Statement of Purpose

WHEREAS, the Company, the Lenders party thereto, the other Credit Parties party thereto and the Administrative Agent are parties to the Second Amended and Restated Credit Agreement dated as of August 27, 2021 (as amended hereby and as further amended, restated, extended, supplemented or otherwise modified from time to time, the “Credit Agreement” and the Credit Agreement prior to giving effect to this Amendment being referred to as the “Existing Credit Agreement”), pursuant to which the Lenders have extended certain credit facilities to the Borrowers.

WHEREAS, the Company and the Administrative Agent have elected to make an Early Opt-in Election to transition from LIBOR to Term SOFR solely with respect to the Initial Term Loan, pursuant to the terms of the Existing Credit Agreement.

WHEREAS, the Company has requested that the Administrative Agent and the Lenders agree to amend the Existing Credit Agreement as more specifically set forth herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

(b) Exhibit D (Form of Notice of Prepayment) and Exhibit E (Form of Notice of Conversion/Continuation) to the Existing Credit Agreement are each hereby amended and restated in its entirety as set forth as Annex B hereto.

3.Early Opt-in Election. Pursuant to Section 5.8(c)(i) of the Existing Credit Agreement, the Company and the Administrative Agent have made an Early Opt-in Election to replace the LIBOR Rate with Term SOFR solely with respect to Initial Term Loans. On and after the Effective Date, all outstanding Initial Term Loans that are LIBOR Rate Loans denominated in Dollars shall continue as LIBOR Rate Loans under the Credit Agreement (and, notwithstanding anything in this Amendment including Annex A hereto to the contrary, subject to the terms and conditions and applicable interest rate terms (including breakage) with respect to LIBOR Rate Loans under the Existing Credit Agreement)

174327674_3

solely for the remainder of the Interest Periods applicable thereto immediately prior to the effectiveness of this Amendment; it being understood that such LIBOR Rate Loans and Interest Periods are not being renewed or extended as a result of this Amendment and, upon the expiration or earlier termination of such Interest Periods, such LIBOR Rate Loans shall be (i) repaid or (ii) converted to Base Rate Loans or SOFR Loans (in each case, as defined in the Credit Agreement) as the Borrowers may elect (which election in the case of clause (ii) shall be made in accordance with the notice requirements set forth in Section 5.2 of the Credit Agreement as though the Borrowers were requesting a borrowing to be made on the effective date of such conversion). This Amendment shall constitute notice to the Lenders of an Early Opt-In Election.

4.Conditions to Effectiveness.

5.Representations and Warranties. Each Credit Party represents and warrants as follows:

(a)Each Credit Party has the right, power, and authority and has taken all necessary corporate or other action to authorize the execution, delivery and performance of this Amendment. This Amendment constitutes a legal, valid and binding obligation of such Credit Party, enforceable against each Credit Party that is party hereto in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

(b)The execution, delivery and performance by each Credit Party of this Amendment and the transactions contemplated hereby do not and will not, by the passage of time, the giving of notice or otherwise, (i) require any Governmental Approval or violate any Applicable Law relating to any Credit Party or any Subsidiary thereof where the failure to obtain such Governmental Approval or such violation could reasonably be expected to have a Material Adverse Effect, (ii) conflict with, result in a breach of or constitute a default under the articles of incorporation, bylaws or other organizational documents of any Credit Party or any Subsidiary thereof, (iii) conflict with, result in a breach of or constitute a default under any indenture, agreement or other instrument to which such Person is a party or by which any of its properties may be bound or any Governmental Approval relating to such Person, which could, individually or in the aggregate, reasonably be expected to have a Material Adverse

174327674_3

Effect, (iv) result in or require the creation or imposition of any Lien upon or with respect to any property now owned or hereafter acquired by such Person other than Permitted Liens or (v) require any consent or authorization of, filing with, or other act in respect of, an arbitrator or Governmental Authority and no consent of any other Person is required in connection with the execution, delivery, performance, validity or enforceability of this Amendment other than consents, authorizations, filings or other acts or consents for which the failure to obtain or make could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(c)After giving effect to this Amendment, the representations and warranties contained in each of the Loan Documents are true and correct in all material respects, except for any representation and warranty that is qualified by materiality or reference to Material Adverse Effect, which such representation and warranty are true and correct in all respects, on and as of the date hereof as though made on and as of such date (other than any such representations or warranties that, by their terms, refer to a specific date, in which case as of such specific date).

(d)No Default or Event of Default shall exist after giving effect to this Amendment.

6.Limited Effect. Except as expressly provided herein, the Credit Agreement and the other Loan Documents shall remain unmodified and in full force and effect. This Amendment shall not be deemed (a) to be a waiver of, consent to, or a modification or amendment of any other term or condition of the Credit Agreement or any other Loan Document, (b) to prejudice any right or rights which the Administrative Agent or the Lenders may now have or may have in the future under or in connection with the Credit Agreement or the other Loan Documents or any of the instruments or agreements referred to therein, as the same may be amended, restated, supplemented or modified from time to time, (c) to be a commitment or any other undertaking or expression of any willingness to engage in any further discussion with the Credit Parties or any of their respective Subsidiaries or any other Person with respect to any other waiver, amendment, modification or any other change to the Credit Agreement or the Loan Documents or any rights or remedies arising in favor of the Lenders or the Administrative Agent, or any of them, under or with respect to any such documents or (d) to be a waiver of, or consent to, or a modification or amendment of, any other term or condition of any other agreement by and among the Credit Parties, on the one hand, and the Administrative Agent or any other Lender, on the other hand. References in the Credit Agreement to “this Agreement” (and indirect references such as “hereunder”, “hereby”, “herein”, “hereof” or other words of like import) and in any other Loan Document to the “Credit Agreement” shall be deemed to be references to the Credit Agreement as modified hereby. Without limiting the generality of the foregoing, the execution and delivery of this Amendment (including the annexes hereto) shall not constitute a novation of any indebtedness or other obligations owing to the Lenders or the Administrative Agent under the Credit Agreement based on facts or events occurring or existing prior to the execution and delivery of this Amendment.

7.Reaffirmation. By its execution hereof, each Credit Party (a) consents to this Amendment and agrees that the transactions contemplated by this Amendment shall not limit or diminish the obligations of such Person, or release such Person from any obligations, under any of the Loan Documents to which it is a party, (b) confirms and reaffirms its obligations under each of the Loan Documents to which it is a party and (c) agrees that each of the Loan Documents to which it is a party remain in full force and effect and are hereby ratified and confirmed.

8.Execution in Counterparts.

Delivery of an executed counterpart of a signature page of this Amendment by facsimile or in electronic (i.e., “pdf” or “tif”) format shall be effective as delivery of a manually executed counterpart of this Amendment. The execution and delivery of this Amendment shall be deemed to include Electronic Signatures on electronic platforms approved by the Administrative Agent, which shall be of the same legal effect, validity or enforceability as delivery of a manually executed signature, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; provided that, upon the request of any party hereto, such Electronic Signature shall be promptly followed by the original thereof

10.Entire Agreement. This Amendment and the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent and/or the Lead Arrangers, constitute the entire agreement among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof.

SECTION 1.11 Rates. The interest rate on LIBOR Rate Loans and Base Rate Loans (when determined by reference to clause (c) of the definition of Base Rate) may be determined by reference to LIBOR, which is derived from the London interbank offered rate. The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. On March 5, 2021, ICE Benchmark Administration (“IBA”), the administrator of the London interbank offered rate, and the Financial Conduct Authority (the “FCA”), the regulatory supervisor of IBA, announced in public statements (the “Announcements”) that the final publication or representativeness date for the London interbank offered rate for Dollars for: (a) 1-week and 2-month tenor settings will be December 31, 2021 and (b) overnight, 1-month, 3-month, 6-month and 12-month tenor settings will be June 30, 2023. No successor administrator for IBA was identified in such Announcements. As a result, it is possible that commencing immediately after such dates, the London interbank offered rate for such tenors may no longer be available or may no longer be deemed a representative reference rate upon which to determine the interest rate on LIBOR Rate Loans or Base Rate Loans (when determined by reference to clause (c) of the definition of Base Rate). There is no assurance that the dates set forth in the Announcements will not change or that IBA or the FCA will not take further action that could impact the availability, composition or characteristics of any London interbank offered rate. Public and private sector industry initiatives have been and continue, as of the date hereof, to be underway to implement new or alternative reference rates to be used in place of the London interbank offered rate. In the event that the London interbank offered rate or any other then-current Benchmark is no longer available or in certain other circumstances set forth in Section 5.8(c), such Section 5.8(c) provides a mechanism for determining an alternative rate of interest. The Administrative Agent will notify Centuri, pursuant to Section 5.8(c), of any change to the reference rate upon which the interest rate on LIBOR Rate Loans and Base Rate Loans (when determined by reference to clause (c) of the definition of Base Rate) is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, (ia) the continuation of, administration of, submission of, calculation of or any other matter related to the Term SOFR Reference Rate, Adjusted TermsTerm SOFR, or Term SOFR, the London interbank offered rate or other rates in any xxxxxx any component definition thereof or rates referred to in the definition thereof, or with respect to any alternative, successor or replacement rate thereto (including any then-current Benchmark or any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement), as it may or may not be adjusted pursuant to Section 5.8(c), will be similar to, or produce the same value or economic equivalence of, LIBOR or any other Benchmark, or have the same volume or liquidity as did, the Term SOFR Reference Rate, Adjusted Term SOFR, Term SOFR or the London interbank offered rate or any other Benchmark prior to its

lvi

165457743_4174358596_2

discontinuance or unavailability, or (iib) the effect, implementation or composition of any Benchmark Replacement Conforming Changes. The Administrative Agent and its Affiliates or other related entities may engage in transactions that affect the calculation of the Term SOFR Reference Rate, Adjusted Term SOFR, Term SOFR, any other Benchmark or any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto and such transactions may be adverse to the Borrowers. The Administrative Agent may select information sources or services in its reasonable discretion to ascertain the Term SOFR Reference Rate, Adjusted Term SOFR, or Term SOFR, or any other Benchmark, any component definition thereof or rates referencedreferred to in the definition thereof, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrowers, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service.

SECTION 1.12 Limited Condition Acquisitions. In the event that Centuri notifies the Administrative Agent in writing that any proposed Acquisition is a Limited Condition Acquisition and that Centuri wishes to test the conditions to such Acquisition and any Incremental Term Loan or Incremental Equivalent Indebtedness that is to be used to finance such Acquisition in accordance with this Section 1.12, then, so long as agreed to by the Administrative Agent and the lenders providing such Incremental Term Loan or such Incremental Equivalent Indebtedness, the following provisions shall apply:

(i)any condition to such Limited Condition Acquisition, such Incremental Term Loan or such Incremental Equivalent Indebtedness that requires that no Default or Event of Default shall have occurred and be continuing at the time of such Limited Condition Acquisition or the incurrence of such Incremental Term Loan or Incremental Equivalent Indebtedness, shall be satisfied if (i) no Default or Event of Default shall have occurred and be continuing at the time of the execution of the definitive purchase agreement, merger agreement or other acquisition agreement governing such Limited Condition Acquisition (the “LCA Test Date”) and (ii) no Event of Default under any of Section 10.1(a), 10.1(b), 10.1(i) or 10.1(j) shall have occurred and be continuing both immediately before and immediately after giving effect to such Limited Condition Acquisition and any Indebtedness incurred in connection therewith (including any such additional Incremental Term Loan or Incremental Equivalent Indebtedness);

(ii)any condition to such Limited Condition Acquisition, such Incremental Term Loan or such Incremental Equivalent Indebtedness that the representations and warranties in this Agreement and the other Loan Documents shall be true and correct at the time of consummation of such Limited Condition Acquisition or the incurrence of such Incremental Term Loan or Incremental Equivalent Indebtedness shall be deemed satisfied if (i) all representations and warranties in this Agreement and the other Loan Documents are true and correct in all material respects (except for any representation and warranty that is qualified by materiality or reference to Material Adverse Effect, which such representation and warranty shall be true and correct in all respects) as of the LCA Test Date, or if such representation speaks as of an earlier date, as of such earlier date and (ii) as of the date of consummation of such Limited Condition Acquisition, (A) the representations and warranties under the relevant definitive agreement governing such Limited Condition Acquisition as are material to the lenders providing such Incremental Term Loan or Incremental Equivalent Indebtedness shall be true and correct, but only to the extent that Centuri or its applicable Subsidiary has the right to terminate its obligations under such agreement or otherwise decline to close such Limited Condition Acquisition as a result of a breach of such representations and warranties or the failure of those representations and warranties to be true and correct and (B) certain of the representations and warranties in this Agreement and the other Loan Documents which are customary for similar “funds certain” financings and required by the lenders providing such Incremental Term Loan or Incremental Equivalent Indebtedness shall be true and correct in all material respects (except for any representation and warranty that is qualified by materiality or reference to Material Adverse Effect, which such representation and warranty shall be true and correct in all respects);

(iii)any financial ratio test or condition to be tested in connection with such Limited Condition Acquisition and the availability of such Incremental Term Loan or Incremental Equivalent Indebtedness will be tested as of the LCA Test Date, in each case, after giving effect to the relevant Limited Condition Acquisition and related incurrence of Incremental Term Loan or Incremental Equivalent Indebtedness, on a

lvii

165457743_4174358596_2

Pro Forma Basis where applicable, and, for the avoidance of doubt, (i) such ratios and baskets shall not be tested at the time of consummation of such Limited Condition Acquisition and (ii) if any of such ratios are exceeded or conditions are not met following the LCA Test Date, but prior to the closing of such Limited Condition Acquisition, as a result of fluctuations in such ratio or amount (including due to fluctuations in Consolidated EBITDA of Centuri or the Person subject to such Limited Condition Acquisition), at or prior to the consummation of the relevant transaction or action, such ratios will not be deemed to have been exceeded and such conditions will not be deemed unmet as a result of such fluctuations solely for purposes of determining whether the relevant transaction or action is permitted to be consummated or taken;

(iv)except as provided in the next sentence, in connection with any subsequent calculation of any ratio or basket on or following the relevant LCA Test Date and prior to the earlier of the date on which such Limited Condition Acquisition is consummated and the date that the definitive agreement for such Limited Condition Acquisition is terminated or expires without consummation of such Limited Condition Acquisition, any such ratio or basket shall be calculated on a Pro Forma Basis assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of the applicable Incremental Term Loan, Incremental Equivalent Indebtedness or any other applicable Indebtedness) have been consummated; provided that any calculation of any such ratio or basket under Section 9.6 and Section 9.9 shall be calculated (i) on a Pro Forma Basis assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of the applicable Incremental Term Loan, Incremental Equivalent Indebtedness or any other applicable Indebtedness) have been consummated and (ii) assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of the applicable Incremental Term Loan, Incremental Equivalent Indebtedness or any other applicable Indebtedness) have not been consummated. Notwithstanding the foregoing, any calculation of a ratio in connection with determining the Applicable Margin and determining whether or not the Borrower is in compliance with the financial covenants set forth in Section 9.13 shall, in each case be calculated assuming such Limited Condition Acquisition and other transactions in connection therewith (including the incurrence or assumption of the applicable Incremental Term Loan, Incremental Equivalent Indebtedness or any other applicable Indebtedness to be incurred or assumed in connection with such Acquisition) have not been consummated.

