Dear Xxxx:

This letter (this “Agreement”) confirms the terms of your engagement to provide consulting services to Centuri Holdings, Inc. (“Holdings”) and Centuri Group, Inc. (the “Group” and, together with Holdings, the “Company”), effective as of July 1, 2024 (the “Effective Date”).

1. Consulting Services. During the Term (defined below), you shall provide consulting services to the Group and its Affiliates (defined below). Specifically, from the Effective Date through July 31, 2024 (or such earlier date as the current Chief Executive Officer ceases serving in such role), you will serve as Senior Advisor to the Chief Executive Officer and shall have duties, responsibilities and authorities specified by the Chief Executive Officer and the Board of Directors of Holdings (the “Board”). For the remainder of the Term (defined below), you will serve as Interim President and Chief Executive Officer of Holdings and the Group, and shall have the duties, responsibilities and authorities customary for such a position in an organization of the size and nature of the Company, subject to the ability of the Board to expand, change or limit such duties, responsibilities and authorities in the Board’s sole discretion (all services during the Term, the “Services”). You shall report directly to the Board, and you shall devote your best efforts and full business time and attention (except for permitted vacation periods and reasonable periods of illness or other incapacity) to the business and affairs of the Company and their Affiliates (defined below). This Agreement and your Services will continue until terminated in accordance with the provisions of Section 3 or Section 6 below, as applicable. Your Independent Contractor Consulting Agreement, by and between you and Centuri Construction Group, Inc., dated April 1, 2019, as amended, and all obligations thereunder, shall terminate in their entirety effective as of June 30, 2024, and are of no further force or effect.

2. Relationship of Parties. You and the Company expressly agree that in providing Services to the Company under this Agreement you will be an independent contractor and will not be an employee of the Company or any of their Affiliates (the “Consulting Relationship”). You and the Company further agree that you will provide Services hereunder independently and will not receive training or direction from the Company or any of their Affiliates, other than as to the goals to be achieved through the provision of such Services contemplated in this Agreement. For purposes of this Agreement, “Affiliates” means all entities directly or indirectly controlling, controlled by or under common control with Holdings or Group, as applicable.

3. Term. The term of this Agreement shall commence on the Effective Date and shall continue for an initial term of six months thereafter (the “Initial Term”). If, as of the last day of the Initial Term, a successor Chief Executive Officer has not been appointed by the Board and this Agreement has not been terminated pursuant to Section 6, the term of this Agreement may be extended for successive one-month periods thereafter by written agreement between you and the Company unless and until a successive Chief Executive Officer is appointed by the Board (the “Extended Term”, and together with the Initial Term, the “Term”). The Initial Term and any Extended Term may expire before the final day thereof pursuant to Section 6.

4. Consulting Fees. In exchange for the Services that you provide to the Company under this Agreement, the Company will provide you with the following:

Monthly Stipend. During the Term, you will be paid a consulting fee at the monthly rate of $275,000 in arrears (the “Consulting Fees”). You acknowledge that you will receive an Internal Revenue Service Form 1099 from the Company, and that you shall be solely responsible for all federal, state, and local taxes, in accordance with Section 5. For the avoidance of doubt, you shall not be entitled to any additional cash, bonus or other cash-based incentives, and your entitlement to Consulting Fees is conditioned upon your provision of full-time Services in accordance with the terms of this Agreement even if a successor Chief Executive Officer is named prior to the completion of the Term.

Expenses. You agree to present appropriate documentation for all reasonable business expenses incurred in connection with your performance of the Services in accordance with the Company’s expense reimbursement policy.

Equity Incentive Award. On or promptly following the Effective Date, subject to the approval by the Board (or the Compensation Committee thereof), Holdings will grant to you an award of time-based restricted stock units valued at $500,000, with such value determined by the closing stock price of Holdings’ common stock on July 1, 2024 (the “RSUs”). The RSUs will vest in full on the one-year anniversary of the Effective Date and, except as otherwise set forth in the form of award agreement attached as Exhibit A to this Agreement, shall be subject to your continued provision of Services through the vesting date.

5. Taxes and Benefits.

Taxes and Benefits. You acknowledge and agree that, as an independent contractor, all amounts paid in respect of your Services shall represent fees for services as an independent contractor and you shall bear all tax-related and other such liability as may result from the provision of Services hereunder, including remittances for any personal taxes, self-employment taxes, insurance premiums or any other duties, levies or taxes. You further agree that, as an independent contractor, you shall not be entitled to nor participate in any Company employee benefit plans nor receive any benefits thereunder, except for holiday and vacation benefits as described below.

Holidays and Vacation. You will be eligible for paid vacation time and holidays in accordance with the Company’s policies for executive officers, as such policies may exist from time to time, during the Term. Pursuant to Company policies, vacation time will not be accrued or paid upon termination.

