14

9. (a) The Company will indemnify and hold harmless each Underwriter, their directors and officers, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or any such director, officer or controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) or any Pricing Disclosure Package under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter, their director, officers and controlling person for any legal or other expenses reasonably incurred by such Underwriter or any director, officer or controlling person in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any Pricing Disclosure Package in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein. The Company and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Company for inclusion in the Pricing Disclosure Package and the Prospectus consists of the names of the Underwriters, the information set forth in the first and second sentence of the third paragraph and the sixth and seventh paragraphs under the caption “Underwriting (Conflicts of Interest)” in the Prospectus.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any Pricing Disclosure Package or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any Pricing Disclosure Package in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the

17

Representatives expressly for use therein; and will reimburse the Company, its directors, officers and controlling persons upon demand for any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any action, proceeding, claim as such expenses are incurred.

(c) Promptly after receipt by any person in respect of which an indemnity may be sought under subsection (a) or (b) above (the “indemnified party”) of notice of the commencement of any action, proceeding or investigation, such indemnified party shall, if a claim in respect thereof is to be made against the person against whom such indemnity may be sought (the “indemnifying party”) under such subsection, notify the indemnifying party in writing of the commencement thereof and provide sufficient information in such notification as to the nature and basis of such indemnified party’s involvement in such action, proceeding or investigation; but the omission to so notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party pursuant to such subsection unless and to the extent it did not otherwise learn of such action. In case any such action, proceeding or investigation shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election to so assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in

18

such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability which the respective Underwriters may otherwise have.

10. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at the Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Shares, or the Company notifies you that it has so arranged for the purchase of such Shares, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus that in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

19

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection 10(a) above, the aggregate number of such Shares which remains unpurchased does not exceed one eleventh of the aggregate number of all the Shares, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection 10(a) above, the aggregate number of Shares which remains unpurchased exceeds one eleventh of the aggregate number of Shares to be purchased at the Time of Delivery, or if the Company shall not exercise the right described in subsection 10(b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, or any of its directors, officers or any person controlling any Underwriter, the Company, or any of its directors, officers or any controlling person of the Company, and shall survive delivery of and payment for the Securities. The provisions of Section 7 and Section 9 hereof shall survive the termination or cancellation of this Agreement.

12. If for any reason any Securities are not delivered by or on behalf of the Company as provided herein other than because of a termination of this Agreement pursuant to Section 10, the Company will reimburse the Underwriters through you for all reasonable out-of-pocket expenses approved in writing by you, including reasonable fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities but the Company shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Securities, except as provided in Sections 7 and 9 hereof.

20

13. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

14. The Company acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

15. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

16. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors, heirs, executors, and administrators, and the directors, officers and controlling persons referred to in Section 9 hereof, and no other person shall have any right or obligation hereunder.

17. In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined below) of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined below) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For the purposes of this provision, (a) the term “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k); (b) the term “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b); (c) the term “Default Right” has the meaning assigned to that term

21

in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable; and (d) the term “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

18. This Agreement will be governed by and construed in accordance with the laws of the State of New York.

19. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any action, claim, suit or legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

EXHIBIT A

Matters to be Addressed in the Opinion of Hope D. Mehlman, Executive Vice President, Corporate Secretary, Chief Governance Officer and Deputy General Counsel for the Company:

EXHIBIT B-1

Matters to be Addressed in the Opinion of Sullivan & Cromwell LLP, Counsel for the Company:

In connection with the several purchases today by you and the other Underwriters named in Schedule I to the Underwriting Agreement, dated June 2, 2020 (the “Underwriting Agreement”), between Regions Financial Corporation, a Delaware corporation (the “Company”), and you, as Representatives of the several Underwriters named therein (the “Underwriters”), of 350,000 depositary shares (the “Depositary Shares”), each representing a 1/100th interest in a share of the Company’s Non-Cumulative Perpetual Preferred Stock, Series D, par value $1 per share and liquidation preference $100,000 per share (the “Preferred Shares” and, together with the Depositary Shares, the “Securities”), which, when issued, will be deposited against delivery of Depositary Receipts (the “Depositary Receipts”) evidencing the Depositary Shares that will be issued pursuant to the Deposit Agreement, dated as of the date hereof (the “Deposit Agreement”), entered into among the Company, Computershare, Inc. and Computershare Trust Company, N.A., jointly as depositary (jointly, the “Depositary”), and the holders from time to time of the Depositary Receipts, we, as counsel for the Company, have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that:

(1) The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Delaware.

