon surrender for registration of transfer of any Note of a series at the office or agency of the Issuer in a Place of Payment for that series, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of the same series, of any authorized denominations and of like tenor and aggregate principal amount.

At the option of the Holder, Notes of any series (except a Global Note) may be exchanged for other Notes of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive.

All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Notes surrendered upon such registration of transfer or exchange.

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuer or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Notes, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Section 2.5, Section 3.7 or Section 10.4 not involving any transfer.

If the Notes of any series (or of any series and specified tenor) are to be redeemed in part, neither the Issuer nor the Trustee shall be required (A) to issue, register the transfer of or exchange any Notes of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Notes selected for redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

The provisions of clauses (a), (b), (c) and (d) below shall apply only to Global Notes:

(a)           Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Note or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

24

(b)           Notwithstanding any other provision in this Indenture, and subject to such applicable provisions, if any, as may be specified as contemplated by Section 2.1, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Note or a nominee thereof unless (1) such Depositary has notified the Issuer that it is unwilling or unable to continue as Depositary for such Global Note or, if applicable, has ceased to be a Depositary registered under the Exchange Act, and a successor Depositary is not appointed by the Issuer within 90 days after the Issuer’s receipt of such notice, (2) there shall have occurred and be continuing an Event of Default with respect to such Global Note and the Registrar has received a request from the Depositary to issue Definitive Notes in lieu of the Global Notes, (3) the Issuer shall determine in its sole discretion that Notes of a series issued in global form shall no longer be represented by a Global Note, or (4) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 2.1, then in any such case, such Global Note may be exchanged by such Depositary for Definitive Notes of the same series, of any authorized denomination and of a like aggregate principal amount and tenor, registered in the names of, and the transfer of such Global Note or portion thereof may be registered to, such Persons as such Depositary shall direct. If the Issuer designates a successor Depositary pursuant to clause (1) above, such Global Note shall promptly be exchanged in whole for one or more other Global Notes registered in the name of the successor Depositary, whereupon such designated successor shall be the Depositary for such successor Global Note or Global Notes and the provisions of clauses (a), (b), (c) and (d) of this Section shall continue to apply thereto.

(c)           Subject to clause (b) above and to such applicable provisions, if any, as may be specified as contemplated by Section 2.1, any exchange of a Global Note for other Notes may be made in whole or in part, and all Notes issued in exchange for a Global Note or any portion thereof shall be registered in such names as the Depositary for such Global Note shall direct.

(d)           Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Notes or any portion thereof, whether pursuant to this Section, Section 2.5, Section 2.7, Section 3.7 or Section 10.4 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Note, unless such Note is registered in the name of a Person other than the Depositary for such Global Note or a nominee thereof.

SECTION 2.7. Mutilated, Destroyed, Lost and Stolen Notes. If any mutilated Note is surrendered to the Trustee, the Issuer shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Note of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding and shall cancel and dispose of such mutilated Note in accordance with its customary procedures.

If there shall be delivered to the Issuer and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Issuer or the Trustee that such Note has been acquired by a bona fide purchaser, the Issuer shall execute and the Trustee shall authenticate and deliver, in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Issuer in its discretion may, instead of issuing a new Note, pay such Note.

25

Upon the issuance of any new Note, the Issuer may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel to the Issuer and the fees and expenses of the Trustee and its counsel) connected therewith.

Every new Note of any series issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes.

SECTION 2.8. Payment of Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 2.1 with respect to any series of Notes, interest on any Note which is payable, and is punctually paid or duly provided for, on any interest payment date shall be paid to the Person in whose name that Note (or one or more predecessor Notes) is registered at the close of business on the Record Date for such interest.

Any interest on any Note of any series which is payable, but is not punctually paid or duly provided for, on any interest payment date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in clause (a) or (b) below:

(a)           The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes of such series (or their respective predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note of such series and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee, in consultation with the Issuer, shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuer of such Special Record Date and, in the name and at the expense of the Issuer, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Notes of such series in the manner set forth in Section 12.2, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes of such series (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

26

(b)           The Issuer may make payment of any Defaulted Interest on the Notes of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and Section 2.6, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

SECTION 2.9. Persons Deemed Owners. Except as otherwise contemplated by Section 2.1 with respect to any series of Notes, prior to due presentment for registration of transfer of any Definitive Note, the Issuer, the Trustee, the Paying Agent, the Registrar or any co-Registrar may deem and treat the Person in whose name such Definitive Note is registered as the absolute owner of such Definitive Note for the purpose of receiving payment of principal of, premium and Additional Amounts, if any, and (subject to Section 2.6 and Section 2.8) any interest on such Definitive Note and for all other purposes whatsoever, whether or not such Definitive Note is overdue, and none of the Issuer, the Trustee, the Paying Agent, the Registrar or any co-Registrar shall be affected by notice to the contrary.

No holder of any beneficial interest in any Global Note held on its behalf by a Depositary shall have any rights under this Indenture with respect to such Global Note, and such Depositary may be treated by the Issuer, the Trustee, the Paying Agent, the Registrar or any co-Registrar as the absolute owner of such Global Note for all purposes whatsoever. None of the Issuer, the Trustee, the Paying Agent, the Registrar or any co-Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of Beneficial Ownership interests of a Global Note or for maintaining, supervising or reviewing any records relating to such Beneficial Ownership interests.

SECTION 2.10. Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and, if not already cancelled, shall be promptly cancelled by it. The Issuer may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuer may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Issuer has not issued and sold, and all Notes so delivered shall be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary procedures as directed by an Issuer Order, and the Trustee shall thereafter deliver to the Issuer a certificate with respect to such disposition.

27

SECTION 2.11. Computation of Interest. Except as otherwise specified as contemplated by Section 2.1 for Notes of any series, interest on the Notes of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

SECTION 2.12. CUSIP and ISIN Numbers. The Issuer, in issuing the Notes of any series, may use “CUSIP” or “ISIN” numbers (in addition to the other identification numbers printed on the Notes), if then in use, and, if so, the Trustee shall use such “CUSIP” or “ISIN” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such “CUSIP” or “ISIN” numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such “CUSIP” or “ISIN” numbers. The Issuer will promptly notify the Trustee of any change in the “CUSIP” or “ISIN” numbers.

SECTION 2.13. Outstanding Notes. Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those canceled by it, those delivered to it for cancellation, those reductions in any Global Note effected in accordance with the provisions hereof and those described in this Section 2.13 as not outstanding. Subject to Section 2.14, a Note does not cease to be outstanding because the Issuer or any of its Affiliates holds the Note.

If a Note is replaced pursuant to Section 2.7 (other than a mutilated Note surrendered for replacement), it shall cease to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. A mutilated Note shall cease to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.7.

If the principal amount of any Note is considered paid under Section 4.1, it shall cease to be outstanding and interest, and Additional Amounts, if any, on it shall cease to accrue.

If, on a Redemption Date or the maturity date of any series of Notes, the Paying Agent holds cash in Dollars or the applicable Non-Dollar Currency sufficient to pay all of the principal of, premium and Additional Amounts, if any, and interest on the Notes payable on that date, then on and after that date, the Notes will cease to be outstanding and interest and Additional Amounts, if any, on the Notes will cease to accrue.

For each series of Notes denominated in a Non-Dollar Currency, the principal amount of such Notes that shall be deemed to be outstanding and used to determine whether the necessary Holders have given any request, demand, authorization, direction, notice, consent or waiver shall be the Dollar equivalent, as determined by the Issuer of the relevant series of Notes by reference to the noon buying rate in New York for cable transfers for such currency, as such rate is certified for customs purposes by the Federal Reserve Bank of New York on the date of original issuance of such Notes, of the principal amount of such Notes.

SECTION 2.14. Treasury Notes. In determining whether the Holders of the required principal amount of any series of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or its Affiliates shall be disregarded, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Trust Officer of the Trustee actually knows are so owned shall be disregarded.

28

ARTICLE III

REDEMPTION

SECTION 3.1. Optional Redemption. Notes of any series that are redeemable before their maturity shall be redeemable, as a whole or from time to time in part, in accordance with their respective terms and (except as otherwise specified as contemplated by Section 2.1 for Notes of any series) in accordance with this Article III. The Issuer is not required to make mandatory redemption or sinking fund payments with respect to any series of Notes, except as may be specified as contemplated by Section 2.1 for such series.

SECTION 3.2. Election to Redeem; Notices to Trustee. The election of the Issuer to redeem any Notes shall be established in or pursuant to a Board Resolution or an Officers’ Certificate or in another manner specified, in each case, as contemplated by Section 2.1 for such Notes.

Except as otherwise established in or pursuant to a Board Resolution or an Officers’ Certificate or in another manner specified, in each case, as contemplated by Section 2.1 for such Notes, if the Issuer elects to redeem the Notes of a series pursuant to paragraphs 7 or 8 of such Notes, it shall notify the Trustee and the Paying Agent in writing of the Redemption Date and the principal amount of such Notes to be redeemed at least 10 days (unless a shorter period is acceptable to the Trustee and the applicable Paying Agent) but not more than 60 days (unless a longer period is acceptable to the Trustee and the applicable Paying Agent) before the Redemption Date. The Issuer shall give notice of redemption as required under the relevant paragraph of the Notes pursuant to which such Notes are being redeemed. Any such notice may be canceled at any time prior to the mailing of such notice of redemption to any Holder and shall thereupon be void and of no effect.

SECTION 3.3. Selection of Notes to Be Redeemed. Except as otherwise established in or pursuant to a Board Resolution or an Officers’ Certificate or in another manner specified, in each case, as contemplated by Section 2.1 for such Notes, if less than all of the Notes of a series are to be redeemed pursuant to their terms or the terms of this Indenture at any time, the Trustee or the Registrar will select Notes for redemption in compliance with the requirements of the principal securities exchange, if any, on which the Notes are listed, and in compliance with the requirements of the Depositary, or if the Notes are not so listed or such exchange prescribes no method of selection and the Notes are not held through the Depositary or the Depositary prescribes no method of selection, on a prorata basis; provided, however, that no Note of $200,000 in aggregate principal amount or less, or other than in an integral multiple of $1,000 in excess thereof (or in the case of Notes denominated in a Non-Dollar Currency, the equivalent thereof in each case (rounded to an integral multiple of 1,000 units of such Non-Dollar Currency)), shall be redeemed in part. In the event of partial redemption, the particular Notes to be redeemed shall be selected, unless otherwise specified as contemplated by Section 2.1 for Notes of any series, not less than 10 nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Notes not previously called for redemption.

29

SECTION 3.4. Notice of Redemption. Except as otherwise established in or pursuant to a Board Resolution or an Officers’ Certificate or in another manner specified, in each case, as contemplated by Section 2.1 for such Notes, notice of redemption shall be given by first-class mail, postage prepaid, mailed or otherwise in accordance with the applicable procedures of the Depositary not less than 10 nor more than 60 days prior to the Redemption Date (or within such period as otherwise specified as contemplated by Section 2.1 for the relevant Notes), to each Holder of Notes to be redeemed, at such Holder’s address appearing in the Register.

Except as otherwise established in or pursuant to a Board Resolution or an Officers’ Certificate or in another manner specified, in each case, as contemplated by Section 2.1 for such Notes, all notices of redemption shall identify the Notes to be redeemed and shall state:

(a)           the Redemption Date;

(b)           the Redemption Prices, including the amount of accrued and unpaid interest, if any, and Additional Amounts, if any, to be paid (subject to the right of Holders of record of Definitive Notes on the relevant Record Date to receive interest and Additional Amounts, if any, due on the relevant interest payment date);

(c)           the Record Date;

(d)           the name and address of the Paying Agent;

(e)           that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price, including accrued and unpaid interest, if any, and Additional Amounts, if any;

(f)            that, unless the Issuer defaults in making the redemption payment, interest and Additional Amounts, if any, on Notes called for redemption cease to accrue on and after the Redemption Date, and the only remaining right of the Holders of such Notes is to receive payment of the Redemption Price upon surrender to the Paying Agent of the Notes redeemed;

(g)           (i) if any Global Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date, interest and Additional Amounts, if any, shall cease to accrue on the portion called for redemption, and upon surrender of such Global Note, such Global Note with a notation on Schedule A thereof adjusting the principal amount thereof to be equal to the unredeemed portion, will be returned and (ii) if any Definitive Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed, and that, after the Redemption Date, upon surrender of such Definitive Note, a new Definitive Note or Notes in aggregate principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof, upon cancellation of the original Note;

(h)           if fewer than all the Notes are to be redeemed, the identification of the particular Notes (or portion thereof) to be redeemed, as well as the aggregate principal amount of Notes to be redeemed and the aggregate principal amount of Notes to be outstanding after such partial redemption;

(i)            the paragraph of the Notes pursuant to which such Notes are to be redeemed;

30

(j)            the CUSIP or ISIN, and that no representation is made as to the correctness or accuracy of the CUSIP or ISIN, if any, listed in such notice or printed on such Notes; and

(k)           whether the redemption is conditional on any events and, if so, a detailed explanation of such conditions.

Notice of redemption of Notes to be redeemed at the election of the Issuer shall be given by the Issuer or, at the Issuer’s request (which may be rescinded or revoked at any time prior to the time at which the Trustee shall have given such notice to the Holders), by the Trustee in the name and at the expense of the Issuer. The notice, if sent in the manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or otherwise in accordance with the applicable procedures of the Depositary or any defect in the notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Securities.

Any redemption or notice may, at the Issuer’s discretion, be subject to one or more conditions precedent and, at the Issuer’s discretion, the Redemption Date may be delayed until such time as any or all such conditions precedent included at the Issuer’s discretion shall be satisfied (or waived by the Issuer) or the Redemption Date may not occur and such notice may be rescinded if all such conditions precedent included at the Issuer’s discretion shall not have been satisfied (or waived by the Issuer). In addition, such notice may provide that payment of the Redemption Price and performance of the Issuer’s obligations with respect to such redemption may be performed by another person.

SECTION 3.5. Effect of Notice of Redemption. Once notice of redemption is given in accordance with Section 3.4, Notes called for redemption, subject to the satisfaction of any applicable conditions, shall become due and payable on the Redemption Date and at the Redemption Price, including accrued and unpaid interest, if any, and Additional Amounts, if any. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price (which shall include accrued and unpaid interest thereon, if any, and Additional Amounts, if any, to the Redemption Date), but (in the case of Definitive Notes) installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant Record Dates.

SECTION 3.6. Deposit of Redemption Price. Except as otherwise established in or pursuant to a Board Resolution or an Officers’ Certificate or in another manner specified, in each case, as contemplated by Section 2.1 for such Notes, with respect to the Notes of a series denominated in Dollars, prior to 10:00 a.m., New York time, and, with respect to the Notes of a series denominated in any Non-Dollar Currency, prior to 11:00 a.m., London time, or as advised by the applicable Paying Agent in relation to any Non-Dollar Currency other than euro and pounds sterling, or, in each case, such other time as may be agreed by the Issuer of the relevant series of Notes and the applicable Paying Agent, on the Redemption Date, subject to the satisfaction of any applicable conditions, the Issuer shall deposit with the Trustee or its designated Paying Agent in immediately available funds money sufficient to pay the Redemption Price, including any premium, if applicable, accrued and unpaid interest, if any, and Additional Amounts, if any, of all Notes to be redeemed on that date. The Paying Agent shall promptly return to the Issuer any funds so deposited which is not required for that purpose upon the written request of the Issuer.

31

For the avoidance of doubt, the calculation or determination of the Redemption Price, and any applicable premium, shall not be the obligation or responsibility of the Trustee or Paying Agent.

If the Issuer complies with the preceding paragraph, then, unless the Issuer defaults in the payment of such Redemption Price, including any premium, if applicable, accrued and unpaid interest, if any, and Additional Amounts, if any, interest and Additional Amounts, if any, on the Notes to be redeemed will cease to accrue on and after the Redemption Date, whether or not such Notes are presented for payment. With respect to Definitive Notes, if a Definitive Note is redeemed on or after a Record Date but on or prior to the related interest payment date, then any accrued and unpaid interest and Additional Amounts, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest and Additional Amounts, if any, shall be paid on the unpaid principal from the Redemption Date until such principal is paid at the rate provided in the Note.

The Issuer and each Guarantor hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

SECTION 4.3. Money for Notes Payments to Be Held in Trust. If the Issuer shall at any time act as its own Paying Agent with respect to any series of Notes, it will, on or before each due date of the principal of, premium or Additional Amounts, if any, and interest on any of the Notes of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal of, premium and Additional Amounts, if any, and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act.

Whenever the Issuer shall have one or more Paying Agents for any series of Notes, it will, on or prior to 10:00 a.m., New York City time, with respect to the Notes of a series denominated in Dollars, or 10:00 a.m., London time, with respect to the Notes of a series denominated in any Non-Dollar Currency, or as advised by the applicable Paying Agent in relation to any Non-Dollar Currency other than euro and pounds sterling, on each due date of the principal of, premium or Additional Amounts, if any, and interest on any Notes of that series, deposit (or, if the Issuer has deposited any trust funds with a trustee pursuant to Section 9.4(a), cause such trustee to deposit) with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the TIA, and (unless such Paying Agent is the Trustee) the Issuer will promptly notify the Trustee of its action or failure so to act.

The Issuer will cause each Paying Agent for any series of Notes other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold all sums held by it for the payment of the principal of, premium and Additional Amounts, if any, or interest on the Notes of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; (2) give the Trustee notice of any default by the Issuer (or any other obligor upon the Notes of that series) in the making of any payment of principal of, premium and Additional Amounts, if any, or interest on the Notes of that series; and (3) during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Notes of that series.

The Issuer may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by an Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Issuer or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from any further liability with respect to such money.

Subject to any applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of principal of, premium and Additional Amounts, if any, or interest on any Note of any series and remaining unclaimed for two years after such principal of, premium and Additional Amounts, if any, or interest on such Note has become due and payable shall be paid to the Issuer on request, or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer and the Guarantors for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease.

SECTION 4.4. Reports by the Issuer and the Guarantors. If any of the Issuer or a Guarantor is subject to the requirements of Section 13 or 15(d) of the Exchange Act, the Issuer or such Guarantor, as applicable, shall file with the Trustee and transmit to Holders, within 15 days after it files the same with the Commission, copies of the annual reports, information, documents and other reports that the Issuer or the Guarantor, as applicable, is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, or any other rules and regulations prescribed by the Commission. The Issuer or the Guarantor, as applicable, shall be deemed to have furnished such reports, information and documents referred to in this Section 4.4 to the Trustee and the Holders if the Issuer or the Guarantor, as applicable, has filed such reports, information and documents with the Commission via the EDGAR filing system or any successor system and such reports, information and documents are publicly available. Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s or the Guarantor’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate). The Trustee shall have no obligation to determine if and when the Issuer’s statements or reports are publicly available and accessible electronically.

SECTION 4.5. Statements as to Compliance. The Issuer and the Guarantors shall deliver to the Trustee, within 180 days after the end of each fiscal year of the Ultimate Parent, a written statement signed by the principal executive officer, principal financial officer or principal accounting officer of the Issuer and the Guarantors (complying with Section 314(a)(4) of the TIA), stating that:

(1)           a review of the activities of the Issuer and the Guarantors during such year and of performance under this Indenture has been made under his or her supervision; and

(2)           to the best of his or her knowledge, based on such review, the Issuer and the Guarantors are in compliance with all conditions and covenants under this Indenture.

SECTION 4.6. Negative Pledge. So long as any Notes of a particular series are outstanding, Smurfit Westrock shall not, and shall not permit any of its Subsidiaries to, secure any Indebtedness for money borrowed by placing a Lien (other than a Permitted Lien) on any Principal Property now or hereafter owned or leased by Smurfit Westrock or any of its Subsidiaries or on any shares of stock of any of their respective Subsidiaries (a “Restricted Lien”) without equally and ratably securing (or securing on a senior basis, in the case of a Lien securing Indebtedness that is by its terms expressly subordinated to the Notes of such series or any Guarantee) all of the Notes of such series, unless after giving effect thereto the aggregate principal amount of all such Indebtedness secured by a Restricted Lien then outstanding would not exceed an amount equal to 15% of Consolidated Net Tangible Assets. The restrictions set forth in the preceding sentence shall not apply to any Permitted Lien, and all Indebtedness secured by a Permitted Lien shall be excluded in computing the amount of Indebtedness secured by a Lien outstanding for purposes of this Section 4.6.

Any Lien created for the benefit of the holders of the Notes of any series pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Lien relating to such Indebtedness that gave rise to the obligation to so secure such Notes.

SECTION 4.7. Additional Amounts.

(a)           With respect to any series of Notes, if any deduction or withholding for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (collectively, “Taxes”) imposed or levied by or on behalf of (i) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (ii) any jurisdiction from or through which payment on the Notes of such series or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (i) and (ii), a “Relevant Taxing Jurisdiction”), shall at any time be required from any payments made with respect to the Notes of such series or the Guarantees, including payments of principal, Redemption Price, interest or premium, if any, the Payor or the relevant Guarantor, as applicable, shall pay (together with such payments) such additional amounts pursuant to Paragraph 2 of the Notes (“Additional Amounts”).

Upon written request, the Payor and each Guarantor shall use commercially reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes and will provide such certified copies to each Holder. The Payor and each Guarantor or successor Guarantor shall attach to each certified copy a certificate stating (x) that the amount of withholding Taxes evidenced by the certified copy was paid in connection with payments in respect of the principal amount of Notes then outstanding and (y) the amount of such withholding Taxes paid per $1,000 principal amount of the Notes.

35

(d)           Wherever in this Indenture or the Notes of such series there are mentioned, in any context, (i) the payment of principal, (ii) purchase prices in connection with a purchase of Notes, (iii) interest or (iv) any other amount payable on or with respect to the Notes of such series or the Guarantees, such reference shall be deemed to include payment of Additional Amounts as described in this Indenture and such Notes to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

(e)           The Issuer shall indemnify the Trustee and the Paying Agent for, and hold them harmless against, any loss, liability or expense incurred without negligence, willful default or fraud on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished to them pursuant to this Section 4.7.

(f)            Obligations under this Section 4.7 shall survive any termination, defeasance or discharge of this Indenture.

SECTION 4.8. Payment of Non-Income Taxes and Similar Charges. The Payor and each Guarantor or successor Guarantor shall pay any present or future stamp, court or documentary taxes, or any other excise or property taxes, charges or similar levies which arise in any jurisdiction from the execution, delivery or registration of the Notes of any series or any other document or instrument referred to herein or therein (other than a transfer of Notes subsequent to the initial offering of such Notes), or the receipt of any payments with respect to the Notes of any series, excluding any such taxes, charges or similar levies imposed by any jurisdiction outside a Relevant Taxing Jurisdiction, other than those resulting from, or required to be paid in connection with, the enforcement of the Notes of such series, the Guarantees or any other such document or instrument following the occurrence of any Event of Default with respect to such Notes. Obligations under this Section 4.8 will survive any termination, defeasance or discharge of this Indenture.

