------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) (i) Each document, if any, filed or to be filed pursuant to the Exchange Act and incorporated by reference in the Disclosure Package and the Prospectus, complied or will comply when so filed in all material respects with the Exchange Act and the rules and regulations of the Commission thereunder and will be timely filed as required thereby, (ii) each part of the Registration Statement, when such part became effective, did not contain and each such part, as amended or supplemented, if applicable, will not contain any 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, (iii) the Registration Statement, on the latest Effective Date, and the Prospectus, as of its date, complied and, as amended or supplemented, if applicable, will comply in all material respects with the Securities Act, the Exchange Act, the Trust Indenture Act of 1939, as amended (the "<u>Trust Indenture Act</u>") and the applicable rules and regulations of the Commission thereunder, (iv) the Prospectus, as of its date, did not contain and as of the Closing Date, as amended or supplemented, if applicable, will not contain any 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, in the light of the circumstances under which they were made, not misleading, and (v) the Disclosure Package, as of the Applicable Time of Sale, does 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; provided that the representations and warranties set forth in this Section 1(b) do not apply (x) to statements or omissions in the Registration Statement, the Disclosure Package or the Prospectus based upon information concerning the Underwriters furnished to the Company in writing by the Underwriters expressly for use therein, it being understood and agreed that the only such information furnished to the Company consists of the information described as such in Section 8(b) below, or (y) to that part of the Registration Statement that constitutes the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act, of the Trustee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Each Issuer Free Writing Prospectus and the final term sheet prepared and filed pursuant to Section 6(b) below does not include any information that conflicts with the information contained or incorporated by reference in the Registration Statement, including any prospectus supplement deemed to be a part thereof that has not been superseded or modified, it being understood and agreed that the foregoing does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by the Underwriters, it being understood and agreed that the only such information furnished to the Company by the Underwriters consists of the information described as such in Section 8(b) below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) (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 Securities 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) under the Securities Act) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Applicable Time of Sale (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" as defined in Rule 405 under the Securities Act. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) under the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Securities Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Each subsidiary of the Company that is a "significant subsidiary" as defined in Rule 405 under the Securities Act (a "<u>Significant Subsidiary</u>") has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Disclosure Package and the Prospectus, and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Indenture has been duly authorized, executed and delivered by the Company and, assuming the due authorization, execution and delivery by the Trustee, constitutes a valid and binding agreement of the Company enforceable in accordance with its terms except as the enforceability thereof may be limited by (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws affecting creditor's rights and remedies generally from time to time in effect and (ii) general principles of equity (whether considered in a proceeding in equity or at law) and an implied covenant of good faith and fair dealing (the "<u>Enforceability Exceptions</u>"). The Indenture has been duly qualified under the Trust Indenture Act and will conform in all material respects to the descriptions thereof in the Disclosure Package and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The Securities have been duly authorized and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and duly paid for by the Underwriters, as provided in this Agreement, will conform in all material respects to the descriptions thereof in the Disclosure Package and the Prospectus, will be entitled to the benefits of the Indenture and will be valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms except as the enforceability thereof may be limited by the Enforceability Exceptions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) The execution and delivery by the Company of, and the performance by the Company of its obligations under, this Agreement and the Indenture and the issuance and sale of the Securities by the Company will not (i) constitute a default under any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an "<u>Existing Instrument</u>"), (ii) result in any violation of the certificate of incorporation or bylaws of the Company, (iii) conflict with or constitute a breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company or any of its subsidiaries pursuant to any Existing Instrument or (iv) result in any violation of any law, regulation, judgment, order or decree of any governmental body,