(2) The Preferred Shares have been duly authorized and validly issued and are fully paid and nonassessable.

(3) All regulatory consents, authorizations, approvals and filings required to be obtained or made by the Company under the Covered Laws for the issuance of the Securities in accordance with the Deposit Agreement and the sale and delivery of the Securities by the Company to the Underwriters in accordance with the Underwriting Agreement have been obtained or made.

(4) The issuance of the Depositary Shares in accordance with the Deposit Agreement and the sale and delivery of the Depositary Shares by the Company to the Underwriters in accordance with the Underwriting Agreement does not violate any Covered Laws.

(5) The issuance of the Depositary Shares in accordance with the Deposit Agreement and the sale and delivery of the Depositary Shares by the Company to the Underwriters in accordance with the Underwriting Agreement will not (a) violate the Company’s Amended and Restated Certificate of Incorporation or Restated By-laws, in each case as in effect on the date hereof, or (b) result in a default or breach of any of the agreements listed on Annex A hereto.

(6) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(7) The Deposit Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. We express no opinion, however, as to Section 5.7 of the Deposit Agreement.

(8) Upon due issuance by the Depositary of the Depositary Receipts evidencing the Depositary Shares against the deposit of Preferred Shares in accordance with the provisions of the Deposit Agreement and payment therefore in accordance with the Underwriting Agreement, the Depositary Receipts will entitle the persons in whose names the Depositary Receipts are registered to the rights specified therein and in the Deposit Agreement, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(9) The Company is not, and immediately after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Prospectus Supplement dated June 2, 2020, would not be on the date hereof an “investment company” as such term is defined in the Investment Company Act of 1940. In connection with our opinion set forth in paragraph (1) above, we have relied solely on a good standing certificate for the Company issued by the Secretary of State of the State of Delaware and we have assumed that the Company has been duly incorporated.

In connection with our opinion set forth in paragraph (1) above, we have relied solely on a good standing certificate for the Company issued by the Secretary of State of the State of Delaware and we have assumed that the Company has been duly incorporated.

For purposes of the opinions in paragraphs (3) and (4) above, “Covered Laws” means the Federal laws of the United States, the statutory laws of the State of New York and the General Corporation Law of the State of Delaware (including the published rules and regulations thereunder) that in our experience normally are applicable to general business corporations and the issuance, sale and delivery of the Securities; provided, however, that such term does not include Federal or state securities laws, antifraud laws or fraudulent transfer laws, tax laws, the Employee Retirement Income Security Act of 1974, antitrust laws or any law that is applicable to the Company, the Securities or the issuance, sale or delivery thereof solely as part of a regulatory regime applicable to the Company or its affiliates due to its or their status, business or assets.

The foregoing opinion is limited to the Federal laws of the United States, the laws of the State of New York and the General Corporation Law of the State of Delaware, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

We have also relied as to certain matters upon information obtained from public officials, officers of the Company and other sources believed by us to be responsible, and we have assumed that the Preferred Shares have been deposited with the Depositary in accordance with the Deposit Agreement, that the Deposit Agreement has been duly authorized, executed and delivered by the Depositary, that the Depositary Receipts have been duly issued against deposit of the Preferred Shares with the Depositary, that the certificate evidencing the Depositary Receipts conforms to the specimen thereof examined by us, that the Depositary Receipts have been duly executed and delivered by one of the Depositary’s authorized officers and, if necessary, have been duly countersigned by the registrar for the Depositary Receipts, that the Preferred Shares have been duly recorded by a transfer agent and duly registered by a registrar thereof in the direct registration system of the Company, that the notice required by Section 151(f) of the General Corporation Law of the State of Delaware will be given to the holders of the Preferred Shares within a reasonable time following the issuance of the Preferred Shares, and that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

This letter is furnished by us, as counsel to the Company, to you, as Representatives of the Underwriters, solely for the benefit of the Underwriters in their capacity as such, and may not be relied upon by any other person. This letter may not be quoted, referred to or furnished to any purchaser or prospective purchaser of the Securities and may not be used in furtherance of any offer or sale of the Securities.

