On May 29, 2026, the Company completed the offering of the Notes, and the Notes were issued pursuant to the Indenture (the "Base Indenture"), dated January 12, 2015, between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee (the "Trustee"), as amended by the Fifteenth Supplemental Indenture, dated May 29, 2026 (the "Fifteenth Supplemental Indenture" and, together with the Base Indenture, the "Indenture"), between the Company and the Trustee. Each of the 2029 Notes, the 2031 Notes, the 2033 Notes and the 2036 Notes is a separate series of debt securities under the Indenture.

The 2031 Notes bear interest at a rate of 4.800% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning December 15, 2026, and will mature on June 15, 2031. The 2033 Notes bear interest at a rate of 5.150% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, beginning December 15, 2026, and will mature on June 15, 2033.

Upon the occurrence of certain change of control events with respect to the Notes as described in the Indenture, the Company will be required to offer to repurchase the Notes at a price equal to 101% of the aggregate principal amount thereof, plus any accrued and unpaid interest to, but excluding, the date of repurchase.

The Notes were offered and sold pursuant to the Company's automatic shelf registration statement on Form S-3 (Registration No. 333-293635) (the "Registration Statement") under the Securities Act of 1933, as amended, which was filed with the Securities and Exchange Commission (the "SEC") and became effective on February 23, 2026. The Company has filed with the SEC a prospectus supplement, dated May 19, 2026 together with the accompanying prospectus, dated February 23, 2026, relating to the offering and sale of the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405, on Form S-3 (File No. 333-293635), including a related Base Prospectus, for registration under the Act of the offering and sale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) As of the Applicable Time, each of (i) the Disclosure Package and (ii) each electronic road show, when taken together as a whole with the Disclosure Package, did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), the Company was or is (as the case may be) a Well-Known Seasoned Issuer. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(s) Although the discussion set forth in the Preliminary Prospectus and the Final Prospectus under the caption "Certain U.S. Federal Income Tax Considerations" does not purport to discuss all possible United States federal income tax considerations of the purchase, ownership, or disposition of the Securities, such discussion constitutes, in all material respects, a fair and accurate summary of the United States federal income tax considerations of the purchase, ownership, and disposition of the Securities, subject to the qualifications set forth in such discussion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(t) The Company is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Disclosure Package and the Final Prospectus, will not be an "investment company" as defined in the Investment Company Act of 1940, as amended.

On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, singly or in the aggregate, have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto).

Any certificate signed by any officer of the Company and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company, as to matters covered thereby, to each Underwriter.

