Agreement (as of the date hereof) are proportionate to each Lender’s Applicable Percentage, after giving effect to the reallocation of the Commitment amounts of the Lenders. 

ARTICLE XI For purposes of determining withholding Taxes under FATCA, from and after the Amendment No. 4 Effective
Date, the Borrower and the Administrative Agent shall treat (and the Lenders hereby authorize the Administrative Agent to treat) the Credit Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury

 REVOLVING CREDIT AGREEMENT, dated as of March 15, 2012, among
SOUTHWEST GAS CORPORATION, a California corporation (the “Borrower”), each of the lenders from time to time parties to this Agreement (collectively, the “Lenders”), and THE BANK OF NEW YORK MELLON, as Administrative
Agent (the “Administrative Agent”). 
 WITNESSETH: 

WHEREAS, the Borrower has requested the Lenders severally to commit to lend to the Borrower up to $400,000,000 on a revolving
basis for repayment of all amounts outstanding under the Existing Credit Agreement (as defined below), to fund fees and expenses associated with this Agreement (as defined below) and for general corporate purposes; and 

WHEREAS, the Lenders are willing to make such loans, on the terms and conditions provided herein; 

NOW, THEREFORE, the parties agree as follows: 

ARTICLE XII 

DEFINITIONS 

Section 12.01 Definitions. 

(a)       Terms Generally. The definitions ascribed to terms in this Agreement apply
equally to both the singular and plural forms of such terms. Whenever the context may require, any pronoun shall be deemed to include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and
“including” shall be interpreted as if followed by the phrase “without limitation”. The phrase “individually or in the aggregate” shall be deemed general in scope and not to refer to any specific Section or clause of
this Agreement. All references herein to Articles, Sections, Exhibits and Schedules shall be deemed references to Articles and Sections of, and Exhibits and Schedules to, this Agreement unless the context shall otherwise require. The table of
contents, headings and captions herein shall not be given effect in interpreting or construing the provisions of this Agreement. Except as otherwise expressly provided herein, all references to “dollars” or “$” shall be deemed
references to the lawful money of the United States of America. 

(b)       Accounting Terms. Except as otherwise expressly provided herein, the term
“consolidated” and all other terms of an accounting nature shall be interpreted and construed in accordance with GAAP, as in effect from time to time; provided, however, that, for purposes of determining compliance with any
covenant set forth in Article VII, such terms shall be construed in accordance with GAAP as in effect on the date of this Agreement, applied on a basis consistent with the construction thereof applied in preparing

 
the Borrower’s audited financial statements referred to in Section 5.01(k). If there shall occur a change in GAAP which but for the foregoing proviso would affect the computation used to
determine compliance with any covenant set forth in Article VII, the Borrower and the Lenders agree to negotiate in good faith in an effort to agree upon an amendment to this Agreement that will permit compliance with such covenant to be determined
by reference to GAAP as so changed while affording the Lenders the protection intended to be afforded by such covenant prior to such change (it being understood, however, that such covenant shall remain in full force and effect in accordance with
its existing terms unless and until such amendment shall become effective). 

(c)       Other Terms. The following terms have the meanings ascribed to them below
or in the Sections of this Agreement indicated below: 
 “ABR Loans” means Loans that bear interest at a
rate or rates determined by reference to the Alternate Base Rate.

“Act” has the meaning assigned to such term in Section 11.12. 

“Administrative Agent” means The Bank of New York Mellon, acting in the capacity of administrative agent for
the Lenders, or any successor administrative agent appointed pursuant to the terms of this Agreement.

“Affiliate” means, when used with reference to any Person, a Person (other than a Subsidiary) which directly
or indirectly controls, is controlled by, or is under common control with, such other Person. For purposes of this definition, “control” (including with correlative meanings, the terms “controlling,” “controlled by” and
“under common control with”) as applied to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of that Person, whether through the ownership of voting
securities or by contract or otherwise. 
 “Agreement” means this Revolving Credit Agreement, as it may be
amended, modified or supplemented from time to time. 
 “Alternate Base Rate” means, for any day, a rate
per annum equal to the greatest of: 

  
 2

of interest from time to time publicly announced by the Administrative Agent as its prime commercial loan rate in effect on such day; 

(ii)        the sum of (a) 1/2 of 1% per annum and (b) the
Federal Funds Effective Rate in effect on such day; and 

(iii)       the sum of (a) 1% per annum and (b) the One Month LIBOR

Borrowing Date). 
 Section 13.02 Borrowing Procedure. 

In order to borrow Loans, the Borrower shall give a Borrowing Request to the Administrative Agent not later than 12:00 noon,
New York time, (i) on the Borrowing Date for ABR Loans and (ii) on the third Business Day before the Borrowing Date for Eurodollar Loans. Upon receipt, the Administrative Agent forthwith shall give notice to each Lender of the substance of

Commitment, or reduce the amount thereof, by (i) giving written notice to the Administrative Agent, not later than 5:00 P.M., New York time, on the fifth Business Day prior to the date of termination or reduction and (ii) paying the amount
of the Commitment Fees accrued through such date of termination or reduction. Reductions of the Total Commitment shall be in the amount of $5,000,000 or in integral multiples of $1,000,000 in excess thereof (or, if the amount of the Available

permanent. 
 (c)       The Borrower may from time to time, at its sole expense and
effort after consulting with the Administrative Agent, request: (i) one or more Lenders to increase (in the sole and absolute discretion of each such Lender) the amount of their respective Commitments and/or (ii) one or more other lending
institutions reasonably acceptable to the Administrative Agent (each, a “New Lender”) to become “Lenders” and extend Commitments hereunder (each such Lender and each New Lender being herein referred to as a
“Proposed Lender”). To request an increase pursuant to this Section 2.03(c), the Borrower shall submit to the Administrative Agent an Increase Request, in the form annexed hereto as Exhibit G, signed by the Borrower, which
shall be irrevocable and shall specify, as the case may be: (A) each such Lender and the amount of the proposed increase in its Commitment, or (B) the proposed Commitment for such New Lender. Promptly following receipt of an Increase
Request, the Administrative Agent shall advise each Lender of the details thereof. If one or more of such Proposed Lenders shall have unconditionally agreed to such Increase Request in a writing delivered to the Borrower and the Administrative Agent
(each such existing Lender and New Lender being hereinafter referred to as an “Incremental Lender”), then: (1) each such Incremental Lender which shall then be an existing Lender shall have its Commitment increased by the
amount set forth in such Increase Request, and (2) each such New Lender shall be and become a “Lender” hereunder having a Commitment equal to the amount set forth therefor in such Increase Request, provided, however, that in
each such case: (I) immediately before and after giving effect thereto, no Default or Event of Default shall or would exist, (II) each such Incremental Lender shall have executed and delivered to the Administrative Agent a supplement to
this Agreement, in the form annexed hereto as Exhibit I, providing for its increased Commitment or its Commitment, as applicable, in form approved by the Administrative Agent, (III) immediately after giving effect thereto, the Total
Commitment under this Agreement shall not exceed $500,000,000, (IV) each such Increase Request shall be in an aggregate minimum amount of $10,000,000 or an integral multiple of $5,000,000 in excess thereof, and (V) the Commitment extended by
any such Incremental Lender which is a New Lender shall be in a minimum amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof. 

(d)       Simultaneously with each increase in the aggregate amount of the Commitments
under Section 2.03(c), each Incremental Lender shall, to the extent necessary, purchase from each other Lender, and each other Lender shall sell to each 

  
 24 

 
Incremental Lender, in each case at par and without representation, warranty, or recourse (in accordance with and subject to the restrictions contained in Section 10.03), such principal
amount of the Loans of such other Lender, together with all accrued and unpaid interest thereon, as will result, after giving effect to such transaction, in each Lender’s Applicable Percentage of Loans outstanding being equal to such
Lender’s Applicable Percentage of all Loans, provided that each such assignor Lender shall have received (to the extent of the interests, rights and obligations assigned) payment of the outstanding principal amount of such Loans, accrued
interest thereon, accrued fees, commissions and all other amounts payable to it under the Credit Documents from the applicable assignee Lenders (to the extent of such outstanding principal and accrued interest, fees and commissions) or the Borrower
(in the case of all other amounts). 
 (e)       The Borrower may, by written notice to
the Administrative Agent (which shall promptly deliver a copy to each of the Lenders) not less than 30 days and not more than 90 days prior to the first, second, third, fourth and/or fifth anniversary of the Amendment No. 4 Effective Date, an
Extension Request, in the form annexed hereto as Exhibit H, signed by the Borrower, request that the Lenders extend the Termination Date then in effect and the Commitments for an additional period of one year. Each Lender shall, by notice to
the Borrower and the Administrative Agent given not later than the 15th day after the date of the Administrative Agent’s receipt of the Borrower’s extension request, advise the Borrower whether or not it agrees to the requested extension
(each Lender agreeing to a requested extension being called a “Consenting Lender” and each Lender declining to agree to a requested extension being called a “Declining Lender”). Any Lender that has not so advised
the Borrower and the Administrative Agent by such day shall be deemed to have declined to agree to such extension and shall be a Declining Lender. If Lenders constituting the Required Lenders shall have agreed to an extension request in their sole
and absolute discretion, then the Termination Date shall, as to the Consenting Lenders, be extended to the first anniversary of the Termination Date theretofore in effect. The decision to agree or withhold agreement to any Termination Date extension
shall be at the sole discretion of each Lender. The Commitment of any Declining Lender shall terminate on the Termination Date in effect prior to giving effect to any such extension (such Termination Date being called the “Existing
Termination Date”). Notwithstanding the foregoing provisions of this Section 2.03(e), the Borrower shall have the right, with the prior written consent (not to be unreasonably withheld) of the Administrative Agent, at any time prior to the
Existing Termination Date, to replace a Declining Lender with a Lender or Eligible Institution that will agree to a request for the extension of the Termination Date then in effect, and any such Replacement Lender shall for all purposes constitute a
Consenting Lender, provided, however, that in each such case (i) each such Replacement Lender shall have executed and delivered to the Administrative Agent a supplement to this Agreement, in the form annexed hereto as Exhibit J,
providing for its Commitment, and (ii) the Declining Lender shall assign, in accordance with Section 10.03(a), all or part, as the case may be, of its Loans, Commitment, Revolving Credit Note and other rights and obligations under this
Agreement and all other Credit Documents to such Replacement Lender, in exchange for payment of the principal of, and interest 

  
 25 

 
accrued to the date of such payment on, Loans owing to such Declining Lender and any accrued Commitment Fees owing to such Declining Lender; and upon such payments, the obligations of such
Declining Lender hereunder in respect of its Commitment shall, by the provisions hereof, be released and discharged and such Replacement Lender shall be and become a “Lender” hereunder having a Commitment equal to the amount set forth
therefor in such supplement. Notwithstanding the foregoing, no extension of the Termination Date pursuant to this paragraph shall become effective unless (i) the Administrative Agent shall have received documents consistent with those delivered
with respect to the Lender under Section 6.01(c), (d), (e)(ii) (it being understood and agreed that the date referred to in Section 6.01(e)(ii) shall refer to the date of the then most recently delivered audited financial statements required to be
delivered pursuant to Section 7.01(a)(i)), (e)(iii), (e)(iv) and (e)(v), giving effect to such extension and (ii) on the date on which the Required Lenders shall have agreed to an extension request, (A) the conditions set forth in Section
6.02(b) shall be satisfied and (B) the representations and warranties contained in Section 5.01 shall be true and correct in all material respects (except to the extent that any representation or warranty speaks as of a date certain),
except for any representation or warranty that is qualified by materiality or reference to Material Adverse Effect (in which case such representation or warranty shall be true and correct in all respects), and the Administrative Agent shall have
received a certificate with respect to the matters referred to in clauses (A) and (B) dated such date and executed by a Responsible Officer. Unless a Declining Lender ceases to be a Lender hereunder pursuant to the above provisions in this
Section 2.03(e), the Borrower hereby agrees to pay to the Administrative Agent in accordance with the terms of this Agreement, for distribution to the Declining Lenders, all of the outstanding Loans made by the Declining Lenders, together with all
accrued and unpaid interest thereon and all accrued fees and other amounts payable to or for the accounts of the Declining Lenders on the Existing Termination Date, and, upon each Declining Lender’s receipt of such amounts, such Declining
Lender shall cease to be a Lender hereunder. 
 Section 13.04 Repayment. 

All Loans shall be repaid, together with all accrued and unpaid interest thereon, on the Termination Date. 

Section 13.05 Optional Prepayment. 

The Borrower may prepay Loans bearing interest on the same basis and having the same Interest Periods, if any, by giving
notice to the Administrative Agent not later than 1:00 P.M., New York time, on the third Business Day preceding the proposed date of prepayment, in the case of Eurodollar Loans, or not later than 1:00 P.M., New York time, on the Business Day of the
proposed prepayment, in the case of ABR Loans. Each such prepayment of Eurodollar Loans shall be in an aggregate principal amount of $5,000,000 or in integral multiples of $1,000,000 in excess thereof (or, if the aggregate amount of outstanding
Eurodollar Loans is less than $5,000,000, then all of such lesser amount), and 

  
 26 

 
each prepayment of ABR Loans shall be in an aggregate amount of $1,000,000 or in integral multiples of $100,000 in excess thereof (or, if the aggregate amount of outstanding ABR Loans is less

conditions of this Agreement, prepaid Loans may be reborrowed.

(i)        Commitment Fees shall cease to accrue on the Commitment of such Defaulting
Lender pursuant to Section 3.07; 
 (ii)        the Commitment and Loans of
such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 11.06); provided that any
waiver, amendment or modification that would (A) increase the Commitment of such Defaulting Lender or subject such Defaulting Lender to any additional obligations, (B) reduce the principal of, or interest on, the Loans made by such
Defaulting Lender or (C) postpone any date fixed for any payment of principal of, or interest on, the Loans made by such Defaulting Lender (which, for avoidance of doubt, shall not include forbearing from exercising remedies as a result
thereof), shall require the consent of such Defaulting Lender; and 

(iii)        any amount payable to such Defaulting Lender hereunder (whether on
account of principal, interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Lender) shall, in lieu of being distributed to such Defaulting Lender, be retained by the Administrative Agent in a
segregated account and, subject to any applicable requirements of law, be applied at such time or times as may be determined by the Administrative Agent, in the following order of priority: (A) first, to the payment of any amounts owing by such
Defaulting Lender to the Administrative Agent hereunder, (B) second, as the Borrower may request (so long as no Default or Event of Default exists) to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its

Days’ notice in writing to the Administrative Agent and a Defaulting Lender, (i) request such Defaulting Lender to cooperate with the Borrower in obtaining a Replacement Lender for such Defaulting Lender; (ii) request the non-Defaulting Lenders to acquire and assume all or a portion of such Defaulting Lender’s Loans and Commitment, but none of such Lenders shall be obligated to do so; or (iii) propose a Replacement Lender.
If a Replacement Lender shall be accepted by the Administrative Agent or one or more of the non-Defaulting Lenders shall agree to acquire and assume all or part of a Defaulting Lender’s Loans and
Commitment, then such Defaulting Lender shall assign, in accordance with Section 10.03(a), all or part, as the case may be, of its Loans, Commitment, Revolving Credit Note and other rights and obligations under this Agreement and all other Credit
Documents to such Replacement Lender or non-Defaulting Lenders, as the case may be, in exchange for payment of the principal of, and interest accrued to the date of such payment on, Loans owing to such
Defaulting Lender and any accrued Commitment Fees owing to such Defaulting Lender; and upon such payments, the obligations of such Defaulting Lender hereunder in respect of its Commitment shall, by the provisions hereof, be released and discharged;
provided, however, that such Defaulting Lender’s rights under Sections 4.03, 4.04 and 4.06, and its obligations under Section 9.06 shall survive such release and discharge as to matters occurring prior to such date;
provided further, however, that such assignment shall be on the terms and conditions set forth in Section 10.03(a). If the Replacement Lender and the non-Defaulting Lenders shall only be
willing to acquire less than all of a Defaulting Lender’s outstanding Loans and Commitment, the Commitment of such Defaulting Lender shall not terminate, but shall be reduced proportionately, and such Defaulting Lender shall continue to be a
“Lender” hereunder with a reduced Commitment and Pro Rata Share. Upon the effective date of such assignment, such Replacement Lender shall, if not already a Lender, become a “Lender” for all purposes under this Agreement and the
other Credit Documents. 
 (c)       The rights and remedies against a Defaulting Lender
under this Section 2.06 are in addition to other rights and remedies that the Borrower, the Administrative Agent or any Lender may have against such Defaulting Lender. 