The foregoing provisions shall apply with similar effect during the pendency of multiple Limited Condition Acquisitions such that each of the possible scenarios is separately tested.

SECTION 1.13 Divisions. For all purposes under the Loan Documents, in connection with any division or plan of division under Delaware law (or any comparable event under a different jurisdiction’s laws): (a) if any asset, right, obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized on the first date of its existence by the holders of its Equity Interests at such time.

Each Revolving Credit Lender will immediately transfer to the applicable Swingline Lender, in immediately available funds, the amount of its participation and upon receipt thereof such Swingline Lender will deliver to such Revolving Credit Lender a certificate evidencing such participation dated the date of receipt of such funds and for such amount. Whenever, at any time after the applicable Swingline Lender has received from any Revolving Credit Lender such Revolving Credit Lender’s participating interest in a Swingline Loan, the applicable Swingline Lender receives any payment on account thereof, the applicable Swingline Lender will distribute to such Revolving Credit Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Revolving Credit Lender’s participating interest was outstanding and funded).

A Notice of Prepayment received after 11:00 a.m. shall be deemed received on the next Business Day or US Government Securities Business Day, as applicable. Each such repayment shall be accompanied by any amount required to be paid pursuant to Section 5.9 hereof. Notwithstanding the foregoing, any Notice of Prepayment delivered in connection with any refinancing of all of the Credit Facility with the proceeds of such refinancing or of any incurrence of Indebtedness, may be, if expressly so stated to be, contingent upon the consummation of such refinancing or incurrence and may be revoked by the Borrowers in the event such refinancing is not consummated (provided that the failure of such contingency shall not relieve any Borrower from its obligations in respect thereof under Section 5.9).

(iv)Prepayment of Excess Proceeds. In the event proceeds remain after the prepayments of Term Loan Facility pursuant to Section 4.4(b), the amount of such excess proceeds shall be used on the date of the required prepayment under Section 4.4(b) to prepay the outstanding principal amount of the Revolving Credit Loans, without a corresponding reduction of the Revolving Credit Commitment, with remaining proceeds, if any, refunded to the Borrowers.

(v)Limitation on Prepayment of SOFR Loans. The Borrowers may not prepay any SOFR Loan on any day other than on the last day of the Interest Period applicable thereto unless such prepayment is accompanied by any amount required to be paid pursuant to Section 5.9 hereof.

(vi)Hedge Agreements. No repayment or prepayment of the Loans pursuant to this Section shall affect any of the Borrowers’ obligations under any Hedge Agreement entered into with respect to the Loans.

SECTION 2.5 Permanent Reduction of the Revolving Credit Commitment.

(i)Voluntary Reduction. The Borrowers shall have the right at any time and from time to time, upon at least five (5) Business Days prior irrevocable written notice to the Administrative Agent, to permanently reduce, without premium or penalty, (i) the entire Revolving Credit Commitment at any time or (ii) portions of the Revolving Credit Commitment, from time to time, in an aggregate principal amount not less than $3,000,000 or any whole multiple of $1,000,000 in excess thereof. Any reduction of the Revolving Credit Commitment shall be applied to the Revolving Credit Commitment of each Revolving Credit Lender according to its Revolving Credit Commitment Percentage. All Commitment Fees accrued until the effective date of any termination of the Revolving Credit Commitment shall be paid on the effective date of such termination. No such reduction in the Revolving Credit Commitments shall reduce the Swingline Commitment or the L/C Sublimit (except as set forth in each respective definition). Notwithstanding the foregoing, any notice to reduce the Revolving Credit Commitment to zero delivered in connection with any refinancing of all of the Credit Facility with the proceeds of such refinancing or of any incurrence of Indebtedness, may be, if expressly so stated to be, contingent upon the consummation of such refinancing or incurrence and may be revoked by any Borrower in the event such refinancing is not consummated (provided that the failure of such contingency shall not relieve any Borrower from its obligations in respect thereof under Section 5.9).

lxii

165457743_4174358596_2

(ii)Corresponding Payment. Each permanent reduction permitted pursuant to this Section shall be accompanied by a payment of principal sufficient to reduce the aggregate outstanding Revolving Credit Loans, Swingline Loans and L/C Obligations, as applicable, after such reduction to the Revolving Credit Commitment as so reduced, and if the aggregate amount of all outstanding Letters of Credit exceeds the Revolving Credit Commitment as so reduced, the applicable Borrower shall be required to deposit Cash Collateral in a Cash Collateral account opened by the Administrative Agent in an amount equal to such excess. Such Cash Collateral shall be applied in accordance with Section 10.2(b). Any reduction of the Revolving Credit Commitment to zero shall be accompanied by payment of all outstanding Revolving Credit Loans and Swingline Loans (and furnishing of Cash Collateral satisfactory to the Administrative Agent for all L/C Obligations) and shall result in the termination of the Revolving Credit Commitment and the Swingline Commitment and the Revolving Credit Facility. If the reduction of the Revolving Credit Commitment requires the repayment of any SOFR Loan, such repayment shall be accompanied by any amount required to be paid pursuant to Section 5.9 hereof.

SECTION 2.6 Termination of Revolving Credit Facility. The Revolving Credit Facility and the Revolving Credit Commitments shall terminate on the Revolving Credit Maturity Date (after giving effect to any Extension).

Upon receipt of any Letter of Credit Application, the applicable Issuing Lender shall process such Letter of Credit Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall, subject to Section 3.1 and Article VI, promptly issue the Letter of Credit requested thereby (but in no event shall such Issuing Lender be required to issue any Letter of Credit earlier than three (3) Business Days after its receipt of the Letter of Credit Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by such Issuing Lender and the applicable Borrower. The applicable Issuing Lender shall promptly furnish to the applicable Borrowers and the Administrative Agent a copy of such Letter of Credit and the Administrative Agent shall promptly notify each Revolving Credit Lender of the issuance and upon request by any Lender, furnish to such Revolving Credit Lender a copy of such Letter of Credit and the amount of such Revolving Credit Xxxxxx’s participation therein.

SECTION 3.3 Commissions and Other Charges.

(i)Letter of Credit Commissions. Subject to Section 5.15(a)(iii)(B), Centuri shall pay to the Administrative Agent, for the account of the applicable Issuing Lender and the L/C Participants, a letter of credit commission with respect to each Letter of Credit in the amount equal to the daily amount available to be drawn under such Letters of Credit times 50% of the Applicable Margin with respect to Revolving Credit Loans that are SOFR Loans (determined, in each case, on a per annum basis). Such commission shall be payable quarterly in arrears on the last Business Day of each calendar quarter, on the Revolving Credit Maturity Date and thereafter on demand of the Administrative Agent. The Administrative Agent shall, promptly following its receipt thereof, distribute to the applicable Issuing Lender and the L/C Participants all commissions received pursuant to this Section 3.3 in accordance with their respective Revolving Credit Commitment Percentages.

(ii)Issuance Fee. In addition to the foregoing commission, the applicable Borrower shall pay directly to the applicable Issuing Lender, for its own account, an issuance fee with respect to each Letter of Credit issued by such Xxxxxxx Xxxxxx as set forth in the applicable Fee Letter executed by such Issuing Lender.

In addition to the foregoing fees and commissions, the Borrowers shall pay or reimburse each Issuing Lender for such normal and customary fees, costs, charges and expenses as are incurred or charged by such Issuing Lender in issuing, effecting payment under, amending or otherwise administering any Letter of Credit issued by it.

SECTION 3.4 L/C Participations.

(i)Each Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce each Issuing Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from each Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant’s own account and risk an undivided interest equal to such L/C Participant’s Revolving Credit Commitment Percentage in each Issuing Lender’s obligations and rights under and in respect of each Letter of Credit issued by it hereunder and the amount of each draft paid by such Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with each Issuing Lender that, if a draft is paid under any Letter of Credit issued by such Issuing Lender for which such Issuing Lender is not reimbursed in full by the Borrowers through a Revolving Credit Loan or otherwise in accordance with the terms of this Agreement, such L/C Participant shall pay to such Issuing Lender upon demand at such Issuing Lender’s address for notices specified herein an amount equal to such L/C Participant’s Revolving Credit Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed.

(ii)Upon becoming aware of any amount required to be paid by any L/C Participant to any Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit issued by it, such Issuing Lender shall notify the Administrative Agent of such unreimbursed amount and the Administrative Agent shall notify each L/C Participant (with a copy to the applicable Issuing Lender) of the amount and due date of such required payment and such L/C Participant shall pay to the Administrative Agent (which, in turn shall pay such Issuing Lender) the amount specified on the applicable due date. If any such amount is paid to such Issuing Lender after the date such payment is due, such L/C Participant shall pay to such Issuing Lender on demand, in addition to such amount, the product of (i) such amount, times (ii) the daily average Federal Funds Rate as determined by the Administrative Agent during the period from and including the date such payment is due to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. A certificate of such Issuing Lender with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error. With respect to payment to such Issuing Lender of the unreimbursed amounts described in this Section, if the L/C Participants receive notice that any such payment is due (A) prior to 1:00 p.m. on any Business Day, such payment shall be due that Business Day, and (B) after 1:00 p.m. on any Business Day, such payment shall be due on the following Business Day.

(iii)Whenever, at any time after any Issuing Lender has made payment under any Letter of Credit issued by it and has received from any L/C Participant its Revolving Credit Commitment Percentage of such payment in accordance with this Section, such Issuing Lender receives any payment related to such Letter of Credit (whether directly from the US Borrowers or otherwise), or any payment of interest on account thereof, such Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, that in the event that any such payment received by such Issuing Lender shall be required to be returned by such Issuing Lender, such L/C Participant shall return to such Issuing Lender the portion thereof previously distributed by such Issuing Lender to it.

SECTION 3.5 Reimbursement Obligation of the Borrowers. In the event of any drawing under any Letter of Credit, the applicable Borrower agrees to reimburse (either with the proceeds of a Revolving Credit Loan as provided for in this Section or with funds from other sources), in same day funds, the applicable Issuing Lender on each date on which such Issuing Lender notifies the applicable Borrower of the date and amount of a draft paid by it under any Letter of Credit for the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by such Issuing Lender in connection with such payment. Unless the applicable Borrower shall immediately notify such Issuing Lender that such Borrower

lxv

165457743_4174358596_2

intends to reimburse such Issuing Lender for such drawing from other sources or funds, such Borrower shall be deemed to have timely given a Notice of Borrowing to the Administrative Agent requesting that the Revolving Credit Lenders make a Revolving Credit Loan bearing interest at the Base Rate on the applicable repayment date in the amount of (i) such draft so paid and (ii) any amounts referred to in Section 3.3(c) incurred by such Issuing Lender in connection with such payment, and the Revolving Credit Lenders shall make a Revolving Credit Loan bearing interest at the Base Rate in such amount, the proceeds of which shall be applied to reimburse such Issuing Lender for the amount of the related drawing and such fees and expenses. Each Revolving Credit Lender acknowledges and agrees that its obligation to fund a Revolving Credit Loan in accordance with this Section to reimburse such Issuing Lender for any draft paid under a Letter of Credit issued by it is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Section 2.3(a) or Article VI. If a Borrower has elected to pay the amount of such drawing with funds from other sources and shall fail to reimburse such Issuing Lender as provided above, the unreimbursed amount of such drawing shall bear interest at the rate which would be payable on any outstanding Base Rate Loans which were then overdue from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full.

SECTION 3.6 Obligations Absolute. Each Borrower’s obligations under this Article III (including, without limitation, the Reimbursement Obligation) shall be absolute and unconditional under any and all circumstances and irrespective of any set off, counterclaim or defense to payment such Borrower may have or have had against the applicable Issuing Lender or any beneficiary of a Letter of Credit or any other Person. Each Borrower also agrees that the applicable Issuing Lender and the L/C Participants shall not be responsible for, and such Borrower’s Reimbursement Obligation under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among such Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of such Borrower against any beneficiary of such Letter of Credit or any such transferee. No Issuing Lender shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit issued by it, except for errors or omissions caused by such Issuing Xxxxxx’s gross negligence or willful misconduct, as determined by a court of competent jurisdiction by final nonappealable judgment. Each Borrower agrees that any action taken or omitted by any Issuing Lender under or in connection with any Letter of Credit issued by it or the related drafts or documents, if done in the absence of gross negligence or willful misconduct shall be binding on such Borrower and shall not result in any liability of such Issuing Lender or any L/C Participant to any Borrower. The responsibility of any Issuing Lender to the Borrowers in connection with any draft presented for payment under any Letter of Credit issued to it shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment substantially conforms to the requirements under such Letter of Credit.