The Company will cause the Final Prospectus and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed. Prior to the termination of the offering of the Securities, the Company will promptly advise the Representatives (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Company will prepare a final term sheet, containing a description of final terms of the Securities and the offering thereof, in the form approved by you and substantially in the form of Schedule III hereto and to file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company promptly will (i) notify the Representatives of any such event, (ii) prepare and file with the Commission, subject to the second sentence of Section 5(a) hereof, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may reasonably designate and will maintain such qualifications in effect so long as required for the distribution of the Securities; <u>provided</u>, <u>however</u>, that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Company agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a "free writing prospectus" (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433, other than a free writing prospectus containing the information contained in the final term sheet prepared and filed pursuant to Section 5(b) hereof; <u>provided</u>, <u>however,</u> that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II hereto and any electronic road show. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a "Permitted Free Writing Prospectus." The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Company will not, without the prior written consent of the Representatives, offer, sell, contract to sell, pledge, or otherwise dispose of (or 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) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any debt securities issued or guaranteed by the Company (other than the Securities or commercial paper issued in the ordinary course of business) or publicly announce an intention to effect any such transaction, until the Business Day following the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) The Company agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (v) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification, such fees and expenses of counsel not to exceed $10,000); (vi) any filings required to be made with the Financial Industry Regulatory Authority (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such filings); (vii) the transportation and other expenses incurred by or on behalf of Company representatives in connection with presentations to prospective purchasers of the Securities; (viii) the fees and expenses of the Company's accountants and the fees and expenses of counsel (including local and special counsel) for the Company; (ix) the fees and expenses of the Trustee and its professional advisors; (x) the cost of any advertising approved by the Company in connection with the issue of the Securities; (xi) any fees charged by rating agencies for the rating of the Securities and (xii) all other costs and expenses incident to the performance by the Company of its obligations hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) The Company will use the net proceeds received in connection with this offering in the manner described in the "Use of Proceeds" section of the Disclosure Package and, except as disclosed in the Disclosure Package, the Company does not intend to use any of the proceeds from the sale of the Securities hereunder to repay any outstanding debt owed to any affiliate of any Underwriter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Conditions to the Obligations of the Underwriters</u>. The obligations of the several Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Execution Time and the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Final Prospectus, and any supplement thereto, have been filed in the manner and within the time period required by Rule 424(b); the final term sheet contemplated by Section 5(b) hereof, and any other material required to be filed by the Company pursuant to Rule 433(d), shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433; and no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use shall have been issued and no proceedings for that purpose or pursuant to Rule 401(g)(2) or pursuant to Section 8A under the Act shall have been instituted or threatened.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Company shall have requested and caused Theresa E. Corona, Deputy General Counsel Corporate and Assistant Secretary of the Company, to have furnished to the Representatives her opinion, dated the Closing Date and addressed to the Representatives, in form and substance satisfactory to the Representatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) McGuireWoods LLP, counsel to the Company, shall have furnished to the Representatives its opinion and negative assurance letter, as counsel to the Company, addressed to the Representatives and dated the Closing Date, in form and substance satisfactory to the Representatives.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Representatives shall have received from Willkie Farr & Gallagher LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company shall have furnished to the Representatives a certificate of the Company, signed by the Chief Financial Officer and the Treasurer of the Company, or such other officers of the Company as the Representatives may agree, dated the Closing Date, to the effect that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) no stop order or similar order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Company's knowledge, threatened; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) since the date of the most recent financial statements included in the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto), there has been no material adverse change, or any development involving a prospective material adverse change, in or affecting the general financial condition or results of operations or business of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) At the date hereof and at the Closing Date, the Company shall have requested and caused PricewaterhouseCoopers LLP to have furnished to the Underwriters letters, dated respectively as of the date hereof and as of the Closing Date, in form and substance satisfactory to the Underwriters of the type described in PCAOB Auditing Standard No. 6101, as amended, with respect to the financial statements and certain financial information of the Company contained or incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any amendment or supplement thereto), there shall not have been any change, or any development involving a prospective change, in or affecting the general financial condition or results of operations or business of the Company and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto) the effect of which is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Company's debt securities by any "nationally recognized statistical rating organization" (as defined in Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile and confirmed in writing. The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