(d)       In the event that the Administrative Agent and the Borrower agree that a
Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in
order for such Lender to hold such Loans ratably in accordance with its Commitments and such Lender shall no longer 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 Borrower while that Lender 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 Lender’s having been a Defaulting Lender.

 ARTICLE XIV 

INTEREST AND FEES 

Section 14.01 Interest Rate Determination; Conversion. 

(a)       Except to the extent that the Borrower shall request, in a Borrowing Request, in
a Conversion Request or in a written election pursuant to Section 3.03(b), that Loans (or portions thereof) bear interest as Eurodollar Loans, Loans shall bear interest as ABR Loans. 

(b)       The Borrower may request, by giving a Conversion Request to the Administrative
Agent, not later than 1:00 P.M., New York time, on the third Business Day prior to the requested Conversion Date, that all or portions of the outstanding Loans, in the aggregate principal amount of $5,000,000 or in integral multiples of $1,000,000
in excess thereof, in the case of Loans being converted to or continued as Eurodollar Loans, and in the aggregate principal amount of $1,000,000 or in integral multiples of $100,000 in excess thereof (or, if the aggregate principal amount of
outstanding Loans is less than $1,000,000, then all such lesser amount), in the case of ABR Loans, bear interest from and after the Conversion Date as either ABR Loans or Eurodollar Loans; provided, however, that during the continuance
of any Default or Event of Default that shall have occurred, no Loan (or portion thereof) may be converted into Eurodollar Loans. Upon receipt, the Administrative Agent forthwith shall give notice to each Lender of the substance of each Conversion
Request. Upon payment by the Borrower of the amounts, if any, required by Section 4.03, on the Conversion Date the Loans or portions thereof as to which the Conversion Request was made shall commence to accrue interest in the manner selected by
the Borrower therein. 
 Section 14.02 Interest on ABR Loans. 

Each ABR Loan shall bear interest from the date made until the date repaid, or (if converted into a Eurodollar Loan) to (but
excluding) the first day of any relevant Interest Period, as the case may be, payable in arrears on the last day of each calendar quarter of each year, commencing with the first such date after the Effective Date, and on the date such Loan is
repaid, at a rate per annum equal to the sum of (i) the Applicable Margin and (ii) the Alternate Base Rate in effect from time to time, which rate shall change as and when said Applicable Margin or Alternate Base Rate shall change. 

Section 14.03 Interest on Eurodollar Loans. 

(a)       Each Eurodollar Loan shall bear interest from the date made until the date repaid
or converted to an ABR Loan, payable in arrears, with respect to Interest Periods of three months or less, on the last day of such Interest Period, and with respect to Interest Periods longer than three months, the respective dates that fall every
three months after the commencement of such Interest Period and on the last day of such Interest Period, at a rate 

  
 29 

 
per annum equal to the sum of (i) the Applicable Margin and (ii) the LIBOR rate for such Interest Period. 

(b)       Each Eurodollar Loan shall become an ABR Loan at the end of the Interest Period
therefor, unless (i) there shall not have occurred and be continuing a Default or Event of Default and (ii) not later than the third Business Day prior to the last day of such Interest Period, (x) the Borrower shall have delivered to
the Administrative Agent an irrevocable written election of the subsequent Interest Period, in which case such Eurodollar Loan shall remain outstanding as a Eurodollar Loan, or (y) the Borrower shall have delivered to the Administrative Agent a
Conversion Request with respect thereto, in which case such Eurodollar Loan shall be converted in accordance with Section 3.01(b). 

(c)       If, during any period, a Lender shall be required to maintain reserves against
“Eurocurrency Liabilities” in accordance with Federal Reserve Board Regulation D (or any successor regulation), the Borrower shall pay additional interest during such period on each outstanding Eurodollar Loan of such Lender
(contemporaneously with each interest payment due thereon commencing with the first such payment due at least five Business Days after receipt of the notice referred to in the next sentence) at a rate per annum up to but not exceeding the marginal
rate determined by the following formula: 
  

			
	                        LIBOR           
             	  	- LIBOR
	l -Eurodollar Reserve Percentage	  	

 Each Lender shall promptly notify the Borrower, with a copy to the Administrative Agent, upon becoming aware
that the Borrower may be required to make a payment of additional interest to such Lender. When requesting payment pursuant to this Section 3.03(c), a Lender shall provide to the Borrower, with a copy to the Administrative Agent, a
certificate, signed by an officer of such Lender setting forth, in reasonable detail, the basis of such claim, the amount required to be paid by the Borrower to such Lender and the computations made by such Lender to determine such amount. Absent
demonstrable error, such certificate shall be binding as to the amounts of additional interest owing in respect of such Lender’s Eurodollar Loans. Any Lender that gives notice under this Section 3.03(c) shall promptly withdraw such notice (by
written notice of withdrawal given to the Administrative Agent and the Borrower) whenever such Lender is no longer required to maintain such reserves or the circumstances giving rise to such notice shall otherwise cease. 

Section 14.04 Interest on Overdue Amounts. 

All overdue amounts (including principal, interest and fees) hereunder shall bear interest, payable on demand, at a rate per
annum equal to the sum of (i) 2% and (ii) in the case of Eurodollar Loans, the rate then applicable until the end of the current Interest Period therefor, and thereafter the rate of interest applicable to ABR Loans, changing as and when such
rate shall change, and in the case of ABR Loans, the rate of interest applicable thereto, changing as and when such rate shall change. 

  
 30 

 Section 14.05 Day Counts. 

Interest on ABR Loans shall be calculated on the basis of (a) a 365- or, if
applicable, a 366-day year for the actual number of days elapsed for so long as interest is determined pursuant to clause (i) of the definition of “Alternate Base Rate” and (b) a 360-day year for the actual number of days elapsed for so long as interest is determined based on clause (ii) or clause (iii) of the definition of “Alternate Base Rate”. Interest on all other
Loans, and all fees shall be calculated on the basis of a 360-day year for the actual number of days elapsed. 

Section 14.06 Maximum Interest Rate. 

(a)       Nothing in this Agreement shall require the Borrower to pay interest at a rate
exceeding the maximum rate permitted by applicable law. Neither this Section nor Section 11.01 is intended to limit the rate of interest payable for the account of any Lender to the maximum rate permitted by the laws of the State of New York
(or any other applicable law) if a higher rate is permitted with respect to such Lender by supervening provisions of U.S. Federal law. 

(b)       If the amount of interest payable for the account of any Lender on any interest
payment date in respect of the immediately preceding interest computation period, computed pursuant to this Article III, would exceed the maximum amount permitted by applicable law to be charged by such Lender, the amount of interest payable for its
account on such interest payment date shall automatically be reduced to such maximum permissible amount. 

(c)       If the amount of interest payable for the account of any Lender in respect of any
interest computation period is reduced pursuant to Section 3.06(b) and the amount of interest payable for its account in respect of any subsequent interest computation period would be less than the maximum amount permitted by law to be charged by
such Lender, then the amount of interest payable for its account in respect of such subsequent interest computation period shall be automatically increased to such maximum permissible amount; provided that at no time shall the aggregate
amount by which interest paid for the account of any Lender has been increased pursuant to this Section 3.06(c) exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to Section 3.06(b). 

Section 14.07 Commitment Fees. 

The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, on the last day of each calendar
quarter of each year, commencing with the first such day after the Effective Date (or such later date on which such Lender becomes a Lender), and on the Termination Date (or other date on which the Commitment shall terminate) with respect to such
Lender, a fee (the “Commitment Fee”) computed by applying (i) on each day on which the applicable Pricing Level set forth below is in effect, 

  
 31 

 
the percentage per annum set forth below adjacent to such Pricing Level on such day during the then-ending quarter (or shorter period ending with the
Termination Date or any other date on which the Commitment of such Lender shall terminate) to (ii) the amount of such Lender’s Unused Commitment on such day:

 ARTICLE XV 

DISBURSEMENT AND PAYMENT 

Section 15.01  Disbursement. 

(a)       Each Loan shall be made by the relevant Lender from such Lender’s branch or
affiliate identified as its Applicable Lending Office. 
 (b)       The failure of any
Lender to make any Loan to be made by it on the Borrowing Date therefor shall not relieve any other Lender of its obligation to make its Loan or Loans on such date, but neither any Lender nor the Administrative Agent shall be responsible for the
failure of any other Lender to make a Loan to be made by such other Lender. 

(c)       The Administrative Agent may, but shall not be required to, advance on behalf of
any Lender the amount of such Lender’s Loan to be made on a Borrowing Date, unless such Lender shall have notified the Administrative Agent prior to such Borrowing Date that it does not intend to make such Loan on such date. If the
Administrative Agent makes any such advance, the Administrative Agent shall be entitled to recover the amount so advanced on demand from the Lender on whose behalf such advance was made and, if such Lender does not pay the Administrative Agent the
amount of such advance on demand, the Borrower agrees promptly to repay such amount to the Administrative Agent. 

  
 32 

 
Until such amount is repaid to the Administrative Agent by such Lender or the Borrower, such advance shall be deemed for all purposes to be a Loan made on such Borrowing Date by the
Administrative Agent. The Administrative Agent shall be entitled to recover from the Lender or the Borrower, as the case may be, interest on the amount advanced by it for each day from the Borrowing Date therefor until repaid to the Administrative
Agent, at a rate per annum equal to the Federal Funds Effective Rate until the third Business Day after the date of the advance and, thereafter, at the rate per annum equal to the relevant rate on Loans made on the relevant Borrowing Date. 

Section 15.02  Method and Time of Payments; Sharing among Lenders. 

(a)       All funds received by the Administrative Agent for the account of the Lenders in
respect of payments made by the Borrower under, or from any other Person on account of, any Credit Document shall be distributed forthwith by the Administrative Agent among the Lenders, in like funds as received, ratably in proportion to their
respective interests therein. Each payment of Commitment Fees and each reduction of the Total Commitment shall be apportioned among the Lenders in proportion to each Lender’s Pro Rata Share. 

(b)       All payments by the Borrower hereunder shall be made without setoff or
counterclaim to the Administrative Agent, for its account or for the account of the Lender or Lenders entitled thereto, as the case may be, in dollars and in immediately available funds at the office of the Administrative Agent prior to 3:00 P.M.,
New York time, on the date when due; provided, however, that the Borrower shall have setoff rights with respect to any Defaulting Lender with the application of any amounts payable to a Defaulting Lender to be administered by the Administrative
Agent pursuant to Section 2.06(a)(iii). 
 (c)       Whenever any payment from the
Borrower shall be due on a day that is not a Business Day, the date of payment thereof shall be extended to the next succeeding Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon
shall be payable for such extended time. 
 (d)       Unless the Administrative Agent
shall have received notice from the Borrower prior to the date on which any payment from the Borrower is due that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to
the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, but shall not be obligated to, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If
and to the extent that the Borrower shall not have so made such payment, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such
amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Effective Rate. 

  
 33 

 (e)       If any Lender shall receive from the
Borrower or any other Person any amount owing under any Credit Document (whether received pursuant to the exercise of any right of set-off, banker’s lien, realization upon any security held for or
appropriated to such obligation or otherwise) other than in proportion to such Lender’s ratable share thereof, then such Lender shall purchase from each other Lender a participating interest in so much of the other Lenders’ Loans as shall
be necessary in order that each Lender shall share such payment with each of the other Lenders in proportion to each Lender’s ratable share; provided that nothing herein contained shall obligate any Lender to apply any set-off, banker’s lien or collateral security first to the obligations of the Borrower hereunder if the Borrower is obligated to such Lender pursuant to other loans or notes. If any purchasing Lender shall be
required to return any excess payment received by it, such participation shall be rescinded and the purchase price restored to the extent of such return, but without interest. 

Section 15.03  Compensation for Losses. 

(a)       If (i) the Borrower makes a prepayment, or a Conversion Date occurs, other
than on the last day of the relevant Interest Period, (ii) the Borrower fails to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, (iii) the Borrower revokes any
Borrowing Request for Eurodollar Loans, (iv) Eurodollar Loans (or portions thereof) are converted into ABR Loans pursuant to Section 4.05 at any time other than at the end of an Interest Period or (v) Loans (or portions thereof) shall
become or be declared to be due prior to the scheduled maturity thereof, then the Borrower shall pay to each Lender an amount that will compensate such Lender for any loss (other than lost profit) or premium or penalty incurred by such Lender as a
result of such prepayment, conversion, declaration or revocation in respect of funds obtained for the purpose of making or maintaining such Lender’s Eurodollar Loans, or any portion thereof. Such compensation shall include an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on the amount so paid or prepaid, or not borrowed or converted, for the period from the date of such payment or prepayment or conversion or failure to borrow to the last
day of such Interest Period (or, in the case of a failure to borrow, the Interest Period that would have commenced on the date of such failure to borrow) in each case at the applicable rate of interest for such Eurodollar Loan provided for herein
(excluding, however, any Applicable Margin included therein) over (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the London interbank deposit market. 
 (b)       In
connection with a demand for payment pursuant to this Section 4.03, a Lender shall provide to the Borrower, with a copy to the Administrative Agent, a certificate, signed by an officer of such Lender, setting forth in reasonable detail the
amount required to be paid by the Borrower to such Lender and the computations made by 

  
 34 

 
such Lender to determine such amount. In the absence of demonstrable error, such certificate shall be conclusive as to the amount so required to be paid. 

Section 15.04  Withholding and Additional Costs. 

(a)       Withholding. (i) To the extent permitted by law, all payments under
this Agreement and under the Revolving Credit Notes (including payments of principal and interest) shall be payable to each Lender free and clear of any and all present and future taxes, levies, imposts, duties, deductions, withholdings, fees,
liabilities and similar charges other than Excluded Taxes (collectively, “Taxes”). If any Taxes are required to be withheld or deducted from any amount payable under this Agreement, then the amount payable under this Agreement shall
be increased to the amount which, after deduction from such increased amount of all Taxes required to be withheld or deducted therefrom, will yield to such Lender the amount stated to be payable under this Agreement. The Borrower shall also hold
each Lender harmless and indemnify it for any stamp or other taxes with respect to the preparation, execution, delivery, recording, performance or enforcement of the Credit Documents (all of which shall be included within “Taxes”). If any
of the Taxes specified in this Section 4.04(a) are paid by any Lender, the Borrower shall, upon demand of such Lender, promptly reimburse such Lender for such payments, together with any interest, penalties and expenses incurred in connection
therewith; provided, however, that the Borrower shall not be required to reimburse any Lender for any penalties incurred or caused by the failure or delay on the part of such Lender to pay any of the Taxes specified in this Section
4.04(a). The Borrower shall deliver to the Administrative Agent certificates or other valid vouchers for all Taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder. Notwithstanding the foregoing, the
Borrower shall be entitled, to the extent required to do so by law, to deduct or withhold (and shall not be required to make payments as otherwise required by this Section 4.04 on account of such deductions or withholdings) income or other
similar taxes imposed by the United States of America from interest, fees or other amounts payable hereunder for the account of any Lender other than a Lender (A) that is a U.S. Person for U.S. federal income tax purposes or (B) that has
the Prescribed Forms on file with the Borrower for the applicable year to the extent deduction or withholding of such taxes is not required as a result of such filing of such Prescribed Forms; provided that, if the Borrower shall so deduct or
withhold any such taxes, the Borrower shall provide a statement to the Administrative Agent and such Lender, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such
Lender may reasonably request for assisting such Lender to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender is subject to tax. 

