 (1)
    the sum of: (a) Term SOFR and (b) the related Benchmark Replacement Adjustment;

notwithstanding anything to the contrary in this Agreement or in any other Loan Document, upon the occurrence of a Term SOFR Transition Event, and the delivery of a Term SOFR Notice, on the applicable Benchmark Replacement Date the “Benchmark
Replacement” shall revert to and shall be deemed to be the sum of (a) Term SOFR and (b) the related Benchmark Replacement Adjustment, as set forth in clause (1) of this definition (subject to the first proviso above). 

If the Benchmark Replacement as determined pursuant to clause (1), (2) or (3) above would be less than the Floor, the
Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents. 

“Benchmark Replacement Adjustment” means, with respect to any replacement of the then-current Benchmark with
an Unadjusted Benchmark Replacement for any applicable Interest Period and Available Tenor for any setting of such Unadjusted Benchmark Replacement:

adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that has been selected or
recommended by the Relevant Governmental Body for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for the applicable Corresponding Tenor; 

  
 3 

 (b) the spread adjustment (which may be a positive or negative value or
zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that would apply to the fallback rate for a derivative transaction referencing the ISDA Definitions to be effective upon an index cessation event with
respect to such Benchmark for the applicable Corresponding Tenor; and 
 (2)     for purposes of clause
(3) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Administrative
Agent and the Borrower for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such
Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or (ii) any evolving or then-prevailing market convention for determining a spread adjustment, or
method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for dollar-denominated syndicated credit facilities; 

provided that, in the case of clause (1) above, such adjustment is displayed on a screen or other information
service that publishes such Benchmark Replacement Adjustment from time to time as selected by the Administrative Agent in its reasonable discretion. 

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical,
administrative or operational changes (including changes to the definition of “Alternate Base Rate,” the definition of “Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and
making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the
Administrative Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Administrative Agent in a manner substantially consistent with market practice
(or, if the Administrative Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Administrative Agent determines that no market practice for the administration of such Benchmark Replacement
exists, in such other manner of administration as the Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents). 

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the
then-current Benchmark: 
 (1)     in the case of clause (1) or (2) of the definition of
“Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of such Benchmark (or the published component used in
the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof); 

  
 4 

 (2)     in the case of clause (3) of the definition
of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein; or

Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, so long as the Administrative Agent has not received, by 5:00 p.m. (New York City time) on the fifth (5th) Business
Day after the date notice of such Early Opt-in Election is provided to the Lenders, written notice of objection to such Early Opt-in Election from Lenders comprising the
Required Lenders. 
 For the avoidance of doubt, (i) if the event giving rise to the Benchmark Replacement Date occurs
on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination and (ii) the “Benchmark Replacement
Date” will be deemed to have occurred in the case of clause (1) or (2) with respect to any Benchmark upon the occurrence of the applicable event or events set forth therein with respect to all then-current Available Tenors of such
Benchmark (or the published component used in the calculation thereof).

Benchmark (or such component), which states that the administrator of such Benchmark (or such component) has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof) permanently or indefinitely, provided
that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof); or 

(3)     a public statement or publication of information by the regulatory supervisor for the administrator
of such Benchmark (or the published component used in the calculation thereof) announcing that all Available Tenors of such Benchmark (or such component thereof) are no longer representative. 

  
 5 

 For the avoidance of doubt, a “Benchmark Transition Event” will be

calculation thereof). 
 “Benchmark Unavailability Period” means the period (if any) (x) beginning at
the time that a Benchmark Replacement Date pursuant to clauses (1) or (2) of that definition has occurred if, at such time, no Benchmark Replacement has replaced the then-current Benchmark for all purposes hereunder and under any Loan Document

 (1)    a notification by the Administrative Agent to (or the request by
the Borrower to the Administrative Agent to notify) each of the other parties hereto that at least five currently outstanding dollar-denominated syndicated credit facilities at such time contain (as a result of amendment or as originally executed) a
SOFR-based rate (including SOFR, a term SOFR or any other rate based upon SOFR) as a benchmark rate (and such syndicated credit facilities are identified in such notice and are publicly available for review), and

for such Business Day published by the SOFR Administrator on the SOFR Administrator’s Website at approximately 8:00 a.m. (New York City time) on the immediately succeeding Business Day. 