------

agency or court having jurisdiction over the Company or any of its subsidiaries, except in each case of clauses (i), (iii) and (iv), for such defaults, conflicts, breaches, liens, charges, encumbrances or violations as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and, to the best of the Company's knowledge, no consent, approval or authorization of any governmental body or agency is required for the performance by the Company of its obligations under this Agreement, the Indenture or the Securities, except such as have been or will be obtained prior to the Closing Date under the Securities Act, the Exchange Act and the Trust Indenture Act and such as may be required under the securities or Blue Sky laws of the various states in connection with the offer and sale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) Since the date of the most recent audited financial statements in the Disclosure Package and the Prospectus, there has not been any material adverse change, or any development that would reasonably be expected to result in a material adverse change, in the financial condition, stockholders' equity, results of operations, business or properties of the Company and its subsidiaries, taken as a whole, whether or not arising in the ordinary course of business (referred to as a "<u>Material Adverse Change</u>" or "<u>Material Adverse Effect</u>") from that set forth in the Disclosure Package and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) There are no legal or governmental proceedings pending or, to the best of the Company's knowledge, threatened to which the Company or any of its subsidiaries is a party or to which any of the properties of the Company or any of its subsidiaries is subject that are required to be described in the Registration Statement or the Disclosure Package or the Prospectus and are not so described or, to the best of the Company's knowledge, any statutes, regulations, contracts or other documents that are required to be described in the Registration Statement, the Disclosure Package or the Prospectus or to be filed as an exhibit to the Registration Statement that are not described or filed as required.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) The Company and each of its Significant Subsidiaries have all necessary consents, authorizations, approvals, orders, certificates and permits of and from, and have made all declarations and filings with, all federal, state, local and other governmental authorities, all self-regulatory organizations and all courts and other tribunals, to own, lease, license and use its properties and assets and to conduct their business in the manner described in the Disclosure Package and the Prospectus, as then amended or supplemented, except to the extent that the failure to obtain or file would not reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o) Ernst & Young LLP, whose reports have been included or incorporated by reference in the Disclosure Package and the Prospectus, is an independent registered public accounting firm within the applicable rules and regulations adopted by the Commission and the Public Accounting Oversight Board (United States) and as required by the Securities Act and the rules and regulations thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p) The financial statements included or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus present fairly in all material respects the financial condition and results of operations of the Company and its subsidiaries taken as a whole, at the dates and for the periods indicated, and have been prepared in conformity with generally accepted accounting principles applied on a consistent basis throughout the periods involved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q) 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 Prospectus, the Company will not be required to register as, an "investment company" as such term is defined in the Investment Company Act of 1940, as amended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(r) The Company and its subsidiaries maintain a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) and are not aware of any material weakness in their internal controls over financial reporting.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(s) The Company and its subsidiaries maintain "disclosure controls and procedures" (as such term is defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures are effective.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(t) The Company will not use the proceeds of the sale of the Securities hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner, or other individual or entity directly or, to the knowledge of the Company, indirectly for the purpose of funding or facilitating any activities or business of or with any individual or entity (including ships or aircraft) (i) subject to sanctions administered or enforced by the U.S. government (including, without limitation, the Office of Foreign Assets Control of the U.S. Treasury Department or the U.S. Department of State and including, without limitation, the designation as a "specially designated national" or "blocked person"), the United Nations Security Council, the European Union, His Majesty's Treasury or other relevant sanctions authority (collectively, "Sanctions"), or (ii) in any country or territory, that, at the time of such funding or facilitation, is the subject of any Sanctions, including, without limitation, Cuba, Iran, North Korea, Crimea, the so-called Luhansk People's Republic, the so-called Donetsk People's Republic regions of Ukraine, and the non-Ukrainian government controlled areas of the Zaporizhzhia and Kherson regions of Ukraine (each, a "Sanctioned Territory").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Representatives shall have received on the date hereof and confirmed on the Closing Date (i) a letter dated the date hereof or the Closing Date, as applicable, in form and substance reasonably satisfactory to the Representatives, from Ernst & Young LLP, independent registered public accounting firm of the Company, and (ii) a letter dated the date hereof or the Closing Date, as applicable, in form and substance reasonably satisfactory to the Representatives, from KPMG LLP, independent registered public accounting firm of Wells Fargo Rail, each letter containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained in or incorporated by reference into the Registration Statement, the Disclosure Package and the Prospectus.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) If filing of the Prospectus, or any supplement thereto, is required pursuant to Rule 424(b) under the Securities Act, the Prospectus and any such supplement shall have been filed in the manner and within the time period required by Rule 424(b); the final term sheet contemplated by Section 6(b) hereof, and any other material required to be filed by the Company pursuant to Rule 433(d) under the Securities Act, shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433 under the Securities Act; and no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or, to the Company's knowledge, threatened.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. In further consideration of the agreements of the Underwriters contained in this Agreement, the Company covenants as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Prior to the termination of the offering of the Securities pursuant to this Agreement, the Company will not file any amendment or supplement to the Registration Statement or the Basic Prospectus (including any Prospectus Supplement relating to the Securities) unless the Company has previously furnished to the Representatives a copy thereof for its review and will not file any such proposed amendment or supplement to which the Representatives reasonably object; provided that the foregoing requirement shall not apply to any of the Company's periodic filings with the Commission required to be filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, which filings the Company will cause to be timely filed with the Commission and copies of which filings the Company will cause to be delivered to the Representatives upon written request therefor promptly after being filed with the Commission. Subject to the foregoing sentence, the Company will promptly cause each Prospectus Supplement to be filed with the Commission in accordance with Rule 424(b) under the Securities Act. The Company will promptly advise the Representatives (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) under the Securities Act, (ii) of the filing of any amendment or supplement to the Basic Prospectus, (iii) of the filing and effectiveness of any amendment to the Registration Statement, (iv) of any request by the Commission for any amendment of the Registration Statement, or for any amendment of or supplement to the Basic Prospectus or for any additional information, (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (vi) 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 initiation or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or notice of suspension of qualification and, if issued, to obtain as soon as possible the withdrawal of such stop order including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) To prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof in the form attached as Schedule III hereto, a copy of which shall be furnished to the Representatives for their review prior to filing. The Company will not file such term sheet without the approval of the Representatives, which approval shall not be unreasonably withheld. Upon receipt of such approval of the Representatives, the Company shall file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such Rule.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If, at any time prior to the filing of the Prospectus Supplement pursuant to Rule 424(b) under the Securities Act, 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 not misleading, the Company will (i) promptly notify the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) subject to the first clause of the first sentence of paragraph (a) of this Section 6, amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Representatives in such quantities as the Representatives may reasonably request.

