The Notes will be issued under an indenture dated as of February 6, 2024 (the "<u>Indenture</u>," which term, for purposes of this Agreement and each series of Notes herein, includes the applicable Officer's Certificate with respect to such series of Notes delivered pursuant to Section 301 of the Indenture) between the Company and U.S. Bank Trust Company, National Association, as Trustee. As used herein, unless the context otherwise requires, the term "<u>Underwriters</u>" shall mean the firms named as Underwriters in Schedule I, and the terms "<u>you</u>" or "<u>Representatives</u>" shall mean BofA Securities, Inc., Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC. Terms not otherwise defined herein shall have the meanings specified in the Indenture. For purposes hereof, the term "<u>Operative Agreements</u>" shall mean, collectively, this Agreement, the Indenture and the Notes.

------

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

The Company has filed with the Securities and Exchange Commission (the "<u>Commission</u>") a registration statement on Form S-3 (No. 333-276909), including the related preliminary prospectus or prospectuses, which registration statement automatically became effective upon filing on February 7, 2024, and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the "<u>1939 Act</u>"). Such registration statement covers the registration of debt securities of the Company, including the Notes, under the Securities Act of 1933, as amended (the "<u>1933 Act</u>"). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of paragraph (b) of Rule 424 ("<u>Rule 424(b)</u>") of the rules and regulations of the Commission (the "<u>1933 Act Regulations</u>") under the 1933 Act. Such registration statement as amended to the date of this Agreement, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430B under the 1933 Act and the documents incorporated therein pursuant to Part I, Item 12 of Form S-3 as of its most recent effective date, is hereinafter referred to as the "<u>Registration Statement</u>," and the related base prospectus in the form first used to confirm sales of the Notes (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the 1933 Act), including the documents incorporated therein pursuant to Part I, Item 12 of Form S-3 as of such date, is hereinafter referred to as the "<u>Base Prospectus</u>." The Base Prospectus, as supplemented by the prospectus supplement specifically relating to the Notes in the form first used to confirm sales of the Notes (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the 1933 Act), including the documents incorporated therein pursuant to Part I, Item 12 of Form S-3 as of such date of such prospectus or prospectus supplement, is hereinafter referred to as the "<u>Prospectus</u>," and the term "preliminary prospectus" means any preliminary form of the Prospectus.

For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("<u>EDGAR</u>").

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the "<u>1934 Act</u>"), which is incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, such preliminary prospectus or the Prospectus, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Representations and Warranties</u>. (a) The Company represents and warrants to each Underwriter as of the date hereof and agrees with each Underwriter 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;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Company has been duly organized and is validly existing as a corporation, in good standing under the laws of the jurisdiction of its organization and has the corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package (as defined below) and the Prospectus; the Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where those failures to so qualify, individually or in the aggregate, would not have a material adverse effect on the business, properties, financial condition, results of operations or prospects of the Company and its consolidated subsidiaries taken as a whole or the ability of the Company to perform its obligations under, and consummate the transactions contemplated by, the Operative Agreements (a "<u>Material Adverse Effect</u>"); and none of the subsidiaries of the Company is a "significant subsidiary" (as defined in Rule 1-02 of Regulation S-X).

&nbsp;&nbsp;&nbsp;&nbsp;&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) The Company is a well-known seasoned issuer (as defined in Rule 405 of the 1933 Act Regulations) eligible to use the Registration Statement as an automatic shelf registration statement and the Company has not received notice that the Commission objects to the use of the Registration Statement as an automatic shelf registration statement. At the time of first filing of the Registration Statement, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Notes and at the date hereof, the Company was not and is not an "ineligible issuer," as defined in Rule 405 of the 1933 Act Regulations in connection with the offering pursuant to Rules 164, 405 and 433 of the 1933 Act Regulations. The Registration Statement has become effective; and no stop order suspending the effectiveness of the Registration Statement has been issued, and, to the Company's knowledge, no proceedings for that purpose have been initiated or threatened by the Commission and any request on the part of the Commission for additional information has been complied with.

