Any change in the Alternate Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate or Adjusted Term SOFR shall be effective from and including the effective date of such change in the Prime Rate, the Federal Funds Effective Rate or Adjusted Term SOFR, respectively. Notwithstanding the foregoing, in no event shall the Alternate Base Rate be less than 1.00%.

“Applicable Margin” means, for any day, with respect to any ABR Loan or SOFR Loan, or with respect to the Commitment Fee Rate, as the case may be, the rate per annum set forth in the Borrowing Base Utilization Grid below based upon the Borrowing Base Utilization Percentage then in effect:


Borrowing Base Utilization Grid
	<25%	≥25%, but <50%	≥50%, but <75%	≥75%, but <90%	≥90%
ABR Loans	1.50%	1.75%	2.00%	2.25%	2.50%
SOFR Loans	2.50%	2.75%	3.00%	3.25%	3.50%

Notwithstanding the foregoing, (a) if the Consolidated Leverage Ratio for the Reference Period ending on the last day of any fiscal quarter or fiscal year, as applicable, is greater than 1.50 to 1.00, then the Applicable Margin set forth in the above grid with respect to ABR Loans and SOFR Loans (but, for purposes of clarity, not the Commitment Fee Rate) will, in each case, (and, for the avoidance of doubt, after giving effect to any increases to the Applicable Margin set forth in the above grid pursuant to clause (b) and/or clause (c) below) increase by 0.25% during the period from and including the first day immediately following the date the financial statements and the related compliance certificate are delivered pursuant to Section 8.01(a) or Section 8.01(b), as applicable, and Section 8.01(c) for such fiscal quarter or fiscal year, as applicable, through and including the date of delivery of the financial statements and the related compliance certificate pursuant to Section 8.01(a) or Section 8.01(b), as applicable, and Section 8.01(c) for the immediately succeeding fiscal quarter; (b) in addition to any increases to the Applicable Margin provided in clause (a) above and/or clause (c) below, if the Fifth Amendment Senior Notes Trigger Event shall not have occurred on or prior to the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, then effective as of the ▇▇▇▇▇▇▇▇ Acquisition Effective Date and at all times thereafter, the Applicable Margin set forth in the above grid with respect to ABR Loans and SOFR Loans (but, for purposes of clarity, not the Commitment Fee Rate) will, in each case, increase by 0.25%; and (c) in addition to any increases to the Applicable Margin provided in clauses (a) and/or (b) above, if the Fifth Amendment Senior Notes Trigger Event shall not have occurred on or prior to the later of April 15, 2022 and the Bighorn Acquisition Effective Date, then effective on the later of April 15, 2022 and the Bighorn Acquisition Effective Date and until the Fifth Amendment Senior Notes Trigger Event shall have occurred, the Applicable Margin set forth in the above grid with respect to ABR Loans and SOFR Loans (but, for purposes of clarity, not the Commitment Fee Rate) will, in each case, increase by 0.50%. Each change in the Applicable Margin and Commitment Fee Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change; provided, however, that if at any time the Borrower fails to deliver (i) a Reserve Report pursuant to Section 8.11(a) or (ii) the financial statements and the related compliance certificate pursuant to Section 8.01(a) or Section 8.01(b), as applicable, and Section 8.01(c), then, if so elected by the Majority Lenders, the “Applicable Margin” means the rate per annum set forth on the grid when the Borrowing Base Utilization Percentage is at its highest level.

In the event that the certified calculation of the Consolidated Leverage Ratio previously delivered pursuant to Section 8.01(c) was inaccurate (and such

inaccuracy is discovered while any Commitments or Loans are outstanding), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin for the Loans for any period (an “Applicable Period”) than the Applicable Margin applied for such Applicable Period, then, to the extent any Commitments or Loans are outstanding at such time, (i) the Borrower shall as soon as practicable deliver to the Administrative Agent the correct certified calculation of the Consolidated Leverage Ratio for such Applicable Period, (ii) the Applicable Margin shall be determined as if the level for such higher Applicable Margin were applicable for such Applicable Period, and (iii) the Borrower shall within ten (10) Business Days of written demand thereof by the Administrative Agent pay to the Administrative Agent the accrued additional interest owing as a result of such increased Applicable Margin for the Loans for such Applicable Period, which payment shall be promptly applied by the Administrative Agent in accordance with this Agreement.