6. Termination. Pursuant to Section 3, the Consulting Relationship hereunder will continue for the Term, provided, however, that either you or the Company may terminate the Term and the Consulting Relationship at any time upon 30 days’ advance written notice to the other party. Upon termination of the Term and the Consulting Relationship for any reason, the Company shall provide you payment for any earned but unpaid Consulting Fees through the date of termination and payment or reimbursement of expenses that are satisfactorily documented and substantiated in accordance with Section 4 above, in each case solely to the extent not already paid. Additionally, if the Company terminates the Term and the Consulting Relationship without Cause (as defined below) and not due to your death or Disability (defined below) during the Initial Term (including any such termination in connection with the appointment of a successor Chief Executive Officer), you will continue to receive the Consulting Fees through the end of the Initial Term, subject to your execution and nonrevocation of a release in favor of the Company in a form to be provided by the Company. For the avoidance of doubt, if the Term and the Consulting Relationship terminate for any reason other than as set forth in the preceding sentence, you will not be entitled to any Consulting Fees other than for earned but unpaid Consulting Fees through the date of termination.

For purposes of this Agreement, “Cause” shall mean: (a) negligence in the performance of, intentional nonperformance of, or inattention to your material duties and responsibilities hereunder, any of which continue for 30 business days after receipt of written notice of need to cure the same; (b) your willful dishonesty, fraud or material misconduct with respect to the business or affairs of the Company; (c) your violation of any of the Company’s policies or procedures, which violation is not cured by you within 30 business days after you have been given written notice thereof; (d) your conviction of, a plea of nolo contendere to, or a guilty plea or a confession by you to an act of fraud, misappropriation or embezzlement or any crime punishable as a felony or any other crime that involves moral turpitude; (e) your use of illegal substances or habitual drunkenness that interferes with your ability to discharge your duties, responsibilities, or obligations to the Company, as determined in the Board’s sole discretion; or (f) the breach by you of a material provision of this offer letter if you do not cure such breach within 30 business days after you have been given written notice thereof.

For purposes of this Agreement, “Disability” means that you are unable to engage in any substantial gainful activity by reason of a physical or mental impairment that is expected to result in death or to last six months or more or you become eligible for long term disability payments under the Company’s applicable long term disability program.

Units		Vesting Date
100%

1. Grant of Units. The Company hereby grants the Participant an Award of Restricted Stock Units covering the number of Shares set forth above (the “Units”) under the Plan, subject to the terms and conditions of the Plan and this Award Agreement. The Units are granted in consideration of the services to be rendered by the Participant to the Company or a Related Entity. Each Unit represents the right to receive one Share (or the cash equivalent thereof) if the Units vest. The Units shall be credited to a separate account maintained for the Participant on the books and records of the Company. All amounts credited to the Participant’s account shall continue for all purposes to be part of the general assets of the Company. Unless and until such time as Shares are issued in settlement of the vested Units, the Participant shall not have any of the rights of a stockholder of the Company with respect to any of the Shares, including any voting rights or rights with respect to dividends paid on the Shares. The Units or the rights relating thereto may not be sold, transferred, pledged, attached, assigned, or otherwise alienated or encumbered by the Participant in any manner, whether voluntarily, by operation of law, or otherwise. Any attempt to assign, alienate, pledge, attach, sell or otherwise transfer or encumber the Units or the rights relating thereto shall be wholly ineffective.

1. Vesting of Units. Except as otherwise provided herein, the Units will vest on the Vesting Date, subject to the Participant’s Service through the Vesting Date.

2. Forfeiture of Units. Except as provided otherwise in Section 4 below, unvested Units shall be forfeited upon a termination of the Participant’s Service. The Participant agrees to execute such documentation that may be reasonably requested by the Company or a Related Entity in connection with such forfeiture. All rights of the Participant with respect to any forfeited Units shall cease and terminate upon forfeiture of such Units, without any further obligation on the part of the Company or a Related Entity.

3. Termination of Service.

(a) Death, Disability, Involuntary Termination Without Cause or Non-Extension of Consulting Agreement Term. If, prior to the Vesting Date, the Participant’s Service is terminated (i) due to the Participant’s death, (ii) by the Company due to the Participant incurring a Disability, (iii) by the Company without Cause (for the avoidance of doubt, including if due to the appointment of a successor Chief Executive Officer), or (iv) due to the expiration of the Consulting Agreement term before the appointment of a successor Chief Executive Officer if such expiration is due to the Company not agreeing to extend the term of the Consulting Agreement, the Units shall become fully vested as of the date of such termination. For purposes of this Award Agreement, the terms “Disability” and “Cause” shall have the meanings as set forth in the Consulting Agreement.

