To the addressees set forth above:

HF Sinclair Corporation, a Delaware corporation (the "**Company**"), agrees with you as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. <u>Issuance of Securities</u>. The Company proposes to issue and sell to Citigroup Global Markets Inc., Scotia Capital (USA) Inc., TD Securities (USA) LLC and Truist Securities, Inc. (the "**Representatives**") and the other underwriters listed on <u>Schedule I</u> attached hereto (together with the Representatives, the "**Underwriters**"), for whom you are acting as representatives, $500,000,000 aggregate principal amount of its 5.500% Senior Notes due 2032 (the "**Securities**"). The Securities will be issued pursuant to the indenture dated April 27, 2022 (the "**Base Indenture**"), as supplemented and amended by a fourth supplemental indenture to be dated August 18, 2025 (the "**Fourth Supplemental Indenture**" and, together with the Base Indenture, as so supplemented and amended, the "**Indenture**"), each by and between the Company and Computershare Trust Company, N.A., as trustee (the "**Trustee**"). Certain terms used in this underwriting agreement (this "**Agreement**") are defined in Section 13 hereof.

------

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

The Company has prepared and previously filed with the Securities and Exchange Commission (the "**Commission**") an "automatic shelf registration statement," as defined under Rule 405 on Form S-3 (File No. 333-285291) covering the public offering and sale of certain securities of the Company, including the Securities, under the 1933 Act and the rules and the 1933 Act Regulations, which automatic shelf registration statement became effective under Rule 462(e) of the 1933 Act Regulations. The Company has also prepared and previously filed with the Commission a preliminary prospectus supplement dated August 11, 2025 relating to the Securities and a related prospectus dated February 26, 2025 (the "**Base Prospectus**"). Such preliminary prospectus supplement and Base Prospectus, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are hereinafter called, collectively, the "**Pre-Pricing Prospectus**." Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a prospectus supplement dated August 11, 2025 (the "**Prospectus Supplement**"). The filing of any preliminary prospectus by the Company with the Commission was, and the filing of the Prospectus Supplement and the Base Prospectus by the Company with the Commission will be, in accordance with the provisions of Rule 430B and Rule 424(b), and the Company has previously advised you of all information (financial and otherwise) that will be set forth therein. The Prospectus Supplement and the Base Prospectus, in the form first furnished to the Underwriters for use in connection with the Offering (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are herein called, collectively, the "**Prospectus**."

This Agreement, the Securities and the Indenture are hereinafter referred to collectively as the "**Note Documents**." The issuance and sale of the Securities is referred to as the "**Offering**."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. <u>Agreements to Sell and Purchase</u>*.* On the basis of the representations, warranties and covenants contained in this Agreement, the Company agrees to issue and sell to the Underwriters, and on the basis of the representations, warranties and covenants contained in this Agreement, and subject to the terms and conditions contained in this Agreement, each of the Underwriters, severally and not jointly, agrees to purchase from the Company the aggregate principal amount of Securities set forth opposite its name on <u>Schedule I</u> attached hereto. The purchase price for the Securities shall be 98.665% of such principal amount, plus accrued interest, if any, from August 18, 2025 to the Closing Date (as defined below). The Company will not be obligated to deliver any of the Securities except upon payment for all of the Securities to be purchased as provided herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. <u>Delivery and Payment</u>*.* Delivery of, and payment of the purchase price for, the Securities shall be made at 10:00 a.m., New York time, on August 18, 2025, unless postponed in accordance with the provisions of Section 11(e) hereof (such date and time, the "**Closing Date**"), at the offices of Latham & Watkins LLP, 1271 Avenue of the Americas, New York, New York 10020. The Closing Date and the location of delivery of and the form of payment for the Securities may be varied by mutual agreement between the Underwriters and the Company.