The documents required to be delivered by this Section 6 shall be delivered at the office of Willkie Farr & Gallagher LLP, counsel for the Underwriters, at 300 North LaSalle Drive, Chicago, Illinois 60654, on the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Reimbursement of Underwriters' Expenses</u>. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. <u>Indemnification and Contribution</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers, employees, agents, members and its affiliates and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act (each an "Indemnified Party") against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject under the Act, the Exchange Act, other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, any Issuer Free Writing Prospectus, any electronic road show or the information included in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereof, or in any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each Indemnified Party, as incurred, for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating, or defending against, any such loss, claim, damage, liability or action; <u>provided</u>, <u>however</u>, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) below. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors and officers who sign the Registration Statement, and each person, if any, who controls the Company within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act (each an "Underwriter Indemnified Party"), to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that the (i) list of Underwriters and their respective participation in the sale of the Securities under the heading "Underwriting (Conflicts of Interest)," (ii) sentences related to concessions and reallowances under the heading "Underwriting (Conflicts of Interest)" and (iii) paragraphs under the heading "Underwriting (Conflicts of Interest)" related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) shall not relieve it from any liability that it may have under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); <u>provided</u>, <u>however</u>, that such counsel shall be reasonably satisfactory to the indemnified party; <u>provided</u>, <u>further</u>, that in connection with any proceeding or related proceedings in the same jurisdiction, the indemnifying party shall not be liable for the fees and expenses of more than one separate firm (in addition to local counsel) for all such indemnified parties. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. The indemnifying party under this Section 8 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 party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8(c), the indemnifying party agrees that it 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 such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) In the event that the indemnity provided for in paragraphs (a) or (b) of this Section 8 is unavailable or insufficient to hold harmless an Indemnified Party or Underwriter Indemnified Party, as the case may be, for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively "Losses") to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; <u>provided</u>, <u>however</u>, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is not permitted by applicable law, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus, received by the Underwriters from the Company under this Agreement. Relative fault 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 provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the discount or commission applicable to the Securities purchased by such Underwriter hereunder. The Underwriters' obligations under this Section 8(d) to contribute are several in proportion to their respective purchase obligations and not joint. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, agent and affiliate of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company who shall have signed the Registration Statement shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 8(d).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Default by an Underwriter</u>. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; <u>provided</u>, <u>however</u>, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives and the Company shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. <u>Termination</u>. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Company's Common Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency not declared on the date hereof or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereto).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Representations and Indemnities to Survive</u>. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. <u>Notices</u>. All notices and other communications required or permitted to be given under this Agreement shall be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed or transmitted and confirmed by any standard form of communication to: Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, Facsimile: (646) 291-1469, Attention: General Counsel, email: TEG.NewYork@citi.com; Barclays Capital Inc., 745 Seventh Avenue, New York, NY 10019, Attention: Syndicate Registration; BofA Securities, Inc., 114 W 47th Street, NY8-114-07-01, New York, New York 10036, Attention: High Grade Transaction Management/Legal, Fax: (646) 855-5958; Wells Fargo Securities, LLC, 550 South Tryon Street, 5<sup>th</sup> Floor, Charlotte, North Carolina 28202, Attention: Transaction Management, email: tmgcapitalmarkets@wellsfargo.com; or, if sent to the Company, will be mailed, delivered, emailed or telefaxed to Ecolab Inc.

This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. <u>Absence of Fiduciary Relationship</u>. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm's-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company's engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. <u>Integration</u>. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. <u>Applicable Law</u>. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. <u>Waiver of Jury Trial</u>. The Company and the Underwriters hereby irrevocably waive, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;19. <u>Counterparts; Severability</u>. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement. The words "execution," "signed," "signature," and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement, if any, shall include images of manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, "pdf," "tif" or "jpg") and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction.

\*\*We expect that delivery of the notes will be made against payment therefor on or about May 29, 2026, which is seven business days following the date of pricing of the notes (this settlement cycle being referred to as "T+7"). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade their notes on any date prior to one business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+7, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade their notes on any date prior to two business days before delivery should consult their own advisor.

Section 1.04 <u>Payment of Principal and Interest,</u>

In the event that definitive Notes for a series shall have been issued, all payments of principal, premium, if any, and interest with respect to the Notes of such series shall be made by the Company through the Paying Agent by wire transfer of immediately available funds in U.S. Dollars to the accounts of the registered Holders thereof; provided, that the Company may elect to make such payments at the office of the Paying Agent in The City of Minneapolis; and provided further, that the Company may at its option pay interest by check to the registered address of each Holder of a definitive Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Notes shall trade in the Depositary's Same-Day Funds Settlement System until Stated Maturity (or until they are subject to acceleration pursuant to Article VII of the Existing Indenture), and secondary market trading activity in the Notes of a series may be required by the Depositary to settle in immediately available funds with respect to Notes of such series.

In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the applicable Par Call Date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the applicable 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 the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life.