39

(5)           any other Event of Default provided as contemplated by Section 2.1 with respect to such series of Notes.

An Event of Default with respect to any series of Notes would not necessarily constitute an Event of Default with respect to any other series of Notes.

SECTION 7.2. Acceleration. If an Event of Default arising under Section 7.1(4) occurs and is continuing with respect to the Notes of any series then outstanding, the principal of, premium, if any, accrued and unpaid interest, if any, and Additional Amounts, if any, on all outstanding Notes of such series shall become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee (upon request of Holders of at least 25% in principal amount of the Notes of such series subject to the Event of Default then outstanding) shall, by notice in writing to the Issuer, or the Holders of at least 25% in principal amount of the then outstanding Notes of such series may, by notice in writing to the Issuer and the Trustee, declare all Notes of such series to be due and payable, and any such notice shall specify the respective Event of Default and that such notice is a “notice of acceleration”, and the principal of, premium, if any, accrued and unpaid interest, if any, and Additional Amounts, if any, on all outstanding Notes of such series shall become immediately due and payable.

SECTION 7.3. Other Remedies. If an Event of Default occurs and is continuing with respect to the Notes of any series then outstanding, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or, premium, if any, interest or Additional Amounts, if any, on the Notes of such series subject to the Event of Default or to enforce the performance of any provision of such Notes or this Indenture.

40

SECTION 7.4. The Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes of any series may be prosecuted and enforced by the Trustee without the possession of any of the Notes of such series or the production thereof in any proceeding relating thereto.

SECTION 7.5. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.7, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Notes of any series is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent or subsequent assertion or employment of any other appropriate right or remedy.

SECTION 7.6. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Notes may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Notes.

SECTION 7.7. Waiver of Past Defaults. Subject to Section 10.2, at any time after a declaration of acceleration with respect to a series of Notes as described in Section 7.2, the Holders of at least a majority in aggregate principal amount of the outstanding Notes of such series by written notice to the Trustee, may, on behalf of the Holders of all the Notes of such series, waive any existing Default or Event of Default (except with respect to a continuing Default or Event of Default in the payment of principal, premium, interest, Additional Amounts, if any, and other monetary obligations on such Notes) and rescind and annul a declaration of acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, interest, Additional Amounts, if any, and other monetary obligations on such Notes that have become due solely by such declaration of acceleration have been cured or waived and (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. Such waiver shall not excuse a continuing Default or Event of Default in the payment of principal of, premium and Additional Amounts, if any, and interest on such Notes held by a non-consenting Holder, or in respect of a covenant or a provision which cannot be amended or modified without the consent of each Holder affected. The Issuer shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of Holders of the applicable series of Notes has consented to such waiver and attaching copies of such consents. When a Default or Event of Default is waived with respect to a series of Notes, it is cured and ceases with respect to such Notes.

SECTION 7.8. Control by Majority. Subject to Section 2.14, the Holders of not less than a majority in principal amount of the outstanding Notes of a series may, by written notice to the Trustee, direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it with respect to the Notes of such series. Subject to Section 8.1, however, the Trustee may refuse to follow any direction that conflicts with any law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of another Holder of the Notes of such series, or that would involve the Trustee in liability or expense; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action under this Indenture, the Trustee will be entitled to indemnification or security to its satisfaction against all losses, liabilities, costs and expenses incurred by it in taking or not taking such action.

41

SECTION 7.9. Limitation on Suits. Except to enforce the right to receive payment of principal, premium, if any, interest when due and Additional Amounts, if any, no Holder may pursue any remedy with respect to this Indenture or the Notes of any series, unless:

(1)           such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2)           Holders of at least 25% in principal amount of the outstanding Notes of such series have requested the Trustee to pursue the remedy;

(3)           such Holders have offered the Trustee indemnity or security to its satisfaction against any loss, liability or expense;

(4)           the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of such security or indemnity; and

(5)           the Holders of a majority in principal amount of the outstanding Notes of such series have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

SECTION 7.10. Collection Suit by Trustee. If an Event of Default in the payment of principal, premium, if any, interest or Additional Amounts, if any, specified in clause (1) or clause (2) of Section 7.1 occurs and is continuing with respect to the Notes of any series, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Notes of such series for the whole amount of principal and accrued interest remaining unpaid and Additional Amounts, if any, thereon and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.6.

TRUSTEE

SECTION 8.1. Duties of Trustee.

Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under this Indenture at the request of any of the Holders of Notes of such series unless they shall have offered to the Trustee indemnity or security to its satisfaction against any loss, liability, cost or expense.

(b)           Except during the continuance of an Event of Default with respect to any series of Notes of which a Trust Officer of the Trustee has received written notice:

(1)            The Trustee and the Agents will perform only those duties as are specifically set forth herein and no others and no implied covenants or obligations shall be read into this Indenture against the Trustee or the Agents.

However, in the case of any such certificates or opinions which by any provision hereof are required to be furnished to the Trustee or the Agents, the Trustee or the Agents, as applicable, shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(c)            The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own fraud or willful misconduct, except that:

(1)            This paragraph does not limit the effect of subsection (b) of this Section 8.1.

(2)            Neither the Trustee nor any Agent shall be liable for any error of judgment made in good faith by a Trust Officer of such Trustee or Agent, unless it is proved that the Trustee or such Agent was negligent in ascertaining the pertinent facts.

(e)           Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to subsections (a), (b), (c) and (d) of this Section 8.1.

(f)            Neither the Trustee nor the Agents shall be liable for interest on any money received by them except as the Trustee and any Agent may agree in writing with the Issuer.

(g)           Any provision hereof relating to the conduct or affecting the liability of or affording protection to the Trustee or any Agent shall be subject to the provisions of this Section 8.1.

(h)           The rights, privileges, protections, immunities and benefits given to the Trustee, including its rights to be indemnified, are extended to, and shall be enforceable by the Trustee in each of its capacities in which it may serve, and to each Agent, custodian and other person employed to act hereunder.

(a)           The Trustee and each Agent may rely conclusively on and shall be protected from acting or refraining from acting based upon any document believed by them to be genuine and to have been signed or presented by the proper Person. Neither the Trustee nor any Agent shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent order, approval, appraisal, bond, debenture, note, coupon, security or other paper or document, but the Trustee or its Agents, as the case may be, in its discretion, may make reasonable further inquiry or investigation into such facts or matters stated in such document and if the Trustee or its Agents, as the case may be, shall determine to make such further inquiry or investigation, they shall be entitled to examine the books, records and premises of the Issuer, at reasonable times during normal business hours, personally or by agent or attorney. The Trustee shall not be deemed to have notice or any knowledge of any matter (including Defaults or Events of Default) unless a Trust Officer assigned to and working in the Trustee’s Trust & Security Services office has actual knowledge thereof or unless written notice thereof is received by the Trustee, Attention: Trust & Agency Services and such notice references the Notes of the applicable series generally, the Issuer or this Indenture.

(e)           The Trustee shall not be liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within its rights or powers conferred upon it by this Indenture; provided, however, that the Trustee’s conduct does not constitute willful misconduct, negligence or fraud.

(f)            The Trustee or any Agent may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

SECTION 8.3. Individual Rights of Trustee. The Trustee or any Agent in its respective individual or any other capacity may become the owner or pledgee of the Notes of any series and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not the Trustee or an Agent. However, in the event that the Trustee acquires any conflicting interest within the meaning of Section 310(b)(1) of the TIA, it must eliminate such conflict within 90 days or resign; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any indenture or indentures under which other securities or certificates of interest of participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met, other than the fact that such indentures are not described herein. Any Agent may do the same with like rights. The Trustee must comply with Sections 8.9 and 8.10.

SECTION 8.4. Trustee’s Disclaimer. The Trustee and the Agents shall not be responsible for and make no representation as to the validity, effectiveness, correctness or adequacy of this Indenture, any series of Notes, any Guarantee or any offering materials related to this Indenture or any series of Notes; it shall not be accountable for the Issuer’s use of the proceeds from the Notes of any series or any money paid to the Issuer or upon the Issuer’s direction under any provision hereof; it shall not be responsible for the use or application of any money received by any Agent and it shall not be responsible for any statement or recital herein of the Issuer, or any document issued in connection with the sale of the Notes of any series or any statement in the Notes of any series other than the Trustee’s certificate of authentication.

46

SECTION 8.5. Notice of Default. If an Event of Default with respect to the Notes of any series occurs and is continuing and a Trust Officer of the Trustee has received written notice of such event, the Trustee shall mail to each Holder of the Notes of such series, as their names and addresses appear in the Register, notice of the uncured Default or Event of Default within 60 days after the Trustee receives such notice. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, interest or Additional Amounts, if any, on any Note, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interest of the Holders of the Notes of such series.

SECTION 8.6. Compensation and Indemnity. The Issuer shall pay to the Trustee and the Agents from time to time such reasonable compensation as the Issuer and the Trustee shall from time to time agree upon in writing for its acceptance of this Indenture and services hereunder. The Trustee’s and the Agents’ compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee and the Agents upon request for all reasonable disbursements, expenses and advances (including reasonable fees and expenses of counsel) incurred or made by it in addition to the compensation for their services, except any such disbursements, expenses and advances as may be attributable to the Trustee’s or any Agent’s negligence, willful misconduct or fraud. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s and Agents’ accountants, experts and counsel and any taxes or other expenses incurred by a trust created pursuant to Section 9.4 hereof.

The Issuer agrees to pay the reasonable fees and expenses of the Trustee’s legal counsel in connection with its review, preparation and delivery of this Indenture and related documentation.

The Issuer shall indemnify each of the Trustee, any predecessor Trustee and the Agents (which, for purposes of this paragraph, include such Trustee’s and Agents’ Affiliates, officers, directors, employees and agents) and in any other capacity the Trustee may serve hereunder for, and hold them harmless against, any and all loss, damage, claim, expense or liability including taxes (other than taxes based on the income of the Trustee) incurred by the Trustee or an Agent without negligence, willful misconduct or fraud on its part, as determined by a court of competent jurisdiction in a final non-appealable decision in connection with acceptance of administration of this trust and performance of its duties under this Indenture, including the reasonable expenses and attorneys’ fees and expenses of defending itself against any claim of liability arising hereunder. The Trustee and the Agents shall notify the Issuer promptly of any claim asserted against the Trustee or such Agent for which they may seek indemnity. However, the failure by the Trustee or an Agent to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Issuer may defend the claim and the Trustee or such Agent shall cooperate in the defense (and may employ its own counsel reasonably satisfactory to the Trustee) at the Issuer’s expense. The Trustee or such Agent may have separate counsel and the Issuer shall pay the reasonable fees and expenses of such counsel. The Issuer need not pay for any settlement made without its written consent, which consent shall not be unreasonably withheld.

To secure the Issuer’s payment obligations in this Section 8.6, the Trustee and the Agents shall have a senior Lien prior to the Notes of each series against all money or property held or collected by the Trustee and the Agents, in their respective capacities as Trustee or Agents, except money or property held in trust to pay principal or premium, if any, Additional Amounts, if any, or interest on the Notes of any series.

47

The Issuer’s obligations under this Section 8.6 and any claim arising hereunder shall survive the termination of this Indenture, the resignation or removal of any Trustee or Agent, the discharge of the Issuer’s obligations pursuant to Article IX and any rejection or termination under any Bankruptcy Law.

SECTION 8.7. Replacement of Trustee. The Trustee and any Agent may resign at any time upon 30 days’ prior written notice to the Issuer. The Holders of a majority in principal amount of the outstanding Notes of any series may remove the Trustee or any Agent with respect to such series by so notifying the Issuer and the Trustee or such Agent, as the case may be, in writing and may appoint a successor trustee or agent with respect to such series with the Issuer’s consent. A resignation or removal of the Trustee or any Agent and the appointment of a successor Trustee or Agent, as the case may be, shall become effective only upon the successor Trustee’s or Agent’s acceptance of appointment, as the case may be, as provided in this Section 8.7. The Issuer may remove the Trustee or an Agent if:

(1)           the Trustee or the Agent, as the case may be, fails to comply with Section 8.9;

(2)           the Trustee or the Agent, as the case may be, is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee or the Agent, as the case may be, under any Bankruptcy Law;

(3)           a receiver or other public officer takes charge of the Trustee or the Agent, as the case may be, or its respective property; or

(4)           the Trustee or the Agent, as the case may be, becomes incapable of acting with respect to its duties hereunder.

If the Trustee or an Agent resigns or is removed or if a vacancy exists in the office of Trustee or Agent for any reason, the Issuer shall notify each Holder of the applicable series of Notes of such event and shall promptly appoint a successor Trustee or Agent, as the case may be. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes of such series may, with the Issuer’s consent, appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

A successor Trustee or Agent, as the case may be, shall deliver a written acceptance of its appointment to the retiring Trustee or Agent and to the Issuer. Immediately thereafter, the retiring Trustee or Agent, as the case may be, shall transfer, after payment of all sums then owing to the Trustee or Agent, as the case may be, pursuant to Section 8.6, all property held by it as Trustee or Agent to the successor Trustee or Agent, subject to the Lien provided in Section 8.6, the resignation or removal of the retiring Trustee or Agent, as the case may be, shall become effective, and the successor Trustee or Agent, as the case may be, shall have all the rights, powers and duties of the Trustee or Agent under this Indenture. A successor Trustee or Agent shall mail notice of its succession to each Holder of the applicable series of Notes.

48

If a successor Trustee or Agent does not take office within 60 days after the retiring Trustee or Agent resigns or is removed, (i) the retiring Trustee or Agent (as the case may be), the Issuer or the Holders of at least 10% in principal amount of the then outstanding Notes of the applicable series may petition any court of competent jurisdiction for the appointment of a successor Trustee or Agent or (ii) the retiring Trustee or Agent may appoint a successor Trustee or Agent, as applicable, at any time prior to the date on which a successor Trustee or Agent takes office; provided that such appointment shall be reasonably satisfactory to the Issuer.

If the Trustee or any Agent, after written request by any Holder of the applicable series of Notes who has been a Holder for at least six months, fails to comply with Section 8.9, such Holder may petition any court of competent jurisdiction for the removal of the Trustee or Agent, as the case may be, and the appointment of a successor thereto.

Notwithstanding replacement of the Trustee or any Agent pursuant to this Section 8.7, the Issuer’s obligations under Section 8.6 shall continue for the benefit of the retiring Trustee or Agent, as the case may be, and the Issuer shall pay to any replaced or removed Trustee or Agent all amounts owed under Section 8.6 upon such replacement or removal.

SECTION 8.8. Successor Trustee by Merger, etc. If the Trustee or any Agent consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to another corporation or banking association, the resulting, surviving or transferee corporation, without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee or Agent. In case Notes of any series shall have been authenticated, but not delivered, by the Trustee then in office, any successor by consolidation, merger or conversion to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes.

SECTION 8.9. Eligibility; Disqualification. There shall at all times be one (and only one) Trustee hereunder with respect to the Notes of each series, which may be Trustee hereunder for Notes of one or more other series. Each Trustee shall be a Person organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. The Trustee (together with its corporate parent) shall have a combined capital and surplus of at least $100.0 million as set forth in the most recent applicable published annual report of condition. The Trustee shall not be deemed to have a conflict of interest under or in respect of its duties under this Indenture except and to the extent provided for in Section 310(b)(1) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(1) of the TIA any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuer are outstanding if the requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met, other than the fact that such indentures are not described herein.

SECTION 8.10. Disqualification; Conflicting Interests. Within 90 days after becoming aware that a material conflict of interest exists between the Trustee’s role as a trustee and any other capacity, the Trustee shall either (i) eliminate such conflict of interest or (ii) resign from office; provided, however, that this Indenture, the Notes of any series and the Guarantees shall remain valid notwithstanding a material conflict of interest of the Trustee.

49

SECTION 8.11. Preferential Collection of Claims Against Issuer. The Trustee shall comply with Section 311(a) and 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein.

SECTION 8.12. Force Majeure. In no event shall the Trustee or any Agent, in each of its capacities hereunder, be liable for any failure or delay in the performance of its obligations under this Indenture because of circumstances beyond its control, including, but not limited to, acts of God, epidemics, pandemics, flood, war (whether declared or undeclared), terrorism, fire, riot, embargo and government action, including any laws, ordinances, regulations or the like which restrict or prohibit the providing of the services or the obligations contemplated by this Indenture.

SECTION 8.13. Consequential Loss. Notwithstanding anything to the contrary in this Indenture, in no event shall the Trustee or any Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee or such Agent has been advised of such loss or damage and regardless of the form of action.

(1)            the rights of Holders of outstanding Notes of such series to receive payments in respect of the principal of, premium, if any, interest and Additional Amounts, if any, on such Notes when such payments are due (including on a Redemption Date) from the trust created pursuant to this Indenture;

50

(4)            this Article IX and the obligations set forth in Section 9.6 hereof.

Subject to compliance with this Article IX, the Issuer may exercise its option under Section 9.2 notwithstanding the prior exercise of its option under Section 9.3 with respect to the Notes of any series.

SECTION 9.3. Covenant Defeasance. Upon the Issuer’s exercise under Section 9.1 of the option applicable to this Section 9.3 with respect to the Notes of any series, (a) the Issuer and the Guarantors shall be released from their obligations under Sections 4.4, 4.6 and 6.1 and any covenants provided pursuant to Section 2.1(23), 10.1(b) or 10.1(g) for the benefit of the Holders of such Notes and (b) the occurrence of any event specified in Sections 7.1(3) (insofar as it relates to Sections 4.4, 4.6 and 6.1 and any covenants provided pursuant to Section 2.1(23), 10.1(b) or 10.1(g)) or 7.1(5) shall be deemed not to be or result in an Event of Default, in each case with respect to such Notes as provided in this Section on and after the date the conditions set forth in Section 9.4 are satisfied (hereinafter, “Covenant Defeasance”) and the Notes of such series shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes).

For the purposes hereof, such Covenant Defeasance means that, (i) with respect to the outstanding Notes of the applicable series, the Issuer and the Guarantors may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant with respect to such Notes, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and (ii) payment on such Notes may not be accelerated because of an Event of Default specified in Sections 7.1(3) (insofar as it relates to Sections 4.4, 4.6 and 6.1 and any covenants provided pursuant to Section 2.1(23), 10.1(b) or 10.1(g)) or 7.1(5).

SECTION 9.4. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to the application of either Section 9.2 or Section 9.3 to any series of Notes:

Upon the request of the Issuer, accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 10.5, the Trustee shall join with the Issuer and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations which may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture which adversely affects its own rights, duties or immunities hereunder or otherwise.

56

SECTION 10.2. With Consent of Holders of Notes. The Issuer, the applicable Guarantors and the Trustee may amend or supplement this Indenture, any series of Notes or the Guarantees with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding affected by such amendment or supplement (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes), and, subject to Section 7.7, any existing Default, an Event of Default or its consequences or compliance with any provision of this Indenture, such series of Notes or the Guarantees may be waived with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding affected by such waiver (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Notes). However, without the consent of each Holder affected, an amendment or waiver may not, with respect to any Notes held by a non-consenting Holder:

(a)            reduce the principal amount of such Notes whose Holders must consent to an amendment, supplement or waiver;

(b)            reduce the principal of or change the fixed maturity of such Notes;

(c)            reduce the rate of or change the time for payment of interest on such Notes;

(d)            reduce the premium or amount payable upon the redemption of such Note or change the time at which such Notes may be redeemed as described in paragraphs 7 and 8 of such Notes;

(e)            waive a Default or Event of Default in the payment of principal of, or interest, premium or Additional Amounts, if any, on such Notes (except a rescission of acceleration of such Notes by the Holders of at least a majority in aggregate principal amount of such Notes and a waiver of the payment default that resulted from such acceleration);

(f)            make any Note payable in money other than that stated in such Notes;

(g)            make any change in the provisions of this Indenture relating to the rights of any Holder to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes or any Guarantee in respect thereof;

(h)           waive a redemption payment with respect to such Notes;

(i)            make any change in the provisions of this Indenture described in Section 4.7 hereof and paragraph 2 of such Notes that adversely affects the rights of any Holder of such Notes or amends the terms of such Notes in a way that would result in a loss of an exemption from any of the Taxes described thereunder or an exemption from any obligation to withhold or deduct Taxes so described thereunder unless the Payor agrees to pay Additional Amounts, if any, in respect thereof;

(j)            make any change in the preceding amendment and waiver provisions; or

(k)            if such Notes are convertible into or for any other securities or property of the Issuer, make any change that adversely affects in any material respect the right to convert any Note of such series (except as permitted by Section 10.1) or decrease the conversion rate or increase the conversion price of any such Note of such series, unless such decrease or increase is permitted by the terms of such Note.

57

Upon the request of the Issuer, accompanied by a Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence reasonably satisfactory to the Trustee of the consent of the Holders of Notes of the applicable series as aforesaid, and upon receipt by the Trustee of the documents described in Section 10.5, the Trustee shall join with the Issuer and the applicable Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture adversely affects the Trustee’s own rights, duties or immunities hereunder or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. It shall not be necessary for the consent of the Holders of the applicable series of Notes under this Section 10.2 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section becomes effective, the Issuer shall mail to the Holders of the applicable series of Notes a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

SECTION 10.3. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder of a Note.

SECTION 10.4. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer, in exchange for all Notes of a series, may issue and the Trustee shall authenticate new Notes of such series that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 10.5. Trustee to Sign Amendments, etc. The Trustee shall, at the cost and expense of the Issuer, execute any amendment, supplement or waiver authorized pursuant to this Article X; provided, however, that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which adversely affects the Trustee’s own rights, duties or immunities under this Indenture. The Trustee shall be entitled to receive indemnity reasonably satisfactory to it, and shall be fully protected in relying upon, an Opinion of Counsel and an Officers’ Certificate each stating that (i) the execution of any amendment, supplement or waiver authorized pursuant to this Article X is authorized or permitted by this Indenture and (ii) subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws affecting the rights of creditors generally and to the principles of equity, whether considered in a proceeding at law or in equity, constitutes the legal, valid and binding obligations of the Issuer enforceable in accordance with its terms; provided that the Trustee may, in its sole discretion, waive the requirement of an Opinion of Counsel with respect to clause (i).

ARTICLE XI

GUARANTEES

SECTION 11.1. Guarantee. (a)  Subject to the provisions of Section 11.2 hereof and any other limitations under applicable law, each Guarantor (which for the avoidance of doubt, shall include (i) Smurfit Westrock, if either SKT or SWF is the Issuer, (ii) SKT, if either Smurfit Westrock or SWF is the Issuer, and (ii) SWF, if either Smurfit Westrock or SKT is the Issuer) hereby fully, unconditionally and irrevocably guarantees, as primary obligor and not merely as surety, jointly and severally with each other Guarantor, to each Holder of the Notes issued pursuant to this Indenture and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, interest and Additional Amounts, if any, on the Notes and all other obligations of the Issuer under this Indenture and the Notes (all the foregoing being hereinafter collectively called the “Guarantee Obligations”). Each Guarantor further agrees (to the extent permitted by and subject to requirements under applicable law) that the Guarantee Obligations may be extended or renewed, in whole or in part, without notice or further assent from it, and that it shall remain bound under this Article XI (to the extent permitted by and subject to requirements under applicable law), notwithstanding any extension or renewal of any Guarantee Obligation.

