(d)    in the case of an Early Opt-in Election, the sixth (6th) 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 Majority Lenders.

For the avoidance of doubt, a “Benchmark Transition Event” will be deemed to have occurred with respect to any Benchmark if a public statement or publication of information set forth above has occurred with respect to each then-current Available Tenor of such Benchmark (or the published component used in the calculation thereof).

2.2    Amendment to Section 1.08. Section 1.08 is hereby amended and restated in its entirety to read as follows:

Section 1.08    Rates. The interest rate on Eurodollar Loans and ABR Loans (when determined by reference to clause (c) of the definition of Alternate Base Rate) may be 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. On March 5, 2021, ICE Benchmark Administration (“IBA”), the administrator of the London interbank offered rate, and the Financial Conduct Authority (the “FCA”), the regulatory supervisor of IBA, announced in public statements (the “Announcements”) that the final publication or representativeness date for the London interbank offered rate for Dollars for: (a) 1-week and 2-month tenor settings will be December 31, 2021 and (b) overnight, 1-month, 3-month, 6-month and 12-month tenor settings will be June 30, 2023. No successor

administrator for IBA was identified in such Announcements. As a result, it is possible that commencing immediately after such dates, the London interbank offered rate for such tenors may no longer be available or may no longer be deemed a representative reference rate upon which to determine the interest rate on Eurodollar Loans or ABR Loans (when determined by reference to clause (c) of the definition of Alternate Base Rate). There is no assurance that the dates set forth in the Announcements will not change or that IBA or the FCA will not take further action that could impact the availability, composition or characteristics of any London interbank offered rate. Public and private sector industry initiatives have been and continue, as of the date hereof, to be underway to implement new or alternative reference rates to be used in place of the London interbank offered rate. In the event that the London interbank offered rate or any other then-current Benchmark is no longer available or in certain other circumstances set forth in Section 3.03(b), such Section 3.03(b) provides a mechanism for determining an alternative rate of interest. The Administrative Agent will notify the Borrower, pursuant to Section 3.03(b), of any change to the reference rate upon which the interest rate on Eurodollar Loans and ABR Loans (when determined by reference to clause (c) of the definition of Alternate Base Rate) is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, (i) the continuation of, administration of, submission of, calculation of 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, successor or replacement rate thereto (including any then-current Benchmark or any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement), as it may or may not be adjusted pursuant to Section 3.03(b), will be similar to, or produce the same value or economic equivalence of, the LIBO Rate or any other Benchmark, or have the same volume or liquidity as did the London interbank offered rate or any other Benchmark prior to its discontinuance or unavailability, or (ii) the effect, implementation or composition of any Benchmark Replacement Conforming Changes. The Administrative Agent and its Affiliates or other related entities may engage in transactions that affect the calculation of a Benchmark, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto and such transactions may be adverse to the Borrower. The Administrative Agent may select information sources or services in its reasonable discretion to ascertain any Benchmark, any component definition thereof or rates referenced in the definition thereof, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender or any other person or entity for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs, losses or expenses (whether in tort, contract or otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service.

2.3    Amendment to Section 2.07(a). Section 2.07(a) is hereby amended and restated in its entirety to read as follows:

(a)    Fourth Amendment Borrowing Base. For the period from and including the Fourth Amendment Effective Date to but excluding the next Redetermination Date, the amount of the Borrowing Base shall be $650,000,000. For purposes of this Agreement, the determination of the Borrowing Base on the Fourth Amendment Effective Date provided for in the immediately preceding sentence shall constitute the October 2021 Redetermination. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments in between Scheduled Redeterminations from time to time pursuant to Section 2.07(e), Section 2.07(f), Section 2.07(h) or Section 8.12(c).

2.4    Amendment to Section 3.03(b). Section 3.03(b) is hereby amended and restated in its entirety to read as follows:

(b)    Benchmark Replacement Setting.

(i)    Benchmark Replacement.