At the respective times the first filing of the Registration Statement and each amendment thereto became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the 1933 Act Regulations and at the Closing Time (as defined below), the Registration Statement complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations, and the 1939 Act and the rules and regulations of the Commission thereunder and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

Each preliminary prospectus (including the prospectus or prospectuses filed as part of the first filing of the Registration Statement or any amendment thereto) complied when so filed in all material respects with the 1933 Act Regulations (after taking into account the information permitted to be omitted pursuant to Rules 430B and 430C of the 1933 Act Regulations, as applicable) and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

As of the Applicable Time (as defined below), none of (x) the Issuer General Use Free Writing Prospectus(es) (as defined below) issued as of or prior to the Applicable Time, the Statutory Prospectus (as defined below) and the Final Term Sheet (as defined below), all considered together (collectively, the "<u>General Disclosure Package</u>") or (y) when considered with the General Disclosure Package, (i) any individual Issuer Limited Use Free Writing Prospectus or (ii) any "bona fide electronic road show" as defined in Rule 433(h)(5) under the 1933 Act Regulations or additional written communication listed on Schedule IV (collectively, "<u>Company Additional Written Communication</u>"), included any untrue statement of a material fact or omitted 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. Any Issuer Free Writing Prospectus that the Company is required to file pursuant to Rule 433(d) of the 1933 Act Regulations has been, or will be, filed with the Commission in accordance with the requirements of the 1933 Act and the 1933 Act Regulations. Each Issuer Free Writing Prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) of the 1933 Act Regulations or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations. Except for the Issuer General Use Free Writing Prospectuses, if any, identified in Schedule III hereto, and Company Additional Written Communications, if any, identified in Schedule IV, the Company has not prepared, used or referred to, and will not, without your prior consent, prepare, use or refer to, any Issuer Free Writing Prospectus.

As used in this subsection and elsewhere in this Agreement:

"<u>Applicable Time</u>" means 3:30 p.m. (Eastern time) on October 27, 2025 or such other time as agreed by the Company and the Representatives.

"<u>Final Term Sheet</u>" means the pricing term sheet attached hereto as Schedule II.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Notes or until any earlier date that the issuer notified or notifies the Representatives as described in Section 5(e), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any preliminary prospectus relating to the Notes, the Statutory Prospectus, the General Disclosure Package or the Prospectus, including any document incorporated by reference therein and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified.

The representations and warranties in this Section 1(a)(ii) shall not apply to (a) Underwriter Information (as defined below) or (b) that part of the Registration Statement which constitutes the Trustee's Statement of Eligibility and Qualification under the 1939 Act (Form T-1).

&nbsp;&nbsp;&nbsp;&nbsp;&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) The documents incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations promulgated thereunder (the "<u>1934 Act Regulations</u>"), and, when read together and with the other information in the Prospectus and the General Disclosure Package, at the time the Registration Statement and any amendments thereto became effective, at the time the Prospectus was first filed with the Commission in accordance with Rule 424(b), at the Applicable Time and at the Closing Time, did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were or are 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;&nbsp;&nbsp;&nbsp;&nbsp;(iv) The consolidated financial statements of the Company included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus present fairly in all material respects the consolidated financial position of the Company and its subsidiaries as of the dates indicated and the results of operations, changes in stockholders' equity and cash flows of the Company and its subsidiaries, for the respective periods covered thereby, all in conformity with generally accepted accounting principles applied, except as stated therein, on a consistent basis throughout the entire period involved; and the financial schedules included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus meet the requirements of the 1933 Act Regulations or the 1934 Act Regulations, as applicable, and fairly present the information required to be shown therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Offering by Underwriters</u>. It is understood that the several Underwriters propose to offer the Notes for sale to the public as set forth in the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Immediately following the execution of this Agreement and subject to paragraph (c) below, the Company will cause the Prospectus containing the information omitted in reliance upon Rule 430B, 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 (without reliance on Rule 424(b)(8)), and will furnish to the Underwriters named therein as many copies of the Prospectus as you shall reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Company will notify you immediately (i) of the effectiveness of any amendment to the Registration Statement, (ii) of the transmittal to the Commission for filing of any supplement to the Prospectus or any document to be filed pursuant to the 1934 Act that will be incorporated by reference in the Prospectus, (iii) of the receipt of any comments from the Commission with respect to the Registration Statement or the Prospectus, (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or any document incorporated by reference therein or otherwise deemed to be a part thereof or for additional information, (v) of any order preventing or suspending the use of any preliminary prospectus, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement, (vi) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Notes, and (vii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Notes for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof as soon as possible. The Company will file the Final Term Sheet pursuant to Rule 433(d) under the 1933 Act within the time required by such Rule and will file promptly all other material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the 1933 Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) For so long as a Prospectus is required to be delivered in connection with the Notes (including in circumstances where such requirement may be satisfied pursuant to Rule 172), the Company will give you notice of its intention to file or prepare any amendment to the Registration Statement or any amendment or supplement to the Prospectus, whether by the filing of documents pursuant to the 1934 Act, the 1933 Act, or otherwise, and will furnish you with copies of any such amendment or supplement or other documents proposed to be filed or prepared a reasonable time in advance of such proposed filing or preparation, as the case may be.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Company will deliver to you as many signed and conformed copies of the Registration Statement (as originally filed) and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated by reference in the Prospectus) as you may reasonably request. The Company will furnish to you as many copies of the Prospectus (as amended or supplemented) as you shall reasonably request, so long as you are required to deliver a Prospectus in connection with sales or solicitations of offers to purchase the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any event occurs as a result of which the General 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 light of the circumstances under which they were made at such time not misleading, the Company will (i) notify promptly the Representatives so that any use of the General Disclosure Package may cease until it is amended or supplemented; (ii) subject to paragraph (c) above, amend or supplement the General 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;(f) If at any time when the Prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes (including in circumstances where such requirement may be satisfied pursuant to Rule 172) any event shall occur or condition exist as a result of which it is necessary to further amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary at any such time to amend or supplement the Registration Statement or the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and, subject to paragraph (c) above, file with the Commission such amendment or supplement, whether by filing documents pursuant to the 1934 Act, the 1933 Act, or otherwise, as may be necessary to correct such untrue statement or omission or to make the Registration Statement and Prospectus comply with such requirements. If at any time when the Prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes (including in circumstances where such requirement may be satisfied pursuant to Rule 172) there occurred or occurs an event or development as a result of which an Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement relating to the Notes or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify you and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) With respect to the sale of the Notes, the Company will make generally available to its security holders earning statements (in form complying with the provisions of Rule 158 under the 1933 Act), which will satisfy the requirements of Section 11(a) of the 1933 Act.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Company will endeavor, in cooperation with you, to qualify the Notes for offering and sale under the applicable securities laws of such states and other jurisdictions as the Underwriters may designate, and will maintain such qualifications in effect for so long as may be required for the distribution of the Notes; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or to subject itself to taxation as doing business in any jurisdiction in which it is not otherwise required to be so qualified or subject itself to ongoing securities or corporate law reporting requirements in the jurisdiction. The Company will file such statements and reports as may be required by the laws of each jurisdiction in which the Notes have been qualified as provided above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Between the date of this Agreement and the Closing Date, the Company shall not, without your prior written consent, offer, sell, or enter into any agreement to sell (as public debt securities registered under the 1933 Act (other than the Notes) or as debt securities which may be resold in a transaction exempt from the registration requirements of the 1933 Act in reliance on Rule 144A thereunder and which are marketed through the use of a disclosure document containing substantially the same information as a prospectus for similar debt securities registered under the 1933 Act), any debt securities similar to the Notes, equipment notes, pass through certificates, equipment trust certificates or equipment purchase certificates secured by aircraft owned or leased by the Company (or rights relating thereto).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior written consent of the Company and the Representatives, it has not made and will not make any offer relating to the Notes 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 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; provided, however, that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Issuer General Use Free Writing Prospectus. The Company represents that it has treated or agrees that it will treat each Issuer General Use Free Writing Prospectus as an Issuer Free Writing Prospectus, and has complied and will comply with the requirements of Rule 433 applicable to any Issuer General Use Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Subsequent to the execution and delivery of this Agreement, there shall not have occurred any Material Adverse Change that, in your judgment, is material and adverse and that makes it, in your judgment, impracticable or inadvisable to proceed with the completion of the public offering of the Notes on the terms and in the manner contemplated by the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) You shall have received a certificate of the President, Chief Executive Officer, & Vice Chairman of the Board or the Executive Vice President and Chief Financial Officer of the Company, on the one hand, and the Treasurer, the Assistant Treasurer, the Secretary or an Assistant Secretary of the Company, on the other hand, dated as of 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;&nbsp;&nbsp;&nbsp;&nbsp;(i) the representations and warranties of the Company in this Agreement are true and correct in all material respects at and as of the Closing Time with the same effect as if made at the Closing Time 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 Time;

&nbsp;&nbsp;&nbsp;&nbsp;&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 suspending the effectiveness of the Registration Statement 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;&nbsp;&nbsp;&nbsp;&nbsp;(iii) since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus, there has been no Material Adverse Change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) At the time of execution of this Agreement, the Underwriters shall have received a letter dated such date, in form and substance satisfactory to the Underwriters, from the Company's independent public accountants, containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain other financial or statistical data and certain financial information contained in or incorporated by reference into the Registration Statement, the General Disclosure Package and the Prospectus.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) At the Closing Time, the Underwriters shall have received a letter, dated as of Closing Date, from the Company's independent public accountants to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (e) of this Section, except that the specified date referred to shall be a date not more than three business days prior to Closing Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) At the Closing Time, counsel for the Underwriters shall have been furnished with such documents and opinions as such counsel may reasonably require for the purpose of enabling such counsel to pass upon the issuance and sale of Notes as herein contemplated and related proceedings, or in order to evidence the accuracy and completeness of any of the representations and warranties, or the fulfillment of any of the conditions, herein contained.

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 in all material respects reasonably satisfactory in form and substance to you and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be cancelled by you at any time at or prior to the Closing Date, and such termination shall be without liability of any party to any other party except as provided in Section 7 hereof. Notice of any such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. Notwithstanding any such termination, the provisions of Sections 8 and 11 shall remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Payment of Expenses</u>. The Company will pay all expenses incident to the performance of its obligations under this Agreement, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the filing of the Registration Statement and all amendments thereto, any preliminary prospectus, any Issuer Free Writing Prospectus, and the Prospectus and any amendments or supplements thereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the qualification of the Notes under securities laws in accordance with the provisions of Section 5(h), including filing fees and the reasonably incurred fees and disbursements of counsel to the Underwriters in connection therewith and in connection with the preparation of any Blue Sky Survey;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) any fees charged by rating agencies for the rating of the Notes;

If this Agreement is terminated by you in accordance with the provisions of Section 6 hereof, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonably incurred fees and disbursements of Sidley Austin LLP, counsel for the Underwriters. However, in any other case, including any termination pursuant to Section 9 or 10 hereof or no termination at all, the Underwriters will pay all of their own expenses, including their fees of counsel, transfer or other stamp taxes on resale of any of the Notes and any advertising expenses connected with any offers they may make.

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

&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 affiliates (as such term is defined in Rule 405 under the 1933 Act), its selling agent and each person, if any, who controls such Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any Underwriter or any such controlling person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereof) or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the

------

statements therein not misleading, or caused by any untrue statement or alleged untrue statement of a material fact included in the Base Prospectus, the Statutory Prospectus, any preliminary prospectus relating to the Notes, any Issuer Free Writing Prospectus, any "issuer information" filed or required to be filed pursuant to Rule 433(d) under the 1933 Act Regulations, any "road show" as defined in Rule 433(h) under the 1933 Act Regulations or the Prospectus (or in any amendment or supplement thereto), any Company Additional Written Communication or any Testing-the-Waters Communication, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except in each case insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by the Representatives expressly for inclusion in any such document ("<u>Underwriter Information</u>"). The Company hereby acknowledges that for purposes of this Agreement, the only Underwriter Information furnished shall be the information in the third paragraph under the heading "Underwriting," the information in the third sentence under the heading "Underwriting—New Issue of Notes" and the information in the third sentence of the first paragraph and the first sentence of the second paragraph under the heading "Underwriting—Price Stabilization and Short Positions," in each case contained in the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of the officers who signed the Registration Statement and each person, if any, who controls the Company, within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, to the same extent as the foregoing indemnity from the Company to such Underwriter but only with reference to the Underwriter Information provided by such Underwriter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) above, such person (the "<u>indemnified party</u>") shall promptly notify the person against whom such indemnity may be sought (the "<u>indemnifying party</u>") in writing. The indemnifying party, upon request of the indemnified party, shall, and the indemnifying party may elect to, retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and the indemnifying party shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, or (iii) the indemnifying party shall have failed to retain counsel as required by the prior sentence to represent the indemnified party within a reasonable amount of time. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. The firm chosen to represent the indemnified parties

------

shall be designated in writing by you in the case of parties indemnified pursuant to paragraph (a) above and by the Company in the case of parties indemnified pursuant to paragraph (b) above. The indemnifying party 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 from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested in writing an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, 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 60 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 of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) To the extent the indemnification provided for in paragraph (a) or (b) of this Section 8 is required to be made but is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities, then the applicable indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of such Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of such Notes shall be deemed to be in the same respective proportions as the proceeds from the offering of such Notes received by the Company (before deducting expenses) less total underwriting discounts and commissions paid to the Underwriters by the Company, and the total underwriting discounts and commissions paid to the Underwriters by the Company, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of such Notes. The relative fault of the Company on the one hand and of the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or information supplied by the Underwriters, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amount of Notes they have purchased hereunder, and not joint.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by <u>pro rata</u> allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. <u>Default by an Underwriter</u>. If, on the Closing Date, any Underwriter or Underwriters default in their obligations to purchase Notes hereunder and the aggregate principal amount of the Notes that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Notes, you may make arrangements satisfactory to the Company for the purchase of such Notes by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Notes that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Notes with respect to which such default or defaults occurs exceeds 10% of the total principal amount of the Notes and arrangements satisfactory to you and the Company for purchase of such Notes by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 7 and 8 hereof. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

&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 Underwriters, immediately upon notice to the Company, at any time if after the execution and delivery of this Agreement and prior to the Closing Time (a) trading generally shall have been suspended or materially limited on or by, as the case may be, either the New York Stock Exchange or the Nasdaq Global Market, (b) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (c) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, (d) any outbreak or escalation of hostilities shall have occurred in which the United States is involved, any declaration of war by Congress or any substantial national or international calamity or emergency shall occur and the effect of which is such as to make it, in your judgment, impracticable or inadvisable to proceed with the offering, sale or delivery of the Notes on the terms and in the manner contemplated in the Prospectus, or (e) there shall have

------

occurred such a material adverse change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the United States shall be such) as to make it, in your judgment, impracticable or inadvisable to proceed with the offering, sale or delivery of the Notes on the terms and in the manner contemplated in the Prospectus. In the event of any such termination of this Agreement, the provisions of Section 7 hereof, the indemnity and contribution agreements set forth in Section 8 hereof, and the provisions of Sections 11 through 15 hereof shall remain in effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. <u>Representations and Indemnities to Survive</u>. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any termination of this Agreement, any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Notes. If for any reason the purchase of the Notes by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 7 and the respective obligations of the Company and the Underwriters pursuant to Section 8 shall remain in effect. If the purchase of the Notes by the Underwriters is not consummated for any reason other than solely because of the occurrence of the termination of this Agreement pursuant to Section 9 or 10, the Company will reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by them in connection with the offering of such Notes and comply with its other obligations under Section 7.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. <u>Notices</u>. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed, delivered by Federal Express service or transmitted by any standard form of telecommunication.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. <u>Successors</u>. This Agreement shall inure to the benefit of and be binding upon you and the Company and any Underwriter who becomes a party hereto and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any firm or corporation, other than the parties hereto and their respective successors and the controlling persons and officers and directors referred to in Section 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision

------

herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto, their respective successors and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. <u>Arm's-Length Transactions</u>. The Company acknowledges and agrees that (a) the purchase and sale of the Notes pursuant to this Agreement, including the determination of the public offering price of the Notes and any related discounts and commissions, is an arm's-length commercial transaction between the Company, on the one hand, and the several Underwriters on the other, (b) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate, and (f) any review by a Representative or any Underwriter of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of such Representative or such Underwriter and shall not be on behalf of the Company or any other person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. <u>APPLICABLE LAW</u>. THIS AGREEMENT, AND ANY CLAIM, CONTROVERSY OR DISPUTE RELATING OR ARISING OUT OF THIS AGREEMENT, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. <u>Waiver of Jury Trial</u>. All parties 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;17. <u>Counterparts</u>. This Agreement may be executed in one or more counterparts and when a counterpart has been executed by each party, all such counterparts taken together shall constitute one and the same agreement. A party may submit its signed counterpart of this Agreement by facsimile and such counterpart so received by facsimile shall for all purposes constitute an original.

------

The words "execution," "signed," "signature," and words of like import in this Agreement or in any instruments, agreements, certificates, legal opinions, negative assurance letters or other documents entered into or delivered pursuant to or in connection with this Agreement or the Indenture 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, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;18. <u>Patriot Act</u>. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

TRUSTEE'S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated herein referred to in the within-mentioned Indenture.

**U.S. BANK TRUST COMPANY, NATIONAL ASSOCIATION** 

---

| | |
|:---|:---|
|  as Trustee | as Trustee |

------

This Security is one of a duly authorized issue of debt securities of the Company, issued and to be issued in one or more series under an Indenture, dated as of February 6, 2024 (herein called the "<u>Indenture</u>"), between the Company and U.S. Bank Trust Company, National Association, as Trustee (herein called the "<u>Trustee</u>", which term includes any successor Trustee under the Indenture), to which Indenture, all indentures supplemental thereto, and the Officer's Certificate dated November 3, 2025, setting forth the terms of the debt securities of this series, reference is hereby made for a statement of the respective rights, limitation of rights, duties, and immunities thereunder of the Company, the Trustee, and the Holders of the Securities (as defined below) and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of a series designated as 4.375% Notes due 2028 (the "<u>Securities</u>"). This Security is a Global Security representing a portion of the Securities, initially limited in aggregate principal amount to $750,000,000, but subject to the right of the Company to issue and sell additional Securities in the future without the consent of the Holders thereof. Any additional securities of this series, together with this Security, shall constitute a single series under the Indenture.

**<u>Optional Redemption</u>**

Prior to October 15, 2028 (the "Par Call Date"), the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities 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 plus 15 basis points less (b) interest accrued to the Redemption Date, and (2) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date. In either case, the redemption is subject to the right of the Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or before the Redemption Date.

"Treasury Rate" means, with respect to any Redemption Date for the Securities, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily) - H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). 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 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 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. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the 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.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, the Trustee will have no duty to calculate the Redemption Price, nor will it have any duty to review or verify our calculations of the Redemption Price.

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

In the case of a partial redemption of the Securities, selection of the Securities 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 Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates to the Security will state the portion of the principal amount of the Security to be redeemed. A new Security in a principal amount equal to the unredeemed portion of the Security will be issued in the name of the Holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities are held by DTC (or another Depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the Depositary.

------

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

Subject to the provisions of Section 1102 of the Indenture, any such redemption may, at the Company's discretion, be conditioned upon (i) the occurrence of a Change of Control (as defined below) or (ii) the closing of another transaction, including a sale of securities or other financing, in each case as specified in the notice in reasonable detail.

**<u>Change of Control</u>**

Upon the occurrence of a Change of Control Triggering Event, unless the Company has otherwise exercised its right to redeem the Securities, each Holder of such Securities will have the right to require the Company to purchase all or a portion of such Holder's Securities pursuant to the offer described below (the "Change of Control Offer"), at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of purchase, subject to the rights of Holders of Securities on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date.

Within 30 days following the date upon which the Change of Control Triggering Event occurs, or at the Company's option, prior to any Change of Control but after the public announcement of the Change of Control, unless the Company has otherwise exercised its right to redeem the Securities, the Company will be required to deliver a notice to each Holder of Securities, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent, other than as may be required by law (the "Change of Control Payment Date"). The notice, if sent prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 (the "<u>Exchange Act</u>") and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Securities, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the Securities by virtue of any such conflict.

------

This Security is one of a duly authorized issue of debt securities of the Company, issued and to be issued in one or more series under an Indenture, dated as of February 6, 2024 (herein called the "<u>Indenture</u>"), between the Company and U.S. Bank Trust Company, National Association, as Trustee (herein called the "<u>Trustee</u>", which term includes any successor Trustee under the Indenture), to which Indenture, all indentures supplemental thereto, and the Officer's Certificate dated November 3, 2025, setting forth the terms of the debt securities of this series, reference is hereby made for a statement of the respective rights, limitation of rights, duties, and immunities thereunder of the Company, the Trustee, and the Holders of the Securities (as defined below) and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of a series designated as 5.250% Notes due 2035 (the "<u>Securities</u>"). This Security is a Global Security representing a portion of the Securities, initially limited in aggregate principal amount to $750,000,000, but subject to the right of the Company to issue and sell additional Securities in the future without the consent of the Holders thereof. Any additional securities of this series, together with this Security, shall constitute a single series under the Indenture.

**<u>Optional Redemption</u>**

Prior to August 15, 2035 (the "Par Call Date"), the Company may redeem the Securities at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities 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 plus 20 basis points less (b) interest accrued to the Redemption Date, and (2) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date. In either case, the redemption is subject to the right of the Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or before the Redemption Date.

"Treasury Rate" means, with respect to any Redemption Date for the Securities, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily) - H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). 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 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 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. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the 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.

The Company's actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, the Trustee will have no duty to calculate the Redemption Price, nor will it have any duty to review or verify our calculations of the Redemption Price.

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

In the case of a partial redemption of the Securities, selection of the Securities 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 Securities of a principal amount of $2,000 or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption that relates to the Security will state the portion of the principal amount of the Security to be redeemed. A new Security in a principal amount equal to the unredeemed portion of the Security will be issued in the name of the Holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities are held by DTC (or another Depositary), the redemption of the Securities shall be done in accordance with the policies and procedures of the Depositary.

------

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

Subject to the provisions of Section 1102 of the Indenture, any such redemption may, at the Company's discretion, be conditioned upon (i) the occurrence of a Change of Control (as defined below) or (ii) the closing of another transaction, including a sale of securities or other financing, in each case as specified in the notice in reasonable detail.

**<u>Change of Control</u>**

Upon the occurrence of a Change of Control Triggering Event, unless the Company has otherwise exercised its right to redeem the Securities, each Holder of such Securities will have the right to require the Company to purchase all or a portion of such Holder's Securities pursuant to the offer described below (the "Change of Control Offer"), at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of purchase, subject to the rights of Holders of Securities on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date.

Within 30 days following the date upon which the Change of Control Triggering Event occurs, or at the Company's option, prior to any Change of Control but after the public announcement of the Change of Control, unless the Company has otherwise exercised its right to redeem the Securities, the Company will be required to deliver a notice to each Holder of Securities, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent, other than as may be required by law (the "Change of Control Payment Date"). The notice, if sent prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. Holders of Securities electing to have their Securities purchased pursuant to a Change of Control Offer must surrender their Securities, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Security completed, to the Paying Agent at the address specified in the notice, or transfer their Securities to the Paying Agent by book-entry transfer pursuant to the applicable procedures of DTC, before the close of business on the third Business Day prior to the Change of Control Payment Date.

The Company will not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times, and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer.

------

If Holders of not less than 90% in aggregate principal amount of the Outstanding Securities validly tender and do not withdraw the Securities in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company, purchases all of the Securities validly tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 10 nor more than 60 days' prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Securities that remain Outstanding following such purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest on the relevant Interest Payment Date).

The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 (the "<u>Exchange Act</u>") and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Securities, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the Securities by virtue of any such conflict.

If the Company receives such notice or has delivered such Company Order of the kind specified in clause (y) above, it may, in its sole discretion, designate a successor Depositary for such Global Security within 90 days after receiving such notice or delivery of such order, as the case may be. If the Company designates a successor Depositary as aforesaid, such Global Security shall promptly be exchanged in whole for one or more other Global Securities registered in the name of the successor Depositary, whereupon such designated successor shall be the Depositary for such successor Global Security or Global Securities. Securities so issued in exchange for this Global Security shall be of the same series and of like tenor, in authorized denominations and in the aggregate having the same principal amount as this Global Security and registered in such names as the Depositary for such Global Security shall direct.

Dear Ladies and Gentlemen:

We have acted as counsel for Southwest Airlines Co., a Texas corporation (the "<u>Company</u>"), with respect to certain legal matters in connection with the registration by the Company under the Securities Act of 1933 (the "<u>Securities Act</u>") of the offer and sale by the Company of $750,000,000 aggregate principal amount of 4.375% Notes due 2028 and $750,000,000 aggregate principal amount of 5.250% Notes due 2035 (together, the "<u>Notes</u>"), pursuant to the Underwriting Agreement, dated October 27, 2025 (the "<u>Underwriting Agreement</u>"), among the Company and BofA Securities, Inc., Citigroup Global Markets Inc., Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, and Morgan Stanley & Co. LLC, for themselves and as representatives of the underwriters party thereto (the "<u>Underwriters</u>").

The Notes have been offered for sale pursuant to a prospectus supplement, dated October 27, 2025, filed with the Securities and Exchange Commission (the "<u>Commission</u>") pursuant to Rule 424(b) on October 28, 2025, to the prospectus, dated February 7, 2024 (as amended and supplemented by the prospectus supplement, the "<u>Prospectus</u>"), that constitutes a part of the Company's Registration Statement on Form S-3 (Registration No. 333-276909), filed with the Commission on February 7, 2024 (the "<u>Registration Statement</u>"), which Registration Statement became effective upon filing with the Commission pursuant to Rule 462(e) under the Securities Act. The Notes will be issued under an indenture, dated as of February 6, 2024, between the Company and U.S. Bank Trust Company, National Association, as trustee (in such capacity, the "<u>Trustee</u>"), as supplemented by that certain officer's certificate of the Company, dated November 3, 2025, establishing the terms of each series of the Notes (together, the "<u>Indenture</u>").

We have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Company's Restated Certificate of Formation and the Fifth Amended and Restated Bylaws of the Company, (ii) certain resolutions adopted by the Board of Directors of the Company relating to the Registration Statement and related matters, (iii) certain resolutions adopted by the Pricing Committee of the Board of Directors of the Company relating to the issuance and sale of the Notes, (iv) the Registration Statement, (v) the Prospectus, (vi) the Indenture and (vii) such other certificates, instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed.
