ISSUANCE AND SALE OF COMMON STOCK

Section 2.01 Issuance.

(a) Upon the terms and subject to the conditions of this Agreement, the Company may sell Common Shares through BNYMCM and BNYMCM shall use its commercially reasonable efforts to sell Common Shares, up to the Maximum Program Amount, based on and in accordance with such number of Issuance Notices as the Company, in its sole discretion, shall choose to deliver during the Commitment Period until the aggregate number of Common Shares sold under this Agreement equals the Maximum Program Amount or this Agreement is otherwise terminated. Subject to the foregoing and the other terms and conditions of this Agreement, upon the delivery of an Issuance Notice, and unless the sale of the Common Shares described therein has been suspended, cancelled or otherwise terminated in accordance with the terms of this Agreement, BNYMCM will use its commercially reasonable efforts consistent with its normal trading and

sales practices to sell such Common Shares up to the Issuance Amount specified in such Issuance Notice, and otherwise in accordance with the terms of such Issuance Notice. BNYMCM will provide written confirmation to the Company no later than the opening of the Trading Day next following the Trading Day on which it has made sales of Common Shares hereunder setting forth the portion of the Actual Sold Amount for such Trading Day, the corresponding Sales Price and the Issuance Price payable to the Company in respect thereof.

The Company acknowledges and agrees that (i) there can be no assurance that BNYMCM will be successful in selling Common Shares and (ii) BNYMCM will incur no liability or obligation to the Company or any other Person if it does not sell Common Shares for any reason other than a failure by BNYMCM to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such Common Shares as required under this Section 2.01. In acting hereunder, BNYMCM will be acting as agent for the Company and not as principal.

(b) Method of Offer and Sale. The Common Shares may be offered and sold by any method permitted by law and deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act. The Common Shares may also be offered and sold to or through a market maker or in privately negotiated transactions, provided the parties hereto have so agreed in writing and if so provided in the “Plan of Distribution” section of the Prospectus or a further supplement to the Prospectus describing the terms of such negotiated transaction. Nothing in this Agreement shall be deemed to require either party to agree to the offering and sale of Common Shares to or through a market maker or in privately negotiated transactions and either party may withhold its consent thereto in its sole discretion.

(c) Issuances. Upon the terms and subject to the conditions set forth herein, on any Trading Day as provided in Section 2.03(b) hereof during the Commitment Period on which the conditions set forth in Section 5.01 and 5.02 hereof have been satisfied, the Company may exercise an Issuance by the delivery of an Issuance Notice, executed by the Chief Executive Officer, President, Chief Financial Officer, Vice President/Finance/Treasurer, Corporate Secretary, and Assistant Corporate Secretary of the Company (each, an “Authorized Officer”), to BNYMCM.

On any Trading Day during the Commitment Period, the Company may deliver an Issuance Notice to BNYMCM, subject to the satisfaction of the conditions set forth in Sections 5.01 and 5.02; provided, however, that, notwithstanding anything in this Agreement to the contrary, BNYMCM shall have no further obligations with respect to any Issuance Notice if and to the extent the number of Common Shares to be sold pursuant thereto, together with the aggregate number of the Common Shares previously sold under this Agreement shall exceed the Maximum Program Amount.

(c) Floor Price. BNYMCM shall not sell Common Shares below the Floor Price during any Selling Period, as such Floor Price may be adjusted by the Company at any time during any Selling Period upon notice to BNYMCM and confirmation to the Company.

(d) Trading Guidelines. BNYMCM may, to the extent permitted under the Securities Act and the Exchange Act, purchase and sell Common Stock for its own account while this Agreement is in effect provided that (i) no such purchase or sale shall take place while an Issuance Notice is in effect (except to the extent that, if the parties have agreed in writing that sales may be made to or through a market maker or in privately negotiated transactions, BNYMCM may engage in sales of Common Shares purchased or deemed purchased from the Company as a “riskless” principal or in a similar capacity), (ii) in no circumstances shall BNYMCM have a short position in the Common Stock for its own account and (iii) the Company shall not be deemed to have authorized or consented to any such purchases or sales by BNYMCM. In addition, the Company

hereby acknowledges and agrees that BNYMCM’s Affiliates, subject to compliance with Regulation M under the Exchange Act, may make markets in the Common Stock or other securities of the Company, in connection with which they may buy and sell, as agent or principal, for long or short account, shares of Common Stock or other securities of the Company, at the same time BNYMCM is acting as agent pursuant to this Agreement.

Section 2.04 Use of Free Writing Prospectuses. Neither the Company nor BNYMCM has prepared, used, referred to or distributed, or will prepare, use, refer to or distribute any “written communication” which constitutes a “free writing prospectus” without the other party’s written consent, as such terms are defined in Rule 405 under the Securities Act.

Section 2.05 Settlements. Subject to the provisions of Article V, on or before each Settlement Date, the Company will cause EQ Shareowner Services, its transfer agent, to electronically transfer the Common Shares being sold by crediting BNYMCM or its designee’s account at DTC through its Deposit/Withdrawal At Custodian (DWAC) System, or by such other means of delivery as may be mutually agreed upon by the parties hereto and concurrently with the receipt of such Common Shares, which in all cases shall be freely tradable, transferable, registered shares in good deliverable form, BNYMCM will deliver the related Issuance Price in same day funds delivered to an account designated by the Company prior to the Settlement Date. If the Company defaults in its obligation to deliver Common Shares on a Settlement Date, the Company agrees that it will (a) hold BNYMCM harmless against any loss, claim, damage or expense (including, without limitation, penalties, interest and reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by the Company, and (b) pay to BNYMCM any Selling Commission to which it would otherwise have been entitled absent such default. The individuals listed on Schedule 1 hereto shall be the contact persons for all matters related to the settlement of the transfer of Common Shares through the DWAC System for purposes of this Section 2.05.

Section 2.07 Exemption from Regulation M. If BNYMCM reasonably believes that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act (applicable to securities with an average daily trading volume value of at least $1,000,000 that are issued by an issuer whose common equity securities have a public float value of at least $150,000,000) are not satisfied with respect to the Company or the Common Shares, it shall promptly notify the Company of such belief and sales of Common Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the reasonable judgment of both parties. If, either immediately prior to delivery of an Issuance Notice or during a Selling Period, the Company reasonably believes that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Company or the Common Shares, it shall promptly notify BNYMCM of such belief and sales of Common Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the reasonable judgment of both parties.

The execution and delivery by the Company of, and the performance by each of its obligations under, this Agreement will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the imposition of a lien or security interest under, any material indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any Material Subsidiary is a party or by which the Company or any Material Subsidiary is bound or to which any of the property or assets used in the conduct of the business of the Company or any Material Subsidiary is subject, (b) result in any violation of the provisions of the Articles of Incorporation, Certificate of Incorporation, as applicable, or the bylaws of the Company or the organizational documents of any Material Subsidiary, or (c) result in any violation of any applicable statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any Material Subsidiary or any of their properties (except in each case for conflicts, breaches, violations, defaults, liens or security interests that would not have a Material Adverse Effect). No consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body is required for the performance by the Company of its obligations under this Agreement, except (1) such as have been, or will have been prior to the Closing Date, obtained under the Securities Act, (2) such as have been, or will have been obtained in connection with the Reincorporation prior to the Reincorporation Date to the extent the Reincorporation Date has not occurred, and to the extent the Reincorporation Date has occurred, such as have been obtained in connection with the Reincorporation, and (3) for such consents, approvals, authorizations, orders, registrations or qualifications as may be required under state securities or blue sky laws, as the case may be, and except in any case where the failure to obtain such consent, approval, authorization, order, registration or qualification would not have a Material Adverse Effect.

Section 3.09 Legal Proceedings. Other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its Subsidiaries is a party or of which any property of the Company or any of its Subsidiaries is the subject which, if determined adversely to the Company or any of its Subsidiaries, would individually or in the aggregate have a Material Adverse Effect and, to the best of the Company’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

Section 3.10 Sale of Common Shares. Immediately after any sale of Common Shares by the Company hereunder, the aggregate amount of Common Stock that has been issued and sold by the Company hereunder will not exceed the aggregate amount of Common Stock (a) registered under the Registration Statement or (b) that shall be authorized by the CPUC from time to time (in this regard, the Company acknowledges and agrees that BNYMCM shall have no responsibility for maintaining records with respect to the aggregate amount of Common Shares sold, or of otherwise monitoring the availability of Common Stock for sale, under the Registration Statement or applicable CPUC authorizations).

Each of the Company and the Material Subsidiaries has such permits, licenses, franchises and authorizations of governmental or regulatory authorities (collectively, the “permits”) as are necessary to own its respective properties and to conduct its business in the manner described in the Prospectus, except where the failure to obtain such permits would not reasonably be expected to have a Material Adverse Effect; to the best knowledge of the Company after due inquiry, each of the Company and the Material Subsidiaries has fulfilled and performed all its material obligations with respect to such permits, except where the failure to fulfill or perform any such obligation would not reasonably be expected to have a Material Adverse Effect; and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination of any material permits or would result in any other material impairment of the rights of the holder of any such material permits, subject in each case to such qualifications as may be set forth in the Prospectus.

Section 3.12 Investment Company. The Company is not, and after giving effect to the offering and sale of the Common Shares, will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(a) The financial statements, together with related schedules and notes, included or incorporated by reference in the Registration Statement and the Prospectus, present fairly, in all material respects, the consolidated financial position, results of operations and changes in financial position of Southwest Gas Corporation (the “Predecessor”) or the Company, as applicable, and the Subsidiaries on the basis stated in the Registration Statement and the Prospectus at the respective dates or for the respective periods to which they apply; such statements and related schedules and notes have been prepared in accordance with generally accepted accounting principles consistently applied throughout the periods involved, subject to normal year-end adjustments, except as disclosed therein; and the other financial and statistical information and data included or incorporated by reference in the Registration Statement and the Prospectus are accurately presented and prepared on a basis consistent with such financial statements and the books and records of the Predecessor or the Company, as applicable, and the Subsidiaries. No other financial statements are required to be set forth or to be incorporated by reference in the Registration Statement or the Prospectus under the Securities Act.

(b) The Company and its Subsidiaries maintain systems of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to

permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (v) material information relating to the Company and its Subsidiaries is made known to the Company by its officers and employees. The Company’s internal control over financial reporting was effective as of December 31, 2018, and the Company is not aware of any material weaknesses therein. Since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially adversely affected, or is reasonably likely to materially adversely affect, the Company’s internal control over financial reporting.

(c) The accountants who have audited the financial statements of the Company or the Predecessor that are incorporated by reference in the Registration Statement and the Prospectus and who have audited the Company’s or the Predecessor’s internal control over financial reporting are independent registered public accountants as required by the Securities Act and the rules and regulations of the Commission thereunder and the Public Company Accounting Oversight Board.

Section 3.14 Use of Proceeds. The Company will use the net proceeds from the offering of Common Shares in the manner specified in the Prospectus under “Use of Proceeds.”

Section 3.15 Environmental Matters. Other than as set forth in the Prospectus, (a) the Company and its Subsidiaries are in compliance in all material respects with all applicable state and federal environmental laws, except for instances of noncompliance that, individually or in the aggregate, would not have a Material Adverse Effect, and (b) no event or condition has occurred that is reasonably likely to interfere in any material respect with the compliance by the Company and its Subsidiaries with any environmental law or that is reasonably likely to give rise to any liability under any environmental law, in each case that, individually or in the aggregate, would have a Material Adverse Effect.

