2.Amendment.  In reliance upon the representations and warranties set forth in Section 4 below and upon satisfaction of the conditions to effectiveness set forth in Section 3 below, the parties hereto agree to amend the Credit Agreement as follows:

(a)All references in the Credit Agreement and the Other Documents to “LIBOR Rate” are hereby amended to refer to “BSBY Rate,” all references to “LIBOR Rate Loan” are hereby amended to refer to “BSBY Loan” and all references to “Domestic Rate Loan” are hereby amended to refer to “ABR Loan”.

(c)The following defined terms appearing in Section 1.2 of the Credit Agreement are amended in their entirety to read as follows:

“Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus 0.50% per annum and (c) the Daily BSBY Rate in effect on such day plus 1.00% per annum, provided that the Alternate Base Rate shall at no time be less than 1.00% per annum.  If Agent shall have determined (which determination shall be conclusive absent clearly manifest error) that it is unable to ascertain the Federal Funds Rate or the Daily BSBY Rate for any reason, including the inability or failure of Agent to obtain sufficient quotations in accordance with the terms of the definition of the term Federal Funds Rate, the Alternate Base Rate shall be determined without regard to clause (b) or (c), as applicable, of the preceding sentence until the circumstances giving rise to such inability no longer exist.  Any change in the Alternate Base Rate due to a change in the Prime Rate, the Federal Funds Rate or the Daily BSBY Rate, as applicable, shall be effective from and including the effective date of such change in the Prime  Rate, the Federal Funds Rate or the Daily BSBY Rate, as applicable, respectively.

“Available Tenor(s)” means, as of any date of determination and with respect to the then-current Benchmark, as applicable, (x) if such Benchmark is a term rate, any tenor for such Benchmark (or component thereof) that is or may be used for determining the length of an interest period pursuant to this Agreement or the Note or (y) otherwise, any payment period for interest calculated with reference to such Benchmark (or component thereof) that is or may be used for determining any frequency of making payments of interest calculated with reference to such Benchmark pursuant to  this Agreement or the Note, in each case, 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 Section 3.9(b)(iv).

“Benchmark” means, initially, BSBY; provided that if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to BSBY 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 3.9(b)(i).  Any reference to “Benchmark” shall include, as applicable, the published component used in the calculation thereof.

(c)the sum of (i) the alternate benchmark rate that has been selected by Agent as the replacement for such Available Tenor of such Benchmark giving due consideration to any evolving or then-prevailing market convention for determining a benchmark rate and an adjustment as a replacement for the then-current Benchmark, including any recommendations made by a Relevant Governmental Body, for Dollar-denominated syndicated or bilateral credit facilities at such time and (ii) the related Benchmark Replacement Adjustment;

provided, that any such Benchmark Replacement shall be administratively feasible as determined by Agent in its sole discretion.  If the Benchmark Replacement as determined pursuant to clause (a), (b) or (c) above would be less than the Floor, such Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the Other Documents.

“Benchmark Replacement Adjustment”  means, with respect to any replacement of the then-current Benchmark with an Unadjusted 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 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;

“Benchmark Replacement Date” means a date and time determined by Agent, which date shall be no later than the earliest to occur of the following events with respect to the then-current Benchmark:

(a)in the case of clause (a) of the definition of “Benchmark Transition Event,” the later of (i) the date of the public statement or publication of information referenced therein and (ii) the date on which all Available Tenors of such Benchmark (or the published component used in the calculation thereof) are no longer available or permitted to be used for determining the interest rate of Dollar-denominated loans, or shall cease;

(b)in the case of clause (b) 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 or on behalf of (i) the administrator of such Benchmark (or such component thereof), (ii) the regulatory supervisor for the administrator of such Benchmark (or such component thereof) or (iii) a Governmental Authority exercising regulatory authority over the Agent or any Lender to be non-representative or not to be compliant with the International Organization of Securities Commissions (IOSCO) Principles for Financial Benchmarks; provided, that such non-representativeness or non-compliance, as the case may be, will be determined by reference to the most recent statement or publication referenced in such clause (b) and even if any Available Tenor of such Benchmark (or such component thereof) continues to be provided on such date; or

(c)in the case of clause (c) 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 or on behalf of the administrator of such Benchmark (or such component thereof) or the regulatory supervisor for the administrator of such Benchmark (or such component thereof) to be non-representative; provided that such non-representativeness will be determined by reference to the most recent statement or publication referenced in such clause (c) and even if any Available Tenor of such Benchmark (or such component thereof) continues to be provided on such date.

