Capitalized terms used and not defined in this Amendment have the meanings given to them in the Credit Agreement referred to below.

(b) The Borrower has requested certain modifications to the Credit Agreement and the Banks are willing to make such modifications, subject, however, to the terms, conditions and agreements set forth below.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Addition of Section 8.11 (Erroneous Payments). The following Section 8.11 is hereby added to the Credit Agreement:

8.11 Erroneous Payments.

(a) If the Agent notifies a Bank or other holder of any Debt (each, a “Lender Party”), or any Person who has received funds on behalf of a Lender Party (any such Lender Party or other recipient, a “Payment Recipient”), that the Agent has determined in its sole discretion (whether or not after receipt of any notice under Section 8.11(b)) that any funds received by such Payment Recipient from the Agent or any of its Affiliates were erroneously transmitted to, or otherwise erroneously received by, such Payment Recipient (whether or not such error is known to any Payment Recipient) (any such funds, whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and demands the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Agent, and such Payment Recipient shall promptly, but in no event later than two Business Days thereafter, return to the Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (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 Agent in same day funds at the greater of the Federal Funds Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation from time to time in effect. A notice of the Agent to any Payment Recipient under this clause (a) shall be conclusive, absent manifest error.

(b) Without limiting Section 8.11(a), if any Payment Recipient receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Agent (or any of its Affiliates) that (x) 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 Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Agent (or any of its Affiliates), or (z) such Payment Recipient otherwise becomes aware was transmitted, or received, in error (in whole or in part):

(A) in the case of immediately preceding clause (x) or (y), an error shall be presumed to have been made (absent written confirmation from the Agent to the contrary) or (B) in the case of immediately preceding clause (z), an error has been made, in each case, with respect to such payment, prepayment or repayment; and

such Payment Recipient shall promptly (and, in all events, within one Business Day of its knowledge of such error) notify the Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Agent pursuant to this Section 8.11(b).

(c) Each Lender Party hereby authorizes the Agent to set off, net and apply any and all amounts at any time owing to such Lender Party under any Credit Document, or otherwise payable or distributable by the Agent to such Lender Party from any source, against any amount due to the Agent under Section 8.11(a) or under the indemnification provisions of this Agreement.

(d) An Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Debt, except to the extent such Erroneous Payment comprises funds received by the Agent from the Borrower for the purpose of making such Erroneous Payment.

(e) To the extent permitted by applicable law, each Payment Recipient hereby agrees not to assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment, including without limitation any defense based on “discharge for value” or any similar doctrine, with respect to any demand, claim or counterclaim by the Agent for the return of any Erroneous Payment.

(f) Each party’s agreements under this Section 8.11 shall survive the resignation or replacement of the Agent, any transfer of rights or obligations by, or the replacement of, a Bank, the termination of the Commitments, or the repayment, satisfaction or discharge of any or all Debt.

2. Addition of Exhibit F. Exhibit F in the form attached as Exhibit F to this Amendment is hereby added to the Credit Agreement.

3. Failure to Comply with Covenants; Waiver; Release.

(a) Covenant Defaults. Borrower has advised the Banks that Borrower’s board of directors approved moving to a semi-annual and annual financial reporting structure. Because of this change, Borrower’s February 28, 2021, quarterly financial statements were not provided in accordance with Section 6.1(b)(1) of the Credit Agreement, which constitutes an Event of Default under Section 7.1(b) of the Credit Agreement (the “Covenant Defaults”). Borrower has requested that the Banks waive the Covenant Defaults.

(b) Waiver. Subject to the terms, conditions and restrictions set forth in this Amendment, the Banks waive the Covenant Defaults. For the avoidance of doubt, and notwithstanding anything in this Amendment that is or may appear to be to the contrary, the Banks do not waive any prior Default or Event of Default or any other Default or Event of Default under the Credit Agreement or other Credit Documents. Without limiting the generality of the foregoing, nothing in this Amendment shall waive the Borrower’s obligation to comply with any other covenant under the Credit Agreement, or any other Credit Document or the Borrower’s obligation to comply with Section 6.1(b)(1) of the Credit Agreement at any other time.

