1933 Act or the 1934 Act, the Company and the Guarantor forthwith will (i) notify the Underwriters to suspend solicitation of purchases of the Securities and (ii) at its expense, make any such filing or prepare and furnish to the Underwriters a reasonable number of copies of a supplement or supplements or an amendment or amendments to the Final Supplemented Prospectus which will supplement or amend the Final Supplemented Prospectus so that, as supplemented or amended, it will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances when the Final Supplemented Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the ▇▇▇▇ ▇▇▇) is delivered, not misleading or which will effect any other necessary compliance. In case any Underwriter is required to deliver a prospectus in connection with the sale of any Securities after the expiration of the period specified in the preceding sentence, the Company or the Guarantor, upon the request of such Underwriter, will furnish to such Underwriter, at the expense of such Underwriter, a reasonable quantity of a supplemented or amended prospectus, or supplements or amendments to the Final Supplemented Prospectus, complying with Section 10(a) of the 1933 Act. During the period specified in the second sentence of this subsection, the Company and the Guarantor will continue to prepare and file with the Commission on a timely basis all documents or amendments required under the 1934 Act and the rules and regulations thereunder; provided, that the Company shall not file such documents or amendments without also furnishing copies thereof prior to such filing to the Representatives and Hunton ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP.

(c) The Company and the Guarantor will endeavor, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and the other jurisdictions of the United States as the Representatives may designate; provided, however, that neither the Company nor the Guarantor shall be obligated to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or to file a consent to service of process or to file annual reports or to comply with any other requirements in connection with such qualification deemed by the Company or the Guarantor to be unduly burdensome.

(d) The Company and the Guarantor will make generally available to their security holders as soon as practicable but not later than 45 days after the close of the period covered thereby, an earnings statement of the Guarantor (in form complying with the provisions of Rule 158 of the rules and regulations under the ▇▇▇▇ ▇▇▇) covering a twelve-month period beginning not later than the first day of the Guarantor’s fiscal quarter next following the “effective date” (as defined in Rule 158) of the Registration Statement.

(e) As soon as practicable after the date of this Agreement, and in any event within the time prescribed by Rule 424 under the 1933 Act, the Company and the Guarantor will file the Final Supplemented Prospectus, in a form approved by the Representatives, such approval not to be unreasonably withheld, with the Commission and will advise the Representatives of such filing and will confirm such advice in writing. Furthermore, the Company and the Guarantor will make any other required filings pursuant to Rule 433(d)(1) under the 1933 Act within the time required by such Rule.

(f) During a period of 15 days from the date of this Agreement, neither the Company nor the Guarantor will, without the Representatives’ prior written consent, directly or

indirectly, sell, offer to sell, grant any option for the sale of, or otherwise dispose of, any Senior Notes or any security convertible into or exchangeable into or exercisable for the Senior Notes or any debt securities substantially similar to the Senior Notes (except for the Senior Notes issued pursuant to this Agreement). The Representatives agree that commercial paper or other debt securities with scheduled maturities of less than one year are not subject to this Section 4(f).