SECTION 3.7 Effect of Letter of Credit Application. To the extent that any provision of any Letter of Credit Application related to any Letter of Credit is inconsistent with the provisions of this Agreement, the provisions of this Agreement shall apply and control.

SECTION 3.8 Removal and Resignation of Issuing Lenders.

(i)The Borrowers may at any time remove any Lender from its role as an Issuing Lender hereunder upon not less than thirty (30) days prior notice to such Issuing Lender and the Administrative Agent (or such shorter period of time as may be acceptable to such Issuing Lender and the Administrative Agent).

lxvi

165457743_4174358596_2

Lender hereunder upon not less than five (5) Business Days’ prior notice to Centuri and the Administrative Agent (or such shorter period of time as may be acceptable to Centuri and the Administrative Agent).

(iv)Any removed or resigning Issuing Lender shall retain all the rights, powers, privileges and duties of an Issuing Lender hereunder with respect to all Letters of Credit issued by it that are outstanding as of the effective date of its removal or resignation as an Issuing Lender and all L/C Obligations with respect thereto (including, without limitation, the right to require the Revolving Credit Lenders to take such actions as are required under Section 3.4). Without limiting the foregoing, upon the removal or resignation of a Lender as an Issuing Lender hereunder, the Borrowers may, or at the request of such removed or resigned Issuing Lender the Borrowers shall, use commercially reasonable efforts to, arrange for one or more of the other Issuing Lenders to issue Letters of Credit hereunder in substitution for the Letters of Credit, if any, issued by such removed or resigned Issuing Lender and outstanding at the time of such removal or resignation, or make other arrangements satisfactory to the removed or resigned Issuing Lender to effectively cause another Issuing Lender to assume the obligations of the removed or resigned Issuing Lender with respect to any such Letters of Credit.

SECTION 3.9 Reporting of Letter of Credit Information and L/C Commitment. At any time that there is an Issuing Lender that is not also the financial institution acting as Administrative Agent, then (a) on the last Business Day of each calendar month, (b) on each date that a Letter of Credit is amended, terminated or otherwise expires, (c) on each date that a Letter of Credit is issued or the expiry date of a Letter of Credit is extended, and (d) upon the request of the Administrative Agent, each Issuing Lender (or, in the case of clauses (b), (c) or (d) of this Section, the applicable Issuing Lender) shall deliver to the Administrative Agent a report setting forth in form and detail reasonably satisfactory to the Administrative Agent information (including, without limitation, any reimbursement, Cash Collateral, or termination in respect of Letters of Credit issued by such Issuing Lender) with respect to each Letter of Credit issued by such Issuing Lender that is outstanding hereunder. In addition, each Issuing Lender shall provide notice to the Administrative Agent of its L/C Commitment, or any change thereto, promptly upon it becoming an Issuing Lender or making any change to its L/C Commitment. No failure on the part of any Issuing Lender to provide such information pursuant to this Section 3.9 shall limit the obligations of the Borrowers or any Revolving Credit Lender hereunder with respect to its reimbursement and participation obligations hereunder.

SECTION 3.10 Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Borrower or any Subsidiary or Affiliate thereof described in Section 3.1(a), the applicable Borrower shall be obligated to reimburse, or to cause the applicable Subsidiary or Affiliate to reimburse, the applicable Issuing Lender hereunder for any and all drawings under such Letter of Credit; provided that aggregate face amount of all Letters of Credit issued for the account of such Affiliates of the Borrowers that are not also Subsidiaries of the Borrowers shall not exceed $25,000,000 at any time outstanding. Each Borrower hereby acknowledges that the issuance of Letters of Credit for the account of any of its Subsidiaries or Affiliates inures to the benefit of such Borrower and that such Borrower’s business derives substantial benefits from the businesses of such Subsidiaries and Affiliates.

Each prepayment of the Loans under this Section shall be applied as follows: first, ratably between the Initial Term Loan and any Incremental Term Loans to reduce on a pro rata basis (applied to reduce the remaining scheduled principal installments of the Initial Term Loan and any Incremental Term Loans on a pro rata basis) and (ii) second, to the extent of any excess, to repay the Revolving Credit Loans pursuant

lxix

165457743_4174358596_2

to Section 2.4(d), without a corresponding reduction in the Revolving Credit Commitment. Proceeds of any Refinancing Debt shall be applied solely to prepay each applicable Class of Term Loans and/or Revolving Credit Loans subject to such Refinance. Notwithstanding the foregoing, with respect to any Net Cash Proceeds from any Asset Disposition or Insurance and Condemnation Event, the applicable Borrower may prepay Term Loans and prepay or purchase any Refinancing Notes or Incremental Equivalent Indebtedness that is secured by the Collateral on a pari passu basis (at a purchase price no greater than par plus accrued and unpaid interest), to the extent required thereby, on a pro rata basis in accordance with the respective outstanding principal amounts of the Term Loans and such Refinancing Notes or Incremental Equivalent Indebtedness as of the time of the applicable Asset Disposition or Insurance and Condemnation Event.

Each Term Loan Lender may reject all (but not less than all) of its pro rata share of any mandatory prepayment (except in the case of any prepayment of Term Loans in accordance with Section 4.4(b)(i) with the proceeds of Refinancing Debt) (such declined amounts, the “Declined Proceeds”) of Term Loans required to be made pursuant to Section 4.4(b) by providing written notice to the Administrative Agent no later than 5:00 p.m. one Business Day after the date of such Xxxxxx’s receipt of notice from the Administrative Agent regarding such prepayment.

Any Declined Proceeds remaining after offering such Declined Proceeds to the Lenders in accordance with the terms hereof shall be retained by the Borrowers and used for any purpose not prohibited by this Agreement.

(7)Prepayment of LIBOR Rate Loans, SOFR Loans and CDOR Rate Loans. Each prepayment shall be accompanied by any amount required to be paid pursuant to Section 5.9; provided that, so long as no Default or Event of Default shall have occurred and be continuing, if any prepayment of LIBOR Rate Loans, SOFR Loans or CDOR Rate Loans is required to be made under this Section 4.4(b) prior to the last day of the Interest Period therefor, in lieu of making any payment pursuant to this Section 4.4(b) in respect of any such LIBOR Rate Loan, SOFR Loan or CDOR Rate Loans prior to the last day of the Interest Period therefor, the applicable Borrower may, in its sole discretion, deposit an amount sufficient to make any such prepayment otherwise required to be made thereunder together with accrued interest to the last day of such Interest Period into an account held at, and subject to the sole control of, the Administrative Agent until the last day of such Interest Period, at which time the Administrative Agent shall be authorized (without any further action by or notice to or from the Borrowers or any other Credit Party) to apply such amount to the prepayment of such Term Loans in accordance with this Section 4.4(b). Upon the occurrence and during the continuance of any Default or Event of Default, the Administrative Agent shall also be authorized (without any further action by or notice to or from the Borrowers or any other Credit Party) to apply such amount to the prepayment of the outstanding Term Loans in accordance with the relevant provisions of this Section 4.4(b).

Subject to Section 10.3, (i) immediately upon the occurrence and during the continuance of an Event of Default under Section 10.1(a), (b), (i) or (j), or (ii) at the election of the Required Lenders (or the Administrative Agent at the direction of the Required Lenders), upon the occurrence and during the continuance of any other Event of Default, (A) the Borrowers shall no longer have the option to request LIBOR Rate Loans, SOFR Loans, CDOR Rate Loans, Swingline Loans or Letters of Credit, (B) all outstanding LIBOR Rate Loans shall bear interest at a rate per annum of two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to LIBOR Rate Loans until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Base Rate Loans, (C) all outstanding SOFR Loans shall bear interest at a rate per annum of two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to SOFR Loans until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Base Rate Loans, (DC) all outstanding CDOR Rate Loans shall bear interest at a rate per annum of two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to CDOR Rate Loans until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Canadian Base Rate Loans, (ED) all outstanding Base Rate Loans and other US Obligations arising hereunder or under any other Loan Document shall bear interest at a rate per annum equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable

lxxi

165457743_4174358596_2

to Base Rate Loans or such other US Obligations arising hereunder or under any other Loan Document, (FE) all outstanding Canadian Base Rate Loans and other Canadian Obligations arising hereunder or under any other Loan Document shall bear interest at a rate per annum equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Canadian Base Rate Loans or such other Canadian Obligations arising hereunder or under any other Loan Document, and (GF) all accrued and unpaid interest shall be due and payable on demand of the Administrative Agent. Interest shall continue to accrue on the Obligations after the filing by or against any Borrower of any petition seeking any relief in bankruptcy or under any Debtor Relief Law.

(iii)Interest Payment and Computation.

(1)Interest on (A) each Base Rate Loan and each Canadian Base Rate Loan shall be due and payable in arrears on the last Business Day of each calendar quarter commencing December 31, 2021; (B) each US Swingline Loan and each Canadian Swingline Loan shall be due and payable in arrears on the last Business Day of each calendar quarter commencing December 31, 2021; and (C) each LIBOR Rate Loan, SOFR Loan and CDOR Rate Loan shall be due and payable on the last day of each Interest Period applicable thereto, and if such Interest Period extends over three (3) months, at the end of each three (3) month interval during such Interest Period; provided that (i) in the event of any repayment or prepayment of any SOFR Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (ii) in the event of any conversion of any SOFR Loan prior to the end of the Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. All computations of interest for Base Rate Loans when the Base Rate is determined by the Prime Rate, all computations of interest for Canadian Base Rate Loans and all computations of interest for CDOR Rate Loans shall be made on the basis of a year of 365 or 366 days, as applicable, and actual days elapsed. All other computations of fees and interest provided hereunder shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365/366-day year).

(2)Whenever any amount is payable under this Agreement or any other Loan Document by the Canadian Borrowers as interest or as a fee which requires the calculation of an amount using a percentage per annum, each party to this Agreement acknowledges and agrees that such amount shall be calculated as of the date payment is due without application of the “deemed reinvestment principle” or the “effective yield method” (e.g., when interest is calculated and payable monthly, the rate of interest payable per month is 1/12 of the stated rate of interest per annum).

(3)For the purposes of the Interest Act (Canada) and disclosure under such Act, whenever interest to be paid under this Agreement or any other Loan Document is to be calculated on the basis of a year of 365 days or any other period of time that is less than a calendar year, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent is the rate so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by either 365 or such other period of time, as the case may be.

(iv)Maximum Rate.

(1)In no contingency or event whatsoever shall the aggregate of all amounts deemed interest under this Agreement charged or collected pursuant to the terms of this Agreement exceed the highest rate permissible under any Applicable Law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. In the event that such a court determines that the Lenders have charged or received interest hereunder in excess of the highest applicable rate, the rate in effect hereunder shall automatically be reduced to the maximum rate permitted by Applicable Law and the Lenders shall at the Administrative Agent’s option (A) promptly refund to the applicable Borrowers any interest received by the Lenders in excess of the maximum lawful rate or (B) apply such excess to the principal balance of the US Obligations or the Canadian Obligations, as applicable. It is the intent hereof that the Borrowers not pay or contract to pay, and that neither the Administrative Agent nor any Lender receive or contract to receive, directly or indirectly in any manner whatsoever, interest in excess of that which may be paid by the applicable Borrower under Applicable Law.

lxxii

165457743_4174358596_2

(2)If any provision of this Agreement or of any of the other Loan Documents would obligate the Canadian Borrowers or any other Canadian Credit Party to make any payment of interest or other amount payable to any Lender, in an amount or calculated at a rate which would result in a receipt by such Lender of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)) then, notwithstanding such provisions, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in a receipt by such Lender of interest at a criminal rate, such adjustment to be effected, to the extent necessary, as follows: (A) firstly, by reducing the amount or rate of interest required to be paid to such Lender on Canadian Revolving Credit Loans or Canadian Swingline Loans, as applicable, and (B) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid to such Lender, which would constitute “interest” for purposes of Section 347 of the Criminal Code (Canada). Any amount or rate of interest referred to in this Section 5.1 shall be determined in accordance with generally accepted actuarial practices and principles as an effective annual rate of interest over the term that the applicable Canadian Revolving Credit Loan or Canadian Swingline Loan remains outstanding on the assumption that any charges, fees or expenses that fall within the meaning of “interest” (as defined in the Criminal Code (Canada)) shall, if they relate to a specific period of time, be pro-rated over that period of time and otherwise be pro-rated over the period from the Closing Date to the date set out in clause (a) of the definition of “Revolving Credit Maturity Date” and, in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by Administrative Agent shall be conclusive for the purposes of such determination.

(v)Term SOFR Benchmark Replacement Conforming Changes. In connection with the use or administration of Term SOFR, the Administrative Agent (in consultation with Centuri) will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. The Administrative Agent will promptly notify the US Borrower and the Lenders of the effectiveness of any Benchmark Replacement Conforming Changes in connection with the use or administration of Term SOFR.

SECTION 5.2 Notice and Manner of Conversion or Continuation of Loans. Provided that no Default or Event of Default has occurred and is then continuing:

(i)the US Borrowers shall have the option to (ai) convert at any time all or any portion of any outstanding Term Loans that are Base Rate Loans in a principal amount equal to $3,000,000 or any whole multiple of $500,000 in excess thereof into one or more LIBOR Rate Loans, (b) convert at any time all or any portion of any outstanding Revolving Credit Loans that are Base Rate Loans (other than US Swingline Loans) in a principal amount equal to $3,000,000 or any whole multiple of $500,000 in excess thereof into one or more SOFR Loans, and (cii) upon the expiration of any Interest Period, (iA) convert all or any part of its outstanding LIBOR Rate Loans or SOFR Loans in a principal amount equal to $1,000,000 or a whole multiple of $100,000 in excess thereof into Base Rate Loans (other than Swingline Loans), (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans or (iiiB) continue such SOFR Loans as SOFR Loans; and

(ii)the Canadian Borrowers shall have the option to (ai) convert at any time all or any portion of any outstanding Canadian Base Rate Loans (other than Canadian Swingline Loans) in a principal amount equal to C$1,000,000 or any whole multiple of C$100,000 in excess thereof into one or more CDOR Rate Loans and (bii) upon the expiration of any Interest Period for such CDOR Rate Loans, (iA) convert all or any part of its outstanding CDOR Rate Loans in a principal amount equal to C$1,000,000 or a whole multiple of C$100,000 in excess thereof into Canadian Base Rate Loans (other than Canadian Swingline Loans) or (iiB) continue such CDOR Rate Loans as CDOR Rate Loans.

Whenever any Borrower desires to convert or continue Loans as provided above, such Borrower shall give the Administrative Agent irrevocable prior written notice in the form attached as Exhibit E (a “Notice of Conversion/Continuation”) not later than 11:00 a.m. three (3) Business Days before (or three (3) US Government Securities Business Days before the day of a proposed conversion to or continuation of SOFR Loans or four (4) Business Days before the day of a proposed conversion to or continuation of CDOR Rate Loans) the day on which a proposed conversion or continuation of such Loan is to be effective specifying

lxxiii

165457743_4174358596_2

(A) the Loans to be converted or continued, and, in the case of any LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan to be converted or continued, the last day of the Interest Period therefor, (B) the effective date of such conversion or continuation (which shall be a Business Day), (C) the principal amount of such Loans to be converted or continued, and (D) the Interest Period to be applicable to such converted or continued LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan. If the applicable Borrower fails to give a timely Notice of Conversion/Continuation prior to the end of the Interest Period for any LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan, then the applicable LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan shall automatically continue as a LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan (in each case having the same Interest Period as the then expiring Interest Period), as applicable. Any such automatic continuation shall be effective as of the last day of the Interest Period then in effect with respect to the applicable LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan. If the applicable Borrower requests a conversion to, or continuation of, LIBOR Rate Loans, SOFR Loans or CDOR Rate Loans, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month in the case of a conversion and an Interest Period that is the same as the then expiring Interest Period in the case of a continuation. Notwithstanding anything to the contrary herein, a Swingline Loan may not be converted to a LIBOR Rate Loan, SOFR Loan or CDOR Rate Loan. The Administrative Agent shall promptly notify the affected Lenders of such Notice of Conversion/Continuation.

SECTION 5.3 Fees.

(i)Commitment Fee. Commencing on the Closing Date, subject to Section 5.15(a)(iii)(A), the US Borrowers shall pay to the Administrative Agent, for the account of the Revolving Credit Lenders, a non-refundable commitment fee (the “Commitment Fee”) at a rate per annum equal to the Applicable Margin on the average daily unused portion of the Revolving Credit Commitment of the Revolving Credit Lenders (other than the Defaulting Lenders, if any); provided, that the amount of outstanding Swingline Loans shall not be considered usage of the Revolving Credit Commitment for the purpose of calculating the Commitment Fee. The Commitment Fee shall be payable in arrears on the last Business Day of each calendar quarter during the term of this Agreement commencing December 31, 2021 and ending on the date upon which all Obligations (other than contingent indemnification obligations not then due) arising under the Revolving Credit Facility shall have been indefeasibly and irrevocably paid and satisfied in full, all Letters of Credit have been terminated or expired (or been Cash Collateralized) and the Revolving Credit Commitment has been terminated. The Commitment Fee shall be distributed by the Administrative Agent to the Revolving Credit Lenders (other than any Defaulting Lender) pro rata in accordance with such Revolving Credit Lenders’ respective Revolving Credit Commitment Percentages.

(ii)Other Fees. The Borrowers shall pay to the Arrangers and the Administrative Agent for their own respective accounts fees in the amounts and at the times specified in any Fee Letter as applicable. The Borrowers shall pay to the Lenders such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified.

SECTION 5.4 Manner of Payment.

(i)Payments made by the Borrowers. Each payment by a Borrower on account of the principal of or interest on the Loans or of any fee, commission or other amounts (including the Reimbursement Obligations) payable to the Lenders under this Agreement shall be made not later than 1:00 p.m. on the date specified for payment under this Agreement to the Administrative Agent at the Administrative Agent’s Office for the account of the Lenders entitled to such payment, in immediately available funds and shall be made without any set off, counterclaim or deduction whatsoever. Any payment received after such time but before 2:00 p.m. on such day shall be deemed a payment on such date for the purposes of Section 10.1, but for all other purposes shall be deemed to have been made on the next succeeding Business Day. Any payment received after 2:00 p.m. shall be deemed to have been made on the next succeeding Business Day for all purposes. Upon receipt by the Administrative Agent of each such payment, the Administrative Agent shall distribute to each such Lender at its address for notices set forth herein its Commitment Percentage in respect of the relevant Credit Facility (or other applicable share as provided herein) of such payment and shall wire advice of the amount of such credit to each Lender. Each payment to the Administrative Agent on account of the principal of or interest on the Swingline Loans or of any fee, commission or other amounts payable to the applicable Swingline Lender shall be made in like manner, but for the account of the applicable Swingline Lender. Each payment to the Administrative Agent of any Issuing Lender’s fees or L/C Participants’

lxxiv

165457743_4174358596_2

commissions shall be made in like manner, but for the account of such Issuing Lender or the L/C Participants, as the case may be. Each payment to the Administrative Agent of Administrative Agent’s fees or expenses shall be made for the account of the Administrative Agent and any amount payable to any Lender under Sections 5.9, 5.10, 5.11 or 12.3 shall be paid to the Administrative Agent for the account of the applicable Lender. Subject to the definition of Interest Period, if any payment under this Agreement shall be specified to be made upon a day which is not a Business Day, it shall be made on the next succeeding day which is a Business Day and such extension of time shall in such case be included in computing any interest if payable along with such payment.

(ii)Defaulting Lenders. Notwithstanding the foregoing, if there exists a Defaulting Lender each payment by any Borrower to such Defaulting Lender hereunder shall be applied in accordance with Section 5.15(a)(ii).

SECTION 5.5 Evidence of Indebtedness.

(i)Extensions of Credit. The Extensions of Credit made by each Lender and each Issuing Lender shall be evidenced by one or more accounts or records maintained by such Lender or such Issuing Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender or the applicable Issuing Lender shall be conclusive absent manifest error of the amount of the Extensions of Credit made by the Lenders or such Issuing Lender to the applicable Borrowers and their applicable respective Subsidiaries and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrowers hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender or any Issuing Lender and the accounts and records of the Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the applicable Borrower shall execute and deliver to such Lender (through the Administrative Agent) a US Revolving Credit Note, Canadian Revolving Credit Note, a US Term Loan Note, a Canadian Term Loan Note, US Swingline Note and/or Canadian Swingline Note, as applicable, which shall evidence such Lender’s Revolving Credit Loans, Term Loans and/or Swingline Loans, as applicable, in addition to such accounts or records. Each Lender may attach schedules to its Notes and endorse thereon the date, amount and maturity of its Loans and payments with respect thereto.

(ii)Participations. In addition to the accounts and records referred to in subsection (a), each Revolving Credit Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Revolving Credit Lender of participations in Letters of Credit and Swingline Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Revolving Credit Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

SECTION 5.6 Sharing of Payments by Xxxxxxx. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Xxxxxx’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations (other than pursuant to Sections 5.9, 5.10, 5.11 or 12.3) greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that:

(1)if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and

(2)the provisions of this paragraph shall not be construed to apply to (A) any payment made by the Borrowers pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (B) the

lxxv

165457743_4174358596_2

application of Cash Collateral provided for in Section 5.14 or (C) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in Swingline Loans and Letters of Credit to any assignee or participant, other than to any of the Consolidated Companies or their Affiliates (as to which this Section 5.6 shall apply).

Each Credit Party consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Credit Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Credit Party in the amount of such participation.

SECTION 5.7 Administrative Agent’s Clawback.

(i)Funding by Xxxxxxx; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender (i) in the case of Base Rate Loans, not later than 12:00 noon on the date of any proposed borrowing, (ii) in the case of Canadian Revolving Credit Loans, not later than 12:00 noon one (1) Business Day before the date of any proposed borrowing and (iii) otherwise, prior to the proposed date of any borrowing that such Lender will not make available to the Administrative Agent such Xxxxxx’s share of such borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Sections 2.3(b) and 4.2 and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to the Administrative Agent, then the applicable Lender and the applicable Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the applicable Borrower to but excluding the date of payment to the Administrative Agent, (A) in the case of a payment to be made by such Lender, (1) with respect to any Loan denominated in Dollars, at the greater of (x) the daily average Federal Funds Rate and (y) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (2) with respect to any Loan denominated in Canadian Dollars, at the greater of (x) a rate equal to the Administrative Agent’s aggregate marginal cost (including the cost of maintaining any required reserves or deposit insurance and of any fees, penalties, overdraft charges or other costs or expenses incurred by the Administrative Agent as a result of the failure to deliver funds hereunder) of carrying such amount and (y) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (B) in the case of a payment to be made by such Borrower, (1) with respect to any Loan denominated in Dollars, the Base Rate and (2) with respect to any Loan denominated in Canadian Dollars, the Canadian Base Rate. If the applicable Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to such Borrower the amount of such interest paid by such Borrower for such period. If such Lender pays its share of the applicable borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by any Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

(ii)Payments by the Borrowers; Presumptions by Administrative Agent. Unless the Administrative Agent shall have received notice from the applicable Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders, any Issuing Lender or any Swingline Lender hereunder that the applicable Borrower will not make such payment, the Administrative Agent may assume that such Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders, such Issuing Lender or such Swingline Lender, as the case may be, the amount due. In such event, if the applicable Borrower has not in fact made such payment, then each of the Lenders, each Issuing Lender or each Swingline Lender, as the case maybe, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender, Issuing Lender or Swingline Lender, with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, (i) with respect to any Extension of Credit (other than any Canadian Revolving Credit Loan, any Canadian Swingline Loan and, to the extent applicable, any Incremental Term Loan made to the Canadian Borrowers), at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) with respect to any Canadian Revolving Credit Loan, any Canadian Swingline Loan and, to the extent applicable, any Incremental Term Loan made to the Canadian Borrowers,

lxxvi

165457743_4174358596_2

at a rate equal to the Administrative Agent’s aggregate marginal cost (including the cost of maintaining any required reserves or deposit insurance and of any fees, penalties, overdraft charges or other costs or expenses incurred by the Administrative Agent as a result of the failure to deliver funds hereunder) of carrying such amount.

(iii)Nature of Obligations of Lenders Regarding Extensions of Credit. The obligations of the Lenders under this Agreement to make the Loans and issue or participate in Letters of Credit and to make payments under this Section, Section 5.11(e), Section 11.11, Section 12.3(c) or Section 12.7, as applicable, are several and are not joint or joint and several. The failure of any Lender to make available its Commitment Percentage of any Loan requested by any Borrower shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Commitment Percentage of such Loan available on the borrowing date, but no Lender shall be responsible for the failure of any other Lender to make its Commitment Percentage of such Loan available on the borrowing date.

SECTION 5.8 Changed Circumstances.

(i)Circumstances Affecting LIBOR Rate, SOFR or CDOR Rate Availability. Subject to clause (c) below, in connection with any request for (x) a LIBOR Rate Loan (or a Base Rate Loan as to which the interest rate is determined with reference to LIBOR) or a conversion to or continuation thereof, (y) a SOFR Loan (or a Base Rate Loan as to which the interest rate is determined with reference to Adjusted Term SOFR) or a conversion to or continuation thereof or (zy) a CDOR Rate Loan (or a Canadian Base Rate Loan as to which the interest rate is determined with reference to the CDOR Rate or a conversion thereof) or otherwise, if for any reason

(2)(iii) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the LIBOR Rate, Adjusted Term SOFR or CDOR Rate, as applicable, does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loans during such Interest Period,

then, in each case, the Administrative Agent shall promptly give notice thereof to Centuri.

Each Lender agrees to designate a different Lending Office or assign its rights and obligations hereunder to another of its officers, branches or affiliates if such designation or assignment will avoid the need for such notice and will not, in the good faith judgment of such Lender, otherwise be materially disadvantageous to such Lender. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by such Lender in connection with any such designation or assignment.

165457743_4174358596_2

shall be deemed not to be a “Loan Document” for purposes of this Section 5.8(c)) if a Benchmark Transition Event (LIBOR) or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date (LIBORInitial Term Loan) have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (a)(1) or (a)(2) of the definition of “Benchmark Replacement (LIBORInitial Term Loan)” for such Benchmark Replacement Date (LIBORInitial Term Loan), such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (a)(3) of the definition of “Benchmark Replacement (LIBORInitial Term Loan)” for such Benchmark Replacement Date (LIBORInitial Term Loan), such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required Lenders. If an Unadjusted Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a monthly basis.

(a)Benchmark Replacement (Non-LIBORRevolver). Notwithstanding anything to the contrary herein or in any other Loan Document (and any Hedge Agreement shall be deemed not to be a “Loan Document” for purposes of this Section 5.8(c)), upon the occurrence of a Benchmark Transition Event (Non-LIBOR), the Administrative Agent and the Borrowers may amend this Agreement to replace the then-current Benchmark with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event (Non-LIBOR) will become effective at 5:00 p.m. on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all affected Lenders and the Borrowers so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders. No replacement of a Benchmark with a Benchmark Replacement pursuant to this Section 5.8(c)(i)(B) will occur prior to the applicable Benchmark Transition Start Date.

(C) Notwithstanding anything to the contrary herein or in any other Loan Document, if a Term SOFR Transition Event and its related Benchmark Replacement Date (LIBOR) have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document; provided that this clause (B) shall not be effective unless the Administrative Agent has delivered to the Lenders and the Borrower a Term SOFR Notice. For the avoidance of doubt, the Administrative Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may elect or not elect to do so in its sole discretion.

(2)Benchmark Replacement Conforming Changes. In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document.

(3)Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (A) any occurrence of a Benchmark Transition Event (LIBOR), a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date (LIBORInitial Term Loan), (B) the implementation of any

lxxix

165457743_4174358596_2

Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes, (D) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 5.8(c)(iv) below and (E) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 5.8(c), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion (and made in a manner substantially consistent with determinations being made for similarly situated customers of such Administrative Agent under agreements having provisions similar to this Section 5.8(c)) and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this Section 5.8(c).

(4)Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (A) if the then-current Benchmark is a term rate (including the Term SOFR Reference Rate or USD LIBOR) and either (1) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion (and made in a manner substantially consistent with determinations being made for similarly situated customers of such Administrative Agent under agreements having provisions similar to this Section 5.8(c)) or (2) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (B) if a tenor that was removed pursuant to clause (A) above either (1) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (2) is not, or is no longer, subject to an announcement that it is or will be no longer representative for a Benchmark (including a Benchmark Replacement), then the Administrative Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(5)Benchmark Unavailability Period. Upon Centuri’s receipt of notice of the commencement of a Benchmark Unavailability Period, the applicable Borrower may revoke any request for a borrowing of, conversion to or continuation of LIBOR Rate Loans or SOFR Loans (as applicable) to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the applicable Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to Base Rate Loans. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of the Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Base Rate.

(6)London Interbank Offered Rate Benchmark Transition Event. On March 5, 2021, the IBA, the administrator of the London interbank offered rate, and the FCA, the regulatory supervisor of the IBA, made the Announcements that the final publication or representativeness date for Dollars for (I) 1-week and 2-month London interbank offered rate tenor settings will be December 31, 2021 and (II) overnight, 1-month, 3-month, 6-month and 12-month London interbank offered rate tenor settings will be June 30, 2023. No successor administrator for the IBA was identified in such Announcements. The parties hereto agree and acknowledge that the Announcements resulted in the occurrence of a Benchmark Transition Event (LIBOR) with respect to the London interbank offered rate pursuant to the terms of this Agreement and that any obligation of the Administrative Agent to notify any parties of such Benchmark Transition Event (LIBOR) pursuant to clause (iii) of this Section 5.8(c) shall be deemed satisfied.

(iv)Illegality. Subject to Section 5.12, if, in any applicable jurisdiction, the Administrative Agent, any Issuing Lender or any Lender or its Applicable Designee determines that any Applicable Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for the Administrative Agent, any Issuing Lender, any Lender or any Applicable Designee to (i) perform any of its obligations hereunder or under any other Loan Document, (ii) to fund or maintain its participation in any Loan or (iii) issue, make,

lxxx

165457743_4174358596_2

maintain, fund or charge interest or fees with respect to any Extension of Credit to any Borrower that is a Foreign Subsidiary such Person shall promptly notify the Administrative Agent, then, upon the Administrative Agent notifying Centuri, and until such notice by such Person is revoked, any obligation of such Person to issue, make, maintain, fund or charge interest or fees with respect to any such Extension of Credit shall be suspended, and to the extent required by Applicable Law, cancelled. Upon receipt of such notice, the Credit Parties shall, (A) repay that Person’s participation in the Loans or other applicable Obligations on the last day of the Interest Period for each Loan or other Obligation occurring after the Administrative Agent has notified Centuri or, if earlier, the date specified by such Person in the notice delivered to the Administrative Agent (being no earlier than the last day of any applicable grace period permitted by Applicable Law) and (B) take all reasonable actions requested by such Person to mitigate or avoid such illegality.

SECTION 5.9 Indemnity. Each Borrower hereby indemnifies each of the Lenders against any loss or expense (including any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain a LIBOR Rate Loan, a SOFR Loan or a CDOR Rate Loan or from fees payable to terminate the deposits from which such funds were obtained) which may arise or be attributable to each Lender’s obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any Loan (a) as a consequence of any failure by such Borrower to make any payment when due of any amount due hereunder in connection with a LIBOR Rate Loan, a SOFR Loan or a CDOR Rate Loan, (b) due to any failure of such Borrower to borrow, continue or convert on a date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation or (c) due to any payment, prepayment or conversion of any LIBOR Rate Loan, any SOFR Loan or any CDOR Rate Loan on a date other than the last day of the Interest Period therefor. The amount of such loss or expense shall be determined, in the applicable Lender’s sole discretion, based upon the assumption that such Lender funded its Commitment Percentage of the LIBOR Rate Loans, SOFR Loans or CDOR Rate Loans, as applicable, and using any reasonable attribution or averaging methods which such Lender deems appropriate and practical. A certificate of such Lender setting forth the basis for determining such amount or amounts necessary to compensate such Lender shall be forwarded to the applicable Borrower through the Administrative Agent and shall be conclusively presumed to be correct save for manifest error. The applicable Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

SECTION 5.10 Increased Costs.

(i)Increased Costs Generally. If any Change in Law shall:

(1)impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or advances, loans or other credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Rate) or any Issuing Lender;

(2)subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (e) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(3)impose on any Lender or any Issuing Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender, the Issuing Lender or such other Recipient of making, converting to, continuing or maintaining any Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender, such Issuing Lender or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, such Issuing Lender or such other Recipient hereunder (whether of principal, interest or any other amount) then, upon written request of such Lender, such Issuing Lender or other Recipient, the Borrowers shall promptly pay to any such Lender, such Issuing Lender or other Recipient, as the case may

lxxxi

165457743_4174358596_2

be, such additional amount or amounts as will compensate such Lender, such Issuing Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(ii)Capital Requirements. If any Lender or any Issuing Lender determines that any Change in Law affecting such Lender or such Issuing Lender or any Lending Office of such Lender or such Lender’s or such Issuing Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Lender’s capital or on the capital of such Lender’s or such Issuing Lender’s holding company, if any, as a consequence of this Agreement, the Revolving Credit Commitment of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by such Issuing Lender, to a level below that which such Lender or such Issuing Lender or such Lender’s or such Issuing Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Lender’s policies and the policies of such Lender’s or such Issuing Lender’s holding company with respect to capital adequacy or liquidity), then from time to time upon written request of such Lender or such Issuing Lender the Borrowers shall promptly pay to such Lender or such Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Lender or such Lender’s or such Issuing Lender’s holding company for any such reduction suffered.

(iii)Certificates for Reimbursement. A certificate of a Lender, or an Issuing Lender or such other Recipient setting forth the amount or amounts necessary to compensate such Lender or such Issuing Lender, such other Recipient or any of their respective holding companies, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Borrowers, shall be conclusive absent manifest error. The Borrowers shall pay such Lender or such Issuing Lender or such other Recipient, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(iv)Delay in Requests. Failure or delay on the part of any Lender or any Issuing Lender or such other Recipient to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Lender’s or such other Recipient’s right to demand such compensation; provided that the Borrowers shall not be required to compensate any Lender or an Issuing Lender or any other Recipient pursuant to this Section for any increased costs incurred or reductions suffered more than six (6) months prior to the date that such Lender or such Issuing Lender or such other Recipient, as the case may be, notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s or such Issuing Lender’s or such other Recipient’s intention to claim compensation therefor (except that if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

SECTION 5.11 Taxes.

(i)Defined Terms. For purposes of this Section 5.11, the term “Lender” includes any Issuing Lender and the term “Applicable Law” includes FATCA.

(ii)Payments Free of Taxes. Any and all payments by or on account of any obligation of any Credit Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Credit Party shall be increased as necessary so that, after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section), the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(iii)Payment of Other Taxes by the Credit Parties. The Credit Parties shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

lxxxii

165457743_4174358596_2

(iv)Indemnification by the Credit Parties. With respect to any Indemnified Taxes arising from US Obligations, the US Credit Parties shall jointly and severally indemnify each Recipient, within ten (10) days after written demand therefor, for the full amount of any such Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. With respect to any Indemnified Taxes arising from Canadian Obligations, the Credit Parties shall jointly and severally indemnify each Recipient, within ten (10) days after written demand therefor, for the full amount of any such Indemnified Taxes (including Indemnified Taxes imposed on or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrowers by a Recipient (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Recipient, shall be conclusive absent manifest error.

(v)Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Credit Party has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Credit Parties to do so), (ii) any Taxes attributable to such Xxxxxx’s failure to comply with the provisions of Section 12.9(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(vi)Evidence of Payments. As soon as practicable after any payment of Taxes by any Credit Party to a Governmental Authority pursuant to this Section 5.11, such Credit Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(vii)Status of Lenders.

(1)Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to Centuri and the Administrative Agent, at the time or times reasonably requested by Centuri or the Administrative Agent, such properly completed and executed documentation reasonably requested by Centuri or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Centuri or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by Centuri or the Administrative Agent as will enable Centuri or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.11(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(2)Without limiting the generality of the foregoing:

lxxxiii

165457743_4174358596_2

(a)Any Lender that is a U.S. Person shall deliver to Centuri and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Centuri or the Administrative Agent), executed originals of IRS Form W-9 (or any successor form) certifying that such Lender is exempt from United States federal backup withholding tax;

(b)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Centuri and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Centuri or the Administrative Agent), whichever of the following is applicable:

(2) executed copies of IRS Form W-8ECI (or any successor form);

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit H-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of a US Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN (or any successor form) or W-8BEN-E (or any successor form), as applicable; or

(4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY (or any successor form), accompanied by IRS Form W-8ECI (or any successor form), IRS Form W-8BEN (or any successor form) or W-8BEN-E (or any successor form), a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-2 or Exhibit H-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-4 on behalf of each such direct and indirect partner;

(c)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Centuri and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of Centuri or the Administrative Agent), executed copies of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the US Borrowers or the Administrative Agent to determine the withholding or deduction required to be made; and

(d)if a payment made to a Lender under any Loan Document would be subject to United States federal withholding Tax imposed by FATCA if such Lender were to fail to

lxxxiv

165457743_4174358596_2

comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to Centuri and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by Centuri or the Administrative Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by Centuri or the Administrative Agent as may be necessary for the US Borrowers and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Xxxxxx’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that (x) it shall promptly notify Centuri and the Administrative Agent of any change in circumstances which would modify or render invalid any claimed exemption or reduction to withholding and (y) if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Centuri and the Administrative Agent in writing of its legal inability to do so; provided that no such updating or notification is required to be made on account of any Canadian withholding tax if no form or certification has been previously delivered for Canadian withholding tax purposes.

(viii)Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.11 (including by the payment of additional amounts pursuant to this Section 5.11), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(ix)Survival. Each party’s obligations under this Section 5.11 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

SECTION 5.12 Mitigation Obligations; Replacement of Lenders.

(i)Designation of a Different Lending Office. If any Lender requests compensation under Section 5.10, or requires any Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.11, or determines that it is unable to fulfill its obligations hereunder due to illegality pursuant to Section 5.8(d), then such Lender shall, at the request of the Borrowers, use reasonable efforts to designate a different Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.10 or Section 5.11 or avoid illegality under Section 5.8(d), as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

lxxxv

165457743_4174358596_2

(ii)Replacement of Lenders. If any Lender requests compensation under Section 5.10, or if the Borrowers are required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.11, or any Lender determines that it is unable to fulfill its obligations hereunder due to illegality pursuant to Section 5.8(d) and, in each case, such Lender has declined or is unable to designate a different Lending Office in accordance with Section 5.12(a), or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.9), all of its interests, rights (other than its existing rights to payments pursuant to Section 5.10 or Section 5.11) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(1)the Borrowers shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 12.9;

(2)such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and funded participations in Letters of Credit and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 5.9) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts);

(3)in the case of any such assignment resulting from a claim for compensation under Section 5.10 or payments required to be made pursuant to Section 5.11, such assignment will result in a reduction in such compensation or payments thereafter;

(4)such assignment does not conflict with Applicable Law; and

(5)in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

Each party hereto agrees that (x) an assignment required pursuant to this Section 5.12 may be effected pursuant to an Assignment and Assumption executed by Centuri, the Administrative Agent and the assignee and (y) the Lender required to make such assignment need not be a party thereto in order for such assignment to be effective and shall be deemed to have consented to and be bound by the terms thereof; provided that, following the effectiveness of any such assignment, the other parties to such assignment agree to execute and deliver such documents necessary to evidence such assignment as reasonably requested by the applicable Lender or the Administrative Agent, provided, further that any such documents shall be without recourse to or warranty by the parties thereto.

SECTION 5.13 Incremental Loans.

(i)Request for Increase. At any time after the Closing Date, upon written notice to the Administrative Agent, the US Borrowers, or the Canadian Borrowers, as applicable, may, from time to time, request (i) one or more incremental term loans, including a borrowing of an additional term loan, the principal amount of which will be added to the tranche of Term Loan with the latest maturity date (an “Incremental Term Loan”) or (ii) one or more increases in the Revolving Credit Commitments (an “Incremental Revolving Credit Facility Increase” and, together with the initial principal amount of the Incremental Term Loans, the “Incremental Increases”); provided that (A) the aggregate principal amount for all such Incremental Increases and Incremental Equivalent Indebtedness incurred after the Closing Date shall not exceed the sum of (1) the greater of $300,000,000 and Consolidated EBITDA as of the most recently ended four consecutive fiscal quarter period for which financial statements and the related Officer’s Compliance Certificate have

Incremental Term Loans may be made to the US Borrowers in Dollars or to the Canadian Borrowers in Canadian Dollars. Unless the applicable Borrower otherwise notifies the Administrative Agent, if all or any portion of any Incremental Increases or Incremental Equivalent Indebtedness would be permitted under clause (A)(2) above on the applicable date of incurrence, such Incremental Increases or Incremental Equivalent Indebtedness (or the relevant portion thereof) shall be deemed to have been incurred in reliance on clause (A)(2) above prior to the utilization of any amount available under clause (A)(1) above.

(ii)Incremental Lenders. Each notice from the applicable Borrower pursuant to this Section shall set forth the requested amount, currency and proposed terms of the relevant Incremental Increase. Incremental Increases may be provided by any existing Lender or by any other Persons (an “Incremental Lender”); provided that the Administrative Agent, each Issuing Lender and/or each Swingline Lender, as applicable, shall have consented (not to be unreasonably withheld, conditioned or delayed) to such Incremental Lender’s providing such Incremental Increases to the extent any such consent would be required under Section 12.9(b) for an assignment of Loans or Revolving Credit Commitments, as applicable, to such Incremental Lender.

Each proposed Incremental Lender may elect or decline, in its sole discretion, and shall notify the Administrative Agent within such time period whether it agrees, to provide an Incremental Increase and, if so, whether by an amount equal to, greater than or less than requested. Any Person not responding within such time period shall be deemed to have declined to provide an Incremental Increase.

(iii)Increase Effective Date and Allocations. The Administrative Agent and the applicable Borrower shall determine the effective date (the “Increase Effective Date”) and the final allocation of such Incremental Increase (limited in the case of the Incremental Lenders to their own respective allocations thereof).

(iv)Terms of Incremental Increases. The terms of each Incremental Increase (which shall be set forth in the relevant Incremental Amendment) shall be determined by the applicable Borrowers and the applicable Incremental Lenders; provided that:

(1)in the case of each Incremental Term Loan (the terms of which shall be set forth in the relevant Incremental Amendment):

(a)the maturity of any such Incremental Term Loan shall not be earlier than the then the latest scheduled maturity date of the Loans and Commitments in effect as of the Increase Effective Date and the Weighted Average Life to Maturity of any such Incremental Term Loan shall not be shorter than the remaining Weighted Average Life to Maturity of such latest maturing Term Loans; provided that the restrictions of this clause (A) shall not apply to the extent such Incremental Term Loan constitutes a customary bridge or similar facility that is to be automatically converted or exchanged into notes or other permitted Indebtedness that otherwise would satisfy this clause (A) so long as such conversion or

lxxxvii

165457743_4174358596_2

(c)any mandatory prepayment (other than scheduled amortization payments) of each Incremental Term Loan shall be made on a pro rata basis with all then existing Term Loans, except that the applicable Borrower and the Incremental Lenders in respect of such Incremental Term Loan may, in their sole discretion, elect to prepay or receive, as applicable, any prepayments on a less than pro rata basis (but not on a greater than pro rata basis); and

(d)except as provided above, all other terms and conditions applicable to any Incremental Term Loan shall be consistent with the terms and conditions of the Initial Term Loan or otherwise reasonably satisfactory to the Administrative Agent and the applicable Borrower (provided that such other terms and conditions, taken as a whole, shall not be more favorable to the Lenders under any Incremental Term Loans than such other terms and conditions, taken as a whole, under the Initial Term Loans);

(2)in the case of each Incremental Revolving Credit Facility Increase (the terms of which shall be set forth in the relevant Incremental Amendment):

(a)Revolving Credit Loans made with respect to the Incremental Revolving Credit Facility Increase shall mature on the Revolving Credit Maturity Date and shall bear interest at the rate applicable to the Revolving Credit Loans;

(B) the outstanding Revolving Credit Loans and Revolving Credit Commitment Percentages of Swingline Loans and L/C Obligations will be reallocated by the Administrative Agent on the applicable Increase Effective Date among the Revolving Credit Lenders (including the Incremental Lenders providing such Incremental Revolving Credit Facility Increase) in accordance with their revised Revolving Credit Commitment Percentages (and the Revolving Credit Lenders (including the Incremental Lenders providing such Incremental Revolving Credit Facility Increase) agree to make all payments and adjustments necessary to effect such reallocation and the applicable Borrower shall pay any and all costs required pursuant to Section 5.9 in connection with such reallocation as if such reallocation were a repayment); and

(C) except as provided above, all of the other terms and conditions applicable to such Incremental Revolving Credit Facility Increase shall, except to the extent otherwise provided in this Section 5.13, be identical to the terms and conditions applicable to the Revolving Credit Facility, including the Applicable Margin and unused fees (but may have different upfront fees);

(3)each Incremental Increase shall constitute US Obligations of the US Borrowers or Canadian Obligations of the Canadian Borrowers, as applicable, and shall be secured and guaranteed with the other Extensions of Credit on a pari passu basis; and

(4)any Incremental Lender with an Incremental Revolving Credit Facility Increase shall be entitled to the same voting rights as the existing Revolving Credit Lenders under the

Revolving Credit Facility and any Extensions of Credit made in connection with each Incremental Revolving Credit Facility Increase shall receive proceeds of prepayments on the same basis as the other Revolving Credit Loans made hereunder.

(v)Conditions to Effectiveness of Incremental Increases. Any Incremental Increase shall become effective as of such Increase Effective Date and shall be subject to the following conditions precedent, which, in the case of an Incremental Term Loan incurred solely to finance a substantially concurrent Limited Condition Acquisition, shall be subject to Section 1.12:

(1)no Default or Event of Default shall exist on such Increase Effective Date immediately prior to or after giving effect to (A) such Incremental Increase or (B) the making of any Extensions of Credit pursuant thereto;

(2)all of the representations and warranties set forth in Article VII shall be true and correct in all material respects (or if qualified by materiality or Material Adverse Effect, in all respects) as of such Increase Effective Date, or if such representation speaks as of an earlier date, as of such earlier date;

(3)the Administrative Agent shall have received from Centuri, an Officer’s Compliance Certificate demonstrating that the Consolidated Companies are in pro forma compliance with the financial covenants set forth in Section 9.13 (based on the financial statements most recently delivered pursuant to Section 8.1) after giving effect to such Incremental Increase (assuming that the entire applicable Incremental Term Loan and/or Incremental Revolving Credit Facility Increase is fully funded on the effective date thereof) and any Permitted Acquisition, refinancing of Indebtedness or other event consummated in connection therewith giving rise to a Pro Forma Basis adjustment;

(4)the Credit Parties shall have executed an Incremental Amendment in form and substance reasonably acceptable to the applicable Borrower and the applicable Incremental Lenders; and

(5)the Administrative Agent shall have received from the applicable Borrower, any customary legal opinions or other documents (including a resolution duly adopted by the board of directors (or equivalent governing body) of each Credit Party authorizing such Incremental Increase), and other documents reasonably requested by Administrative Agent in connection with such Incremental Increase.

(vi)Incremental Amendments. Each such Incremental Increase shall be effected pursuant to an amendment (an “Incremental Amendment”) to this Agreement and, as appropriate, the other Loan Documents, executed by the Credit Parties, the Administrative Agent and the applicable Incremental Lenders, which Incremental Amendment may, without the consent of any other Lenders, effect such amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the Administrative Agent, to effect the provisions of this Section 5.13;

(vii)Conflicting Provisions. This Section shall supersede any provisions in Section 5.6 or 12.2 to the contrary.

SECTION 5.14 Cash Collateral. At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent, any Issuing Lender (with a copy to the Administrative Agent) or any Swingline Lender (with a copy to the Administrative Agent), the Borrowers shall Cash Collateralize the Fronting Exposure of such Issuing Lender and/or such Swingline Lender, as applicable, with respect to such Defaulting Lender (determined after giving effect to Section 5.15(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount.

(i)Grant of Security Interest. Each Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of each Issuing Lender and each Swingline Lender, and agrees to maintain, a first priority security interest in all such Cash

lxxxix

165457743_4174358596_2

Collateral as security for the Defaulting Lender’s obligation to fund participations in respect of L/C Obligations and Swingline Loans, to be applied pursuant to subsection (b) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent, each Issuing Lender and each Swingline Lender as herein provided (other than Permitted Liens in favor of a depository bank), or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrowers will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii)Application. Notwithstanding anything to the contrary contained in this Agreement or any other Loan Document, Cash Collateral provided under this Section 5.14 or Section 5.15 in respect of Letters of Credit and Swingline Loans shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of L/C Obligations and Swingline Loans (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii)Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce the Fronting Exposure of any Issuing Lender and/or any Swingline Lender, as applicable, shall no longer be required to be held as Cash Collateral pursuant to this Section 5.14 following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Administrative Agent, the Issuing Lenders and the Swingline Lenders that there exists excess Cash Collateral; provided that, subject to Section 5.15, the Person providing Cash Collateral, the Issuing Lenders and the Swingline Lenders may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations.

SECTION 5.15 Defaulting Lenders.

(i)Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by Applicable Law:

(1)Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definitions of “Required Lenders”, “Required Revolving Credit Lenders” or “Required Term Loan Lenders” and Section 12.2.

(2)Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 12.4 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Lenders or the Swingline Lenders hereunder; third, to Cash Collateralize the Fronting Exposure of the Issuing Lenders and the Swingline Lenders with respect to such Defaulting Lender in accordance with Section 5.14; fourth, as the Borrowers may request (so long as no Default or Event of Default exists), to the funding of any Loan or funded participation in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrowers, to be held in a deposit account and released pro rata in order to (A) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans and funded participations under this Agreement and (B) Cash Collateralize the Issuing Lenders’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit and Swingline Loans issued under this Agreement, in accordance with Section 5.14; sixth, to the payment of any amounts owing to the Lenders, the Issuing Lenders or the Swingline Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any Issuing Lender or any Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts

165457743_4174358596_2

owing to any Borrower as a result of any judgment of a court of competent jurisdiction obtained by such Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (1) such payment is a payment of the principal amount of any Loans or funded participations in Letters of Credit or Swingline Loans in respect of which such Defaulting Lender has not fully funded its appropriate share, and (2) such Loans were made or the related Letters of Credit or Swingline Loans were issued at a time when the conditions set forth in Section 6.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and funded participations in Letters of Credit or Swingline Loans owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or funded participations in Letters of Credit or Swingline Loans owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Obligations and Swingline Loans are held by the Lenders pro rata in accordance with the Revolving Credit Commitments under the applicable Revolving Credit Facility without giving effect to Section 5.15(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 5.15(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(3)Certain Fees.

(a)No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(b)Each Defaulting Lender shall be entitled to receive letter of credit commissions pursuant to Section 3.3 for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Revolving Credit Commitment Percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 5.14.

(c)With respect to any Commitment Fee or letter of credit commission not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrowers shall (1) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in L/C Obligations or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2) pay to each applicable Issuing Lender and Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Lender’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee.

(4)Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in L/C Obligations and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Revolving Credit Commitment Percentages (calculated without regard to such Defaulting Lender’s Revolving Credit Commitment) but only to the extent that (x) the conditions set forth in Section 6.2 are satisfied at the time of such reallocation (and, unless the Borrowers shall have otherwise notified the Administrative Agent at such time, the Borrowers shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Revolving Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Revolving Credit Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Xxxxxx having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Xxxxxx’s increased exposure following such reallocation.

xci

165457743_4174358596_2

(5)Cash Collateral, Repayment of Swingline Loans. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrowers shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first, repay Swingline Loans in an amount equal to the Swingline Lenders’ Fronting Exposure and (y) second, Cash Collateralize the Issuing Lenders’ Fronting Exposure in accordance with the procedures set forth in Section 5.14.

(ii)Defaulting Lender Cure. If the Borrowers, the Administrative Agent, the Issuing Lenders and the Swingline Lenders agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with the Commitments under the applicable Credit Facility (without giving effect to Section 5.15(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Xxxxxx was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Xxxxxx’s having been a Defaulting Lender.

SECTION 5.16 Centuri as Agent for the Borrowers; Nature of Obligations.

(i)Each Borrower hereby irrevocably appoints and authorizes Centuri (a) to provide the Administrative Agent with all notices with respect to Loans obtained for the benefit of such Borrower and all other notices and instructions under this Agreement, (b) to take such action on behalf of such Borrower as Centuri deems appropriate on its behalf to such Borrower Loans or Letters of Credit and to exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement and (c) to act as its agent for service of process and notices required to be delivered under this Agreement or the other Loan Documents, it being understood and agreed that receipt by Centuri of any summons, notice or other similar item shall be deemed effective receipt by the Consolidated Companies.

(ii)Notwithstanding anything to contrary contained in the Loan Documents, (a) the US Borrowers shall be jointly and severally liable for all Obligations and (b) the Canadian Borrowers shall be jointly and severally liable for all Canadian Obligations, but in no event shall any Canadian Borrower have any obligation with respect to the US Obligations. In the event of any conflict or inconsistency between this Section 5.16(b) and any other provision of any Loan Document, this Section 5.16(b) shall control.