Annex A

EXHIBIT B-2

Matters to be Addressed in the Disclosure Letter of Sullivan & Cromwell LLP, Counsel for the Company:

This is with reference to the registration under the Securities Act of 1933 (the “Securities Act”) and offering by Regions Financial Corporation (the “Company”) of 350,000 depositary shares (the “Depositary Shares”), each representing a 1/100th interest in a share of Non-Cumulative Perpetual Preferred Stock, Series D, par value $1 per share and liquidation preference $100,000 per share, evidenced by depositary receipts (the “Depositary Receipts”) to be issued pursuant to the Deposit Agreement, dated June 5, 2020 (the “Deposit Agreement”), among the Company, Computershare Inc. and Computershare Trust Company, N.A., jointly as depositary (jointly, the “Depositary”), and the holders from time to time of the Depositary Receipts.

The Registration Statement relating to the Securities (File No. 333-229810) was filed on Form S-3 in accordance with the procedures of the Securities and Exchange Commission (“Commission”) permitting a delayed or continuous offering of securities pursuant thereto and, if appropriate, a post-effective amendment, document incorporated by reference therein or prospectus supplement that provides information relating to the terms of the securities and the manner of their distribution. The Securities have been offered by the Prospectus, dated February 22, 2019 (the “Basic Prospectus”), as supplemented by the Prospectus Supplement, dated June 2, 2020 (the “Prospectus Supplement”), which updates or supplements certain information contained in the Basic Prospectus. The Basic Prospectus, as supplemented by the Prospectus Supplement, does not necessarily contain a current description of the Company’s business and affairs since, pursuant to Form S-3, it incorporates by reference certain documents filed with the Commission that contain information as of various dates.

As counsel to the Company, we reviewed the Registration Statement, the Basic Prospectus, the Prospectus Supplement and the documents listed in Schedule A (those listed documents, taken together with the Basic Prospectus, being referred to herein as the “Pricing Disclosure Package”) and participated in discussions with your representatives and those of the Company and its accountants. Between the date of the Prospectus Supplement and the time of delivery of this letter, we participated in further discussions with your representatives and those of the Company and its accountants, concerning certain matters relating to the Company and reviewed certificates of certain officers of the Company, letters addressed to you from the Company’s accountants and an opinion addressed to you from the Company’s counsel. On the basis of the information that we gained in the course of the performance of the services referred to above, considered in the light of our understanding of the applicable law (including the requirements of Form S-3 and the character of prospectus contemplated thereby) and the experience we have gained through our practice under the Securities Act, we confirm to you that, in our opinion, the Registration Statement, as of the date of the Prospectus Supplement, and the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, appeared on their face to be appropriately responsive, in all material respects relevant to the offering of the Securities, to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Also, we confirm to you that the statements contained in the

Prospectus Supplement under the captions “Description of the Series D Preferred Stock”, “Description of Depositary Shares” and “Description of Capital Stock”, insofar as they relate to provisions of the Company’s amended and restated certificate of incorporation, restated by-laws and certificate of designations therein described, under the caption “Underwriting (Conflicts of Interest)”, insofar as they relate to provisions of the Underwriting Agreement between the Company and the Underwriters therein described, and under the caption “United States Federal Income Tax Consequences” and “Employee Retirement Income Security Act”, insofar as they purport to constitute a summary of matters of U.S. federal income tax law or the U.S. Employee Retirement Income Security Act of 1974, as amended, and regulations or legal conclusions with respect thereto, constitutes a fair and accurate summary of such provisions in all material respects.

Further, nothing that came to our attention in the course of such review has caused us to believe that, insofar as relevant to the offering of the Securities,

(a) the Registration Statement, as of the date of the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading,

(b) the Pricing Disclosure Package, as of 3:45 P.M. on June 2, 2020, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(c) the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the date of the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

We also advise you that nothing that came to our attention in the course of the procedures described in the second sentence of the preceding paragraph has caused us to believe that the Basic Prospectus, as supplemented by the Prospectus Supplement, as of the time of delivery of this letter, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such, however, that we do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, except to the extent specifically noted in the fourth sentence of the second preceding paragraph. Also, we do not express any opinion or belief as to the financial statements or other financial data derived from accounting records contained in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package, or as to management’s report of its assessment of the effectiveness of the Company’s internal control over financial reporting or the auditors’ report as to the Company’s internal control over financial reporting, each as included in the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Pricing Disclosure Package.

This letter is furnished by us, as counsel to the Company, to you, as Representatives of the several Underwriters, solely for the benefit of the Underwriters in their capacity as such, and may not be relied upon by any other person. This letter may not be quoted, referred to or furnished to any purchaser or prospective purchaser of the Securities and may not be used in furtherance of any offer or sale of the Securities.