respective dates of delivery thereof to the effect that: they are an independent registered public accounting firm with respect to the Guarantor within the meaning of the 1933 Act and the rules and regulations under the 1933 Act; in their opinion, the financial statements of the Guarantor audited by them and incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, comply as to form in all material respects with the applicable accounting requirements of the 1934 Act and the rules and regulations under the 1934 Act; and on the basis of certain limited procedures performed through a specified date not more than three business days prior to the date of such letter, namely (i) reading the minute books of the Guarantor; (ii) performing the procedures specified by the standards of the Public Company Accounting Oversight Board (United States) for a review of interim financial statement information as described in PCAOB AS 4105, “Reviews of Interim Financial Information,” on the unaudited financial statements, if any, of the Guarantor, incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, and on the latest available unaudited financial statements of the Guarantor, if any, for any calendar quarter subsequent to the date of those incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable; and (iii) making inquiries of certain officials of the Guarantor who have responsibility for financial and accounting matters regarding such unaudited financial statements or any specified unaudited amounts derived therefrom (it being understood that the foregoing procedures do not constitute an audit performed in accordance with generally accepted auditing standards and they would not necessarily reveal matters of significance with respect to the comments made in such letter, and accordingly that Deloitte & Touche LLP make no representations as to the sufficiency of such procedures for the Underwriters’ purposes), nothing came to their attention that caused them to believe that: (1) any material modifications should be made to the unaudited condensed financial statements, if any, incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, for them to be in conformity with GAAP; (2) such unaudited condensed financial statements do not comply as to form in all material respects with the applicable accounting requirements of the 1934 Act as it applies to Form 10-Q and the related published rules and regulations thereunder; (3) the audited or unaudited amounts for Operating Revenues, Earnings Before Income Taxes and Net Income set forth in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, do not agree with the amounts set forth in or derived from the audited or unaudited financial statements of the Guarantor for the same period included or incorporated by reference in the Registration Statement; (4) as of a specified date not more than three business days prior to the date of delivery of such letter, there has been any change in the capital stock or long-term debt of the Guarantor or any decrease in net assets of the Guarantor as compared with amounts shown in the latest audited or unaudited balance sheet incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, except in each case for changes or decreases which (i) the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable, disclose have occurred or may occur, (ii) are occasioned by the declaration of dividends, (iii) are occasioned by regularly

scheduled payments of capitalized lease obligations, (iv) are occasioned by the purchase or redemption of bonds or stock to satisfy mandatory or optional redemption provisions relating thereto, (v) are occasioned by the reclassification of current maturities of long-term debt, (vi) are occasioned by the amortization of debt issuance costs or (vii) are disclosed in such letter; and (5) the unaudited amounts for Operating Revenues, Earnings Before Income Taxes and Net Income for any calendar quarter subsequent to those set forth in (3) above, which, if available, shall be set forth in such letter, do not agree with the amounts set forth in or derived from the unaudited financial statements of the Guarantor for the same period or were not determined on a basis substantially consistent with that of the corresponding audited amounts included or incorporated by reference in the Registration Statement and the Pricing Prospectus or the Registration Statement, the Pricing Prospectus and the Final Supplemented Prospectus, as applicable.

(f) On the Closing Date, Hunton ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, counsel for the Underwriters shall have been furnished with such documents and opinions as it may reasonably require for the purpose of enabling it to pass upon the issuance and sale of the Securities as herein contemplated and related proceedings, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company and the Guarantor in connection with the issuance and sale of the Securities as herein contemplated shall be satisfactory in form and substance to the Representatives and Hunton ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP, counsel for the Underwriters.

(g) No amendment or supplement to the Registration Statement or the Final Supplemented Prospectus filed subsequent to the date of this Agreement (including any filing made by the Company pursuant to Section 13 or 14 of the ▇▇▇▇ ▇▇▇) shall be unsatisfactory in form to Hunton ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP or shall contain information (other than with respect to an amendment or supplement relating solely to the activity of any Underwriter) which, in the reasonable judgment of the Representatives, shall materially impair the marketability of the Securities.

(h) The Company and the Guarantor shall have performed their obligations when and as provided under this Agreement.

If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Representatives by notice to the Company and the Guarantor at any time prior to the Closing Date, and such termination shall be without liability of any party to any other party except as provided in Sections 5, 8 and 10(b) hereof.

SECTION 7. CONDITIONS OF THE OBLIGATIONS OF THE COMPANY AND THE GUARANTOR. The obligations of the Company and the Guarantor shall be subject to the conditions set forth in the first sentence of Section 6(a) hereof. In case such conditions shall not have been fulfilled, this Agreement may be terminated by the Company or the Guarantor by mailing or delivering written notice thereof to the Representatives.

SECTION 8. INDEMNIFICATION.