 (ii)       Each Lender that is not a United States person (as such term is defined
in Section 7701(a)(30) of the Code) agrees to deliver to the Borrower and the Administrative Agent on or prior to the Effective Date, or in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to
Section 10.03 (unless 

  
 35 

 
the respective Lender was already a Lender hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Lender, (i) if the Lender is a
“bank” within the meaning of Section 881(c)(3)(A) of the Code, two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or Form W-8BEN-E or Form W-8ECI (or successor forms) or any other form (together with supplementary documentation) prescribed by applicable
laws (collectively, the “Prescribed Forms”) certifying such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Revolving Credit
Note, or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, either Internal Revenue Service Form W-8BEN or Form W-8BEN-E or Form W-8ECI as set forth in clause (i) above, or (x) a certificate in substantially the form of Schedule II (any such
certificate, a “Schedule II Certificate”) and (y) two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or
Form W-8BEN-E (or successor form) certifying such Lender’s entitlement to an exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and
under any Revolving Credit Note. In addition, each Lender agrees that it will deliver upon the Borrower’s request updated versions of the foregoing, as applicable, whenever the previous certification has become obsolete or inaccurate in any
material respect, together with such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or reduction in United States withholding tax with respect to payments under this
Agreement and any Revolving Credit Note. Notwithstanding anything to the contrary contained in this Section 4.04(a), but subject to the immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do
so by law, to deduct or withhold Taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender which is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. federal income tax purposes to the extent that such Lender has not provided to the Borrower U.S. Internal Revenue Service Forms that establish a complete
exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant to this Section 4.04(a) to gross-up payments to be made to a Lender in respect of Taxes imposed by the
United States if (I) such Lender has not provided to the Borrower the Internal Revenue Service Forms required to be provided to the Borrower pursuant to this Section 4.04(a) or (II) in the case of a payment, other than interest, to a
Lender described in clause (ii) above, to the extent that such Forms do not establish a complete exemption from withholding of such Taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this
Section 4.04, the Borrower agrees to pay additional amounts and to indemnify each Lender in the manner set forth in this Section 4.04(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect
of any amounts deducted or withheld by it as described in the immediately preceding sentence as a result of any changes after the Effective Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the
interpretation thereof, relating to the deducting or withholding of Taxes. 

  
 36 

 (b)       Additional Costs. Subject to
Sections 4.04(c), (d) and (e): 
  (i)         Without duplication of any
amounts payable described in Section 3.03(c) or 4.03(a), if after the date hereof, any Regulatory Change shall (1) impose, modify or deem applicable any reserve, special deposit or similar requirement against any Lender’s Commitment or
Loans, (2) subject the Administrative Agent or any Lender to any Taxes (other than (A) Indemnified Taxes, (B) Excluded Taxes (other than Taxes measured by the overall capital or net worth of the Administrative Agent or such Lender)
and (C) Other Connection 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 such
Lender’s Applicable Lending Office) any other condition regarding this Agreement, its Commitment or the Loans and the result of any event referred to in clause (1), (2) or (3) shall be to increase the cost to such Lender (or such
Lender’s Applicable Lending Office) of maintaining its Commitment or any Eurodollar Loans made by such Lender (which increase in cost shall be calculated in accordance with such Lender’s reasonable averaging and attribution methods) by an
amount which such Lender deems to be material, then, upon demand by such Lender, the Borrower shall pay to the Administrative Agent or such Lender, as the case may be, on demand, an amount equal to such increase in cost; and 

 (ii)        Without duplication of any amounts payable described in Section
3.03(c) or 4.03(a), if any Lender shall have determined that any Regulatory Change relating to capital adequacy or liquidity (including any Regulatory Change made prior to the date hereof but not effective until after the date hereof), or compliance
by such Lender (or such Lender’s Applicable Lending Office) with any Regulatory Change regarding capital adequacy or liquidity (whether or not having the force of law), has or would have the effect of, reducing the rate of return on capital for
such Lender (or such Lender’s Applicable Lending Office) or any corporation controlling such Lender as a consequence of its obligations under this Agreement to a level below that which such Lender (or such Lender’s Applicable Lending
Office) or such corporation could have achieved but for such Regulatory Change (taking into consideration such Lender’s (or such Lender’s Applicable Lending Office) or such corporation’s policies with respect to capital adequacy or
liquidity), then from time to time, upon demand by such Lender, the Borrower shall pay to such Lender, on demand, such additional amount or amounts as will compensate such Lender (or such Lender’s Applicable Lending Office) or such corporation
for such reduction. 
 (c)       Lending Office Designations. Before making any
demand for payment pursuant to this Section 4.04, each Lender shall, if possible, designate a different Applicable Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be
otherwise disadvantageous to such Lender. 
 (d)       Certificate, Etc. In
connection with any demand for payment pursuant to this Section 4.04, a Lender shall provide to the Borrower, with a copy to the Administrative 

  
 37 

 
Agent, a certificate, signed by an officer of such Lender, setting forth in reasonable detail the basis for such demand, the amount required to be paid by the Borrower to such Lender
and the computations made by such Lender to determine such amount. 

(e)       Limitations; Delay in Requests.   The Borrower shall not be
obligated to compensate a Lender for any amount under Section 4.04(b) arising or occurring more than (i) 90 days prior to the date on which an office of such Lender primarily responsible for the administration of this Agreement obtains actual
knowledge that such Lender is entitled to such compensation or (ii) nine months prior to the date that such Lender notifies the Borrower of the Regulatory Change giving rise to such increased costs or reductions, and of such Lender’s
intention to claim compensation therefor (except that, if the Regulatory Change 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). 
 (f)       FATCA. If a payment made to a Lender under any
Credit Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as
applicable), to the extent reasonably possible, such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower 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 the Borrower or the Administrative Agent as may be necessary for the Borrower
and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for
purposes of this Section 4.04(f), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

(g)       Cooperation. The Borrower agrees, upon the request of the Administrative
Agent or any Lender, promptly to execute, deliver and complete such forms, certificates and other documents, make such filings and otherwise cooperate with the Administrative Agent or such Lender, in each case as the Administrative Agent or such
Lender may reasonably request from time to time, in order for the Administrative Agent or such Lender to establish that the Administrative Agent or such Lender is not subject to, or is entitled to a reduction in the amount of or exemption from, any
deduction, withholding or other Taxes with respect to any payments to the Administrative Agent or such Lender for principal, interest, fees or other amounts under the Credit Documents, including United Kingdom HM Revenue & Customs’
Form DTTP2. 
 Section 15.05  Funding Impracticable. 

If at any time any Lender shall have determined in good faith (which determination shall be conclusive) that the making or
maintenance of all or any part of such Lender’s 

  
 38 

 
Eurodollar Loans has been made impracticable or unlawful because of compliance by such Lender in good faith with any law or guideline or interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration thereof or with any request or directive of such body (whether or not having the effect of law) or because U.S. dollar deposits in the amount and requested maturity of such
Eurodollar Loans are not available to such Lender in the London Eurodollar interbank market, then the Administrative Agent, upon notification to it of such determination by such Lender, shall forthwith advise the other Lenders and the Borrower
thereof. Upon such date as shall be specified in such notice and until such time as the Administrative Agent, upon notification to it by such Lender, shall notify the Borrower and the other Lenders that the circumstances specified by it in such
notice no longer apply, (i) notwithstanding any other provision of this Agreement, such Eurodollar Loans shall, automatically and without requirement of further notice, or any payment pursuant to Section 4.03 or 4.04, by the Borrower, be
converted to ABR Loans, and (ii) the obligation of such Lender to make or continue Eurodollar Loans shall be suspended, and, if the Borrower shall request in a Borrowing Request or Conversion Request that the Lenders make a Eurodollar Loan, the
Loan requested to be made by such Lender shall instead be made as an ABR Loan. 
 Section 15.06  Expenses;
Indemnity; Damage Waivers. 
 (a)       The Borrower agrees, whether or not any Loan
is made, to pay or reimburse the Administrative Agent all of its reasonable out-of-pocket fees and expenses incurred in connection with the development, preparation,
negotiation, execution, closing and syndication of, the Credit Documents and the administration of the credit facility established under the Credit Documents and any amendment, supplement or modification thereto (whether or not executed or
effective) and any documents prepared in connection therewith, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent and the maintenance of an electronic platform (including without limitation
charges of Debtdomain or any similar electronic information platform)) or information transmission systems in connection with this Agreement. 

(b)       The Borrower agrees to pay all reasonable out-of-pocket fees and expenses incurred by the Administrative Agent and, after the occurrence and during the continuance of an Event of Default, the Joint Lead Arrangers, the Joint Bookrunners or any Lender
(including, without limitation, the reasonable fees and disbursements of one counsel to the Administrative Agent, unless (and to the extent) conflicts of interest require the use of more than one counsel) in connection with the enforcement of, and
the protection of their respective rights under, any provision of any Credit Document or any amendment or supplement to this Agreement (including all such fees and expenses incurred during any “workout” or restructuring in respect of the
Obligations and during any legal proceeding, including any bankruptcy proceeding). 

(c)       The Borrower agrees to indemnify the Administrative Agent, the Joint Lead
Arrangers, the Joint Bookrunners, each of the Lenders and each of their respective 

  
 39 

 
Affiliates and their respective directors, officers, employees, agents and advisors (each, an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including counsel fees and expenses, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of any
Credit Document or any agreement or instrument contemplated by any Credit Document, the performance by the parties thereto of their respective obligations under any Credit Document or the consummation of the transactions contemplated by any Credit
Document, (ii) the use of the proceeds of the Loans or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto; provided that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or willful misconduct of such Indemnitee. In connection with any claim for indemnification pursuant to this Agreement by more than one Indemnitee, all such Indemnitees shall be represented by the same legal counsel selected by the
Indemnitees; provided that if such legal counsel determines in good faith that representing all such Indemnitees is reasonably likely to result in a conflict of interest under laws or ethical principles applicable to such legal counsel
or that a defense or counterclaim is available to an Indemnitee that is not available to all such Indemnitees, then to the extent reasonably necessary to avoid such a conflict of interest or to permit unqualified assertion of such a defense or
counterclaim, each Indemnitee shall be entitled to separate representation. 

(d)       All amounts due under this Section 4.06 shall be payable in immediately
available funds upon written demand therefor. 
 (e)       To the fullest extent
permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising
out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan, or the use of the proceeds thereof. No Indemnitee
referred to in paragraph (c) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission
systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby. 

Section 15.07  Survival. 

The provisions of Sections 4.03, 4.04, 4.06 and 9.06, shall remain operative and in full force and effect regardless of the
expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the reduction or termination of any Commitments, the invalidity or unenforceability of any

  
 40 

 
term or provision of any Credit Document, or any investigation made by or on behalf of the Lenders. 

Section 15.08  Replacement of a Lender. 

Notwithstanding anything to the contrary contained herein, if any Lender shall request compensation pursuant to Section
4.04(b)(i) or (ii) then, in each case, the Borrower may require that such Lender transfer all of its right, title and interest under this Agreement and such Lender’s Revolving Credit Notes to one or more of the other Lenders or any other
lender identified by the Borrower and reasonably acceptable to the Administrative Agent as a Replacement Lender which is willing to assume all of the obligations of such Lender, for consideration equal to the outstanding principal amount of such
Lender’s Loans, together with interest thereon to the date of such transfer and all other amounts payable under the Credit Documents to such Lender on or prior to the date of such transfer (including, without limitation, any fees accrued
hereunder and any amounts which would be payable under Section 4.03 as if all of such Lender’s Loans were being prepaid in full on such date). Subject to the execution and delivery of new notes, an Assignment and Acceptance, and such other
documents as such Lender may reasonably require, such Replacement Lender shall be a “Lender” for all purposes hereunder. Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements of the Borrower
contained in Sections 4.04 and 4.06 (without duplication of any payments made to such Lender by the Borrower or the Replacement Lender) shall survive for the benefit of any Lender replaced under this Section 4.08 with respect to the time prior
to such replacement.

tax-exempt status.

respect to any Plan to which the Borrower or any ERISA Affiliate (wherein the Borrower is or may be liable) contributes or is obligated to contribute. 

(iv)      None of the Pension Plans has any Unfunded Pension Liability in excess of ten percent
(10%) of the Net Worth as to which the Borrower is or may be liable.

 43

expects to incur (i) any liability (and no event has occurred which, with the giving of notice under Section 4219 of ERISA, would result in such liability) under Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan or

Effect. 
 (viii)    The Borrower has not transferred any Unfunded Pension Liability to any entity

otherwise due and payable except (a) those which are being contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with GAAP, and (b) those levied or imposed on Subsidiaries other
than Significant Subsidiaries the nonpayment of which would not, in the aggregate, have a Material Adverse Effect. To the best knowledge of the Borrower, there is no proposed tax assessment against the Borrower or any of its Subsidiaries which

respects with all applicable statutes and regulations, including ERISA and applicable occupational, safety and health and other labor laws, of all Governmental Authorities, a violation of which would have a Material Adverse Effect.

 THE
ADMINISTRATIVE AGENT 
 Section 20.01  The Agency. 

Each Lender appoints The Bank of New York Mellon as its agent hereunder and irrevocably authorizes the Administrative Agent to
take such action on its behalf and to exercise such powers hereunder as are specifically delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto, and the Administrative Agent hereby
accepts such appointment subject to the terms hereof. The relationship between the Administrative Agent and the Lenders shall be that of agent and principal only and nothing herein shall be construed to constitute the Administrative Agent a trustee
or fiduciary for any Lender nor to impose on the Administrative Agent duties or obligations other than those expressly provided for herein. 

Section 20.02  The Administrative Agent’s Duties. 

The Administrative Agent shall promptly forward to each Lender copies, or notify each Lender as to the contents, of all
notices received from the Borrower pursuant to the terms of this Agreement and, in the event that the Borrower fails to pay when due the 

  
 60 

 
principal of or interest on any Loan, the Administrative Agent shall promptly give notice thereof to the Lenders. As to any other matter not expressly provided for herein, the Administrative
Agent shall have no duty to act or refrain from acting with respect to the Borrower, except upon the instructions of the Required Lenders. The Administrative Agent shall not be bound by any waiver, amendment, supplement, or modification of this
Agreement which affects its duties hereunder, unless it shall have given its prior written consent thereto. The Administrative Agent shall have no duty to ascertain or inquire as to the performance or observance of any of the terms, conditions,
covenants or agreements binding on the Borrower pursuant to this Agreement nor shall the Administrative Agent be deemed to have knowledge of the occurrence of any Default or Event of Default (other than a failure of the Borrower to pay when due the
principal or interest on any Loan), unless it shall have received written notice from the Borrower or a Lender specifying such Default or Event of Default and stating that such notice is a “Notice of Default”. 

Section 20.03  Limitation of Liabilities. 