(b)            To the extent permitted by law, each Guarantor waives presentation to, demand of, payment from and protest to the Issuer of any of the Guarantee Obligations and also waives notice of protest for nonpayment, including, for the avoidance of doubt, any right of subrogation in relation to the Holders in respect of any such Guarantee Obligations. Each Guarantor waives notice of any default under the Notes or the Guarantee Obligations. The obligations of each Guarantor hereunder shall not (to the extent permitted by and subject to requirements under applicable law) be affected by: (i) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Issuer, any other Guarantor or any other person under this Indenture, the Notes or any other agreement or otherwise; (ii) any extension or renewal of any thereof; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the Notes or any other agreement; (iv) the release of any security held by any Holder or the Trustee for the Guarantee Obligations or any of them; or (v) any change in the ownership of the Issuer.

(c)            Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Guarantee Obligations.

(d)            Subject to the provisions of Section 11.2 hereof, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Guarantee Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not (to the extent permitted by law) be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guarantee Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not (to the extent permitted by law) be discharged or impaired or otherwise affected by (i) the failure of any Holder to assert any claim or demand or to enforce any remedy under this Indenture, the Notes or any other agreement; (ii) any waiver or modification of any thereof; (iii) any default, failure or delay, willful or otherwise, in the performance of the Guarantee Obligations; or (iv) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

59

(e)            Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of, premium, if any, interest or Additional Amounts, if any, on any of the Guarantee Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization (including examinership) of the Issuer or otherwise.

(f)            Subject to the provisions of Section 11.2 hereof, in furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay any of the Guarantee Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, each Guarantor hereby promises to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee for and on behalf of itself and the Holders an amount equal to the sum of (i) the unpaid amount of such Guarantee Obligations then due and owing and (ii) accrued and unpaid interest on such Guarantee Obligations then due and owing (but only to the extent not prohibited by law). Payments made under the Guarantees shall be made to the Trustee on behalf of the Holders.

(g)            Each Guarantor further agrees that, as between it, on the one hand, and the Holders, on the other hand, but subject always to Section 11.2 hereof, (x) the maturity of the Guarantee Obligations guaranteed hereby may be accelerated as provided in this Indenture for the purposes of its Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Guarantee Obligations, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purposes of its Guarantee.

(h)            Each Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 11.1.

(i)            Neither the Issuer nor the Guarantors shall be required to make a notation on the Notes of any series to reflect any Guarantee or any release, termination or discharge thereof.

SECTION 11.2. Limitation on Liability. (a)  Any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guarantee Obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or transfer, voidable preference, financial assistance, corporate purpose, capital maintenance or similar laws, regulations or defenses affecting the rights of creditors generally or other considerations under applicable law.

60

(b)            The liability of each Guarantor under this Article XI shall be limited to the extent of the limitations (if any) set out in any supplemental indenture executed by a Subsidiary providing for a Guarantee.

SECTION 11.3. Successors and Assigns. This Article XI shall be binding upon each Guarantor and its successors and assigns and shall enure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred upon that party in this Indenture and in the Notes of the applicable series shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Indenture.

SECTION 11.4. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article XI shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article XI at law, in equity, by statute or otherwise.

SECTION 11.5. Modification. No modification, amendment or waiver of any provision of this Article XI, nor the consent to any departure by any Guarantor therefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

SECTION 11.6. Release of Guarantor. The Guarantee of a Guarantor will be released with respect to the Notes:

(1)            in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) Smurfit Westrock or a Subsidiary of Smurfit Westrock;

(2)            in connection with any sale or other disposition of Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) Smurfit Westrock or a Subsidiary of Smurfit Westrock, if the Guarantor ceases to be a Subsidiary of Smurfit Westrock as a result of the sale or other disposition;

(3)            upon the release or discharge of the guarantee or other obligation of such Guarantor under the Revolving Facility Agreement, or such other guarantee or other obligation that resulted in the creation of such Guarantee, except a release or discharge by or as a result of payment under such guarantee; provided that the guarantee of such Guarantor under the Existing Notes has been released or is concurrently released;

61

(4)            by written notice from the Issuer to the Trustee if such Guarantor does not then guarantee any obligations under any of the Existing Notes (after giving effect to Indebtedness and guarantees concurrently being released or repaid);

(5)            in accordance with Article IX;

(6)            upon the full and final payment and performance of all obligations of the Issuer and the Guarantors under this Indenture and the Notes;

(8)            by written notice from the Issuer to the Trustee so long as the Notes have an Investment Grade rating from two or more Rating Agencies; provided that none of the Existing Notes are guaranteed by such Guarantor (after giving effect to guarantees concurrently being released) and no Default or Event of Default shall have occurred and be continuing at the time of such written notice,

*provided, however,*that, notwithstanding the above, any Guarantee by Smurfit Westrock may only be released to the extent that the Ultimate Parent has provided a Guarantee of the Notes (other than any release pursuant to clauses (5), (6) and (7) above).

At the request of the Issuer, the Trustee shall execute and deliver an appropriate instrument evidencing such release.

SECTION 12.2. Notice to Holders; Waiver.

Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at its address as it appears in the Register, or by electronic transmission, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice when mailed to a Holder in the aforesaid manner shall be conclusively deemed to have been received by such Holder whether or not actually received by such Holder. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Where this Indenture provides for notice of any event to a Holder of a Global Note, such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to the applicable procedures of the Depositary, not later than the latest date, if any, and not earlier than the earliest date, if any, prescribed for the giving of such notice.

63

SECTION 12.3. Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Issuer to the Trustee or an Agent to take any action under this Indenture, the Issuer shall furnish to the Trustee at the request of the Trustee such certificates and opinions as may be required under the TIA; provided, however, that no Opinion of Counsel shall be required in connection with (i) the issuance of Notes that are part of any series as to which such an opinion required under the TIA has been furnished, (ii) a request by the Issuer that the Trustee deliver a notice to Holders under this Indenture where the Trustee receives an Officers’ Certificate with respect to such notice, or (iii) a cancellation order delivered pursuant to Section 2.10. Each such certificate and opinion shall be given in the form of an Officers’ Certificate, if to be given by an Officer of the Issuer, and an Opinion of Counsel, if to be given by counsel, and shall comply with the requirements of the TIA and any other requirements set forth in this Indenture.

In any case where several matters are required to be certified by, or covered by an Opinion of Counsel of, any specified Person, it is not necessary that all such matters be certified by, or covered by the Opinion of Counsel of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an Opinion of Counsel with respect to some matters and one or more such Persons as to other matters, and any such Person may certify or give an Opinion of Counsel as to such matters in one or several documents.

Any certificate of an Officer of the Issuer may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such Officer knows, or in the exercise of reasonable care should know, that such Opinion of Counsel with respect to the matters upon which his or her certificate is based are erroneous. Any Opinion of Counsel may be based, and may state that it is so based, insofar as it relates to factual matters, upon a certificate of, or representations by, an Officer or Officers of the Issuer stating that the information with respect to such factual matters is in the possession of the Issuer, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

SECTION 12.4. Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include:

(1)            a statement that the Person making such certificate or opinion has read such covenant or condition;

(2)            a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3)            a statement that, in the opinion of such Person, such Person has made such examination or investigation as is necessary to enable such Person to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(4)            a statement as to whether or not, in the opinion of each such Person, such condition or covenant has been complied with, provided, however, that an issuer of an Opinion of Counsel may reasonably rely as to any matter of fact on an Officers’ Certificate or a certificate of a public official.

64

SECTION 12.5. Acts of Holders; Record Dates.

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 8.1) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section.

Without limiting the generality of the foregoing, a Holder, including a Depositary that is a Holder of a Global Note, may make, give or take, by a proxy or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and a Depositary that is a Holder of a Global Note may provide its proxy or proxies to the Beneficial Owners of interests in any such Global Note.

The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

The ownership, principal amount and serial numbers of Notes held by any Person, and the date of commencement of such Person’s holding the same, shall be proved by the Register.

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Note.

65

The Issuer may set any day as a record date for the purpose of determining the Holders of outstanding Notes of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Notes of such series, but the Issuer shall have no obligation to do so; provided that the Issuer may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of outstanding Notes of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of outstanding Notes of such series on such record date. Nothing in this paragraph shall be construed to prevent the Issuer from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of outstanding Notes of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Issuer, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Notes of the relevant series in the manner set forth in Section 12.1 or Section 12.2.

The Trustee may set any day as a record date for the purpose of determining the Holders of outstanding Notes of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 7.2, (iii) any request to institute proceedings referred to in Section 7.9 or (iv) any direction referred to in Section 7.8, in each case with respect to Notes of such series. If any record date is set pursuant to this paragraph, the Holders of outstanding Notes of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of outstanding Notes of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of outstanding Notes of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Issuer’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Issuer in writing and to each Holder of Notes of the relevant series in the manner set forth in Section 12.1 or Section 12.2.

With respect to any record date set pursuant to this Section, the party hereto which sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Notes of the relevant series in the manner set forth in Section 12.2, on or prior to the then existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day following such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day following the applicable record date.

66

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

SECTION 12.6. Legal Holidays. If a payment date is not a Business Day, payment may be made on the next succeeding day that is a Business Day, and no interest shall accrue for the intervening period.

SECTION 12.7. Governing Law. Each of this Indenture, the Notes of any series and the Guarantees, and the rights and duties of the parties hereunder and thereunder, shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 12.8. Submission to Jurisdiction; Appointment of Agent for Service. To the fullest extent permitted by applicable law, the Issuer and each Guarantor irrevocably submits to the non-exclusive jurisdiction of and venue in any federal or state court in the Borough of Manhattan in the City of New York, County and State of New York, United States of America, in any suit or proceeding based on or arising out of or under or in connection with this Indenture or any of the transactions contemplated hereby, and irrevocably agrees that all claims in respect of such suit or proceeding may be determined in any such court. The Issuer and each Guarantor, to the fullest extent permitted by applicable law, irrevocably and fully waive the defense of an inconvenient forum to the maintenance of such suit or proceeding and hereby irrevocably designate and appoint Smurfit WestRock US Holdings Corporation (the “Authorized Agent”) as its authorized agent upon whom process may be served in any such suit or proceeding. The Issuer and each Guarantor represent and warrant that the Authorized Agent has accepted such appointment and irrevocably agreed to act as said agent for service of process. The Issuer and each Guarantor agree that service of process upon its Authorized Agent and written notice of said service to the Issuer or a Guarantor, mailed by first class mail or delivered to its Authorized Agent shall be deemed in every respect effective service of process upon the Issuer or such Guarantor, respectively, in any such suit or proceeding. Nothing herein shall affect the right of any person to serve process in any other manner permitted by law. The Issuer agrees that a final action in any such suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other lawful manner. Notwithstanding the foregoing, any action against the Issuer arising out of or based on this Indenture or the transactions contemplated hereby may also be instituted in any competent court in Ireland and the Issuer expressly accepts the jurisdiction of any such court in any such action. The Issuer hereby irrevocably waives, to the extent permitted by law, any immunity to jurisdiction to which it may otherwise be entitled (including immunity to pre-judgment attachment, post-judgment attachment and execution) in any legal suit, action or proceeding against it arising out of or based on this Indenture, the Notes or the transactions contemplated hereby. Each party to this Indenture waives, to the fullest extent permitted by applicable law, any right that it may have to a trial by jury in respect of any proceeding arising out of or relating to this Indenture, the Notes or the transactions contemplated hereby. The provisions of this Section 12.8 are intended to be effective upon the execution of this Indenture and the Notes of any series without any further action by the Issuer, any Guarantor or the Trustee and the introduction of a true copy of this Indenture into evidence shall be conclusive and final evidence as to such matters.

67

SECTION 12.9. No Personal Liability of Directors, Officers, Employees, Incorporators or Stockholders. No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the Notes of any series, the Guarantees or this Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.

SECTION 12.10. Currency Calculation. Except as otherwise specifically set forth herein, for purposes of determining compliance with any Dollar-denominated restriction herein, the Dollar-equivalent amount for purposes hereof that is denominated in a Non-Dollar Currency shall be calculated based on the relevant currency exchange rate in effect on the date such Non-Dollar Currency amount is incurred or made, as the case may be. The Trustee or Paying Agent shall have no obligation or responsibility to calculate or confirm such calculation.

SECTION 12.11. Successors. All agreements of the Issuer and the Guarantors in this Indenture, the Notes of any series and the Guarantees shall bind their respective successors. All agreements of the Trustee in this Indenture shall bind its successor.

SECTION 12.12. Counterpart Originals. All parties hereto may sign any number of copies of this Indenture. Each signed copy or counterpart shall be an original, but all of them together shall represent one and the same agreement. Facsimile, documents executed, scanned and transmitted electronically and electronic signatures, including those created or transmitted through a software platform or application, shall be deemed original signatures for purposes of this Indenture and all other related documents and all matters and agreements related thereto, with such facsimile, scanned and electronic signatures having the same legal effect as original signatures. The parties agree that this Indenture or any other related document or any instrument, agreement or document necessary for the consummation of the transactions contemplated by this Indenture or other documents related hereto or thereto (including, without limitation, addendums, amendments, notices, instructions, communications with respect to the delivery of securities or the wire transfer of funds or other communications) (“Executed Documentation”) may be accepted, executed or agreed to through the use of an electronic signature in accordance with applicable laws, rules and regulations in effect from time to time applicable to the effectiveness and enforceability of electronic signatures. Any Executed Documentation accepted, executed or agreed to in conformity with such laws, rules and regulations will be binding on all parties hereto to the same extent as if it were physically executed and each party hereby consents to the use of any third party electronic signature capture service providers as may be reasonably chosen by a signatory hereto or thereto. When the Trustee acts on any Executed Documentation sent by electronic transmission, the Trustee will not be responsible or liable for any losses, costs or expenses arising directly or indirectly from its reliance upon and compliance with such Executed Documentation, notwithstanding that such Executed Documentation (a) may not be an authorized or authentic communication of the party involved or in the form such party sent or intended to send (whether due to fraud, distortion or otherwise) or (b) may conflict with, or be inconsistent with, a subsequent written instruction or communication; it being understood and agreed that the Trustee shall conclusively presume that Executed Documentation that purports to have been sent by an authorized officer of a Person has been sent by an authorized officer of such Person. The party providing Executed Documentation through electronic transmission or otherwise with electronic signatures agrees to assume all risks arising out of such electronic methods, including, without limitation, the risk of the Trustee acting on unauthorized instructions and the risk of interception and misuse by third parties.

68

SECTION 12.13. Severability. In case any one or more of the provisions in this Indenture or in the Notes of any series shall be held invalid, illegal or unenforceable, in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions shall not in any way be affected or impaired thereby, it being intended that all of the provisions hereof shall be enforceable to the full extent permitted by law.

SECTION 12.14. Table of Contents, Headings, etc. The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

SECTION 12.15. Patriot Act. In order to comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including, without limitation, those relating to the funding of terrorist activities and money laundering, including Section 326 of the USA PATRIOT Act of the United States (“Applicable Law”), the Trustee is required to obtain, verify, record and update certain information relating to individuals and entities which maintain a business relationship with the Trustee. Accordingly, each of the parties agree to provide to the Trustee, upon their request from time to time such identifying information and documentation as may be available for such party in order to enable the Trustee to comply with Applicable Law.

1. Interest. [INSERT NAME OF APPLICABLE ISSUER], a [·] company incorporated under the laws of [·] and having its registered office at [·] (the “Issuer”), promises to pay interest on the principal amount of this Note at the rate and in the manner specified below. Interest on the Notes will be payable [semi-annually] in arrears on [·] [·] and [·] [·] of each year, commencing [·], [·]. The Issuer will make each interest payment to the Holders of record at the close of business on the immediately preceding [·] [·] and [·] [·] of each year. Rights of holders of beneficial interests to receive such payments will be subject to applicable procedures of DTC. Interest on the Notes will accrue at the rate of [[·]% per annum] on the aggregate nominal amount of the Notes outstanding. Interest accruing on all Notes then outstanding shall be payable in cash. Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a [360-day year consisting of twelve 30-day months].

Any interest paid on this Note shall be increased to the extent necessary to pay Additional Amounts as set forth herein.

2. Additional Amounts. All payments made by the Payor on the Notes or any Guarantor with respect to its Guarantee will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) imposed or levied by or on behalf of (1) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (2) any jurisdiction from or through which payment on the Notes or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (1) and (2), a “Relevant Taxing Jurisdiction”), unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes of any Relevant Taxing Jurisdiction shall at any time be required from any payments made with respect to the Notes or the Guarantees, including, without limitation, payments of principal, Redemption Price, interest or premium, if any, the Payor or the relevant Guarantor, as applicable, will pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by the Holders of the Notes or the Trustee, as the case may be, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), equal the amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no such Additional Amounts will be payable with respect to:

(1)  any Taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction upon any payments to a Holder or Beneficial Owner who is liable for such Taxes in respect of the Notes by reason of the Holder (or a fiduciary, settlor, beneficiary, member, partner or shareholder of, or possessor of power over the relevant Holder, if the relevant Holder is an estate, nominee, trust, partnership, limited liability company or corporation) or Beneficial Owner having any present or former connection with such Relevant Taxing Jurisdiction (including, without limitation, being resident for tax purposes, being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Relevant Taxing Jurisdiction) other than a connection arising from the acquisition, ownership or holding of such Note or enforcement of rights thereunder or the receipt of payments in respect of the Notes or with respect to any Guarantee;

A-1

(2)  any Taxes that would not have been imposed if the Holder or Beneficial Owner had made a declaration of non-residence or any other claim or filing for exemption to which it is entitled (provided that (x) such declaration of non-residence or other claim or filing for exemption is required by the applicable law of the applicable Relevant Taxing Jurisdiction as a precondition to exemption from the requirement to deduct or withhold such Taxes and (y) at least 30 days prior to the first payment date with respect to which such declaration of non-residence or other claim or filing for exemption is required under the applicable law of the applicable Relevant Taxing Jurisdiction, the relevant Holder or Beneficial Owner at that time has been notified in writing by the Payor or any other person through whom payment may be made that a declaration of non-residence or other claim or filing for exemption is required to be made);

(3)  except in the case of the winding up of the Payor, any Note presented for payment (where presentation is required) in the Relevant Taxing Jurisdiction (unless by reason of the Payor’s actions, presentment could not have been made elsewhere and except to the extent that the Holder would have been entitled to Additional Amounts had the Notes been presented elsewhere);

(4)  any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented during such 30 day period);

This Note is one of a duly authorized issue of Notes of the Issuer designated as its [Insert Title of the Notes] (the “Notes”). The terms of the Notes include those stated in the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture for a statement of them. The Notes are senior obligations of the Issuer. Additional Notes may be issued from time to time under the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time.

Optional Redemption. Except as set forth below in this Paragraph 7 or under Paragraph 8, none of the Notes will be redeemable prior to [·], [·].

[Any optionalredemption provisions to be included.]

8. Special Tax Redemption. The Issuer may, at its option, redeem the Notes in whole, but not in part, at any time upon giving not less than 10 nor more than 60 days’ notice to the Holders of the Notes (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption (a “Tax Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if a Payor determines that, as a result of: (1) any change in, or amendment to, the law or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation or (2) any change in position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) (each of the foregoing in clauses (1) and (2), a “Change in Tax Law”), the Payor or any Guarantor is, or on the next interest payment date in respect of the Notes would be, required to pay Additional Amounts with respect to the Notes, and the Payor or the relevant Guarantor (as appropriate) cannot avoid such obligation by taking reasonable measures available to it. In the case of the Issuer or any Guarantor as of the original issue date of the Notes, the Change in Tax Law must become effective on or after the original issue date of the Notes. In the case of a Successor Issuer or any Person who becomes a Guarantor after the original issue date of the Notes or any successor of any Guarantor, the Change in Tax Law must become effective after the date that the Issuer first makes payment on the Notes or after the date on which such Person became a Guarantor or a successor of any Guarantor, as applicable. Notice of redemption for taxation reasons will be published in accordance with the procedures set forth in the Indenture. Notwithstanding the foregoing, no such notice of redemption will be given earlier than 90 days prior to the earliest date on which the Payor or Guarantor, as applicable, would be obligated to make such payment or withholding if a payment in respect of the Notes were then due. Prior to the publication or mailing of any notice of redemption of the Notes pursuant to the foregoing, the Payor will deliver to the Trustee an opinion of an independent tax counsel reasonably satisfactory to the Trustee to the effect that the circumstances referred to above exist. The Trustee will accept such opinion as sufficient existence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders of the Notes.

9. Guarantees. The payment by the Issuer of the principal of, premium, if any, interest and Additional Amounts, if any, on the Notes and all other obligations of the Issuer under the Indenture is, subject to Section 11.2 of the Indenture and limitations under applicable law, fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by each of the Guarantors to the extent set forth in the Indenture.

15. Successors. When a successor assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

16. Defaults and Remedies. Subject to certain restrictions, if an Event of Default (other than an Event of Default specified in clause (4) of Section 7.1 of the Base Indenture) occurs and is continuing with respect to the Notes, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, interest, and Additional Amounts, if any, including an accelerated payment) if it determines that withholding notice is in their interest.

17. Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

[INSERT TITLE OF THE NOTES]

1. Interest. [Insert name of applicable issuer], a [·] company incorporated under the laws of [·] and having its registered office at [·] (the “Issuer”), promises to pay interest on the principal amount of this Note at the rate and in the manner specified below. Interest on the Notes will be payable [semi-annually] in arrears on [·] [·] and [·] [·] of each year, commencing [·], [·]. The Issuer will make each interest payment to the Holders of record at the close of business on the immediately preceding [·] [·] and [·] [·] of each year. Rights of holders of beneficial interests to receive such payments will be subject to applicable procedures of DTC. Interest on the Notes will accrue at the rate of [[·]% per annum] on the aggregate nominal amount of the Notes outstanding. Interest accruing on all Notes then outstanding shall be payable in cash. Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a [360-day year consisting of twelve 30-day months].

Any interest paid on this Note shall be increased to the extent necessary to pay Additional Amounts as set forth herein.