------

The Securities shall be delivered by the Company to the Underwriters (or as the Underwriters direct) through the facilities of The Depository Trust Company ("**DTC**") against payment by the Underwriters of the purchase price therefor by means of wire transfer of immediately available funds to such account or accounts specified by the Company in accordance with Section 8(h) on or prior to the Closing Date, or by such means as the parties hereto shall agree prior to the Closing Date. It is understood that each Underwriter has authorized the Representatives for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Securities which it has agreed to purchase. Citigroup Global Markets Inc., individually and not as a representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Securities to be purchased by any Underwriter whose funds have not been received by the Closing Date, but such payment shall not relieve such Underwriter from its obligations hereunder. The Securities shall be evidenced by one or more certificates in global form registered in the name of Cede & Co., as nominee of DTC, and having an aggregate principal amount corresponding to the aggregate principal amount of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. <u>Agreements of the Company</u>. The Company covenants and agrees with the Underwriters as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company, subject to Section 4(b) hereof, will comply with the requirements of Rule 430B with respect to the Prospectus and Rule 433 with respect to any Issuer Free Writing Prospectus, and will notify the Representatives immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or when any preliminary prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement to any of the foregoing shall have been filed, (ii) of the receipt of any comments from the Commission (and shall promptly furnish the Representatives with a copy of any comment letters and any transcript of oral comments, and shall furnish the Representatives with copies of any written responses thereto a reasonable amount of time prior to the proposed filing thereof with the Commission and will not file any such response to which the Representatives or counsel for the Underwriters shall object), (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus or the Prospectus or any Issuer Free Writing Prospectus or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement to any of the foregoing or any notice from the Commission objecting to the use of the form of the Registration Statement or any post-effective amendment thereto, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction or of the loss or suspension of any exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the Offering. The Company will make every reasonable effort to prevent the issuance of any stop order and the suspension or loss of any qualification of the Securities for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued, or any such suspension or loss occurs, to obtain the lifting thereof at the earliest possible moment. The Company shall pay the required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1)(i) of the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the 1993 Act Regulations, except to the extent such filing fees have been paid prior to the date hereof.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) From the Applicable Time through the Closing Date (or, if later, through the end of the period (the "**Prospectus Delivery Period**") during which the Prospectus is required (or, but for the provisions of Rule 172, would be required) to be delivered by applicable law (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise)), the Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement, any Issuer Free Writing Prospectus or any amendment, supplement or revision to any preliminary prospectus, the Prospectus or any Issuer Free Writing Prospectus, whether pursuant to the 1933 Act or otherwise, and the Company will furnish the Representatives with electronic copies of any such documents within a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object. The Company has given the Representatives notice of any filings made pursuant to the 1934 Act or the 1934 Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time through the Closing Date (or, if later, through the end of the Prospectus Delivery Period) and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company has furnished or will deliver upon request to the Representatives and counsel for the Underwriters, without charge, electronic copies of the Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and electronic copies of all consents and certificates of experts. The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Company has delivered to each Underwriter, without charge, electronic copies of each preliminary prospectus and any amendments or supplements thereto, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the Prospectus Delivery Period to be delivered by applicable law (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), electronic copies of the Pre-Pricing Prospectus and any Issuer Free Writing Prospectus, and such number of printed copies of the Prospectus, and any amendments or supplements to any of the foregoing, as such Underwriter may reasonably request. Each preliminary prospectus, the Prospectus, each Issuer Free Writing Prospectus and any amendments or supplements to any of the foregoing furnished to the Underwriters were and will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Following the execution of this Agreement, the Company will, subject to Section 4(b) hereof, prepare the Prospectus, which shall contain the public offering price and terms of the Securities, the plan of distribution thereof and such other information as may be required by the 1933 Act or the 1933 Act Regulations or as the Representatives and the Company may deem appropriate, and will file or transmit for filing with the Commission, in accordance with the provisions of Rule 430B and in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), the Prospectus.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Company will comply with the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated by this Agreement, the General Disclosure Package (as defined below) and the Prospectus. If at any time during the Prospectus Delivery Period, any event shall occur or condition shall exist as a result of which it is necessary (or if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) so that the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or if it is necessary (or, if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus (or, in each case, any documents incorporated or deemed to be incorporated by reference therein) in order to comply with the requirements of the 1933 Act, the 1933 Act Regulations, the 1934 Act or the 1934 Act Regulations, the Company will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement (or, if the Representatives or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representatives of its intention to prepare such amendment or supplement) and will promptly prepare and file with the Commission, subject to Section 4(b) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or post-effective amendment to the Registration Statement, the Company will use its best efforts to have such amendment declared or become effective as soon as practicable and the Company will furnish to the Underwriters electronic copies of such amendment or supplement. If at any time an Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary (or if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend or supplement such Issuer Free Writing Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary (or, if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement (or, if the Representatives or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representatives of its intention to prepare such amendment or supplement) and will promptly prepare and, if required by the 1933 Act or the 1933 Act Regulations, file with the Commission, subject to Section 4(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company will furnish to the Underwriters electronic copies of such amendment or supplement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The Company will qualify or register the Securities for offering and sale, or obtain an exemption for the Securities to be offered and sold, under the securities laws of such jurisdictions as the Underwriters may request and to continue such qualification or exemption in effect so long as required for the distribution of the Securities. Notwithstanding the foregoing, the Company shall not be required to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to execute a general consent to service of process in any such jurisdiction or subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) (A) At the respective times the Registration Statement or any amendments thereto were filed with the Commission, (B) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at any time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption of Rule 163 and (D) at the date hereof, the Company was and is a "well-known seasoned issuer" as defined in Rule 405. The Registration Statement is an "automatic shelf registration statement," as defined in Rule 405 and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on such an "automatic shelf registration statement." The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of an automatic shelf registration statement. Any written communication that was an offer relating to the Securities made by the Company or any person acting on its behalf (within the meaning, for this sentence only, of Rule 163(c)) prior to the filing of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) The Company meets the requirements for use of Form S-3 under the 1933 Act and the Securities have been duly registered under the 1933 Act pursuant to the Registration Statement. The Registration Statement and any post-effective amendments thereto have become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. The Registration Statement was initially filed with the Commission on February 26, 2025.

Each preliminary prospectus and the Prospectus and any amendments or supplements to any of the foregoing filed as part of the Registration Statement or any amendment thereto, filed pursuant to Rule 424 under the 1933 Act, or delivered to the Underwriters for use in connection with the Offering, complied when so filed or when so delivered, as the case may be, in all material respects with the 1933 Act and the 1933 Act Regulations.

For purposes of this Agreement, references to the "delivery" or "furnishing" of any of the foregoing documents to the Underwriters, and any similar terms, include, without limitation, electronic delivery.

Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offering and sale of the Securities did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any preliminary prospectus or the Prospectus that has not been superseded or modified.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) The documents incorporated or deemed to be incorporated by reference in the Registration Statement, any preliminary prospectus and the Prospectus, at the respective times when they became or hereafter become effective or at the respective times they were or hereafter are filed with the Commission, as the case may be, conformed, and any documents so filed and incorporated by reference after the date of this Agreement and on or prior to the Closing Date will conform, when they are filed with the Commission, in all material respects to the requirements of the 1934 Act and the 1934 Act Regulations, and none of such incorporated documents contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and any further documents so filed and incorporated by reference in the Registration Statement, any preliminary prospectus and the Prospectus, when such documents become effective or are filed with the Commission, as the case may be, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

A "**Material Adverse Effect**" means (x) a material adverse effect on the business, condition (financial or otherwise), results of operations or properties of the Company and its Subsidiaries, taken as a whole or (y) a material adverse effect on the ability to consummate the Offering.

The Indenture conforms in all material respects to the description thereof in the Registration Statement, the General Disclosure Package and the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) The Securities have been duly and validly authorized for issuance and sale by the Company, and when issued by the Company, authenticated by the Trustee and delivered against payment therefor by the Underwriters in accordance with the terms of this Agreement and the Indenture, the Securities will be legally binding and valid obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by the Bankruptcy Exceptions.

