Form of Change in Control Agreement with Company Officers

 Exhibit 10.01 
 CHANGE IN CONTROL AGREEMENT 
 THIS CHANGE IN CONTROL AGREEMENT (this
“Agreement”) entered into and effective as of the [•] day of [•] between SOUTHWEST GAS CORPORATION, a California corporation (together with its successors, the “Company”), and [•] (the
“Executive”). 
 WHEREAS, the Board of Directors of the Company (the “Board”) recognizes that
the continuing possibility of a change in control of the Company is unsettling to the Executive and other officers of the Company; 
 WHEREAS, the Board wishes to assure a continuing dedication by the Executive to his duties to the Company, notwithstanding the occurrence or potential occurrence of a change in control of the Company;

 WHEREAS, the Board believes it is important, should the Company receive proposals from third parties with respect to its
future, to enable the Executive, without being influenced by the uncertainties of his own situation, to assess and advise the Board whether such proposals would be in the best interests of the Company and its shareholders and to take such other
action regarding such proposals as the Board might determine to be appropriate; and 
 WHEREAS, the Board wishes to demonstrate
to officers of the Company that the Company is concerned with the welfare of its officers and intends to see that loyal officers are treated fairly. 
 NOW, THEREFORE, the Company and the Executive agree as follows: 
  

	1.	TERM 

 The term of this Agreement
shall commence on the date first set forth above and shall end on the third (3rd) anniversary thereof. Notwithstanding the foregoing, this Agreement shall not terminate during the Protection Period or the Severance Period, in each case as
defined below. 
  

	2.	DEFINITIONS 

 As used in this
Agreement: 
 (a) “Cause” means (i) a material act of theft, misappropriation, or conversion of corporate
funds committed by the Executive or (ii) the Executive’s demonstrably willful, deliberate and continued failure to follow reasonable directives of the Board or the Chief Executive Officer of the Company which are within the
Executive’s ability to perform. The Executive shall not be deemed to have been terminated for Cause unless and until: (x) there shall have been delivered to the Executive a copy of a resolution duly

 
adopted by the Board in good faith at a meeting of the Board called and held for such purpose (after reasonable notice to the Executive and an opportunity for the Executive, together with his
counsel, to be heard before the Board) finding that the Executive was guilty of conduct set forth above and specifying the particulars thereof in reasonable detail; and (y) if the Executive contests such finding (or a conclusion that he has
failed to timely cure the performance in response thereto), the arbitrator, by final determination in an arbitration proceeding pursuant to Section 5 hereof, has concluded that the Executive’s conduct met the standard for termination for
Cause above and that the Board’s conduct met the standards of good faith and satisfied the procedural and substantive conditions of this Section 2(a) (collectively, the “Necessary Findings”). The Executive’s costs of
the arbitration shall be advanced by the Company and shall be repaid to the Company if the arbitrator makes the Necessary Findings. 
 If within sixty (60) days after receipt by the Executive of the resolution referred to in the preceding paragraph, the Executive notifies the Company that a dispute exists concerning the termination,
the termination date of the Executive shall be the date as finally determined by mutual written agreement of the parties or by a final and binding arbitration award. During the period until the dispute is finally resolved, the Company will, in
accordance with its regular payroll procedures, continue to pay the Executive his full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, base salary) and continue the Executive as a
participant in all compensation, employee benefit, health and welfare and insurance plans, programs, arrangements and perquisites in which the Executive was participating or to which he was entitled when the notice giving rise to the dispute was
given, until the dispute is finally resolved. Amounts paid under this Section 2(a) shall be repaid to the Company or be offset against or reduce any other amounts due the Executive under this Agreement, if appropriate, only upon the final
resolution of the dispute. Notwithstanding the foregoing, if the Executive is a “specified employee” within the meaning of Section 409A of the Code and the related Treasury Regulations and guidance thereunder (“Section
409A”) on the date of termination of the Executive’s employment with the Company, during the six- (6-) month period following the Executive’s termination of employment with the Company, payments to the Executive under this
Section 2(a) (other than reimbursements and in-kind amounts described in Treasury Regulation Section 1.409A-1(b)(9)(v), or any successor provision thereto) that constitute “non-qualified deferred compensation” under
Section 409A shall be delayed and paid to the Executive on the first regularly scheduled Company executive pay date that occurs in the seventh (7th) calendar month following the calendar month in which the Executive’s termination of
employment occurs; thereafter, any additional payments owed to the Executive under this Section 2(a) shall be paid to the Executive ratably on the following regularly scheduled Company executive pay dates. 