For the avoidance of doubt, if such Benchmark is a term rate, the “Benchmark Replacement Date” will be deemed to have occurred in the case of clauses (a), (b) or (c) 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 hereunder of such Benchmark (or the published component used in the calculation thereof).

(b)Each Interest Period of a BSBY Loan shall commence on the date such BSBY Loan is made.

(c)Borrower may, subject to the notice requirements set forth below, on any Business Day convert any Revolving Advance of one Type into a Revolving Advance of another Type in the same aggregate principal amount, provided that no Revolving Advance may be converted into a BSBY Loan if any Default or Event of Default shall have occurred and be continuing.  After giving effect to any borrowing or each such conversion, there shall not be outstanding more than four (4) BSBY Loans, in the aggregate.

(d)If any Default or Event of Default shall have occurred and be continuing, at the option of the Required Lenders, each BSBY Loan shall be deemed to convert to an ABR Loan on the last Business Day of the then-current Interest Period in effect with respect thereto.

(e)Borrower may prepay ABR Loans and BSBY Loans in whole at any time or in part from time to time with accrued interest on the principal being prepaid to the date of such repayment. In the event of (a) the payment or prepayment of any principal of any BSBY Loan other than on the last Business Day of the then-current Interest Period applicable thereto whether voluntary, mandatory, automatic, by reason of acceleration (including as a result of an Event of Default), (b) the conversion of any BSBY Loan other than on the last Business Day of the then-current Interest Period applicable thereto (including as a result of an Event of Default), (c) the failure to borrow, convert, continue or prepay any BSBY Loan on the date specified in any notice delivered pursuant hereto, then, in any such event, Borrower shall compensate Agent and Lender for any loss, cost and expense attributable to such event, including any loss, cost or expense arising from the liquidation or redeployment of funds.  A certificate of Agent or such Lender setting forth any amount or amounts that Agent or such Lender is entitled to receive

-11-

​

pursuant to this Section shall be delivered to Borrower and shall be conclusive absent manifest error.  Borrower shall pay Agent or such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(ii)Agent determines in its reasonable discretion that for any reason in connection with any request for a BSBY Loan or a conversion thereto or a continuation thereof that the BSBY Rate for any requested Interest Period with

-12-

respect to a proposed BSBY Loan does not adequately and fairly reflect the cost to Agent of funding such Loan for such Interest Period;

Agent will promptly so notify Borrower.

Upon notice thereof by Agent to Borrower, any obligation of Lenders to make BSBY Loans shall be suspended (to the extent of the affected Interest Periods) until Agent revokes such notice.  Upon receipt of such notice, (i) Borrower may revoke any pending request for a borrowing of, conversion to or continuation of BSBY Loans (to the extent of the affected Interest Periods) or, failing that, Borrower will be deemed to have converted any such request into a request for a Loan of or conversion to ABR Loans in the amount specified therein and (ii) any outstanding affected BSBY Loans will be deemed to have been converted into ABR Loans at the end of the applicable Interest Period.  Upon any such conversion, Borrower shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to this Agreement.  If Agent determines (which determination shall be conclusive and binding absent manifest error) that the “BSBY Rate” cannot be determined pursuant to the definition thereof on any given day, the interest rate on ABR Loans shall be determined by Agent without reference to clause (c) of the definition of “Alternate Base Rate” until Agent revokes such determination.

(iii)Notices; Standards for Decisions and Determinations.  Agent will promptly notify Borrower of (i) the implementation of any Benchmark Replacement and (iii) the effectiveness of any Conforming Changes in connection with the use, administration, adoption or implementation of a Benchmark Replacement.  The Agent will notify the Borrower of (x) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 3.9(b)(iv) and (y) the commencement or conclusion of any Benchmark Unavailability Period.  Any determination, decision or election that may be made by Agent pursuant to this Section 3.9(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 Document, except, in each case, as expressly required pursuant to this Section 3.9(b).

