(a) Availability of Term SOFR Advances and Daily Term SOFR Advances. Notwithstanding anything to the contrary in this Agreement or any other Loan Document, but subject to Section 2.23(b), if the Agent determines (which determination shall be conclusive absent manifest error), or the Required Banks notify the Agent that the Required Banks have determined, that:

(i) for any reason in connection with any request for a Term SOFR Advance or a Daily Term SOFR Advance or a conversion or continuation thereof that the Term SOFR Base Rate for any requested Interest Period with respect to a proposed Term SOFR Advance or a Daily Term SOFR Advance does not adequately and fairly reflect the cost to such Banks of the funding such Loans, or

(ii) the interest rate applicable to Term SOFR Advances or Daily Term SOFR Advances for any requested Interest Period is not ascertainable or available (including, without limitation, because the applicable Screen (or on any successor or substitute page on such screen) is unavailable) and such inability to ascertain or unavailability is not expected to be permanent, or does not adequately and fairly reflect the cost of making or maintaining Term SOFR Advances or Daily Term SOFR Advances,

then the Agent shall suspend the availability of Term SOFR Advances and Daily Term SOFR Advances and require any affected Term SOFR Advances and Daily Term SOFR Advances to be repaid or converted to Base Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.4.

(b) Benchmark Replacement.

(i) Benchmark Transition Event; Early Opt-in Election. 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 2.23(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 (1) 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 (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 any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth Business Day after the date notice of such Benchmark Replacement is provided by the Agent to the Banks 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 Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Banks comprising the Required Banks.

(ii) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the 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 Agent will promptly notify the Borrower and the Banks of (A) the implementation of any Benchmark Replacement, and (B) the effectiveness of any Benchmark Replacement Conforming Changes. Any determination, decision or election that may be made by the Agent or, if applicable, any Bank (or group of Banks) pursuant to this Section 2.23(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 2.23(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), (i) if the then-current Benchmark is a term rate (including the Term SOFR Base Rate, Term SOFR or the Daily Term SOFR Base 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 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 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 any tenor of such Benchmark that is unavailable or non-representative for any Benchmark settings 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 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 notice to the Borrower by the Agent of the commencement of a Benchmark Unavailability Period and until a Benchmark Replacement is determined in accordance with this Section 2.23(b), the Borrower may revoke any request for a Term SOFR Advance or Daily Term SOFR Advance , or any request for the conversion or continuation of a Term SOFR Advance or Daily Term SOFR Advance to be made, converted or continued during any Benchmark Unavailability Period at the end of the applicable Interest Period, and, failing that, the Borrower will be deemed to have converted any such request at the end of the applicable Interest Period into a request for a Base Rate Advance or conversion to a Base Rate Advance. 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."

1.6 Manner of Funding. Section 2.28 is amended to read as follows:

"Section 2.28 [Intentionally omitted].

1.7 Restricted Payments. Section 6.7 is amended to read as follows:

"Alternate Base Rate" means, for any day, a rate of interest per annum equal to the highest of (a) zero, (b) the Prime Rate for such day, (c) the sum of the Federal Funds Effective Rate for such day plus 0.50% per annum and (d) the Term SOFR Rate (without giving effect to the Applicable Margin) for a one-month Interest Period on such day (or if such day is not a Business Day or if the Term SOFR Rate for such Business Day is not published due to a holiday or other circumstance that the Agent deems in its sole discretion to be temporary, the immediately preceding Business Day) for Dollars plus 1.00%. Any change in the Alternate Base Rate due to a change in the Prime Rate, the Federal Funds Effective Rate, or the Term SOFR Rate shall be effective from the effective date of such change. If the Alternate Base Rate is being used when Term SOFR Advances are unavailable pursuant to Section 2.6 or 2.23, then the Alternate Base Rate shall be the highest of clauses (a), (b) and (c) above, without reference to clause (d) above.

"Anti-Corruption Laws" means all laws, rules, and regulations of any jurisdiction applicable to the Borrower or its Subsidiaries from time to time concerning or relating to bribery or corruption.

Applicable Margins for Term SOFR Advances have been determined to be the sum of the credit margin, plus an index spread adjustment applicable to Term SOFR Advances that equals (i) 0.10% for Interest Periods of one month, (i) 0.15% for Interest Periods of three months, and (iii) 0.25% for Interest Periods of six months.

The minus sign (-) preceding certain of the foregoing percentages is intended to indicate a negative percentage.