(b) “Change in Control” means any of the following: 

(i) Approval by the shareholders of the Company of the dissolution or liquidation of the Company; 

  
 2 

 (ii) Consummation of a merger or consolidation, or other reorganization,
with or into one (1) or more entities that are not Subsidiaries, as a result of which less than 50% of the outstanding voting securities of the surviving or resulting entity immediately after such reorganization are, or shall be, owned,
directly or indirectly, by shareholders of the Company immediately before such reorganization (assuming for purposes of such determination that there is no change in the record ownership of the Company’s securities from the record date for such
approval until such reorganization and that such record owners hold no securities of the other parties to such reorganization, but including in such determination any securities of the other parties to such reorganization held by affiliates of the
Company); 
 (iii) Consummation of the sale of substantially all of the Company’s business and/or assets to
a person or entity which is not a Subsidiary; 
 (iv) Any “person” (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), but excluding any person described in and satisfying the conditions of Rule 13d-1(b)(1) thereunder), becomes the beneficial owner (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 20% of the combined voting power of the Company’s then outstanding securities entitled to then vote generally in the election of
directors of the Company; or 
 (v) During any period not longer than two (2) consecutive years, individuals
who at the beginning of such period constituted the Board cease to constitute at least a majority thereof, unless the election, or the nomination for election by the Company’s shareholders, of each new Board member was approved by a vote of at
least three-fourths (3/4) of the Board members then still in office who were Board members at the beginning of such period (including for these purposes, new members whose election was so approved). 

(c) “COBRA” means the Consolidated Omnibus Budget Reconciliation Act of 1986, as amended. 

(d) “Code” means the Internal Revenue Code of 1986, as amended. 

(e) “Disability” means that because of physical or mental illness or disability, the Executive shall have been
continuously unable to perform the essential functions of his job with or without reasonable accommodation for a consecutive period of at least six (6) months. 
 (f) “Good Reason” means, following a Change in Control: 
 (i) without the Executive’s express written consent, the assignment to him of any duties materially inconsistent with his positions, duties, authority,

  
 3 

 
responsibilities or status with the Company immediately prior to such Change in Control; 
 (ii) a material demotion or a material change in the Executive’s titles or offices as in effect immediately prior to such Change in Control; 

(iii) any removal of the Executive from or any failure to re-elect him to any of such positions; except in connection with
the termination of the Executive’s employment for Cause, Disability or retirement or as a result of his death or by him other than for Good Reason; 
 (iv) without the Executive’s express written consent, a material reduction by the Company in the Executive’s base salary as in effect on the date of such Change in Control or, if greater, such
greater base salary as may be in effect from time to time subsequent to such Change in Control, provided, in each case, that a reduction by the Company in the Executive’s base salary of ten (10) percent or more shall be sufficient but not
necessary to constitute a material reduction by the Company in the Executive’s base salary; 
 (v) the
failure by the Company to continue at levels materially not less than those in existence immediately prior to such Change in Control the Executive’s participation in any thrift, incentive or compensation plan, or any pension plan, in which the
Executive participated immediately prior to such Change in Control, provided that the Company may provide for participation in substantially similar plans that provide benefits at levels materially not less than those in existence immediately prior
to such Change in Control; 
 (vi) the failure by the Company to provide for the Executive’s participation
in any welfare, life insurance, health and accident or disability plan on the same basis as those provided to executives of the Company who are similarly situated to the Executive; 

(vii) the taking of any action by the Company which would materially adversely affect the Executive’s participation
in or materially reduce his benefits under any single such plan or all such plans, when taken together, or deprive him of any material fringe benefit enjoyed by him at the time of such Change in Control (except for the acceleration of the
termination dates of stock options, restricted stock units, performance shares and other awards and rights, if applicable, as contemplated by this Agreement), provided that the taking of any action by the Company that reduces the economic value
attributable to such participation, benefits or fringe benefit by ten (10) percent or more shall be sufficient but not necessary to constitute a materially adverse effect, material reduction or deprivation, as applicable; 

(viii) the assignment to the Executive without his consent to a new work location which would require an increase in the
round-trip commute to work from 

  
 4 

 
the Executive’s residence immediately prior to such Change in Control of more than 40 miles per day; or 

(ix) any material breach of any material provision of this Agreement. 