&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 Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), or until the distribution of any Securities an Underwriter may own as principal has been completed, any event occurs or condition exists as a result of which (i) the Registration Statement or the Prospectus as then amended or supplemented would include an untrue statement of a material fact, or omit to state any 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 at such time, not misleading, or (ii) if, in the opinion of the Representatives or in the opinion of the Company, it is necessary at any time to amend or supplement the Registration Statement or the Prospectus, as then amended or supplemented, to comply with applicable law, the Company will immediately notify each Underwriter by telephone (with confirmation in writing) to suspend solicitation of offers to purchase Securities or any resale thereof and, if so notified by the Company, each Underwriter shall forthwith suspend such solicitation or resale and cease using the Prospectus as then amended or supplemented. The Company shall, at its expense, prepare and cause to be filed promptly with the Commission, subject to the first sentence of paragraph (a) of this Section 6, an amendment or supplement to the Registration Statement or Prospectus as then amended or supplemented that will correct such statement or omission or effect such compliance and will supply such amended or supplemented Prospectus to each Underwriter in such quantities as such Underwriter may reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company will make generally available to its security holders and to the Representatives as soon as practicable earnings statements that satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder covering the twelve-month period beginning, in each case, not later than the first day of the Company's fiscal quarter next following the date of the Underwriting Agreement. If such fiscal quarter is the last fiscal quarter of the Company's fiscal year, such earnings statement shall be made available not later than 90 days after the close of the period covered thereby and in all other cases shall be made available not later than 45 days after the close of the period covered thereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Company will furnish to the Representatives without charge three copies of the Registration Statement and all amendments thereto, including to the extent requested by the Representatives in writing, exhibits, schedules and any documents incorporated by reference therein, and, during the period mentioned in Section 6(d) above, as many copies of the Prospectus (including any preliminary prospectus) and each Issuer Free Writing Prospectus (and any supplements thereto), any documents incorporated by reference therein and any supplements and amendments thereto as the Representatives may reasonably request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The Company will qualify the Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and will pay all reasonable expenses (including fees and disbursements of counsel) in connection with such qualification and in connection with the determination of the eligibility of the Securities for investment under the laws of such jurisdictions as the Representatives may designate, provided that the Company shall not be obligated to so qualify the Securities if such qualification subjects it to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject, or requires it to file any general consent to service of process or qualify as a foreign corporation in any jurisdiction in which it is not so qualified.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Company agrees that, unless it has or shall have obtained the prior written consent (not to be unreasonably withheld) of the Representatives, 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 solely the information contained in the final term sheet prepared and filed pursuant to Section 6(b) hereto; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule IV hereto. Any such free writing prospectus consented to by the Representatives 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 under the Securities Act 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;(i) Prior to the termination of the offering of the Securities, the Company shall furnish to the Representatives such relevant documents and certificates of officers of the Company relating to the business, operations and affairs of the Company, the Registration Statement, the Basic Prospectus, any amendments or supplements thereto, the Indenture, the Securities, this Agreement, and the performance by the Company of its obligations hereunder or thereunder as the Representatives may from time to time reasonably request and shall notify the Representatives promptly in writing when it becomes aware of any downgrading or of its receipt of any notice of (i) any intended or potential downgrading or (ii) any review or possible change that does not indicate the direction of a possible change in the rating accorded any of the Company's securities by Moody's or S&P.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The Company will, whether or not any sale of Securities is consummated, pay all expenses incident to the performance of its obligations under the Underwriting Agreement, including: (i) the preparation and filing of the Registration Statement, any preliminary prospectuses, the Prospectus and each Issuer Free Writing Prospectus and all amendments and supplements thereto; (ii) the preparation, issuance and delivery of the Securities; (iii) the fees and disbursements of the Company's counsel and accountants and of the Trustee and its counsel; (iv) the qualification of the Securities under securities or Blue Sky laws in accordance with the provisions of Section 6(g), including filing fees and the reasonable fees and disbursements of the counsel for the Underwriters in connection therewith and in connection with the preparation of any Blue Sky memoranda ("<u>Blue Sky Memoranda</u>"); (v) the printing and delivery to the Underwriters in quantities as hereinabove stated of copies of the Registration Statement and all amendments thereto, the Basic Prospectus and any amendments or supplements thereto and each Issuer Free Writing Prospectus and any amendments or supplements thereto; (vi) the printing and delivery to the Underwriters of copies of the Indenture and any Blue Sky Memoranda; (vii) any fees charged by rating agencies for the rating of the Securities; (viii) any reasonable out-of-pocket expenses incurred by the Underwriters with the approval of the Company; and (ix) the fees and expenses, if any, incurred with respect to any filing with the Financial Industry Regulatory Authority, Inc.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) During the period beginning on the date of this Agreement and continuing to and including the Closing Date, the Company will not, without the prior consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any debt securities of the Company substantially similar to the Securities (other than (i) the Securities that are to be sold pursuant to this Agreement, (ii) other debt securities previously agreed to be sold by the Company and (iii) commercial paper issued in the ordinary course of business).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. (a) The Representatives shall promptly notify the Company of the completion of the distribution of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter, severally and not jointly, agrees with the Company that, unless it has or shall have obtained, 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 solely the information contained in the final term sheet prepared and filed pursuant to Section 6(b) hereto; provided that the prior written consent of the Company shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule IV hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. (a) The Company agrees to indemnify and hold harmless each Underwriter, the officers, directors, employees and agents of such Underwriter, and each person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages or liabilities, joint or several, caused by or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or in any amendment thereof, or in the Prospectus, any preliminary prospectus, any Permitted Free Writing Prospectus or other free writing prospectus used by the Company or any agent of the Company (other than any Underwriter) or the information contained in the final term sheet as required to be prepared and filed pursuant to Section 6(b) hereof, or in any amendment or supplement to any 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, except insofar as such losses, claims, damages or liabilities are caused by or based upon any such untrue statement or omission or alleged untrue statement or alleged omission based upon information furnished to the Company in writing by or on behalf of such Underwriter expressly for use therein.