Section 3.16 eXtensible Business Reporting Language. The Company’s disclosure controls and procedures provide reasonable assurance that the interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement and the Prospectus is prepared in accordance with the Commission’s rules and guidelines applicable thereto. The interactive data in eXtensible Business Reporting Language incorporated by reference in the Registration Statement and the Prospectus fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto in all material respects.

Section 3.17 Insurance. Each of the Company and its Subsidiaries is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent.

Except under circumstances where the Company has provided BNYMCM with notice that it reasonably believes that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Company or the Common Shares (in which case any sales of Common Shares under this Agreement shall be suspended in the manner provided for in Section 2.07 of this Agreement), the Common Stock is an “actively traded security” exempted from the requirements of Rule 101 of Regulation M under the Exchange Act by subsection (c)(1) of such rule.

ARTICLE VI

INDEMNIFICATION AND CONTRIBUTION

Section 6.01 Indemnification by the Company. The Company agrees to indemnify and hold harmless BNYMCM, its officers, directors, employees and agents, and each Person, if any, who controls BNYMCM within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, together with each such Person’s respective officers, directors, employees and agents (collectively, the “Controlling Persons”), from and against any and all losses, claims, damages or liabilities, and any action or proceeding in respect thereof, to which BNYMCM, its officers, directors, employees and agents, and any such Controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus or any other prospectus relating to the Common Shares (including a Free Writing Prospectus), or any amendment or supplement thereto, or any preliminary 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 (in the case of the Prospectus or any amendment or supplement thereto or any preliminary prospectus, in light of the circumstances in which they were made) not misleading, except insofar as the same are made (i) in reliance upon and in conformity with information related to BNYMCM or its plan of distribution furnished in writing to the Company by BNYMCM expressly for use therein, or (ii) in a Free Writing Prospectus used by BNYMCM in violation of Section 2.04, and the Company shall reimburse BNYMCM, its officers, directors, employees and agents and each Controlling Person for any reasonable legal and other expenses incurred thereby in investigating or defending or preparing to defend against any such losses, claims, damages or liabilities, or actions or proceedings in respect thereof, as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such losses, claims, damages or liabilities, or any action or proceeding, arise out of or are based upon an untrue statement or omission contained in the Registration Statement, the Prospectus or any other prospectus relating to the Common Shares, or any amendment thereto, if (x) such untrue statement or omission or alleged untrue statement or omission is corrected in an amendment or supplement to such prospectus and (y) having previously been furnished by or on behalf of the Company with copies of such prospectus as so amended or supplemented, BNYMCM thereafter fails to deliver such prospectus as so amended or supplemented (in such cases where BNYMCM is legally required to deliver a prospectus) prior to the transaction giving rise to the claims from which such losses, claims, damages or liabilities, or action or proceeding arise.

Section 6.02 Indemnification by BNYMCM. BNYMCM agrees to indemnify and hold harmless the Company, its officers, directors, employees and agents and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, together with each such Person’s respective officers, directors, employees and

agents, from and against any losses, claims, damages or liabilities, and any action or proceeding in respect thereof, to which the Company, its officers, directors, employees or agents, any such controlling Person and any officer, director, employee or agent of such controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as losses, claims, damages or liabilities (or action or proceeding in respect thereof) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus or any other prospectus relating to the Common Shares (including a Free Writing Prospectus), or any amendment or supplement thereto, or any preliminary 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 (in the case of the Prospectus or any other prospectus relating to the Common Shares, or any amendment or supplement thereto or any preliminary prospectus, in light of the circumstances in which they were made) 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 therein (a) in reliance upon and in conformity with written information related to BNYMCM or its plan of distribution furnished to the Company by BNYMCM expressly for use therein, or (b) in a Free Writing Prospectus used by BNYMCM in violation of Section 2.04, and BNYMCM shall reimburse the Company, its officers, directors, employees and agents, and each controlling Person of the Company for any reasonable legal and other expenses incurred thereby in investigating or defending or preparing to defend against any such losses, claims, damages or liabilities, or actions or proceedings in respect thereof, as such expenses are incurred.