“SOFR Administrator” means the NYFRB (or a successor administrator of the secured overnight financing rate).

 “Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark,
as applicable, any tenor for such Benchmark or payment period for interest calculated with reference to such Benchmark, as applicable, that is or may be used for determining the length of an Interest Period pursuant to this Agreement as of such date
and not including, for the avoidance of doubt, any tenor for such Benchmark that is then-removed from the definition of “Interest Period” pursuant to clause (f) of Section 2.14. 

“Benchmark” means, initially, the LIBO Rate; provided that if a Benchmark Transition Event, a Term SOFR
Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred with respect to the LIBO Rate or the then-current Benchmark, then “Benchmark”
means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant to clause (b) or clause (c) of Section 2.14. 

“Daily Simple SOFR” means, for any day, SOFR, with the conventions for this rate (which will include a
lookback) being established by the Administrative Agent in accordance with the conventions for this rate selected or recommended by the Relevant Governmental Body for determining “Daily Simple SOFR” for business loans; provided,

 “SOFR Administrator’s Website” means the Federal Reserve Bank of
New York’s Website, currently at http://www.newyorkfed.org, or any successor source for the secured overnight financing rate identified as such by the SOFR Administrator from time to time. 

  
 7 

 “Term SOFR Notice” means a notification by the
Administrative Agent to the Lenders and the Borrower of the occurrence of a Term SOFR Transition Event. 
 “Term SOFR
Transition Event” means the determination by the Administrative Agent that (a) Term SOFR has been recommended for use by the Relevant Governmental Body, (b) the administration of Term SOFR is administratively feasible for the
Administrative Agent and (c) a Benchmark Transition Event or an Early Opt-in Election, as applicable, has previously occurred resulting in a Benchmark Replacement in accordance with
Section 2.14 that is not Term SOFR. 
 (xii)    Section 1.05 of the Existing
Credit Agreement is amended and restated in its entirety as follows: 
 Interest Rates; LIBOR Notification. The
interest rate on Eurodollar Loans is determined by reference to the LIBO Rate, which is derived from the London interbank offered rate.    The London interbank offered rate is intended to represent the rate at which contributing
banks may obtain short-term borrowings from each other in the London interbank market. In July 2017, the U.K. Financial Conduct Authority announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate
submissions to the ICE Benchmark Administration (together with any successor to the ICE Benchmark Administrator, the “IBA”) for purposes of the IBA setting the London interbank offered rate. As a result, it is possible that
commencing in 2022, the London interbank offered rate may no longer be available or may no longer be deemed an appropriate reference rate upon which to determine the interest rate on Eurodollar Loans. In light of this eventuality, public and private
sector industry initiatives are currently underway to identify new or alternative reference rates to be used in place of the London interbank offered rate. Upon the occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early
Opt-In Election, Section 2.14(b) and (c) provide the mechanism for determining an alternative rate of interest. The Administrative Agent will promptly notify the Borrower,
pursuant to Section 2.14(e), of any change to the reference rate upon which the interest rate on Eurodollar Loans is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not
have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the definition of “LIBO Rate” or with respect to any alternative or successor rate
thereto, or replacement rate thereof (including, without limitation, (i) any such alternative, successor or replacement rate implemented pursuant to Section 2.14(b) or (c), whether upon the occurrence of a
Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, and (ii) the implementation of any Benchmark Replacement Conforming Changes pursuant to
Section 2.14(d)), including without limitation, whether the composition or characteristics of any such alternative, successor or replacement reference rate will be similar to, or produce the same value or economic
equivalence of, the LIBO Rate or have the same volume or liquidity as did the London interbank offered rate prior to its discontinuance or unavailability. 

(xiii)    Section 2.03 of the Existing Credit Agreement is amended and restated in its entirety as follows:

 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request
by telephone (a) in the case of a Eurodollar 

  
 8 

 
Borrowing, not later than 11:00 a.m., New York City time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New
York City time, on the date of the proposed Borrowing. Each such Borrowing Request shall be irrevocable and shall be signed by a Responsible Officer of the Borrower. Each such Borrowing Request shall specify the following information in compliance
with Section 2.02: 
 (i)    the aggregate amount of the requested Borrowing;

 (ii)    the date of such Borrowing, which shall be a Business Day; 

(iii)    whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; 

(iv)    in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which
shall be a period contemplated by the definition of the term “Interest Period”; 
 (v)    the
location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.06; and 

(vi)    whether such Loan shall be due on the 364th
date after such Loan is made. 
 If no election as to the Type of Borrowing is specified, then the requested Borrowing shall
be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. If no election as to the maturity of a
Loan is specified, then such Loan shall be due on the Maturity Date. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of
such Lender’s Loan to be made as part of the requested Borrowing. 
 (xiv)    Section 2.10(a) of the
Existing Credit Agreement is amended and restated in its entirety as follows: 
 The Borrower hereby unconditionally promises
to pay to the Administrative Agent for the account of each Lender having any Exposure the then unpaid principal amount of each Revolving Loan on the Maturity Date and, to the extent that the Borrower shall have elected such Revolving Loan to be due
on the 364th date after such Loan is made pursuant to Section 2.03, the 364th date after such Loan is made (for the avoidance of doubt, a conversion of a Loan that is a Eurodollar Borrowing to an ABR Borrowing, and vice
versa, shall not be deemed to be a new Loan hereunder and shall not reset such 364-day period). 

(xv)    Section 2.14 of the Existing Credit Agreement is amended and restated in its entirety as follows:

 (a)     If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 

(i)    the Administrative Agent determines (which determination shall be conclusive absent manifest error)
that adequate and reasonable means do not 

  
 9 

 
exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable (including, without limitation, because the LIBO Screen Rate is not available or published on a current basis), for
such Interest Period; provided that no Benchmark Transition Event shall have occurred at such time; or 

(ii)    the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the
LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to the Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; 

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, telecopy or electronic
mail as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the
conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and any such Eurodollar Borrowing shall be repaid or converted into an ABR Borrowing on the last day of the then current Interest Period
applicable thereto and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that if the circumstances giving rise to such notice affect only one Type of Borrowings,
then the other Type of Borrowings shall be permitted. 
 (b)    Notwithstanding anything to the contrary
herein or in any other Loan Document, if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect
of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark
Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this
Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will
replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is
provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such
Benchmark Replacement from Lenders comprising the Required Lenders of each Class. 
 (c)
    Notwithstanding anything to the contrary herein or in any other Loan Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior
to the Reference Time in respect of any setting of the then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Loan Document in respect of such Benchmark
setting and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document; provided that, this clause 

  
 10 

 
(c) shall not be effective unless the Administrative Agent has delivered to the Lenders and the Borrower a Term SOFR Notice. For the avoidance of doubt, the Administrative Agent shall not be
required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may do so in its sole discretion. 
 (d)
    In connection with the implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary
herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. 

(e)     The Administrative Agent will promptly notify the Borrower and the Lenders of (i) any
occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark
Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, (iv) the removal or reinstatement of any tenor of a Benchmark pursuant to clause (f) below and (v) the commencement or conclusion of any
Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 2.14, including any
determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection,
will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this
Section 2.14. 
 (f)     Notwithstanding anything to the contrary herein or in
any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including Term SOFR or the LIBO Rate) and either (A) any tenor for such
Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such
Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for
any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently
displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark
Replacement), then the Administrative Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor. 

(g)     Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability
Period, the Borrower may revoke any request for a Eurodollar Borrowing of, conversion to or continuation of Eurodollar Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed
to have converted any such request into a request for a Borrowing of or

conversion to ABR Loans. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of ABR based upon the
then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of ABR. 

(xvi)    Section 4.02(a) of the Existing Credit Agreement is amended and restated in its entirety as
follows: 
 The representations and warranties of the Borrower set forth in this Agreement (including, without limitation,
the representations and warranties set forth in Section 3.03 but excluding the last two sentences of Section 3.02) shall be true and correct in all material respects (or, in the case of any
representation or warranty qualified by materiality or Material Adverse Effect, in all respects) on and as of the date of such Borrowing, except to the extent that such representations and warranties specifically refer to an earlier date, in which
case they shall be true and correct in all material respects (or, in the case of any representation or warranty qualified by materiality or Material Adverse Effect, in all respects) as of such earlier date. 

(xvii)    Section 5.06 of the Existing Credit Agreement is amended to delete the phrase “(other than
the payment of any Restricted Payments)” now appearing therein. 
 (xviii)    Section 8.02(b) of the
Existing Credit Agreement is amended to delete the phrase “Section 2.14(b) and (c)” now appearing therein and to substitute “Section 2.14(b), (c) and (d)”
therefor. 
 (xix)    Schedule 2.01 to the Credit Agreement (Commitments) is hereby amended in its
entirety to be in the form of the Schedule 2.01 (Commitments) attached as Exhibit A hereto (the “Amended Commitments Schedule”). 

(b)    By its execution below, each Lender identified on the signature pages hereto as an “Increase Lender”
agrees, effective as of the Effective Date and subject to the satisfaction of the conditions precedent set forth in Section 1.3 below, to have its existing Commitment increased by an amount necessary to reflect the
Commitment set forth for such Lender on the Amended Commitments Schedule. The terms applicable to such increased Commitments (and the related Exposure) are set forth in the Credit Agreement. In connection with the Commitment Increase effected
hereby, the Administrative Agent shall make adjustments among the Lenders with respect to the Revolving Loans, if any, then outstanding and amounts of principal, interest, commitment fees and other amounts paid or payable with respect thereto as
shall be necessary, in the opinion of the Administrative Agent, in order to cause each Lender’s portion of the outstanding Revolving Loans and related Exposure to equal its Applicable Percentage thereof, after giving effect to this Amendment;
provided, that, in respect of any Eurodollar Loan outstanding on the Effective Date, the Company hereby agrees to compensate each Lender for all losses, expenses and liabilities incurred by such Lender in connection with the sale and
assignment of such Eurodollar Loan necessitated by such adjustments on the terms and in the manner as set forth in Section 2.16 of the Credit Agreement. 

(c)    Subject to the terms and conditions set forth herein, (i) Wells Fargo agrees to extend a new Commitment on the
Amendment No. 1 Effective Date in an amount equal to $25,500,000, and (ii) Citizens agrees to extend a new Commitment on the Amendment No. 1 Effective Date in an amount equal to $19,000,000. As of the Amendment No. 1 Effective
Date, each New Lender agrees to be bound by the provisions of the Credit Agreement and agrees that it shall be a Lender for all purposes of the Credit Agreement to the same extent as if originally a party thereto, with an aggregate Commitment in
such amount 

  
 12 

 
set forth on Schedule 2.01 to the Credit Agreement. In addition, each New Lender (i) represents and warrants that it is legally authorized to enter into this Amendment and the Credit
Agreement, (ii) confirms that it has received a copy of the Existing Credit Agreement, together with copies of the most recent financial statements delivered pursuant to Section 5.01 thereof, as applicable, and has reviewed such other
documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Amendment, (iii) agrees that it will, independently and without reliance upon the Administrative Agent, any Arranger or any
other Lender and 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 the Credit Agreement, any other Loan Document, or any other instrument
or document furnished pursuant hereto or thereto, (iv) appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Credit Agreement, the other Loan Documents
and any other instrument or document furnished pursuant hereto or thereto as are delegated to the Administrative Agent by the terms thereof, together with such powers as are incidental thereto, (v) agrees that it will be bound by the provisions
of the Credit Agreement and will perform in accordance with its terms all the obligations which by the terms of the Credit Agreement are required to be performed by it as a Lender and (vi) represents and warrants that it is not an Ineligible
Institution. On the Amendment No. 1 Effective Date, each New Lender shall make available to the Administrative Agent such amounts in immediately available funds as the Administrative Agent shall determine, for the benefit of the other Lenders,
as being required in order to cause, after giving effect to the Commitment Increase and the use of such amounts to make payments to such other Lenders, each Lender’s portion of all outstanding Revolving Loans to equal such Lender’s
Applicable Percentage of such outstanding Revolving Loans, and the Administrative Agent shall make such other adjustments among the Lenders with respect to the Revolving Loans then outstanding and amounts of principal, interest, commitment fees and
other amounts paid or payable with respect thereto as shall be necessary, in the opinion of the Administrative Agent, in order to effect such reallocation. 