To the knowledge of the Company, no third party to any indenture, mortgage, deed of trust, loan agreement or other agreement to which the Company or any of its Subsidiaries is a party or by which any of them is bound or to which any of their properties is subject, is in default under any such agreement, which breach, default or violation would, if continued, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xiii) No consent, approval, authorization, order, registration, filing or qualification of or with any court, governmental agency or body is required for the offering, issuance and sale by the Company of the Securities, the execution, delivery and performance of this Agreement and the Note Documents by the Company, or the consummation by the Company of the transactions contemplated hereby and thereby, except for (i) such consents, approvals, authorizations, orders, registrations, filings or qualifications as are required (a) under the 1933 Act, the 1933 Act Regulations, the 1934 Act, the 1934 Act Regulations or the 1939 Act and have been obtained or made (except for the filing of the Prospectus and the Pricing Term Sheet pursuant to Rules 424(b) and 433, respectively), and (b) under state securities or "Blue Sky" laws, and (ii) such consents which, if not obtained would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxiv) Neither the Company nor its Subsidiaries has any liability for, or knowledge of any existing circumstances that could reasonably be expected to result in, any prohibited transaction (within the meaning of Section 406 of the Employee Retirement Income Security Act of 1974, as amended, "**ERISA**"), any failure to meet the minimum funding standard set forth in Sections 412 of the Internal Revenue Code (the "**Code**") and 303 of ERISA, whether or not waived, any unpaid minimum required contribution under Sections 302 and 303 of ERISA or Sections 412 and 430 of the Code, or any tax resulting from failure to pay any such minimum required contributions under Section 4971 of the Code, or any complete or partial withdrawal liability with respect to any pension, profit sharing or other plan which is subject to ERISA, to which the Company or any of its Subsidiaries makes or has ever been required to make any contributions or has any liability whether absolute or contingent (the "**Plans**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxvi) The statements in the Pre-Pricing Prospectus and the Prospectus under the headings "Material United States Federal Income Tax Consequences," "Description of Debt Securities" and "Description of Notes" fairly summarize the matters therein described in all material respects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxvii) Neither the Company nor any of its Subsidiaries nor, to the best knowledge of the Company, any director, officer, agent, employee, affiliate or other person associated with or acting on behalf of the Company or any of its Subsidiaries has (i) used any funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) made or taken any act in furtherance of an offer, promise or authorization of any direct or indirect unlawful payment to any foreign or domestic government or regulatory official or employee, including of any government-owned or controlled entity or of a public international organization, or any person acting in an official capacity for or on behalf of any of the foregoing, or any political party or party official or candidate for political office; (iii) violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, as amended, or any applicable law or regulation implementing the OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transaction, or committed an offense under the Bribery Act 2010 of the United Kingdom, or any other applicable anti-bribery or anti-corruption laws; or (iv) made, offered, agreed, requested or taken an act in furtherance of any unlawful bribe or other unlawful benefit, including, without limitation, any rebate, payoff, influence payment, kickback or other unlawful or improper payment or benefit. The Company and its Subsidiaries have instituted, maintain and enforce, and will continue to maintain and enforce policies and procedures designed to promote and ensure compliance with all applicable anti-bribery and anti-corruption laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxviii) The operations of the Company and its Subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements, including those of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the applicable money laundering statutes of all jurisdictions where the Company or any of its Subsidiaries conduct business, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental or regulatory agency (collectively, the "**Money Laundering Laws**") and no action, suit or proceeding by or before any court or governmental or regulatory agency, authority or body or any arbitrator involving the Company or any of its Subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxix) Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate or other person acting on behalf of the Company or any of its Subsidiaries is currently the subject or the target of any sanctions administered by the U.S. government (including, without limitation, the Office of Foreign Assets Control of the U.S. Department of the Treasury ("**OFAC**") 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**"), nor is the Company, or any of its Subsidiaries located, organized or resident in a country or territory that is, or was at the time, the subject or the target of comprehensive Sanctions, including, as of the date of this Agreement and without limitation, the Crimea Region of Ukraine, the so-called Donetsk People's Republic, the so-called Luhansk People's Republic, Cuba, Iran and North Korea (each, a "**Sanctioned Country**"). The Company will not directly, or indirectly, use the proceeds of the Offering, or lend, contribute or otherwise make available such proceeds to any Subsidiary, joint venture partner or other person or entity, (i) to fund or facilitate any activities of or business with any person that, at the time of such funding or facilitation, is the subject or the target of Sanctions unless authorized by OFAC or otherwise excepted from Sanctions, (ii) to fund or facilitate any activities of or business in any Sanctioned Country unless authorized by OFAC or otherwise excepted from Sanctions or (iii) in any other manner that will result in a violation by any person (including any person participating in the transaction, whether as underwriter, advisor, investor or otherwise) of applicable Sanctions. Since April 24, 2019, the Company and its Subsidiaries have not knowingly engaged in, are not now knowingly engaged in, and will not knowingly engage in any dealings or transactions unless authorized by OFAC or otherwise excepted from Sanctions (i) with any person that, at the time of the dealing or transaction, is or was the subject or the target of Sanctions or (ii) with, or was at the time of the dealing or transaction, a Sanctioned Country.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxx) The Company and its Subsidiaries maintain a system of "internal control over financial reporting" (as such term is defined in Rule 13(a)-15(f) and 15(d)-15(f) under the 1934 Act) that complies with the requirements of the 1934 Act and has been designed by the Company's principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. The Company's internal control over financial reporting is effective to provide reasonable assurance that: (A) transactions are executed in accordance with management's general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of their financial statements in conformity with GAAP and to maintain accountability for assets; (C) access to assets is permitted only in accordance with management's general or specific authorization; and (D) the recorded accountability for their assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company's auditors and the audit committee of the board of directors of the Company have been advised of: (X) any significant deficiencies in the design or operation of internal controls which could adversely affect the Company's ability to record, process, summarize, and report financial data; and (Y) any fraud, whether or not material, that involves management or other employees who have a role in the Company's internal controls. Since the date of the latest audited financial statements included or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, there has been no change in the Company's internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxi) The Company has established and maintains "disclosure controls and procedures" (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the 1934 Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company and its Subsidiaries is made known to the Company's principal executive officer and principal financial officer by others within the Company or any of its Subsidiaries; and such disclosure controls and procedures are effective at the reasonable assurance level to perform the functions for which they were established subject to the limitations of any such control system.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxii) Neither the Company nor any of its affiliates (as defined in Rule 501(b) of Regulation D under the 1933 Act) has, directly or through any person acting on its or their behalf (other than any Underwriter, as to which no representation is made), taken, directly or indirectly, any action designed to, or that might reasonably be expected to, cause or result in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxiii) Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Company as described in each of the Pre-Pricing Prospectus and the Prospectus will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxiv) No forward-looking statement (within the meaning of Section 27A of the 1933 Act and Section 21E of the 1934 Act) contained in any of the General Disclosure Package or the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxv) Except as described in the section entitled "Underwriting" in the Pre-Pricing Prospectus and the Prospectus, there are no contracts, agreements or understandings between the Company or any of its Subsidiaries and any other person other than the Underwriters pursuant to this Agreement that would give rise to a valid claim against the Company, any Subsidiary or any of the Underwriters for a brokerage commission, finder's fee or like payment in connection with the issuance, purchase and sale of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxvi) There is and has been no failure on the part of the Company and any of the Company's directors or officers, in their capacities as such, to comply in all material respects with any provision of the Sarbanes Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the "**Sarbanes Oxley Act**"), including Section 402 related to loans and Sections 302 and 906 related to certifications.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxvii) The Company and its Subsidiaries (i) maintain, or are entitled to the benefits of, insurance covering their properties, operations, personnel and businesses against such losses and risks as are reasonably adequate to protect them and their businesses in a manner consistent with other businesses similarly situated, or (ii) self-insure against certain of those risks as market conditions require. Neither the Company nor any of its Subsidiaries has received notice from any insurer or agent of such insurer that substantial capital improvements or other expenditures will have to be made in order to continue such insurance, and all material insurance policies are outstanding and duly in force on the date hereof and will be outstanding and duly in force on the Closing Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxviii) Neither the Company nor any of its Subsidiaries has sustained since the date of the latest audited financial statements included in the Registration Statement, the General Disclosure Package and the Prospectus any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, investigation, order or decree, otherwise than as set forth or contemplated in the Registration Statement, the General Disclosure Package and the Prospectus.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xxxix) Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, (i) neither the Company nor any of its Subsidiaries has any lending or similar relationship with any Underwriter or any bank or other lending institution affiliated with any Underwriter; (ii) the Company will not use any of the proceeds from the sale of the Securities by the Company hereunder to reduce or retire the balance of any loan or credit facility extended by any Underwriter or any of its "affiliates" or "associated persons" (as such terms are used in FINRA Rule 5121) or otherwise direct any such proceeds to any Underwriter or any of such "affiliates" or "associated persons"; and (iii) there are and have been no transactions, arrangements or dealings between the Company or any of its Subsidiaries, on one hand, and any Underwriter or any such "affiliates" or "associated persons", on the other hand, that, under FINRA Rule 5110 or 5121, must be disclosed in a submission to FINRA in connection with the offering of the Securities contemplated herein or disclosed in the Registration Statement, the General Disclosure Package or Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xl) The Registration Statement is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the 1933 Act, and the Company is not the subject of a pending proceeding under Section 8A of the 1933 Act. The Company has provided the Representatives with true, complete and correct copies of any written comments received from the Commission by the Company or its legal counsel or accountants, and of any transcripts made by the Company, its legal counsel or accountants of any oral comments received from the Commission, with respect to the Registration Statement, any preliminary prospectus, the Prospectus, any Issuer Free Writing Prospectus or any document incorporated or deemed to be incorporated by reference therein or any amendments or supplements to any of the foregoing and of all written responses thereto (in each case other than comment letters or written responses that are publicly available on EDGAR), and no such comments remain unresolved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xli) Without limitation to the provisions of Section 14 hereof, the Company has not distributed and will not distribute, directly or indirectly (other than through the Underwriters), any "written communication" (as defined Rule 405 under the 1933 Act) or other offering materials in connection with the offering or sale of the Securities, other than the Pre-Pricing Prospectus, the Prospectus, any amendment or supplements to any of the foregoing that are filed with the Commission and any Permitted Free Writing Prospectuses (as defined in Section 14).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xlii) (i) (x) To the knowledge of the Company, there has been no security breach or other compromise of any of the Company's or its Subsidiaries' information technology and, computer systems, networks, hardware, software, sensitive data and databases (including the personally identifiable or confidential data of their respective customers, employees, suppliers, vendors and any third party data maintained by or on behalf of them), that are used in their respective businesses (collectively, "**IT Systems and Data**"), and (y) the Company and its Subsidiaries have not been notified of, and have no knowledge of any event or condition that would reasonably be expected to result in, any security breach or other compromise to their IT Systems and Data, except as would not, in the case of this clause (i), individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; (ii) to the knowledge of the Company, the Company and its Subsidiaries are presently in compliance with all applicable laws or statutes and all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, internal policies and contractual obligations relating to the privacy and security of IT Systems and Data and to the protection of such IT Systems and Data from unauthorized use, access, misappropriation or modification, except as would not, in the case of this clause (ii), individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and (iii) the Company and its Subsidiaries have implemented commercially reasonable backup and disaster recovery plans and procedures.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xliii) Neither the Company nor any of its subsidiaries is a "covered foreign person," as that term is defined in 31 C.F.R. § 850.209. The transactions contemplated in this Agreement will not result in the establishment of a covered foreign person or the engagement by a "person of a country of concern," as defined in 31 C.F.R. § 850.221, in a covered activity, as that term is defined in 31 C.F.R. § 850.208. Neither the Company nor any of its subsidiaries currently engages, or has plans to engage, directly or indirectly, in a covered activity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each certificate signed by any officer of the Company and delivered to the Underwriters or counsel for the Underwriters pursuant to, or in connection with, this Agreement shall be deemed to be a representation and warranty by the Company to the Underwriters as to the matters covered by such certificate.