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

**ARTICLE III<br>OPTIONAL REDEMPTION**

At any time prior to the applicable Par Call Date, the Company may redeem the Notes of a series, at any time in whole or from time to time in part, in each case at the Company's option, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 100% of the principal amount of the Notes of such series to be redeemed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption
Date with respect to such series (assuming, in each case, the Notes to be redeemed matured on the applicable Par Call Date) on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, *plus* 10 basis points in respect of the
2029 Notes *, plus* 10 basis points in respect of the 2031 Notes *, plus* 15 basis points in respect of the 2033 Notes and *plus* 15 basis points in respect of the 2036 Notes, *less* (b) interest accrued to the Redemption Date with respect to such series;

*plus*, in either case, accrued and unpaid interest, if any, to but excluding the Redemption Date with respect to such series.

In addition, the Company may redeem the Notes of a series, at any time in whole or from time to time in part, at the Company's option, on or after the applicable Par Call Date, in each case at a Redemption Price equal to 100% of the principal amount of the Notes of such series to be redeemed, *plus* accrued and unpaid interest, if any, to but excluding the Redemption Date with respect to such series.

Notwithstanding the foregoing, installments of interest on the Notes of a series that are due and payable on Interest Payment Dates with respect to such series falling on or prior to a Redemption Date will be payable on the applicable Interest Payment Date to the registered Holders of the Notes of such series as of the close of business on the relevant Record Date according to the Notes of such series and the Indenture.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC's procedures) at least 10 days but not more than 60 days before the Redemption Date to each registered Holder of the Notes of a series to be redeemed by the Company or by the Trustee on its behalf; provided that notice of redemption may be delivered more than 60 days prior to the Redemption Date if the notice is issued in connection with a defeasance of such Notes or a satisfaction and discharge of such Notes. The Company shall notify the Trustee of the Redemption Date and of the principal amount of the Notes of a series to be redeemed at least 45 days prior to the Redemption Date with respect to such series, unless a shorter period is satisfactory to the Trustee.

In the case of a partial redemption with respect to a series, selection of the Notes of such series for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note of a series is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note of a series in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the partial redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. DTC's current practice is to determine by lot the amount of each participant in the Notes to redeem.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption.

Except as otherwise set forth in this Article III, the terms and conditions upon which and the manner in which the Notes may be redeemed by the Company pursuant to this Article III are governed by the provisions of Article IV of the Existing Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that the Company becomes obligated to redeem the SMR Notes pursuant to the Special Mandatory Redemption, the Company shall promptly, and in any event not more than five Business Days after the occurrence of the Special Mandatory Redemption Trigger Date, deliver notice to the Trustee of the Special Mandatory Redemption and the date upon which the SMR Notes will be redeemed (the "Special Mandatory Redemption Date," which date shall be no earlier than the third Business Day and no later than 30 days following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each Holder of SMR Notes to be redeemed. The Trustee shall then promptly mail, or deliver electronically if the SMR Notes are held by any depositary (including, without limitation, DTC) in accordance with such depositary's customary procedures, such notice of Special Mandatory Redemption to each Holder of SMR Notes to be redeemed at its registered address.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the SMR Notes to be redeemed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Upon completion of the CoolIT Systems Acquisition, the provisions in this Article IV shall cease to apply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Notwithstanding the foregoing, installments of interest on any series of the SMR Notes that are due and payable on the applicable Interest Payment Dates falling on or prior to the Special Mandatory Redemption Date shall be payable on such Interest Payment Dates to Holders as of the close of business on the relevant Record Dates in accordance with the SMR Notes and the Indenture.

This Note is one of a duly authorized issue of Securities of the Company designated as its 4.600% Notes due 2029 (the "Notes") issued under an Indenture dated as of January 12, 2015 (herein called, together with the Fifteenth Supplemental Indenture referred to below, the "Indenture"), between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. This Note is one of the Securities of the series designated on the face hereof, limited to an aggregate principal amount not to exceed $1,200,000,000, which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Notes of this series, as specified in the Fifteenth Supplemental Indenture between the Company and Trustee, dated as of May 29, 2026, establishing the form and certain terms of the Notes pursuant to the Indenture (the "Fifteenth Supplemental Indenture"). References herein to "this series" mean the series of Notes designated on the face hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Company may redeem the Notes at any time in whole or from time to time in part, in each case at the Company's option, prior to May 15, 2029 (the "Par Call Date"), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 100% of the principal amount of the Notes to be redeemed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed matured 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 (as defined in the Fifteenth Supplemental Indenture) *plus* 10 basis points *less* (b) interest accrued to the Redemption Date; *plus*, in either case, accrued and unpaid interest, if any, to but excluding the Redemption Date.