(A)    Notwithstanding anything to the contrary herein or in any other Loan Document (and any Swap Agreement shall be deemed not to be a “Loan Document” for purposes of this Section 3.03(b)) 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 (a)(1) or (a)(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 (a)(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 Majority Lenders. If an Unadjusted Benchmark Replacement is Daily Simple SOFR, all interest payments will be payable on a quarterly basis.

(B)    Notwithstanding anything to the contrary herein or in any other Loan Document, 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 (B) shall not be effective unless the Administrative Agent has delivered to the Lenders and the Borrower a Term SOFR Notice. For the avoidance of doubt, the Administrative Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may elect or not elect to do so in its sole discretion.

(ii)    Benchmark Replacement Conforming Changes. 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.

(iii)    Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (A) any occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes, (D) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 3.03(b)(iv) below and (E) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 3.03(b), 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 3.03(b).

(iv)    Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (A) if the then-current Benchmark is a term rate (including Term SOFR or USD LIBOR) and either (1) any tenor for such Benchmark is not displayed on a screen or other

information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (2) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (B) if a tenor that was removed pursuant to clause (A) above either (1) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (2) is not, or is no longer, subject to an announcement that it is or will 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.

(v)    Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any request for a 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 the Alternate Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Alternate Base Rate.

(vi)    London Interbank Offered Rate Benchmark Transition Event. On March 5, 2021, the IBA, the administrator of the London interbank offered rate, and the FCA, the regulatory supervisor of the IBA, made the Announcements that the final publication or representativeness date for Dollars for (I) 1-week and 2-month London interbank offered rate tenor settings will be December 31, 2021 and (II) overnight, 1-month, 3-month, 6-month and 12-month London interbank offered rate tenor settings will be June 30, 2023. No successor administrator for the IBA was identified in such Announcements. The parties hereto agree and acknowledge that the Announcements resulted in the occurrence of a Benchmark Transition Event with respect to the London interbank offered rate pursuant to the terms of this Agreement and that any obligation of the Administrative Agent to notify any parties of such Benchmark Transition Event pursuant to clause (iii) of this Section 3.03(b) shall be deemed satisfied.

Section 11.13    Erroneous Payments.

(a)    Each Lender, the Issuing Bank, each other Secured Party and any other party hereto hereby severally agrees that if (i) the Administrative Agent notifies (which such notice shall be conclusive absent manifest error) such Lender, the Issuing Bank or any other Secured Party or any other Person that has received funds from the Administrative Agent or any of its Affiliates, either for its own account or on behalf of a Lender, the Issuing Bank or other Secured Party (each such recipient, a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion that any funds received by such Payment Recipient were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Payment Recipient) or (ii) any Payment Recipient receives any payment from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, as applicable, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, as applicable, or (z) that such Payment Recipient otherwise becomes aware was transmitted or received in error or by mistake (in whole or in part) then, in each case, an error in payment shall be presumed to have been made (any such amounts specified in clauses (i) or (ii) of this Section 11.13(a), whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise; individually and collectively, an “Erroneous Payment”), then, in each case, such Payment Recipient is deemed to have knowledge of such error at the time of its receipt of such Erroneous Payment; provided that nothing in this Section 11.13 shall require the Administrative Agent to provide any of the notices specified in clauses (i) or (ii) above. Each Payment Recipient agrees that it shall not assert any right or claim to any Erroneous Payment, and hereby waives any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payments, including without limitation waiver of any defense based on “discharge for value” or any similar doctrine.

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

(c)    In the case of either clause (a)(i) or (a)(ii) above, such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and upon demand from the Administrative Agent such Payment Recipient shall (or, shall cause any Person who received any portion of an Erroneous Payment on its behalf to), promptly, but in all events no later than one Business Day thereafter, return to the Administrative Agent the amount of

any such Erroneous Payment (or portion thereof) as to which such a demand was made in same day funds and in the currency so received, together with interest thereon in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation from time to time in effect.

(d)    In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with immediately preceding clause (c), from any Lender that is a Payment Recipient or an Affiliate of a Payment Recipient (such unrecovered amount as to such Lender, an “Erroneous Payment Return Deficiency”), then at the sole discretion of the Administrative Agent and upon the Administrative Agent’s written notice to such Lender (i) such Lender shall be deemed to have made a cashless assignment of the full face amount of the portion of its Loans (but not its Commitments) to the Administrative Agent or, at the option of the Administrative Agent, the Administrative Agent’s applicable lending affiliate in an amount that is equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Loans (but not Commitments), the “Erroneous Payment Deficiency Assignment”) plus any accrued and unpaid interest on such assigned amount, without further consent or approval of any party hereto and without any payment by the Administrative Agent or its applicable lending affiliate as the assignee of such Erroneous Payment Deficiency Assignment. Without limitation of its rights hereunder, the Administrative Agent may cancel any Erroneous Payment Deficiency Assignment at any time by written notice to the applicable assigning Lender and upon such revocation all of the Loans assigned pursuant to such Erroneous Payment Deficiency Assignment shall be reassigned to such Lender without any requirement for payment or other consideration. The parties hereto acknowledge and agree that (1) any assignment contemplated in this clause (d) shall be made without any requirement for any payment or other consideration paid by the applicable assignee or received by the assignor, (2) the provisions of this clause (d) shall govern in the event of any conflict with the terms and conditions of Section 12.04 and (3) the Administrative Agent may reflect such assignments in the Register without further consent or action by any other Person.

(e)    Each party hereto hereby agrees that (x) in the event an Erroneous Payment (or portion thereof) is not recovered from any Payment Recipient that has received such Erroneous Payment (or portion thereof) for any reason, the Administrative Agent (1) shall be subrogated to all the rights of such Payment Recipient with respect to such amount and (2) is authorized to set off, net and apply any and all amounts at any time owing to such Payment Recipient under any Loan Document, or otherwise payable or distributable by the Administrative

Agent to such Payment Recipient from any source, against any amount due to the Administrative Agent under this Section 11.13 or under the indemnification provisions of this Agreement, (y) the receipt of an Erroneous Payment by a Payment Recipient shall not for the purpose of this Agreement be treated as a payment, prepayment, repayment, discharge or other satisfaction of any Obligations owed by the Borrower or any other Loan Party, except, in each case, to the extent such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrower or any other Loan Party for the purpose of making a payment on the Obligations and (z) to the extent that an Erroneous Payment was in any way or at any time credited as payment or satisfaction of any of the Obligations, the Obligations or any part thereof that was so credited, and all rights of the Payment Recipient, as the case may be, shall be reinstated and continue in full force and effect as if such payment or satisfaction had never been received, except to the extent such Erroneous Payment was, and solely with respect to the amount of such Erroneous Payment that was, comprised of funds received by the Administrative Agent from the Borrower or any other Loan Party for the purpose of making a payment on the Obligations.

(f)    Each party’s obligations under this Section 11.13 shall survive the resignation or replacement of the Administrative Agent or any transfer of right or obligations by, or the replacement of, a Lender, the termination of the Commitments or the repayment, satisfaction or discharge of all Obligations (or any portion thereof) under any Loan Document.

(g)    Nothing in this Section 11.13 will constitute a waiver or release of any claim of any party hereunder arising from any Payment Recipient’s receipt of an Erroneous Payment.

2.6    Amendment to Section 12.06. Section 12.06 is hereby amended by adding a new subsection (d) to read as follows:

The words “execute,” “execution,” “signed,” “signature,” “delivery” and words of like import in or related to this Agreement, any other Loan Document or any document, amendment, approval, consent, waiver, modification, information, notice, certificate, report, statement, disclosure, or authorization to be signed or delivered in connection with this Agreement or any other Loan Document or the transactions contemplated hereby shall be deemed to include Electronic Signatures or execution in the form of an Electronic Record, and contract formations on electronic platforms approved by the Administrative Agent, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any Applicable Law, including the Federal Electronic Signatures in Global and National Commerce

Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.  Each party hereto agrees that any Electronic Signature or execution in the form of an Electronic Record shall be valid and binding on itself and each of the other parties hereto to the same extent as a manual, original signature.  For the avoidance of doubt, the authorization under this paragraph may include, without limitation, use or acceptance by the parties of a manually signed paper which has been converted into electronic form (such as scanned into PDF format), or an electronically signed paper converted into another format, for transmission, delivery and/or retention.  Notwithstanding anything contained herein to the contrary, the Administrative Agent is under no obligation to accept an Electronic Signature in any form or in any format unless expressly agreed to by the Administrative Agent pursuant to procedures approved by it; provided that, without limiting the foregoing, (a) to the extent the Administrative Agent has agreed to accept such Electronic Signature from any party hereto, the Administrative Agent and the other parties hereto shall be entitled to rely on any such Electronic Signature purportedly given by or on behalf of the executing party without further verification and (b) upon the request of the Administrative Agent or any Lender, any Electronic Signature shall be promptly followed by an original manually executed counterpart thereof.  Without limiting the generality of the foregoing, each party hereto hereby (i) agrees that, for all purposes, including without limitation, in connection with any workout, restructuring, enforcement of remedies, bankruptcy proceedings or litigation among the Administrative Agent, the Lenders and any of the Loan Parties, electronic images of this Agreement or any other Loan Document (in each case, including with respect to any signature pages thereto)  shall have the same legal effect, validity and enforceability as any paper original, and (ii) waives any argument, defense or right to contest the validity or enforceability of the Loan Documents based solely on the lack of paper original copies of any Loan Documents, including with respect to any signature pages thereto.

3.2    On the Fourth Amendment Effective Date, immediately prior to giving effect to the amendments in Section 2 of this Fourth Amendment, each Existing Lender has, in consultation with the Borrower, agreed to, and, for an agreed consideration, does hereby reallocate its Maximum Credit Amount, Commitment and Loans (and participations in Letters of Credit and LC Disbursements) among other things, to allow the Exiting Lender to sell and assign all of its Maximum Credit Amount, Commitment and Loans (and participations in Letters of Credit and LC Disbursements) and to allow the New Lender to become a party to the Credit Agreement as a Lender by acquiring an interest in the Aggregate Maximum Credit Amount and the total Commitments (the “Reallocation”). On the Fourth Amendment Effective Date, and after giving effect to the Reallocation: (a) the Maximum Credit Amount and Applicable Percentage of each Lender (including the New Lender) shall be as set forth on Annex I attached to this Fourth Amendment, which Annex I supersedes and replaces Annex I to the Credit Agreement (and Annex I to the Credit Agreement is hereby amended and restated in its entirety to read as set forth on Annex I attached hereto) (and for the avoidance of doubt, the Commitment of the Exiting Lender shall be $0); (b) the Exiting Lender shall cease to be a “Lender” for all purposes under the Credit Agreement and the other Loan Documents but shall continue to be entitled to the benefits of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 of the Credit Agreement; and (c) the New Lender shall become a party to the Credit Agreement, as amended by this Fourth Amendment, as a “Lender” and have all of the rights and obligations of a Lender under the Credit Agreement, as amended by this Fourth Amendment, and the other Loan Documents.

With respect to the Reallocation, each Existing Lender shall be deemed to have sold and assigned its Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit, and the New Lender and each Continuing Lender shall be deemed to have acquired the Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit allocated to it from each Existing Lender, pursuant to the terms and conditions of the Assignment and Assumption attached as Exhibit G to the Credit Agreement (the “Assignment Agreement”), as if each Existing Lender and the New Lender had executed such Assignment Agreement with respect to the Reallocation, pursuant to which, (i) the New Lender and each Continuing Lender shall be an “Assignee”, (ii) each Existing Lender shall be an “Assignor” and (iii) the term “Effective Date” shall be the Fourth Amendment Effective Date as defined herein.