Section 6.03 Conduct of Indemnification Proceedings. As promptly as reasonably practicable after receipt by any Person (an “Indemnified Party”) of notice of any claim or the commencement of any action in respect of which indemnity may be sought pursuant to Section 6.01 or 6.02, the Indemnified Party shall, if a claim in respect thereof is to be made against the Person against whom such indemnity may be sought (an “Indemnifying Party”), notify the Indemnifying Party in writing of the claim or the commencement of such action. In the event an Indemnified Party shall fail to give such notice as provided in this Section 6.03 and the Indemnifying Party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, the indemnification provided for in Sections 6.01 or 6.02 shall be reduced to the extent of any actual prejudice resulting from such failure to so notify the Indemnifying Party; provided, that the failure to notify the Indemnifying Party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under Section 6.01 or 6.02. If any such claim or action shall be brought against an Indemnified Party, the Indemnifying Party shall be entitled to participate therein, and, to the extent that it wishes, jointly with any other similarly notified Indemnifying Party, to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided that the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party, but the fees and expenses of such counsel shall be for the account of such Indemnified Party unless (a) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (b) such Indemnified Party reasonably concludes that representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest with the

Company, it being understood, however, that the Indemnifying Party shall not, in connection with any one such claim or action or separate but substantially similar or related claims or actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for all Indemnified Parties or for fees and expenses that are not reasonable. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnification could have been sought hereunder by such Indemnified Party unless such settlement includes an unconditional release of each such Indemnified Party from all losses, claims, damages or liabilities arising out of such claim or proceeding and such settlement does not admit or constitute an admission of fault, guilt, failure to act or culpability on the part of any such Indemnified Party. Whether or not the defense of any claim or action is assumed by an Indemnifying Party, such Indemnifying Party will not be subject to any liability for any settlement made without its prior written consent, which consent will not be unreasonably withheld.

Section 6.04 Contribution. If for any reason the indemnification provided for in this Article VI is unavailable to the Indemnified Parties in respect of any losses, claims, damages or liabilities referred to herein, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities as between the Company, on the one hand, and BNYMCM, on the other hand, in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand and BNYMCM on the other hand from the offering of the Common Shares to which such losses, claims, damages or liabilities relate. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each Indemnifying Party shall contribute to such amount paid or payable by such Indemnifying Party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of BNYMCM in connection with such statements or omissions, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and by BNYMCM, on the other, shall be deemed to be in the same proportion as the total net proceeds from the sale of Common Shares (before deducting expenses) received by the Company bear to the total commissions received by BNYMCM in respect thereof. The relative fault of the Company, on the one hand, and of BNYMCM, 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 on one hand or by BNYMCM on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and BNYMCM agree that it would not be just and equitable if contribution pursuant to this Section 6.04 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6.04, BNYMCM shall in no

event be required to contribute any amount in excess of the commissions received by it under this Agreement. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6.04 each officer, director, employee and agent of BNYMCM, and each Controlling Person, shall have the same rights to contribution as BNYMCM, and each director of the Company, each officer of the Company who signed the Registration Statement, and each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The obligations of the Company and BNYMCM under this Article VI shall be in addition to any liability that the Company and BNYMCM may otherwise have.

Section 7.04 Liability; Provisions that Survive Termination. If this Agreement is terminated pursuant to this Article VII, such termination shall be without liability of any party to any other party except as provided in Section 9.02 and for the Company’s obligations in respect of all prior Issuance Notices, and provided further that in any case the provisions of Article VI, Article VIII and Article IX shall survive termination of this Agreement without limitation.

ARTICLE VIII