In addition, the Company may redeem the Notes, at any time in whole or from time to time in part, at the Company's option, on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, *plus* accrued and unpaid interest, if any, to but excluding the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date according to this Note and the Indenture.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC's procedures) at least 10 days but not more than 60 days before the Redemption Date to the registered Holder of the Notes to be redeemed.

In the case of a partial redemption, for so long as the Notes are held by DTC (or another depositary), the partial redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. DTC's current practice is to determine by lot the amount of each participant in the Notes to redeem. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note.

Any notice to Holders of Notes of a redemption pursuant to this paragraph 3 hereof will include the appropriate calculation of the Redemption Price, but does not need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in a Company Order delivered to the Trustee no later than two Business Days prior to the Redemption Date.

In the event that the Company becomes obligated to redeem the Notes pursuant to the Special Mandatory Redemption, the Company shall promptly, and in any event not more than five Business Days after the occurrence of the Special Mandatory Redemption Trigger Date, deliver notice to the Trustee of the Special Mandatory Redemption and the date upon which the Notes will be redeemed (the "Special Mandatory Redemption Date," which date shall be no earlier than the third Business Day and no later than 30 days following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each Holder of Notes to be redeemed. The Trustee shall then promptly mail, or deliver electronically if the Notes are held by any depositary (including, without limitation, DTC) in accordance with such depositary's customary procedures, such notice of Special Mandatory Redemption to each Holder of Notes to be redeemed at its registered address.

Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Notes to be redeemed.

Upon completion of the CoolIT Systems Acquisition, the foregoing provisions regarding Special Mandatory Redemption shall cease to apply.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to the Special Mandatory Redemption Date shall be payable on such Interest Payment Dates to Holders as of the close of business on the relevant Record Dates in accordance with this Notes and the Indenture.

ECOLAB INC.

5.150% NOTES DUE 2033

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. This Note is one of a duly authorized issue of Securities of the Company designated as its 5.150% Notes due 2033 (the "Notes") issued under an Indenture dated as of January 12, 2015 (herein called, together with the Fifteenth Supplemental Indenture referred to below, the "Indenture"), between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. This Note is one of the Securities of the series designated on the face hereof, limited to an aggregate principal amount not to exceed $1,500,000,000, which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Notes of this series, as specified in the Fifteenth Supplemental Indenture between the Company and Trustee, dated as of May 29, 2026, establishing the form and certain terms of the Notes pursuant to the Indenture (the "Fifteenth Supplemental Indenture"). References herein to "this series" mean the series of Notes designated on the face hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Company may redeem the Notes at any time in whole or from time to time in part, in each case at the Company's option, prior to April 15, 2033 (the "Par Call Date"), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 100% of the principal amount of the Notes to be redeemed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed matured 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 (as defined in the Fifteenth Supplemental Indenture) *plus* 15 basis points *less* (b) interest accrued to the Redemption Date; *plus*, in either case, accrued and unpaid interest, if any, to but excluding the Redemption Date.

In addition, the Company may redeem the Notes, at any time in whole or from time to time in part, at the Company's option, on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, *plus* accrued and unpaid interest, if any, to but excluding the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date according to this Note and the Indenture.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC's procedures) at least 10 days but not more than 60 days before the Redemption Date to the registered Holder of the Notes to be redeemed.

In the case of a partial redemption, for so long as the Notes are held by DTC (or another depositary), the partial redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. DTC's current practice is to determine by lot the amount of each participant in the Notes to redeem. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note.