2. Additional Amounts. All payments made by the Payor on the Notes or any Guarantor with respect to its Guarantee will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) imposed or levied by or on behalf of (1) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (2) any jurisdiction from or through which payment on the Notes or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (1) and (2), a “Relevant Taxing Jurisdiction”), unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes of any Relevant Taxing Jurisdiction shall at any time be required from any payments made with respect to the Notes or the Guarantees, including, without limitation, payments of principal, Redemption Price, interest or premium, if any, the Payor or the relevant Guarantor, as applicable, will pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by the Holders of the Notes or the Trustee, as the case may be, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), equal the amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no such Additional Amounts will be payable with respect to:

(1)  any Taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction upon any payments to a Holder or Beneficial Owner who is liable for such Taxes in respect of the Notes by reason of the Holder (or a fiduciary, settlor, beneficiary, member, partner or shareholder of, or possessor of power over the relevant Holder, if the relevant Holder is an estate, nominee, trust, partnership, limited liability company or corporation) or Beneficial Owner having any present or former connection with such Relevant Taxing Jurisdiction (including, without limitation, being resident for tax purposes, being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Relevant Taxing Jurisdiction) other than a connection arising from the acquisition, ownership or holding of such Note or enforcement of rights thereunder or the receipt of payments in respect of the Notes or with respect to any Guarantee;

(2)  any Taxes that would not have been imposed if the Holder or Beneficial Owner had made a declaration of non-residence or any other claim or filing for exemption to which it is entitled (provided that (x) such declaration of non-residence or other claim or filing for exemption is required by the applicable law of the applicable Relevant Taxing Jurisdiction as a precondition to exemption from the requirement to deduct or withhold such Taxes and (y) at least 30 days prior to the first payment date with respect to which such declaration of non-residence or other claim or filing for exemption is required under the applicable law of the applicable Relevant Taxing Jurisdiction, the relevant Holder or Beneficial Owner at that time has been notified in writing by the Payor or any other person through whom payment may be made that a declaration of non-residence or other claim or filing for exemption is required to be made);

(3)  except in the case of the winding up of the Payor, any Note presented for payment (where presentation is required) in the Relevant Taxing Jurisdiction (unless by reason of the Payor’s actions, presentment could not have been made elsewhere and except to the extent that the Holder would have been entitled to Additional Amounts had the Notes been presented elsewhere);

(4)  any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented during such 30 day period);

(5)  any Taxes that are payable otherwise than by withholding from a payment of the principal of, premium, if any, or interest, if any, on the Notes or with respect to any Guarantee;

(6)  any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or other governmental charge;

(7)  a Tax imposed in connection with a Note presented for payment by or on behalf of a Holder or Beneficial Owner who would have been able to avoid such Tax by presenting the Note to, or otherwise accept payment from, another paying agent in a member state of the European Union;

(8)  any Taxes imposed, deducted or withheld pursuant to Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code, in each case, as of the issue date (and any amended or successor version that is substantively comparable); any current or future regulations or agreements thereunder, official interpretations thereof or any law implementing an intergovernmental agreement relating thereto; or any treaty, law, regulation or other official guidance enacted in any other jurisdiction, facilitating implementation thereof;

(9)  all United States backup withholding taxes;

(10)  any Tax deducted, withheld or imposed in connection with the Dutch Withholding Tax Act 2021 (Wet bronbelasting 2021), as amended from time to time; or

(11) any combination of clauses (1) through (10) above.

Such Additional Amounts will also not be payable where, had the Beneficial Owner of the Note been the Holder of the Note, it would not have been entitled to payment of Additional Amounts by reason of clauses (1) to (11) inclusive above.

Upon request, the Issuer will provide the Trustee with documentation satisfactory to the Trustee evidencing the payment of Additional Amounts. Copies of such documentation will be made available to the Holders upon request.

3. Method of Payment. The Issuer shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders at the close of business on the Record Date with respect to such Notes immediately preceding the interest payment date for such interest. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay all amounts owing hereunder in [Dollars][Non-DollarCurrency]. With respect to payments in Dollars, if (i) a Holder has given wire transfer instructions to the Issuer and the Paying Agent in writing and (ii) the Paying Agent has received such written wire transfer instruction at least 15 days prior to the date of the relevant payment, then the Issuer will pay all interest, premium and Additional Amounts, if any, on that Holder’s Notes in accordance with those instructions by wire transfer of same day funds to the Paying Agent who in turn will wire such funds to the Holder hereof or to such other Person as the Holder hereof may in writing to the Paying Agent direct. In all other cases, the Issuer may elect to make payments of interest, premium and Additional Amounts, if any, on a Holder’s Notes by check mailed to the Holders at their addresses set forth in the register of Holders. Payments on Notes will be made through the office or agency of the Paying Agent and Registrar for the Notes unless the Issuer elects to make interest payments by check as previously described. If payments are made through the Paying Agent, immediately available funds for the payment of the principal of, premium, if any, interest and Additional Amounts, if any, on this Note due on any interest payment date, maturity date, Redemption Date or other repurchase date will be made available to the Paying Agent to permit the Paying Agent to pay such funds to the Holders on such respective dates.

4. Paying Agent, Registrar and Transfer Agent. Initially, Deutsche Bank Trust Company Americas will act as Paying Agent, Registrar and Transfer Agent. In the event that a Paying Agent or Transfer Agent is replaced, the Issuer will provide notice thereof as set forth in the Indenture. The Issuer may change any Registrar without notice to the Holders. The Issuer or any of its Subsidiaries may, subject to certain exceptions, act in any such capacity.

5. Indenture. The Issuer issued the Notes under an Indenture, dated as of November 21, 2025 (the “Base Indenture”), as supplemented by an Officers’ Certificate, dated [·], pursuant to Sections 2.1 and 12.4 of the Base Indenture (together with the Base Indenture, the “Indenture”), among the Issuer, the Guarantors and Deutsche Bank Trust Company Americas, as Trustee, Paying Agent, Transfer Agent and Registrar. This Note is one of a duly authorized issue of Notes of the Issuer designated as its [Insert title of the Notes] (the “Notes”). The terms of the Notes include those stated in the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture for a statement of them. The Notes are senior obligations of the Issuer. Additional Notes may be issued from time to time under the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time.

6. Ranking. The Notes will be senior unsecured obligations of the Issuer and will: (a) rank equally in right of payment with all of the Issuer’s existing and future indebtedness that is not subordinated in right of payment to the Notes; (b) rank senior in right of payment to all of the Issuer’s existing and future indebtedness that is subordinated in right of payment to the Notes; (c) be effectively junior to all of the Issuer’s existing and future secured indebtedness to the extent of the value of the collateral securing such other indebtedness; and (d) be structurally subordinated in right of payment to any obligations of Smurfit Westrock’s Subsidiaries other than Smurfit Westrock’s Subsidiaries that are Guarantors.

7. Optional Redemption. Except as set forth below in this Paragraph 7 or under Paragraph 8, none of the Notes will be redeemable prior to [·], [·].

[Any optionalredemption provisions to be included.]

8. Special Tax Redemption. The Issuer may, at its option, redeem the Notes in whole, but not in part, at any time upon giving not less than 10 nor more than 60 days’ notice to the Holders of the Notes (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption (a “Tax Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if a Payor determines that, as a result of: (1) any change in, or amendment to, the law or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation or (2) any change in position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) (each of the foregoing in clauses (1) and (2), a “Change in Tax Law”), the Payor or any Guarantor is, or on the next interest payment date in respect of the Notes would be, required to pay Additional Amounts with respect to the Notes, and the Payor or the relevant Guarantor (as appropriate) cannot avoid such obligation by taking reasonable measures available to it. In the case of the Issuer or any Guarantor as of the original issue date of the Notes, the Change in Tax Law must become effective on or after the original issue date of the Notes. In the case of a Successor Issuer or any Person who becomes a Guarantor after the original issue date of the Notes or any successor of any Guarantor, the Change in Tax Law must become effective after the date that the Issuer first makes payment on the Notes or after the date on which such Person became a Guarantor or a successor of any Guarantor, as applicable. Notice of redemption for taxation reasons will be published in accordance with the procedures set forth in the Indenture. Notwithstanding the foregoing, no such notice of redemption will be given earlier than 90 days prior to the earliest date on which the Payor or Guarantor, as applicable, would be obligated to make such payment or withholding if a payment in respect of the Notes were then due. Prior to the publication or mailing of any notice of redemption of the Notes pursuant to the foregoing, the Payor will deliver to the Trustee an opinion of an independent tax counsel reasonably satisfactory to the Trustee to the effect that the circumstances referred to above exist.

13. Legal Defeasance and Covenant Defeasance.

Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, interest, and Additional Amounts, if any, including an accelerated payment) if it determines that withholding notice is in their interest.

17. Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

In the Change of Control Offer, the Issuer will offer a payment (the “Changeof Control Payment”) in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid<br>interest and Additional Amounts, if any, thereon, to, but excluding, the date of purchase.<br><br><br><br><br><br><br><br>Within 60 days following any Change of Control<br>Repurchase Event, the Issuer will mail a notice to each Holder and the Trustee describing the transaction or transactions that constitute<br>the Change of Control Repurchase Event and offering to repurchase the Notes on a date (the “Change of Control Payment Date”)<br>specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant<br>to the procedures required by the Indenture and described in such notice.

To the extent that<br>the provisions of any securities laws or regulations conflict with these Change of Control Repurchase Event provisions, the Issuer will<br>comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under these Change<br>of Control Repurchase Event by virtue of such conflict.<br><br><br><br><br><br><br><br>On the Change of Control Payment Date, the Issuer<br>will, to the extent lawful:<br><br><br><br><br><br><br><br>(1)   accept<br>for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;<br><br><br><br><br><br><br><br>(2)   deposit<br>with the relevant Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered;<br>and<br><br><br><br><br><br><br><br>(3)   deliver<br>or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal<br>amount of the Notes or portions thereof being purchased by the Issuer.<br><br><br><br><br><br><br><br>The Paying Agent will promptly mail to each Holder<br>of the Notes so tendered the Change of Control Payment for the Notes and the Trustee or the relevant Registrar will, upon receipt of an<br>Issuer Order, promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount<br>to any unpurchased portion of any Notes surrendered, if any; provided that each such new Note will be in a principal amount of<br>$200,000 or an integral multiple of $1,000 in excess thereof.<br><br><br><br><br><br><br><br>In the case of Definitive Notes, if the Change<br>of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid<br>interest and Additional Amounts, if any, will be paid to the Person in whose name a Note is registered at the close of business on such<br>record date, and no additional interest or Additional Amounts will be payable to Holders who tender pursuant to the Change of Control<br>Offer; in the case of Global Notes, the Issuer will pay accrued and unpaid interest to the Change of Control Payment Date to the Holder<br>on such date.<br><br><br><br><br><br><br><br>The Issuer will publicly announce the results of the Change of Control<br>Offer on or as soon as practicable after the Change of Control Payment Date, and if and for so long as the Notes are listed on Euronext<br>Dublin, and the rules of Euronext Dublin so require, the Issuer will give notice with respect to the results of the Change of Control<br>Offer to the Companies Announcement Office of Euronext Dublin.
5
The provisions described above that<br>require the Issuer to make a Change of Control Offer following a Change of Control Repurchase Event will be applicable regardless of<br>whether any other provisions of the Indenture are applicable.<br><br> <br><br><br> <br>The Issuer will not be required to make a Change<br> of Control Offer with respect to the Notes following a Change of Control Repurchase Event if (i) an Affiliate of the Issuer or a<br> third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth<br> in this Officers’ Certificate applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered<br> and not withdrawn under such Change of Control Offer or (ii) a notice of redemption for all of the outstanding Notes has been given<br> as described herein under the caption “Optional Redemption” unless and until there is a default in the payment of the<br> applicable redemption price, plus accrued and unpaid interest to the proposed Redemption Date. Notwithstanding the foregoing, a Change<br> of Control Offer may be made in advance of a Change of Control Repurchase Event, conditional upon the Change of Control, so long as a<br> definitive agreement has been executed that contains terms and provisions that would otherwise result in a Change of Control upon completion<br> of the transactions contemplated thereby.<br><br> <br><br><br> <br>In connection with the provisions described above<br> that require the Issuer to make a Change of Control Offer following a Change of Control Repurchase Event, the following defined terms<br> apply:<br><br> <br><br><br> <br>“Change of Control” means the<br> occurrence of any of the following:<br><br> <br><br><br> <br>(1)   the<br> direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger, consolidation or transfer of Smurfit<br> Westrock’s Voting Stock), in one or a series of related transactions, of all or substantially all of the properties or assets of<br> Smurfit Westrock and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange<br> Act);<br><br> <br><br><br> <br>(2)   the<br> adoption of a plan relating to the liquidation or dissolution of the Issuer; or<br><br> <br><br><br> <br>(3)   the<br> consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person”<br> (as defined above) becomes the Beneficial Owner, directly or indirectly, of more than 50% of the Voting Stock of Smurfit Westrock, measured<br> by voting power rather than number of shares.<br><br> <br><br><br> <br>Notwithstanding the foregoing, a transaction<br>will not be deemed to involve a Change of Control if (i) the Ultimate Parent immediately prior to such transaction becomes a direct<br>or indirect wholly owned subsidiary of another Person and (ii)(A) the Beneficial Owners of the Voting Stock of such other Person<br>immediately following that transaction are substantially the same as the holders of the Voting Stock of the Ultimate Parent immediately<br>prior to that transaction or (B) immediately following that transaction no Person is the Beneficial Owner, directly or indirectly,<br>of more than 50% of the Voting Stock of such Person, measured by voting power rather than number of shares.

The Trustee shall not be responsible for monitoring or charged with knowledge of the ratings on the Notes.
Limitation on Issuance of Guarantees of Indebtedness by Subsidiaries: Smurfit Westrock will not cause or permit any<br> of its Subsidiaries that is not a Guarantor or the Issuer, directly or indirectly, to guarantee, assume or in any other manner become<br> liable for the payment of any Indebtedness of Smurfit Westrock or any of its Subsidiaries under the Existing Guarantee Covenant Notes<br> or any other Public Indebtedness unless, subject to the limitations set forth in the Indenture, such Subsidiary executes and delivers<br> a supplemental indenture to the Indenture providing for a Guarantee of payment of the Notes by such Subsidiary on the same terms as the<br> guarantee of such Indebtedness within 10 Business Days thereof; provided that if such Indebtedness is by its terms expressly subordinated<br> to the Notes or any Guarantee, any such guarantee, assumption or other liability of such Subsidiary with respect to such Indebtedness<br> shall be subordinated to such Subsidiary’s Guarantee of the Notes at least to the same extent as such Indebtedness is subordinated<br> to the Notes or any other Guarantee.<br><br> <br><br><br> <br>The obligations in the foregoing paragraph will<br> not be operative to the extent (1) the Notes have an Investment Grade rating from two or more Rating Agencies and (2) none of<br> the Existing Guarantee Covenant Notes benefit from a guarantee from such Subsidiary. The obligations in the foregoing paragraph will be<br> permanently terminated and no longer in effect as of the first date on which none of the Existing Guarantee Covenant Notes are outstanding.<br><br> <br><br><br> <br>To the extent any Subsidiary of Smurfit Westrock<br> is required to provide a Guarantee, such Guarantee will be limited as necessary to recognize certain defenses generally available to guarantors<br> (including those that relate to fraudulent conveyance or transfer, voidable preference, financial assistance, corporate purpose, capital<br> maintenance or similar laws, regulations or defenses affecting the rights of creditors generally) or other considerations under applicable<br> law.

Interest on the Notes will accrue at the rate of 5.185% per annum on the aggregate nominal amount of the Notes outstanding. Interest accruing on all Notes then outstanding shall be payable in cash. Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Any interest paid on this Note shall be increased to the extent necessary to pay Additional Amounts as set forth herein.

2.       Additional Amounts. All payments made by the Payor on the Notes or any Guarantor with respect to its Guarantee will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) imposed or levied by or on behalf of (1) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (2) any jurisdiction from or through which payment on the Notes or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (1) and (2), a “Relevant Taxing Jurisdiction”), unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes of any Relevant Taxing Jurisdiction shall at any time be required from any payments made with respect to the Notes or the Guarantees, including, without limitation, payments of principal, Redemption Price, interest or premium, if any, the Payor or the relevant Guarantor, as applicable, will pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by the Holders of the Notes or the Trustee, as the case may be, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), equal the amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no such Additional Amounts will be payable with respect to:

(1)       any Taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction upon any payments to a Holder or Beneficial Owner who is liable for such Taxes in respect of the Notes by reason of the Holder (or a fiduciary, settlor, beneficiary, member, partner or shareholder of, or possessor of power over the relevant Holder, if the relevant Holder is an estate, nominee, trust, partnership, limited liability company or corporation) or Beneficial Owner having any present or former connection with such Relevant Taxing Jurisdiction (including, without limitation, being resident for tax purposes, being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Relevant Taxing Jurisdiction) other than a connection arising from the acquisition, ownership or holding of such Note or enforcement of rights thereunder or the receipt of payments in respect of the Notes or with respect to any Guarantee;

(2)       any Taxes that would not have been imposed if the Holder or Beneficial Owner had made a declaration of non-residence or any other claim or filing for exemption to which it is entitled (provided that (x) such declaration of non-residence or other claim or filing for exemption is required by the applicable law of the applicable Relevant Taxing Jurisdiction as a precondition to exemption from the requirement to deduct or withhold such Taxes and (y) at least 30 days prior to the first payment date with respect to which such declaration of non-residence or other claim or filing for exemption is required under the applicable law of the applicable Relevant Taxing Jurisdiction, the relevant Holder or Beneficial Owner at that time has been notified in writing by the Payor or any other person through whom payment may be made that a declaration of non-residence or other claim or filing for exemption is required to be made);

A-5

(3)       except in the case of the winding up of the Payor, any Note presented for payment (where presentation is required) in the Relevant Taxing Jurisdiction (unless by reason of the Payor’s actions, presentment could not have been made elsewhere and except to the extent that the Holder would have been entitled to Additional Amounts had the Notes been presented elsewhere);

(4)       any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented during such 30 day period);

(5)       any Taxes that are payable otherwise than by withholding from a payment of the principal of, premium, if any, or interest, if any, on the Notes or with respect to any Guarantee;

(6)       any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or other governmental charge;

(7)       a Tax imposed in connection with a Note presented for payment by or on behalf of a Holder or Beneficial Owner who would have been able to avoid such Tax by presenting the Note to, or otherwise accept payment from, another paying agent in a member state of the European Union;

(8)       any Taxes imposed, deducted or withheld pursuant to Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code, in each case, as of the Original Issue Date (and any amended or successor version that is substantively comparable); any current or future regulations or agreements thereunder, official interpretations thereof or any law implementing an intergovernmental agreement relating thereto; or any treaty, law, regulation or other official guidance enacted in any other jurisdiction, facilitating implementation thereof;

(9)       all United States backup withholding taxes;

(10)       any Tax deducted, withheld or imposed in connection with the Dutch Withholding Tax Act 2021 (Wet bronbelasting 2021), as amended from time to time; or

(11)       any combination of clauses (1) through (10) above.

Such Additional Amounts will also not be payable where, had the Beneficial Owner of the Note been the Holder of the Note, it would not have been entitled to payment of Additional Amounts by reason of clauses (1) to (11) inclusive above.

Upon request, the Issuer will provide the Trustee with documentation satisfactory to the Trustee evidencing the payment of Additional Amounts. Copies of such documentation will be made available to the Holders upon request.

3.       Method of Payment. The Issuer shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders at the close of business on the Record Date with respect to such Notes immediately preceding the interest payment date for such interest. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay all amounts owing hereunder in Dollars. Immediately available funds for the payment of the principal of, premium, if any, interest and Additional Amounts, if any, on this Note due on any interest payment date, maturity date, Redemption Date or other repurchase date will be made available to the Paying Agent to permit the Paying Agent to pay such funds to the Holders on such respective dates.

4.       Paying Agent, Registrar and Transfer Agent. Initially, Deutsche Bank Trust Company Americas will act as Paying Agent, Registrar and Transfer Agent. In the event that a Paying Agent or Transfer Agent is replaced, the Issuer will provide notice thereof as set forth in the Indenture. The Issuer may change any Registrar without notice to the Holders. The Issuer or any of its Subsidiaries may, subject to certain exceptions, act in any such capacity.

A-6

5.       Indenture. The Issuer issued the Notes under a base indenture, dated as of November 21, 2025 (the “Base Indenture”), as supplemented by an Officers’ Certificate, dated November 21, 2025, pursuant to Sections 2.1 and 12.4 of the Base Indenture (together with the Base Indenture, the “Indenture”), establishing certain terms of the Notes, among the Issuer, the Guarantors and Deutsche Bank Trust Company Americas, as Trustee, Paying Agent, Transfer Agent and Registrar. This Note is one of a duly authorized issue of Notes of the Issuer designated as its 5.185% Senior Notes due 2036 (the “Notes”). The terms of the Notes include those stated in the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture for a statement of them. The Notes are senior obligations of the Issuer. Additional Notes may be issued from time to time under the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time.

6.       Ranking. The Notes will be senior unsecured obligations of the Issuer and will: (a) rank equally in right of payment with all of the Issuer’s existing and future Indebtedness that is not subordinated in right of payment to the Notes; (b) rank senior in right of payment to all of the Issuer’s existing and future Indebtedness that is subordinated in right of payment to the Notes; (c) be effectively junior to all of the Issuer’s existing and future secured Indebtedness to the extent of the value of the collateral securing such other Indebtedness; and (d) be structurally subordinated in right of payment to any obligations of Smurfit Westrock’s Subsidiaries other than Smurfit Westrock’s Subsidiaries that are Guarantors.

7.       Optional Redemption. Except as set forth below in this Paragraph 7 or under Paragraph 8, none of the Notes will be redeemable prior to January 15, 2036.

Prior to October 15, 2035 (the date that is three months prior to the scheduled maturity of the Notes) (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 (a) 100% of the principal amount of the Notes to be redeemed and (b) (i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed are scheduled to mature on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, less (ii) interest accrued to the date of redemption, plus, in either case, accrued and unpaid interest thereon and Additional Amounts, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Amounts, if any, thereon, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, any redemption price shall be calculated by the Issuer, or on behalf of the Issuer by such Person as the Issuer may engage, and the calculation of the redemption price shall not be an obligation or duty of the Trustee or the Paying Agent. Neither the Trustee nor any Paying Agent shall be responsible for determining or verifying the Company’s determination of the redemption price.

Any such redemption and notice may, in the Issuer’s discretion, be subject to the satisfaction of one or more conditions precedent, and such notice may state that, in the Issuer’s discretion, the Redemption Date may be delayed without any additional notice until such time as any or all such conditions shall be satisfied.

In the case of a partial redemption of the Notes, selection of the Notes to be redeemed shall be made in the manner described in Section 3.3 of the Indenture.

A-7

If and for so long as the Notes to be redeemed are admitted to the Global Exchange Market of Euronext Dublin and the rules of Euronext Dublin so require, not less than 10 nor more than 60 days prior to the Redemption Date, the Issuer will mail notice of redemption to Holders by first class mail, postage prepaid, or otherwise in accordance with the applicable procedures of DTC, to each Holder of Notes to be redeemed, at such Holder’s address appearing in the Register. Such notice of redemption may also be posted on the official website of Euronext Dublin (www.ise.ie), to the extent and in the manner permitted by the rules of Euronext Dublin.