(iv)Unavailability of Tenor of Benchmark.  Notwithstanding anything to the contrary herein or in any Other 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 BSBY or Term SOFR) 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 Agent in its reasonable discretion, (B) the administrator of such Benchmark or a Governmental Authority having jurisdiction over such administrator with respect to its publication of such Benchmark or a Governmental Authority having jurisdiction over Agent or any Lender, in each case acting in such capacity, has provided a public statement or publication of information identifying a specific date after which any tenor shall or will no longer be made available, or permitted to be used for determining, the interest rate of Dollar-denominated loans, or (C) the administrator of such Benchmark or the regulatory supervisor for the administrator of such Benchmark has provided one or more public statements or publications of information (including by means of a technical note published on the BSBY Website) announcing or indicating in effect, that any tenor for such Benchmark is not or will not be representative or that a BSBY Final Step Event has occurred with respect to any tenor of such Benchmark, 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 impacted 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 described above, then 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 Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, Borrower may revoke any pending request for an Advance of, conversion to or continuation of BSBY Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, Borrower will be deemed to have converted any such request into a request for an Advance of or conversion to ABR Loans.  During a 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.

(j) Section 3.10 of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

3.10Increased Costs; Illegality.

(a)Increased Costs Generally.  If any Change in Law shall:

(i)impose, modify or deem applicable any reserve (including pursuant to regulations issued from time to time by the Federal Reserve Board for determining the maximum reserve requirement), special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any reserve requirement reflected in the BSBY Rate);

(ii)subject Agent or any Lender to any Taxes (other than Excluded Taxes or Indemnified Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)impose on any Lender any other condition, cost or expense (other than Taxes) affecting this Agreement or any Other Document made by any Lender(s) or any Letter of Credit;

and the result of any of the foregoing shall be to increase the cost to such Lender of making, converting to, continuing or maintaining any Revolving Advance or of maintaining its obligation to make any such Revolving Advance, or to increase the cost to such Lender of issuing or maintaining any Letter of Credit (or of maintaining its obligation to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b)Capital Requirements.  If Agent determines that any Change in Law affecting any Lender or any Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if

-15-

​

any, as a consequence of  the Note, the Loan Agreement, any commitment of any Lender to make an Advance, the Revolving Advances or any Letters of Credit issued by such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c)Certificates for Reimbursement.  A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to Borrower, shall be conclusive absent manifest error.  Borrower shall pay such Lender, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d)Delay in Requests.  Failure or delay on the part of a Lender to demand compensation pursuant to this Section shall not constitute a waiver of Agent’s or such Lender’s right to demand such compensation; provided, that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than nine months prior to the date that such Lender, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof.

(e)Illegality.  If Agent determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender to make, maintain or fund loans whose interest is determined by reference to BSBY or the BSBY Rate, or to determine or charge interest rates based upon BSBY or the BSBY Rate, then, upon notice thereof by Agent to Borrower, (a) any obligation of Agent to make BSBY Loans, and any right of Borrower to continue BSBY Loans shall be suspended, and (b) the interest rate on which ABR Loans shall, if necessary to avoid such illegality, be determined by Agent without reference to clause (c) of the definition of “Alternate Base Rate”, in each case until Agent notifies Borrower that the circumstances giving rise to such determination no longer exist.  Upon receipt of such notice, (i) Borrower shall, if necessary to avoid such illegality, upon demand from Agent or any Lender, prepay or, if applicable, convert all BSBY Loans to ABR Loans (the interest rate on which ABR Loans of Lender shall, if necessary to avoid such illegality, be determined by Agent without reference to clause (c) of the definition of “Alternate Base Rate”), on the last Business Day of the then-current Interest Period therefor in the case of BSBY Loans, if Lender may lawfully continue to maintain such BSBY Loans to such day, or immediately, if Lender may not lawfully continue to maintain such BSBY Loans to such day, and (ii) if necessary to avoid such illegality, Agent shall during the period of such

-16-

​

suspension compute the Alternate Base Rate without reference to clause (c) of the definition of “Alternate Base Rate” in each case until Agent determines that it is no longer illegal for Agent or any Lender to determine or charge interest rates based upon BSBY or the BSBY Rate.  Upon any such prepayment or conversion, Borrower shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to this Agreement.