The Company acknowledges that the Underwriters and, for purposes of the opinions to be delivered to the Underwriters pursuant to Section 8 of this Agreement, counsel to the Company and counsel to the Underwriters will rely upon the accuracy and truth of the foregoing representations and the Company hereby consents to such reliance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. <u>Indemnification</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company agrees to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, the affiliates (for purposes of this Section 6 and Section 7, below, as such term is defined in Rule 405 under the 1933 Act), agents, employees, officers and directors of each Underwriter and the affiliates, agents, employees, officers and directors of any such controlling person from and against any and all losses, liabilities, claims, damages and expenses whatsoever (including, but not limited, to reasonable attorneys' fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all reasonable amounts paid in settlement of any claim or litigation) (collectively, "**Losses**") to which they or any of them may become subject under the 1933 Act, the 1934 Act or otherwise insofar as such Losses (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, or (ii) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any Issuer Free Writing Prospectus (including, but not limited to, any electronic roadshow), the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; *provided* that the Company will not be liable in any such case to the extent, but only to the extent, that any such Loss arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission relating to an Underwriter made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representatives expressly for use in the Pre-Pricing Prospectus or the Prospectus. This indemnity agreement will be in addition to any liability that the Company may otherwise have, including, but not limited to, liability under this Agreement.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, the agents, employees, officers and directors of the Company and of any such controlling person from and against any and all Losses to which they or any of them may become subject under the 1933 Act, the 1934 Act or otherwise insofar as such Losses (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, or (ii) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the General Disclosure Package or the Prospectus, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such Loss arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission relating to such Underwriter made therein in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such Underwriter through the Representatives expressly for use in the Pre-Pricing Prospectus or the Prospectus. The Company and the Underwriters acknowledge that the information described in Section 9 is the only information furnished in writing by the Underwriters to the Company expressly for use in the Pre-Pricing Prospectus or the Prospectus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Promptly after receipt by an indemnified party under subsection 6(a) or 6(b) above of notice of the commencement of any action, suit or proceeding (collectively, an "**action**"), such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement of such action (but the failure so to notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have under this Section 6 except to the extent that it has been prejudiced in any material respect by such failure). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement of such action, the indemnifying party will be entitled to participate in such action, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense of such action with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such action, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to take charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) the named parties to such action (including any impleaded parties) include such indemnified party and the indemnifying parties (or such indemnifying parties have assumed the defense of such action), and such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them that are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such reasonable fees and expenses of counsel shall be borne by the indemnifying parties. In no event shall the indemnifying parties be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for all indemnified parties in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances. An indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent, which consent may not be unreasonably withheld. 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 (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. <u>Contribution</u>*.* In order to provide for contribution in circumstances in which the indemnification provided for in Section 6 of this Agreement is for any reason held to be unavailable from the indemnifying party, or is insufficient to hold harmless a party indemnified under Section 6 of this Agreement, each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such aggregate Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities or (ii) if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as (x) the total proceeds from the offering of Securities (net of discounts and commissions but before deducting expenses) received by the Company are to (y) the total discount and commissions received by the Underwriters. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to above. Notwithstanding the provisions of this Section 7, (i) in no case shall any Underwriter be required to contribute any amount in excess of the amount by which the total discount and commissions applicable to the Securities purchased by such Underwriter pursuant to this Agreement exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act and each director, officer, employee, affiliate and agent of any Underwriter shall have the same rights to contribution as the Underwriters, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act and each director, officer, employee and agent of the Company shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made against another party or parties under this Section 7, notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 7 or otherwise, except to the extent that it has been prejudiced in any material respect by such failure; *provided*, *however*, that no additional notice shall be required with respect to any action for which notice has been given under Section 6 for purposes of indemnification. Anything in this section to the contrary notwithstanding, no party shall be liable for contribution with respect to any action or claim settled without its written consent; *provided*, *however*, that such written consent was not unreasonably withheld. The contribution obligations of the Underwriters under this Section 7 are several in proportion to their respective purchase obligations with respect to the Securities and not joint.

WHEREAS, the Company has duly authorized and desires to cause to be issued pursuant to the Indenture, one new series of Securities to be designated as the "5.500% Senior Notes due 2032" (the "Notes"), having terms as set forth in this Fourth Supplemental Indenture; and

WHEREAS, the Company desires to cause the issuance of the Notes pursuant to Sections 3.01 and 3.03 of the Base Indenture, which sections permit the execution of indentures supplemental thereto to establish the form and terms of Securities; and

WHEREAS, the Company has requested that the Trustee join in the execution of this Fourth Supplemental Indenture to establish the form and terms of the Notes; and

WHEREAS, all things necessary have been done to make the Notes, when issued and executed by the Company and authenticated and delivered under the Indenture, the valid obligations of the Company, and to make this Fourth Supplemental Indenture a valid agreement of the Company, enforceable in accordance with the terms hereof;

NOW, THEREFORE, the Company and the Trustee hereby agree that the following provisions shall amend and supplement the Base Indenture, but only in relation to the Notes to the extent specified herein, and not to any other series of Securities that are or may be outstanding under the Base Indenture:

Article I

<u>Exhibit</u> <u>A</u> is hereby incorporated into this Fourth Supplemental Indenture. The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Fourth Supplemental Indenture, and to the extent applicable, the Company and the Trustee, by their execution and delivery of this Fourth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Fourth Supplemental Indenture, the provisions of this Fourth Supplemental Indenture shall govern and be controlling.

The Notes shall be issued upon original issuance in whole in the form of one or more global Securities ("Global Notes") as provided in the Base Indenture. Each Global Note shall represent such aggregate principal amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of Outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the aggregate principal amount, or any increase or decrease in the aggregate principal amount, of Outstanding Notes represented thereby shall be made by the Trustee in accordance with written instructions, or such other form of instructions as is customary for the Depository, from the Depository or its nominee on behalf of any Person having a beneficial interest in the Global Note. The Company initially appoints The Depository Trust Company to act as Depository with respect to the Global Notes.

A Global Note may not be transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or to another nominee of the Depository, or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. All Global Notes will be exchanged by the Company for Definitive Notes if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the Company delivers to the Trustee notice from the Depository that it is unwilling or unable to continue to act as Depository or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depository is not appointed by the Company within 90 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the Company, at its option but subject to the Depository's rules, determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) there has occurred and is continuing a Default or Event of Default with respect to the Notes, and the Depository notifies the Trustee of its decision to exchange the Global Notes for Definitive Notes.

------

Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depository shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 3.04 and 3.06 of the Base Indenture. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 1.1 or Sections 3.04 or 3.06 of the Base Indenture, shall upon receipt by Trustee of a Company Order, be authenticated and delivered in the form of, and shall be, a Global Note or a Definitive Note, as applicable.

The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depository, in accordance with the provisions of this Fourth Supplemental Indenture and the Applicable Procedures.

Section 1.2 *Title, Amount, Stated Maturity and Interest*.

There are hereby established one new series of Securities to be issued under the Indenture, which are designated as the "5.500% Senior Notes due 2032".

The Trustee shall initially authenticate and deliver for original issue on the date hereof Notes in an initial aggregate principal amount of $500,000,000, upon delivery to the Trustee of a Company Order for the authentication and delivery of such Notes.

The aggregate principal amount of the Notes that may be authenticated and delivered pursuant to the Indenture is unlimited. The aggregate principal amount of the Notes to be issued under the Indenture may be increased at any time, and the Notes may be reopened for issuances of additional Notes, upon a Company Order, without the consent of any Holder and without any further supplement or amendment to the Indenture; *provided* that if such additional Notes are not fungible with the Notes issued on the date of this Fourth Supplemental Indenture for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP number. Each such Company Order for the issuance of additional Notes shall specify the principal amount of the Notes to be authenticated, the date on which the additional Notes are to be authenticated, and the name or names of the initial Holder or Holders thereof. The Notes issued on the date of this Fourth Supplemental Indenture and any additional Notes that may be issued after such date shall be part of the same series of Securities for all purposes under the Indenture.

The Stated Maturity of the Notes shall be September 1, 2032.

The rate at which the Notes shall bear interest, the date from which such interest shall accrue, the dates on which interest shall be payable and the Regular Record Date for interest payable on any Interest Payment Date, in each case, shall be as set forth in the form of the Notes attached as <u>Exhibit</u> <u>A</u> to this Fourth Supplemental Indenture. All payments of principal of, premium, if any, and interest due on any Notes represented by Global Notes on any Interest Payment Date or at Maturity, will be made available to the Trustee by 11:00 a.m., New York City time, on such date, unless such date falls on a day that is not a Business Day, in which case such payments will be made available to the Trustee by 11:00 a.m., New York City time, on the next Business Day. As soon as practicable thereafter, the Trustee will make such payments to the Depository.

Section 1.3 *Security Registrar and Paying Agent*.

The Company initially appoints the Trustee as Security Registrar and Paying Agent with respect to the Notes. The office or agency where Notes may be presented for registration of transfer or exchange and the Place of Payment for the Notes shall initially be the Corporate Trust Office of the Trustee.

Article II

<u>CERTAIN COVENANTS</u> 

Section 2.1 *Offer to Purchase the Notes upon a Change of Control*.

In addition to the foregoing covenants and the other covenants in the Base Indenture, the following covenant shall apply with respect to the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) If a Change of Control Triggering Event occurs with respect to the Notes, each Holder of the Notes will have the right, except as provided below in this Section 2.1, to require the Company to purchase all or any part (in a principal amount of $2,000 or equal to integral multiples of $1,000 in excess thereof) of such Holder's Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Within 30 days following any Change of Control Triggering Event with respect to the Notes, the Company will send a notice (the "Change of Control Offer") to each Holder of Notes, with a copy to the Trustee, stating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) that a Change of Control Triggering Event has occurred with respect to such Notes and that such Holder has the right to require the Company to purchase such Holder's Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant Interest Payment Date) (the "Change of Control Payment");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is sent) (the "Change of Control Payment Date");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) that any Note not properly tendered will remain outstanding and continue to accrue interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) that unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) that Holders electing to have any such Notes in certificated form purchased pursuant to a Change of Control Offer will be required to surrender such Notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of such Notes completed, to the paying agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) that Holders will be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes, *provided* that the paying agent receives, not later than the close of business on the third Business Day preceding the Change of Control Payment Date, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) that if the Company is purchasing a portion of the Note of any Holder, the Holder will be issued a new Note equal in principal amount to the unpurchased portion of the Note surrendered, *provided* that the unpurchased portion of the Note must be equal to a minimum principal amount of $2,000 and an integral multiple of $1,000 in excess of $2,000; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) the procedures determined by the Company, consistent with the Indenture, that a Holder must follow in order to have its Notes repurchased.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) On the Change of Control Payment Date, the Company will, to the extent lawful:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) accept for payment all Notes or portions of Notes (in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer and not properly withdrawn;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes accepted for payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) The Paying Agent will promptly mail or deliver to each Holder of Notes accepted for payment the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Note surrendered, if any; *provided* that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) Notwithstanding the foregoing, the Company is not required to make a Change of Control Offer upon a Change of Control Triggering Event with respect to the Notes if (a) a third party makes the Change of Control Offer with respect to the Notes in the manner, at the times and otherwise in compliance with this Section 2.1 applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not properly withdrawn under such Change of Control Offer, (b) notice of redemption of all of the Outstanding Notes has been given pursuant to Article III hereof, unless and until there is a default in payment of the Redemption Price or (c) in connection with or in contemplation of any Change of Control, the Company has made an offer to purchase (an "Alternate Offer") any and all Outstanding Notes validly tendered at a cash price equal to or higher than the Change of Control Payment and has purchased all Outstanding Notes properly tendered and not withdrawn in accordance with the

------

terms of such Alternate Offer. A Change of Control Offer may be made in advance of a Change of Control Triggering Event, and conditioned upon the occurrence of a Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and any other securities laws or regulations in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with provisions of this Section 2.1, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 2.1 by virtue of its compliance with such securities laws or regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) If Holders of not less than 90% in aggregate principal amount of the Outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer or an Alternate Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all Notes validly tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 10 nor more than 60 days' prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or Alternate Offer described above, to redeem all Notes that remain Outstanding following such purchase at a Redemption Price in cash equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, to the Redemption Date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date). Any redemption pursuant to this paragraph shall be made in compliance with Article III hereof.

Article III

In addition, the Notes may be redeemed as provided in clause (7) of Section 2.1 hereof.

Article V

<u>MISCELLANEOUS PROVISIONS</u> 

Section 5.1 *Definitions*.

All capitalized terms used herein and not otherwise defined below shall have the meanings ascribed thereto in the Base Indenture. The following are additional definitions used in this Fourth Supplemental Indenture:

"Applicable Procedures" means, with respect to any transfer or exchange of or for beneficial interests in any Global Note, the rules and procedures of the Depository, Euroclear and Clearstream that apply to such transfer or exchange.

"Beneficial Owner" has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular "person" (as that term is used in Section 13(d)(3) of the Exchange Act), such "person" will be deemed to have beneficial ownership of all securities that such "person" has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms "Beneficially Owns" and "Beneficially Owned" have a corresponding meaning. For purposes of this definition, a Person shall not be deemed to Beneficially Own securities that are the subject of a stock purchase agreement, merger agreement or similar agreement until consummation of the transactions or, as applicable, series of related transactions contemplated thereby.

"Change of Control" means:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) any transaction as a result of which any "person" or "group" of related persons (as such terms are used in Sections 13(d) and 14(d) of the Exchange Act), becomes the Beneficial Owner, directly or indirectly, of more than 50% of the total voting power of the Voting Stock of the Company (for the purposes of this clause (1), such person or group shall be deemed to Beneficially Own any Voting Stock of the Company held by a parent entity, if such person or group Beneficially Owns, directly or indirectly, more than 50% of the total voting power of the Voting Stock of such parent entity);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole to any "person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the adoption by the shareholders of the Company of a plan or proposal for the liquidation or dissolution of the Company.

------

Notwithstanding the preceding, a Change of Control shall not be deemed to occur upon the consummation of any actions undertaken by the Company solely for the purpose of changing the Company's legal structure. In addition, notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control under clause (1) above if (i) the Company becomes a direct or indirect wholly owned Subsidiary of a holding company and (ii) (A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company's Voting Stock immediately prior to that transaction, or (B) (1) immediately following that transaction, the holders of the Company's Voting Stock immediately prior to that transaction are the Beneficial Owners, directly or indirectly, of more than 50% of the Voting Stock of such holding company and (2) immediately following that transaction, no Person becomes the Beneficial Owner of Voting Stock representing 50% or more of the voting power of the total outstanding Voting Stock of such holding company.

"Change of Control Triggering Event" means, with respect to the Notes, the occurrence of both a Change of Control and a Rating Decline with respect to such Notes.

"Definitive Notes" means a certificated Note registered in the name of the Holder thereof.

"Global Note" means, each of the Notes deposited with or on behalf of and registered in the name of the Depository or its nominee, substantially in the form of <u>Exhibit A</u> hereto and that bears the Global Note legend and that has the "Schedule of Increases or Decreases in Global Note" attached thereto, issued in accordance with Section 2.01 of the Base Indenture.

"Initial Notes" means, the Notes issued on the date of this Fourth Supplemental Indenture.

"Investment Grade Rating" means a rating of "Baa3" or higher by Moody's or "BBB-" or higher by S&P, or the equivalent by any successor Rating Agency.

"Moody's" means Moody's Investors Service, Inc. or any successor to the rating agency business thereof.

"Notes" has the meaning set forth in the recitals hereto. The Initial Notes and any additional Notes issued in accordance with Section 1.1 hereof shall be treated as a single series for all purposes under the Indenture, and unless the context otherwise requires, all references to the Notes shall include the Initial Notes and any additional Notes.