Any notice to Holders of Notes of a redemption pursuant to this paragraph 3 hereof will include the appropriate calculation of the Redemption Price, but does not need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in a Company Order delivered to the Trustee no later than two Business Days prior to the Redemption Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. If (i) the completion of the CoolIT Systems Acquisition does not occur on or prior to the later of (x) September 16, 2026 or (y) such later date to which the end date under the Merger Agreement as in effect on the date hereof may be extended in accordance with the terms thereof (such later date, the "Special Mandatory Redemption End Date"), (ii) prior to the Special Mandatory Redemption End Date, the Merger Agreement is terminated or (iii) the Company otherwise notifies the Trustee that it will not pursue the completion of the CoolIT Systems Acquisition (the earlier of the date of delivery of such notice described in clause (iii), the Special Mandatory Redemption End Date and the date the Merger Agreement is terminated, the "Special Mandatory Redemption Trigger Date"), the Company shall redeem the Notes then outstanding (such redemption, the "Special Mandatory Redemption"), at a special mandatory redemption price equal to 101% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the Special Mandatory Redemption Date (as defined below) (the "Special Mandatory Redemption Price").

In the event that the Company becomes obligated to redeem the Notes pursuant to the Special Mandatory Redemption, the Company shall promptly, and in any event not more than five Business Days after the occurrence of the Special Mandatory Redemption Trigger Date, deliver notice to the Trustee of the Special Mandatory Redemption and the date upon which the Notes will be redeemed (the "Special Mandatory Redemption Date," which date shall be no earlier than the third Business Day and no later than 30 days following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each Holder of Notes to be redeemed. The Trustee shall then promptly mail, or deliver electronically if the Notes are held by any depositary (including, without limitation, DTC) in accordance with such depositary's customary procedures, such notice of Special Mandatory Redemption to each Holder of Notes to be redeemed at its registered address.

Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Notes to be redeemed.

Upon completion of the CoolIT Systems Acquisition, the foregoing provisions regarding Special Mandatory Redemption shall cease to apply.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to the Special Mandatory Redemption Date shall be payable on such Interest Payment Dates to Holders as of the close of business on the relevant Record Dates in accordance with this Notes and the Indenture.

"CoolIT Systems" means Frigeo Holdings LLC.

"CoolIT Systems Acquisition" means the acquisition of CoolIT Systems in accordance with the terms of the Merger Agreement.

"Merger Agreement" means the Agreement and Plan of Merger, dated as of March 20, 2026, by and among Ecolab Inc., Ecolab U.S. 15 LLC, a wholly owned subsidiary of Ecolab Inc., Frigeo Holdings LLC and KKR Aggregator L.P. (solely in its capacity as equityholder representative).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Upon the occurrence of a Change of Control Repurchase Event, unless all of the Notes have been called for redemption pursuant to paragraph 3 of this Note, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of such Holder's Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Notes repurchased *plus* any accrued and unpaid interest on the Notes repurchased to the date of repurchase. "Change of Control Repurchase Event" means the occurrence of both a Change of Control and a Below Investment Grade Rating Event, as such terms are defined in the Indenture. The Change of Control Offer will be made in accordance with the terms specified in the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. If an Event of Default with respect to the Notes (other than certain events of bankruptcy, insolvency or reorganization) shall occur and be continuing, the Trustee or the Holders of 25% or more in principal amount of the Outstanding Notes may declare the principal of and accrued but unpaid interest on this Note to be immediately due and payable in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration and its consequences may, in certain events, be annulled by the Holders of a majority in principal amount of the Outstanding Notes. If an Event of Default with respect to the Notes relating to certain events of bankruptcy, insolvency or reorganization shall occur and be continuing, then the principal amount of and all accrued but unpaid interest on this Note shall automatically, and without any declaration or any other action on the part of the Trustee or any Holder, become due and payable as provided in the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of Notes under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. No reference herein to the Indenture and no provisions of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered on the Register of the Company, upon surrender of this Note for registration of transfer at the office or agency to be maintained by the Company for that purpose, or at such other office or agency as may be established by the Company for such purpose pursuant to the Indenture (initially the principal corporate trust office of the Trustee in Minneapolis, Minnesota), duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, and duly executed by the Holder hereof or such Holder's attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for like aggregate principal amount, will be issued to the designated transferee or transferees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. The Notes are issuable only in fully registered form, without coupons, in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000. As provided in the Indenture, and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes in authorized denominations, as requested by the Holder surrendering the same.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. Prior to the due presentment of this Note for registration of transfer or exchange, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee, nor any such agent shall be affected by notice to the contrary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. Interest on this Note shall be computed on the basis of a 360-day year of twelve 30- day months. Interest shall be payable to and excluding any Interest Payment Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 100% of the principal amount of the Notes to be redeemed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed matured 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 (as defined in the Fifteenth Supplemental Indenture) *plus* 15 basis points *less* (b) interest accrued to the Redemption Date; *plus*, in either case, accrued and unpaid interest, if any, to but excluding the Redemption Date.