Each of the Lenders and the Borrower agree that (i) neither the Administrative Agent nor any of its officers or employees
shall be liable for any action taken or omitted to be taken by any of them hereunder except for its or their own gross negligence or willful misconduct as determined by a final and nonappealable ruling by a court of competent jurisdiction,
(ii) neither the Administrative Agent nor any of its officers or employees shall be liable for any action taken or omitted to be taken by any of them in good faith in reliance upon the advice of counsel, independent public accountants or other
experts selected by the Administrative Agent, and (iii) the Administrative Agent shall be entitled to rely upon any notice, consent, certificate, statement or other document believed by it to be genuine and correct and to have been signed
and/or sent by the proper Persons. 
 Section 20.04  The Administrative Agent as a Lender. 

The Administrative Agent may maintain deposits or credit balances for, invest in, lend money to and generally engage in any
kind of banking business with the Borrower or any Subsidiary or Affiliate of the Borrower without any duty to account therefor to the Lenders. 

Section 20.05  Lender Credit Decision. 

Neither the Administrative Agent, nor any of its Affiliates, officers or employees has any responsibility for, gives any
guaranty in respect of, nor makes any representation to the Lenders as to, (i) the condition, financial or otherwise, of the Borrower or any Subsidiary thereof or the truth of any representation or warranty given or made in this Agreement, or
in connection herewith or (ii) the validity, execution, sufficiency, effectiveness, construction, adequacy, enforceability or value of this Agreement or any other document or instrument related hereto. Except as specifically provided herein,
neither the Administrative Agent nor any of its Affiliates, officers or employees shall have any duty or responsibility, either initially or on a continuing basis, to provide any Lender 

  
 61 

 
with any credit or other information with respect to the operations, business, property, condition or creditworthiness of the Borrower or any of its Subsidiaries, whether such information comes
into the Administrative Agent’s possession on or before the date hereof or at any time thereafter. Each Lender acknowledges that (i) it has, independently and without reliance upon the Administrative Agent or any other Lender, based on
such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and (ii) all information reviewed by it in its credit analysis or otherwise in connection herewith has been
provided solely by or on behalf of the Borrower, and the Administrative Agent has no responsibility for such information. Each Lender also acknowledges that it will independently and without reliance upon the Administrative Agent or any other
Lender, based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under any Credit Document. 

Section 20.06  Indemnification. 

Each Lender agrees to indemnify the Administrative Agent, to the extent not reimbursed by the Borrower, ratably in proportion
to its Commitment, from and against any and all liabilities, obligations, losses, claims, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or
asserted against the Administrative Agent in any way relating to or arising out of this Agreement, or any action taken or omitted to be taken by the Administrative Agent hereunder; provided, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Administrative Agent or any of its officers or employees as determined
by a final and nonappealable ruling by a court of competent jurisdiction. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including fees and disbursements of counsel incurred by the Administrative Agent) in connection with the preparation, execution or enforcement of, or legal advice in respect of rights
or responsibilities under, any Credit Document or any amendments or supplements thereto, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower. Except for action expressly required of the Administrative
Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall receive further assurances to its satisfaction from the Lenders of their indemnification obligations under this
Section 9.06 against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. 

Section 20.07  Successor Administrative Agent 

The Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof (unless the parties agree
otherwise) to the Lenders and the Borrower. Upon 

  
 62 

 
any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent reasonably acceptable to the Borrower. If no successor Administrative Agent shall have
been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the resigning Administrative Agent’s giving of notice of resignation, the resigning Administrative Agent may appoint a successor
Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of its
appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigned Administrative
Agent, and the resigned Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any Administrative Agent’s resignation, the provisions of this Article IX shall continue to inure to its benefit as to
any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. 

Section 20.08  No Duty Regarding Discretionary Actions 

The Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as
shall be expressly provided for herein or in the other Credit Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to
liability or that is contrary to any Credit Document or applicable law.

Other Agents

The Borrower’s obligation to repay the Loans shall be evidenced by Revolving Credit Notes if requested by each Lender,
one such payable to the order of each such Lender. The Revolving Credit Note of each Lender shall (i) be in the principal amount of such Lender’s Commitment, (ii) be dated the Effective Date (or the effective date on which such Lender
becomes a Lender hereunder) and (iii) be stated to mature on the Termination 

  
 63 

 
Date and bear interest from its date until maturity on the principal balance (from time to time outstanding thereunder) payable at the rates and in the manner provided herein. Each Lender is
authorized to indicate upon the grid attached to its Revolving Credit Note all Loans made by it pursuant to this Agreement, interest elections and payments of principal and interest thereon. Such notations shall be presumptive, absent manifest
error, as to the aggregate unpaid principal amount of all Loans made by such Lender, and interest due thereon, but the failure by any Lender to make such notations or the inaccuracy or incompleteness of any such notations shall not affect the
obligations of the Borrower hereunder or under the Revolving Credit Notes. 

Section 21.02  Participations. 

(a)       Any Lender may at any time grant to one or more financial institutions (but not
to a natural Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person, or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each a
“Participant”) participating interests in its Commitment or any or all of its Loans. In the event of any such grant by a Lender of a participating interest to a Participant, whether or not upon notice to the Borrower and the
Administrative Agent, such Lender shall remain responsible for the performance of its obligations hereunder, and, except to the extent such participating interest has been granted pursuant to Section 4.02(e), the Borrower and the Administrative
Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide
that such Lender shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including the right to approve any amendment, modification or waiver of any provision of this Agreement; provided, that such
participation agreement may provide that such Lender will not agree to any modification, amendment or waiver of this Agreement described in clauses (i) through (vi), inclusive, of Section 11.06(b) without the consent of the Participant. 

(b)       Each Lender that sells a participation shall, acting solely for this purpose as a
non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the
Loans or other obligations under this Agreement (the “Participant Register”); provided that no Lender shall have any obligation to disclose any portion of the Participant Register to any Person (including the identity of any
Participant or any information relating to a Participant’s interest in any Commitments, Loans, or its other obligations under this Agreement) except to the extent that such disclosure is necessary to establish that such Commitment, Loan, 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, 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. 

  
 64 

 (c)       The Borrower agrees that each
Participant shall be entitled to the benefits of Sections 4.03 and 4.04(b) (subject to the requirements and limitations in Section 4.04, including the requirements under Section 4.04(a) (it being understood that the documentation required
under Section 4.04(a) 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 Section 10.03; provided that such Participant (A) agrees to be subject
to the provisions of Section 4.08 as if it were an assignee under Section 10.03; and (B) shall not be entitled to receive any greater payment under Section 4.04(b), 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 Regulatory Change that occurs after the Participant acquired the applicable participation. 

(d)       To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 11.04 as though it were a Lender; provided that such Participant agrees to be subject to Section 4.02(e) as though it were a Lender. 

Section 21.03 Assignments. 

(a)       Any Lender may at any time assign to one or more financial institutions (but not
to a natural Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person, or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each an
“Assignee”), other than a Defaulting Lender or a subsidiary thereof or any financial institution who, upon becoming a Lender hereunder, would constitute a Defaulting Lender or a subsidiary thereof, all, or a proportionate part of
all, of its rights and obligations under this Agreement, and such Assignee shall assume such rights and obligations, pursuant to an instrument, in substantially the form of Exhibit E (an “Assignment and Acceptance”), executed
by such Assignee and such transferring Lender, with (and subject to) the signed consent of the Borrower (which consent shall not be unreasonably withheld or delayed and which consent shall be deemed to have been given if the Borrower has not
responded within ten Business Days of its receipt of a written request for such consent) and the Administrative Agent (which consent shall not be unreasonably withheld); provided that (i) each such assignment (other than assignments
(x) to its Affiliates or (y) its entire interest) shall be in a minimum amount of $10,000,000 or in integral multiples of $1,000,000 in excess thereof (unless otherwise approved by the Administrative Agent in its sole discretion), (ii)
each assignee shall be an Eligible Institution, and (iii) after giving effect to each such assignment, the Commitment of the assignor (if it has not assigned its entire interest) and of the assignee shall be at least $5,000,000; provided
further, that the foregoing consent requirement shall not be applicable in the case of an assignment or other transfer by any Lender to an Affiliate of such Lender or to another Lender; provided further, that any consent of the Borrower
otherwise required under this Section shall not be required if an Event of Default has occurred and is continuing. Upon execution and delivery of an Assignment and Acceptance and payment by such Assignee to such transferring Lender of

  
 65 

 
an amount equal to the purchase price agreed between such transferring Lender and such Assignee and payment by the transferring Lender or the Assignee of an assignment fee of $4,500 (or $7,500,
if the transferring Lender is a Defaulting Lender) to the Administrative Agent (unless such fee is waived by the Administrative Agent in its sole discretion), such Assignee shall be a Lender party to this Agreement and shall have all the rights and
obligations of a Lender with a Commitment as set forth in such Assignment and Acceptance, and the transferring Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be
required. 
 (b)       No Assignee of any transferring Lender’s rights shall be
entitled to receive any greater payment under Section 4.03 or 4.04 than such Lender would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower’s prior written consent or by
reason of the provisions of Section 4.04(c) requiring such transferring Lender to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such payment did not exist. 

(c)       The Administrative Agent, acting solely for this purpose as an agent of the
Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts
of 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, and the Borrower, the Administrative Agent and the Lenders may 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, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice. 
 Section 21.04  Certain
Pledges. 
 Notwithstanding any other provision in this Agreement, any Lender may at any time create a security interest
in, or pledge, all or any portion of its rights under this Agreement and any Revolving Credit Note held by it in favor of any Federal Reserve Bank in accordance with Federal Reserve Board Regulation A (or any successor provision) or U.S. Treasury
Regulation 31 C.F.R. § 203.14 (or any successor provision), and such Federal Reserve Bank may enforce such pledge or security interest in any manner permitted under applicable law.

or (y) pursuant to legal process. In addition, the Administrative Agent and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending
industry and service providers to the Administrative Agent and the Lenders in connection with the administration of this Agreement, the other Credit Documents, and the Commitments.

modified, supplemented or waived, but only by a written amendment or supplement, or written waiver, signed by the Borrower and either the Required Lenders (and, if the rights or duties of the Administrative Agent are affected thereby, by the

omissions in the communications. The Administrative Agent makes no warranty of any kind, express, implied or statutory, including any warranty of merchantability, fitness for a particular purpose,
non-infringement of third party rights or freedom from viruses or other code defects in connection with the Communications or such electronic platform. In no event shall the Administrative Agent or any of its

or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of the Borrower’s or the Administrative Agent’s transmission of Communications electronically, except to the extent the liability of any such
person is found in a final and nonappealable ruling by a court of competent jurisdiction to have resulted primarily from such Person’s gross negligence or willful misconduct, and no claim may be made by the Borrower or any other Person against
the Administrative Agent or any or its directors, officers, employees, agents or advisors for any special, indirect, consequential or punitive damages in respect of any claim for breach of contract or any other theory of liability. 

(f)        The Administrative Agent and the Lenders shall be entitled to rely and act
upon any notices given by the Borrower even if such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein. All telephonic notices to and other communications
with the Administrative Agent may be recorded by the Administrative Agent, and each of the parties hereto hereby consents to such recording. 

Section 22.09  Separability. 

In case any one or more of the provisions contained in any Credit Document shall be invalid, illegal or unenforceable in any
respect under any law, the validity, legality and enforceability of the remaining provisions contained herein or in any other Credit Document shall not in any way be affected or impaired thereby. 

Section 22.10  Parties in Interest. 

This Agreement shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors
and assigns, except that the Borrower may not assign any of its rights hereunder without the prior written consent of all of the Lenders, and any purported assignment by the Borrower without such consent shall be void. 

Section 22.11  Execution in Counterparts. 

This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts,
each of which when so executed and delivered shall be an original, but all the counterparts, including counterparts delivered by telecopy or electronic format (including .pdf), shall together constitute one and the same instrument.

other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Credit Document; or 

(iii)      the variation of the terms of such liability in connection with the exercise of the
Write-Down and Conversion Powers of any EEA Resolution Authority.

 The

 REVOLVING CREDIT AGREEMENT, dated as of March 28, 2017, among
SOUTHWEST GAS HOLDINGS, INC., a California corporation (the “Borrower”), each of the lenders from time to time parties to this Agreement (collectively, the “Lenders”), and THE BANK OF NEW YORK MELLON, as
Administrative Agent (the “Administrative Agent”). 
 WITNESSETH: 

WHEREAS, the Borrower has requested the Lenders severally to commit to lend to the Borrower up to $100,000,000 on a revolving
basis to fund fees and expenses associated with this Agreement (as defined below) and for general corporate purposes; and 

WHEREAS, the Lenders are willing to make such loans, on the terms and conditions provided herein; 

NOW, THEREFORE, the parties agree as follows: 

ARTICLE I 

DEFINITIONS 

Section 1.01    Definitions. 

(a)    Terms Generally. The definitions ascribed to terms in this Agreement apply equally to both
the singular and plural forms of such terms. Whenever the context may require, any pronoun shall be deemed to include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and
“including” shall be interpreted as if followed by the phrase “without limitation”. The phrase “individually or in the aggregate” shall be deemed general in scope and not to refer to any specific Section or clause of
this Agreement. All references herein to Articles, Sections, Exhibits and Schedules shall be deemed references to Articles and Sections of, and Exhibits and Schedules to, this Agreement unless the context shall otherwise require. The table of
contents, headings and captions herein shall not be given effect in interpreting or construing the provisions of this Agreement. Except as otherwise expressly provided herein, all references to “dollars” or “$” shall be deemed
references to the lawful money of the United States of America. 
 (b)    Accounting Terms.
Except as otherwise expressly provided herein, the term “consolidated” and all other terms of an accounting nature shall be interpreted and construed in accordance with GAAP, as in effect from time to time; provided, however,
that, for purposes of determining compliance with any covenant set forth in Article VII, such terms shall be construed in accordance with GAAP as in effect on the date of this Agreement, applied on a basis consistent with the construction thereof
applied in preparing the Borrower’s audited financial statements referred to in Section 5.01(k). If 

 
there shall occur a change in GAAP which but for the foregoing proviso would affect the computation used to determine compliance with any covenant set forth in Article VII, the Borrower and the
Lenders agree to negotiate in good faith in an effort to agree upon an amendment to this Agreement that will permit compliance with such covenant to be determined by reference to GAAP as so changed while affording the Lenders the protection intended
to be afforded by such covenant prior to such change (it being understood, however, that such covenant shall remain in full force and effect in accordance with its existing terms unless and until such amendment shall become effective). 

(c)     Other Terms. The following terms have the meanings ascribed to them below or in the
Sections of this Agreement indicated below: 
 “ABR Loans” means Loans that bear interest at a rate or
rates determined by reference to the Alternate Base Rate. 
 “Acquisition” means any purchase or other
acquisition by the Borrower or a direct or indirect Subsidiary of the Borrower of (a) any assets of any other Person that, taken together, constitute a business unit, or (b) any capital stock of or equity interests in any other Person if,

“Act” has the meaning assigned to such term in Section 11.12.

the Lenders, or any successor administrative agent appointed pursuant to the terms of this Agreement.

“Affiliate” means, when used with reference to any Person, a Person (other than a Subsidiary) which directly
or indirectly controls, is controlled by, or is under common control with, such other Person. For purposes of this definition, “control” (including with correlative meanings, the terms “controlling,” “controlled by” and
“under common control with”) as applied to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of that Person, whether through the ownership of voting
securities or by contract or otherwise. 
 “Agreement” means this Revolving Credit Agreement, as it may be
amended, modified or supplemented from time to time.

publicly announced by the Administrative Agent as its prime commercial loan rate in effect on such day; 

(ii)    the sum of (a) 1/2 of 1% per annum and (b) the Federal Funds
Effective Rate in effect on such day; and 
 (iii)    the sum of (a) 1% per
annum and (b) the One Month LIBOR Rate in effect on such date.

foregoing rates shall change. Any change in the Alternate Base Rate shall become effective as of the opening of business on the day of such change.