Notwithstanding the foregoing, the Executive shall not be entitled to terminate his employment with the Company for Good Reason unless
the following process is followed with respect to such termination. Within ninety (90) days following the initial occurrence of an event that purportedly constitutes Good Reason, the Executive shall give the Company written notice of the
occurrence of such event, setting forth the exact nature of such event and the conduct required to cure such event. The Company shall have thirty (30) days from the receipt of such notice within which to cure such event (such period, the
“Cure Period”). If, during the Cure Period, such event is cured, then the Executive shall not be permitted to terminate his employment with the Company for Good Reason as a result of such event. If, at the end of the Cure Period,
such event is not cured, the Executive shall be entitled to terminate his employment with the Company for Good Reason as a result of such event during the sixty (60) day period following the end of the Cure Period. If the Executive does not
terminate his employment with the Company for Good Reason during such sixty (60) day period, the Executive shall not be permitted to terminate his employment with the Company for Good Reason as a result of such event. 

(g) “Subsidiary” means any corporation, partnership, joint venture or other entity in which the Company has a 50% or
greater equity interest. 
  

	3.	LIMITED RIGHT TO A SEVERANCE BENEFIT 

 The Executive shall be entitled to the severance benefits provided in this Section 3 if, within twenty-four (24) months after a Change in Control (the “Protection Period”):
(i) the Executive terminates his employment with the Company for Good Reason or (ii) the Executive’s employment is terminated by the Company for any reason other than (x) the Executive’s death, (y) the Executive’s
Disability or (z) Cause, in each case, for clauses (i) and (ii) immediately preceding, provided that the Executive executes and delivers to the Company within 45 days of the date of such termination, and lets become effective and
irrevocable, a Release in the form attached hereto as Attachment A (“Release”): 
 (a) Any restricted stock
awards, restricted stock units, stock options, stock appreciation rights or performance shares to purchase or relating to the common stock of the Company held by the Executive on the date of such termination, which are not then currently vested or
exercisable, shall on such date automatically become vested or exercisable and shall remain exercisable for 90 days thereafter (subject to any fixed term of such award, unit, option, right or share set forth in the document evidencing such award,
unit, option, right or share). 

  
 5 

 (b) A lump-sum severance payment equal to the sum of: 

(i) [30 (President and SVP)] OR [24 (VP)] months of the Executive’s yearly base salary in effect as of the
date of such termination or, if greater, as of the date of such Change in Control, and 
 (ii) an amount equal to
any incentive compensation that would be payable to the Executive under any short or long-term incentive compensation plan of the Company (including the Company’s Management Incentive Plan or any successor plan thereto and the Company’s
Restricted Stock Unit Plan or any successor plan thereto), calculated at the designated award opportunity for the Executive at the date of termination or, if greater, as of the date of such Change in Control, and at 100% of the target performance
measures, with any such amounts otherwise payable in securities of the Company to be payable in cash, for the period during the applicable plan year preceding the date of such termination and for the severance period of [30 (President and SVP)]
OR [24 (VP)] months following the date of such termination (such post-termination period, the “Severance Period”), and 
 (iii) an amount equal to the full cost of health and dental coverage for the Executive (and his eligible dependents) for the Severance Period, which amount shall be calculated based on the full cost of
continued health and dental coverage for the Executive (and his eligible dependents) under COBRA as of the date of termination or, if greater, as of the date of such Change in Control, and 

(iv) an amount equal to the full cost of replacement disability and life insurance coverage for the Executive (other than
travel/accident) for the Severance Period, which cost shall be calculated as of the date of termination or, if greater, as of the date of such Change in Control. 
 Subject to the limits in Section 3(e) below, payment of the foregoing lump-sum severance payment shall be made in accordance with the Company’s regular payroll procedures and be made to the
Executive on the first regularly scheduled Company executive pay date that occurs sixty (60) days after the termination of the Executive’s employment, provided that the Release has become effective and irrevocable. 

(c) The Company shall pay the Executive any benefits under the Company’s benefit plans, including the Company’s Executive
Deferred Compensation Plan and the Company’s Supplemental Executive Retirement Plan (the “SERP”), which are fully vested on the date of such termination, in accordance with their terms, including with respect to applicable
payment schedules and any applicable elections; provided, however, that, if the Executive shall have reached the age of fifty (50) by the date of such termination, the Executive shall receive additional benefits under the SERP such that the
Executive shall be permitted to add to the formula for purposes of eligibility for benefits, vesting and calculation of benefits, [6 (President and SVP)] OR [5 (VP)] points which, at the election of the Executive, may be applied either to an
age assumption or continuous length of service assumption or a combination thereof. 

  
 6 

 (d) The Executive shall be entitled to reimbursement of reasonable expenses actually
incurred by the Executive directly related to outplacement services, which reimbursement shall not exceed Thirty Thousand Dollars ($30,000). Such reimbursement shall only be made for outplacement services directly related to such termination. Such
expenses must be incurred not later than the end of the second calendar year following the calendar year of such termination. Such expense must be submitted by the Executive to the Company as promptly as practicable, and in no event later than
required by the Company in order for the Company to make such reimbursement no later the last day of the third calendar year following the calendar year in which such termination occurs. In no event shall the Company make any such reimbursement
later than the last day of the third calendar year following the calendar year in which such termination occurs. 
 (e)
Notwithstanding anything to the contrary in this Section 3, if the Executive is a “specified employee” within the meaning of Section 409A, during the six- (6-) month period following the Executive’s termination of employment
with the Company, payments to the Executive under this Section 3 (other than reimbursements and in-kind amounts described in Treasury Regulation Section 1.409A-1(b)(9)(v) or any successor provision thereto) that constitute
“non-qualified deferred compensation” under Section 409A shall be delayed and paid to the Executive on the first regularly scheduled Company executive pay date that occurs in the seventh (7th) calendar month following the
calendar month in which the Executive’s termination of employment occurs; thereafter, any additional payments owed to the Executive under this Section 3 shall be paid to the Executive in the manner otherwise specified in this
Section 3. With respect to any payment delayed pursuant to this Section 3(e), the Company shall pay the Executive, on the day on which such delayed payment is made to the Executive, interest on such delayed payment for the period of such
delay at the applicable federal rate provided for in Section 1274(d) of the Code for the month in which such delayed payment otherwise would have been made. 
 (f) For purposes of this Agreement, the Executive will be deemed to not have terminated employment with the Company unless the Executive has incurred a Separation from Service. “Separation from
Service” means the termination of the Executive’s employment by the Company if the Executive dies, retires or otherwise has a termination of employment with the Company; provided that the Executive’s employment relationship is
treated as continuing intact while on military leave, sick leave or other bona fide leave of absence if the period of such leave does not exceed six (6) months or longer, if the Executive’s right to reemployment is provided either by
statute or by contract. A leave of absence constitutes a bona fide leave of absence only if there is a reasonable expectation that the Executive will return to perform services for the Company. If the period of leave exceeds six (6) months and
the Executive does not retain a right to reemployment under an applicable statute or by contract, the employment relationship is deemed to terminate on the first date immediately following such six- (6-) month period. Notwithstanding the foregoing,
where a leave of absence is due to any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than six (6) months,

  
 7 

 
where such impairment causes the employee to be unable to perform the duties of his or her position of employment, or any substantially similar position of employment, a twenty-nine (29-) month
period of absence may be substituted for such six- (6-) month period. For purposes of this paragraph, the term “Company” includes all other organizations that together with the Company are part of a control group of organizations
under Section 414(b) and Section 414(c) of the Code. Whether an Executive has incurred a Separation from Service shall be determined based in accordance with Section 409A. Additionally, if the Executive ceases to work as an Executive,
but is retained to provide services as an independent contractor of the Company, the determination of whether the Executive has incurred a Separation from Service shall be determined based in accordance with Section 409A. 

 