Section 1.2    Representations and Warranties. The Company represents and warrants to the Administrative Agent
and each Lender that: 
 (a)    the representations and warranties of the Company set forth in the Credit Agreement
(including, without limitation, the representations and warranties set forth in Section 3.03 and the last two sentences of Section 3.02) are true and correct in all material respects (or, in the
case of any representation or warranty qualified by materiality or Material Adverse Effect, in all respects) on and as of the Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in
which case they shall be true and correct in all material respects (or, in the case of any representation or warranty qualified by materiality or Material Adverse Effect, in all respects) as of such earlier date; 

(b)    at the time of and immediately after giving effect to this Amendment and the transactions contemplated hereby, no

Amendment and the Credit Agreement have been duly authorized by all necessary corporate action on its part (including, without limitation, any required shareholder approvals); and (iii) this Amendment has been duly and validly executed and
delivered by the Company and this Amendment and the Credit Agreement constitutes the Company’s legal, valid and binding obligation, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by

enforceability is considered in a proceeding in equity or at law); and 

  
 13 

 (d)    none of the execution and delivery by the Company of this
Amendment and the performance by the Company of this Amendment, the Credit Agreement and the transactions contemplated hereby and thereby (a) will conflict with or result in a breach of, or require any consent under (i) the articles of

any of them or any of their property is subject, or constitute a default under any such agreement or instrument, which conflict, breach or consent requirement referred to in this clause (ii), including any failure to obtain any such consent,

EXECUTION VERSION 

AMENDMENT NO. 1 TO FOURTH AMENDED AND RESTATED CREDIT AGREEMENT 

This AMENDMENT NO. 1 TO FOURTH AMENDED AND RESTATED CREDIT AGREEMENT (this “Amendment”), dated as of February 3, 2021,
is entered into by and among National Fuel Gas Company (the “Company”), the lenders listed on the signature pages hereto and JPMorgan Chase Bank, N.A., as Administrative Agent (in such capacity, the “Administrative
Agent”), in respect of the Credit Agreement described below. 
 W I T N E S S E T H: 

WHEREAS, the Company is a party to that certain Fourth Amended and Restated Credit Agreement, dated as of October 25, 2018 (as the same
may be amended, restated, supplemented or otherwise modified prior to the date hereof, the “Existing Credit Agreement”, and as amended by this Amendment, the “Credit Agreement”; capitalized terms used and not
otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement), among the Company, the lenders from time to time party thereto (the “Lenders”) and the Administrative Agent; 

WHEREAS, the parties hereto have agreed to amend the Existing Credit Agreement on the terms and conditions set forth herein; 

NOW THEREFORE, in consideration of the premises herein contained, and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties hereto hereby agree as follows: 
 Section 1.1    Amendments to the Existing
Credit Agreement. 
 (a)    Effective as of the date first set forth above and subject to the conditions precedent
set forth in Section 1.3 below, the parties hereto agree that the Existing Credit Agreement is hereby amended as follows: 

(i)    Section 1.01 of the Existing Credit Agreement is amended to add the following definitions thereto in
alphabetical order: 
 “Available Tenor” means, as of any date of determination and with respect to the
then-current Benchmark, as applicable, any tenor for such Benchmark or payment period for interest calculated with reference to such Benchmark, as applicable, that is or may be used for determining the length of an Interest Period pursuant to this
Agreement as of such date and not including, for the avoidance of doubt, any tenor for such Benchmark that is then-removed from the definition of “Interest Period” pursuant to clause (f) of Section 2.14. 

“Benchmark” means, initially, the LIBO Rate; provided that if a Benchmark Transition Event, a Term SOFR
Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred with respect to the LIBO Rate or the then-current Benchmark, then “Benchmark”
means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant to clause (b) or clause (c) of Section 2.14. 

“Benchmark Replacement” means, for any Available Tenor, the first alternative set forth in the order below
that can be determined by the Administrative Agent for the applicable Benchmark Replacement Date: 

  

 (1)     the sum of: (a) Term SOFR and (b) the
related Benchmark Replacement Adjustment; 
 (2)     the sum of: (a) Daily Simple SOFR and
(b) the related Benchmark Replacement Adjustment; 
 (3)     the sum of: (a) the alternate
benchmark rate that has been selected by the Administrative Agent and the Borrower as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a
replacement benchmark rate or the mechanism for determining such a rate by the Relevant Governmental Body or (ii) any evolving or then-prevailing market convention for determining a benchmark rate as a replacement for the then-current Benchmark
for dollar-denominated syndicated credit facilities at such time and (b) the related Benchmark Replacement Adjustment; 

provided that, in the case of clause (1), such Unadjusted Benchmark Replacement is displayed on a screen or other
information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion; provided further that, notwithstanding anything to the contrary in this Agreement or in any other Loan
Document, upon the occurrence of a Term SOFR Transition Event, and the delivery of a Term SOFR Notice, on the applicable Benchmark Replacement Date the “Benchmark Replacement” shall revert to and shall be deemed to be the sum of
(a) Term SOFR and (b) the related Benchmark Replacement Adjustment, as set forth in clause (1) of this definition (subject to the first proviso above). 

If the Benchmark Replacement as determined pursuant to clause (1), (2) or (3) above would be less than the Floor, the
Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents. 

“Benchmark Replacement Adjustment” means, with respect to any replacement of the then-current Benchmark with
an Unadjusted Benchmark Replacement for any applicable Interest Period and Available Tenor for any setting of such Unadjusted Benchmark Replacement: 

(1)    for purposes of clauses (1) and (2) of the definition of “Benchmark Replacement,” the
first alternative set forth in the order below that can be determined by the Administrative Agent: 
 (a) the spread
adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that has been selected or
recommended by the Relevant Governmental Body for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for the applicable Corresponding Tenor; 

(b) the spread adjustment (which may be a positive or negative value or zero) as of the Reference Time such Benchmark
Replacement is first set for such Interest Period that would apply to the fallback rate for a derivative transaction referencing the ISDA Definitions to be effective upon an index cessation event with respect to such Benchmark for the applicable
Corresponding Tenor; and 

  
 2 

 (2)     for purposes of clause (3) of the
definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Administrative Agent and the
Borrower for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with
the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or (ii) any evolving or then-prevailing market convention for determining a spread adjustment, or method for
calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for dollar-denominated syndicated credit facilities; 

provided that, in the case of clause (1) above, such adjustment is displayed on a screen or other information
service that publishes such Benchmark Replacement Adjustment from time to time as selected by the Administrative Agent in its reasonable discretion. 

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical,
administrative or operational changes (including changes to the definition of “Alternate Base Rate,” the definition of “Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and
making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the
Administrative Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Administrative Agent in a manner substantially consistent with market practice
(or, if the Administrative Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Administrative Agent determines that no market practice for the administration of such Benchmark Replacement
exists, in such other manner of administration as the Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents). 

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the
then-current Benchmark: 
 (1)     in the case of clause (1) or (2) of the definition of
“Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of such Benchmark (or the published component used in
the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof); 

(2)     in the case of clause (3) of the definition of “Benchmark Transition Event,” the
date of the public statement or publication of information referenced therein; or 
 (3)     in the case
of a Term SOFR Transition Event, the date that is thirty (30) days after the date a Term SOFR Notice is provided to the Lenders and the Borrower pursuant to Section 2.14(c); or 

(4)     in the case of an Early Opt-in Election, the sixth (6th)
Business Day after 

  
 3 

 
the date notice of such Early Opt-in Election is provided to the Lenders, so long as the Administrative Agent has not received, by 5:00 p.m.
(New York City time) on the fifth (5th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, written notice of objection to such Early Opt-in Election from Lenders comprising the Required Lenders. 
 For the avoidance of
doubt, (i) if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the
Reference Time for such determination and (ii) the “Benchmark Replacement Date” will be deemed to have occurred in the case of clause (1) or (2) with respect to any Benchmark upon the occurrence of the applicable event or events
set forth therein with respect to all then-current Available Tenors of such Benchmark (or the published component used in the calculation thereof). 

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the
then-current Benchmark:

the administrator of such Benchmark (or the published component used in the calculation thereof) announcing that such administrator has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof), permanently

“Early Opt-in Election” means, if the then-current Benchmark is the
LIBO Rate, the occurrence of: 
 (1)    a notification by the Administrative Agent to (or the request by

SOFR-based rate (including SOFR, a term SOFR or any other rate based upon SOFR) as a benchmark rate (and such syndicated credit facilities are identified in such notice and are publicly available for review), and 

(2)    the joint election by the Administrative Agent and the Borrower to trigger a fallback from the LIBO
Rate and the provision by the Administrative Agent of written notice of such election to the Lenders.

forward-looking term rate based on SOFR that has been selected or recommended by the Relevant Governmental Body.

occurrence of a Term SOFR Transition Event.

 (ii)    Section 1.05 of the Existing Credit Agreement is amended and
restated in its entirety as follows: 
 Interest Rates; LIBOR Notification. The interest rate on Eurodollar Loans is
determined by reference to the LIBO Rate, which is derived from the London interbank offered rate.    The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term
borrowings from each other in the London interbank market. In July 2017, the U.K. Financial Conduct Authority announced that, after the end of 2021, it would no longer persuade or compel contributing banks to make rate submissions to the ICE
Benchmark Administration (together with any successor to the ICE Benchmark Administrator, the “IBA”) for purposes of the IBA setting the London interbank offered rate. As a result, it is possible that commencing in 2022, the London
interbank offered rate may no longer be available or may no longer be deemed an appropriate reference rate upon which to determine the interest rate on Eurodollar Loans. In light of this eventuality, public and private sector industry initiatives
are currently underway to identify new or alternative reference rates to be used in place of the London interbank offered rate. Upon the occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-In Election, Section 2.14(b) and (c) provide the mechanism for determining an alternative rate of interest. The Administrative Agent will

  
 6 

 
promptly notify the Borrower, pursuant to Section 2.14(e), of any change to the reference rate upon which the interest rate on Eurodollar Loans is based. However, the
Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, the administration, submission or any other matter related to the London interbank offered rate or other rates in the
definition of “LIBO Rate” or with respect to any alternative or successor rate thereto, or replacement rate thereof (including, without limitation, (i) any such alternative, successor or replacement rate implemented pursuant to
Section 2.14(b) or (c), whether upon the occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, and (ii) the implementation
of any Benchmark Replacement Conforming Changes pursuant to Section 2.14(d)), including without limitation, whether the composition or characteristics of any such alternative, successor or replacement reference rate will be
similar to, or produce the same value or economic equivalence of, the LIBO Rate or have the same volume or liquidity as did the London interbank offered rate prior to its discontinuance or unavailability. 