THE CREDIT FACILITY 

Section 2.01    Loans. 

Until the Termination Date, subject to the terms and conditions of this Agreement, each of the Lenders, severally and not
jointly with the other Lenders, agrees to make loans (collectively, the “Loans”) in dollars to the Borrower in an aggregate principal amount at any one time outstanding not to exceed such Lender’s Commitment. Loans shall be
made on any Borrowing Date only (i) in the minimum aggregate principal amount of $2,500,000 or in integral multiples of $1,000,000 in excess thereof, in the case of Eurodollar Loans, and in the minimum aggregate amount of $1,000,000 or in
integral multiples of $100,000, in the case of ABR Loans and (ii) in a maximum aggregate principal amount not exceeding the Available Commitment (after giving effect to any repayments or prepayments and any other borrowings of Loans on such
Borrowing Date). 
 Section 2.02    Borrowing Procedure. 

In order to borrow Loans, the Borrower shall give a Borrowing Request to the Administrative Agent not later than 12:00 noon,
New York time, (i) on the Borrowing Date for ABR Loans and (ii) on the third Business Day before the Borrowing Date for Eurodollar Loans. Upon receipt, the Administrative Agent forthwith shall give notice to each Lender of the substance of
the Borrowing Request. Not later than 2:00 P.M., New 

  
 22 

 
York time, on the Borrowing Date, each Lender shall make available to the Administrative Agent such Lender’s Pro Rata Share of the requested Loans in funds immediately available at the
Administrative Agent’s office specified pursuant to Section 11.08(a). Subject to satisfaction, or waiver by the Lenders required to waive any condition precedent not satisfied, of each of the applicable conditions precedent contained in
Article VI, on the Borrowing Date the Administrative Agent shall make available, in like funds, to the Borrower the amounts received by the Administrative Agent from the Lenders. 

Section 2.03    Termination, Reduction, Increase and Extension of Commitments. 

(a)    Unless previously terminated, the Commitments shall terminate on the Termination Date. 

(b)    The Borrower may terminate the Total Commitment, or reduce the amount thereof, by (i) giving
written notice to the Administrative Agent, not later than 5:00 P.M., New York time, on the fifth Business Day prior to the date of termination or reduction and (ii) paying the amount of the Commitment Fees accrued through such date of
termination or reduction. Reductions of the Total Commitment shall be in the amount of $2,500,000 or in integral multiples of $1,000,000 in excess thereof (or, if the amount of the Available Commitment is less than $2,500,000, then all of such
lesser amount), but shall not exceed the Available Commitment in effect immediately before giving effect to such reduction. Any termination, and all reductions, of the Total Commitment shall be permanent. 

(c)    The Borrower may from time to time, at its sole expense and effort after consulting with the
Administrative Agent, request: (i) one or more Lenders to increase (in the sole and absolute discretion of each such Lender) the amount of their respective Commitments and/or (ii) one or more other lending institutions reasonably
acceptable to the Administrative Agent (each, a “New Lender”) to become “Lenders” and extend Commitments hereunder (each such Lender and each New Lender being herein referred to as a “Proposed Lender”). To
request an increase pursuant to this Section 2.03(c), the Borrower shall submit to the Administrative Agent an Increase Request, in the form annexed hereto as Exhibit G, signed by the Borrower, which shall be irrevocable and shall
specify, as the case may be: (A) each such Lender and the amount of the proposed increase in its Commitment, or (B) the proposed Commitment for such New Lender. Promptly following receipt of an Increase Request, the Administrative Agent
shall advise each Lender of the details thereof. If one or more of such Proposed Lenders shall have unconditionally agreed to such Increase Request in a writing delivered to the Borrower and the Administrative Agent (each such existing Lender and
New Lender being hereinafter referred to as an “Incremental Lender”), then: (1) each such Incremental Lender which shall then be an existing Lender shall have its Commitment increased by the amount set forth in such Increase
Request, and (2) each such New Lender shall be and become a “Lender” hereunder having a Commitment equal to the amount set forth 

  
 23 

 
therefor in such Increase Request, provided, however, that in each such case: (I) immediately before and after giving effect thereto, no Default or Event of Default shall or would
exist, (II) each such Incremental Lender shall have executed and delivered to the Administrative Agent a supplement to this Agreement, in the form annexed hereto as Exhibit I, providing for its increased Commitment or its Commitment, as
applicable, in form approved by the Administrative Agent, (III) immediately after giving effect thereto, the Total Commitment under this Agreement shall not exceed $200,000,000, (IV) each such Increase Request shall be in an aggregate minimum amount
of $10,000,000 or an integral multiple of $5,000,000 in excess thereof, and (V) the Commitment extended by any such Incremental Lender which is a New Lender shall be in a minimum amount of $5,000,000 or an integral multiple of $1,000,000 in
excess thereof. 
 (d)    Simultaneously with each increase in the aggregate amount of the Commitments
under Section 2.03(c), each Incremental Lender shall, to the extent necessary, purchase from each other Lender, and each other Lender shall sell to each Incremental Lender, in each case at par and without representation, warranty, or recourse
(in accordance with and subject to the restrictions contained in Section 10.03), such principal amount of the Loans of such other Lender, together with all accrued and unpaid interest thereon, as will result, after giving effect to such
transaction, in each Lender’s Applicable Percentage of Loans outstanding being equal to such Lender’s Applicable Percentage of all Loans, provided that each such assignor Lender shall have received (to the extent of the interests,
rights and obligations assigned) payment of the outstanding principal amount of such Loans, accrued interest thereon, accrued fees, commissions and all other amounts payable to it under the Credit Documents from the applicable assignee Lenders (to
the extent of such outstanding principal and accrued interest, fees and commissions) or the Borrower (in the case of all other amounts). 

(e)    The Borrower may, by written notice to the Administrative Agent (which shall promptly deliver a
copy to each of the Lenders) not less than 30 days and not more than 90 days prior to the first, second, third, fourth and/or fifth anniversary of the Effective Date, an Extension Request, in the form annexed hereto as Exhibit H, signed by
the Borrower, request that the Lenders extend the Termination Date then in effect and the Commitments for an additional period of one year. Each Lender shall, by notice to the Borrower and the Administrative Agent given not later than the 15th day
after the date of the Administrative Agent’s receipt of the Borrower’s extension request, advise the Borrower whether or not it agrees to the requested extension (each Lender agreeing to a requested extension being called a
“Consenting Lender” and each Lender declining to agree to a requested extension being called a “Declining Lender”). Any Lender that has not so advised the Borrower and the Administrative Agent by such day shall be
deemed to have declined to agree to such extension and shall be a Declining Lender. If Lenders constituting the Required Lenders shall have agreed to an extension request in their sole and absolute discretion, then the Termination Date shall, as to
the Consenting Lenders, be extended to the first anniversary of the Termination Date theretofore in effect. The decision to agree or withhold agreement to any Termination Date extension shall be at the

  
 24 

 
sole discretion of each Lender. The Commitment of any Declining Lender shall terminate on the Termination Date in effect prior to giving effect to any such extension (such Termination Date being
called the “Existing Termination Date”). Notwithstanding the foregoing provisions of this Section 2.03(e), the Borrower shall have the right, with the prior written consent (not to be unreasonably withheld) of the
Administrative Agent, at any time prior to the Existing Termination Date, to replace a Declining Lender with a Lender or Eligible Institution that will agree to a request for the extension of the Termination Date then in effect, and any such
Replacement Lender shall for all purposes constitute a Consenting Lender, provided, however, that in each such case (i) each such Replacement Lender shall have executed and delivered to the Administrative Agent a supplement to this Agreement,
in the form annexed hereto as Exhibit J, providing for its Commitment, and (ii) the Declining Lender shall assign, in accordance with Section 10.03(a), all or part, as the case may be, of its Loans, Commitment, Revolving Credit Note
and other rights and obligations under this Agreement and all other Credit Documents to such Replacement Lender, in exchange for payment of the principal of, and interest accrued to the date of such payment on, Loans owing to such Declining Lender
and any accrued Commitment Fees owing to such Declining Lender; and upon such payments, the obligations of such Declining Lender hereunder in respect of its Commitment shall, by the provisions hereof, be released and discharged and such Replacement
Lender shall be and become a “Lender” hereunder having a Commitment equal to the amount set forth therefor in such supplement. Notwithstanding the foregoing, no extension of the Termination Date pursuant to this paragraph shall become
effective unless (i) the Administrative Agent shall have received documents consistent with those delivered with respect to the Lender under Section 6.01(c), (d), (e)(ii) (it being understood and agreed that the date referred to in
Section 6.01(e)(ii) shall refer to the date of the then most recently delivered audited financial statements required to be delivered pursuant to Section 7.01(a)(i)), (e)(iii), (e)(iv) and (e)(v), giving effect to such extension and
(ii) on the date on which the Required Lenders shall have agreed to an extension request, (A) the conditions set forth in Section 6.02(b) shall be satisfied and (B) the representations and warranties contained in
Section 5.01 shall be true and correct in all material respects (except to the extent that any representation or warranty speaks as of a date certain), except for any representation or warranty that is qualified by materiality or reference to
Material Adverse Effect (in which case such representation or warranty shall be true and correct in all respects), and the Administrative Agent shall have received a certificate with respect to the matters referred to in clauses (A) and
(B) dated such date and executed by a Responsible Officer. Unless a Declining Lender ceases to be a Lender hereunder pursuant to the above provisions in this Section 2.03(e), the Borrower hereby agrees to pay to the Administrative Agent in
accordance with the terms of this Agreement, for distribution to the Declining Lenders, all of the outstanding Loans made by the Declining Lenders, together with all accrued and unpaid interest thereon and all accrued fees and other amounts payable
to or for the accounts of the Declining Lenders on the Existing Termination Date, and, upon each Declining Lender’s receipt of such amounts, such Declining Lender shall cease to be a Lender hereunder. 

  
 25 

 Section 2.04    Repayment. 

All Loans shall be repaid, together with all accrued and unpaid interest thereon, on the Termination Date. 

Section 2.05    Optional Prepayment. 

The Borrower may prepay Loans bearing interest on the same basis and having the same Interest Periods, if any, by giving
notice to the Administrative Agent not later than 1:00 P.M., New York time, on the third Business Day preceding the proposed date of prepayment, in the case of Eurodollar Loans, or not later than 1:00 P.M., New York time, on the Business Day of the
proposed prepayment, in the case of ABR Loans. Each such prepayment of Eurodollar Loans shall be in an aggregate principal amount of $2,500,000 or in integral multiples of $1,000,000 in excess thereof (or, if the aggregate amount of outstanding
Eurodollar Loans is less than $2,500,000, then all of such lesser amount), and each prepayment of ABR Loans shall be in an aggregate amount of $1,000,000 or in integral multiples of $100,000 in excess thereof (or, if the aggregate amount of
outstanding ABR Loans is less than $1,000,000, then all of such lesser amount), and, in the case of Eurodollar Loans, together with the amounts required by Section 4.03, accrued interest on the principal being prepaid to the date of prepayment.
Subject to the terms and conditions of this Agreement, prepaid Loans may be reborrowed. 

Section 2.06    Defaulting Lenders. 

(a)    Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting
Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: 

(i)    Commitment Fees shall cease to accrue on the Commitment of such Defaulting Lender pursuant to
Section 3.07; 
 (ii)    the Commitment and Loans of such Defaulting Lender shall not be included
in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 11.06); provided that any waiver, amendment or modification that would
(A) increase the Commitment of such Defaulting Lender or subject such Defaulting Lender to any additional obligations, (B) reduce the principal of, or interest on, the Loans made by such Defaulting Lender or (C) postpone any date
fixed for any payment of principal of, or interest on, the Loans made by such Defaulting Lender (which, for avoidance of doubt, shall not include forbearing from exercising remedies as a result thereof), shall require the consent of such Defaulting
Lender; and 
 (iii)    any amount payable to such Defaulting Lender hereunder (whether on account of
principal, interest, fees or otherwise and including any amount that would 

  
 26 

 
otherwise be payable to such Defaulting Lender) shall, in lieu of being distributed to such Defaulting Lender, be retained by the Administrative Agent in a segregated account and, subject to any
applicable requirements of law, be applied at such time or times as may be determined by the Administrative Agent, in the following order of priority: (A) first, to the payment of any amounts owing by such Defaulting Lender to the
Administrative Agent hereunder, (B) second, as the Borrower may request (so long as no Default or Event of Default exists) to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required
by this Agreement, (C) third, if so determined by the Administrative Agent and the Borrower, held in such account as cash collateral for future funding obligations of the Defaulting Lender in respect of any Loans under this Agreement, and
(D) fourth, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a
result of such Defaulting Lender’s breach of its obligations under this Agreement. 
 (b)    The
Borrower may, by ten Business Days’ notice in writing to the Administrative Agent and a Defaulting Lender, (i) request such Defaulting Lender to cooperate with the Borrower in obtaining a Replacement Lender for such Defaulting Lender;
(ii) request the non-Defaulting Lenders to acquire and assume all or a portion of such Defaulting Lender’s Loans and Commitment, but none of such Lenders shall be obligated to do so; or (iii) propose a Replacement Lender. If a
Replacement Lender shall be accepted by the Administrative Agent or one or more of the non-Defaulting Lenders shall agree to acquire and assume all or part of a Defaulting Lender’s Loans and Commitment, then such Defaulting Lender shall assign,
in accordance with Section 10.03(a), all or part, as the case may be, of its Loans, Commitment, Revolving Credit Note and other rights and obligations under this Agreement and all other Credit Documents to such Replacement Lender or
non-Defaulting Lenders, as the case may be, in exchange for payment of the principal of, and interest accrued to the date of such payment on, Loans owing to such Defaulting Lender and any accrued Commitment Fees owing to such Defaulting Lender; and
upon such payments, the obligations of such Defaulting Lender hereunder in respect of its Commitment shall, by the provisions hereof, be released and discharged; provided, however, that such Defaulting Lender’s rights under
Sections 4.03, 4.04 and 4.06, and its obligations under Section 9.06 shall survive such release and discharge as to matters occurring prior to such date; provided further, however, that such assignment shall be on the terms and
conditions set forth in Section 10.03(a). If the Replacement Lender and the non-Defaulting Lenders shall only be willing to acquire less than all of a Defaulting Lender’s outstanding Loans and Commitment, the Commitment of such Defaulting
Lender shall not terminate, but shall be reduced proportionately, and such Defaulting Lender shall continue to be a “Lender” hereunder with a reduced Commitment and Pro Rata Share. Upon the effective date of such assignment, such
Replacement Lender shall, if not already a Lender, become a “Lender” for all purposes under this Agreement and the other Credit Documents. 

  
 27 

 (c)    The rights and remedies against a Defaulting Lender
under this Section 2.06 are in addition to other rights and remedies that the Borrower, the Administrative Agent or any Lender may have against such Defaulting Lender. 

(d)    In the event that the Administrative Agent and the Borrower agree that a Defaulting Lender has
adequately remedied all matters that caused such Lender to be a Defaulting Lender, then such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to
hold such Loans ratably in accordance with its Commitments and such Lender shall no longer 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 Borrower while that Lender 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 Lender’s having been a Defaulting Lender. 
 ARTICLE III 

INTEREST AND FEES 

Section 3.01    Interest Rate Determination; Conversion. 

(a)    Except to the extent that the Borrower shall request, in a Borrowing Request, in a Conversion
Request or in a written election pursuant to Section 3.03(b), that Loans (or portions thereof) bear interest as Eurodollar Loans, Loans shall bear interest as ABR Loans. 

(b)    The Borrower may request, by giving a Conversion Request to the Administrative Agent, not later
than 1:00 P.M., New York time, on the third Business Day prior to the requested Conversion Date, that all or portions of the outstanding Loans, in the aggregate principal amount of $2,500,000 or in integral multiples of $1,000,000 in excess thereof,
in the case of Loans being converted to or continued as Eurodollar Loans, and in the aggregate principal amount of $1,000,000 or in integral multiples of $100,000 in excess thereof (or, if the aggregate principal amount of outstanding Loans is less
than $1,000,000, then all such lesser amount), in the case of ABR Loans, bear interest from and after the Conversion Date as either ABR Loans or Eurodollar Loans; provided, however, that during the continuance of any Default or Event
of Default that shall have occurred, no Loan (or portion thereof) may be converted into Eurodollar Loans. Upon receipt, the Administrative Agent forthwith shall give notice to each Lender of the substance of each Conversion Request. Upon payment by
the Borrower of the amounts, if any, required by Section 4.03, on the Conversion Date the Loans or portions thereof as to which the Conversion Request was made shall commence to accrue interest in the manner selected by the Borrower therein.

  
 28 

 Section 3.02    Interest on ABR Loans. 

Each ABR Loan shall bear interest from the date made until the date repaid, or (if converted into a Eurodollar Loan) to (but
excluding) the first day of any relevant Interest Period, as the case may be, payable in arrears on the last day of each calendar quarter of each year, commencing with the first such date after the Effective Date, and on the date such Loan is
repaid, at a rate per annum equal to the sum of (i) the Applicable Margin and (ii) the Alternate Base Rate in effect from time to time, which rate shall change as and when said Applicable Margin or Alternate Base Rate shall change. 

Section 3.03    Interest on Eurodollar Loans. 

(a)    Each Eurodollar Loan shall bear interest from the date made until the date repaid or converted to
an ABR Loan, payable in arrears, with respect to Interest Periods of three months or less, on the last day of such Interest Period, and with respect to Interest Periods longer than three months, the respective dates that fall every three months
after the commencement of such Interest Period and on the last day of such Interest Period, at a rate per annum equal to the sum of (i) the Applicable Margin and (ii) the LIBOR rate for such Interest Period. 

(b)    Each Eurodollar Loan shall become an ABR Loan at the end of the Interest Period therefor, unless
(i) there shall not have occurred and be continuing a Default or Event of Default and (ii) not later than the third Business Day prior to the last day of such Interest Period, (x) the Borrower shall have delivered to the
Administrative Agent an irrevocable written election of the subsequent Interest Period, in which case such Eurodollar Loan shall remain outstanding as a Eurodollar Loan, or (y) the Borrower shall have delivered to the Administrative Agent a
Conversion Request with respect thereto, in which case such Eurodollar Loan shall be converted in accordance with Section 3.01(b). 

(c)    If, during any period, a Lender shall be required to maintain reserves against “Eurocurrency
Liabilities” in accordance with Federal Reserve Board Regulation D (or any successor regulation), the Borrower shall pay additional interest during such period on each outstanding Eurodollar Loan of such Lender (contemporaneously with each
interest payment due thereon commencing with the first such payment due at least five Business Days after receipt of the notice referred to in the next sentence) at a rate per annum up to but not exceeding the marginal rate determined by the
following formula: 
  

					
		 	 LIBOR
	 	-  LIBOR
		 	  l -Eurodollar Reserve Percentage	 	

 Each Lender shall promptly notify the Borrower, with a copy to the Administrative Agent, upon becoming aware
that the Borrower may be required to make a payment of additional interest to such Lender. When requesting payment pursuant to this Section 3.03(c), a Lender shall provide to the Borrower, with a copy to the Administrative Agent,

  
 29 

 
a certificate, signed by an officer of such Lender setting forth, in reasonable detail, the basis of such claim, the amount required to be paid by the Borrower to such Lender and the computations
made by such Lender to determine such amount. Absent demonstrable error, such certificate shall be binding as to the amounts of additional interest owing in respect of such Lender’s Eurodollar Loans. Any Lender that gives notice under this
Section 3.03(c) shall promptly withdraw such notice (by written notice of withdrawal given to the Administrative Agent and the Borrower) whenever such Lender is no longer required to maintain such reserves or the circumstances giving rise to
such notice shall otherwise cease. 
 Section 3.04    Interest on Overdue Amounts. 

All overdue amounts (including principal, interest and fees) hereunder shall bear interest, payable on demand, at a rate per
annum equal to the sum of (i) 2% and (ii) in the case of Eurodollar Loans, the rate then applicable until the end of the current Interest Period therefor, and thereafter the rate of interest applicable to ABR Loans, changing as and when
such rate shall change, and in the case of ABR Loans, the rate of interest applicable thereto, changing as and when such rate shall change. 

Section 3.05    Day Counts. 

Interest on ABR Loans shall be calculated on the basis of (a) a 365- or, if
applicable, a 366-day year for the actual number of days elapsed for so long as interest is determined pursuant to clause (i) of the definition of “Alternate Base Rate” and (b) a 360-day year for the actual number of days elapsed for so long as interest is determined based on clause (ii) or clause (iii) of the definition of “Alternate Base Rate”. Interest on all other
Loans, and all fees shall be calculated on the basis of a 360-day year for the actual number of days elapsed. 

Section 3.06    Maximum Interest Rate. 

(a)    Nothing in this Agreement shall require the Borrower to pay interest at a rate exceeding the
maximum rate permitted by applicable law. Neither this Section nor Section 11.01 is intended to limit the rate of interest payable for the account of any Lender to the maximum rate permitted by the laws of the State of New York (or any other
applicable law) if a higher rate is permitted with respect to such Lender by supervening provisions of U.S. Federal law. 

(b)    If the amount of interest payable for the account of any Lender on any interest payment date in
respect of the immediately preceding interest computation period, computed pursuant to this Article III, would exceed the maximum amount permitted by applicable law to be charged by such Lender, the amount of interest payable for its account on such
interest payment date shall automatically be reduced to such maximum permissible amount. 

  
 30 

 (c)    If the amount of interest payable for the account of
any Lender in respect of any interest computation period is reduced pursuant to Section 3.06(b) and the amount of interest payable for its account in respect of any subsequent interest computation period would be less than the maximum amount
permitted by law to be charged by such Lender, then the amount of interest payable for its account in respect of such subsequent interest computation period shall be automatically increased to such maximum permissible amount; provided that at
no time shall the aggregate amount by which interest paid for the account of any Lender has been increased pursuant to this Section 3.06(c) exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant
to Section 3.06(b). 
 Section 3.07    Commitment Fees. 

The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, on the last day of each calendar
quarter of each year, commencing with the first such day after the Effective Date (or such later date on which such Lender becomes a Lender), and on the Termination Date (or other date on which the Commitment shall terminate) with respect to such
Lender, a fee (the “Commitment Fee”) computed by applying (i) on each day on which the applicable Pricing Level set forth below is in effect, the percentage per annum set forth below adjacent to such Pricing Level on such day
during the then-ending quarter (or shorter period ending with the Termination Date or any other date on which the Commitment of such Lender shall terminate) to (ii) the amount of such Lender’s Unused
Commitment on such day:

DISBURSEMENT AND PAYMENT 

Section 4.01    Disbursement. 

(a)    Each Loan shall be made by the relevant Lender from such Lender’s branch or affiliate
identified as its Applicable Lending Office. 
 (b)    The failure of any Lender to make any Loan to be
made by it on the Borrowing Date therefor shall not relieve any other Lender of its obligation to make its Loan or Loans on such date, but neither any Lender nor the Administrative Agent shall be responsible for the failure of any other Lender to
make a Loan to be made by such other Lender. 
 (c)    The Administrative Agent may, but shall not be
required to, advance on behalf of any Lender the amount of such Lender’s Loan to be made on a Borrowing Date, unless such Lender shall have notified the Administrative Agent prior to such Borrowing Date that it does not intend to make such Loan
on such date. If the Administrative Agent makes any such advance, the Administrative Agent shall be entitled to recover the amount so advanced on demand from the Lender on whose behalf such advance was made and, if such Lender does not pay the
Administrative Agent the amount of such advance on demand, the Borrower agrees promptly to repay such amount to the Administrative Agent. Until such amount is repaid to the Administrative Agent by such Lender or the Borrower, such advance shall be
deemed for all purposes to be a Loan made on such Borrowing Date by the Administrative Agent. The Administrative Agent shall be entitled to recover from the Lender or the Borrower, as the case may be, interest on the amount advanced by it for each
day from the Borrowing Date therefor until repaid to the Administrative Agent, at a rate per annum equal to the Federal Funds Effective Rate until the third Business Day after the date of the advance and, thereafter, at the rate per annum equal to
the relevant rate on Loans made on the relevant Borrowing Date. 
 Section 4.02    Method and
Time of Payments; Sharing among Lenders. 
 (a)    All funds received by the Administrative Agent
for the account of the Lenders in respect of payments made by the Borrower under, or from any other Person on account of, any Credit Document shall be distributed forthwith by the Administrative Agent among the Lenders, in like funds as received,
ratably in proportion to their respective interests therein. Each payment of Commitment Fees and each reduction of the Total Commitment shall be apportioned among the Lenders in proportion to each Lender’s Pro Rata Share. 

(b)    All payments by the Borrower hereunder shall be made without setoff or counterclaim to the
Administrative Agent, for its account or for the account of the Lender or Lenders entitled thereto, as the case may be, in dollars and in immediately available 

  
 32 

 
funds at the office of the Administrative Agent prior to 3:00 P.M., New York time, on the date when due; provided, however, that the Borrower shall have setoff rights with respect to any
Defaulting Lender with the application of any amounts payable to a Defaulting Lender to be administered by the Administrative Agent pursuant to Section 2.06(a)(iii). 

(c)    Whenever any payment from the Borrower shall be due on a day that is not a Business Day, the date
of payment thereof shall be extended to the next succeeding Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. 

(d)    Unless the Administrative Agent shall have received notice from the Borrower prior to the date on
which any payment from the Borrower is due that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative
Agent may, in reliance upon such assumption, but shall not be obligated to, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made
such payment, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Administrative Agent, at the Federal Funds Effective Rate. 
 (e)    If
any Lender shall receive from the Borrower or any other Person any amount owing under any Credit Document (whether received pursuant to the exercise of any right of set-off, banker’s lien, realization
upon any security held for or appropriated to such obligation or otherwise) other than in proportion to such Lender’s ratable share thereof, then such Lender shall purchase from each other Lender a participating interest in so much of the other
Lenders’ Loans as shall be necessary in order that each Lender shall share such payment with each of the other Lenders in proportion to each Lender’s ratable share; provided that nothing herein contained shall obligate any Lender to
apply any set-off, banker’s lien or collateral security first to the obligations of the Borrower hereunder if the Borrower is obligated to such Lender pursuant to other loans or notes. If any purchasing
Lender shall be required to return any excess payment received by it, such participation shall be rescinded and the purchase price restored to the extent of such return, but without interest. 

Section 4.03    Compensation for Losses. 

(a)    If (i) the Borrower makes a prepayment, or a Conversion Date occurs, other than on the last
day of the relevant Interest Period, (ii) the Borrower fails to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, (iii) the Borrower revokes any Borrowing Request for
Eurodollar Loans, (iv) Eurodollar Loans (or portions thereof) are converted into ABR Loans pursuant to Section 4.05 at any time other than at the end of an Interest Period or (v) Loans (or portions thereof) shall become or be declared
to be due prior to the 

  
 33 

 
scheduled maturity thereof, then the Borrower shall pay to each Lender an amount that will compensate such Lender for any loss (other than lost profit) or premium or penalty incurred by such
Lender as a result of such prepayment, conversion, declaration or revocation in respect of funds obtained for the purpose of making or maintaining such Lender’s Eurodollar Loans, or any portion thereof. Such compensation shall include an amount
equal to the excess, if any, of (i) the amount of interest which would have accrued on the amount so paid or prepaid, or not borrowed or converted, for the period from the date of such payment or prepayment or conversion or failure to borrow to
the last day of such Interest Period (or, in the case of a failure to borrow, the Interest Period that would have commenced on the date of such failure to borrow) in each case at the applicable rate of interest for such Eurodollar Loan provided for
herein (excluding, however, any Applicable Margin included therein) over (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a
comparable period with leading banks in the London interbank deposit market. 
 (b)    In connection
with a demand for payment pursuant to this Section 4.03, a Lender shall provide to the Borrower, with a copy to the Administrative Agent, a certificate, signed by an officer of such Lender, setting forth in reasonable detail the amount required
to be paid by the Borrower to such Lender and the computations made by such Lender to determine such amount. In the absence of demonstrable error, such certificate shall be conclusive as to the amount so required to be paid. 

Section 4.04    Withholding and Additional Costs. 

(a)    Withholding. (i) To the extent permitted by law, all payments under this Agreement and
under the Revolving Credit Notes (including payments of principal and interest) shall be payable to each Lender free and clear of any and all present and future taxes, levies, imposts, duties, deductions, withholdings, fees, liabilities and similar
charges other than Excluded Taxes (collectively, “Taxes”). If any Taxes are required to be withheld or deducted from any amount payable under this Agreement, then the amount payable under this Agreement shall be increased to the
amount which, after deduction from such increased amount of all Taxes required to be withheld or deducted therefrom, will yield to such Lender the amount stated to be payable under this Agreement. The Borrower shall also hold each Lender harmless
and indemnify it for any stamp or other taxes with respect to the preparation, execution, delivery, recording, performance or enforcement of the Credit Documents (all of which shall be included within “Taxes”). If any of the Taxes
specified in this Section 4.04(a) are paid by any Lender, the Borrower shall, upon demand of such Lender, promptly reimburse such Lender for such payments, together with any interest, penalties and expenses incurred in connection therewith;
provided, however, that the Borrower shall not be required to reimburse any Lender for any penalties incurred or caused by the failure or delay on the part of such Lender to pay any of the Taxes specified in this Section 4.04(a).
The Borrower shall deliver to the Administrative Agent certificates or other valid vouchers for all Taxes or other charges 

  
 34 

 
deducted from or paid with respect to payments made by the Borrower hereunder. Notwithstanding the foregoing, the Borrower shall be entitled, to the extent required to do so by law, to deduct or
withhold (and shall not be required to make payments as otherwise required by this Section 4.04 on account of such deductions or withholdings) income or other similar taxes imposed by the United States of America from interest, fees or other
amounts payable hereunder for the account of any Lender other than a Lender (A) that is a U.S. Person for U.S. federal income tax purposes or (B) that has the Prescribed Forms on file with the Borrower for the applicable year to the extent
deduction or withholding of such taxes is not required as a result of such filing of such Prescribed Forms; provided that, if the Borrower shall so deduct or withhold any such taxes, the Borrower shall provide a statement to the Administrative Agent
and such Lender, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender may reasonably request for assisting such Lender to obtain any allowable credits or
deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender is subject to tax. 