In addition, the Company may redeem the Notes, at any time in whole or from time to time in part, at the Company's option, on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, *plus* accrued and unpaid interest, if any, to but excluding the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date according to this Note and the Indenture.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC's procedures) at least 10 days but not more than 60 days before the Redemption Date to the registered Holder of the Notes to be redeemed.

In the case of a partial redemption, for so long as the Notes are held by DTC (or another depositary), the partial redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. DTC's current practice is to determine by lot the amount of each participant in the Notes to redeem. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note.

Any notice to Holders of Notes of a redemption pursuant to this paragraph 3 hereof will include the appropriate calculation of the Redemption Price, but does not need to include the Redemption Price itself. The actual Redemption Price, calculated as described above, will be set forth in a Company Order delivered to the Trustee no later than two Business Days prior to the Redemption Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Upon the occurrence of a Change of Control Repurchase Event, unless all of the Notes have been called for redemption pursuant to paragraph 3 of this Note, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of such Holder's Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Notes repurchased *plus* any accrued and unpaid interest on the Notes repurchased to the date of repurchase. "Change of Control Repurchase Event" means the occurrence of both a Change of Control and a Below Investment Grade Rating Event, as such terms are defined in the Indenture. The Change of Control Offer will be made in accordance with the terms specified in the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. If an Event of Default with respect to the Notes (other than certain events of bankruptcy, insolvency or reorganization) shall occur and be continuing, the Trustee or the Holders of 25% or more in principal amount of the Outstanding Notes may declare the principal of and accrued but unpaid interest on this Note to be immediately due and payable in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration and its consequences may, in certain events, be annulled by the Holders of a majority in principal amount of the Outstanding Notes. If an Event of Default with respect to the Notes relating to certain events of bankruptcy, insolvency or reorganization shall occur and be continuing, then the principal amount of and all accrued but unpaid interest on this Note shall automatically, and without any declaration or any other action on the part of the Trustee or any Holder, become due and payable as provided in the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of Notes under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. No reference herein to the Indenture and no provisions of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered on the Register of the Company, upon surrender of this Note for registration of transfer at the office or agency to be maintained by the Company for that purpose, or at such other office or agency as may be established by the Company for such purpose pursuant to the Indenture (initially the principal corporate trust office of the Trustee in Minneapolis, Minnesota), duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, and duly executed by the Holder hereof or such Holder's attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for like aggregate principal amount, will be issued to the designated transferee or transferees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. The Notes are issuable only in fully registered form, without coupons, in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000. As provided in the Indenture, and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes in authorized denominations, as requested by the Holder surrendering the same.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. Prior to the due presentment of this Note for registration of transfer or exchange, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee, nor any such agent shall be affected by notice to the contrary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. Interest on this Note shall be computed on the basis of a 360-day year of twelve 30- day months. Interest shall be payable to and excluding any Interest Payment Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. This Note shall not be valid until authenticated by the manual signature of the Trustee or an Authenticating Agent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. Customary abbreviations may be used in the name of a Holder 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), CUT (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. Each Holder of this Note covenants and agrees by such Holder's acceptance thereof to comply with and be bound by the foregoing provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;17. All terms used in this Note which are defined in the Indenture and not otherwise defined in this Note shall have the meanings assigned to them in the Indenture.