(a) The Company and the Guarantor jointly and severally agree to indemnify and hold harmless each of the Underwriters and each person, if any, who controls any such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the 1933 Act, the 1934 Act or otherwise, and to reimburse any such Underwriter and such controlling person or persons, if any, for any legal or other expenses incurred by them in connection with defending any actions, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Limited Use Free Writing Prospectus, any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus or, if the Company or the Guarantor shall furnish to the Underwriters any amendments or any supplements thereto, or shall make any filings pursuant to Section 13 or 14 of the 1934 Act which are incorporated therein by reference, in a Limited Use Free Writing Prospectus, any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus, or the Final Supplemented Prospectus as so amended or supplemented, or in any free writing prospectus used by the Company or the Guarantor other than a Permitted Free Writing Prospectus, or a Limited Use Free Writing Prospectus, or arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any such untrue statement or alleged untrue statement or omission or alleged omission which was made in such Limited Use Free Writing Prospectus, Registration Statement, Preliminary Prospectus, Base Prospectus, Pricing Prospectus, Permitted Free Writing Prospectus or Final Supplemented Prospectus in reliance upon and in conformity with information furnished in writing to the Company or the Guarantor by any Underwriter through the Representatives for use therein. Each Underwriter agrees, within ten days after the receipt by it of notice of the commencement of any action in respect of which indemnity may be sought by it, or by any person controlling it, from the Company on account of its agreement contained in this Section 8, to notify the Company in writing of the commencement thereof but the omission of such Underwriter so to notify the Company and the Guarantor of any such action shall not release the Company or the Guarantor from any liability which it may have to such Underwriter or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 8. In case any such action shall be brought against an Underwriter or any such person controlling such Underwriter and such Underwriter shall notify the Company and the Guarantor of the commencement thereof as above provided, the Company and the Guarantor shall be entitled to participate in (and, to the extent that it shall wish, including the selection of counsel, to direct) the defense thereof, at its own expense. In case the Company or the Guarantor elects to direct such defense and select such counsel, any Underwriter or controlling person shall have the right to employ its own counsel, but, in any such case, the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person unless the employment of such counsel has been authorized in writing by the Company and the Guarantor in connection with defending such action. 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 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 any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent.

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company and the Guarantor, its directors and such of its officers who have signed the Registration Statement and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act to the same extent and upon the same terms as the indemnity agreement of the Company and the Guarantor set forth in Section 8(a) hereof, but only with respect to alleged untrue statements or omissions made in a Limited Use Free Writing Prospectus, the Registration Statement, the Preliminary Prospectus, the Base Prospectus, the Pricing Prospectus, any Permitted Free Writing Prospectus or the Final Supplemented Prospectus, or such documents as amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company or the Guarantor by any Underwriter through the Representatives for use therein.

SECTION 9. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY. All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the Company and the Guarantor submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by, or on behalf of the Company or the Guarantor and shall survive delivery of the Securities to the Underwriters.

SECTION 10. TERMINATION OF AGREEMENT.

(a) The Representatives may terminate this Agreement, by notice to the Company and the Guarantor, at any time at or prior to the Closing Date if (i) trading in securities on the New York Stock Exchange shall have been generally suspended or there shall have been a material disruption in settlement in securities generally, (ii) minimum or maximum ranges for prices shall have been generally established on the New York Stock Exchange by the Commission or by the New York Stock Exchange, (iii) a general banking moratorium shall have been declared by federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of major hostilities in which the United States is involved, any declaration of war by the United States Congress or any other substantial national or international calamity, crisis or emergency (including, without limitation, acts of terrorism) affecting the United States, in any such case provided for in clauses (i) through (iv) with the result that, in the reasonable judgment of the Representatives, the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement and the Final Supplemented Prospectus shall have been materially impaired.

(b) If this Agreement shall be terminated by the Representatives pursuant to subsection (a) above or because of any failure or refusal on the part of the Company or the Guarantor to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or the Guarantor shall be unable to perform its obligations under this

Agreement, then in any such case, the Company and the Guarantor will reimburse the Underwriters for the reasonable fees and disbursements of Hunton ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP and for the out of pocket expenses (in an amount not exceeding $10,000) reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities and, upon such reimbursement, the Company and the Guarantor shall be absolved from any further liability hereunder, except as provided in Sections 5 and 8 hereof.

SECTION 11. DEFAULT BY AN UNDERWRITER. If an Underwriter shall fail on the Closing Date to purchase the Securities that it is obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the principal amount of Defaulted Securities does not exceed 10% of the Securities, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the principal amount of Defaulted Securities exceeds 10% of the Securities, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives, the Company or the Guarantor shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the Pricing Prospectus or the Final Supplemented Prospectus or in any other documents or arrangements.