(b) Other Terminations. For the avoidance of doubt, if the Participant’s Service is terminated for any reason other than those set forth in Section 4(a) prior to the Vesting Date, then any unvested Units shall be forfeited and the Participant’s rights with respect to any unvested Units shall cease and terminate, without any further obligation on the part of the Company or a Related Entity.

4. Dividend Equivalent Rights. From the Date of Grant and until the Units are settled pursuant to Section 6, the Participant’s account will be credited with Dividend Equivalent Rights (without interest and earnings) at the same time, in the same form, and in equivalent amounts as dividends that are payable from time to time on Shares. Any such Dividend Equivalent Rights shall be valued as of the date on which they are credited to the Participant and, unless determined otherwise by the Company, reallocated to additional Units. Such additional Units may also earn Dividend Equivalent Rights and shall vest in accordance with the Vesting Schedule as if such Units had been issued on the Date of Grant. Dividend Equivalent Rights shall be subject to the same vesting and forfeiture restrictions as the Units to which they are attributable.

5. Settlement of Units.

(a) Settlement After Outside Date. If the Units vest after the date of the distribution of Shares by Southwest Gas Holdings, Inc. (“Parent”) to its shareholders in a transaction intended to be governed by Section 355 of the Code (or such date that Parent notifies the Company that no such distribution will occur) (the “Outside Date”), as soon as administratively possible, as determined solely by the Company, but within 60 days following the applicable Vesting Date (which, for clarity, would be the earlier of the date of termination described in Section 4 or the applicable Vesting Date), the Participant shall receive a number of Shares equal to the number of Units that vest on the applicable Vesting Date (including any vested Units attributable to Dividend Equivalent Rights), and a cash payment in respect of any Dividend Equivalent Rights paid in cash. Upon a distribution of Shares as provided herein, the Company shall cause the Shares then being distributed to be registered in the Participant’s name. From and after the date of receipt of such distribution, the Participant or the Participant’s legal representatives, beneficiaries or heirs, as the case may be, shall have full rights of transfer or resale with respect to such Shares subject to applicable Company policies and state and federal regulations.

(b) Settlement Prior to Outside Date. If the Units vest on or prior to the Outside Date, the Units shall be settled in cash rather than Shares unless Parent has provided written consent that the Units may be settled in Shares pursuant to Section 6(a), with the amount of cash being equal to the product of the Fair Market Value of a Share on the applicable Vesting Date, multiplied by the number of Units that vest on the applicable Vesting Date and with such payment occurring on the same date that Shares would have otherwise been issued.

6. Administration. This Award Agreement and the rights of the Participant hereunder are subject to all the terms and conditions of the Plan. Any inconsistency between this Award Agreement and the Plan shall be resolved in favor of the Plan.

7. Holding Requirements. Due to the Participant’s temporary role, the Participant shall not be subject to the Company’s Stock Ownership Guidelines and, accordingly, any Shares received pursuant to this Award Agreement will not be subject to any holding requirements thereunder.

8. Taxes. As an independent contractor, the Participant shall be fully responsible for, and shall bear, all taxes that may be imposed on the Participant with respect to the Units, including, without limitation, as a result of the receipt of Shares or Dividend Equivalent Rights. The Participant acknowledges that the Company will not withhold or deposit taxes for or on behalf of the Participant.

9. Section 409A. This Award Agreement is intended to comply with Section 409A or an exemption thereunder and shall be construed and interpreted in a manner that is consistent with the requirements for avoiding additional taxes or penalties under Section 409A. Any distribution pursuant to this Award Agreement that is subject to the requirements of Section 409A may only be made in a manner and upon an event permitted by Section 409A. Payments upon termination of Service may only be made upon a “separation from service” under Section 409A. Notwithstanding the foregoing, neither the Company nor any Related Entity makes any representations that the payments and benefits provided under this Award Agreement comply with Section 409A and in no event shall the Company or any Related Entity be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by the Participant on account of non-compliance with Section 409A. Notwithstanding anything to the contrary herein, if the Participant is a “specified employee” as defined in Section 409A, in the case of a distribution of Shares due to any termination, other than due to death, to the extent required to avoid incurring taxes under Section 409A, the distribution of Shares (and any Dividend Equivalent Rights) in respect of the vested Units shall not occur until the date which is six months following the Termination Date (or, if earlier, upon the death of the Participant). Upon a distribution of Shares as provided herein, the Company shall cause the Shares then being distributed to be registered in the Participant’s name. From and after the date of receipt of such distribution, the Participant or the Participant’s legal representatives, beneficiaries or heirs, as the case may be, shall have full rights of transfer or resale with respect to such Shares subject to applicable Company policies and state and federal regulations.

Accordingly, all such restrictive covenants contained in the Consulting Agreement and such other agreements are hereby deemed incorporated fully herein by reference as if set forth herein. Accordingly, all such restrictive covenants contained herein, and such other agreements, are hereby deemed incorporated fully herein by reference as if set forth herein.