“Benchmark” means, initially, the Term SOFR Reference Rate; provided that if a Benchmark Transition Event has occurred with respect to the Term SOFR Reference 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 Section 3.03(b)(i).

Replacement for any applicable Available Tenor, 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 giving due consideration to (a) 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 or (b) 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.

The Administrative Agent is hereby authorized and directed to declare the ▇▇▇▇▇▇▇▇ Acquisition BB Increase to be effective (and the ▇▇▇▇▇▇▇▇ Acquisition Effective Date shall occur) when it has received documents confirming

compliance with the conditions set forth in this Section 2.07(i) or the waiver of such condition in accordance with Section 12.02. Such declaration shall be final, conclusive and binding upon all parties to this Agreement for all purposes. For purposes of determining compliance with the conditions specified in this Section 2.07(i), each Lender shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to such Lender, unless the Administrative Agent shall have received written notice from such Lender prior to the ▇▇▇▇▇▇▇▇ Acquisition Effective Date specifying its objection thereto. Notwithstanding anything to the contrary contained herein, if the ▇▇▇▇▇▇▇▇ Acquisition Effective Date does not occur on or prior to 5:00 p.m. (Houston time) on the ▇▇▇▇▇▇▇▇ Acquisition Outside Date, then it shall be deemed that none of the conditions contained in this Section 2.07(i) shall be satisfied, and the ▇▇▇▇▇▇▇▇ Acquisition Effective Date shall not occur (and for the avoidance of doubt, this Section 2.07(i) shall be of no force or effect).

If the Bighorn Acquisition Effective Date has not occurred, on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, immediately prior to giving effect to the ▇▇▇▇▇▇▇▇ Acquisition BB Increase, each 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) (the “▇▇▇▇▇▇▇▇ Acquisition Reallocation”). On the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, and after giving effect to the ▇▇▇▇▇▇▇▇ Acquisition Reallocation, the Maximum Credit Amount and Applicable Percentage of each Lender shall be as set forth on Annex I-A (and Annex I to this Agreement is deemed to be amended and restated in its entirety on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date to read as set forth on Annex I-A attached hereto). Each of the Administrative Agent, each Lender, the Issuing Banks and the Borrower hereby consents and agrees to the ▇▇▇▇▇▇▇▇ Acquisition Reallocation, including each Lender’s assignment of its Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit to the extent necessary to effect the ▇▇▇▇▇▇▇▇ Acquisition Reallocation. With respect to the ▇▇▇▇▇▇▇▇ Acquisition Reallocation, each Lender shall be deemed to have sold and assigned its Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit, and each Lender shall be deemed to have acquired the Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit allocated to it from each Lender, pursuant to the terms and conditions of the Assignment and Assumption attached as Exhibit G hereto (the “▇▇▇▇▇▇▇▇ Assignment Agreement”), as if each Lender had executed such ▇▇▇▇▇▇▇▇ Assignment Agreement with respect to the ▇▇▇▇▇▇▇▇ Acquisition Reallocation, pursuant to which, (i) each Lender shall be an “Assignee”, (ii) each Lender shall be an “Assignor” and (iii) the term “Effective Date” shall be the ▇▇▇▇▇▇▇▇ Acquisition Effective Date. The Administrative Agent hereby waives the fee payable to the Administrative Agent pursuant to Section 12.04(b) in connection with the ▇▇▇▇▇▇▇▇ Acquisition Reallocation and the ▇▇▇▇▇▇▇▇ Assignment Agreement. The ▇▇▇▇▇▇▇▇ Acquisition Reallocation shall be without recourse to each Lender and, except as expressly provided in the ▇▇▇▇▇▇▇▇ Assignment Agreement, without representation or warranty by such Lender. On the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, the Administrative Agent shall take the actions specified in Section 12.04(b)(iv), including recording the assignments described herein in the Register, and such assignments shall be effective for all purposes of this Agreement. If on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, any SOFR Loans have been funded, then the Borrower shall be obligated to pay any breakage fees or costs that are payable pursuant to Section 5.02 in connection with the

reallocation of such outstanding SOFR Loans to effectuate the provisions of this paragraph.

Notwithstanding the foregoing or anything to the contrary contained herein, if, on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, the Borrower does not acquire at least (i) 95% of the total value of the proved Oil and Gas Properties evaluated in the ▇▇▇▇▇▇▇▇ Reserve Report and (ii) 95% of the total value of the proved developed producing Oil and Gas Properties evaluated in the ▇▇▇▇▇▇▇▇ Reserve Report, pursuant to the ▇▇▇▇▇▇▇▇ Acquisition Agreement, then the ▇▇▇▇▇▇▇▇ Acquisition Effective Date Borrowing Base, as applicable, shall be reduced, effective immediately on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date (for the avoidance of doubt, prior to the funding of any Loans or any other extensions of credit to be made on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date), by an amount equal to the Borrowing Base value attributable to the proved Oil and Gas Properties evaluated in the ▇▇▇▇▇▇▇▇ Reserve Report that were not acquired by the Borrower on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, as determined by the Administrative Agent, and confirmed by the Required Lenders, in each case, in good faith and in the Administrative Agent’s and each such Lender’s sole discretion and in a manner consistent with the Administrative Agent’s and such Lender’s normal oil and gas lending criteria as it exists on the ▇▇▇▇▇▇▇▇ Acquisition Effective Date (the adjustment contained in this paragraph, the “▇▇▇▇▇▇▇▇ Acquired Properties Borrowing Base Reduction”).

(j) Automatic Increase of Borrowing Base on Bighorn Acquisition Effective Date. If the Bighorn Acquisition has been consummated on or before July 13, 2022 (the “Bighorn Acquisition Outside Date”), then, subject to the conditions set forth in this Section 2.07(j), the Borrowing Base then in effect shall be automatically increased by an amount equal to: (x) if the ▇▇▇▇▇▇▇▇ Acquisition Effective Date has occurred prior to the Bighorn Acquisition Effective Date, $500,000,000 or (y) if the ▇▇▇▇▇▇▇▇ Acquisition Effective Date has not occurred prior to the Bighorn Acquisition Effective Date, the difference of (i) $500,000,000 (the “Bighorn Acquisition BB Base Increase Amount”) and (ii) the Bighorn Acquisition BB Adjustment Amount (the increase described in the foregoing clause (x) or (y), the “Bighorn Acquisition BB Increase”, and the Borrowing Base as increased by the Bighorn Acquisition BB Increase on the Bighorn Acquisition Effective Date (as defined below), the “Bighorn Acquisition Effective Date Borrowing Base”) without any further action by the Borrower, the Administrative Agent, the Issuing Banks or the Lenders, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders on the Business Day on which each of the following conditions has been satisfied (or waived in accordance with Section 12.02) (such date, the “Bighorn Acquisition Effective Date”):

(xi) The Administrative Agent shall have received such other related documents and information with respect to the Bighorn Acquisition as the Administrative Agent shall have reasonably requested.

The Administrative Agent is hereby authorized and directed to declare the Bighorn Acquisition BB Increase to be effective (and the Bighorn Acquisition Effective Date shall occur) when it has received documents confirming compliance with the conditions set forth in this Section 2.07(j) or the waiver of such condition in accordance with Section 12.02. Such declaration shall be final, conclusive and binding upon all parties to this Agreement for all purposes. For purposes of determining compliance with the conditions specified in this Section 2.07(j), each Lender shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to such Lender, unless the Administrative Agent shall have received written notice from such Lender prior to the Bighorn Acquisition Effective Date specifying its objection thereto. Notwithstanding anything to the contrary contained herein, if the Bighorn Acquisition Effective Date does not occur on or prior to 5:00 p.m. (Houston time) on the Bighorn Acquisition Outside Date, then it shall be deemed that none of the conditions contained in this Section 2.07(j) shall be satisfied, and the Bighorn Acquisition Effective Date shall not occur (and for the avoidance of doubt, this Section 2.07(j) shall be of no force or effect).

On the Bighorn Acquisition Effective Date, immediately prior to giving effect to the Bighorn Acquisition BB Increase, each 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) (the “Bighorn Acquisition Reallocation”). On the Bighorn Acquisition Effective Date, and after giving effect to the Bighorn Acquisition Reallocation, the Maximum Credit Amount and Applicable Percentage of each Lender shall be as set forth on Annex I-B (and Annex I to this Agreement is deemed to be amended and restated in its entirety on the Bighorn Acquisition Effective Date to read as set forth on Annex I-B attached hereto). Each of the Administrative Agent, each Lender, the Issuing Banks and the Borrower hereby consents and agrees to the Bighorn Acquisition Reallocation, including each Lender’s assignment of its Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit to the extent necessary to effect the Bighorn Acquisition Reallocation. With respect to the Bighorn Acquisition Reallocation, each Lender shall be deemed to have sold and assigned its Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit, and each Lender shall be deemed to have acquired the Maximum Credit Amount, Commitment, Loans and participations in Letters of Credit allocated to it from each Lender, pursuant to the terms and conditions of the Assignment and Assumption attached as Exhibit G hereto (the “Bighorn Assignment Agreement”), as if each Lender had executed such Assignment Agreement with respect to the Bighorn Acquisition Reallocation, pursuant to which, (i) each Lender shall be an “Assignee”, (ii) each Lender shall be an “Assignor” and (iii) the term “Effective Date” shall be the Bighorn Acquisition Effective Date. The Administrative Agent hereby waives the fee payable to the Administrative Agent pursuant to Section 12.04(b) in connection with the Bighorn Acquisition Reallocation and the Bighorn Assignment Agreement. The Bighorn Acquisition Reallocation shall be without recourse to each Lender and, except as expressly provided in the Bighorn Assignment Agreement, without representation or warranty by such Lender. On the Bighorn Acquisition Effective Date, the Administrative Agent shall take the actions specified in Section 12.04(b)(iv), including recording the assignments described herein in the Register, and such assignments shall be effective for all purposes of this Agreement. If on the Bighorn Acquisition Effective Date, any SOFR Loans have been funded, then the Borrower shall be obligated to pay any breakage fees or costs that are payable pursuant to Section 5.02 in connection with the reallocation of such outstanding SOFR Loans to effectuate the provisions of this paragraph.

Notwithstanding the foregoing or anything to the contrary contained herein, if, on the Bighorn Acquisition Effective Date, the Borrower does not acquire at least (i) 95% of the total value of the proved Oil and Gas Properties evaluated in the Bighorn Reserve Report and (ii) 95% of the total value of the proved developed producing Oil and Gas Properties evaluated in the Bighorn Reserve Report, pursuant to the Bighorn Acquisition Agreement, then the Bighorn Acquisition Effective Date Borrowing Base shall be reduced, effective immediately on the Bighorn Acquisition Effective Date (for the avoidance of doubt, prior to the funding of any Loans or any other extensions of credit to be made on the Bighorn Acquisition Effective Date), by an amount equal to the Borrowing Base value attributable to the proved Oil and Gas Properties evaluated in the Bighorn Acquisition Reserve Report that were not acquired by the Borrower on the Bighorn Acquisition Effective Date, as determined by the Administrative Agent, and confirmed by the Required Lenders, in each case, in good faith and in the Administrative Agent’s and each such Lender’s sole discretion and in a manner consistent with the Administrative Agent’s and such Lender’s normal oil and gas lending criteria as it exists on the Bighorn

Acquisition Effective Date (the “Bighorn Acquired Properties Borrowing Base Reduction”). The Bighorn Acquisition Effective Date Borrowing Base as reduced by the Bighorn Acquired Properties Borrowing Base Reduction shall become the new Borrowing Base immediately, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders on the Bighorn Acquisition Effective Date (for the avoidance of doubt, prior to the funding of any Loans or any other extensions of credit to be made on the Bighorn Acquisition Effective Date or such later date, as applicable) until the next redetermination or modification thereof under this Agreement. For the avoidance of doubt, the redetermination of the Borrowing Base to occur on the Bighorn Acquisition Effective Date pursuant to the Bighorn Acquired Properties Borrowing Base Reduction, shall not constitute a Scheduled Redetermination or an Interim Redetermination.

Notwithstanding the foregoing or anything to the contrary contained herein, at any time prior to February 28, 2022, if the ▇▇▇▇▇▇▇▇ Acquisition Effective Date has not occurred at such time, the Borrower may request in writing (such request, the “Adjustment Determination Notice”) to the Administrative Agent that the Required Lenders determine the amount of the reduction, if any, of the Bighorn Acquisition BB Base Increase Amount on the Bighorn Acquisition Effective Date assuming that the ▇▇▇▇▇▇▇▇ Acquisition Effective Date will not have occurred on or prior to the Bighorn Acquisition Effective Date (the amount of such reduction, the “Bighorn Acquisition BB Adjustment Amount”). If prior to March 1, 2022, the Borrower does not deliver the Adjustment Determination Notice and the ▇▇▇▇▇▇▇▇ Acquisition Effective Date has not occurred on such date, then the Borrower shall be deemed automatically to have executed and delivered to the Administrative Agent the Adjustment Determination Notice on such date. Concurrently with the delivery or the deemed delivery of the Adjustment Determination Notice, as applicable, the Borrower shall deliver an updated pro forma financial forecast giving effect to the consummation of the Bighorn Acquisition on the Bighorn Acquisition Effective Date (and excluding, for the avoidance of doubt, the ▇▇▇▇▇▇▇▇ Acquisition), which shall be in form and substance satisfactory to the Administrative Agent in its sole discretion (the “Financial Forecast”). Promptly after its receipt (or deemed receipt) of the Adjustment Determination Notice and the Financial Forecast, the Administrative Agent shall, in good faith, propose a Bighorn Acquisition BB Adjustment Amount (the “Proposed Bighorn Acquisition BB Adjustment Amount”) based upon the most recently delivered Reserve Report and the Bighorn Reserve Report only (and, for the avoidance of doubt, excluding any Oil and Gas Properties evaluated in the ▇▇▇▇▇▇▇▇ Reserve Report) and such other information (including, without limitation, (x) the Financial Forecast and (y) the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. The Required Lenders shall approve or disapprove of the Proposed Bighorn Acquisition BB Adjustment Amount in a manner substantially consistent with the procedures set forth in Section 2.07(c)(iii). After the Bighorn Acquisition BB Adjustment Amount is approved or is deemed to have been approved by the Required Lenders, the Administrative Agent shall notify the Borrower and the Lenders of the amount of the Bighorn Acquisition BB Adjustment Amount. For the avoidance of doubt, the determination of the Bighorn Acquisition BB Adjustment Amount shall not constitute a Scheduled Redetermination or an Interim Redetermination.

(k) Borrowing Base on the Fifth Amendment Acquisitions Effective Date. Notwithstanding anything to the contrary contained herein, if the Bighorn Acquisition Effective Date occurs prior to the ▇▇▇▇▇▇▇▇ Acquisition Effective Date, then the Borrowing Base in effect immediately after giving effect to the Borrowing Base increase pursuant to Section 2.07(i) on the ▇▇▇▇▇▇▇▇ Amendment Effective Date, shall be automatically redetermined to be an amount equal to $1,325,000,000 minus the ▇▇▇▇▇▇▇▇ Acquired Properties Borrowing Base Reduction, if any, minus the Bighorn Acquired Properties Borrowing Base Reduction, if any, minus the amount of all reductions to the Borrowing Base pursuant to Section 2.07(e), Section 2.07(f) and Section 8.12(c) during the period from and including the Fifth Amendment Effective Date through and including the Fifth Amendment Acquisitions Effective Date (the “Fifth Amendment Acquisitions Effective Date Borrowing Base”). The Fifth Amendment Acquisitions Effective Date Borrowing Base shall become the new Borrowing Base immediately, effective and applicable to the Borrower, the Administrative Agent, the Issuing Banks and the Lenders on the Fifth Amendment Acquisitions Effective Date (for the avoidance of doubt, prior to the funding of any Loans or any other extensions of credit to be made on the Fifth Amendment Acquisitions Effective Date) until the next redetermination or modification thereof under this Agreement. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.07(e), Section 2.07(f) or Section 8.12(c).

2.14 Amendment to Section 3.02(b). Section 3.02(b) is hereby amended and restated in its entirety to read as follows:

The Administrative Agent will promptly notify the Borrower and the Lenders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR.

2.18 Amendment to Section 3.03. Section 3.03 is hereby amended and restated in its entirety to read as follows:

Section 3.03 Alternate Rate of Interest.