In connection with this Paragraph 7, the following defined term applies:

Treasury Rate” means, as of any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs:

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to such Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than such Remaining Life — and shall interpolate to such Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than such Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Issuer shall calculate the applicable 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 Par Call Date. If there is no United States Treasury security maturing on such Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date and one with a maturity date following such Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on such Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

8.       Special Tax Redemption. The Issuer may, at its option, redeem the Notes in whole, but not in part, at any time upon giving not less than 10 nor more than 60 days’ notice to the Holders of the Notes (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption (a “Tax Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if a Payor determines that, as a result of: (1) any change in, or amendment to, the law or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation or (2) any change in position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) (each of the foregoing in clauses (1) and (2), a “Change in TaxLaw”), the Payor or any Guarantor is, or on the next interest payment date in respect of the Notes would be, required to pay Additional Amounts with respect to the Notes, and the Payor or the relevant Guarantor (as appropriate) cannot avoid such obligation by taking reasonable measures available to it. In the case of the Issuer or any Guarantor as of the original issue date of the Notes, the Change in Tax Law must become effective on or after the original issue date of the Notes. In the case of a Successor Issuer or any Person who becomes a Guarantor after the original issue date of the Notes or any successor of any Guarantor, the Change in Tax Law must become effective after the date that the Issuer first makes payment on the Notes or after the date on which such Person became a Guarantor or a successor of any Guarantor, as applicable. Notice of redemption for taxation reasons will be published in accordance with the procedures set forth in the Indenture. Notwithstanding the foregoing, no such notice of redemption will be given earlier than 90 days prior to the earliest date on which the Payor or Guarantor, as applicable, would be obligated to make such payment or withholding if a payment in respect of the Notes were then due. Prior to the publication or mailing of any notice of redemption of the Notes pursuant to the foregoing, the Payor will deliver to the Trustee an opinion of an independent tax counsel reasonably satisfactory to the Trustee to the effect that the circumstances referred to above exist. The Trustee will accept such opinion as sufficient existence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders of the Notes.

A-8

9.       Guarantees. The payment by the Issuer of the principal of, premium, if any, interest and Additional Amounts, if any, on the Notes and all other obligations of the Issuer under the Indenture is, subject to Section 11.2 of the Indenture and limitations under applicable law, fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by each of the Guarantors to the extent set forth in the Indenture.

10.       Denominations; Form; Transfer and Exchange. The Global Notes are in registered form, without coupons, in denominations of $200,000 and integral multiples of $1,000 in excess thereof. The Trustee, the Registrar, the Paying Agent and the Transfer Agent may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay all taxes and fees required by law or permitted by the Indenture.

11.       Persons Deemed Owners. The registered Holder of this Note shall be treated as the owner of it for all purposes, subject to the terms of the Indenture.

12.       Unclaimed Funds. If funds for the payment of principal of, premium, if any, interest and Additional Amounts, if any, on the Notes remain unclaimed for two years, the Trustee and the Paying Agents will repay the funds to the Issuer at its written request. After that, all liability of the Trustee and such Paying Agents with respect to such funds shall cease.

13.       Legal Defeasance and Covenant Defeasance. The Issuer may be discharged from its obligations under the Indenture and the Notes except for certain provisions thereof, and may be discharged from its obligations to comply with certain covenants contained in the Indenture, in each case upon satisfaction of certain conditions specified in the Indenture.

14.       Amendment; Supplement; Waiver. Subject to certain exceptions specified in the Indenture, the Indenture, the Notes or the Guarantees may be amended or supplemented with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding.

15.       Successors. When a successor assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

16.       Defaults and Remedies. Subject to certain restrictions, if an Event of Default (other than an Event of Default specified in clause (4) of Section 7.1 of the Base Indenture) occurs and is continuing with respect to the Notes, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, interest, and Additional Amounts, if any, including an accelerated payment) if it determines that withholding notice is in their interest.

A-9

17.       Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

18.       No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

19.       Authentication. This Note shall not be valid until the Trustee or Authenticating Agent signs, by manual, electronic or facsimile signature, the certificate of authentication on this Note.

20.       Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

SMURFITWESTROCK FINANCING DESIGNATED ACTIVITY COMPANY

5.185% SENIOR NOTES DUE 2036

1.       Interest. SMURFIT WESTROCK FINANCING DESIGNATED ACTIVITY COMPANY, a designated activity company incorporated under the laws of Ireland and having its registered office at Beech Hill, Clonskeagh, Dublin 4, Ireland (the “Issuer”), promises to pay interest on the principal amount of this Note at the rate and in the manner specified below. Interest on the Notes will be payable semi-annually in arrears on January 15 and July 15 of each year, commencing July 15, 2026. The Issuer will make each interest payment to the Holders of record at the close of business on the immediately preceding January 1 and July 1 of each year. Rights of holders of beneficial interests to receive such payments will be subject to applicable procedures of DTC. Interest on the Notes will accrue at the rate of 5.185% per annum on the aggregate nominal amount of the Notes outstanding. Interest accruing on all Notes then outstanding shall be payable in cash. Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid.

Any interest paid on this Note shall be increased to the extent necessary to pay Additional Amounts as set forth herein.

2.       Additional Amounts. All payments made by the Payor on the Notes or any Guarantor with respect to its Guarantee will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) imposed or levied by or on behalf of (1) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (2) any jurisdiction from or through which payment on the Notes or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (1) and (2), a “Relevant Taxing Jurisdiction”), unless the withholding or deduction of such Taxes is then required by law.

(4)       any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented during such 30 day period);

(5)       any Taxes that are payable otherwise than by withholding from a payment of the principal of, premium, if any, or interest, if any, on the Notes or with respect to any Guarantee;

(6)       any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or other governmental charge;

3.       Method of Payment. The Issuer shall pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders at the close of business on the Record Date with respect to such Notes immediately preceding the interest payment date for such interest. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuer shall pay all amounts owing hereunder in Dollars. With respect to payments in Dollars, if (i) a Holder has given wire transfer instructions to the Issuer and the Paying Agent in writing and (ii) the Paying Agent has received such written wire transfer instruction at least 15 days prior to the date of the relevant payment, then the Issuer will pay all interest, premium and Additional Amounts, if any, on that Holder’s Notes in accordance with those instructions by wire transfer of same day funds to the Paying Agent who in turn will wire such funds to the Holder hereof or to such other Person as the Holder hereof may in writing to the Paying Agent direct. In all other cases, the Issuer may elect to make payments of interest, premium and Additional Amounts, if any, on a Holder’s Notes by check mailed to the Holders at their addresses set forth in the register of Holders. Payments on Notes will be made through the office or agency of the Paying Agent and Registrar for the Notes unless the Issuer elects to make interest payments by check as previously described. If payments are made through the Paying Agent, immediately available funds for the payment of the principal of, premium, if any, interest and Additional Amounts, if any, on this Note due on any interest payment date, maturity date, Redemption Date or other repurchase date will be made available to the Paying Agent to permit the Paying Agent to pay such funds to the Holders on such respective dates.

4.       Paying Agent, Registrar and Transfer Agent. Initially, Deutsche Bank Trust Company Americas will act as Paying Agent, Registrar and Transfer Agent. In the event that a Paying Agent or Transfer Agent is replaced, the Issuer will provide notice thereof as set forth in the Indenture. The Issuer may change any Registrar without notice to the Holders. The Issuer or any of its Subsidiaries may, subject to certain exceptions, act in any such capacity.

5.       Indenture. The Issuer issued the Notes under a base indenture, dated as of November 21, 2025 (the “Base Indenture”), as supplemented by an Officers’ Certificate, dated November 21, 2025, pursuant to Sections 2.1 and 12.4 of the Base Indenture (together with the Base Indenture, the “Indenture”), establishing certain terms of the Notes, among the Issuer, the Guarantors and Deutsche Bank Trust Company Americas, as Trustee, Paying Agent, Transfer Agent and Registrar. This Note is one of a duly authorized issue of Notes of the Issuer designated as its 5.185% Senior Notes due 2036 (the “Notes”). The terms of the Notes include those stated in the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture for a statement of them. The Notes are senior obligations of the Issuer. Additional Notes may be issued from time to time under the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time.

6.       Ranking. The Notes will be senior unsecured obligations of the Issuer and will: (a) rank equally in right of payment with all of the Issuer’s existing and future Indebtedness that is not subordinated in right of payment to the Notes; (b) rank senior in right of payment to all of the Issuer’s existing and future Indebtedness that is subordinated in right of payment to the Notes; (c) be effectively junior to all of the Issuer’s existing and future secured Indebtedness to the extent of the value of the collateral securing such other Indebtedness; and (d) be structurally subordinated in right of payment to any obligations of Smurfit Westrock’s Subsidiaries other than Smurfit Westrock’s Subsidiaries that are Guarantors.

7.       Optional Redemption. Except as set forth below in this Paragraph 7 or under Paragraph 8, none of the Notes will be redeemable prior to January 15, 2036.

Prior to October 15, 2035 (the date that is three months prior to the scheduled maturity of the Notes) (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 (a) 100% of the principal amount of the Notes to be redeemed and (b) (i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed are scheduled to mature on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, less (ii) interest accrued to the date of redemption, plus, in either case, accrued and unpaid interest thereon and Additional Amounts, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

B-7

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Amounts, if any, thereon, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, any redemption price shall be calculated by the Issuer, or on behalf of the Issuer by such Person as the Issuer may engage, and the calculation of the redemption price shall not be an obligation or duty of the Trustee or the Paying Agent. Neither the Trustee nor any Paying Agent shall be responsible for determining or verifying the Company’s determination of the redemption price.

Any such redemption and notice may, in the Issuer’s discretion, be subject to the satisfaction of one or more conditions precedent, and such notice may state that, in the Issuer’s discretion, the Redemption Date may be delayed without any additional notice until such time as any or all such conditions shall be satisfied.

In the case of a partial redemption of the Notes, selection of the Notes to be redeemed shall be made in the manner described in Section 3.3 of the Indenture.

If and for so long as the Notes to be redeemed are admitted to the Global Exchange Market of Euronext Dublin and the rules of Euronext Dublin so require, not less than 10 nor more than 60 days prior to the Redemption Date, the Issuer will mail notice of redemption to Holders by first class mail, postage prepaid, or otherwise in accordance with the applicable procedures of DTC, to each Holder of Notes to be redeemed, at such Holder’s address appearing in the Register. Such notice of redemption may also be posted on the official website of Euronext Dublin (www.ise.ie), to the extent and in the manner permitted by the rules of Euronext Dublin.

In connection with this Paragraph 7, the following defined term applies:

Treasury Rate” means, as of any Redemption Date, the yield determined by the Issuer in accordance with the following two paragraphs:

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to such Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than such Remaining Life — and shall interpolate to such Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than such Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

B-8

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Issuer shall calculate the applicable 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 Par Call Date. If there is no United States Treasury security maturing on such Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date and one with a maturity date following such Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on such Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

8.       Special Tax Redemption. The Issuer may, at its option, redeem the Notes in whole, but not in part, at any time upon giving not less than 10 nor more than 60 days’ notice to the Holders of the Notes (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption (a “Tax Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if a Payor determines that, as a result of: (1) any change in, or amendment to, the law or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation or (2) any change in position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) (each of the foregoing in clauses (1) and (2), a “Change in TaxLaw”), the Payor or any Guarantor is, or on the next interest payment date in respect of the Notes would be, required to pay Additional Amounts with respect to the Notes, and the Payor or the relevant Guarantor (as appropriate) cannot avoid such obligation by taking reasonable measures available to it. In the case of the Issuer or any Guarantor as of the original issue date of the Notes, the Change in Tax Law must become effective on or after the original issue date of the Notes. In the case of a Successor Issuer or any Person who becomes a Guarantor after the original issue date of the Notes or any successor of any Guarantor, the Change in Tax Law must become effective after the date that the Issuer first makes payment on the Notes or after the date on which such Person became a Guarantor or a successor of any Guarantor, as applicable. Notice of redemption for taxation reasons will be published in accordance with the procedures set forth in the Indenture. Notwithstanding the foregoing, no such notice of redemption will be given earlier than 90 days prior to the earliest date on which the Payor or Guarantor, as applicable, would be obligated to make such payment or withholding if a payment in respect of the Notes were then due. Prior to the publication or mailing of any notice of redemption of the Notes pursuant to the foregoing, the Payor will deliver to the Trustee an opinion of an independent tax counsel reasonably satisfactory to the Trustee to the effect that the circumstances referred to above exist. The Trustee will accept such opinion as sufficient existence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders of the Notes.

9.       Guarantees. The payment by the Issuer of the principal of, premium, if any, interest or Additional Amounts, if any, on the Notes and all other obligations of the Issuer under the Indenture is, subject to Section 11.2 of the Indenture and limitations under applicable law, fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by each of the Guarantors to the extent set forth in the Indenture.

10.       Denominations; Form; Transfer and Exchange. The Notes are in definitive registered form, without coupons, in denominations of $200,000 and integral multiples of $1,000 in excess thereof. The Trustee, the Registrar, the Paying Agent and the Transfer Agent may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay all taxes and fees required by law or permitted by the Indenture.

B-9

11.       Persons Deemed Owners. The registered Holder of this Note shall be treated as the owner of it for all purposes, subject to the terms of the Indenture.

12.       Unclaimed Funds. If funds for the payment of principal of, premium, if any, interest and Additional Amounts, if any, on the Notes remain unclaimed for two years, the Trustee and the Paying Agents will repay the funds to the Issuer at its written request. After that, all liability of the Trustee and such Paying Agents with respect to such funds shall cease.

13.       Legal Defeasance and Covenant Defeasance. The Issuer may be discharged from its obligations under the Indenture and the Notes except for certain provisions thereof, and may be discharged from its obligations to comply with certain covenants contained in the Indenture, in each case upon satisfaction of certain conditions specified in the Indenture.

14.       Amendment; Supplement; Waiver. Subject to certain exceptions specified in the Indenture, the Indenture, the Notes or the Guarantees may be amended or supplemented with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding.

15.       Successors. When a successor assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

16.       Defaults and Remedies. Subject to certain restrictions, if an Event of Default (other than an Event of Default specified in clause (4) of Section 7.1 of the Base Indenture) occurs and is continuing with respect to the Notes, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, interest, and Additional Amounts, if any, including an accelerated payment) if it determines that withholding notice is in their interest.

17.       Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

18.       No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

19.       Authentication. This Note shall not be valid until the Trustee or Authenticating Agent signs, by manual, electronic or facsimile signature, the certificate of authentication on this Note.

20.       Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

The Notes may be surrendered for registration, transfer, exchange or conversion as set forth in the Indenture at the Place of Payment
Optional Redemption: As set forth in Section 3.1 of the Indenture and<br> in the form of the Notes attached hereto as Exhibit A, the Issuer may redeem the Notes at its option, in whole or in part, at any time<br> and from time to time.<br><br> <br><br><br> <br>Prior to August 24, 2031 (the date that is<br> three months prior to the scheduled maturity of the Notes) (the “Par Call Date”), the Issuer may redeem the Notes at<br> 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<br> and rounded to three decimal places) equal to the greater of (a) 100% of the principal amount of the Notes to be redeemed and (b) (i)<br> the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date<br> (assuming the Notes to be redeemed are scheduled to mature on the Par Call Date) on an annual basis (ACTUAL/ACTUAL (ICMA)) as the Comparable<br> Government Bond Rate (as defined in Exhibit A) plus 20 basis points, less (ii) interest accrued to the date of redemption, plus,<br> in either case, accrued and unpaid interest thereon and Additional Amounts, if any, to, but excluding, the Redemption Date (subject to<br> the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).<br><br> <br><br><br> <br>On or after the Par Call Date, the Issuer may<br> redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount<br> of the Notes to be redeemed, plus accrued and unpaid interest and Additional Amounts, if any, thereon, to, but excluding, the Redemption<br> Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).
3
The Issuer’s actions and determinations<br>in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt,<br>any redemption price shall be calculated by the Issuer, or on behalf of the Issuer by such Person as the Issuer may engage, and the calculation<br>of the redemption price shall not be an obligation or duty of the Trustee or the Paying Agent. Neither the Trustee nor any Paying Agent<br>shall be responsible for determining or verifying the Company’s determination of the redemption price.<br><br><br><br><br><br><br><br>Any such redemption and notice may, in the Issuer’s<br>discretion, be subject to the satisfaction of one or more conditions precedent, and such notice may state that, in the Issuer’s<br>discretion, the Redemption Date may be delayed without any additional notice until such time as any or all such conditions shall be satisfied.<br><br><br><br><br><br><br><br>In the case of a partial redemption of the Notes,<br>selection of the Notes to be redeemed shall be made in the manner described in Section 3.3 of the Indenture.<br><br><br><br><br><br><br><br>If and for so long as the Notes to be redeemed<br>are admitted to the Global Exchange Market of Euronext Dublin and the rules of Euronext Dublin so require, not less than 10 nor more than<br>60 days prior to the Redemption Date, the Issuer will mail notice of redemption to Holders by first class mail, postage prepaid, or otherwise<br>in accordance with the applicable procedures of Euroclear or Clearstream, to each Holder of Notes to be redeemed, at such Holder’s<br>address appearing in the Register. Such notice of redemption may also be posted on the official website of Euronext Dublin (www.ise.ie),<br>to the extent and in the manner permitted by the rules of Euronext Dublin.<br><br><br><br><br><br><br><br>Except pursuant to the preceding paragraphs and except as described<br>below under “Tax Redemption”, the Notes will not be redeemable at the Issuer’s option.
Tax Redemption: As set forth in Section 4.7 of the Indenture and in Paragraph 8 of the form of the Notes attached hereto as Exhibit A, in the event of certain tax law changes that would require the Issuer or any Guarantor to pay Additional Amounts, the Issuer may redeem the Notes in whole, but not in part, at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption, and all Additional Amounts, if any.
Sinking Fund The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.
Events of Default: Section 7.1 of the Indenture is hereby supplemented<br> such that “Event of Default” also means the following event which shall have occurred and be continuing:<br><br> <br><br><br> <br>(5) default under any mortgage, indenture or instrument<br> under which there is issued and outstanding any Indebtedness for money borrowed by Smurfit Westrock or any of its Subsidiaries (or the<br> payment of which is guaranteed by Smurfit Westrock or any of its Subsidiaries) whether such Indebtedness or guarantee now exists, or is<br> created after the date of the Indenture, if that default:<br><br> <br><br><br> <br>(a)   is<br> caused by a failure to pay principal at the final stated maturity of such Indebtedness (after giving effect to any applicable grace period<br> provided in the Indebtedness) (a “Payment Default”); or<br><br> <br><br><br> <br>(b)   results<br> in the acceleration of such Indebtedness prior to its express maturity;
4
and in each case, the principal amount of any<br>such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the<br>maturity of which has been so accelerated, aggregates $300.0 million or more.<br><br><br><br><br><br><br><br>In the event of any Event of Default specified<br>in clause (5), above, such Event of Default and all consequences thereof (including, without limitation, any acceleration or resulting<br>payment default) shall be annulled, waived and rescinded automatically and without any action by the Trustee or the Holders, if within<br>30 days after such Event of Default arose, (x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged,<br>(y) the creditors on such Indebtedness have rescinded or waived the acceleration, notice or action, as the case may be, giving rise to<br>such Event of Default or (z) if the default that is the basis for such Event of Default has been cured.<br><br><br><br><br><br><br><br>In the case of any Event of Default occurring by reason of any willful<br>action (or inaction) taken (or not taken) by or on behalf of the Issuer in bad faith with the intention of avoiding payment of the premium<br>that the Issuer would have had to pay if the Issuer then had elected to redeem the Notes pursuant to the optional redemption provisions<br>of the Indenture or was required to repurchase the Notes, an equivalent premium shall also become and be immediately due and payable<br>to the extent permitted by law upon the acceleration of the Notes.
Defeasance and Discharge of the Notes (Sections 9.2 and 9.3 of the Indenture): Applicable
Change of Control: If a Change of Control Repurchase Event occurs,<br>each Holder will have the right to require the Issuer to repurchase all or any part (equal to €100,000 and integral multiples of<br> €1,000 in excess thereof in the case of Notes that have denominations larger than €100,000) of that Holder’s Notes pursuant<br>to an offer (the “Change of Control Offer”). In the Change of Control Offer, the Issuer will offer a payment (the “Changeof Control Payment”) in cash equal to 100% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid<br>interest and Additional Amounts, if any, thereon, to, but excluding, the date of purchase.<br><br><br><br><br><br><br><br>Within 60 days following any Change of Control Repurchase Event, the<br>Issuer will mail a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control<br>Repurchase Event and offering to repurchase the Notes on a date (the “Change of Control Payment Date”) specified in<br>such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the<br>procedures required by the Indenture and described in such notice. The Issuer will comply with the requirements of Section 14(e) of the<br>Exchange Act to the extent applicable and any other securities laws and regulations thereunder to the extent such laws and regulations<br>are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that<br>the provisions of any securities laws or regulations conflict with these Change of Control Repurchase Event provisions, the Issuer will<br>comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under these Change<br>of Control Repurchase Event by virtue of such conflict.
5
On the Change of Control Payment Date, the Issuer<br> will, to the extent lawful:<br><br> <br><br><br> <br>(1)   accept<br> for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;<br><br> <br><br><br> <br>(2)   deposit<br> with the relevant Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered;<br> and<br><br> <br><br><br> <br>(3)   deliver<br> or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal<br> amount of the Notes or portions thereof being purchased by the Issuer.<br><br> <br><br><br> <br>The Paying Agent will promptly mail to each Holder<br> of the Notes so tendered the Change of Control Payment for the Notes and the Trustee or the relevant Registrar will, upon receipt of an<br> Issuer Order, promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount<br> to any unpurchased portion of any Notes surrendered, if any; provided that each such new Note will be in a principal amount of<br> €100,000 or an integral multiple of €1,000 in excess thereof.<br><br> <br><br><br> <br>In the case of Definitive Notes, if the Change<br> of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid<br> interest and Additional Amounts, if any, will be paid to the Person in whose name a Note is registered at the close of business on such<br> record date, and no additional interest or Additional Amounts will be payable to Holders who tender pursuant to the Change of Control<br> Offer; in the case of Global Notes, the Issuer will pay accrued and unpaid interest to the Change of Control Payment Date to the Holder<br> on such date.<br><br> <br><br><br> <br>The Issuer will publicly announce the results<br> of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date, and if and for so long as the Notes<br> are listed on Euronext Dublin, and the rules of Euronext Dublin so require, the Issuer will give notice with respect to the results of<br> the Change of Control Offer to the Companies Announcement Office of Euronext Dublin.<br><br> <br><br><br> <br>The provisions described above that require the<br> Issuer to make a Change of Control Offer following a Change of Control Repurchase Event will be applicable regardless of whether any other<br> provisions of the Indenture are applicable.<br><br> <br><br><br> <br>The Issuer will not be required to make a Change<br> of Control Offer with respect to the Notes following a Change of Control Repurchase Event if (i) an Affiliate of the Issuer or a<br> third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth<br> in this Officers’ Certificate applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered<br> and not withdrawn under such Change of Control Offer or (ii) a notice of redemption for all of the outstanding Notes has been given<br> as described herein under the caption “Optional Redemption” unless and until there is a default in the payment of the<br> applicable redemption price, plus accrued and unpaid interest to the proposed Redemption Date. Notwithstanding the foregoing, a Change<br> of Control Offer may be made in advance of a Change of Control Repurchase Event, conditional upon the Change of Control, so long as a<br> definitive agreement has been executed that contains terms and provisions that would otherwise result in a Change of Control upon completion<br> of the transactions contemplated thereby.
6
In connection with the provisions described above<br>that require the Issuer to make a Change of Control Offer following a Change of Control Repurchase Event, the following defined terms<br>apply:<br><br><br><br><br><br><br><br>“Change of Control” means the<br>occurrence of any of the following:<br><br><br><br><br><br><br><br>(1)   the<br>direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger, consolidation or transfer of Smurfit<br>Westrock’s Voting Stock), in one or a series of related transactions, of all or substantially all of the properties or assets of<br>Smurfit Westrock and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange<br>Act);<br><br><br><br><br><br><br><br>(2)   the<br>adoption of a plan relating to the liquidation or dissolution of the Issuer; or<br><br><br><br><br><br><br><br>(3)   the<br>consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person”<br>(as defined above) becomes the Beneficial Owner, directly or indirectly, of more than 50% of the Voting Stock of Smurfit Westrock, measured<br>by voting power rather than number of shares.<br><br><br><br><br><br><br><br><br><br><br><br>Notwithstanding the foregoing, a transaction will<br>not be deemed to involve a Change of Control if (i) the Ultimate Parent immediately prior to such transaction becomes a direct or<br>indirect wholly owned subsidiary of another Person and (ii)(A) the Beneficial Owners of the Voting Stock of such other Person immediately<br>following that transaction are substantially the same as the holders of the Voting Stock of the Ultimate Parent immediately prior to that<br>transaction or (B) immediately following that transaction no Person is the Beneficial Owner, directly or indirectly, of more than<br>50% of the Voting Stock of such Person, measured by voting power rather than number of shares.<br><br><br><br><br><br><br><br>“Change of Control Repurchase Event”<br>means a Change of Control and a Rating Event.<br><br><br><br><br><br><br><br>“Rating Date” means the date<br>of first public announcement of an event that constitutes a Change of Control.<br><br><br><br><br><br><br><br>“Rating Event” means that<br>any time within a 90 day period from the Rating Date (which period shall be extended for up to, but no longer than, an additional 90<br>days so long as any Rating Agency has publicly announced that it is considering a possible downgrade of the Notes), (i) the rating<br>on the Notes is lowered by at least one Rating Agency and (ii) the Notes are rated below an Investment Grade rating by at least<br>two Rating Agencies, if the Notes are rated by all three Rating Agencies, or by each Rating Agency, if the Notes are rated by fewer than<br>three Rating Agencies; provided that a Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed<br>to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Rating Event for purposes of the definition<br>of Change of Control Repurchase Event hereunder) if the Rating Agency or Rating Agencies, as applicable, making the reduction in rating<br>to which this definition would otherwise apply does or do not announce or publicly confirm or inform us in writing that the reduction<br>was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable<br>Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Rating Event). The Trustee<br>shall not be responsible for monitoring or charged with knowledge of the ratings on the Notes.
7
Limitation on Issuance of Guarantees of Indebtedness by Subsidiaries: Smurfit Westrock will not cause or permit any<br> of its Subsidiaries that is not a Guarantor or the Issuer, directly or indirectly, to guarantee, assume or in any other manner become<br> liable for the payment of any Indebtedness of Smurfit Westrock or any of its Subsidiaries under the Existing Guarantee Covenant Notes<br> or any other Public Indebtedness unless, subject to the limitations set forth in the Indenture, such Subsidiary executes and delivers<br> a supplemental indenture to the Indenture providing for a Guarantee of payment of the Notes by such Subsidiary on the same terms as the<br> guarantee of such Indebtedness within 10 Business Days thereof; provided that if such Indebtedness is by its terms expressly subordinated<br> to the Notes or any Guarantee, any such guarantee, assumption or other liability of such Subsidiary with respect to such Indebtedness<br> shall be subordinated to such Subsidiary’s Guarantee of the Notes at least to the same extent as such Indebtedness is subordinated<br> to the Notes or any other Guarantee.<br><br> <br><br><br> <br>The obligations in the foregoing paragraph will<br> not be operative to the extent (1) the Notes have an Investment Grade rating from two or more Rating Agencies and (2) none of<br> the Existing Guarantee Covenant Notes benefit from a guarantee from such Subsidiary. The obligations in the foregoing paragraph will be<br> permanently terminated and no longer in effect as of the first date on which none of the Existing Guarantee Covenant Notes are outstanding.<br><br> <br><br><br> <br>To the extent any Subsidiary of Smurfit Westrock<br> is required to provide a Guarantee, such Guarantee will be limited as necessary to recognize certain defenses generally available to guarantors<br> (including those that relate to fraudulent conveyance or transfer, voidable preference, financial assistance, corporate purpose, capital<br> maintenance or similar laws, regulations or defenses affecting the rights of creditors generally) or other considerations under applicable<br> law.
No Personal Liability of Directors, Officers, Employees and Stockholders: Section 12.9 of the Indenture is hereby restated<br> in its entirety:<br><br> <br><br><br> <br>No director, officer, employee, incorporator or<br> stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under<br> the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.<br> Each Holder of Notes by accepting a Note waives and releases all such liability.