During the period beginning on the date five days after the financial statements and Compliance Certificate for a fiscal quarter are required to be delivered pursuant to Sections 5.1(a), (c) and (d) but are not delivered and ending five days after the date such financial statements are delivered, the Applicable Commitment Fee Percentage and Applicable Margins shall be as specified for a Cash Flow Leverage Ratio greater than 2.25.

"Available Tenor" means, as of any date of determination and with respect to the then-current Benchmark, as applicable, (x) if the then-current Benchmark is a term rate, any tenor for such Benchmark that is or may be used for determining the length of an Interest Period or (y) otherwise, any payment period for interest calculated with reference to such Benchmark, as applicable, pursuant to this Agreement as of such date.

"Bank": As defined in the opening paragraph hereof.

"Base Rate" means, for any day, a rate per annum equal to (a) the Alternate Base Rate for such day plus (or minus, if negative) (b) the Applicable Margin for such day, in each case changing when and as the Alternate Base Rate or the Applicable Margin changes.

"Base Rate Advance" means a Loan that, except as otherwise provided in Section 2.6, bears interest at the Base Rate.

"Benchmark" means, initially, Term SOFR; provided that if a replacement of the Benchmark has occurred pursuant to Section 2.23(b), then "Benchmark" means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has become effective pursuant to Section 2.23(b).

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

(1)         Daily Simple SOFR; or

(2)         the sum of: (a) the alternate benchmark rate that has been selected by the 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 U.S. dollar-denominated syndicated credit facilities at such time and (b) the related Benchmark Replacement Adjustment.

If the Benchmark Replacement as determined pursuant to clause (1) or (2) 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 pursuant to clause (2) thereof for any applicable Interest Period and Available Tenor for any setting of such 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 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 U.S. dollar-denominated syndicated credit facilities.

"Benchmark Replacement Conforming Changes" means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of "Borrowing" and "Term SOFR Advance," the definition of "Alternate Base Rate," the definition of "Business Day," the definition of "Daily Term SOFR Advance", 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 Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Agent in a manner substantially consistent with market practice (or, if the Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Agent determines that no market practice for the administration of such Benchmark Replacement exists, in such other manner of administration as the 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 first date on which such Benchmark (or the published component used in the calculation thereof) has been determined and announced by the regulatory supervisor for the administrator of such Benchmark (or such component thereof) to be no longer representative; provided, that such non-representativeness will be determined by reference to the most recent statement or publication referenced in such clause (3) and even if any Available Tenor of such Benchmark (or such component thereof) continues to be provided on such date; and

(3) in the case of an Early Opt-in Election, the Business Day specified by the Agent in the notice of the Early Opt-in Election provided to the Banks, so long as the Agent has not received, by 5:00 p.m. (Central time) on the fifth Business Day after the date notice of such Early Opt-in Election is provided to the Banks, written notice of objection to such Early Opt-in Election from Banks comprising the Required Banks.

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:

(1) a public statement or publication of information by or on behalf of 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 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);

(2) 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), the Board of Governors of the Federal Reserve System, the Federal Reserve Bank of New York, an insolvency official with jurisdiction over the administrator for such Benchmark (or such component), a resolution authority with jurisdiction over the administrator for such Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for such 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 any of the entities referenced in clause (2) above announcing that all Available Tenors of such Benchmark (or such component thereof) are no longer, or as of a specified future date will no longer be, representative.

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).

"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 in accordance with Section 2.23(b), and (y) ending at the time that a Benchmark Replacement has replaced the then-current Benchmark in accordance with Section 2.23(b).

The 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 Term SOFR or other rates in the definition of Term SOFR Base Rate and Daily Term SOFR Base Rate, as applicable, or with respect to any alternative or successor rate thereto, or replacement rate thereof (including any Benchmark Replacement), including without limitation, whether any such alternative, successor or replacement reference rate (including any Benchmark Replacement), as it may or may not be adjusted pursuant to Section 2.23(b), will have the same value as, or be economically equivalent to, the Term SOFR Base Rate or Daily Term SOFR Base Rate, as applicable. The Agent and its affiliates or other related entities may engage in transactions that affect the calculation of Alternate Base Rate, Term SOFR, the Term SOFR Base Rate, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower. The Agent may select information sources or services in its reasonable discretion to ascertain the Alternate Base Rate, the Term SOFR Base Rate, Term SOFR or any other Benchmark, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Bank 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.