(ii)    Each Lender that is not a United States person (as such term is defined in
Section 7701(a)(30) of the Code) agrees to deliver to the Borrower and the Administrative Agent on or prior to the Effective Date, or in the case of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to
Section 10.03 (unless the respective Lender was already a Lender hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Lender, (i) if the Lender is a “bank” within the
meaning of Section 881(c)(3)(A) of the Code, two accurate and complete original signed copies of Internal Revenue Service Form W-8BEN or Form W-8BEN-E or Form W-8ECI (or successor forms) or any other form (together with supplementary
documentation) prescribed by applicable laws (collectively, the “Prescribed Forms”) certifying such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this
Agreement and under any Revolving Credit Note, or (ii) if the Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, either Internal Revenue Service Form W-8BEN or Form W-8BEN-E or Form W-8ECI as set forth
in clause (i) above, or (x) a certificate in substantially the form of Schedule II (any such certificate, a “Schedule II Certificate”) and (y) two accurate and complete original signed copies of Internal
Revenue Service Form W-8BEN or Form W-8BEN-E (or successor form) certifying such Lender’s entitlement to an exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any
Revolving Credit Note. In addition, each Lender agrees that it will deliver upon the Borrower’s request updated versions of the foregoing, as applicable, whenever the previous certification has become obsolete or inaccurate in any material
respect, together with such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or reduction in United States withholding tax with respect to payments under this Agreement and
any Revolving Credit Note. Notwithstanding anything to the contrary contained in this Section 4.04(a), but subject to the immediately 

  
 35 

 
succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold Taxes imposed by the United States (or any political subdivision
or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. federal
income tax purposes to the extent that such Lender has not provided to the Borrower U.S. Internal Revenue Service Forms that establish a complete exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant
to this Section 4.04(a) to gross-up payments to be made to a Lender in respect of Taxes imposed by the United States if (I) such Lender has not provided to the Borrower the Internal Revenue Service Forms required to be provided to the
Borrower pursuant to this Section 4.04(a) or (II) in the case of a payment, other than interest, to a Lender described in clause (ii) above, to the extent that such Forms do not establish a complete exemption from withholding of such
Taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this Section 4.04, the Borrower agrees to pay additional amounts and to indemnify each Lender in the manner set forth in this
Section 4.04(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect of any amounts deducted or withheld by it as described in the immediately preceding sentence as a result of any changes after
the Effective Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of Taxes. 

(b)    Additional Costs. Subject to Sections 4.04(c), (d) and (e): 

(i)    Without duplication of any amounts payable described in Section 3.03(c) or 4.03(a), if after
the date hereof, any Regulatory Change shall (1) impose, modify or deem applicable any reserve, special deposit or similar requirement against any Lender’s Commitment or Loans, (2) subject the Administrative Agent or any Lender to any
Taxes (other than (A) Indemnified Taxes, (B) Excluded Taxes (other than Taxes measured by the overall capital or net worth of the Administrative Agent or such Lender) and (C) Other Connection 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 such Lender’s Applicable Lending Office) any other condition regarding this
Agreement, its Commitment or the Loans and the result of any event referred to in clause (1), (2) or (3) shall be to increase the cost to such Lender (or such Lender’s Applicable Lending Office) of maintaining its Commitment or any
Eurodollar Loans made by such Lender (which increase in cost shall be calculated in accordance with such Lender’s reasonable averaging and attribution methods) by an amount which such Lender deems to be material, then, upon demand by such
Lender, the Borrower shall pay to the Administrative Agent or such Lender, as the case may be, on demand, an amount equal to such increase in cost; and 

(ii)    Without duplication of any amounts payable described in Section 3.03(c) or 4.03(a), if any
Lender shall have determined that any Regulatory Change 

  
 36 

 
relating to capital adequacy or liquidity (including any Regulatory Change made prior to the date hereof but not effective until after the date hereof), or compliance by such Lender (or such
Lender’s Applicable Lending Office) with any Regulatory Change regarding capital adequacy or liquidity (whether or not having the force of law), has or would have the effect of, reducing the rate of return on capital for such Lender (or such
Lender’s Applicable Lending Office) or any corporation controlling such Lender as a consequence of its obligations under this Agreement to a level below that which such Lender (or such Lender’s Applicable Lending Office) or such
corporation could have achieved but for such Regulatory Change (taking into consideration such Lender’s (or such Lender’s Applicable Lending Office) or such corporation’s policies with respect to capital adequacy or liquidity), then
from time to time, upon demand by such Lender, the Borrower shall pay to such Lender, on demand, such additional amount or amounts as will compensate such Lender (or such Lender’s Applicable Lending Office) or such corporation for such
reduction. 
 (c)    Lending Office Designations. Before making any demand for payment pursuant
to this Section 4.04, each Lender shall, if possible, designate a different Applicable Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Lender, be otherwise disadvantageous to
such Lender. 
 (d)    Certificate, Etc. In connection with any demand for payment pursuant to
this Section 4.04, a Lender shall provide to the Borrower, with a copy to the Administrative Agent, a certificate, signed by an officer of such Lender, setting forth in reasonable detail the basis for such demand, the amount required to be paid
by the Borrower to such Lender and the computations made by such Lender to determine such amount. 

(e)    Limitations; Delay in Requests. The Borrower shall not be obligated to compensate a
Lender for any amount under Section 4.04(b) arising or occurring more than (i) 90 days prior to the date on which an office of such Lender primarily responsible for the administration of this Agreement obtains actual knowledge that such
Lender is entitled to such compensation or (ii) nine months prior to the date that such Lender notifies the Borrower of the Regulatory Change giving rise to such increased costs or reductions, and of such Lender’s intention to claim
compensation therefor (except that, if the Regulatory Change 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). 

(f)    FATCA. If a payment made to a Lender under any Credit Document would be subject to U.S.
federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), to the extent reasonably
possible, such Lender shall deliver to the Borrower and the Administrative 

  
 37 

 
Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower 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 the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their
obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 4.04(f),
“FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

(g)    Cooperation. The Borrower agrees, upon the request of the Administrative Agent or any
Lender, promptly to execute, deliver and complete such forms, certificates and other documents, make such filings and otherwise cooperate with the Administrative Agent or such Lender, in each case as the Administrative Agent or such Lender may
reasonably request from time to time, in order for the Administrative Agent or such Lender to establish that the Administrative Agent or such Lender is not subject to, or is entitled to a reduction in the amount of or exemption from, any deduction,
withholding or other Taxes with respect to any payments to the Administrative Agent or such Lender for principal, interest, fees or other amounts under the Credit Documents, including United Kingdom HM Revenue & Customs’ Form DTTP2.

 Section 4.05    Funding Impracticable. 

If at any time any Lender shall have determined in good faith (which determination shall be conclusive) that the making or
maintenance of all or any part of such Lender’s Eurodollar Loans has been made impracticable or unlawful because of compliance by such Lender in good faith with any law or guideline or interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration thereof or with any request or directive of such body (whether or not having the effect of law) or because U.S. dollar deposits in the amount and requested maturity of such
Eurodollar Loans are not available to such Lender in the London Eurodollar interbank market, then the Administrative Agent, upon notification to it of such determination by such Lender, shall forthwith advise the other Lenders and the Borrower
thereof. Upon such date as shall be specified in such notice and until such time as the Administrative Agent, upon notification to it by such Lender, shall notify the Borrower and the other Lenders that the circumstances specified by it in such
notice no longer apply, (i) notwithstanding any other provision of this Agreement, such Eurodollar Loans shall, automatically and without requirement of further notice, or any payment pursuant to Section 4.03 or 4.04, by the Borrower, be
converted to ABR Loans, and (ii) the obligation of such Lender to make or continue Eurodollar Loans shall be suspended, and, if the Borrower shall request in a Borrowing Request or Conversion Request that the Lenders make a Eurodollar Loan, the
Loan requested to be made by such Lender shall instead be made as an ABR Loan. 

  
 38 

 Section 4.06    Expenses; Indemnity; Damage
Waivers. 
 (a)    The Borrower agrees, whether or not any Loan is made, to pay or reimburse the
Administrative Agent all of its reasonable out-of-pocket fees and expenses incurred in connection with the development, preparation, negotiation, execution, closing and
syndication of, the Credit Documents and the administration of the credit facility established under the Credit Documents and any amendment, supplement or modification thereto (whether or not executed or effective) and any documents prepared in
connection therewith, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent and the maintenance of an electronic platform (including without limitation charges of Debtdomain or any similar
electronic information platform)) or information transmission systems in connection with this Agreement. 

(b)    The Borrower agrees to pay all reasonable out-of-pocket fees and expenses incurred by the Administrative Agent and, after the occurrence and during the continuance of an Event of Default, the Joint Lead Arrangers, the Joint Bookrunners or any Lender
(including, without limitation, the reasonable fees and disbursements of one counsel to the Administrative Agent, unless (and to the extent) conflicts of interest require the use of more than one counsel) in connection with the enforcement of, and
the protection of their respective rights under, any provision of any Credit Document or any amendment or supplement to this Agreement (including all such fees and expenses incurred during any “workout” or restructuring in respect of the
Obligations and during any legal proceeding, including any bankruptcy proceeding). 
 (c)    The
Borrower agrees to indemnify the Administrative Agent, the Joint Lead Arrangers, the Joint Bookrunners, each of the Lenders and each of their respective Affiliates and their respective directors, officers, employees, agents and advisors (each, an
“Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including counsel fees and expenses, incurred by or asserted against any Indemnitee arising out
of, in any way connected with, or as a result of (i) the execution or delivery of any Credit Document or any agreement or instrument contemplated by any Credit Document, the performance by the parties thereto of their respective obligations
under any Credit Document or the consummation of the transactions contemplated by any Credit Document, (ii) the use of the proceeds of the Loans or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing,
whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee. In connection with any claim for indemnification pursuant to this Agreement by more than one Indemnitee,
all such Indemnitees shall be represented by the same legal counsel selected by the Indemnitees; provided that if such legal counsel determines in good faith that representing all such Indemnitees is reasonably likely to result in a
conflict of interest under laws or ethical 

  
 39 

 
principles applicable to such legal counsel or that a defense or counterclaim is available to an Indemnitee that is not available to all such Indemnitees, then to the extent reasonably necessary
to avoid such a conflict of interest or to permit unqualified assertion of such a defense or counterclaim, each Indemnitee shall be entitled to separate representation. 

(d)    All amounts due under this Section 4.06 shall be payable in immediately available funds upon
written demand therefor. 
 (e)    To the fullest extent permitted by applicable law, the Borrower shall
not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of,
this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan, or the use of the proceeds thereof. No Indemnitee referred to in paragraph (c) above shall be
liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the
other Loan Documents or the transactions contemplated hereby or thereby. 

Section 4.07    Survival. 

The provisions of Sections 4.03, 4.04, 4.06 and 9.06, shall remain operative and in full force and effect regardless of the
expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the reduction or termination of any Commitments, the invalidity or unenforceability of any term or provision of
any Credit Document, or any investigation made by or on behalf of the Lenders. 

Section 4.08    Replacement of a Lender. 

Notwithstanding anything to the contrary contained herein, if any Lender shall request compensation pursuant to
Section 4.04(b)(i) or (ii) then, in each case, the Borrower may require that such Lender transfer all of its right, title and interest under this Agreement and such Lender’s Revolving Credit Notes to one or more of the other Lenders
or any other lender identified by the Borrower and reasonably acceptable to the Administrative Agent as a Replacement Lender which is willing to assume all of the obligations of such Lender, for consideration equal to the outstanding principal
amount of such Lender’s Loans, together with interest thereon to the date of such transfer and all other amounts payable under the Credit Documents to such Lender on or prior to the date of such transfer (including, without limitation, any fees
accrued hereunder and any amounts which would be payable under Section 4.03 as if all of such Lender’s Loans were being prepaid in full on such date). Subject to the execution and delivery of new notes, an Assignment and Acceptance, and
such other documents as such Lender may 

  
 40 

 
reasonably require, such Replacement Lender shall be a “Lender” for all purposes hereunder. Without prejudice to the survival of any other agreement of the Borrower hereunder, the
agreements of the Borrower contained in Sections 4.04 and 4.06 (without duplication of any payments made to such Lender by the Borrower or the Replacement Lender) shall survive for the benefit of any Lender replaced under this Section 4.08 with
respect to the time prior to such replacement.

tax under the provisions of Section 501 of the Code, and to the best 

  
 42 

 
knowledge of the Borrower, nothing has occurred which would cause the loss of such qualification or tax-exempt status. 

(iii)    There is no material outstanding liability under Title IV of ERISA (other than the liability of
the Plan to pay benefits) with respect to any Plan maintained or sponsored by the Borrower or any ERISA Affiliate (as to which the Borrower is or may be liable), or with respect to any Plan to which the Borrower or any ERISA Affiliate (wherein the
Borrower is or may be liable) contributes or is obligated to contribute.

Plans has any Unfunded Pension Liability in excess of ten percent (10%) of the Net Worth as to which the Borrower is or may be liable.

or sponsored by the Borrower or to which the Borrower is obligated to contribute. 
 (vi)    There are
no pending or, to the best knowledge of the Borrower, threatened claims, actions or lawsuits, other than routine claims for benefits in the usual and ordinary course, asserted or instituted against (i) any Plan maintained or sponsored by the
Borrower or its assets, (ii) any ERISA Affiliate with respect to any Qualified Plan of the Borrower, or (iii) any fiduciary with respect to any Plan for which the Borrower may be directly or indirectly liable, through indemnification
obligations or otherwise, which would be reasonably likely to have a Material Adverse Effect. 

(vii)    The Borrower has not incurred nor reasonably expects to incur (i) any liability (and no
event has occurred which, with the giving of notice under Section 4219 of ERISA, would result in such liability) under Section 4201 or 4243 of ERISA with respect to a Multiemployer Plan or (ii) any liability under Title IV of ERISA
(other than premiums due and not delinquent under Section 4007 of ERISA) with respect to a Qualified Plan except for liability that would not be reasonably expected to have a Material Adverse Effect.

and payable except (a) those which are being contested in good faith by appropriate proceedings and for which adequate reserves have been provided in accordance with GAAP, and (b) those levied or imposed on Subsidiaries other than
Significant Subsidiaries the nonpayment of which would not, in the aggregate, have a Material Adverse Effect. To the best knowledge of the Borrower, there is no proposed tax assessment against the Borrower or any of its Subsidiaries which would, if
the assessment were made, have a Material Adverse Effect. 
 (k)    Financial Condition. 

The audited consolidated balance sheet of SGC and its consolidated Subsidiaries as of December 31, 2016 and the related
consolidated statements of income, changes in shareholders’ equity and cash flows for the period then ended, copies of which have been furnished to the Administrative Agent and the Lenders, fairly present the consolidated financial condition of

good standing, and the Borrower and each of its Subsidiaries are in 

  
 44 

 
compliance with all terms and conditions of such Environmental Permits, except where the failure so to obtain, be in good standing or be in compliance would not have a Material Adverse Effect.

 (iii)    None of the Borrower, any of its Subsidiaries or any of their present Property or
operations is subject to any outstanding written order from or agreement with any Governmental Authority or other Person, nor subject to any judicial or docketed administrative proceeding, respecting any Environmental Law, Environmental Claim or
Hazardous Material which would have a Material Adverse Effect. 
 (iv)    There are no conditions or
circumstances which may give rise to any Environmental Claim arising from the operations of the Borrower or its Subsidiaries which would have a Material Adverse Effect. Without limiting the generality of the foregoing, except as would not, in the

leaking or disposing of Hazardous Materials offsite and (ii) the Borrower and its Subsidiaries have notified all of their employees of the existence, if any, of any health hazard arising from the conditions of their employment and have met all

“Investment Company” within the meaning of the Investment Company Act of 1940.

or any of its Subsidiaries or, to the best of the Borrower’s knowledge, threatened against or affecting the Borrower or any of its Subsidiaries which would have a Material Adverse Effect, and no significant unfair labor practice complaint is
pending against the Borrower or any of its Subsidiaries or, to the best knowledge of the Borrower, threatened against any of them before any Governmental Authority which would have a Material Adverse Effect.

financially sound and reputable insurance companies, in such amounts, with such deductibles and covering such risks as is customarily carried by companies engaged in similar businesses and owning similar Property in localities where the Borrower or
such Significant Subsidiary operates. 
 (p)    Full Disclosure. None of the representations or
warranties made by the Borrower in this Agreement as of the date of such representations and warranties, and none of the statements contained in any certificate furnished by or on behalf of the Borrower in connection with this Agreement contains any
untrue statement of a material 

  
 45 

 
fact or omits any material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they are made, not misleading. 