SMURFITKAPPA TREASURY UNLIMITED COMPANY

3.489% SENIOR NOTES DUE 2031

1.       Interest. SMURFIT KAPPA TREASURY UNLIMITED COMPANY, a public unlimited company incorporated under the laws of Ireland and having its registered office at Beech Hill, Clonskeagh, Dublin 4, Ireland (the “Issuer”), promises to pay interest on the principal amount of this Note at the rate and in the manner specified below. Interest on the Notes will be payable annually in arrears on November 24 of each year, commencing November 24, 2026. The Issuer will make each interest payment to the Holders of record at the close of business on the Business Day (for this purpose a day on which Clearstream and Euroclear are open for business) immediately preceding the interest payment date. Rights of holders of beneficial interests to receive such payments will be subject to applicable procedures of Euroclear or Clearstream. Interest on the Notes will accrue at the rate of 3.489% per annum on the aggregate nominal amount of the Notes outstanding. Interest accruing on all Notes then outstanding shall be payable in cash. Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid or duly provided for on the Notes (or the date of original issuance 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 Market Association.

Any interest paid on this Note shall be increased to the extent necessary to pay Additional Amounts as set forth herein.

2.       Additional Amounts. All payments made by the Payor on the Notes or any Guarantor with respect to its Guarantee will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) imposed or levied by or on behalf of (1) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (2) any jurisdiction from or through which payment on the Notes or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (1) and (2), a “Relevant Taxing Jurisdiction”), unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes of any Relevant Taxing Jurisdiction shall at any time be required from any payments made with respect to the Notes or the Guarantees, including, without limitation, payments of principal, Redemption Price, interest or premium, if any, the Payor or the relevant Guarantor, as applicable, will pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by the Holders of the Notes or the Trustee, as the case may be, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), equal the amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no such Additional Amounts will be payable with respect to:

(1)       any Taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction upon any payments to a Holder or Beneficial Owner who is liable for such Taxes in respect of the Notes by reason of the Holder (or a fiduciary, settlor, beneficiary, member, partner or shareholder of, or possessor of power over the relevant Holder, if the relevant Holder is an estate, nominee, trust, partnership, limited liability company or corporation) or Beneficial Owner having any present or former connection with such Relevant Taxing Jurisdiction (including, without limitation, being resident for tax purposes, being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Relevant Taxing Jurisdiction) other than a connection arising from the acquisition, ownership or holding of such Note or enforcement of rights thereunder or the receipt of payments in respect of the Notes or with respect to any Guarantee;

A-4

(2)       any Taxes that would not have been imposed if the Holder or Beneficial Owner had made a declaration of non-residence or any other claim or filing for exemption to which it is entitled (provided that (x) such declaration of non-residence or other claim or filing for exemption is required by the applicable law of the applicable Relevant Taxing Jurisdiction as a precondition to exemption from the requirement to deduct or withhold such Taxes and (y) at least 30 days prior to the first payment date with respect to which such declaration of non-residence or other claim or filing for exemption is required under the applicable law of the applicable Relevant Taxing Jurisdiction, the relevant Holder or Beneficial Owner at that time has been notified in writing by the Payor or any other person through whom payment may be made that a declaration of non-residence or other claim or filing for exemption is required to be made);

(3)       except in the case of the winding up of the Payor, any Note presented for payment (where presentation is required) in the Relevant Taxing Jurisdiction (unless by reason of the Payor’s actions, presentment could not have been made elsewhere and except to the extent that the Holder would have been entitled to Additional Amounts had the Notes been presented elsewhere);

(4)       any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented during such 30 day period);

(5)       any Taxes that are payable otherwise than by withholding from a payment of the principal of, premium, if any, or interest, if any, on the Notes or with respect to any Guarantee;

Upon request, the Issuer will provide the Trustee with documentation satisfactory to the Trustee evidencing the payment of Additional Amounts. Copies of such documentation will be made available to the Holders upon request.

4.       Paying Agent, Registrar and Transfer Agent. Initially, Deutsche Bank Trust Company Americas will act as Paying Agent, Registrar and Transfer Agent. In the event that a Paying Agent or Transfer Agent is replaced, the Issuer will provide notice thereof as set forth in the Indenture. The Issuer may change any Registrar without notice to the Holders. The Issuer or any of its Subsidiaries may, subject to certain exceptions, act in any such capacity.

5.       Indenture. The Issuer issued the Notes under a base indenture, dated as of November 21, 2025 (the “Base Indenture”), as supplemented by an Officers’ Certificate, dated November 24, 2025, pursuant to Sections 2.1 and 12.4 of the Base Indenture (together with the Base Indenture, the “Indenture”), establishing certain terms of the Notes, among the Issuer, the Guarantors and Deutsche Bank Trust Company Americas, as Trustee, Paying Agent, Transfer Agent and Registrar. This Note is one of a duly authorized issue of Notes of the Issuer designated as its 3.489% Senior Notes due 2031 (the “Notes”). The terms of the Notes include those stated in the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture for a statement of them. The Notes are senior obligations of the Issuer. Additional Notes may be issued from time to time under the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time.

6.       Ranking. The Notes will be senior unsecured obligations of the Issuer and will: (a) rank equally in right of payment with all of the Issuer’s existing and future Indebtedness that is not subordinated in right of payment to the Notes; (b) rank senior in right of payment to all of the Issuer’s existing and future Indebtedness that is subordinated in right of payment to the Notes; (c) be effectively junior to all of the Issuer’s existing and future secured Indebtedness to the extent of the value of the collateral securing such other Indebtedness; and (d) be structurally subordinated in right of payment to any obligations of Smurfit Westrock’s Subsidiaries other than Smurfit Westrock’s Subsidiaries that are Guarantors.

7.       Optional Redemption. Except as set forth below in this Paragraph 7 or under Paragraph 8, none of the Notes will be redeemable prior to August 24, 2031.

Prior to August 24, 2031 (the date that is three months prior to the scheduled maturity of the Notes) (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 (a) 100% of the principal amount of the Notes to be redeemed and (b) (i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed are scheduled to mature on the Par Call Date) on an annual basis (ACTUAL/ACTUAL (ICMA)) at the Comparable Government Bond Rate plus 20 basis points, less (ii) interest accrued to the date of redemption, plus, in either case, accrued and unpaid interest thereon and Additional Amounts, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Amounts, if any, thereon, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, any redemption price shall be calculated by the Issuer, or on behalf of the Issuer by such Person as the Issuer may engage, and the calculation of the redemption price shall not be an obligation or duty of the Trustee or the Paying Agent. Neither the Trustee nor any Paying Agent shall be responsible for determining or verifying the Company’s determination of the redemption price.

A-6

Any such redemption and notice may, in the Issuer’s discretion, be subject to the satisfaction of one or more conditions precedent, and such notice may state that, in the Issuer’s discretion, the Redemption Date may be delayed without any additional notice until such time as any or all such conditions shall be satisfied.

In the case of a partial redemption of the Notes, selection of the Notes to be redeemed shall be made in the manner described in Section 3.3 of the Indenture.

If and for so long as the Notes to be redeemed are admitted to the Global Exchange Market of Euronext Dublin and the rules of Euronext Dublin so require, not less than 10 nor more than 60 days prior to the Redemption Date, the Issuer will mail notice of redemption to Holders by first class mail, postage prepaid, or otherwise in accordance with the applicable procedures of Euroclear or Clearstream, to each Holder of Notes to be redeemed, at such Holder’s address appearing in the Register. Such notice of redemption may also be posted on the official website of Euronext Dublin (www.ise.ie), to the extent and in the manner permitted by the rules of Euronext Dublin.

In connection with this Paragraph 7, the following defined terms apply:

Comparable GovernmentBond” means, in relation to any Comparable Government Bond Rate calculation, at the Issuer’s discretion, a German government bond whose maturity is closest to the maturity of the Notes being redeemed, or if the Issuer determines that such similar bond is not in issue, such other German government bond as the Issuer 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 GovernmentBond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the applicable Comparable Government Bond on the basis of the middle market price of such Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by the Issuer.

8.       Special Tax Redemption. The Issuer may, at its option, redeem the Notes in whole, but not in part, at any time upon giving not less than 10 nor more than 60 days’ notice to the Holders of the Notes (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption (a “Tax Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if a Payor determines that, as a result of: (1) any change in, or amendment to, the law or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation or (2) any change in position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) (each of the foregoing in clauses (1) and (2), a “Change in TaxLaw”), the Payor or any Guarantor is, or on the next interest payment date in respect of the Notes would be, required to pay Additional Amounts with respect to the Notes, and the Payor or the relevant Guarantor (as appropriate) cannot avoid such obligation by taking reasonable measures available to it. In the case of the Issuer or any Guarantor as of the original issue date of the Notes, the Change in Tax Law must become effective on or after the original issue date of the Notes. In the case of a Successor Issuer or any Person who becomes a Guarantor after the original issue date of the Notes or any successor of any Guarantor, the Change in Tax Law must become effective after the date that the Issuer first makes payment on the Notes or after the date on which such Person became a Guarantor or a successor of any Guarantor, as applicable. Notice of redemption for taxation reasons will be published in accordance with the procedures set forth in the Indenture. Notwithstanding the foregoing, no such notice of redemption will be given earlier than 90 days prior to the earliest date on which the Payor or Guarantor, as applicable, would be obligated to make such payment or withholding if a payment in respect of the Notes were then due. Prior to the publication or mailing of any notice of redemption of the Notes pursuant to the foregoing, the Payor will deliver to the Trustee an opinion of an independent tax counsel reasonably satisfactory to the Trustee to the effect that the circumstances referred to above exist. The Trustee will accept such opinion as sufficient existence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders of the Notes.

A-7

9.       Guarantees. The payment by the Issuer of the principal of, premium, if any, interest and Additional Amounts, if any, on the Notes and all other obligations of the Issuer under the Indenture is, subject to Section 11.2 of the Indenture and limitations under applicable law, fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by each of the Guarantors to the extent set forth in the Indenture.

10.       Denominations; Form; Transfer and Exchange. The Global Notes are in registered form, without coupons, in denominations of €100,000 and integral multiples of €1,000 in excess thereof.

12.       Unclaimed Funds. If funds for the payment of principal of, premium, if any, interest and Additional Amounts, if any, on the Notes remain unclaimed for two years, the Trustee and the Paying Agents will repay the funds to the Issuer at its written request. After that, all liability of the Trustee and such Paying Agents with respect to such funds shall cease.

13.       Legal Defeasance and Covenant Defeasance. The Issuer may be discharged from its obligations under the Indenture and the Notes except for certain provisions thereof, and may be discharged from its obligations to comply with certain covenants contained in the Indenture, in each case upon satisfaction of certain conditions specified in the Indenture.

14.       Amendment; Supplement; Waiver. Subject to certain exceptions specified in the Indenture, the Indenture, the Notes or the Guarantees may be amended or supplemented with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding.

15.       Successors. When a successor assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

16.       Defaults and Remedies. Subject to certain restrictions, if an Event of Default (other than an Event of Default specified in clause (4) of Section 7.1 of the Base Indenture) occurs and is continuing with respect to the Notes, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, interest, and Additional Amounts, if any, including an accelerated payment) if it determines that withholding notice is in their interest.

17.       Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

18.       No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

Interest on the Notes will be payable annually in arrears on November 24 of each year, commencing November 24, 2026. The Issuer will make each interest payment to the Holders of record at the close of business on the immediately preceding November 10. Rights of holders of beneficial interests to receive such payments will be subject to applicable procedures of Euroclear or Clearstream. Interest on the Notes will accrue at the rate of 3.489% per annum on the aggregate nominal amount of the Notes outstanding. Interest accruing on all Notes then outstanding shall be payable in cash. Interest on the Notes will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid or duly provided for on the Notes (or the date of original issuance 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 Market Association.

Any interest paid on this Note shall be increased to the extent necessary to pay Additional Amounts as set forth herein.

2.       Additional Amounts. All payments made by the Payor on the Notes or any Guarantor with respect to its Guarantee will be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature (“Taxes”) imposed or levied by or on behalf of (1) any jurisdiction in which the Payor or any Guarantor or successor Guarantor is organized or otherwise considered resident for tax purposes or any political subdivision or governmental authority thereof or therein having power to tax, or (2) any jurisdiction from or through which payment on the Notes or any of the Guarantees is made, or any political subdivision or governmental authority thereof or therein having the power to tax (each of clause (1) and (2), a “Relevant Taxing Jurisdiction”), unless the withholding or deduction of such Taxes is then required by law. If any deduction or withholding for, or on account of, any Taxes of any Relevant Taxing Jurisdiction shall at any time be required from any payments made with respect to the Notes or the Guarantees, including, without limitation, payments of principal, Redemption Price, interest or premium, if any, the Payor or the relevant Guarantor, as applicable, will pay (together with such payments) such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received in respect of such payments by the Holders of the Notes or the Trustee, as the case may be, after such withholding or deduction (including any such deduction or withholding from such Additional Amounts), equal the amounts which would have been received in respect of such payments in the absence of such withholding or deduction; provided, however, that no such Additional Amounts will be payable with respect to:

(1)       any Taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction upon any payments to a Holder or Beneficial Owner who is liable for such Taxes in respect of the Notes by reason of the Holder (or a fiduciary, settlor, beneficiary, member, partner or shareholder of, or possessor of power over the relevant Holder, if the relevant Holder is an estate, nominee, trust, partnership, limited liability company or corporation) or Beneficial Owner having any present or former connection with such Relevant Taxing Jurisdiction (including, without limitation, being resident for tax purposes, being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Relevant Taxing Jurisdiction) other than a connection arising from the acquisition, ownership or holding of such Note or enforcement of rights thereunder or the receipt of payments in respect of the Notes or with respect to any Guarantee;

(2)       any Taxes that would not have been imposed if the Holder or Beneficial Owner had made a declaration of non-residence or any other claim or filing for exemption to which it is entitled (provided that (x) such declaration of non-residence or other claim or filing for exemption is required by the applicable law of the applicable Relevant Taxing Jurisdiction as a precondition to exemption from the requirement to deduct or withhold such Taxes and (y) at least 30 days prior to the first payment date with respect to which such declaration of non-residence or other claim or filing for exemption is required under the applicable law of the applicable Relevant Taxing Jurisdiction, the relevant Holder or Beneficial Owner at that time has been notified in writing by the Payor or any other person through whom payment may be made that a declaration of non-residence or other claim or filing for exemption is required to be made);

B-5

(3)       except in the case of the winding up of the Payor, any Note presented for payment (where presentation is required) in the Relevant Taxing Jurisdiction (unless by reason of the Payor’s actions, presentment could not have been made elsewhere and except to the extent that the Holder would have been entitled to Additional Amounts had the Notes been presented elsewhere);

(4)       any Note presented for payment (where presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder would have been entitled to Additional Amounts had the Note been presented during such 30 day period);

(5)       any Taxes that are payable otherwise than by withholding from a payment of the principal of, premium, if any, or interest, if any, on the Notes or with respect to any Guarantee;

(6)       any estate, inheritance, gift, sales, excise, transfer, personal property or similar tax, assessment or other governmental charge;

(7)       a Tax imposed in connection with a Note presented for payment by or on behalf of a Holder or Beneficial Owner who would have been able to avoid such Tax by presenting the Note to, or otherwise accept payment from, another paying agent in a member state of the European Union;

(8)       any Taxes imposed, deducted or withheld pursuant to Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code, in each case, as of the Original Issue Date (and any amended or successor version that is substantively comparable); any current or future regulations or agreements thereunder, official interpretations thereof or any law implementing an intergovernmental agreement relating thereto; or any treaty, law, regulation or other official guidance enacted in any other jurisdiction, facilitating implementation thereof;

(9)       all United States backup withholding taxes;

(10)     any Tax deducted, withheld or imposed in connection with the Dutch Withholding Tax Act 2021 (Wet bronbelasting 2021), as amended from time to time; or

Such Additional Amounts will also not be payable where, had the Beneficial Owner of the Note been the Holder of the Note, it would not have been entitled to payment of Additional Amounts by reason of clauses (1) to (11) inclusive above.

Upon request, the Issuer will provide the Trustee with documentation satisfactory to the Trustee evidencing the payment of Additional Amounts. Copies of such documentation will be made available to the Holders upon request.

Any such redemption and notice may, in the Issuer’s discretion, be subject to the satisfaction of one or more conditions precedent, and such notice may state that, in the Issuer’s discretion, the Redemption Date may be delayed without any additional notice until such time as any or all such conditions shall be satisfied.

In the case of a partial redemption of the Notes, selection of the Notes to be redeemed shall be made in the manner described in Section 3.3 of the Indenture.

If and for so long as the Notes to be redeemed are admitted to the Global Exchange Market of Euronext Dublin and the rules of Euronext Dublin so require, not less than 10 nor more than 60 days prior to the Redemption Date, the Issuer will mail notice of redemption to Holders by first class mail, postage prepaid, or otherwise in accordance with the applicable procedures of Euroclear or Clearstream, to each Holder of Notes to be redeemed, at such Holder’s address appearing in the Register. Such notice of redemption may also be posted on the official website of Euronext Dublin (www.ise.ie), to the extent and in the manner permitted by the rules of Euronext Dublin.