	4.	CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY 

 In the event that it is determined that any payment or distribution by the Company to the Executive or for the Executive’s benefit, whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or pursuant to or by reason of any other agreement, policy, plan, program or arrangement, including without limitation any stock option or restricted stock or similar right, or the lapse or termination of any restriction
on or the vesting or exercisability of any of the foregoing (a “Payment”), would be subject to the excise tax imposed by Section 4999 of the Code (or any successor provision thereto), by reason of being considered “contingent on
a change in the ownership or effective control” of the Company, within the meaning of Section 280G of the Code (or any successor provision thereto) or to any similar tax imposed by state or local law, or any interest or penalties with
respect to such tax (such tax or taxes, together with any such interest and penalties, being hereafter collectively referred to as the “Excise Tax”), then the Payment shall be reduced by the Company in a manner determined by the Company to
be $1.00 less than three (3) times the Executive’s base amount (as defined in Section 280G of the Code) so that no portion of the Payment shall be subject to the Excise Tax, provided that the Company shall make such reduction only if
such reduction would effect, on an after-tax basis, a Payment that is greater than the Payment that would be made if no such reduction were effected. The Executive shall be permitted to provide the Company with written notice specifying which of the
Payments will be subject to reduction or elimination; provided, however, that to the extent that the Executive’s ability to exercise such authority would cause any Payment to become subject to any taxes or penalties pursuant to
Section 409A, or if the Executive does not provide the Company with any such written notice, the Company shall reduce or eliminate the Payments by first reducing or eliminating the portion of the Payments that are payable in cash and then by
reducing or eliminating the non-cash portion of the Payments, in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time. Except as set forth in the preceding sentence, any notice given by the
Executive pursuant to the preceding sentence shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive’s rights and entitlements to any benefits or compensation.

	5.	ARBITRATION AND LITIGATION 

 Any
dispute, controversy or claim arising out of or in respect to this Agreement (or its validity, interpretation or enforcement) or the subject matter hereof must be submitted to and settled by arbitration conducted before a single arbitrator or, at
the election of the Company or the Executive, a panel of arbitrators (chosen from a list of arbitrators provided by the American Arbitration Association with each party hereto taking alternate strikes and the remaining arbitrator or arbitrators, as
applicable, hearing the dispute). 
 By agreeing to arbitrate all disputes related to this Agreement, the Company and the
Executive acknowledge, among other things, that they are waiving the right to have the dispute heard by a court of law or equity and the right to a jury trial. 
 The arbitration will be conducted in Clark County, Nevada, in accordance with the then current rules of the American Arbitration Association or its successor. The arbitration of such issues, including the
determination of any amount of damages suffered, will be final and binding upon the parties to the maximum extent permitted by law. The decision of the arbitrator or the panel, as applicable, shall be in writing and signed by the arbitrator. A copy
of the arbitrator’s or the panel’s decision, as applicable, will be provided to each party. The arbitrator or panel, as applicable, in such action will not be authorized to change or modify any provision of this Agreement. Judgment upon
the award rendered by the arbitrator or the panel, as applicable, may be entered by any court having jurisdiction thereof. The parties consent to the jurisdiction of the Supreme Court of the State of Nevada and of the U.S. District Court for the
District of Nevada for all purposes in connection with arbitration, including the entry of judgment of any award. 
 The Company
shall advance the arbitrator’s or the panel’s fees, as applicable, subject to the provisions of Section 2(a), however, the arbitrator or the panel, as applicable, will award reasonable legal fees and expenses (including arbitration
costs) to the prevailing party upon application therefor. The non-prevailing party may thus incur greater expenses under arbitration than under traditional court litigation. 
 Except as may be necessary to enter judgment upon the award or to the extent required by applicable law, all claims, defenses and proceedings (including, without limiting the generality of the foregoing,
the existence of the controversy and the fact that there is an arbitration proceeding) shall be treated in a confidential manner by the arbitrator or the panel, as applicable, the parties and their counsel, and each of their agents and employees,
and all others acting on behalf or in concert with them. Without limiting the generality of the foregoing, no one shall divulge to any third party or person not directly involved in the arbitration, the contents of the pleadings, papers, orders,
hearings, trials, or awards in the arbitration, except as may be necessary to enter judgment upon an award as required by applicable law. Any court proceedings relating to the arbitration hereunder, including, without limiting the generality of the
foregoing, to prevent or compel arbitration to perform, correct, vacate or otherwise enforce an arbitration award, shall be filed under seal with the court, to the extent permitted by law. 

  
 9 

	6.	BENEFITS AND BINDING EFFECT 

This Agreement shall inure to the benefit of and be binding upon the Company, its successors and assigns, including but not limited to any
corporation, person or other entity which may acquire all or substantially all of the assets and business of the Company or any corporation with or into which the Company may be consolidated or merged, and the Executive, his heirs, executors,
administrators and legal representatives, provided that the obligations of the Executive hereunder may not be delegated. 
  

	7.	OTHER AGREEMENTS 

 The Executive
represents that the execution and performance of this Agreement will not result in a breach of any of the terms and conditions of any employment or other agreement between the Executive and any third party. 

Provided that the Company duly performs all of its obligations (if any) arising by virtue of a termination of employment of the
Executive, the Executive will not publicly disparage the Company or its officers, directors, employees or agents and will refrain from any action which could reasonably be expected to cause material adverse public relations or embarrassment to the
Company or to any of such persons. Similarly, the Company (including its officers, directors, employees and agents) will not disparage the Executive and will refrain from any action which could reasonably be expected to result in embarrassment to
the Executive or to materially and adversely affect his opportunities for employment. The preceding two (2) sentences shall not apply to disclosures required by applicable law, regulation or order of a court or governmental agency. 

The Company may withhold from any amounts payable under this Agreement all federal, state, local and foreign taxes as may be required to
be withheld pursuant to any applicable law or regulation.

 12Form of General Release

 Exhibit 10.02 
 ATTACHMENT A 
 FORM OF GENERAL RELEASE 

THIS GENERAL RELEASE (this “Agreement”) entered into as of the [•] day of [•] between SOUTHWEST GAS
CORPORATION, a California corporation (the “Company”), and [•] (the “Executive” and, together with the Company, “the parties”). 

The Executive acknowledges that the Executive’s employment with the Company terminated effective [•] (the “Termination
Date”). The Executive further acknowledges that the Executive has received the Executive’s final paycheck, which includes the Executive’s final wages and pay for any accrued but unused vacation or personal days through the
Executive’s last day of employment, less withholdings. The parties acknowledge that except as provided for in this Agreement, all benefits and perquisites of employment ceased as of the Termination Date. 

Further, upon execution without revocation of this Agreement, the Company will provide the Executive with the severance benefits (the
“Severance Benefits”) set forth in and subject to the terms of Section 3 of the Change in Control Agreement entered into and effective as of the [•] day of [•] between the Executive and the Company (the
“Change in Control Agreement”). 
 The Executive understands and agrees that the Executive is not entitled to
any compensation, benefits, remuneration, accruals, contributions, reimbursements, bonus, equity or equity-linked grant, vesting, or vacation or other payments from the Company other than the Severance Benefits, and that any and all payments and
benefits the Executive may receive under this Agreement are subject to all applicable taxes and withholdings. The Executive further understands and agrees that the Executive’s eligibility for any Severance Benefits is subject to the
Executive’s compliance with the terms and conditions of this Agreement and the Change in Control Agreement. 
 In exchange
for Severance Benefits, which the Executive acknowledges exceed any amounts to which the Executive otherwise may be entitled under the Company’s policies and practices or applicable law, the Executive and the Executive’s representatives
completely release from, and agree to not file, cause to be filed or pursue against, the Company, its affiliated, related, parent or subsidiary companies, and its present and former directors, officers, employees and agents (the “Released
Parties”) all claims of any kind, known and unknown, which the Executive may now have or have ever had against any of them, or arising out of the Executive’s relationship with any of them, including all claims for compensation and
bonuses, attorneys’ fees, and all claims arising from the Executive’s employment with the Company or the termination of the Executive’s employment, whether based on contract, tort, statute, local ordinance, regulation or any
comparable law in any jurisdiction (the “Released Claims”). By way of example and not limitation, the Released Claims shall include any claims arising under Title VII of the Civil Rights Act of 1964, as amended, the Americans with
Disabilities Act of 1990, as amended, the Age Discrimination in Employment Act of 1967, as amended (the “ADEA”), the federal Worker Adjustment Retraining Notification Act of 1988, as amended (“WARN Act”) (or
any comparable state law in any jurisdiction). Finally, the Executive agrees that with the exception of the Executive’s final wages and pay for any accrued but unused vacation or personal days through the Executive’s last day of
employment, less withholdings, all other payments and benefits referenced in this Agreement are in excess of any amounts to which the Executive otherwise is legally entitled, and that these amounts shall be offset against any

  
 1 

 
WARN Act (or other similar federal, state or local) notice or pay in lieu of notice obligation, if any, that the Company may be found to have in the future. 