(q)    Compliance with Applicable Laws. Neither the Borrower nor any Subsidiary is in default with
respect to any judgment, order, writ, injunction, decree or decision of any Governmental Authority which default would have a Material Adverse Effect. The Borrower and each Subsidiary is complying in all material respects with all applicable
statutes and regulations, including ERISA and applicable occupational, safety and health and other labor laws, of all Governmental Authorities, a violation of which would have a Material Adverse Effect. 

(r)    Ranking. The Obligations of the Borrower to the Lenders to be undertaken under the Credit
Documents rank senior to or pari passu with other Unsecured Debt of the Borrower. 

(s)    Anti-Corruption Laws and Anti-Terrorism Laws.

at all times in compliance with all applicable Anti-Corruption Laws and Anti-Terrorism Laws and no action, suit or proceeding by or before any Governmental Authority involving the Borrower or any of its Subsidiaries with respect to any potential
violation of the Anti-Corruption Laws or Anti-Terrorism Laws is pending, or to the knowledge of the Borrower threatened. The Borrower has provided to the Administrative Agent and the Lenders all information regarding the Borrower and its
Subsidiaries and its Affiliates necessary for the Bank to comply with “know your customer” and Anti-Terrorism Laws and such information is correct.

opinion of the Required Lenders) to exceed the fair market value of such Qualified Plan’s assets allocable to such benefits, all determined as of the most recent valuation date for each such Qualified Plan; provided, however that
any liability of $25,000,000 or less shall not be considered “material” for purposes of this Section 7.02(e).

(g)    Restricted Payments. Declare or make any dividend payment or other distribution of assets,
Property, cash, rights, obligations or securities on account of any shares of any class of its capital stock or purchase, redeem or otherwise acquire for value (or permit any of its non-wholly-owned Subsidiaries to do so) any shares of its capital
stock or any warrants, rights or options to acquire such shares, now or hereafter outstanding if a Default or Event of Default has occurred and is continuing or would result therefrom. 

(h)    Change in Business. Engage, or permit any of its Subsidiaries to engage, in any material
line of business substantially different from those lines of business carried on by it on the date hereof and any and all reasonably related businesses necessary for, in support, furtherance or anticipation of and/or ancillary to or in the
preparation for such businesses. 
 (i)    Use of Proceeds. Use the proceeds of any Loan other
than to fund fees and expenses associated with this Agreement and for general corporate purposes. Without limiting the foregoing, the Borrower will not, directly or knowingly indirectly, use the proceeds of any advance, or lend, contribute or
otherwise make available such proceeds, to any subsidiary, joint venture partner or other Person (A) to fund any activities or business of or with any Person, or in any country or territory, that at the time

  
 56 

 
of such funding, is, or whose government is, the subject of Sanctions, (B) in any other manner that would result in a violation of Sanctions by any Person including, without limitation, the
Borrower, the Lenders and the Administrative Agent or (C) in furtherance of an offer, payment, promise to pay, or authorization of the payment or giving of money, or anything else of value, to any Person in violation of any Anti-Corruption
Laws. 
 Section 7.03    Financial Covenant. 

Until satisfaction in full of all the obligations of the Borrower under the Credit Documents and termination of the

 ARTICLE IX

 THE ADMINISTRATIVE AGENT 

Section 9.01    The Agency. 

Each Lender appoints The Bank of New York Mellon as its agent hereunder and irrevocably authorizes the Administrative Agent to
take such action on its behalf and to exercise such powers hereunder as are specifically delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto, and the Administrative Agent hereby
accepts such appointment subject to the terms hereof. The relationship between the Administrative Agent and the Lenders shall be that of agent and principal only and nothing herein shall be construed to constitute the Administrative Agent a trustee
or fiduciary for any Lender nor to impose on the Administrative Agent duties or obligations other than those expressly provided for herein. 

Section 9.02    The Administrative Agent’s Duties. 

The Administrative Agent shall promptly forward to each Lender copies, or notify each Lender as to the contents, of all
notices received from the Borrower pursuant to the terms of this Agreement and, in the event that the Borrower fails to pay when due the principal of or interest on any Loan, the Administrative Agent shall promptly give notice thereof to the
Lenders. As to any other matter not expressly provided for herein, the Administrative Agent shall have no duty to act or refrain from acting with respect to the Borrower, except upon the instructions of the Required Lenders. The Administrative Agent
shall not be bound by any waiver, amendment, supplement, or modification of this Agreement which affects its duties hereunder, unless it shall have given its prior written consent thereto. The Administrative Agent shall have no duty to ascertain or
inquire as to the performance or observance of any of the terms, conditions, covenants or agreements binding on the Borrower pursuant to this Agreement nor shall the Administrative Agent be deemed to have knowledge of the occurrence of any Default
or Event of Default (other than a failure of the Borrower to pay when due the principal or interest on any Loan), unless it shall have received written notice from the Borrower or a Lender specifying such Default or Event of Default and stating that
such notice is a “Notice of Default”. 

  
 60 

 Section 9.03    Limitation of Liabilities. 

Each of the Lenders and the Borrower agree that (i) neither the Administrative Agent nor any of its officers or employees
shall be liable for any action taken or omitted to be taken by any of them hereunder except for its or their own gross negligence or willful misconduct as determined by a final and nonappealable ruling by a court of competent jurisdiction,
(ii) neither the Administrative Agent nor any of its officers or employees shall be liable for any action taken or omitted to be taken by any of them in good faith in reliance upon the advice of counsel, independent public accountants or other
experts selected by the Administrative Agent, and (iii) the Administrative Agent shall be entitled to rely upon any notice, consent, certificate, statement or other document believed by it to be genuine and correct and to have been signed
and/or sent by the proper Persons. 
 Section 9.04    The Administrative Agent as a Lender.

 The Administrative Agent may maintain deposits or credit balances for, invest in, lend money to and generally engage in
any kind of banking business with the Borrower or any Subsidiary or Affiliate of the Borrower without any duty to account therefor to the Lenders. 

Section 9.05    Lender Credit Decision. 

Neither the Administrative Agent, nor any of its Affiliates, officers or employees has any responsibility for, gives any
guaranty in respect of, nor makes any representation to the Lenders as to, (i) the condition, financial or otherwise, of the Borrower or any Subsidiary thereof or the truth of any representation or warranty given or made in this Agreement, or
in connection herewith or (ii) the validity, execution, sufficiency, effectiveness, construction, adequacy, enforceability or value of this Agreement or any other document or instrument related hereto. Except as specifically provided herein,
neither the Administrative Agent nor any of its Affiliates, officers or employees shall have any duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect to the
operations, business, property, condition or creditworthiness of the Borrower or any of its Subsidiaries, whether such information comes into the Administrative Agent’s possession on or before the date hereof or at any time thereafter. Each
Lender acknowledges that (i) it has, independently and without reliance upon the Administrative Agent or any other Lender, based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement and (ii) all information reviewed by it in its credit analysis or otherwise in connection herewith has been provided solely by or on behalf of the Borrower, and the Administrative Agent has no responsibility for such
information. Each Lender also acknowledges that it will independently and without reliance upon the Administrative Agent or any other Lender, based on such documents and information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under any Credit Document. 

  
 61 

 Section 9.06    Indemnification. 

Each Lender agrees to indemnify the Administrative Agent, to the extent not reimbursed by the Borrower, ratably in proportion
to its Commitment, from and against any and all liabilities, obligations, losses, claims, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or
asserted against the Administrative Agent in any way relating to or arising out of this Agreement, or any action taken or omitted to be taken by the Administrative Agent hereunder; provided, that no Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Administrative Agent or any of its officers or employees as determined
by a final and nonappealable ruling by a court of competent jurisdiction. Without limiting the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including fees and disbursements of counsel incurred by the Administrative Agent) in connection with the preparation, execution or enforcement of, or legal advice in respect of rights
or responsibilities under, any Credit Document or any amendments or supplements thereto, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower. Except for action expressly required of the Administrative
Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall receive further assurances to its satisfaction from the Lenders of their indemnification obligations under this
Section 9.06 against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. 

Section 9.07    Successor Administrative Agent 

The Administrative Agent may resign at any time by giving 30 days’ prior written notice thereof (unless the parties agree
otherwise) to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent reasonably acceptable to the Borrower. If no successor Administrative Agent shall have been
so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the resigning Administrative Agent’s giving of notice of resignation, the resigning Administrative Agent may appoint a successor Administrative
Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of its appointment as
Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigned Administrative Agent, and the
resigned Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any Administrative Agent’s resignation, the provisions of this 

  
 62 

 
Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. 

Section 9.08    No Duty Regarding Discretionary Actions 

The Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except
discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as
shall be expressly provided for herein or in the other Credit Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to
liability or that is contrary to any Credit Document or applicable law. 

Section 9.09    Syndication and Other Agents 

Notwithstanding anything herein to the contrary, the Joint Lead Arrangers, the Joint Bookrunners and the Co-Syndication Agents
named on the cover page of this Agreement shall not have any duties or liabilities under this Agreement, except in their respective capacities, if any, as Lenders. 

ARTICLE X 
 EVIDENCE
OF LOANS; TRANSFERS 
 Section 10.01    Evidence of Loans; Revolving Credit Notes.

 The Borrower’s obligation to repay the Loans shall be evidenced by Revolving Credit Notes if requested by each
Lender, one such payable to the order of each such Lender. The Revolving Credit Note of each Lender shall (i) be in the principal amount of such Lender’s Commitment, (ii) be dated the Effective Date (or the effective date on which
such Lender becomes a Lender hereunder) and (iii) be stated to mature on the Termination Date and bear interest from its date until maturity on the principal balance (from time to time outstanding thereunder) payable at the rates and in the
manner provided herein. Each Lender is authorized to indicate upon the grid attached to its Revolving Credit Note all Loans made by it pursuant to this Agreement, interest elections and payments of principal and interest thereon. Such notations
shall be presumptive, absent manifest error, as to the aggregate unpaid principal amount of all Loans made by such Lender, and interest due thereon, but the failure by any Lender to make such notations or the inaccuracy or incompleteness of any such
notations shall not affect the obligations of the Borrower hereunder or under the Revolving Credit Notes. 

  
 63 

 Section 10.02    Participations. 

(a)    Any Lender may at any time grant to one or more financial institutions (but not to a natural
Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person, or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each a “Participant”)
participating interests in its Commitment or any or all of its Loans. In the event of any such grant by a Lender of a participating interest to a Participant, whether or not upon notice to the Borrower and the Administrative Agent, such Lender shall
remain responsible for the performance of its obligations hereunder, and, except to the extent such participating interest has been granted pursuant to Section 4.02(e), the Borrower and the Administrative Agent shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which any Lender may grant such a participating interest shall provide that such Lender shall retain the sole
right and responsibility to enforce the obligations of the Borrower hereunder including the right to approve any amendment, modification or waiver of any provision of this Agreement; provided, that such participation agreement may provide
that such Lender will not agree to any modification, amendment or waiver of this Agreement described in clauses (i) through (vi), inclusive, of Section 11.06(b) without the consent of the Participant. 

(b)    Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary
agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under this Agreement (the
“Participant Register”); provided that no Lender shall have any obligation to disclose any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a
Participant’s interest in any Commitments, Loans, or its other obligations under this Agreement) except to the extent that such disclosure is necessary to establish that such Commitment, Loan, 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, 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. 

(c)    The Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.03 and
4.04(b) (subject to the requirements and limitations in Section 4.04, including the requirements under Section 4.04(a) (it being understood that the documentation required under Section 4.04(a) 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 Section 10.03; provided that such Participant (A) agrees to be subject to the provisions of Section 4.08 as if it were
an assignee under Section 10.03; and (B) shall not be entitled to receive any greater payment under Section 4.04(b), with respect to any participation, than its participating Lender would have been entitled to

  
 64 

 
receive, except to the extent such entitlement to receive a greater payment results from a Regulatory Change that occurs after the Participant acquired the applicable participation. 

(d)    To the extent permitted by law, each Participant also shall be entitled to the benefits of
Section 11.04 as though it were a Lender; provided that such Participant agrees to be subject to Section 4.02(e) as though it were a Lender. 

Section 10.03    Assignments. 

(a)    Any Lender may at any time assign to one or more financial institutions (but not to a natural
Person, or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person, or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each an “Assignee”), other
than a Defaulting Lender or a subsidiary thereof or any financial institution who, upon becoming a Lender hereunder, would constitute a Defaulting Lender or a subsidiary thereof, all, or a proportionate part of all, of its rights and obligations
under this Agreement, and such Assignee shall assume such rights and obligations, pursuant to an instrument, in substantially the form of Exhibit E (an “Assignment and Acceptance”), executed by such Assignee and such
transferring Lender, with (and subject to) the signed consent of the Borrower (which consent shall not be unreasonably withheld or delayed and which consent shall be deemed to have been given if the Borrower has not responded within ten Business
Days of its receipt of a written request for such consent) and the Administrative Agent (which consent shall not be unreasonably withheld); provided that (i) each such assignment (other than assignments (x) to its Affiliates or
(y) its entire interest) shall be in a minimum amount of $10,000,000 or in integral multiples of $1,000,000 in excess thereof (unless otherwise approved by the Administrative Agent in its sole discretion), (ii) each assignee shall be an
Eligible Institution, and (iii) after giving effect to each such assignment, the Commitment of the assignor (if it has not assigned its entire interest) and of the assignee shall be at least $5,000,000; provided further, that the
foregoing consent requirement shall not be applicable in the case of an assignment or other transfer by any Lender to an Affiliate of such Lender or to another Lender; provided further, that any consent of the Borrower otherwise required
under this Section shall not be required if an Event of Default has occurred and is continuing. Upon execution and delivery of an Assignment and Acceptance and payment by such Assignee to such transferring Lender of an amount equal to the purchase
price agreed between such transferring Lender and such Assignee and payment by the transferring Lender or the Assignee of an assignment fee of $4,500 (or $7,500, if the transferring Lender is a Defaulting Lender) to the Administrative Agent (unless
such fee is waived by the Administrative Agent in its sole discretion), such Assignee shall be a Lender party to this Agreement and shall have all the rights and obligations of a Lender with a Commitment as set forth in such Assignment and
Acceptance, and the transferring Lender shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. 

  
 65 

 (b)    No Assignee of any transferring Lender’s rights
shall be entitled to receive any greater payment under Section 4.03 or 4.04 than such Lender would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower’s prior written consent
or by reason of the provisions of Section 4.04(c) requiring such transferring Lender to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such payment did not exist.

 (c)    The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall
maintain at one of its offices in the United States a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of 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, and the Borrower, the Administrative Agent and the Lenders may 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, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable
time and from time to time upon reasonable prior notice. 
 Section 10.04    Certain
Pledges. 
 Notwithstanding any other provision in this Agreement, any Lender may at any time create a security interest
in, or pledge, all or any portion of its rights under this Agreement and any Revolving Credit Note held by it in favor of any Federal Reserve Bank in accordance with Federal Reserve Board Regulation A (or any successor provision) or U.S. Treasury
Regulation 31 C.F.R. § 203.14 (or any successor provision), and such Federal Reserve Bank may enforce such pledge or security interest in any manner permitted under applicable law.

Section 3. Representations and Warranties of the Assignor. The Assignor (i) represents and warrants that, as of
the date hereof, it is the legal and beneficial owner of the interest being assigned by it hereunder and that such interest is held by it free and clear of any adverse claim; (ii) makes no representation or warranty and assumes no