(iii)    Section 2.14 of the Existing Credit Agreement is amended and restated in its entirety as follows:

 (a)     If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 

(i)    the Administrative Agent determines (which determination shall be conclusive absent manifest error)
that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable (including, without limitation, because the LIBO Screen Rate is not available or published on a current basis), for such Interest
Period; provided that no Benchmark Transition Event shall have occurred at such time; or 

(ii)    the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the
LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to the Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; 

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, telecopy or electronic
mail as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the
conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and any such Eurodollar Borrowing shall be repaid or converted into an ABR Borrowing on the last day of the then current Interest Period
applicable thereto and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that if the circumstances giving rise to such notice affect only one Type of Borrowings,
then the other Type of Borrowings shall be permitted. 
 (b)    Notwithstanding anything to the contrary
herein or in any other Loan Document, if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect
of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement 

  
 7 

 
is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such
Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan
Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for
all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without
any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from
Lenders comprising the Required Lenders of each Class. 
 (c)     Notwithstanding anything to the
contrary herein or in any other Loan Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the
then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings, without any
amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document; provided that, this clause (c) shall not be effective unless the Administrative Agent has delivered to the Lenders and the
Borrower a Term SOFR Notice. For the avoidance of doubt, the Administrative Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may do so in its sole discretion. 

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

(e)     The Administrative Agent will promptly notify the Borrower and the Lenders of (i) any
occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark
Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, (iv) the removal or reinstatement of any tenor of a Benchmark pursuant to clause (f) below and (v) the commencement or conclusion of any
Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 2.14, including any
determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection,
will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this
Section 2.14. 

  
 8 

 (f)     Notwithstanding anything to the contrary herein
or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then-current Benchmark is a term rate (including Term SOFR or the LIBO Rate) and either (A) any tenor for such
Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such
Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for
any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently
displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark
Replacement), then the Administrative Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor. 

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

(iv)    Section 8.02(b) of the Existing Credit Agreement is amended to delete the phrase
“Section 2.14(b)” now appearing therein and to substitute “Section 2.14(b), (c) and (d)” therefor. 

Section 1.2    Representations and Warranties. The Company represents and warrants to the Administrative Agent
and each Lender that: 
 (a)    the representations and warranties of the Company set forth in the Credit Agreement
(including, without limitation, the representations and warranties set forth in Section 3.03 and the last two sentences of Section 3.02) are true and correct in all material respects (or, in the
case of any representation or warranty qualified by materiality or Material Adverse Effect, in all respects) on and as of the Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in
which case they shall be true and correct in all material respects (or, in the case of any representation or warranty qualified by materiality or Material Adverse Effect, in all respects) as of such earlier date; 

(b)    at the time of and immediately after giving effect to this Amendment and the transactions contemplated hereby, no
Default shall have occurred and be continuing; 
 (c)    (i) the Company has all necessary corporate power, authority
and legal right to execute and deliver this Amendment, and to perform its obligations under this Amendment and the Credit Agreement; (ii) the execution and delivery by the Company of this Amendment, and the performance by the Company of this
Amendment and the Credit Agreement have been duly authorized by all necessary corporate action on its part (including, without limitation, any required shareholder approvals); and (iii) this Amendment

  
 9 

 
has been duly and validly executed and delivered by the Company and this Amendment and the Credit Agreement constitutes the Company’s legal, valid and binding obligation, enforceable against
the Company in accordance with its terms, except as such enforceability may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability affecting the enforcement of creditors’ rights and
(B) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); and 

(d)    none of the execution and delivery by the Company of this Amendment and the performance by the Company of this
Amendment, the Credit Agreement and the transactions contemplated hereby and thereby (a) will conflict with or result in a breach of, or require any consent under (i) the articles of incorporation or
by-laws of the Company, or (ii) any applicable law or regulation, or, to the best knowledge of the Company, any order, writ, injunction or decree of any court or governmental or regulatory authority,
agency, instrumentality or political subdivision thereof, or any material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which any of them or any of their property is bound or to which any of them or any of
their property is subject, or constitute a default under any such agreement or instrument, which conflict, breach or consent requirement referred to in this clause (ii), including any failure to obtain any such consent, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect. 
 Section 1.3    Conditions

Date”):