&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, its officers who sign the Registration Statement and any person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each such Underwriter, but only with reference to information relating to such Underwriter furnished in writing by such Underwriter expressly for use in the Registration Statement or the Prospectus or any amendments or supplements thereto or in any preliminary prospectus or Permitted Free Writing Prospectus. The Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities and under the heading "Underwriting," in (i) the third paragraph related to discounts, (ii) the fifth paragraph related to stabilization, overallotment, concessions and syndicate covering transactions and (iii) the second and the fourth sentences of the sixth paragraph related to market making activities in the preliminary prospectus constitute the only information furnished by or on behalf of the several Underwriters for inclusion in the Registration Statement, the Prospectus, any amendments or supplements thereto or in any preliminary prospectus or Permitted Free Writing Prospectus.

&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; and the indemnifying party, upon request of the indemnified party, shall 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 shall pay the reasonable 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 actual or potential parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified 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 use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest or (iv) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such proceeding. It is understood that the indemnifying party shall not, 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. Such firm shall be designated in writing by the Representatives, 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 an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel as contemplated by the third sentence 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 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 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. Failure to notify the indemnifying party as required by the first sentence of this paragraph (c) (1) will not relieve the indemnifying party from liability 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 (2) 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If the indemnification provided for in paragraph (a) or (b) of this Section 8 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein in connection with any offering of Securities, then the Company and the Underwriters severally agree that each 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 from the offering of the Securities 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 of the Underwriters on the other in connection with the statements or omissions which 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 in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Securities (before deducting expenses) received by the Company and the total discounts and commissions received by the Underwriters in respect thereof, in each case as set forth in the Prospectus, bear to the total aggregate

------

public offering price of such Securities; provided, however, 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. The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or allegedly untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the considerations referred to in the immediately preceding paragraph. 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. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The 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.