[Delete this paragraph if the Executive is under 40 years of age. Use 21 day review period if only one employee is being terminated and
offered consideration in exchange for signing a release and that employee is 40 or older. Use 45 day review period and include Attachment 1 only if one or more employees are being terminated and offered consideration in exchange for signing a
release at least one of whom is 40 or older. Regardless of how many employees are being terminated and offered consideration in exchange for signing a release, only those employees who are 40 or older have a legal right to a 21 or 45 day review
period and/or Attachment 1.] In this paragraph, the Executive is provided with specific information required under the ADEA. The Executive acknowledges that the Executive has received and reviewed any and all information required, if any, by the
ADEA or the Older Workers Benefit Protection Act of 1990, as amended, pertaining to the Executive’s termination from the Company[, including the information in Attachment 1]. The Executive agrees that the Executive’s release of claims in
this Agreement includes a knowing and voluntary waiver of any rights the Executive may have under the ADEA. The Executive acknowledges that the Executive has been given an opportunity to consider for [twenty-one (21)] OR [forty-five (45)]
days the terms of this Agreement, although the Executive may sign this Agreement beforehand, and that the Executive is advised by the Company to consult with an attorney. The Executive further understands that the Executive can revoke the
Executive’s waiver of ADEA claims within seven (7) days of signing it, but that the Executive will not be eligible for any Severance Benefits if the Executive revokes the Executive’s waiver. Revocation must be made by delivering a
written notice of revocation to: 
 Southwest Gas Corporation 

5241 Spring Mountain Road 
 Las Vegas, Nevada 89150 
 Attn: General Counsel 

The Executive acknowledges and agrees that for the revocation to be effective, the written notice must be received no later than the
close of business (5:00 p.m. P.S.T.) on the seventh
(7th) day after the Executive signs this Agreement.
This Agreement will become effective and enforceable on the eighth (8th) day following the Executive’s execution of this Agreement, provided the Executive has not exercised the Executive’s right to revoke this Agreement. The Executive
further agrees that any change to this Agreement, whether material or immaterial, will not restart the [twenty-one (21)] OR [forty-five (45)] day review period. 
 Notwithstanding the foregoing, the parties acknowledge and agree that the Executive is not waiving or being required to waive any right that cannot be waived as a matter of law, including the right to
file a charge with or participate in an investigation by a governmental administrative agency. 
 The Executive further agrees
to maintain this Agreement and its contents in the strictest confidence and agrees that the Executive will not disclose the terms of this Agreement to any third party (other than the Executive’s legal and financial advisors) without the prior
written consent of the Company, unless otherwise required by law. The Executive also agrees that the Executive will not make or publish, either orally or in writing, any disparaging statement regarding any Released Parties. The parties further agree
that the Executive will refer any third 

  
 2 

 
party reference requests to [•], who will respond by confirming dates of employment and last position held only. 
 The Executive agrees not to disclose any confidential or proprietary information or know-how belonging to the Company or acquired by the Executive during the Executive’s employment with the Company.

 The Executive and the Company further agree that the sole remedy for any and all disputes arising out of or based on the
terms, interpretation, application, or alleged breach of this Agreement, including any of the Released Claims, shall be resolved in an arbitration proceeding pursuant to Section 5 of the Change in Control Agreement. 

The entire understanding and agreement between the parties has been incorporated into this Agreement, and this Agreement supersedes all
other agreements, negotiations, and understandings between the Executive and the Company with respect to the subject matter hereof. This Agreement may not be amended orally, but only by an agreement in writing signed by both parties. This Agreement
shall be governed by and interpreted in accordance with the laws of the State of Nevada. It is intended by the parties that this Agreement be interpreted in accordance with its fair and simple meaning, not for or against either of the parties, and
neither of the parties shall be deemed to be the drafter of this Agreement. This Agreement may be executed simultaneously in two (2) or more counterparts, each of which shall be deemed an original, but all of which shall together constitute one
(1) and the same Agreement. If any portion or provision of this Agreement is determined by arbitration or by a court of competent jurisdiction to be invalid, illegal or unenforceable, the remaining portions or provisions hereof shall not be
affected. 
 Finally, by the Executive’s signature below, the Executive acknowledges each of the following: (a) that
the Executive has read this Agreement or has been afforded every opportunity to do so; (b) that the Executive is fully aware of the Agreement’s contents and legal effect; and (c) that the Executive has chosen to enter into this
Agreement freely, without coercion and based upon the Executive’s own judgment and not in reliance upon any promises made by the Company other than those contained in this Agreement. 

IN WITNESS WHEREOF, this Agreement has been executed by the parties hereto as of the date first written above.