In connection with this Paragraph 7, the following defined terms apply:

Comparable GovernmentBond” means, in relation to any Comparable Government Bond Rate calculation, at the Issuer’s discretion, a German government bond whose maturity is closest to the maturity of the Notes being redeemed, or if the Issuer determines that such similar bond is not in issue, such other German government bond as the Issuer 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 GovernmentBond Rate” means the yield to maturity, expressed as a percentage (rounded to three decimal places, 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, of the applicable Comparable Government Bond on the basis of the middle market price of such Comparable Government Bond prevailing at 11:00 a.m. (London time) on such Business Day as determined by the Issuer.

8.       Special Tax Redemption. The Issuer may, at its option, redeem the Notes in whole, but not in part, at any time upon giving not less than 10 nor more than 60 days’ notice to the Holders of the Notes (which notice will be irrevocable) at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to, but excluding, the date fixed for redemption (a “Tax Redemption Date”) (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), and all Additional Amounts, if any, then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if a Payor determines that, as a result of: (1) any change in, or amendment to, the law or treaties (or any regulations or rulings promulgated thereunder) of a Relevant Taxing Jurisdiction affecting taxation or (2) any change in position regarding the application, administration or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction) (each of the foregoing in clauses (1) and (2), a “Change in TaxLaw”), the Payor or any Guarantor is, or on the next interest payment date in respect of the Notes would be, required to pay Additional Amounts with respect to the Notes, and the Payor or the relevant Guarantor (as appropriate) cannot avoid such obligation by taking reasonable measures available to it. In the case of the Issuer or any Guarantor as of the original issue date of the Notes, the Change in Tax Law must become effective on or after the original issue date of the Notes. In the case of a Successor Issuer or any Person who becomes a Guarantor after the original issue date of the Notes or any successor of any Guarantor, the Change in Tax Law must become effective after the date that the Issuer first makes payment on the Notes or after the date on which such Person became a Guarantor or a successor of any Guarantor, as applicable. Notice of redemption for taxation reasons will be published in accordance with the procedures set forth in the Indenture. Notwithstanding the foregoing, no such notice of redemption will be given earlier than 90 days prior to the earliest date on which the Payor or Guarantor, as applicable, would be obligated to make such payment or withholding if a payment in respect of the Notes were then due. Prior to the publication or mailing of any notice of redemption of the Notes pursuant to the foregoing, the Payor will deliver to the Trustee an opinion of an independent tax counsel reasonably satisfactory to the Trustee to the effect that the circumstances referred to above exist. The Trustee will accept such opinion as sufficient existence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders of the Notes.

B-8

9.       Guarantees. The payment by the Issuer of the principal of, premium, if any, interest or Additional Amounts, if any, on the Notes and all other obligations of the Issuer under the Indenture is, subject to Section 11.2 of the Indenture and limitations under applicable law, fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis, by each of the Guarantors to the extent set forth in the Indenture.

10.       Denominations; Form; Transfer and Exchange. The Notes are in definitive registered form, without coupons, in denominations of €100,000 and integral multiples of €1,000 in excess thereof. The Trustee, the Registrar, the Paying Agent and the Transfer Agent may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay all taxes and fees required by law or permitted by the Indenture.

11.       Persons Deemed Owners. The registered Holder of this Note shall be treated as the owner of it for all purposes, subject to the terms of the Indenture.

12.       Unclaimed Funds. If funds for the payment of principal of, premium, if any, interest and Additional Amounts, if any, on the Notes remain unclaimed for two years, the Trustee and the Paying Agents will repay the funds to the Issuer at its written request. After that, all liability of the Trustee and such Paying Agents with respect to such funds shall cease.

13.       Legal Defeasance and Covenant Defeasance. The Issuer may be discharged from its obligations under the Indenture and the Notes except for certain provisions thereof, and may be discharged from its obligations to comply with certain covenants contained in the Indenture, in each case upon satisfaction of certain conditions specified in the Indenture.

14.       Amendment; Supplement; Waiver. Subject to certain exceptions specified in the Indenture, the Indenture, the Notes or the Guarantees may be amended or supplemented with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding.

15.       Successors. When a successor assumes all the obligations of its predecessor under the Notes and the Indenture in accordance with the terms of the Indenture, the predecessor will be released from those obligations.

16.       Defaults and Remedies. Subject to certain restrictions, if an Event of Default (other than an Event of Default specified in clause (4) of Section 7.1 of the Base Indenture) occurs and is continuing with respect to the Notes, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal, premium, interest, and Additional Amounts, if any, including an accelerated payment) if it determines that withholding notice is in their interest.

17.       Trustee Dealings with Issuer. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer, its Subsidiaries or their respective Affiliates as if it were not the Trustee.

18.       No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or any Guarantor under the Notes, the Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

For purposes of this opinion letter, we have assumed that (i) each party to the Indenture, other than the Covered Guarantors, has all requisite power and authority under all applicable laws, regulations and governing documents to execute, deliver and perform its obligations under the Indenture and has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Indenture against the other parties thereto, (ii) each party to the Indenture, other than the Covered Guarantors, has duly authorized, executed and delivered the Indenture, (iii) each party to the Indenture, other than the Covered Guarantors, is validly existing and in good standing in all necessary jurisdictions, (iv) the Indenture constitutes a valid and binding obligation, enforceable against the Trustee in accordance with its terms, (v) there has been no mutual mistake of fact or misunderstanding or fraud, duress or undue influence in connection with the negotiation, execution or delivery of the Indenture, and the conduct of all parties to the Indenture has complied with any requirements of good faith, fair dealing and conscionability, (vi) at the time of offer, issuance and sale of any Securities, no stop order suspending the effectiveness of the Registration Statement will have been issued and remain in effect and (vii) there are and have been no agreements or understandings among the parties, written or oral, and there is and has been no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of the Indenture. We have also assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

This opinion letter is based as to matters of law solely on the applicable provisions of the following, as currently in effect: (i) the General Corporation Law of the State of Delaware, as amended, and the Delaware Limited Liability Company Act, as amended, and (ii) the laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level). We express no opinion herein as to any other statutes, rules or regulations (and in particular, we express no opinion as to any effect that such other statutes, rules or regulations may have on the opinions expressed herein).

Based upon, subject to and limited by the foregoing, we are of the opinion that (a) the Guarantees have been duly authorized on behalf of the Covered Guarantors and that, following (i) receipt by the Issuer and the Guarantors of the consideration for the Securities specified in the Agreement and (ii) the due execution, authentication, issuance and delivery of the Securities pursuant to the terms of the Indenture, (b) the Securities will constitute valid and binding obligations of the Issuer and the Guarantors.

The opinion expressed above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights and remedies (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances and fraudulent, preferential or voidable transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the Securities are considered in a proceeding in equity or at law), including, without limitation, principles limiting the availability of specific performance and injunctive relief.

SCHEDULE 3

Qualifications

The opinions in paragraph 2 of this legal opinion are made subject to the following qualifications:

Limitations of Searches

1. For the purpose of giving this legal opinion, we have relied solely on the Searches. The records held<br>by the Companies Registration Office and/or the High Court may not necessarily be up to date or relevant filings may not have been made<br>and, as a consequence, this may affect the results or accuracy of any searches made in those offices. It is not possible to search the<br>records held by the Circuit Court.

Limitations arising from Insolvency Law

2. This legal opinion is subject to all applicable laws on bankruptcy, insolvency, liquidation, receivership,<br>court protections including examinership, reorganisation, court schemes, moratoria, stabilisation, resolution, trust schemes, preferential<br>creditors, fraudulent disposition, improper transfer, unfair preference and other laws relating to or affecting creditors' rights generally.

Sanctions

3. If a party to any Document is, or any payment under a Document is made to, by or in respect of a person<br>resident, located or incorporated in a country that is subject to sanctions recognised or imposed by Ireland or is controlled by or connected<br>to a person resident, located or incorporated in a country that is subject to sanctions recognised or imposed by Ireland, then the obligations<br>of that party or obligations to that party under the relevant Document may be unenforceable or void. We have made no investigation as<br>to which sanctions may affect the Transaction at the date of this legal opinion.

Execution of Documents

4. Judicial opinion in the English case of R (on the application of Mercury Tax Group Limited and Another)<br>v. HMRC 2008 EWHC 2721 appears to indicate that if a previously executed signature page from a draft version of a document is transferred<br>to the final version of that document, such document may not be validly executed, notwithstanding that the parties authorised it. While<br>decisions of the English courts are not binding on the Irish courts, they may have persuasive authority, and it is possible that an Irish<br>court might hold a document whose executed signature pages have been transferred between versions to be invalidly executed.

Enforcement and Binding Effect

5. The description of obligations in this legal opinion as "enforceable" refers to the legal character<br>of the obligations assumed by the relevant party under the relevant instrument. It implies no more than the obligations are of a character<br>which the laws of Ireland recognise and will in certain circumstances enforce. In particular, it does not mean or imply that the relevant<br>instrument will be enforced in all circumstances in accordance with its terms or by or against third parties or that any particular remedy<br>will be available. In particular (without limiting the foregoing):
5.1 the binding effect and enforceability of the obligations of the Guarantors and the Issuers contemplated<br>under the Guarantees or any of the Securities may be limited by liquidation, insolvency, bankruptcy, receivership, court protection, examinership,<br>moratoria, reorganisation, reconstruction, company volunteer arrangements, fraud of creditors, fraudulent preference of creditors or similar<br>laws whether in Ireland or elsewhere affecting creditors' rights generally;
--- ---
5.2 the binding effect and enforceability of the obligations of the Guarantors and the Issuers under the Guarantees<br>or any of the Securities may also be limited as a result of the provisions of the laws of Ireland applicable to contracts held to have<br>become frustrated by events happening after their execution, and any breach of the terms of any document by the party seeking to enforce<br>such document;
--- ---
5.3 enforcement may be limited by general principles of equity. In particular, equitable remedies are not<br>available where damages are considered to be an adequate remedy; the remedy of specific performance is discretionary and will not normally<br>be ordered in respect of a monetary obligation; and injunctions are granted only on a discretionary basis and accordingly we express no<br>opinion on such matters;
--- ---
5.4 claims may become barred under the Statute of Limitations 1957 or may be or become subject to the defence<br>of set-off or counterclaim;
--- ---
5.5 enforcement will be subject to, netting, claims and attachment and any other rights of another party to<br>a contract; and
--- ---
5.6 enforcement may be limited by reason of fraud.
--- ---
6. Where any obligations of any person are to be performed in jurisdictions outside Ireland, such obligations<br>may not be enforceable under Irish law to the extent that performance thereof would be illegal under the laws of any such jurisdiction<br>or contrary to public policy under the laws of any such jurisdiction and an Irish court may take into account the law of the place of<br>performance in relation to the manner of performance and to the steps to be taken in the event of defective performance.
--- ---
7. Where a judgment creditor seeks to enforce his judgment, he can only do so in accordance with the applicable<br>rules of Irish courts. The making of an execution order against particular assets, such as a charging order over land or a beneficial<br>interest therein or most types of investment or a third party debt order over a bank account or certain other debts, is a matter for the<br>Court's discretion.
--- ---
8. Provisions (including but not limited to provisions for default interest) imposing additional payment<br>obligations in the event of breach or default or late payment, to the extent they do not represent a genuine pre-estimate of loss of the<br>aggrieved party, may be held to be unenforceable on the grounds that it is a penalty or in the nature of a penalty.
--- ---

9. Where a party to a Document has a discretion or may determine a matter in its opinion, an Irish court<br>may require that such discretion is exercised reasonably and in good faith and that such determination is made in good faith based on<br>reasonable grounds.
10. Any provision in any Document providing for the conclusiveness and binding effect of any calculation,<br>determination or certificate may be held by an Irish court not to be final, conclusive or binding, notwithstanding any provision in any<br>Document to the contrary, if it is shown to have an unreasonable or arbitrary basis or not to have been reached in good faith.
--- ---
11. A waiver of any defences to any proceedings may not be enforceable.
--- ---
12. Any provision in a Document providing for a matter to be agreed in the future may be unenforceable or<br>void for uncertainty.
--- ---
13. An Irish court has discretion on whether or not to enforce any provision in any of the Documents providing<br>for severance of provisions in the event of illegality, invalidity or unenforceability.
--- ---

No Waivers

14. Any provision in a Document stating that a failure or delay in exercising any right or remedy under the<br>Document shall not operate as a waiver of such right or remedy may not be effective.

Indemnity for Costs Provisions

15. An Irish court may refuse to give effect to any provision of an agreement which amounts to an indemnity<br>in respect of the costs of unsuccessful litigation brought before an Irish court or where the court has itself made an order for costs.

Limitation on Liability

16. The effectiveness of any provision in any of the Documents purporting to exculpate a party from a liability,<br>obligation or duty otherwise owed is limited by Irish law.

Judgments in Non-Euro Currencies

17. Any judgment of the Irish courts for monies due under any Document may be expressed in a currency other<br>than euro but the order may issue out of the Central Office of the Irish High Court expressed in euro by reference to the official rate<br>of exchange prevailing on the date of issue. In addition, in a winding-up in Ireland of an Irish incorporated company, all foreign currency<br>claims must be converted into euro for the purposes of proof. The rate of exchange to be used to convert foreign currency debts into euro<br>for the purpose of proof in a winding-up is the spot rate (in the case of a compulsory winding-up) on the date of the winding-up order<br>and (in the case of a voluntary winding-up) on the date of the relevant winding-up resolution.

Power of Court to Stay Actions

18. An Irish court may (or, in certain cases, must) strike out or stay an action if concurrent proceedings<br>are being brought elsewhere and may or must decline to accept jurisdiction in certain cases.

SCHEDULE 3

Qualifications

The opinions in paragraph 2 of this legal opinion are made subject to the following qualifications:

Limitations of Searches

1. For the purpose of giving this legal opinion, we have relied solely on the Searches. The records held<br>by the Companies Registration Office and/or the High Court may not necessarily be up to date or relevant filings may not have been made<br>and, as a consequence, this may affect the results or accuracy of any searches made in those offices. It is not possible to search the<br>records held by the Circuit Court.

Limitations arising from Insolvency Law

2. This legal opinion is subject to all applicable laws on bankruptcy, insolvency, liquidation, receivership,<br>court protections including examinership, reorganisation, court schemes, moratoria, stabilisation, resolution, trust schemes, preferential<br>creditors, fraudulent disposition, improper transfer, unfair preference and other laws relating to or affecting creditors' rights generally.

Sanctions

3. If a party to any Document is, or any payment under a Document is made to, by or in respect of a person<br>resident, located or incorporated in a country that is subject to sanctions recognised or imposed by Ireland or is controlled by or connected<br>to a person resident, located or incorporated in a country that is subject to sanctions recognised or imposed by Ireland, then the obligations<br>of that party or obligations to that party under the relevant Document may be unenforceable or void. We have made no investigation as<br>to which sanctions may affect the Transaction at the date of this legal opinion.

Execution of Documents

4. Judicial opinion in the English case of R (on the application of Mercury Tax Group Limited and Another)<br>v. HMRC 2008 EWHC 2721 appears to indicate that if a previously executed signature page from a draft version of a document is transferred<br>to the final version of that document, such document may not be validly executed, notwithstanding that the parties authorised it. While<br>decisions of the English courts are not binding on the Irish courts, they may have persuasive authority, and it is possible that an Irish<br>court might hold a document whose executed signature pages have been transferred between versions to be invalidly executed.

Enforcement and Binding Effect

5. The description of obligations in this legal opinion as "enforceable" refers to the legal character<br>of the obligations assumed by the relevant party under the relevant instrument. It implies no more than the obligations are of a character<br>which the laws of Ireland recognise and will in certain circumstances enforce. In particular, it does not mean or imply that the relevant<br>instrument will be enforced in all circumstances in accordance with its terms or by or against third parties or that any particular remedy<br>will be available. In particular (without limiting the foregoing):
5.1 the binding effect and enforceability of the obligations of the Guarantors and the Issuers contemplated<br>under the Guarantees or any of the Securities may be limited by liquidation, insolvency, bankruptcy, receivership, court protection, examinership,<br>moratoria, reorganisation, reconstruction, company volunteer arrangements, fraud of creditors, fraudulent preference of creditors or similar<br>laws whether in Ireland or elsewhere affecting creditors' rights generally;
--- ---
5.2 the binding effect and enforceability of the obligations of the Guarantors and the Issuers under the Guarantees<br>or any of the Securities may also be limited as a result of the provisions of the laws of Ireland applicable to contracts held to have<br>become frustrated by events happening after their execution, and any breach of the terms of any document by the party seeking to enforce<br>such document;
--- ---
5.3 enforcement may be limited by general principles of equity. In particular, equitable remedies are not<br>available where damages are considered to be an adequate remedy; the remedy of specific performance is discretionary and will not normally<br>be ordered in respect of a monetary obligation; and injunctions are granted only on a discretionary basis and accordingly we express no<br>opinion on such matters;
--- ---
5.4 claims may become barred under the Statute of Limitations 1957 or may be or become subject to the defence<br>of set-off or counterclaim;
--- ---
5.5 enforcement will be subject to, netting, claims and attachment and any other rights of another party to<br>a contract; and
--- ---
5.6 enforcement may be limited by reason of fraud.
--- ---
6. Where any obligations of any person are to be performed in jurisdictions outside Ireland, such obligations<br>may not be enforceable under Irish law to the extent that performance thereof would be illegal under the laws of any such jurisdiction<br>or contrary to public policy under the laws of any such jurisdiction and an Irish court may take into account the law of the place of<br>performance in relation to the manner of performance and to the steps to be taken in the event of defective performance.
--- ---
7. Where a judgment creditor seeks to enforce his judgment, he can only do so in accordance with the applicable<br>rules of Irish courts. The making of an execution order against particular assets, such as a charging order over land or a beneficial<br>interest therein or most types of investment or a third party debt order over a bank account or certain other debts, is a matter for the<br>Court's discretion.
--- ---

8. Provisions (including but not limited to provisions for default interest) imposing additional payment<br>obligations in the event of breach or default or late payment, to the extent they do not represent a genuine pre-estimate of loss of the<br>aggrieved party, may be held to be unenforceable on the grounds that it is a penalty or in the nature of a penalty.
9. Where a party to a Document has a discretion or may determine a matter in its opinion, an Irish court<br>may require that such discretion is exercised reasonably and in good faith and that such determination is made in good faith based on<br>reasonable grounds.
--- ---
10. Any provision in any Document providing for the conclusiveness and binding effect of any calculation,<br>determination or certificate may be held by an Irish court not to be final, conclusive or binding, notwithstanding any provision in any<br>Document to the contrary, if it is shown to have an unreasonable or arbitrary basis or not to have been reached in good faith.
--- ---
11. A waiver of any defences to any proceedings may not be enforceable.
--- ---
12. Any provision in a Document providing for a matter to be agreed in the future may be unenforceable or<br>void for uncertainty.
--- ---
13. An Irish court has discretion on whether or not to enforce any provision in any of the Documents providing<br>for severance of provisions in the event of illegality, invalidity or unenforceability.
--- ---

No Waivers

14. Any provision in a Document stating that a failure or delay in exercising any right or remedy under the<br>Document shall not operate as a waiver of such right or remedy may not be effective.

Indemnity for Costs Provisions

15. An Irish court may refuse to give effect to any provision of an agreement which amounts to an indemnity<br>in respect of the costs of unsuccessful litigation brought before an Irish court or where the court has itself made an order for costs.

Limitation on Liability

16. The effectiveness of any provision in any of the Documents purporting to exculpate a party from a liability,<br>obligation or duty otherwise owed is limited by Irish law.

Judgments in Non-Euro Currencies

17. Any judgment of the Irish courts for monies due under any Document may be expressed in a currency other<br>than euro but the order may issue out of the Central Office of the Irish High Court expressed in euro by reference to the official rate<br>of exchange prevailing on the date of issue. In addition, in a winding-up in Ireland of an Irish incorporated company, all foreign currency<br>claims must be converted into euro for the purposes of proof. The rate of exchange to be used to convert foreign currency debts into euro<br>for the purpose of proof in a winding-up is the spot rate (in the case of a compulsory winding-up) on the date of the winding-up order<br>and (in the case of a voluntary winding-up) on the date of the relevant winding-up resolution.

Power of Court to Stay Actions

18. An Irish court may (or, in certain cases, must) strike out or stay an action if concurrent proceedings<br>are being brought elsewhere and may or must decline to accept jurisdiction in certain cases.