The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company in this Agreement shall remain operative and in full force and effect regardless of (i) termination of this Agreement, (ii) any investigation made by any Underwriter or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its directors or officers or any person controlling the Company and (iii) acceptance of and payment for any of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. 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 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 the Underwriting Agreement 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; provided, however, 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 the Underwriting Agreement, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities. If arrangements satisfactory to the non-defaulting Underwriters and the Company for the purchase of at least 90% of the aggregate principal amount of the Securities are not made within 36 hours after such default or if such non- defaulting Underwriters do not agree to purchase at least 90% of the aggregate principal amount of such Securities, this Agreement will terminate without liability to any non-defaulting Underwriter or the Company; provided, however, that if such non-defaulting Underwriters agree to purchase at least 90% but less than 100% of the aggregate principal amount of such Securities, the Company, at its option, may terminate this Agreement and no non-defaulting Underwriter or the Company shall have any liability in connection therewith. 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 shall determine in order that the required changes in the Registration Statement and the 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 non-defaulting Underwriter for damages occasioned by its default hereunder.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company, if prior to the Closing Date (i) trading in securities generally on the New York Stock Exchange, the Nasdaq Global Market or the Chicago Stock Exchange shall have been suspended or materially limited, (ii) a general moratorium on commercial banking activities in New York shall have been declared by either federal or New York State authorities, (iii) there shall have occurred a material disruption in securities settlement, payment or clearance services in the United States or (iv) there shall have occurred any material outbreak or escalation of hostilities or other calamity or crisis and, in the case of any of the events described in clauses (i) through (iv) above, the effect of such event on the financial markets of the United States, in the reasonable judgment of the Representatives, is so material and adverse that it is impractical to market the Securities on the terms and in the manner contemplated by the Disclosure Package and the Prospectus (exclusive of any amendment of supplement thereto).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. If this Agreement shall be terminated by the Underwriters or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement except pursuant to Section 9 hereof, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally through the Representatives on demand, for all out-of-pocket expenses (including the reasonable fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;14. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to a contract executed and performed in such State without giving effect to the conflicts of laws principles thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;15. 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;16. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) For purposes of this provision:

&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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) a "BHC Act Affiliate" has the meaning assigned to the term "affiliate" in, and shall be interpreted in accordance with, 12 U.S.C. §1841(k);

&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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) a "Covered Entity" means any of the following: (A) a "covered entity" as that term is defined in, and interpreted in accordance with, 12 C.F.R. §252.82(b); (B) "covered bank" as that term is defined in, and interpreted in accordance with, 12 C.F.R. §47.3(b); or (C) a "covered FSI" as that term is defined in, and interpreted in accordance with, 12 C.F.R. §382.2(b);

&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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) "Default Right" has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§252.81, 47.2 or 382.1, as applicable; 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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) "U.S. Special Resolution Regime" means each of (A) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (B) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

GATX CORPORATION

This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of February 6, 2008 (herein called the "Indenture"), between the Company and U.S. Bank Trust Company, National Association, as trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), as successor in interest to U.S. Bank National Association, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially issued in an aggregate principal amount of $500,000,000 on February 6, 2025 and currently limited in aggregate principal amount to $700,000,000.

The Securities are redeemable at the option of the Company, in whole at any time or in part, from time to time, at a Redemption Price equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 100% of the aggregate principal amount of such Securities to be redeemed; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities
being redeemed, assuming that the Securities to be redeemed matured on the Par Call Date (as defined below), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as defined below), plus 20 basis points, less (b) interest accrued to the redemption date.

Notwithstanding the foregoing, if the Securities are redeemed on or after March 15, 2035 (the "Par Call Date"), the Redemption Price will be 100% of the principal amount of the Securities to be redeemed.

In each case, the Company will pay accrued and unpaid interest on the principal amount being redeemed to, but excluding, the redemption date.

Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on such interest payment date, to the registered holders as of the close of business on the relevant record date in accordance with the Securities and the Indenture.

The Company may at any time, and from time to time, purchase the Securities at any price or prices in the open market or otherwise.

The Treasury Rate will be determined by the Company or its designee (which will not be the Trustee) 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 or its designee will 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 will 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 will 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 or its designee will 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, as applicable. 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 or its designee will 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, then the Company or its designee will 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 will 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 will provide notice of a redemption to holders of Securities to be redeemed at least 10 and not more than 60 days prior to the date fixed for redemption. If fewer than all of the Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the redemption date, the particular Securities or portions thereof for redemption from the outstanding Securities not previously called by such method as the Trustee deems fair and appropriate.