(b) 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.

SECTION 17. EXERCISE OF BAIL-IN POWERS.

due January 15, 2031

Ladies and Gentlemen:

We have acted as special Nevada counsel to Southern Company Gas Capital Corporation, a Nevada corporation (the “Company”), in connection with (i) the Company’s issuance of $500,000,000 aggregate principal amount of its Series 2020A 1.750% Senior Notes due January 15, 2031 (the “Notes”) and the related guarantee thereof (the “Guarantee”) by Southern Company Gas (the “Guarantor”) pursuant to an Indenture (the “Indenture”) dated as of February 20, 2001, by and among the Company, as issuer, the Guarantor, as guarantor, and ▇▇▇▇▇ Fargo Bank, National Association (as successor to The Bank of New York Mellon Trust Company, N.A.), as trustee (the “Trustee”); and (ii) the purchase by the Underwriters (as hereinafter defined) of the Notes pursuant to the terms of an Underwriting Agreement dated August 17, 2020 (the “Underwriting Agreement”), among the Company, the Guarantor and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”).

j)	A copy of the Amended and Restated Bylaws of the Company as adopted July 19, 2016 (the “Bylaws”);


k)	A Certificate of Good Standing for the Company issued by the Nevada Secretary of State on August [ ], 2020;

n)	Certificate of [▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇▇], [Corporate Secretary] of the Company, dated as of August 21, 2020 (the “Officer’s Certificate”); and

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

In addition, we have examined, and have relied as to factual matters upon, the documents delivered to you at the closing (except the certificate representing the Notes, of which we have examined a specimen), and we have made such other and further investigations as we deemed necessary to express the opinions hereinafter set forth. In such examination, we have assumed (i) the genuineness of all signatures (ii) the legal capacity of natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.

5. No order, consent or other authorization or approval is required by any governmental authority of the State of Nevada for the issuance by the Company of the Notes, except with respect to applicable state securities or “blue sky” laws, as to which we express no opinion.

6. The execution and delivery by the Company of the Underwriting Agreement, and the Notes do not, and if the Company were now to perform its obligations under the Underwriting Agreement, the Indenture and the Notes such performance would not, result in any: (i) violation of the Company’s Articles of Incorporation or Bylaws; (ii) violation of any existing State of Nevada statute, regulation, rule or law to which the Company is subject; or (iii) violation of any judicial or administrative decree, writ, judgment or order to which, to the knowledge of such counsel, the Company is subject.

The attorneys in this firm that are rendering this opinion are members of the State Bar of Nevada and we do not purport to express any opinion herein concerning any law other than the laws of the State of Nevada.

This opinion letter is rendered by us only to you and is solely for your benefit in your capacity as Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent except that ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP may rely on this opinion in giving its opinion pursuant to the Underwriting Agreement, insofar as such opinion relates to matters of Nevada law and Hunton ▇▇▇▇▇▇▇ ▇▇▇▇▇ LLP may rely on this opinion in giving its opinion pursuant to the Underwriting Agreement, insofar as such opinion relates to matters of Nevada law. This opinion is expressed as of the date hereof, and we do not assume any obligation to update or supplement it to reflect any fact or circumstance that hereafter comes to our attention, or any change in law that hereafter occurs.

3. All orders, consents or other authorizations or approvals of the Commission legally required for the issuance and sale of the Securities have been obtained; such orders are sufficient for the issuance and sale of the Securities in accordance with the terms of the Agreements; the issuance and sale of the Securities conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval pursuant to any Georgia or United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no

Schedule IV-3

opinion) is legally required for the issuance and sale of the Securities in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized by all necessary corporate action on the part of the Guarantor, executed and delivered by the Guarantor and is enforceable against the Guarantor and the Company in accordance with its terms, subject to the qualifications that the enforceability of the Guarantor’s and the Company’s obligations under the Indenture may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

5. The Notes, when the Global Note is authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

6. The Guarantee has been duly authorized by all necessary corporate action on the part of the Guarantor, executed and delivered by the Guarantor and is enforceable against the Guarantor in accordance with its terms, subject to the qualifications that the enforceability of the Guarantor’s obligations under the Guarantee may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

7. Each of the Indenture, the Guarantee and the Notes conforms as to legal matters in all material respects to the descriptions thereof in the Pricing Disclosure Package and the Final Supplemented Prospectus.

8. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

9. The execution and delivery by the Guarantor of the Underwriting Agreement, the Indenture, and the Guarantee, and the consummation of the transactions contemplated thereby, do not result in any violation of: (i) the charter or bylaws of the Guarantor or (ii) any existing applicable law, rule or regulation of the United States or the State of Georgia.

10. The execution and delivery by the Company of the Underwriting Agreement, the Indenture and the Global Note, and the consummation of the transactions contemplated thereby, do not result in any violation of any existing applicable law, rule or regulation of the United States or the State of Georgia.

11. The Company and the Guarantor are not and, after giving effect to the offering and sale of the Securities, neither will be an “investment company” or a company

Schedule IV-4

“controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

12. The statements set forth in the Pricing Disclosure Package and the Final Supplemented Prospectus under the heading “Certain United States Federal Income Tax Considerations for Non-U.S. Holders” insofar as they purport to constitute summaries of matters of United States federal income tax law, constitute accurate summaries in all material respects subject to the qualifications, limitations and assumptions set forth therein.

The attorneys in this firm that are rendering this opinion are members of the State Bar of Georgia and we do not purport to express any opinion herein concerning any law other than the law of the State of Georgia, the federal law of the United States and, to the extent set forth herein, the law of the State of New York.

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

We have participated in various conferences with the Company and the Guarantor, their representatives, representatives of the independent public or certified public accountants of the Guarantor, representatives of you and your counsel at which the contents of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents and related matters were discussed and reviewed. Because of the inherent limitations in the independent verification of factual matters, and the character of the determinations involved in the preparation of the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus and the Exchange Act Documents, we are not passing upon and do not assume any responsibility for, and make no representation that we have independently verified, the accuracy, completeness or fairness of the statements contained therein (other than as specified in opinion paragraph 7 related to the Indenture, the Guarantee and the Notes and paragraph 12 of our opinion to you dated of even date herewith). However, on the basis of the foregoing, we advise you that nothing has come to our attention which has caused us to believe that:

1. the Registration Statement, on the Effective Date (including the Exchange Act Documents on file with the Commission as of such date), contained any untrue statement of

Schedule IV-7

a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading,

2. the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

3. the Final Supplemented Prospectus (including the Exchange Act Documents) contained, as of its date, or contains, on the date hereof, any untrue statement of a material fact or omitted, as of its date, or omits, on the date hereof, to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading,

except that in each case we express no belief with respect to the Statement of Eligibility and Qualification under the Trust Indenture Act of 1939, as amended, on Form T-1 filed as an exhibit to the Registration Statement and the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents and with respect to information set forth in the Pricing Prospectus and the Final Supplemented Prospectus under the captions “Description of the Series 2020A Senior Notes ─ Book-Entry Only Issuance ─ The Depository Trust Company” and “Description of the Series 2020A Senior Notes – Global Clearance and Settlement Procedures.”

Subject to and on the basis of the foregoing, we further advise you that the Registration Statement, on the Effective Date, and the Final Supplemented Prospectus, as of August 17, 2020, complied as to form in all material respects with the relevant requirements of the Act and the applicable rules and regulations of the Commission thereunder and that each Exchange Act Document, as of its date of filing with the Commission, complied as to form in all material respects with the relevant requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder, except that in each case we express no belief as to the Statement of Eligibility and Qualification under the Trust Indenture Act of 1939, as amended, on Form T-1 filed as an exhibit to the Registration Statement and the financial statements and schedules and notes thereto or other financial or statistical data contained or incorporated by reference in (or omitted from) the Registration Statement, the Pricing Disclosure Package, the Final Supplemented Prospectus or the Exchange Act Documents.

This letter is rendered by us only to you and is solely for your benefit in your capacity as Representatives of the Underwriters in connection with the Underwriting Agreement and the transactions contemplated thereunder and may not be used, quoted or relied upon by you for any other purpose or relied upon by or furnished to any other person without our prior written consent.

Series 2020A 1.750% Senior Notes due January 15, 2031

Ladies and Gentlemen:

We have acted as counsel to ▇▇▇▇▇ Fargo Bank, National Association (“▇▇▇▇▇ Fargo”), in connection with the issuance by Southern Company Gas Capital Corporation (formerly known as AGL Capital Corporation) (the “Company”) of $500,000,000 aggregate principal amount of Series 2020A 1.750% Senior Notes due January 15, 2031 (the “Senior Notes”) and the related guarantee thereof by Southern Company Gas (formerly known as AGL Resources Inc.) (the “Guarantor”), pursuant to the Indenture, dated as of February 20, 2001 (the “Indenture”), among the Company, the Guarantor and ▇▇▇▇▇ Fargo, as successor trustee (in such capacity, the “Trustee”).

Schedule V-1

For purposes of this opinion, we have reviewed the Indenture and such other documents, records and papers, and satisfied ourselves as to such other matters, as we have deemed necessary or appropriate for this opinion. As to questions of fact material to this opinion, we have relied on certificates of ▇▇▇▇▇ Fargo and of public officials. In such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies or forms and the authenticity of the originals of such latter documents. We have assumed that ▇▇▇▇▇ Fargo has been duly formed and that the Indenture constitutes a valid and binding agreement of, and is enforceable in accordance with its terms against, the Company.

Based upon the foregoing and subject to the qualifications below, we are of the opinion that:

1) Based solely on a certificate from the Comptroller of the Currency, ▇▇▇▇▇ Fargo is a national banking association formed under the laws of the United States and is authorized thereunder to transact the business of banking and exercise fiduciary powers and perform its obligations under the Indenture.

2) The Indenture constitutes a valid and binding agreement of ▇▇▇▇▇ Fargo enforceable against ▇▇▇▇▇ Fargo in accordance with its terms, except as may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law) and by an implied covenant of reasonableness, good faith and fair dealing.

We are members of the Bar of the State of New York and, for purposes of this opinion, do not hold ourselves out as experts on the laws of any jurisdiction other than the State of New York and the federal law of the United States. The opinions expressed herein are based as to matters of law solely on applicable provisions of the following, as currently in effect: (i) as to the opinions expressed in paragraphs (1) and (2), the National Bank Act and the regulations of the Office of the Comptroller of the Currency published in 12 C.F.R. Parts 1-199 and (ii) as to the opinion expressed in paragraph (2), subject to the exclusions and limitations set forth in this opinion letter, internal New York law.

This opinion is solely for your benefit in connection with the issuance and sale by the Company of the Senior Notes and may not be relied upon by you for any other purpose, or relied upon or furnished to any other person, without our prior written consent, except that copies of this opinion may be furnished to, but not relied upon by, (i) your independent auditors, advisors and legal counsel, or (ii) any person in order to comply with any subpoena, order, regulation, ruling or request of any judicial, administrative, governmental, supervisory or legislative body or committee or any self-regulatory body.

Ladies and Gentlemen:

We have acted as counsel to you in connection with (i) the issuance and sale by Southern Company Gas Capital Corporation (the “Company”) of $500,000,000 aggregate principal amount of its Series 2020A 1.750% Senior Notes due January 15, 2031 (the “Notes”) and the related guarantee thereof (the “Guarantee” and, together with the Notes, the “Securities”) by Southern Company Gas (the “Guarantor”) pursuant to an Indenture (the “Indenture”) dated as of February 20, 2001, by and among the Company, as issuer, the Guarantor, as guarantor, and ▇▇▇▇▇ Fargo Bank, National Association (as successor to The Bank of New York Mellon Trust Company, N.A.), as trustee (the “Trustee”); and (ii) the purchase by the Underwriters (as hereinafter defined) of the Notes pursuant to the terms of an Underwriting Agreement dated August 17, 2020 (the “Underwriting Agreement”), among the Company, the Guarantor and the Underwriters named in Schedule I thereto (the “Underwriters”) for whom you are acting as representatives (the “Representatives”). This opinion is being delivered to you as Representatives pursuant to Section 6(b)(4) of the Underwriting Agreement.