(4) In rendering this opinion we have assumed:
(a) the genuineness and authenticity of all signatures on, and the authenticity and completeness of, all documents<br>submitted to us as copies of drafts, originals or execution copies and the exact conformity to the originals of all documents submitted<br>to us as photocopies or copies transmitted by facsimile or by electronic means;

--- ---
(c) (i) the power, capacity and authority of all parties thereto other than the Company to enter into<br>and execute the Indenture; (ii) that the Indenture has been duly authorised by all parties thereto other than the Company, (iii) that<br>the Indenture has been validly executed and delivered (where such concept is legally relevant) by each of the parties thereto (other than<br>the Company) under all applicable laws, including the laws by which the Indenture is expressed to be governed and (iv) that the Indenture<br>has been validly executed and delivered (where such concept is legally relevant) by the Company under all applicable laws, including the<br>laws by which the Indenture is expressed to be governed, other than the laws of the Netherlands;
--- ---
(d) that any and all authorisations and consents of, or other filings with or notifications to, any public<br>authority or other relevant body or person in or of any jurisdiction which may be required (other than under the laws of the Netherlands)<br>in respect of the execution or performance of the Documents have been or will be duly obtained or made, as the case may be;
--- ---
2

(e) that the choice of the laws of the State of New York to govern the Indenture is valid under such laws<br>and under the laws of any other applicable jurisdiction other than the Netherlands and would be recognised and given effect to by any<br>U.S. Federal or New York State court in the Borough of Manhattan in the City, County and State of New York, United States of America and<br>the courts of any other jurisdiction other than the Netherlands;
(f) that the Indenture constitutes legal, valid and binding obligations of the parties thereto and is enforceable<br>in accordance with its terms under all applicable laws, including the laws of the State of New York by which the Indenture is expressed<br>to be governed, other than the laws of the Netherlands;
--- ---
(g) that the information set forth in the Extract is complete and accurate on the date hereof and consistent<br>with the information contained in the files kept by the Trade Register with respect to the Company;
--- ---
(h) that all matters stated in the Resolutions and the confirmations given therein are correct on the date<br>hereof, and that the Resolutions have not been annulled, revoked or rescinded and are in full force and effect as at the date hereof and<br>that there is no law of a jurisdiction other than the Netherlands applicable under the 1978 Hague Convention on the Law applicable to<br>Agency which adversely affects the existence or extent of the authority expressed to be granted in any power of attorney;
--- ---
(i) that the Company has not been declared bankrupt (failliet verklaard), granted suspension of payments<br>(surseance van betaling verleend) or dissolved (ontbonden), nor has ceased to exist due to merger (fusie) or demerger<br>(splitsing) and that no out of court restructuring plan (onderhands akkoord) procedure is being prepared or has been commenced<br>involving the Company; although not constituting conclusive evidence, this assumption is supported by the contents of the Extract and<br>by our online search of the Central Insolvency Register of the courts of the Netherlands (Centraal Insolventieregister) (as regards<br>the out of court restructuring plan (onderhands akkoord) procedure, a search can be performed with respect to a public procedure<br>only) on the date hereof, which did not reveal any information which would render this assumption to be untrue;
--- ---
(j) that none of the insolvency proceedings listed in Annex A, as amended, to Regulation (EU) 2015/848 of<br>the European Parliament and of the Council of 20 May 2015 on insolvency proceedings (recast) has been declared applicable to the<br>Company by a court in one of the member states of the EU (with the exception of Denmark); although not constituting conclusive evidence,<br>this assumption is supported by our online search of the section on EU Registrations of the Central Insolvency Register (Centraal Insolventieregister)<br>on the date hereof, which did not reveal any information which would render this assumption to be untrue;
--- ---
(k) that, to the extent any of the provisions of the Indenture constitutes an irrevocable power of attorney<br>granted by the Company within the meaning of section 3:74 of the Civil Code, such power of attorney aims at the performance of a legal<br>act (strekt tot het verrichten van een rechtshandeling) in the interest of the proxy or a third party;
--- ---
3

(l) that none of the members of the managing board of the Company has a conflict of interests within the meaning<br>of section 2:239 of the Civil Code with the Company with respect to the Indenture or the transactions contemplated thereby;
(m) that none of the members of the managing board of the Company is subject to a civil law director disqualification<br>(civielrechtelijk bestuursverbod) or has been suspended (geschorst) by the court to act as a managing director of the Company<br>within the meaning of sections 106a through 106c of the Bankruptcy Act, or is subject to any other disqualification, ban or suspension<br>which compromises its authority to exercise its duties as a managing director; and
--- ---
(n) that no foreign law which may apply to the Documents, when executed or performed, or the transactions<br>contemplated thereby, affect or will affect, this opinion.
--- ---
(5) We have not investigated the laws of any jurisdiction other than the Netherlands. This opinion is limited<br>to matters of the laws of the Netherlands as they presently stand. We do not express any opinion with respect to (i) any public international<br>law or the rules of or promulgated under any treaty or by any treaty organisation, other than any provisions of EU law having direct<br>effect, (ii) matters of competition law, (iii) matters of foreign direct<br>investment law, (iv) data protection law and (v) matters of taxation.
--- ---
(6) Based upon and subject to the foregoing and to the further qualifications, limitations and exceptions<br>set forth herein, and subject to any factual matters not disclosed to us and inconsistent with the information revealed by the documents<br>reviewed by us in the course of our examination referred to above, we are as at the date hereof of the following opinion:
--- ---
(a) the Company has been duly incorporated and is validly existing under the laws of the Netherlands as a<br>private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) and has the necessary corporate capacity<br>and power to enter into the Indenture and to exercise its rights and perform its obligations thereunder;
--- ---
(b) all corporate action required to be taken by the Company to authorise the execution of the Indenture by<br>it or on its behalf and the performance of its obligations thereunder has been duly taken; and
--- ---
(c) under the express reservation that we are not qualified to assess the correct meaning of its terms as<br>it is not governed by the laws of the Netherlands, there is nothing in the laws of the Netherlands which would prevent the Indenture,<br>including the irrevocable appointment by the Company of an agent in New York to accept service of process on its behalf in respect of<br>the jurisdiction of the U.S. Federal or New York State courts in the Borough of Manhattan in the City, County and State of New York, United<br>States of America, from constituting legal, valid and binding obligations of the Company, enforceable against the Company in accordance<br>with its terms.
--- ---
(7) This opinion is subject to the following qualifications:
--- ---
(a) we express no opinion as to the accuracy of any representations given by the Company or any other party<br>(express or implied) under or by virtue of the Indenture;
--- ---
4

(b) the opinions expressed above are limited and may be affected by any applicable bankruptcy (faillissement),<br>suspension of payments (surseance van betaling), insolvency, out of court restructuring plan (onderhands akkoord) procedure,<br>moratorium, reorganisation, liquidation, fraudulent conveyance, or similar rules and laws affecting the enforceability of rights<br>of creditors generally (including rights of set-off) in any relevant jurisdiction including but not limited to section 3:45 of the Civil<br>Code and section 42 of the Bankruptcy Act concerning fraudulent conveyance, as well as by any sanctions or measures under the Sanctions<br>Act 1977 (Sanctiewet 1977) or by EU or other international sanctions and Regulation (EC) No 2271/96;
(c) the terms "legal", "valid", "binding" or "enforceable"<br>(or any combination thereof), where used in this opinion, mean that the relevant obligations are of a type which the courts of the Netherlands<br>generally recognise and enforce; the use of these terms does not suggest that the obligations will necessarily be enforced in accordance<br>with their terms in all circumstances; in particular, enforcement of such obligations in the courts of the Netherlands may be subject<br>to applicable statutes of limitation, interpretation by the court (taking into account the intention of the parties to a contract), the<br>effect of general principles of law including (without limitation) the concepts of reasonableness and fairness (redelijkheid en billijkheid)<br>and abuse of circumstances (misbruik van omstandigheden), and defences based on error (dwaling), fraud (bedrog),<br>duress (dwang), force majeure (overmacht) and set-off (verrekening);
--- ---
(d) no opinion is given as to whether any legal act (rechtshandeling) performed by the Company in entering<br>into the Indenture or exercising its rights or performing its obligations thereunder is not contrary to the corporate interest of the<br>Company for purposes of section 2:7 of the Civil Code. The validity and enforceability of the obligations of a Dutch company under a transaction<br>which it entered into may be contested by such company (or its receiver in bankruptcy (curator)) on the basis of section 2:7 of<br>the Civil Code, if both (a) the entry into the transaction was not within the scope of the objects of the company (doeloverschrijding)<br>and (b) the counterparty of the company knew or ought to have known (without any enquiry) that this was the case. The Dutch Supreme<br>Court has ruled that in determining whether a legal act (rechtshandeling) performed by a legal entity falls outside the objects<br>of that legal entity not only the description of such objects in its articles of association is relevant, but all relevant circumstances<br>must be taken into account, in particular whether the interests of the legal entity were served by the transaction;
--- ---
(e) any provision that the holder of a Note may be treated as its absolute owner may not be enforceable under<br>all circumstances;
--- ---
(f) when applying the law of a jurisdiction expressed in an agreement to be the governing law of that agreement,<br>the courts of the Netherlands (assuming they have jurisdiction over the matter):
--- ---
· will apply overriding mandatory provisions of<br>the laws of the Netherlands irrespective of the law otherwise applicable to the relevant agreement;
--- ---
· may give effect to the overriding mandatory provisions<br>of the law of the jurisdiction where the obligations arising out of the agreement have to be or have been performed, in so far as those<br>overriding mandatory provisions render performance of the agreement – in accordance with the law otherwise applicable to it –<br>unlawful;
--- ---
5

· may refuse to apply the law of another jurisdiction<br>if such application is manifestly incompatible with the public policy of the Netherlands; and
· if all the elements relevant to the situation<br>at the time of the choice of law are located in another country, may apply provisions of the law of that other country and, if that country<br>is an EU member state, provisions of EU law, in so far as those provisions cannot be derogated from by agreement;
--- ---
(g) when applying the law of a jurisdiction expressed in an agreement to be the law applicable to non-contractual<br>obligations, the courts of the Netherlands (assuming they have jurisdiction over the matter):
--- ---
· will apply overriding mandatory provisions of<br>the laws of the Netherlands irrespective of the law otherwise applicable to the relevant non-contractual obligations; and
--- ---
· may apply provisions of the<br>law of another country and, if that country is an EU member state, provisions of EU law, if all the elements relevant to the situation<br>giving rise to the non-contractual obligations are located in that other country and in so far as those provisions cannot be derogated<br>from by agreement;
--- ---
(h) under the laws of the Netherlands a power of attorney will no longer be valid or enforceable as a matter<br>of law upon the grantor of the power of attorney being declared bankrupt (failliet verklaard) or being granted suspension of payments<br>(surseance van betaling verleend); insofar as certain provisions of the Indenture, including but not limited to the appointment<br>of an agent for service of process, expressly or implicitly provide for or constitute powers of attorney, the validity of the same is<br>similarly qualified;
--- ---
(i) service of process of any proceedings before the courts of, and enforcement of judgments in, the Netherlands<br>must be performed in accordance with applicable Dutch rules of civil procedure;
--- ---
(j) any provision to the effect that proceedings may be taken against the Company in different jurisdictions<br>may not be enforceable in the courts of the Netherlands in all circumstances;
--- ---
(k) under the laws of the Netherlands, the remedy of specific performance is not available in all circumstances;<br>and
--- ---
(l) the concepts of "trust" and of "delivery of documents" as known in common law jurisdictions<br>are not known as such under the laws of the Netherlands.
--- ---
(8) In this opinion, Dutch legal concepts are expressed in English terms and not in their original Dutch terms.<br>The concepts concerned may not be identical to the concepts described by the same English terms as they exist under the laws of other<br>jurisdictions. This opinion is given by Stibbe London B.V. and may only be relied upon under the express condition that (i) any issues<br>of interpretation or liability arising hereunder will be governed by the laws of the Netherlands and will be brought exclusively before<br>a court of the Netherlands, and (ii) such liability, if any, shall be limited to Stibbe London B.V. only, to the exclusion of any<br>of its directors, partners, employees, shareholders and advisors or its or their affiliates and to the aggregate of the amount paid under<br>Stibbe London B.V.'s professional insurance in the particular instance and any applicable deductible payable by Stibbe London B.V.

(9) We assume no obligation to update this opinion or to inform any person of any changes of law or other<br>matters coming to our knowledge occurring after the date hereof which may affect this opinion in any respect. This opinion is addressed<br>to you and given for your sole benefit for the purposes of the Indenture only and may not be disclosed or quoted to any person other than<br>to your legal advisers or relied upon by any person or be used for any other purpose, without our prior written consent in each instance.
(10) This opinion letter has been prepared for use in connection with the filing by the Issuer and the Guarantors<br>of a Current Report on Form 8-K on the date hereof, which Form 8-K will be incorporated by reference into the Registration Statement<br>and speaks as of the date hereof. We hereby consent to the filing of this opinion letter as an exhibit to the Current Report on Form 8-K<br>and to the reference to Stibbe London B.V. under the caption "Validity of the Notes and the Guarantees" in the Prospectus Supplement<br>constituting a part of the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons<br>whose consent is required under Section 7 of the Securities Act, or any rules or regulations promulgated thereunder.

(e) that the choice of the laws of the State of New York to govern the Indenture is valid under such laws<br>and under the laws of any other applicable jurisdiction other than the Netherlands and would be recognised and given effect to by any<br>U.S. Federal or New York State court in the Borough of Manhattan in the City, County and State of New York, United States of America and<br>the courts of any other jurisdiction other than the Netherlands;
(f) that the Indenture constitutes legal, valid and binding obligations of the parties thereto and is enforceable<br>in accordance with its terms under all applicable laws, including the laws of the State of New York by which the Indenture is expressed<br>to be governed, other than the laws of the Netherlands;
--- ---
(g) that the information set forth in the Extract is complete and accurate on the date hereof and consistent<br>with the information contained in the files kept by the Trade Register with respect to the Company;
--- ---
(h) that all matters stated in the Resolutions and the confirmations given therein are correct on the date<br>hereof, and that the Resolutions have not been annulled, revoked or rescinded and are in full force and effect as at the date hereof and<br>that there is no law of a jurisdiction other than the Netherlands applicable under the 1978 Hague Convention on the Law applicable to<br>Agency which adversely affects the existence or extent of the authority expressed to be granted in any power of attorney;
--- ---
(i) that the Company has not been declared bankrupt (failliet verklaard), granted suspension of payments<br>(surseance van betaling verleend) or dissolved (ontbonden), nor has ceased to exist due to merger (fusie) or demerger<br>(splitsing) and that no out of court restructuring plan (onderhands akkoord) procedure is being prepared or has been commenced<br>involving the Company; although not constituting conclusive evidence, this assumption is supported by the contents of the Extract and<br>by our online search of the Central Insolvency Register of the courts of the Netherlands (Centraal Insolventieregister) (as regards<br>the out of court restructuring plan (onderhands akkoord) procedure, a search can be performed with respect to a public procedure<br>only) on the date hereof, which did not reveal any information which would render this assumption to be untrue;
--- ---
(j) that none of the insolvency proceedings listed in Annex A, as amended, to Regulation (EU) 2015/848 of<br>the European Parliament and of the Council of 20 May 2015 on insolvency proceedings (recast) has been declared applicable to the<br>Company by a court in one of the member states of the EU (with the exception of Denmark); although not constituting conclusive evidence,<br>this assumption is supported by our online search of the section on EU Registrations of the Central Insolvency Register (Centraal Insolventieregister)<br>on the date hereof, which did not reveal any information which would render this assumption to be untrue;
--- ---
(k) that, to the extent any of the provisions of the Indenture constitutes an irrevocable power of attorney<br>granted by the Company within the meaning of section 3:74 of the Civil Code, such power of attorney aims at the performance of a legal<br>act (strekt tot het verrichten van een rechtshandeling) in the interest of the proxy or a third party;
--- ---

(l) that none of the members of the managing board of the Company has a conflict of interests within the meaning<br>of section 2:239 of the Civil Code with the Company with respect to the Indenture or the transactions contemplated thereby;
(m) that none of the members of the managing board of the Company is subject to a civil law director disqualification<br>(civielrechtelijk bestuursverbod) or has been suspended (geschorst) by the court to act as a managing director of the Company<br>within the meaning of sections 106a through 106c of the Bankruptcy Act, or is subject to any other disqualification, ban or suspension<br>which compromises its authority to exercise its duties as a managing director; and
--- ---
(n) that no foreign law which may apply to the Documents, when executed or performed, or the transactions<br>contemplated thereby, affect or will affect, this opinion.
--- ---
(5) We have not investigated the laws of any jurisdiction other than the Netherlands. This opinion is limited<br>to matters of the laws of the Netherlands as they presently stand. We do not express any opinion with respect to (i) any public international<br>law or the rules of or promulgated under any treaty or by any treaty organisation, other than any provisions of EU law having direct<br>effect, (ii) matters of competition law, (iii) matters of foreign direct<br>investment law, (iv) data protection law and (v) matters of taxation.
--- ---
(6) Based upon and subject to the foregoing and to the further qualifications, limitations and exceptions<br>set forth herein, and subject to any factual matters not disclosed to us and inconsistent with the information revealed by the documents<br>reviewed by us in the course of our examination referred to above, we are as at the date hereof of the following opinion:
--- ---
(a) the Company has been duly incorporated and is validly existing under the laws of the Netherlands as a<br>private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) and has the necessary corporate capacity<br>and power to enter into the Indenture and to exercise its rights and perform its obligations thereunder;
--- ---
(b) all corporate action required to be taken by the Company to authorise the execution of the Indenture by<br>it or on its behalf and the performance of its obligations thereunder has been duly taken; and
--- ---
(c) under the express reservation that we are not qualified to assess the correct meaning of its terms as<br>it is not governed by the laws of the Netherlands, there is nothing in the laws of the Netherlands which would prevent the Indenture,<br>including the irrevocable appointment by the Company of an agent in New York to accept service of process on its behalf in respect of<br>the jurisdiction of the U.S. Federal or New York State courts in the Borough of Manhattan in the City, County and State of New York, United<br>States of America, from constituting legal, valid and binding obligations of the Company, enforceable against the Company in accordance<br>with its terms.
--- ---
(7) This opinion is subject to the following qualifications:
--- ---
(a) we express no opinion as to the accuracy of any representations given by the Company or any other party<br>(express or implied) under or by virtue of the Indenture;
--- ---
(b) the opinions expressed above are limited and may be affected by any applicable bankruptcy (faillissement),<br>suspension of payments (surseance van betaling), insolvency, out of court restructuring plan (onderhands akkoord) procedure,<br>moratorium, reorganisation, liquidation, fraudulent conveyance, or similar rules and laws affecting the enforceability of rights<br>of creditors generally (including rights of set-off) in any relevant jurisdiction including but not limited to section 3:45 of the Civil<br>Code and section 42 of the Bankruptcy Act concerning fraudulent conveyance, as well as by any sanctions or measures under the Sanctions<br>Act 1977 (Sanctiewet 1977) or by EU or other international sanctions and Regulation (EC) No 2271/96;
--- ---

(c) the terms "legal", "valid", "binding" or "enforceable"<br>(or any combination thereof), where used in this opinion, mean that the relevant obligations are of a type which the courts of the Netherlands<br>generally recognise and enforce; the use of these terms does not suggest that the obligations will necessarily be enforced in accordance<br>with their terms in all circumstances; in particular, enforcement of such obligations in the courts of the Netherlands may be subject<br>to applicable statutes of limitation, interpretation by the court (taking into account the intention of the parties to a contract), the<br>effect of general principles of law including (without limitation) the concepts of reasonableness and fairness (redelijkheid en billijkheid)<br>and abuse of circumstances (misbruik van omstandigheden), and defences based on error (dwaling), fraud (bedrog),<br>duress (dwang), force majeure (overmacht) and set-off (verrekening);
(d) no opinion is given as to whether any legal act (rechtshandeling) performed by the Company in entering<br>into the Indenture or exercising its rights or performing its obligations thereunder is not contrary to the corporate interest of the<br>Company for purposes of section 2:7 of the Civil Code. The validity and enforceability of the obligations of a Dutch company under a transaction<br>which it entered into may be contested by such company (or its receiver in bankruptcy (curator)) on the basis of section 2:7 of<br>the Civil Code, if both (a) the entry into the transaction was not within the scope of the objects of the company (doeloverschrijding)<br>and (b) the counterparty of the company knew or ought to have known (without any enquiry) that this was the case. The Dutch Supreme<br>Court has ruled that in determining whether a legal act (rechtshandeling) performed by a legal entity falls outside the objects<br>of that legal entity not only the description of such objects in its articles of association is relevant, but all relevant circumstances<br>must be taken into account, in particular whether the interests of the legal entity were served by the transaction;
--- ---
(e) any provision that the holder of a Note may be treated as its absolute owner may not be enforceable under<br>all circumstances;
--- ---
(f) when applying the law of a jurisdiction expressed in an agreement to be the governing law of that agreement,<br>the courts of the Netherlands (assuming they have jurisdiction over the matter):
--- ---
· will apply overriding mandatory provisions of<br>the laws of the Netherlands irrespective of the law otherwise applicable to the relevant agreement;
--- ---
· may give effect to the overriding mandatory provisions<br>of the law of the jurisdiction where the obligations arising out of the agreement have to be or have been performed, in so far as those<br>overriding mandatory provisions render performance of the agreement – in accordance with the law otherwise applicable to it –<br>unlawful;
--- ---

· may refuse to apply the law of another jurisdiction<br>if such application is manifestly incompatible with the public policy of the Netherlands; and
· if all the elements relevant to the situation<br>at the time of the choice of law are located in another country, may apply provisions of the law of that other country and, if that country<br>is an EU member state, provisions of EU law, in so far as those provisions cannot be derogated from by agreement;
--- ---
(g) when applying the law of a jurisdiction expressed in an agreement to be the law applicable to non-contractual<br>obligations, the courts of the Netherlands (assuming they have jurisdiction over the matter):
--- ---
· will apply overriding mandatory provisions of<br>the laws of the Netherlands irrespective of the law otherwise applicable to the relevant non-contractual obligations; and
--- ---
may apply provisions of the<br>law of another country and, if that country is an EU member state, provisions of EU law, if all the elements relevant to the situation<br>giving rise to the non-contractual obligations are located in that other country and in so far as those provisions cannot be derogated<br>from by agreement;
--- ---
(h) under the laws of the Netherlands a power of attorney will no longer be valid or enforceable as a matter<br>of law upon the grantor of the power of attorney being declared bankrupt (failliet verklaard) or being granted suspension of payments<br>(surseance van betaling verleend); insofar as certain provisions of the Indenture, including but not limited to the appointment<br>of an agent for service of process, expressly or implicitly provide for or constitute powers of attorney, the validity of the same is<br>similarly qualified;
--- ---
(i) service of process of any proceedings before the courts of, and enforcement of judgments in, the Netherlands<br>must be performed in accordance with applicable Dutch rules of civil procedure;
--- ---
(j) any provision to the effect that proceedings may be taken against the Company in different jurisdictions<br>may not be enforceable in the courts of the Netherlands in all circumstances;
--- ---
(k) under the laws of the Netherlands, the remedy of specific performance is not available in all circumstances;<br>and
--- ---
(l) the concepts of "trust" and of "delivery of documents" as known in common law jurisdictions<br>are not known as such under the laws of the Netherlands.
--- ---
(8) In this opinion, Dutch legal concepts are expressed in English terms and not in their original Dutch terms.<br>The concepts concerned may not be identical to the concepts described by the same English terms as they exist under the laws of other<br>jurisdictions. This opinion is given by Stibbe London B.V. and may only be relied upon under the express condition that (i) any issues<br>of interpretation or liability arising hereunder will be governed by the laws of the Netherlands and will be brought exclusively before<br>a court of the Netherlands, and (ii) such liability, if any, shall be limited to Stibbe London B.V. only, to the exclusion of any<br>of its directors, partners, employees, shareholders and advisors or its or their affiliates and to the aggregate of the amount paid under<br>Stibbe London B.V.'s professional insurance in the particular instance and any applicable deductible payable by Stibbe London B.V.
--- ---

(9) We assume no obligation to update this opinion or to inform any person of any changes of law or other<br>matters coming to our knowledge occurring after the date hereof which may affect this opinion in any respect. This opinion is addressed<br>to you and given for your sole benefit for the purposes of the Indenture only and may not be disclosed or quoted to any person other than<br>to your legal advisers or relied upon by any person or be used for any other purpose, without our prior written consent in each instance.
(10) This opinion letter has been prepared for use in connection with the filing by the Issuer and the Guarantors<br>of a Current Report on Form 8-K on the date hereof, which Form 8-K will be incorporated by reference into the Registration Statement<br>and speaks as of the date hereof. We hereby consent to the filing of this opinion letter as an exhibit to the Current Report on Form 8-K<br>and to the reference to Stibbe London B.V. under the caption "Validity of the Notes and the Guarantees" in the Prospectus Supplement<br>constituting a part of the Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons<br>whose consent is required under Section 7 of the Securities Act, or any rules or regulations promulgated thereunder.