------

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Upon the occurrence of a Change of Control Repurchase Event, unless the Company has exercised its right to redeem the Securities as described above, each holder of the 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, if any, to the date of purchase, subject to the rights of holders of the Securities on the relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the Change of Control Repurchase Event occurred, or at the Company's option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to provide a notice to each holder of the 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 provided, other than as may be required by law (the "Change of Control Payment Date"). The notice, if provided 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 being consummated on or prior to the Change of Control Payment Date.

Holders of the Securities electing to have Securities purchased pursuant to a Change of Control Offer will be required to 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 the paying agent, prior to 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.

"Below Investment Grade Rating Event" means the rating on the Securities is lowered by each of the Rating Agencies and the Securities are rated Below Investment Grade by each of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Securities is under publicly announced consideration for possible downgrade by any of the Rating Agencies); *provided* that a Below

------

Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if any of the Rating Agencies making the reduction in rating to which this definition would otherwise apply does not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

"Change of Control" means the occurrence of any one of the following:

Exchange Act of 1934, as amended (the "Exchange Act")) other than to the Company or one of its subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the consummation of any transaction (including without limitation, any merger or consolidation) the result of
which is that any "person" (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the "beneficial owner" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company, measured by voting power rather than number of shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges
with or into, the Company, in any such event pursuant to a transaction in which any of the Company's outstanding Voting Stock or that of such other Person is converted into or exchanged for cash, securities or other property, other than any
such transaction where the shares of the Company's Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving Person immediately after
giving effect to such transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the first day on which the majority of the members of the Company's board of directors cease to be
Continuing Directors; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the adoption of a plan relating to the Company's liquidation or dissolution.

"Change of Control Repurchase Event" means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• was a member of the Company's board of directors on the date of the Indenture; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• was nominated for election or elected to the Company's board of directors with the approval of a majority
of the Continuing Directors who were members of such board of directors at the time of such nomination or election.

"Investment Grade" means a rating of Baa3 or better by Moody's (or its equivalent under any successor rating category of Moody's), and a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P).

"Moody's" means Moody's Investors Service, Inc., a subsidiary of Moody's Corporation, and its successors.

"S&P" means S&P Global Ratings, a division of S&P Global, Inc., and its successors.

"Rating Agency" means each of Moody's and S&P; *provided,* that if either of Moody's or S&P ceases to provide rating services to issuers or investors, the Company may appoint a replacement for such Rating Agency that is reasonably acceptable to the Trustee under the Indenture.

"Voting Stock" of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

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

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

------

"Global Security" and "Global Securities" means a Security or Securities evidencing all or part of a series of Securities, issued to the Depositary (as hereinafter defined) for such series or its nominee, and registered in the name of such Depositary or its nominee. "Depositary" means, with respect to the Securities of any series issuable or issued in whole or in part in the form of one or more Global Securities, the person designated as the Depositary by the Company.

No holder of any beneficial interest in this Security held on its behalf by a Depositary or a nominee of such Depositary shall have any rights under the Indenture with respect to such Global Security, and such Depositary or nominee may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall impair, as between a Depositary and such holders of beneficial interests, the operation of customary practices governing the exercise of the rights of the Depositary as Holder of any Security.

This Security is exchangeable, in whole but not in part, for Securities registered in the names of Persons other than the Depositary or its nominee or in the name of a successor to the Depositary or a nominee of such successor depositary only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for this Security or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, a successor depositary is not appointed by the Company within 90 days, (ii) the Company in its discretion at any time determines not to have all of the Securities of this series represented by one or more Global Security or Securities and notifies the Trustee thereof, or (iii) an Event of Default has occurred and is continuing with respect to the Securities of this series. If this Security is exchangeable pursuant to the preceding sentence, it shall be exchangeable for Securities issuable in authorized denominations and registered in such names as the Depositary holding this Security shall direct. Subject to the foregoing, this Security is not exchangeable, except for a Security or Securities of the same aggregate denominations to be registered in the name of such Depositary or its nominee or in the name of a successor to the Depositary or a nominee of such successor depositary.

No recourse shall be had for the payment of the principal of (and premium, if any, on) or interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

All capitalized terms used in this Security and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

This Security, including without limitation the obligation of the Company contained herein to pay the principal of (and premium, if any, on) and interest on this Security in accordance with the terms hereof and of the Indenture, shall be construed in accordance with and governed by the laws of the State of New York.