SECTION 5.17 Additional Borrowers. Subject to Section 8.14, Centuri may at any time, upon not less than fifteen (15) Business Days’ notice from Centuri to the Administrative Agent and the Lenders (or such shorter period as may be agreed by the Administrative Agent in its sole discretion), request that a Wholly-Owned US Subsidiary or Wholly-Owned Canadian Subsidiary (each, an “Applicant Borrower”) be designated as an Additional Borrower to receive Loans and request Letters of Credit hereunder by delivering to the Administrative Agent (which shall promptly deliver counterparts thereof to each Lender) a duly executed notice and agreement in substantially the form of Exhibit I (an “Additional Borrower Request and Assumption Agreement”); provided that no US Subsidiary or Canadian Subsidiary may be designated as an Additional Borrower without the consent of each Revolving Credit Lender unless such US Subsidiary or Canadian Subsidiary is already a US Subsidiary Guarantor or Canadian Subsidiary Guarantor, as applicable. The parties hereto acknowledge and agree that prior to any Applicant Borrower becoming entitled to utilize the Credit Facilities, the Administrative Agent and the Lenders shall have received such supporting Security Documents, supplements to the Loan Documents, resolutions, incumbency certificates, opinions of counsel, all documentation and other information in order to comply with requirements of any Anti-Money Laundering Laws including, without limitation, the PATRIOT Act and any applicable “know your customer” rules and regulations, Beneficial Ownership Certification and other documents or information, in form, content and scope reasonably satisfactory to the Administrative Agent, as may be required by the Administrative Agent or the Lenders in their sole discretion, and Notes signed by such new Borrowers to the extent any Lenders so require.

xcii

165457743_4174358596_2

receipt of all such requested documents and information described above, the Administrative Agent shall send a notice in substantially the form of Exhibit J (an “Additional Borrower Notice”) to Centuri and the Lenders specifying the effective date upon which the Applicant Borrower shall constitute an Additional Borrower for purposes hereof, whereupon each of the Lenders agrees to permit such Additional Borrower to receive Loans and request Letters of Credit hereunder, on the terms and conditions set forth herein, and each of the parties agrees that such Additional Borrower otherwise shall be a Borrower for all purposes of this Agreement; provided that no Notice of Borrowing or Letter of Credit Application may be submitted by or on behalf of such Additional Borrower until the date five (5) Business Days after such effective date.

SECTION 5.18 Refinancing Facilities.

(i)The Borrowers may by written notice to the Administrative Agent elect to request the establishment of (i) one or more additional tranches or Classes of term loans under this Agreement (“Refinancing Term Loans”) or one or more series of debt securities (“Refinancing Notes”), which refinance, renew, replace, defease or refund (collectively, “Refinance”) one or more Classes of Term Loans under this Agreement or (ii) one or more additional revolving facilities under this Agreement providing for revolving commitments (“Refinancing Revolving Credit Commitments” and the revolving loans thereunder, “Refinancing Revolving Loans”) which Refinances one or more Classes of Revolving Credit Commitments (and Revolving Credit Loans thereunder) under this Agreement; provided that:

(1)no Default or Event of Default has occurred and is continuing or would result therefrom;

(4)the other terms and conditions of such Refinancing Debt or Refinancing Revolving Credit Commitments (except as otherwise provided in clause (iii) above and with respect to pricing, interest rate margins, premiums, discounts, fees, rate floors and optional prepayment or redemption terms), taken as a whole shall (as reasonably determined by the Borrowers) be substantially similar to, or (taken as a whole) not materially less favorable to the Borrowers and their respective Subsidiaries than, the terms, taken as a whole, applicable to Term Loans or Revolving Credit Commitments being Refinanced, except to the extent such covenants and other terms apply solely to any period after the latest final Term Loan Maturity Date or Revolving Credit Maturity Date of the Term Loans and/or Revolving Credit Commitments being Refinanced (or, in the case of any unsecured or junior lien Refinancing Debt, after the date that is 91 days after such latest final Term Loan Maturity Date or Revolving Credit Maturity Date);

(5)the proceeds of such Refinancing Debt, Refinancing Revolving Credit Commitments or Refinancing Revolving Loans shall be applied, concurrently or substantially concurrently with the incurrence thereof (in accordance with Section 4.4(b)(i)), solely to the repayment of the outstanding amount of one or more Classes of Term Loans or permanently reduce one or more Classes of Revolving Credit Commitments and Revolving Credit Loans, as the case may be, being Refinanced thereby;

(6)each Class of Refinancing Term Loans or Refinancing Revolving Credit Commitments shall be in an aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in

(8)Refinancing Debt, Refinancing Revolving Credit Commitments and/or Refinancing Revolving Loans may be unsecured or may only be secured by the Collateral and may rank pari passu or junior in right of payment and/or security with the remaining Revolving Credit Commitments, Revolving Credit Loans and/or Term Loans, so long as the holders of any Refinancing Debt, Refinancing Revolving Credit Commitments and/or Refinancing Revolving Loans that are junior in right of payment and/or security are subject to an Acceptable Intercreditor Agreement;

(9)such Refinancing Debt or Refinancing Revolving Credit Commitments shall not be secured by any asset of the Borrowers and their respective Subsidiaries other than the Collateral;

(10)in the case of any Refinancing Revolving Credit Commitments, substantially concurrently with the effectiveness thereof, all the Revolving Credit Commitments then in effect shall be terminated, and all the Revolving Credit Loans then outstanding, together with all interest thereon, and all other amounts accrued for the benefit of the Revolving Credit Lenders, shall be repaid or paid (it being understood, however, that any Letters of Credit may continue to be outstanding hereunder), and the aggregate amount of such Refinancing Revolving Credit Commitments does not exceed the aggregate amount of the Revolving Credit Commitments so terminated; and

(11)any mandatory prepayment requirements, in the case of any Refinancing Term Loans, may provide that such Refinancing Term Loans may participate in any mandatory prepayment on a pro rata basis with any Class of existing Term Loans, but may not provide for prepayment requirements that are more favorable to the Lenders holding such Refinancing Term Loans than to the Lenders holding such Class of Term Loans.

(ii)Each such notice shall specify the date (each, a “Refinancing Effective Date”) on which the applicable Borrower proposes that the Refinancing Debt be made or the Refinancing Revolving Credit Commitments shall become effective, which shall be a date not less than three (3) Business Days (or such shorter period as may be agreed to by the Administrative Agent) after the date on which such notice is delivered to the Administrative Agent.

Any Refinancing Term Loans or Refinancing Revolving Credit Commitment made on any Refinancing Effective Date shall be designated a series (a “Refinancing Series”) of Refinancing Term Loans or Refinancing Revolving Credit Commitments for all purposes of this Agreement; provided that (i) any Refinancing Term Loans may, to the extent provided in the applicable Refinancing Amendment, be designated as an increase in any previously established Refinancing Series of Refinancing Term Loans made to the applicable Borrower and (ii) any Refinancing Revolving Credit Commitments may, to the extent provided in the applicable Refinancing Amendment, be designated as an increase in any previously established Refinancing Series of Refinancing Revolving Credit Commitments.

(iv)The Administrative Agent and the Lenders hereby consent to the transactions contemplated by this Section 5.18 (including, for the avoidance of doubt, the payment of interest, fees, amortization or premium in respect of the Refinancing Term Loans and Refinancing Revolving Credit Commitments, and Refinancing Revolving Loans on the terms specified by the Borrowers) and hereby waive the requirements of this Agreement (including, but not limited to, Section 5.6 and Section 12.2) or any other Loan Document that

xciv

165457743_4174358596_2

may otherwise prohibit such Refinance or any other transaction contemplated by this Section 5.18. The Refinancing Term Loans and Refinancing Revolving Credit Commitments shall be established pursuant to an amendment to this Agreement among the applicable Borrower and the applicable Refinancing Lenders providing such Refinancing Term Loans or Refinancing Revolving Credit Commitments (a “Refinancing Amendment”) which shall be consistent with the provisions set forth in this Section 5.18. The Refinancing Notes shall be established pursuant to documentation which shall be consistent with the provisions set forth in Section 5.18(a). Each Refinancing Amendment shall be binding on the Lenders, the Administrative Agent, the Credit Parties party thereto and the other parties hereto without the consent of any other Lender (except with respect to Refinancing Revolving Credit Commitments as provided above) and the Lenders hereby irrevocably authorize the Administrative Agent to enter into amendments to this Agreement and the other Loan Documents as may be necessary or appropriate in the reasonable opinion of the Administrative Agent and the Borrowers, to effect the provisions of this Section 5.18, including in order to establish new tranches or sub-tranches in respect of the Refinancing Term Loans or Refinancing Revolving Credit Commitments and Refinancing Revolving Loans and such technical amendments as may be necessary or appropriate in connection therewith and to adjust the amortization schedule in Section 4.3(a) (insofar as such schedule relates to payments due to Lenders, the Term Loans of which are Refinanced; provided that no such amendment shall reduce the pro rata share of any such payment that would have otherwise been payable to the Lenders, the Term Loans of which are not Refinanced).

SECTION 7.4 Compliance of Agreement, Loan Documents and Borrowing with Laws, Etc. The execution, delivery and performance by each Credit Party of the Loan Documents to which each such Credit Party is a party, in accordance with their respective terms, the Extensions of Credit hereunder and the transactions contemplated hereby or thereby do not and will not, by the passage of time, the giving of notice or otherwise, (a) require any Governmental Approval or violate any Applicable Law relating to any Credit Party or any Subsidiary thereof where the failure to obtain such Governmental Approval or such violation could reasonably be expected to have a Material Adverse Effect, (b) conflict with, result in a breach of or constitute a default under the articles of incorporation, bylaws or other organizational documents of any Credit Party or any Subsidiary thereof, (c) conflict with, result in a breach of or constitute a default under any

Each Credit Party and each Subsidiary thereof (a) has all Governmental Approvals required by any Applicable Law for it to conduct its business, each of which is in full force and effect, is final and not subject to review on appeal and is not the subject of any pending or, to its knowledge, threatened in writing attack by direct or collateral proceeding, (b) is in compliance with each Governmental Approval applicable to it and in compliance with all other Applicable Laws relating to it or any of its properties and (c) has timely filed all material reports, documents and other materials required to be filed by it under all Applicable Laws with any Governmental Authority and has retained all material records and documents required to be retained by it under Applicable Law except in each case (a), (b) or (c) where the failure to have, comply or file could not reasonably be expected to have a Material Adverse Effect.

If the amount of the first currency exceeds the amount originally due to a Secured Party in the first currency under this Agreement, such Secured Party shall promptly remit such excess to the Credit Parties. The covenants contained in this Section 10.7 shall survive the termination of the Loan Documents and payment of the obligations hereunder.

It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of

cxxxii

165457743_4174358596_2

any Applicable Law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

(ii)The Administrative Agent shall also act as the “collateral agent” under the Loan Documents, and each of the Lenders (including each holder of Secured Hedge Obligations and Secured Cash Management Obligations) and the Issuing Lenders hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and such Issuing Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Credit Parties to secure any of the Secured Obligations, together with such powers and discretion as are reasonably incidental thereto (including, without limitation, to enter into additional Loan Documents or supplements to existing Loan Documents on behalf of the Secured Parties). In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to this Article XI for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Security Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent), shall be entitled to the benefits of all provisions of Articles XI and XII (including Section 12.3, as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto.

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of banking, trust, financial advisory, underwriting, capital markets or other business with the Consolidated Companies or other Affiliates thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders or to provide notice to or consent of the Lenders with respect thereto.

SECTION 11.3 Exculpatory Provisions.

(3)shall not, have any duty to disclose, and shall not be liable for the failure to disclose to any Lender, any Issuing Lender or any other Person, any credit or other information relating concerning the business, prospects, operations, properties, assets, financial or other condition or creditworthiness of the Consolidated Companies or any of their respective Subsidiaries or Affiliates that is communicated to, obtained by or otherwise in the possession of the Person serving as the Administrative Agent, the Arrangers or their respective Related Parties in any capacity, except for notices, reports and other documents that are required to be furnished by the Administrative Agent to the Lenders pursuant to the express provisions of this Agreement; and

The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an Issuing Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender or such Issuing Lender unless the Administrative Agent shall have received notice to the contrary from such Lender or such Issuing Lender prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Credit Facility as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable

cxxxiv

165457743_4174358596_2

judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 12.3 shall continue in effect for the benefit of such retiring or removed Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Administrative Agent was acting as Administrative Agent or relating to its duties as Administrative Agent that are carried out following its retirement or removal, including, without limitation, any actions taken with respect to acting as collateral agent or otherwise holding any Collateral on behalf of any of the Secured Parties or in respect of any actions taken in connection with the transfer of agency to a replacement or successor Administrative Agent.

(iv)Any resignation by, or removal of, Wells Fargo as Administrative Agent pursuant to this Section shall also constitute its resignation as an Issuing Lender and Swingline Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Xxxxxxx Xxxxxx, if in its sole discretion it elects to, and Swingline Lender, (b) the retiring Issuing Lender and Swingline Lender shall be

cxxxv

165457743_4174358596_2

discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor Xxxxxxx Xxxxxx, if in its sole discretion it elects to, shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Issuing Lender to effectively assume the obligations of the retiring Issuing Lender with respect to such Letters of Credit.