All capitalized terms not otherwise defined herein shall have the meanings set forth in the Underwriting Agreement.

Schedule VI-1

In rendering the opinions expressed below, we have examined the following documents:


a)	The Company’s and the Guarantor’s registration statement on Form S-3 (File Nos. 333-231185 and 333-231185-01) pertaining to the Notes, the Guarantee and certain other securities filed by the Company and the Guarantor under the Securities Act of 1933, as amended (the “Act”), as it became effective under the Act (the “Registration Statement”);


e)	An executed copy of the Indenture;


f)	An executed copy of the Guarantee;


g)	An executed copy of the Underwriting Agreement;


h)	The free writing prospectus prepared by the Company and the Guarantor and filed with the Commission on August 17, 2020 pursuant to Rule 433 under the Act (the “Permitted Free Writing Prospectus”); and


i)	The Company’s and the Guarantor’s charter and bylaws.

The documents listed in Schedule II-A to the Underwriting Agreement, taken together, are collectively referred to as the “Pricing Disclosure Package.”

Schedule VI-2

In addition, we have examined, and have relied as to factual matters upon, the documents delivered to you at the closing (except the certificate representing the Notes, of which we have examined a specimen), and we have made such other and further investigations as we deemed necessary to express the opinions hereinafter set forth. In such examination, we have assumed (i) the genuineness of all signatures, (ii) the legal capacity of natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such latter documents.

The Indenture and the Underwriting Agreement are herein referred to collectively as the “Agreements.”

Based upon the foregoing, and subject to the qualifications and limitations stated herein, we are of the opinion that:

2. The execution, delivery and performance by the Company and the Guarantor of the Underwriting Agreement have been duly authorized by all necessary corporate action, and the Underwriting Agreement has been duly executed and delivered by the Company and the Guarantor.

3. All orders, consents or other authorizations or approvals of the Commission legally required for the issuance and sale of the Securities have been obtained; such orders are sufficient for the issuance and sale of the Securities in accordance with the terms of the Agreements; the issuance and sale of the Securities conform in all material respects with the terms of such orders; and no other order, consent or other authorization or approval of any New York or United States governmental body (other than in connection or in compliance with the provisions of the securities or “blue sky” laws of any jurisdiction, as to which we express no opinion) is legally required for the issuance and sale of the Securities in accordance with the terms of the Underwriting Agreement.

4. The Indenture has been duly authorized, executed and delivered by the Company and the Guarantor and, assuming the due authorization, execution and delivery thereof by the Trustee, constitutes a valid and legally binding instrument of the Company and the Guarantor, enforceable against the Company and the Guarantor in accordance with its terms, subject to the qualifications that the enforceability of the Company’s and the Guarantor’s obligations under the Indenture may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Schedule VI-3

5. The Notes have been duly authorized and executed by the Company and, when authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Underwriters pursuant to the Underwriting Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the qualifications that the enforceability of the Company’s obligations under the Notes may be limited or otherwise affected by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

6. The Guarantee has been duly authorized by all necessary corporate action on the part of the Guarantor, executed and delivered by the Guarantor and is enforceable against the Guarantor in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

8. The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

9. The execution and delivery by the Company and the Guarantor of the Underwriting Agreement, the Indenture, the Guarantee and the Notes, and the consummation of the transactions contemplated thereby, do not result in any violation of (i) the charter or bylaws of the Company or the Guarantor or (ii) any existing applicable law, rule or regulation of the United States or the State of New York.

We do not purport to express any opinion herein concerning any law other than the laws of the State of New York and the federal laws of the United States and, to the extent set forth herein, the laws of the State of Georgia. As to all matters governed by or dependent upon the laws of the State of Georgia, we have, with your consent, relied upon the opinion of ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ LLP dated the date hereof and addressed to you. As to all matters governed by or dependent upon the laws of the State of Nevada, we have, with your consent, relied upon the opinion of ▇▇▇▇▇▇▇▇ and Wedge dated the date hereof and addressed to you.