Seventh Amendment to Credit Agreement

(i) agrees that nothing in this Amendment shall constitute a waiver of any Default or Event of Default now existing under the Credit Agreement or any other Credit Document (in each case other than the Covenant Defaults), and that nothing in this Amendment shall impose any duty at any time on the Banks to waive any prior Default or Event of Default or any other Default or Event of Default under the Credit Agreement, whether such Default or Event of Default is similar to or different than the Covenant Defaults;

(ii) agrees that the matters set forth in this Amendment shall not discharge, limit or otherwise impair the obligations or liabilities of the Borrower, and that all obligations of the Borrower are enforceable against the Borrower in accordance with the terms of the Credit Agreement and the other Credit Documents; and

(iii) represents and warrants that (i) no Default or Event of Default under the Credit Agreement has occurred and is continuing or would exist after giving effect to this Amendment, and (ii) the Borrower does not have any defense, counterclaim or offset with respect to the Credit Agreement or the other Credit Documents.

(d) Release. The Borrower, for and on behalf of itself and its legal representatives, successors and assigns, does waive, release, relinquish and forever discharge the Agent and each Bank, and each of their parents, subsidiaries, and affiliates, its and their respective past, present and future directors, officers, managers, agents, employees, insurers, attorneys, representatives and all of their respective heirs, successors and assigns (collectively, the “Released Parties”), of and from any and all manner of action or causes of action, suits, claims, demands, judgments, damages, levies and executions of whatsoever kind, nature or description arising on or before the date of this Amendment, including, without limitation, any claims, losses, costs or damages, including compensatory and punitive damages, in each case whether known or unknown, asserted or unasserted, liquidated or unliquidated, fixed or contingent, direct or indirect, which the Borrower, or its legal representatives, successors or assigns, ever had or now has or may claim to have against any of the Released Parties, with respect to any matter whatsoever, including, without limitation, the Credit Documents, the administration of the Credit Documents, the negotiations relating to the Credit Agreement, this Amendment and the other Credit Documents executed in connection with the Credit Agreement and any other instruments and agreements executed by the Borrower in connection with the Credit Documents or this Amendment, arising on or before the date of this Amendment (collectively, “Claims”). The Borrower acknowledges that it is aware that it may discover facts different from or in addition to those it now knows or believes to be true with respect to the Claims, and agrees that the release contained in this Amendment is and will remain in effect in all respects as a complete and general release as to all matters released in this Amendment, notwithstanding any such different or additional facts. The Borrower agrees not to sue any Released Party or in any way assist any other person or entity in suing a Released Party with respect to any claim released in this Section.

4. Addition of Defined Terms. The following defined terms are hereby added to Section 1.1 of the Credit Agreement:

“Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark, as applicable, any tenor for such Benchmark or payment period for interest calculated with reference to such Benchmark, as applicable, that is or may be used for determining the length of an Interest Period pursuant to this Agreement as of such date and not including, for the avoidance of doubt, any tenor for such Benchmark that is then-removed from the definition of “Interest Period” pursuant to clause (v) of Section 3.20(b).

The definitions of “Benchmark Replacement,” “Benchmark Replacement Adjustment,” “Benchmark Replacement Conforming Changes,” “Benchmark Replacement Date,” “Benchmark Transition Event,” “Benchmark Unavailability Period,” “Libor Loan,” “Relevant Governmental Body,” and “Termination Date” set forth in Section 1.1 of the Credit Agreement are hereby deleted and are replaced with the following:

“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:

(3) 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;

provided that, in the case of clause (1), such Unadjusted Benchmark Replacement is displayed on a screen or other information service that publishes such rate from time to time as selected by the Agent in its reasonable discretion; provided further that, notwithstanding anything to the contrary in this Agreement or in any other Credit Document, upon the occurrence of a Term SOFR Transition Event, and the delivery of a Term SOFR Notice, on the applicable Benchmark Replacement Date the “Benchmark Replacement” shall revert to and shall be deemed to be the sum of (a) Term SOFR and (b) the related Benchmark Replacement Adjustment, as set forth in clause (1) of this definition (subject to the first proviso above). If the Benchmark Replacement as determined pursuant to clause (1), (2) or (3) above would be less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Credit Documents.