"Participant" means, with respect to the Depository, Euroclear or Clearstream, a Person who has an account with the Depository, Euroclear or Clearstream, respectively (and, with respect to DTC, shall include Euroclear and Clearstream).

"Rating Agency" means each of S&P and Moody's, or if S&P or Moody's or both shall not make a rating on the Notes, publicly available, a nationally recognized statistical rating agency or agencies, as the case may be, shall be selected by the Company and substituted for S&P or Moody's, or both, as the case may be.

------

"Rating Decline" shall be deemed to have occurred in relation to the Notes if, 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 30-day period following public notice of the occurrence of the Change of Control (which period shall be extended so long as the rating of such Notes is under publicly announced consideration for possible downgrade by either of the Rating Agencies and the other Rating Agency has either downgraded, or publicly announced that it is considering downgrading, such Notes), each of the Rating Agencies decreases its rating of the Notes by one or more gradations (including gradations within categories as well as between rating categories) to a rating that is below its rating of the Notes on the day immediately prior to the earlier of (i) the date of the first public announcement of the possibility of a proposed transaction that would result in a Change of Control or (ii) the date that the possibility of such transaction is disclosed to either of the Rating Agencies. Notwithstanding the foregoing, if the Notes have an Investment Grade Rating by each of the Rating Agencies on the day immediately prior to the earlier of (i) the date of the first public announcement of the possibility of a proposed transaction that would result in a Change of Control or (ii) the date that the possibility of such transaction is disclosed to either of the Ratings Agencies, then "Rating Decline" means a decrease in the ratings of the Notes by one or more gradations (including gradations within categories as well as between rating categories) by each of the Rating Agencies such that the rating of the Notes by each of the Rating Agencies falls below an Investment Grade Rating no later than 30 days following public notice of the occurrence of the Change of Control (which 30-day period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by either of the Rating Agencies and the other Rating Agency has either downgraded, or publicly announced that it is considering downgrading, the Notes).

"S&P" means S&P Global Ratings, a division of S&P Global Inc., or any successor to the rating agency business thereof.

[REVERSE OF NOTE]

**HF SINCLAIR CORPORATION** 

**5.500% SENIOR NOTE DUE 2032** 

This Note is one of a duly authorized issue of debentures, notes or other evidences of indebtedness of HF SINCLAIR CORPORATION, a Delaware corporation (the "Company"), issued under the Indenture hereinafter referred to and is one of a series of such debentures, notes or other evidences of indebtedness designated pursuant thereto as 5.500% Senior Notes due 2032 (herein, the "Notes") of the Company.

1. *Interest.*

The Company promises to pay interest on the principal amount of this Note at the rate of 5.500% per annum. The Company will pay interest semiannually in arrears on March 1 and September 1 of each year, beginning [ ⚫ ] (each an "Interest Payment Date"), and on the Maturity of the Notes, or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Notes will accrue from the most recent Interest Payment Date on which interest has been paid [or, with respect to Notes issued on the date of the Fourth Supplemental Indenture, from August 18, 2025]; *provided*, that if there is no existing Default in the payment of, or provisions for, interest, and if this Note is authenticated between a Regular Record Date referred to on the face hereof (whether or not a Business Day) and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. The interest so payable, and punctually paid or provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest as set forth on the face hereof; provided, however, that interest payable at Maturity of this Note will be payable to the Person to whom the principal hereof shall be payable. Any such interest which is so payable, but is not punctually paid or duly provided for on any Interest Payment Date, shall forthwith cease to be payable to the Holder on such Regular Record Date, and may be paid as more fully provided in the Indenture. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The Corporate Trust Office is currently located at Computershare Trust Company, N.A., Corporate Trust Services, 1505 Energy Park Drive, St. Paul, MN 55108.

4. *Indenture.*

Reference is made hereby to (i) the Indenture, dated as of April 27, 2022 (the "Base Indenture"), between the Company as issuer and Computershare Trust Company, N.A., as trustee (the "Trustee") and (ii) the Fourth Supplemental Indenture thereto, dated as of August 18, 2025 (the "Fourth Supplemental Indenture"), between the Company and the Trustee, providing for the issuance of the Notes and certain other series of Securities. The Base Indenture, as amended and supplemented by the Fourth Supplemental Indenture, and as may be further duly amended and supplemented in accordance with the terms thereof, is referred to herein as the "Indenture." The terms of the Notes include those stated in the Indenture (including terms defined therein, which terms when used but not defined herein, unless the context requires otherwise, shall have the meanings assigned to such terms in the Indenture) and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "TIA"), as in effect on the date of execution of the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms.

The Notes are unsecured general obligations of the Company initially limited to $500,000,000 in aggregate principal amount; provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount as provided in the Indenture. The Indenture provides for the issuance of other series of debentures, notes and other evidences of indebtedness (including the Notes, the "Securities") thereunder.

5. *Denominations; Transfer; Exchange.*

The Notes are to be issued in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange, Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges and fees required by law or permitted by the Indenture. The Company hereby irrevocably undertakes to the Holder hereof to exchange this Note in accordance with the terms of the Indenture without service charge.

------

6. *Person Deemed Owner.*

The registered Holder of a Note may be treated as the owner of such Note for all purposes.

7. *Optional Redemption.*

The Notes are redeemable, in whole or in part, at the option of the Company at any time or from time to time prior to maturity, as provided below or as provided in Section 2.1 of the Fourth Supplemental Indenture.

Prior to July 1, 2032 (the "Par Call Date"), the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, less (b) interest accrued to the Redemption Date, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) 100% of the principal amount of the Notes to be redeemed,

plus, in each case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date. In each case, the redemption is subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or before the Redemption Date.

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

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("H.15") under the caption "U.S. government securities–Treasury constant maturities–Nominal" (or any successor caption or heading) ("H.15 TCM"). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the "Remaining Life"); or (2) if there is no such Treasury constant maturity

------

on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places. The Company will, prior to the Redemption Date, file with the trustee an Officers' Certificate setting forth the Treasury Rate. The Trustee shall have no duty to verify the Company's calculation of the Treasury Rate.

Any such redemption may, at the discretion of the Company, be conditioned upon the closing of another transaction, including a sale of securities or other financing, in each case as specified in the notice in reasonable detail. A notice of conditional redemption will be of no effect unless all conditions to the redemption have occurred on or before the Redemption Date or have been waived by the Company on or before the Redemption Date. The Company will provide notice of the satisfaction of all conditions as soon as practicable following occurrence of the conditions. The Company will provide written notice of a delay or rescission of such notice of redemption (and rescission and cancellation of the redemption of the Notes) to the Trustee no later than 10:00 a.m., New York City time, on the Redemption Date. Upon receipt of such notice of delay of such Redemption Date or rescission of such notice of redemption, such Redemption Date shall be automatically delayed or such notice of redemption shall be automatically rescinded, as applicable, and the redemption of the Notes shall be automatically delayed or rescinded and cancelled, as applicable, as provided in such notice.

------

The Company will mail or deliver a notice of redemption at least 10 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select the Notes to be redeemed in accordance with the provisions of Section 12.03 of the Base Indenture.

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

8. *Change of Control Trigger Event.* 

If a Change of Control Triggering Event occurs, the Company may be obligated to offer to purchase all outstanding Notes as provided in the Indenture.

9. *Amendment; Supplement; Waiver.*

Subject to certain exceptions and limitations set forth in the Indenture, the Indenture may be supplemented with the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of each series affected by such supplemental indenture, and any past default under the Indenture with respect to the Notes, and its consequences, may be waived by the Holders of not less than a majority in aggregate principal amount of the Outstanding Notes in accordance with the terms of the Indenture. Without the consent of any Holder, the Company and the Trustee may supplement the Indenture for certain purposes, as provided in the Indenture.

A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of Securities under the Indenture, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Securities of any other series.

10. *Defaults and Remedies.*

If any Event of Default with respect to the Notes at any time outstanding occurs and is continuing (other than an Event of Default with respect to certain events of bankruptcy, insolvency or reorganization in respect of the Company as specified in the Indenture), either the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal amount of, and accrued and unpaid interest, if any, on, all of the Notes to be due and payable immediately. If an Event of Default relating to such events of bankruptcy, insolvency or reorganization occurs, such amount shall ipso facto become immediately due and payable. At any time after a declaration or occurrence of acceleration with respect to the Notes has been made, but before a judgment or decree based on such acceleration has been obtained, the Event of Default giving rise to such declaration of acceleration shall, under certain circumstances, be deemed to have been waived, and such declaration and its consequences shall be deemed to have been rescinded and annulled.

------

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of other Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether not any such direction unduly prejudices the rights of such Holders) or involves the Trustee in personal liability; *provided, however,* that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium (if any) or interest) if in good faith it determines that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee.

11. *Discharge Prior to Maturity.*

The Indenture shall be satisfied and discharged and the Notes canceled upon the payment of all Notes and, as provided in Article 4 of the Base Indenture, shall be satisfied and discharged except for certain obligations upon the irrevocable deposit with the Trustee of funds sufficient for such payment.

12. *Trustee Dealings with Company.*

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates or any subsidiary of the Company's Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not the Trustee.

13. *Authentication.*

This Note shall not be valid until authenticated by the manual signature of an authorized signer of the Trustee.

14. *CUSIP Numbers.*

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the correctness of such numbers as printed on the Notes and reliance may be placed only on the other identification numbers printed thereon.

| Re: | 5.500% Notes due 2032  |

---

Dear Ladies and Gentlemen:

We have acted as counsel for HF Sinclair Corporation, a Delaware corporation (the "<u>Corporation</u>"), with respect to certain legal matters in connection with the registration by the Corporation under the Securities Act of 1933 (the "<u>Securities Act</u>") of the offer and sale by the Corporation of $500,000,000 aggregate principal amount of 5.500% Senior Notes due 2032 (the "<u>Notes</u>"), pursuant to the Underwriting Agreement, dated August 11, 2025 (the "<u>Underwriting Agreement</u>"), among the Corporation and Citigroup Global Markets Inc., TD Securities (USA) LLC, Truist Securities, Inc. and Scotia Capital (USA) Inc., for themselves and as representatives of the underwriters party thereto (the "<u>Underwriters</u>").

The Notes have been offered for sale pursuant to a prospectus supplement, dated August 11, 2025 filed with the Securities and Exchange Commission (the "<u>SEC</u>") pursuant to Rule 424(b) on August 13, 2025, to the prospectus, dated February 26, 2025 (as amended and supplemented by the prospectus supplement, the "<u>Prospectus</u>"), that constitutes a part of the Corporation's Registration Statement on Form S-3 (Registration No. 333-285291), filed with the SEC on February 26, 2025 (the "<u>Registration Statement</u>"), which Registration Statement became effective upon filing. The Notes will be issued under an indenture, dated as of April 27, 2022 (the "<u>Base Indenture</u>"), between the Corporation and Computershare Trust Company, N.A., as trustee (the "<u>Trustee</u>"), as supplemented by a fourth supplemental indenture, dated as of August 18, 2025, between the Corporation and the Trustee (the "<u>Fourth Supplemental Indenture</u>," and, together with the Base Indenture, the "<u>Indenture</u>").

We have reviewed originals or copies, certified or otherwise identified to our satisfaction, of (i) the Amended and Restated Certificate of Incorporation and the Amended and Restated By-Laws of the Corporation, (ii) certain resolutions adopted by the Board of Directors of the Corporation, (iii) certain resolutions adopted by the Pricing Committee of the Board of Directors of the Corporation, (iv) the Registration Statement, (v) the Prospectus, (vi) the Base Indenture and Fourth Supplemental Indenture and (vii) such other certificates, instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed. In addition, we reviewed such questions of law as we considered appropriate.

As to any facts material to the opinions contained herein, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Corporation.

In connection with rendering the opinions set forth below, we have assumed that (i) all information contained in all documents we reviewed is true, correct and complete, (ii) all signatures on all documents we reviewed are genuine, (iii) all documents submitted to us as originals are true and complete, (iv) all documents submitted to us as copies are true and complete copies of the originals thereof, (v) all persons executing and delivering the documents we reviewed were competent to execute and deliver such documents, (vi) all Notes will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Prospectus and the Registration Statement, (vii) the Underwriting Agreement has been duly authorized and validly executed and delivered by the Underwriters and (viii) the Indenture was duly authorized, executed, and delivered by the Trustee.

Based upon such review and the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that the Notes have been duly authorized, executed and issued by the Corporation and, assuming that the Notes have been duly authenticated by the Trustee, they constitute valid and binding obligations of the Corporation, enforceable against the Corporation in accordance with their terms, except as that enforcement is subject to any applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or conveyance or other laws relating to or affecting creditors' rights generally, and general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law), and are entitled to the benefits of the Base Indenture, as amended and supplemented by the Fourth Supplemental Indenture.

This opinion is limited in all respects to the laws of the State of New York, the General Corporation Law of the State of Delaware and the federal laws of the United States of America, and we do not express any opinion as to the laws of any other jurisdiction.

This opinion letter may be filed as an exhibit to the Registration Statement. We also consent to the reference to this firm under the heading "Legal Matters" in the Prospectus. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the SEC promulgated thereunder.