SECTION 11.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and each Issuing Lender expressly acknowledges that none of the Administrative Agent, any Arranger or any of their respective Related Parties has made any representations or warranties to it and that no act taken or failure to act by the Administrative Agent, any Arranger or any of their respective Related Parties, including any consent to, and acceptance of any assignment or review of the affairs of the Consolidated Companies and their Subsidiaries or Affiliates shall be deemed to constitute a representation or warranty of the Administrative Agent, any Arranger or any of their respective Related Parties to any Lender, any Issuing Lender or any other Secured Party as to any matter, including whether the Administrative Agent, any Arranger or any of their respective Related Parties have disclosed material information in their (or their respective Related Parties’) possession. Each Lender and each Issuing Lender expressly acknowledges, represents and warrants to the Administrative Agent and each Arranger that (a) the Loan Documents set forth the terms of a commercial lending facility, (b) it is engaged in making, acquiring, purchasing or holding commercial loans in the ordinary course and is entering into this Agreement and the other Loan Documents to which it is a party as a Lender for the purpose of making, acquiring, purchasing and/or holding the commercial loans set forth herein as may be applicable to it, and not for the purpose of making, acquiring, purchasing or holding any other type of financial instrument, (c) it is sophisticated with respect to decisions to make, acquire, purchase or hold the commercial loans applicable to it and either it or the Person exercising discretion in making its decisions to make, acquire, purchase or hold such commercial loans is experienced in making, acquiring, purchasing or holding commercial loans, (d) it has, independently and without reliance upon the Administrative Agent, any Arranger, any other Lender or any of their respective Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and appraisal of, and investigations into, the business, prospects, operations, property, assets, liabilities, financial and other condition and creditworthiness of the Consolidated Companies and their Subsidiaries, all applicable bank or other regulatory Applicable Laws relating to the Transactions and the transactions contemplated by this Agreement and the other Loan Documents and (e) it has made its own independent decision to enter into this Agreement and the other Loan Documents to which it is a party and to extend credit hereunder and thereunder. Each Lender and each Issuing Lender also acknowledges that (i) it will, independently and without reliance upon the Administrative Agent, any Arranger or any other Lender or any of their respective Related Parties (A) continue to make its own credit analysis, appraisals and decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder based on such documents and information as it shall from time to time deem appropriate and its own independent investigations and (B) continue to make such investigations and inquiries as it deems necessary to inform itself as to the Consolidated Companies and their Subsidiaries and (ii) it will not assert any claim in contravention of this Section 11.7.

SECTION 11.8 No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the syndication agents, documentation agents, co-agents, arrangers or bookrunners listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or an Issuing Lender hereunder, but each such Person shall have the benefit of the indemnities and exculpatory provisions hereof.

SECTION 11.9 Collateral and Guaranty Matters.

(i)Each of the Lenders (including in its or any of its Affiliate’s capacities as a holder of Secured Hedge Obligations and Secured Cash Management Obligations) irrevocably authorize the Administrative Agent:

(1)to release any Lien on any Collateral granted to or held by the Administrative Agent, for the ratable benefit of the Secured Parties, under any Loan Document (A) upon the termination of the Revolving Credit Commitment and payment in full of all Secured Obligations (other than (1) contingent indemnification obligations and (2) Secured Cash Management Obligations or Secured Hedge Obligations) and the expiration or termination of all Letters of Credit (other than Letters of Credit which have been Cash Collateralized or as to which other arrangements satisfactory to the

cxxxvi

165457743_4174358596_2

Administrative Agent and the applicable Issuing Lender shall have been made), (B) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition to a Person other than a Credit Party permitted under the Loan Documents, as certified by Centuri, or (C) if approved, authorized or ratified in writing by the Required Lenders in accordance with Section 12.2; provided that any release of all or substantially of the Collateral shall be subject to Section 12.2(j);

(2)to subordinate any Lien on any Collateral granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien permitted pursuant to Section 9.2(h); provided that the subordination of all or substantially all of the Collateral shall be subject to Section 12.2(j); and

(3)to release any Subsidiary Guarantor from its obligations under any Loan Documents if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents, as certified by Centuri; provided that the release of Subsidiary Guarantors comprising substantially all of the credit support for the Secured Obligations shall be subject to Section 12.2(i).

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Subsidiary Guarantor from its obligations under any Guaranty Agreement pursuant to this Section 11.9. In each case as specified in this Section 11.9, the Administrative Agent will, at the Borrowers’ expense, execute and deliver to the applicable Credit Party such documents as such Credit Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Security Documents or to subordinate its interest in such item, or to release such Subsidiary Guarantor from its obligations under such Guaranty Agreement, in each case in accordance with the terms of the Loan Documents and this Section 11.9. In the case of any such sale, transfer or disposal of any property constituting Collateral in a transaction constituting an Asset Disposition permitted pursuant to Section 9.5 to a Person other than a Credit Party, the Liens created by any of the Security Documents on such property shall be automatically released without need for further action by any person. Notwithstanding anything to the contrary in this Agreement or in any other Loan Document, without the consent of the Required Lenders, no Credit Party shall be released from its obligations under the Loan Documents if such Credit Party ceases to be a Wholly Owned Subsidiary solely by virtue of a disposition or issuance of Equity Interests, unless (x) such disposition or issuance is a good faith disposition or issuance to a bona-fide unaffiliated third party whose primary purpose is not the release of the Guarantee and obligations of such Credit Party under the Loan Documents and (y) the Investment of the Credit Parties in such Subsidiary shall be deemed a de novo Investment as at that time and such Investment shall be permitted under Section 9.3.

(ii)The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any Credit Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

SECTION 11.10 Secured Hedge Agreements and Secured Cash Management Agreements. No Cash Management Bank or Hedge Bank that obtains the benefits of Section 10.4 or any Collateral by virtue of the provisions hereof or of any Security Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Loan Document or otherwise in respect of the Collateral (including the release or impairment of any Collateral), or to notice of or to consent to any amendment, waiver or modification of the provisions hereof or of any Guarantee or any Security Document, other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents. Except as expressly provided in Section 10.4, the Administrative Agent shall not be required to verify the payment of, or that other satisfactory arrangements have been made with respect to, Secured Cash Management Agreements and Secured Hedge Agreements.

SECTION 11.11 Erroneous Payments.

(i)Each Lender, each Issuing Lender, each other Secured Party and any other party hereto hereby severally agrees that if (i) the Administrative Agent notifies (which such notice shall be conclusive absent

cxxxvii

165457743_4174358596_2

manifest error) such Lender or Issuing Lender or any other Secured Party (or the Lender Affiliate of a Secured Party) or any other Person that has received funds from the Administrative Agent or any of its Affiliates, either for its own account or on behalf of a Lender, Issuing Lender or other Secured Party (each such recipient, a “Payment Recipient”) that the Administrative Agent has determined in its reasonable discretion that any funds received by such Payment Recipient were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Payment Recipient) or (ii) any Payment Recipient receives any payment from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, as applicable, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, as applicable, or (z) that such Payment Recipient otherwise becomes aware was transmitted or received in error or by mistake (in whole or in part) then, in each case, (A) an error in payment shall be presumed to have been made (any such amounts specified in clauses (i) or (ii) of this Section 11.11(a), whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise; individually and collectively, an “Erroneous Payment”), and (B) such Payment Recipient is deemed to have knowledge of such error at the time of its receipt of such Erroneous Payment; provided that nothing in this Section shall require the Administrative Agent to provide any of the notices specified in clauses (i) or (ii) above. Each Payment Recipient agrees that it shall not assert any right or claim to any Erroneous Payment, and hereby waives any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payments, including without limitation waiver of any defense based on “discharge for value” or any similar doctrine.

(ii)Without limiting the immediately preceding clause (a), each Payment Recipient agrees that, in the case of clause (a)(ii) above, it shall promptly notify the Administrative Agent in writing of such occurrence.

(iii)In the case of either clause (a)(i) or (a)(ii) above, such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and upon demand from the Administrative Agent such Payment Recipient shall (or, shall cause any Person who received any portion of an Erroneous Payment on its behalf to), promptly, but in all events no later than two Business Days thereafter (or such later date as the Administrative Agent may, in its sole discretion, specify in writing), return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made in Same Day Funds and in the currency so received, together with interest thereon (except to the extent waived in writing by the Administrative Agent) in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent at the Overnight Rate.

(iv)In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with immediately preceding clause (c), from any Lender that is a Payment Recipient or an Affiliate of a Payment Recipient (such unrecovered amount as to such Lender, an “Erroneous Payment Return Deficiency”), then at the sole discretion of the Administrative Agent and upon the Administrative Agent’s written notice to such Lender (i) such Lender shall be deemed to have made a cashless assignment of the full face amount of the portion of its Loans (but not its Commitments) of the relevant Class with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) to the Administrative Agent or, at the option of the Administrative Agent, the Administrative Agent’s applicable lending affiliate in an amount that is equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment”) plus any accrued and unpaid interest on such assigned amount, without further consent or approval of any party hereto and without any payment by the Administrative Agent or its applicable lending affiliate as the assignee of such Erroneous Payment Deficiency Assignment. Without limitation of its rights hereunder, the Administrative Agent may cancel any Erroneous Payment Deficiency Assignment at any time by written notice to the applicable assigning Lender and upon such revocation all of the Loans assigned pursuant to such Erroneous Payment Deficiency Assignment shall be reassigned to such Lender without any requirement for payment or other consideration. The parties hereto acknowledge and agree that (1) any assignment contemplated in this clause (d) shall be

cxxxviii

165457743_4174358596_2

made without any requirement for any payment or other consideration paid by the applicable assignee or received by the assignor, (2) the provisions of this clause (d) shall govern in the event of any conflict with the terms and conditions of Section 12.9 and (3) the Administrative Agent may reflect such assignments in the Register without further consent or action by any other Person.

(v)Each party hereto hereby agrees that (x) in the event an Erroneous Payment (or portion thereof) is not recovered from any Payment Recipient that has received such Erroneous Payment (or portion thereof) for any reason, the Administrative Agent (1) shall be subrogated to all the rights of such Payment Recipient with respect to such amount and (2) is authorized to set off, net and apply any and all amounts at any time owing to such Payment Recipient under any Loan Document, or otherwise payable or distributable by the Administrative Agent to such Payment Recipient from any source, against any amount due to the Administrative Agent under this Section 11.11 or under the indemnification provisions of this Agreement, (y) the receipt of an Erroneous Payment by a Payment Recipient shall not for the purpose of this Agreement be treated as a payment, prepayment, repayment, discharge or other satisfaction of any Obligations owed by the Borrowers or any other Credit Party, except, in each case, to the extent such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrowers or any other Credit Party for the purpose of making for a payment on the Obligations and (z) to the extent that an Erroneous Payment was in any way or at any time credited as payment or satisfaction of any of the Obligations, the Obligations or any part thereof that were so credited, and all rights of the Payment Recipient, as the case may be, shall be reinstated and continue in full force and effect as if such payment or satisfaction had never been received.

(vi)Each party’s obligations under this Section 11.11 shall survive the resignation or replacement of the Administrative Agent or any transfer of right or obligations by, or the replacement of, a Lender, the termination of the Commitments or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Loan Document.

(vii)Nothing in this Section 11.11 will constitute a waiver or release of any claim of any party hereunder arising from any Payment Recipient’s receipt of an Erroneous Payment.

(v)change Section 5.6 or Section 10.4 in a manner that would alter the pro rata sharing of payments or order of application required thereby without the written consent of each Lender directly and adversely affected thereby;

cxlii

165457743_4174358596_2

11.9(a)(i)(C)) or as otherwise specifically permitted or contemplated in this Agreement or the applicable Security Document) without the written consent of each Lender;

(iii)Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrowers, shall maintain at one of its offices in Charlotte, North Carolina, a copy of each Assignment and Assumption and each Incremental Amendment delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amounts of (and stated interest on) the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, absent manifest error, and the Borrowers, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers and any Lender (but only to the extent of entries in the Register that are applicable to such Lender), at any reasonable time and from time to time upon reasonable prior notice.

(iv)Participations. Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to any Person (other than a natural Person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person)

cxlix

165457743_4174358596_2

or any Borrower or any of the Borrowers’ Subsidiaries or Affiliates) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers, the Administrative Agent, the Issuing Lenders, the Swingline Lenders and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Xxxxxx’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 12.3(c) with respect to any payments made by such Lender to its Participant(s).

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 12.2(b), (c), (d) or (e) that directly and adversely affects such Participant. The Borrowers agree that each Participant shall be entitled to the benefits of Sections 5.9, 5.10 and 5.11 (subject to the requirements and limitations therein, including the requirements under Section 5.11(g) (it being understood that the documentation required under Section 5.11(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 5.12 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 5.10 or 5.11, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrowers’ request and expense, to use reasonable efforts to cooperate with the Borrowers to effectuate the provisions of Section 5.12(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.4 as though it were a Lender; provided that such Participant agrees to be subject to Section 5.6 and Section 12. 4 as though it were a Lender.

Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrowers, maintain a register on which it enters the name and address of each Participant and the principal amounts of (and stated interest on) each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

Except as provided in Section 6.1, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or in electronic (i.e., “pdf” or “tif”) format shall be effective as delivery of a manually executed counterpart of this Agreement.

(ii)Electronic Execution. The words “execute,” “execution,” “signed,” “signature,” “delivery” and words of like import in or related to this Agreement, any other Loan Document or any document, amendment, approval, consent, waiver, modification, information, notice, certificate, report, statement, disclosure, or authorization to be signed or delivered in connection with this Agreement or any other Loan Document or the transactions contemplated hereby shall be deemed to include Electronic Signatures or execution in the form of an Electronic Record, and contract formations on electronic platforms approved by the Administrative Agent, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any Applicable Law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. Each party hereto agrees that any Electronic Signature or execution in the form of an Electronic Record shall be valid and binding on itself and each of the other parties hereto to the same extent as a manual, original signature. For the avoidance of doubt, the authorization under this paragraph may include, without limitation, use or acceptance by the parties of a manually signed paper which has been converted into electronic form (such as scanned into PDF format), or an electronically signed paper converted into another format, for transmission, delivery and/or retention. Notwithstanding anything contained herein to the contrary, the Administrative Agent is under no obligation to accept an Electronic Signature in any form or in any format unless expressly agreed to by the Administrative Agent pursuant to procedures approved by it; provided that without limiting the foregoing, (i) to the extent the Administrative Agent has agreed to accept such Electronic Signature from any party hereto, the Administrative Agent and the other parties hereto shall be entitled to rely on any such Electronic Signature purportedly given by or on behalf of the executing party without further verification and (ii) upon the request of the Administrative Agent or any Lender, any Electronic Signature shall be promptly followed by an original manually executed counterpart thereof. Without limiting the generality of the foregoing, each party hereto hereby (A) agrees