GATX CORPORATION

This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of February 6, 2008 (herein called the "Indenture"), between the Company and U.S. Bank Trust Company, National Association, as trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture), as successor in interest to U.S. Bank National Association, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially issued in an aggregate principal amount of $400,000,000 on June 5, 2024 and further issued in an aggregate principal amount of $300,000,000 on February 6, 2025 and currently limited in aggregate principal amount to $900,000,000.

The Securities are redeemable at the option of the Company, in whole at any time or in part, from time to time, at a Redemption Price equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 100% of the aggregate principal amount of such Securities to be redeemed; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities
being redeemed, assuming that the Securities to be redeemed matured on the Par Call Date (as defined below), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, less (b) interest accrued to the redemption date.

Notwithstanding the foregoing, if the Securities are redeemed on or after December 5, 2053 (the "Par Call Date"), the Redemption Price will be 100% of the principal amount of the Securities to be redeemed.

In each case, the Company will pay accrued and unpaid interest on the principal amount being redeemed to, but excluding, the redemption date.

Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on such interest payment date, to the registered holders as of the close of business on the relevant record date in accordance with the Securities and the Indenture.

The Company may at any time, and from time to time, purchase the Securities at any price or prices in the open market or otherwise.

The Treasury Rate will be determined by the Company or its designee (which will not be the Trustee) 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 or its designee will 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 will 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 will 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 or its designee will 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, as applicable. 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 or its designee will 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, then the Company or its designee will 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 will 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 will provide notice of a redemption to holders of Securities to be redeemed at least 10 and not more than 60 days prior to the date fixed for redemption. If fewer than all of the Securities are to be redeemed, the Trustee will select, not more than 60 days prior to the redemption date, the particular Securities or portions thereof for redemption from the outstanding Securities not previously called by such method as the Trustee deems fair and appropriate.

------

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Upon the occurrence of a Change of Control Repurchase Event, unless the Company has exercised its right to redeem the Securities as described above, each holder of the 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, if any, to the date of purchase, subject to the rights of holders of the Securities on the relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the Change of Control Repurchase Event occurred, or at the Company's option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to provide a notice to each holder of the 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 provided, other than as may be required by law (the "Change of Control Payment Date"). The notice, if provided 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 being consummated on or prior to the Change of Control Payment Date.

Holders of the Securities electing to have Securities purchased pursuant to a Change of Control Offer will be required to 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 the paying agent, prior to 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.

be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if any of the Rating Agencies making the reduction in rating to which this definition would otherwise apply does not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

"Change of Control" means the occurrence of any one of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the consummation of any transaction (including without limitation, any merger or consolidation) the result of
which is that any "person" (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the "beneficial owner" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company, measured by voting power rather than number of shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges
with or into, the Company, in any such event pursuant to a transaction in which any of the Company's outstanding Voting Stock or that of such other Person is converted into or exchanged for cash, securities or other property, other than any
such transaction where the shares of the Company's Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving Person immediately after
giving effect to such transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the first day on which the majority of the members of the Company's board of directors cease to be
Continuing Directors; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the adoption of a plan relating to the Company's liquidation or dissolution.

of the Continuing Directors who were members of such board of directors at the time of such nomination or election.

"Moody's" means Moody's Investors Service, Inc., a subsidiary of Moody's Corporation, and its successors.

"S&P" means S&P Global Ratings, a division of S&P Global, Inc., and its successors.

"Rating Agency" means each of Moody's and S&P; *provided,* that if either of Moody's or S&P ceases to provide rating services to issuers or investors, the Company may appoint a replacement for such Rating Agency that is reasonably acceptable to the Trustee under the Indenture.

"Voting Stock" of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

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

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any, on) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

"Depositary" means, with respect to the Securities of any series issuable or issued in whole or in part in the form of one or more Global Securities, the person designated as the Depositary by the Company.

------

No holder of any beneficial interest in this Security held on its behalf by a Depositary or a nominee of such Depositary shall have any rights under the Indenture with respect to such Global Security, and such Depositary or nominee may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall impair, as between a Depositary and such holders of beneficial interests, the operation of customary practices governing the exercise of the rights of the Depositary as Holder of any Security.

This Security is exchangeable, in whole but not in part, for Securities registered in the names of Persons other than the Depositary or its nominee or in the name of a successor to the Depositary or a nominee of such successor depositary only if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for this Security or if at any time such Depositary ceases to be a clearing agency registered under the Exchange Act, and, in either case, a successor depositary is not appointed by the Company within 90 days, (ii) the Company in its discretion at any time determines not to have all of the Securities of this series represented by one or more Global Security or Securities and notifies the Trustee thereof, or (iii) an Event of Default has occurred and is continuing with respect to the Securities of this series. If this Security is exchangeable pursuant to the preceding sentence, it shall be exchangeable for Securities issuable in authorized denominations and registered in such names as the Depositary holding this Security shall direct. Subject to the foregoing, this Security is not exchangeable, except for a Security or Securities of the same aggregate denominations to be registered in the name of such Depositary or its nominee or in the name of a successor to the Depositary or a nominee of such successor depositary.