**<u>Our Opinions</u>**

Based on and subject to the foregoing and the exclusions, qualifications, limitations and other assumptions set forth in this opinion letter, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Organizational Status</u>. The Company is a validly existing corporation under the laws of the State of Delaware and is in good standing under such laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Power and Authority</u>. The Company has the corporate power and authority to issue the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Validity of the Notes</u>. The Notes constitute the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, under the laws of State of New York.

**<u>Matters Excluded from Our Opinions</u>**

We express no opinion with respect to the following matters:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Indemnification and Change of Control</u>. The enforceability of any agreement relating to (i) indemnification, contribution or exculpation from costs, expenses or other liabilities or (ii) changes in the organizational control or ownership of any party, which agreement (in the case of clause (i) or clause (ii)) is contrary to public policy or Applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Jurisdiction, Venue, etc</u>. The enforceability of any agreement to submit to the jurisdiction of any specific federal or state court (other than the enforceability in a court of the State of New York of any such agreement to submit to the jurisdiction of a court of the State of New York), to waive any objection to the laying of the venue, to waive the defense of *forum non conveniens* in any action or proceeding referred to therein, to waive trial by jury, to effect service of process in any particular manner or to establish evidentiary standards, and any agreement regarding the choice of law governing any Subject Document (other than the enforceability in a court of the State of New York or in a federal court sitting in the State of New York and applying New York law to any such agreement that the laws of the State of New York shall govern).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Remedies</u>. The enforceability of any provision in any Subject Document to the effect that rights or remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to any other right or remedy, that the election of some particular remedy does not preclude recourse to one or more others or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy.

**<u>Qualifications and Limitations Applicable to Our Opinions</u>**

The opinions set forth above are subject to the following qualifications and limitations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Applicable Law</u>. Our opinions are limited to the Applicable Law, and we do not express any opinion concerning any other law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Bankruptcy</u>. Our opinions are subject to the effect of any applicable bankruptcy, insolvency (including laws relating to preferences, fraudulent transfers and equitable subordination), reorganization, moratorium and other similar laws affecting creditors' rights generally.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Equitable Principles</u>. Our opinions are subject to the effect of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including concepts of materiality, reasonableness, good faith and fair dealing. In applying such principles, a court, among other things, might limit the availability of specific equitable remedies (such as injunctive relief and the remedy of specific performance), might not allow a creditor to accelerate maturity of debt or exercise other remedies upon the occurrence of a default deemed immaterial or for non-credit reasons or might decline to order a debtor to perform covenants in a Subject Document.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Unenforceability of Certain Provisions</u>. Provisions contained in the Notes or the Subject Documents that require waivers or amendments to be made only in writing may be unenforceable or ineffective, in whole or in part. The inclusion of such provisions, however, does not render any of the Notes or the Subject Documents invalid as a whole.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) <u>Choice of New York Law and Forum</u>. To the extent that any of our opinions relate to the enforceability of the choice of New York law or any choice of New York forum provisions of any Subject Document, our opinion is rendered in reliance upon N.Y. Gen. Oblig. Law §§ 5-1401 and 5-1402 and N.Y. CPLR 327(b) and is subject to the qualification that such enforceability may be limited by principles of public policy, comity and constitutionality. We express no opinion as to whether a United States federal court would have subject-matter or personal jurisdiction over a controversy arising under the Subject Documents.

**<u>Miscellaneous</u>**

The foregoing opinions are being furnished only for the purpose referred to in the first paragraph of this opinion letter. Our opinions are based on statutes, regulations and administrative and judicial interpretations that are subject to change. We undertake no responsibility to update or supplement these opinions subsequent to the date hereof. Headings in this opinion letter are intended for convenience of reference only and shall not affect its interpretation. We hereby consent to the filing of this opinion letter as an exhibit to the Company's Current Report on Form 8-K filed on the date hereof, to the incorporation by reference of this opinion of counsel into the Registration Statement, and to the reference to our firm in the Prospectus under the caption "Legal Matters."