(a) Unless and until a Benchmark Replacement is implemented in accordance with Section 3.03(b) below, if prior to the commencement of any Interest Period for a SOFR Borrowing:

(i) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining Adjusted Term SOFR for the applicable Interest Period with respect to a proposed SOFR Loan on or prior to the first day of such Interest Period; or

(ii) the Administrative Agent is advised by the Majority Lenders that Adjusted Term SOFR for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then, in each case, the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, facsimile or electronic communication 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 SOFR Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a SOFR Borrowing, such Borrowing shall be made, as an ABR Borrowing.

(b) Benchmark Replacement Setting.

(i) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, upon the occurrence of a Benchmark Transition Event, the Administrative Agent and the Borrower may amend this Agreement to replace the then-current Benchmark with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all affected Lenders and the Borrower so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Majority Lenders. No replacement of a Benchmark with a Benchmark Replacement pursuant to this Section 3.03(b)(i)(A) will occur prior to the applicable Benchmark Transition Start Date.

In connection with the use, administration, adoption or implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such 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) the implementation of any Benchmark Replacement and (B) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement. The Administrative Agent will

promptly notify the Borrower of the removal or reinstatement of any tenor of a Benchmark pursuant to Section 3.03(b)(iv). 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 the Term SOFR Reference Rate) 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 not or will not be representative, then the Administrative Agent may modify the definition of “Interest Period” (or any similar or analogous definition) 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 not or will not be representative for a Benchmark (including a Benchmark Replacement), then the Administrative Agent may modify the definition of “Interest Period” (or any similar or analogous definition) 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, (A) the Borrower may revoke any pending request for a borrowing of, conversion to or continuation of SOFR 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 and (B) any outstanding affected SOFR Loans will be deemed to have been converted to ABR Loans at the end of the applicable Interest Period. 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.

2.19 Amendment to Section 3.04. Section 3.04 is hereby amended by (a) replacing each instance of the word “Eurodollar” contained therein with “SOFR” and (b) replacing the phrase “three Business Days” contained therein with “three U.S. Government Securities Business Days”.

Section 5.01 Changes in Law. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any Issuing Bank;

(ii) impose on any Lender or any Issuing Bank any other condition (other than Taxes) affecting this Agreement or SOFR Loans made by such Lender or such Issuing Bank; or

(iii) subject any Lender or any Issuing Bank to any Taxes (other than (A) Indemnified Taxes and (B) Excluded Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto;

and the result of any of the foregoing shall be to increase the cost to such Lender of making, maintaining, converting or continuing any SOFR Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

2.23 Amendment to Section 5.02. Section 5.02 is hereby amended and restated in its entirety to read as follows:

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any SOFR Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any SOFR Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any SOFR Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any SOFR Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 5.05, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be conclusive absent manifest error or bad faith. Except in cases of manifest error or bad faith, the Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

2.24 Amendment to Section 5.06. Section 5.06 is hereby amended and restated in its entirety to read as follows:

Section 5.06 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain SOFR Loans either

generally or having a particular Interest Period hereunder or to determine or charge interest based upon SOFR, the Term SOFR Reference Rate, Adjusted Term SOFR or Term SOFR, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof (an “Illegality Notice”) and (i) such Lender’s obligation to make such SOFR Loans shall be suspended and (ii) if necessary to avoid such illegality, the Administrative Agent shall compute the Alternate Base Rate without reference to clause (C) of the definition of “Alternate Base Rate”, until such time as such Lender may again make and maintain such SOFR Loans. Upon receipt of an Illegality Notice, the Borrower shall, if necessary to avoid such illegality, upon demand from any Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert all SOFR Loans to ABR Loans (in each case, if necessary to avoid such illegality, the Administrative Agent shall compute the Alternate Base Rate without reference to clause (c) of the definition of “Alternate Base Rate”), on the last day of the Interest Period therefor, if all affected Lenders may lawfully continue to maintain such SOFR Loans to such day, or immediately, if any Lender may not lawfully continue to maintain such SOFR Loans to such day. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 5.02.

3.4 No Default. As of the Fifth Amendment Effective Date, no Default shall have occurred and be continuing.

The Administrative Agent is hereby authorized and directed to declare Section 2 of this Fifth Amendment to be effective (and the Fifth Amendment Effective Date shall occur) when it has received documents confirming compliance with the conditions set forth in this Section 3 or the waiver of such condition in accordance with Section 12.02 of the Credit Agreement.