No recourse shall be had for the payment of the principal of (and premium, if any, on) or interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

All capitalized terms used in this Security and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

This Security, including without limitation the obligation of the Company contained herein to pay the principal of (and premium, if any, on) and interest on this Security in accordance with the terms hereof and of the Indenture, shall be construed in accordance with and governed by the laws of the State of New York.

Ladies and Gentlemen:

We have acted as counsel to GATX Corporation, a New York corporation ("GATX" or the "Company"), in connection with an offering by GATX pursuant to Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"), of $200,000,000 aggregate principal amount of the Company's 5.500% Senior Notes due 2035 (the "2035 Notes") and $200,000,000 aggregate principal amount of the Company's 6.050% Senior Notes due 2054 (the "2054 Notes" and, together with the 2035 Notes, the "Notes"). The Notes are to be issued under the Indenture, dated as of February 6, 2008, between GATX and U.S. Bank Trust Company, National Association, as Trustee, as successor in interest to U.S. Bank National Association (the "Indenture"). The Notes are subject to the Underwriting Agreement (the "Underwriting Agreement"), dated October 22, 2025, between GATX and BofA Securities, Inc., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, as representatives of the several underwriters listed therein. The 2035 Notes will form a single series with the 5.500% Senior Notes due 2035 issued on February 6, 2025. Upon completion of the offering, an aggregate principal amount of $700,000,000 of the 2035 Notes will be outstanding. The 2054 Notes will form a single series with the 6.050% Senior Notes due 2054 issued on June 5, 2024 and February 6, 2025. Upon completion of the offering, an aggregate principal amount of $900,000,000 of the 2054 Notes will be outstanding.

We have also participated in the preparation and filing with the Securities and Exchange Commission under the Securities Act of a Registration Statement on Form S-3, as amended (File No. 333-286436) (the "Registration Statement"), relating to the Notes. In rendering our opinions set forth below, we have examined originals or copies identified to our satisfaction of (i) the Underwriting Agreement; (ii) the Registration Statement; (iii) the prospectus as supplemented relating to the Notes; (iv) the Indenture; (v) the form of the Notes; and (vi) officers' certificates establishing the terms of the Notes pursuant to the Indenture. The Notes are registered on the Registration Statement. In addition, we have examined and relied upon other documents, certificates, corporate records, opinions and instruments, obtained from GATX or other sources believed by us to be reliable, as we have deemed necessary or appropriate for the purpose of this opinion.

In expressing the opinions set forth below, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, conformed or photostatic copies and the legal competence of each individual executing any document. As to all parties, we have assumed the due authorization, execution and delivery of all documents and the validity and enforceability thereof against all parties thereto, other than GATX, in accordance with their respective terms.

Mayer Brown is a global services provider comprising an association of legal practices that are separate entities including

As to matters of fact (but not as to legal conclusions), to the extent we deemed proper, we have relied on certificates of responsible officers of GATX and of public officials and on the representations, warranties and agreements of GATX contained in the Underwriting Agreement.

Based upon and subject to the foregoing and to the assumptions, conditions and limitations set forth herein, and assuming that the Notes are issued in accordance with the terms of the Underwriting Agreement, we are of the opinion that the Notes constitute valid and legally binding obligations of GATX entitled to the benefits of the Indenture, except that the enforceability thereof may be subject to (i) bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws now or hereafter in effect relating to or affecting creditors' rights or remedies generally and (ii) general principles of equity and to the discretion of the court before which any proceedings therefor may be brought (regardless of whether enforcement is sought in a proceeding at law or in equity).

We are admitted to practice law in the State of New York and our opinions expressed herein are limited solely to the federal laws of the United States of America and the laws of the State of New York, and we express no opinion herein concerning the laws of any other jurisdiction.

This opinion and the statements expressed herein are as of the date hereof. We assume no obligation to update or supplement this opinion letter to reflect any facts or circumstances that may hereafter come to our attention or any changes in applicable law which may hereafter occur.

We hereby consent to the incorporation by reference of this opinion as an exhibit to the Registration Statement and to all references to this firm in such Registration Statement. In giving this consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act, or the rules and regulations of the Securities and Exchange Commission.