(2) for purposes of clause (3) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the 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;

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

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Libor Loan” and “Eurocurrency Borrowing,” the definition of “Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the 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 Credit Documents).

(1) in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of such Benchmark (or the published component used in the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof);

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

(3) in the case of a Term SOFR Transition Event, the date that is 30 days after the date a Term SOFR Notice is provided to the Banks and the Borrower so long as the Agent has not received, by such time, written notice of objection to such Term SOFR Notice from the Borrower; or

(4) in the case of an Early Opt-in Election, the sixth Business Day after the date notice of such Early Opt-in Election is provided to the Banks, so long as the Agent has not received, by 5:00 p.m. (Kansas City 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 the Banks.

Seventh Amendment to Credit Agreement

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 componentthereof); or

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

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 for all purposes hereunder and under any Credit Document in accordance with Section 3.20(b) and (y) ending at the time that a Benchmark Replacement has replaced the then-current Benchmark for all purposes hereunder and under any Credit Document in accordance with Section 3.20(b).

6. Modification of Section 3.20 (Inability to Determine Rates). Section 3.20 of the Credit Agreement is hereby deleted in its entirety and is replaced with the following:

3.20 Availability of Types of Borrowings; Adequacy of Interest Rate.

(a) Notwithstanding anything to the contrary in this Agreement or any other Credit Document, 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) deposits of a type and maturity appropriate to match fund Eurocurrency Borrowings or Daily Eurocurrency Loans are not available to such Banks in the relevant market, or

(ii) the interest rate applicable to Eurocurrency Borrowings or Daily Eurocurrency Loans for any requested Interest Period is not ascertainable or available (including, without limitation, because the applicable Reuters Screen (or on any successor or substitute page on such screen) is unavailable) or does not adequately and fairly reflect the cost of making or maintaining Eurocurrency Borrowings or Daily Eurocurrency Loans,

then the Agent shall suspend the availability of Eurocurrency Borrowings and Daily Eurocurrency Loans and require any affected Eurocurrency Borrowings and Daily Eurocurrency Loans to be repaid or converted to utilize the Base Rate inclusive of any margin as provided for in the Agreement.

(a) Benchmark Replacement.

(i) Benchmark Transition Event; Early Opt-in Election. Notwithstanding anything to the contrary herein or in any other Credit Document (and any swap agreement shall be deemed not to be a “Credit Document” for purposes of this Section 3.20(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) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Credit 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 Credit Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Credit 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 Credit 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) Term SOFR Transition Event. Notwithstanding anything to the contrary herein or in any other Credit Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Credit 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 Credit Document; provided that, this clause (b)(ii) shall not be effective unless the Agent has delivered to the Banks and the Borrower a Term SOFR Notice. For the avoidance of doubt, the Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may do so in its sole discretion.

Seventh Amendment to Credit Agreement

(iii) 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 Credit 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 Credit Document.

The Agent will promptly notify the Borrower and the Banks of (A) any occurrence of a Benchmark 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 clause (v) below and (E) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Agent or, if applicable, any Lender (or group of Banks) pursuant to this Section 3.20(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 Credit Document, except, in each case, as expressly required pursuant to this Section 3.20(b).

(v) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Credit Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i) if the then- current Benchmark is a term rate (including Term SOFR or LIBOR and/or the Libor 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” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(vi) Benchmark Unavailability Period. Upon notice to the Borrower by the Agent in accordance with Section 9.1 of the commencement of a Benchmark Unavailability Period and until a Benchmark Replacement is determined in accordance with this Section 3.20(b), the Borrower may revoke any request for a Eurocurrency Borrowing, or any request for the conversion or continuation of a Eurocurrency Borrowing 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 Base Rate Borrowing or conversion to a Base Rate Borrowing. 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 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 Base Rate.

7. Modification of Subsection (b) of Section 6.1 (Reporting Requirements). Subsection (b) of Section 6.1 of the Credit Agreement is hereby deleted in its entirety and is replaced with the following:

(b) Reporting Requirements. The Borrower shall furnish to the Agent:
