In the case of any Borrowing that the related Notice of Borrowing specifies is to comprise Eurodollar RateSOFR Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Section 3.02, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. (d) Unless the Administrative Agent shall have received notice in writing from a Lender prior to any Borrowing Date or, in the case of a Base Rate Advance, prior to the time of Borrowing, that such Lender will not make available to the Administrative Agent such Lender’s Advance as part of the Borrowing to be made on such Borrowing Date, the Administrative Agent may, but shall not be required to, assume that such Lender has made such portion available to the Administrative Agent on such Borrowing Date in accordance with subsection (a) of this Section 2.02, and the Administrative Agent may (but it shall not be required to), in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such Advance available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement. (e) The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing. SECTION 2.03 Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee equal to the product of (x) the Commitment Fee Rate in effect from time to time multiplied by (y) the amount of such Lender’s daily unused Commitment, in each case from (i) the Closing Date, in the case of each Initial Lender, and (ii) from the effective date specified in the Assignment and Assumption pursuant to which it became a Lender, in the case of each other Lender, payable quarterly in arrears on the last day of each March, June, September and December and on the Termination Date, commencing March 31, 2021, and ending on the Termination Date. AmericasActive:16835968.116835968.6

27 (b) The Borrower shall pay to the Administrative Agent such fees as may from time to time be agreed between the Borrower and the Administrative Agent, including pursuant to the Fee Letter. SECTION 2.04 Termination or Reduction of the Commitments. (a) The Borrower shall have the right, upon at least three Business Days’ notice to the Administrative Agent, to terminate in whole or reduce ratably in part the Commitments in an amount up to the amount by which the Commitments exceed the aggregate principal amount of all outstanding Advances at the time of such proposed termination or reduction; provided that each partial reduction shall be in a minimum amount of $1,000,000 or an integral multiple of $1,000,000 in excess thereof. (b) The Commitment of each Lender shall automatically terminate, if not previously terminated under the terms hereof, on the Termination Date. (c) Once terminated, neither a Commitment nor any portion thereof may be reinstated. SECTION 2.05 Repayment of Advances. The Borrower shall repay to the Administrative Agent for the account of each Lender on the Termination Date the aggregate principal amount of all Advances made by such Lender to the Borrower then outstanding. SECTION 2.06 Evidence of Indebtedness. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness to such Lender resulting from each Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement. (b) The Administrative Agent shall maintain accounts in which it will record (i) the amount of each Advance made hereunder, the Type of each Advance made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof. (c) The entries made in the accounts maintained pursuant to subsections (a) and (b) of this Section 2.06 shall, to the extent permitted by Applicable Law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Advances and interest thereon in accordance with the terms of this Agreement. (d) Any Lender may request that any Advances made by it be evidenced by one or more promissory notes. In such event, the Borrower shall prepare, execute and deliver to AmericasActive:16835968.116835968.6 28 such Lender one or more promissory notes payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Advances evidenced by such promissory notes and interest thereon shall at all times (including after assignment pursuant to Section 8.07) be represented by one or more promissory notes in such form payable to the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). SECTION 2.07 Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum: (a) Base Rate Advances. During such periods as such Advance is a Base Rate Advance, a rate per annum equal at all times to the sum of (x) the Base Rate plus (y) the Applicable Margin for Base Rate Advances in effect from time to time, payable in arrears (i) quarterly on the last day of each March, June, September and December during such periods, (ii) on the date such Base Rate Advance shall be Converted or paid in full and (iii) on the Termination Date. (b) Eurodollar RateSOFR Advances. During such periods as such Advance is a Eurodollar RateSOFR Advance, a rate per annum equal at all times during each Interest Period for such Advance to the sum of (x) the Eurodollar RateAdjusted Term SOFR for such Interest Period for such Advance plus (y) the Applicable Margin for Eurodollar RateSOFR Advances in effect from time to time, payable in arrears (i) on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period, (ii) on the date such Eurodollar Rate Advance shall be Converted or paid in full and (iii) on the Termination Date. (c) Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Administrative AgentTerm SOFR Conforming Changes. In connection with the use or administration of Term SOFR, 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. 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. AmericasActive:16835968.116835968.6

29 SECTION 2.08 Interest Rate Determination. (a) The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.07(a) or (b). (b) If, with respect to any Eurodollar RateSOFR Advances, (i) the Required Lenders notify the Administrative Agent that the Eurodollar RateAdjusted Term SOFR for any Interest Period for such Advances will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar RateSOFR Advances for such Interest Period, or (ii) a Eurodollar RateAdjusted Term SOFR cannot be determined or is otherwise unavailable, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (A) each Eurodollar RateSOFR Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (B) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar RateSOFR Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. (c) If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar RateSOFR Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Administrative Agent will forthwith so notify the Borrower and the Lenders and such Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances. (d) On the date on which the aggregate unpaid principal amount of Eurodollar RateSOFR Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $10,000,000, such Advances shall automatically Convert into Base Rate Advances. (e) Upon the occurrence and during the continuance of any Event of Default, (i) each Eurodollar RateSOFR Advance comprising the same Borrowing will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar RateSOFR Advances shall be suspended. SECTION 2.09 Optional Conversion of Advances. The Borrower may on any Business Day, upon delivery of a Notice of Conversion to the Administrative Agent not later than 1:00 P.M. (New York City time) on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.08 and 2.12, Convert all or any part of Advances of one Type comprising the same Borrowing into Advances of the other Type or of the same Type but having a new Interest Period; provided, however, that any Conversion of Eurodollar RateSOFR Advances into Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar RateSOFR Advances, any Conversion of Base Rate Advances into Eurodollar RateSOFR Advances shall be in an amount not less than the minimum amount specified in Section 2.02(b), and no Conversion of any Advances shall result in more separate Borrowings consisting of Eurodollar RateSOFR AmericasActive:16835968.116835968.6 30 Advances than permitted under Section 2.02(b). Each such Notice of Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be Converted, and (iii) if such Conversion is into Eurodollar RateSOFR Advances, the duration of the initial Interest Period for each such Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower. SECTION 2.10 Optional Prepayments of Advances. The Borrower may, upon at least three Business Days’ notice, in the case of Eurodollar RateSOFR Advances, and upon notice not later than 11:00 A.M. (New York City time) on the date of prepayment, in the case of Base Rate Advances, to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and, if such notice is given, the Borrower shall prepay the outstanding principal amount of the Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in a minimum amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in the event of any such prepayment of a Eurodollar RateSOFR Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(d). SECTION 2.11 Increased Costs. (a) Increased Costs Generally. If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Eurodollar Rate Reserve Percentage); (ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (C) Connection Income 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 or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Advances made by such Lender or participation therein; and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Advance or of maintaining its obligation to make any such Advance, or to reduce the amount of any sum received or receivable by such Lender or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or other Recipient, the Borrower will pay to such Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered. AmericasActive:16835968.116835968.6

31 (b) Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any Applicable Lending Office of such Lender or such 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 any, as a consequence of this Agreement, the Commitments of such Lender or the Advances made by such Lender, to a level below that which such Lender or such Lender’s or 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 or liquidity), then from time to time the 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 subsection (a) or (b) of this Section and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay such Lender, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof. (d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of 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 incurred or reductions suffered more than 180 days prior to the date that such Lender 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 (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof). SECTION 2.12 Illegality. If due to any Change in Law it shall become unlawful or impossible for any Recipient (or its EurodollarSOFR Lending Office) to make, maintain or fund its Eurodollar RateSOFR Advances, and such Recipient shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Recipients and the Borrower, whereupon, until such Recipient notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Recipient to make Eurodollar RateSOFR Advances, or to Convert outstanding Advances into Eurodollar RateSOFR Advances, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section 2.12, such Recipient shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions applicable to such Recipient) to designate a different EurodollarSOFR Lending Office if such designation would avoid the need for giving such notice and would not, in the judgment of such Recipient, be otherwise disadvantageous to such Recipient. If such notice is given, each Eurodollar RateSOFR Advance of such Recipient then outstanding shall be Converted to a Base Rate Advance either (i) on the last day of the then current Interest Period applicable to such Eurodollar RateSOFR Advance if such Recipient may lawfully continue to maintain and fund such Advance to such day or (ii) immediately if such Recipient shall determine that it may not lawfully continue to maintain and fund such Advance to such day. AmericasActive:16835968.116835968.6 32 SECTION 2.13 Payments and Computations. (a) The Borrower shall make each payment to be made by it hereunder not later than 1:00 P.M. on the day when due in Dollars to the Administrative Agent at the Agent’s Account in same day funds without condition or deduction for any counterclaim, defense, recoupment or setoff. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or commitment fees ratably (other than amounts payable pursuant to Section 2.02(c), 2.11, 2.14, 8.04(d) and 8.16) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(c), from and after the effective date specified in such Assignment and Assumption, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. (b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder, after any applicable grace period, to charge from time to time against any or all of the Borrower’s accounts with such Lender any amount so due. (c) All computations of interest based on the rate referred to in clause (i) of the definition of the “Base Rate” contained in Section 1.01 shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar RateAdjusted Term SOFR or the Federal Funds Rate and of commitment fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or commitment fees are payable. Each determination by the Administrative Agent of an interest rate or commitment fees hereunder shall be conclusive and binding for all purposes, absent manifest error. (d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment fees, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar RateSOFR Advances to be made in the next following calendar month or on a date after the Termination Date, such payment shall be made on the next preceding Business Day. (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to a Lender hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date, and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower AmericasActive:16835968.116835968.6

33 shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate. SECTION 2.14 Taxes. (a) Defined Terms. For purposes of this Section 2.14, the term “Applicable Law” includes FATCA. (b) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 2.14) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made. (c) Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes. (d) Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 10 days after demand therefor, for and hold it harmless against the full amount of any Indemnified Taxes (including, without limitation, Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 2.14), payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. (e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 8.07(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses AmericasActive:16835968.116835968.6 34 arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this subsection (e). (f) Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.14, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. (g) Status of Lenders. (i) (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.14(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. (ii) Without limiting the generality of the foregoing, (A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax; (B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable: AmericasActive:16835968.116835968.6

35 (1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; (2) executed copies of IRS Form W-8ECI; (3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Internal Revenue Code, (x) a certificate substantially in the form of Exhibit C-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E; or (4) to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit C-2 or Exhibit C-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit C-4 on behalf of each such direct and indirect partner; (C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and AmericasActive:16835968.116835968.6 36 (D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. (E) Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so. (h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.14 (including by the payment of additional amounts pursuant to this Section 2.14), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.14 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this subsection (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this subsection (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this subsection (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This subsection shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. (i) FATCA Withholding.

37 obligation” within the meaning of Treasury Regulation Sections 1.1471-2(b)(2)(i) and 1.1471-2T(b)(2)(i). (j) Survival. Each party’s obligations under this Section 2.14 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document. SECTION 2.15 Mitigation Obligations; Replacement of Lenders. (a) Designation of a Different Applicable Lending Office. If any Lender delivers a notice pursuant to Section 2.12, requests compensation under Section 2.11, or the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different Applicable Lending Office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.11 or 2.14, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. (b) Replacement of Lenders. If any Lender delivers a notice pursuant to Section 2.12, requests compensation under Section 2.11, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14 and, in each case, such Lender has declined or is unable to designate a different Applicable Lending Office in accordance with subsection (a) above, or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 8.07), all of its interests, rights (other than its existing rights to payments pursuant to Section 2.11 or Section 2.14) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if such Lender accepts such assignment); provided that: (i) the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 8.07(b)(iv); (ii) such Lender shall have received payment of an amount equal to the outstanding principal amounts of its Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 8.04(d)) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts); AmericasActive:16835968.116835968.6 38 (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.11 or payments required to be made pursuant to Section 2.14, such assignment will result in a reduction in such compensation or payments thereafter; (iv) no Default shall have occurred and be continuing; (v) such assignment does not conflict with Applicable Law; and (vi) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent. A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. SECTION 2.16 Sharing of Payments, Etc.

The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.16 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. (b) If any Lender shall fail to make any payment required to be made by it hereunder to or for the account of the Administrative Agent, then the Administrative Agent may, in its discretion and notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender for the benefit of the Administrative Agent to satisfy such Lender’s obligations in respect of such payment until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under any such Section, in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

ARTICLE VII THE ADMINISTRATIVE AGENT SECTION 7.01 Appointment and Authorization. Each Lender hereby irrevocably appoints and authorizes the Administrative Agent to enter into each of the Loan Documents to which it is a party (other than this Agreement) on its behalf and to take such actions as Administrative Agent on its behalf and to exercise such powers under the Loan Documents as are delegated to Administrative Agent by the terms thereof, together with all such powers as are reasonably incidental thereto. Subject to the terms of Section 8.01 and to the terms of the other Loan Documents, Administrative Agent is authorized and empowered to amend, modify, or waive any provisions of this Agreement or the other Loan Documents on behalf of Lenders. The provisions of this Article 7 are solely for the benefit of Administrative Agent and Lenders and Borrower shall not have any rights as a third party beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement, Administrative Agent shall act solely as agent of Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for Borrower. Administrative Agent may perform any of its duties hereunder, or under the Loan Documents, by or through its own agents or employees. SECTION 7.02 Administrative Agent and Affiliates. Administrative Agent shall have the same rights and powers under the Loan Documents as any other Lender and may exercise or refrain from exercising the same as though it were not Administrative Agent, and Administrative Agent and its Affiliates may lend money to, invest in AmericasActive:16835968.116835968.6 52 and generally engage in any kind of business with Borrower or any Affiliate of Borrower as if it were not Administrative Agent hereunder. SECTION 7.03 Action by Administrative Agent. The duties of Administrative Agent shall be mechanical and administrative in nature. Administrative Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender. Nothing in this Agreement or any of the Loan Documents is intended to or shall be construed to impose upon Administrative Agent any obligations in respect of this Agreement or any of the Loan Documents except as expressly set forth herein or therein. SECTION 7.04 Consultation with Experts. Administrative Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. SECTION 7.05 Liability of Administrative Agent. Neither Administrative Agent nor any of its directors, officers, agents or employees shall be liable to any Lender for any action taken or not taken by it in connection with the Loan Documents, except that Administrative Agent shall be liable with respect to its specific duties set forth hereunder, but only to the extent of its own gross negligence or willful misconduct in the discharge thereof as determined by a final non-appealable judgment of a court of competent jurisdiction. Neither Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements specified in any Loan Document; (iii) the satisfaction of any condition specified in any Loan Document; (iv) the validity, effectiveness, sufficiency or genuineness of any Loan Document, any Lien purported to be created or perfected thereby or any other instrument or writing furnished in connection therewith; (v) the existence or non-existence of any Default or Event of Default; or (vi) the financial condition of Borrower. Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, statement, or other writing (which may be a bank wire, telex, facsimile or electronic transmission or similar writing) believed by it to be genuine or to be signed by the proper party or parties. Administrative Agent shall not be liable for any apportionment or distribution of payments made by it in good faith and if any such apportionment or distribution is subsequently determined to have been made in error the sole recourse of any Lender to whom payment was due but not made, shall be to recover from other Lenders any payment in excess of the amount to which they are determined to be entitled (and such other Lenders hereby agree to return to such Lender any such erroneous payments received by them). SECTION 7.06 Indemnification. Each Lender severally agrees to indemnify the Administrative Agent and each of its Related Parties (to the extent not promptly reimbursed by the Borrower and without limiting its obligation to do so) from and against such Lender’s ratable share (determined as provided below) AmericasActive:16835968.116835968.6

53 of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent or such Related Party in any way relating to or arising out of this Agreement or any action taken or omitted by such Person under this Agreement; provided, however, that no Lender shall be liable, as to the Administrative Agent or any of its Related Parties, for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of such Person as determined in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent and each of its Related Parties promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and reasonable expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Administrative Agent or such Related Party is not promptly reimbursed for such costs and expenses by the Borrower after request therefor and without limiting the Borrower’s obligation to do so. For purposes of this Section 7.06, the Lenders’ respective ratable shares of any amount shall be determined, at any time, according to the sum of (i) the aggregate principal amount of the Advances outstanding at such time and owing to the respective Lenders and (ii) the aggregate unused portions of their respective Commitments at such time. In the event that any Lender shall have failed to make any Advance as required hereunder, such Lender’s Commitment shall be considered to be unused for purposes of this Section 7.06 to the extent of the amount of such Advance. The failure of any Lender to reimburse the Administrative Agent or any of its Related Parties promptly upon demand for its ratable share of any amount required to be paid by the Lender to the Administrative Agent or such Related Party as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Administrative Agent or such Related Party for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Administrative Agent or such Related Party for such other Lender’s ratable share of such amount. If any indemnity furnished to Administrative Agent for any purpose shall, in the opinion of Administrative Agent, be insufficient or become impaired, Administrative Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against even if so directed by Required Lenders until such additional indemnity is furnished. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 7.06 shall survive the payment in full of principal, interest and all other amounts payable hereunder. SECTION 7.07 Right to Request and Act on Instructions. Administrative Agent may at any time request instructions from Lenders with respect to any actions or approvals which by the terms of this Agreement or of any of the Loan Documents Administrative Agent is permitted or desires to take or to grant, and if such instructions are promptly requested, Administrative Agent shall be absolutely entitled to refrain from taking any action or to withhold any approval and shall not be under any liability whatsoever to any Person for refraining from any action or withholding any approval under any of the Loan Documents until it shall have received such instructions from Required Lenders or all or such other portion of the Lenders as shall be prescribed by this Agreement. Without limiting the foregoing, no AmericasActive:16835968.116835968.6 54 Lender shall have any right of action whatsoever against Administrative Agent as a result of Administrative Agent acting or refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of Required Lenders (or all or such other portion of the Lenders as shall be prescribed by this Agreement) and, notwithstanding the instructions of Required Lenders (or such other applicable portion of the Lenders), Administrative Agent shall have no obligation to take any action if it believes, in good faith, that such action would violate Applicable Law or exposes Administrative Agent to any liability for which it has not received satisfactory indemnification in accordance with the provisions of Section 7.06. SECTION 7.08 Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under the Loan Documents. SECTION 7.09 Notice of Default. Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default except with respect to defaults in the payment of principal, interest and fees required to be paid to Administrative Agent for the account of Lenders, unless Administrative Agent shall have received written notice from a Lender or Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. Administrative Agent will notify each Lender of its receipt of any such notice. Administrative Agent shall take such action with respect to such Default or Event of Default as may be requested by Required Lenders (or all or such other portion of the Lenders as shall be prescribed by this Agreement) in accordance with the terms hereof. Unless and until Administrative Agent has received any such request, Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable or in the best interests of Lenders. SECTION 7.10 Successor Administrative Agent. Administrative Agent may at any time give notice of its resignation to the Lenders and Borrower. Upon receipt of any such notice of resignation, Required Lenders shall have the right, in consultation with Borrower, to appoint a successor Administrative Agent. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder and notice of such acceptance to the retiring Administrative Agent, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, the retiring Administrative Agent’s resignation shall become immediately effective and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder and under the other Loan Documents (if such resignation was not already effective and such duties and obligations not already discharged, as provided below in this AmericasActive:16835968.116835968.6

55 paragraph). The fees payable by Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between Borrower and such successor. If no such successor shall have been so appointed by Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders (but without any obligation) appoint a successor Administrative Agent. From and following the expiration of such thirty (30) day period, Administrative Agent shall have the exclusive right, upon one (1) Business Days’ notice to Borrower and the Lenders, to make its resignation effective immediately. From and following the effectiveness of such notice, (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (ii) all payments, communications and determinations provided to be made by, to or through Administrative Agent shall instead be made by or to each Lender directly, until such time as Required Lenders appoint a successor Administrative Agent as provided for above in this paragraph. The provisions of this Agreement shall continue in effect for the benefit of any retiring Administrative Agent and its sub-agents after the effectiveness of its resignation hereunder and under the other Loan Documents in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting or was continuing to act as Administrative Agent. SECTION 7.11 Return of Payments. If Administrative Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or will be received by Administrative Agent from Borrower and such related payment is not received by Administrative Agent, then Administrative Agent will be entitled to recover such amount from such Lender on demand without setoff, counterclaim or deduction of any kind, together with interest accruing on a daily basis at the Federal Funds Rate. If Administrative Agent determines at any time that any amount received by Administrative Agent under this Agreement must be returned to Borrower or paid to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement or any other Loan Document, Administrative Agent will not be required to distribute any portion thereof to any Lender. In addition, each Lender will repay to Administrative Agent on demand any portion of such amount that Administrative Agent has distributed to such Lender, together with interest at such rate, if any, as Administrative Agent is required to pay to Borrower or such other Person, without setoff, counterclaim or deduction of any kind. SECTION 7.12 Defaulting Lenders. The failure of any Defaulting Lender to make any Advance or any payment required by it hereunder shall not relieve any other Lender of its obligations to make such Advance or payment, but neither any other Lender nor Administrative Agent shall be responsible for the failure of any Defaulting Lender to make an Advance or make any other payment required hereunder. SECTION 7.13 Sharing of Payments AmericasActive:16835968.116835968.6 56 If any Lender shall obtain any payment or other recovery (whether voluntary, involuntary, by application of setoff or otherwise) on account of any Loan (other than pursuant to the terms of Section 8.16) in excess of its pro rata share of payments entitled pursuant to the other provisions of this Section 7.13, such Lender shall purchase from the other Lenders such participations in extensions of credit made by such other Lenders (without recourse, representation or warranty) as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably with each of them; provided, however, that if all or any portion of the excess payment or other recovery is thereafter required to be returned or otherwise recovered from such purchasing Lender, such portion of such purchase shall be rescinded and each Lender which has sold a participation to the purchasing Lender shall repay to the purchasing Lender the purchase price to the ratable extent of such return or recovery, without interest. Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this clause (e) may, to the fullest extent permitted by law, exercise all its rights of payment with respect to such participation as fully as if such Lender were the direct creditor of Borrower in the amount of such participation. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this clause (e) applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this clause (e) to share in the benefits of any recovery on such secured claim. SECTION 7.14 Right to Perform, Preserve and Protect. If Borrower fails to perform any obligation hereunder or under any other Loan Document, Administrative Agent itself may, but shall not be obligated to, cause such obligation to be performed at Borrower’s expense. Administrative Agent is further authorized by Borrower and the Lenders to make expenditures from time to time which Administrative Agent, in its reasonable business judgment, deems necessary or desirable to (i) preserve or protect the business conducted by Borrower or any portion thereof and/or (ii) enhance the likelihood of, or maximize the amount of, repayment of the Advances. Borrower hereby agrees to reimburse Administrative Agent on demand for any and all costs, liabilities and obligations incurred by Administrative Agent pursuant to this Section 7.14. Each Lender hereby agrees to indemnify Administrative Agent upon demand for any and all costs, liabilities and obligations incurred by Administrative Agent pursuant to this Section 7.14 and all such amounts shall be deemed to be included within and covered by the Borrower’s indemnification obligation more particularly described in Section 8.04(b) of this Agreement. SECTION 7.15 Additional Titled Agents. Except for rights and powers, if any, expressly reserved under this Agreement to any bookrunner, arranger or to any titled agent named on the cover page of this Agreement, other than Administrative Agent (collectively, the “Additional Titled Agents”), and except for obligations, liabilities, duties and responsibilities, if any, expressly assumed under this Agreement by any Additional Titled Agent, no Additional Titled Agent, in such capacity, has any rights, powers, liabilities, duties or responsibilities hereunder or under any of the other Loan Documents. Without limiting the foregoing, no Additional Titled Agent shall have nor be deemed to have a fiduciary relationship with any Lender. At any time that any Lender serving as an Additional Titled Agent shall have transferred to any other Person (other than any Affiliates) AmericasActive:16835968.116835968.6

57 all of its interests in the Advances and in the Commitment, such Lender shall be deemed to have concurrently resigned as such Additional Titled Agent. SECTION 7.16 Erroneous Payments. (a) Each Lender and any other party hereto hereby severally agrees that if (i) the Administrative Agent notifies (which such notice shall be conclusive absent manifest error) such Lender or any other Person that has received funds from the Administrative Agent or any of its Affiliates, either for its own account or on behalf of a Lender (each such recipient, a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion that any funds received by such Payment Recipient were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Payment Recipient) or (ii) any Payment Recipient receives any payment from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, as applicable, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, as applicable, or (z) that such Payment Recipient otherwise becomes aware was transmitted or received in error or by mistake (in whole or in part) then, in each case, an error in payment shall be presumed to have been made (any such amounts specified in clauses (i) or (ii) of this Section 7.16(a), whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise; individually and collectively, an “Erroneous Payment”), then, in each case, such Payment Recipient is deemed to have knowledge of such error at the time of its receipt of such Erroneous Payment; provided that nothing in this Section shall require the Administrative Agent to provide any of the notices specified in clauses (i) or (ii) above. Each Payment Recipient agrees that it shall not assert any right or claim to any Erroneous Payment, and hereby waives any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payments, including without limitation waiver of any defense based on “discharge for value” or any similar doctrine. (b) Without limiting the immediately preceding clause (a), each Payment Recipient agrees that, in the case of clause (a)(ii) above, it shall promptly notify the Administrative Agent in writing of such occurrence. (c) In the case of either clause (a)(i) or (a)(ii) above, such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and upon demand from the Administrative Agent such Payment Recipient shall (or, shall cause any Person who received any portion of an Erroneous Payment on its behalf to), promptly, but in all events no later than one Business Day thereafter, return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made in same day funds and in the currency so received, together with interest thereon in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation from time to time in effect. AmericasActive:16835968.116835968.6 58 (d) In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with immediately preceding clause (c), from any Lender that is a Payment Recipient or an Affiliate of a Payment Recipient (such unrecovered amount as to such Lender, an “Erroneous Payment Return Deficiency”), then at the sole discretion of the Administrative Agent and upon the Administrative Agent’s written notice to such Lender (i) such Lender shall be deemed to have made a cashless assignment of the full face amount of the portion of its Loans (but not its Commitments) of the relevant class with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) to the Administrative Agent or, at the option of the Administrative Agent, the Administrative Agent’s applicable lending affiliate in an amount that is equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Loans (but not Commitments) of the Erroneous Payment Impacted Class, the “Erroneous Payment Deficiency Assignment”) plus any accrued and unpaid interest on such assigned amount, without further consent or approval of any party hereto and without any payment by the Administrative Agent or its applicable lending affiliate as the assignee of such Erroneous Payment Deficiency Assignment. The parties hereto acknowledge and agree that (1) any assignment contemplated in this clause (d) shall be made without any requirement for any payment or other consideration paid by the applicable assignee or received by the assignor, (2) the provisions of this clause (d) shall govern in the event of any conflict with the terms and conditions of Section 8.07 and (3) the Administrative Agent may reflect such assignments in the Register without further consent or action by any other Person.

(f) Each party’s obligations under this Section 7.16 shall survive the resignation or replacement of the Administrative Agent or any transfer of right or obligations by, or the replacement of, a Lender, the termination of the Commitments or the repayment, satisfaction or discharge of all obligations hereunder (or any portion thereof) under any Loan Document. AmericasActive:16835968.116835968.6

59 (g) Nothing in this Section 7.16 will constitute a waiver or release of any claim of the Administrative Agent hereunder arising from any Payment Recipient’s receipt of an Erroneous Payment.

61 WITHOUT LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS), LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF THE BORROWER’S OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS FOUND IN A FINAL, NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. The Administrative Agent agrees that the receipt of the Communications by the Administrative Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Administrative Agent for purposes of the Loan Documents. Each Lender agrees that notice to it (as provided in the next sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (i) to notify the Administrative Agent in writing (including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address.

SECTION 8.03 No Waiver; Remedies. No failure on the part of any Lender or the Administrative Agent to exercise, and no delay in exercising, any right or power hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents are cumulative and not exclusive of any rights and remedies that are provided by law or that they would otherwise have. SECTION 8.04 Costs and Expenses; Indemnification. (a) The Borrower agrees to pay promptly upon demand all reasonable out-of-pocket costs and expenses of the Administrative Agent and the Arrangers in connection with the preparation, execution, delivery, administration, modification and amendment of this Agreement and the other documents to be delivered hereunder, including, without limitation, (i) all due diligence, syndication (including printing, distribution and bank meetings), transportation, computer, electronic data site, duplication, appraisal, consultant, and audit expenses and (ii) the reasonable fees and expenses of counsel for the Administrative Agent with respect thereto and with respect to advising the Administrative Agent as to its rights and responsibilities under this Agreement.

(b) The Borrower agrees to indemnify and hold harmless each Lender, the Arrangers and the Administrative Agent and each of their Related Parties (each, an “Indemnified Party”) from and against any and all claims, damages, losses, liabilities and penalties, joint or several, to which any such Indemnified Party may become subject, in each case arising out of or in connection with or relating to (including, without limitation, in connection with any actual or prospective claim, investigation, litigation or proceeding or preparation of a defense in connection therewith) (i) the execution or delivery of this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances, (ii) any error or omission in connection with posting of data (x) required to be delivered pursuant to Section 5.01(i)(i), (ii) or (iv) on the website of the SEC or any successor website or (y) on the Platform, or (iii) the actual or alleged presence of Hazardous Materials on any property of the Borrower or any of its Subsidiaries or any Environmental Action relating in any way to the Borrower or any of its Subsidiaries, and to reimburse any Indemnified Party for any and all reasonable expenses (including, without limitation, reasonable fees and expenses of counsel) as they are incurred in connection with the investigation of or preparation for or defense of any pending or threatened actual or prospective claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party and whether or not such claim, action or proceeding is initiated or brought by or on behalf of the Borrower or any of its Affiliates and whether or not any of the transactions contemplated hereby are consummated or this Agreement is terminated, AND THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH INDEMNIFIED LIABILITIES ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY INDEMNIFIED PERSON, except to the extent such claim, damage, loss, liability, penalty or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, its managers, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. To the fullest extent permitted by applicable law, the Borrower agrees not to assert, or permit any of their Affiliates or Related Parties to assert, and each hereby waives, any claim against any Indemnified Party on any theory of liability, for special, indirect, or punitive damages (as opposed to direct or actual damages) arising out of or otherwise relating to this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Borrowings. (c) To the fullest extent permitted by applicable law, the Borrower agrees not to assert, or permit any of their Affiliates or Related Parties to assert, and each hereby waives, any claim against any Indemnified Party on any theory of liability, for consequential damages (including lost profits) arising out of or otherwise relating to this Agreement, any of the AmericasActive:16835968.116835968.6

63 transactions contemplated herein or the actual or proposed use of the proceeds of the Borrowings.

(e) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.11, 2.14 and 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder. (f) The Borrower agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Borrower or its security holders or creditors related to or arising out of or in connection with this Agreement, the Borrowings or the use or proposed use of the proceeds thereof, any of the transactions contemplated by any of the foregoing or in the loan documentation or the performance by an Indemnified Party of any of the foregoing (including the use by unintended recipients of any information or other materials distributed through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents) except to the extent that any loss, claim, damage, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct. (g) In the event that an Indemnified Party is requested or required to appear as a witness in any action brought by or on behalf of or against the Borrower or any of its Affiliates in which such Indemnified Party is not named as a defendant, the Borrower agrees to reimburse such Indemnified Party for all reasonable expenses incurred by it in connection with such Indemnified Party’s appearing and preparing to appear as such a witness, including, without limitation, the fees and disbursements of its legal counsel.

Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the outstanding Borrowings due and payable pursuant to the provisions of Section 6.01, each Recipient and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all AmericasActive:16835968.116835968.6 64 deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Recipient or such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement held by such Recipient, whether or not such Recipient shall have made any demand under this Agreement and although such obligations may be unmatured; provided that, in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 8.16 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the obligations of the Borrower owing to such Defaulting Lender as to which it exercised such right of setoff. Each Recipient agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Recipient and its Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Recipient and its Affiliates may have. SECTION 8.06 Binding Effect. This Agreement shall become effective upon satisfaction of the conditions precedent specified in Section 3.01 and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of all of the Lenders. Neither the Arrangers nor any Person designated as a “Documentation Agent” or a “Syndication Agent” with respect to this Agreement shall have any duties under this Agreement. SECTION 8.07 Assignments and Participations. (a) Successors and Assigns of Lenders Generally. No Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (e) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. (b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Advances at the time owing to it); provided that any such assignment shall be subject to the following conditions: (i) Minimum Amounts. AmericasActive:16835968.116835968.6

65 (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and/or the Advances at the time owing to it or contemporaneous assignments to related Approved Funds that equal at least the amount specified in subsection (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and (B) in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment and/or Advances of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if the “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof, unless each of the Administrative Agent and, so long as no Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed). (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Advances or the Commitment of such Lender being assigned. (iii) Required Consents. No consent shall be required for any assignment except to the extent required by subsection (b)(i)(B) of this Section and, in addition: (A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) a Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 10 Business Days after having received notice thereof; and (B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of (i) any unfunded Commitments if such assignment is to a Person that is not a Lender with a Commitment, an Affiliate of such Lender or an Approved Fund with respect to such Lender, or (ii) any Advance to a Person that is not a Lender, an Affiliate of a Lender or an Approved Fund, (iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 (to be paid by the assigning Lender, or, in the case of an assignment pursuant to Section 2.15(b), the Borrower); provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. AmericasActive:16835968.116835968.6 66 (v) No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any of the Borrower’s Affiliates or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person that, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B). (vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person). (vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent and each Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Advances and Commitments in accordance with its Commitment Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under Applicable Law without compliance with the provisions of this subsection, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs. Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.11, 2.14 and 8.04 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed in writing by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section. AmericasActive:16835968.116835968.6

67 (c) Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Assumption delivered to it and a register in which it shall record the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. (d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person, or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Advances owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity obligations under Section 7.06 with respect to any payments made by such Lender to its Participant(s). Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver with respect to clauses (i) through (vi) of Section 8.01 that affects such participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.02(c), 2.11, 2.14, 8.04(b), 8.04(c) and 8.04(d) (subject to the requirements and limitations therein, including the requirements under Section 2.14(f) (it being understood that the documentation required under Section 2.14(f) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 2.15(b) as if it were an assignee under subsection (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.11 or 2.14, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower's request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.15(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.16 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it AmericasActive:16835968.116835968.6 68 enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Advances or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any Commitments, Advances or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Advance or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.

Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender pursuant to this Section 8.16(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

To the extent that the Loan Documents provide support, through a guarantee or otherwise, for swap contracts or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and each such QFC a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): (a) If a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. If a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support. (b) As used in this Section, the following terms have the following meanings: “BHC Act Affiliate” of a party means an “affiliate” (as such term is defined under, and interpreted in accordance with, 12 U.S.C. 1841(k)) of such party. AmericasActive:16835968.116835968.6 80 “Covered Entity” means any of the following: (a) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (b) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (c) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “QFC” has the meaning assigned to the term “qualified financial contract” in, and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D).

Very truly yours, PUBLIC SERVICE COMPANY OF OKLAHOMA By Name: Title: AmericasActive:16836356.8 Exhibit D FORM OF OPINION OF COUNSEL FOR THE BORROWER To each of the Lenders party to the First Amendment to Credit Agreement referred to below and to Sumitomo Mitsui Banking Corporation, as Administrative Agent thereunder April 19, 2022 Ladies and Gentlemen: This opinion is furnished to you pursuant to Section 2(a)(iii) of the First Amendment to Credit Agreement, dated as of April 19, 2022 (the “First Amendment”) PUBLIC SERVICE COMPANY OF OKLAHOMA, an Oklahoma corporation (the “Borrower”), the Lenders party thereto and Sumitomo Mitsui Banking Corporation, as Administrative Agent. Terms defined in the First Amendment and Credit Agreement are used herein as therein defined. I am Associate General Counsel for American Electric Power Service Corporation, an affiliate of the Borrower, and have acted as counsel to the Borrower in connection with the preparation, execution and delivery of the First Amendment. I am generally familiar with the Borrower’s corporate history, properties, operations and charter (including amendments, restatements and supplements thereto). In connection with this opinion, I, or attorneys over whom I exercise supervision, have examined: (1) The Credit Agreement (the “Loan Document”). (2) The First Amendment. (3) The documents furnished by the Borrower pursuant to Section 2 of the First Amendment. (4) The certificate of incorporation of the Borrower and all amendments thereto. (5) The by-laws of the Borrower and all amendments thereto. (6) A certificate of the Secretary of State of the State of Oklahoma, dated April 18, 2022, attesting to the continued existence and good standing of the Borrower in that State. In addition, I, or attorneys over whom I exercise supervision, have examined the originals, or copies certified to my satisfaction, of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as I have deemed necessary as a basis for the opinions expressed below.

AmericasActive:16836356.8 In my examination, I, or attorneys over whom I exercise supervision, have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. In making our examination of documents and instruments executed or to be executed by persons other than the Borrower, I, or attorneys over whom I exercise supervision, have assumed that each such other person had the requisite power and authority to enter into and perform fully its obligations thereunder, the due authorization by each such other person for the execution, delivery and performance thereof and the due execution and delivery thereof by or on behalf of such person of each such document and instrument. In the case of any such person that is not a natural person, I, or attorneys over whom I exercise supervision, have also assumed, insofar as it is relevant to the opinions set forth below, that each such other person is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it was created and is duly qualified and in good standing in each other jurisdiction where the failure to be so qualified could reasonably be expected to have a material effect upon its ability to execute, deliver and/or perform its obligations under any such document or instrument. I, or attorneys over whom I exercise supervision, have further assumed that each document, instrument, agreement, record and certificate reviewed by us for purposes of rendering the opinions expressed below has not been amended by any oral agreement, conduct or course of dealing between the parties thereto. As to questions of fact material to the opinions expressed herein, I have relied upon certificates and representations of officers of the Borrower (including but not limited to those contained in the First Amendment and certificates delivered upon the execution and delivery of the First Amendment) and of appropriate public officials, without independent verification of such matters except as otherwise described herein. Whenever my opinions herein with respect to the existence or absence of facts are stated to be to my knowledge or awareness, it is intended to signify that no information has come to my attention or the attention of other counsel working under my direction in connection with the preparation of this opinion letter that would give me or them actual knowledge of the existence or absence of such facts. However, except to the extent expressly set forth herein, neither I nor they have undertaken any independent investigation to determine the existence or absence of such facts, and no inference as to my or their knowledge of the existence or absence of such facts should be assumed. I am a member of the Bar of the States of New York and Ohio and do not purport to be expert on the laws of any jurisdiction other than the laws of the States of New York and Ohio and the Federal laws of the United States and, for purposes of this opinion only, the State of Oklahoma. My opinions expressed below are limited to the law of the States of Oklahoma, New York and Ohio and the Federal law of the United States. Based upon the foregoing and upon such investigation as I have deemed necessary, and subject to the limitations, qualifications and assumptions set forth herein, I am of the following opinion: 1. The Borrower (a) is a corporation duly organized, validly existing and in good standing under the laws of the State of Oklahoma; (b) has the corporate power and authority, and the legal right, to own and operate its property, to lease the property which it operates as lessee and to conduct the business in which it is currently engaged and in which it proposes to be engaged after the date hereof; (c) is duly AmericasActive:16836356.8 qualified as a foreign corporation and is in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, except any such jurisdiction where the failure to so qualify could not, in the aggregate, reasonably be expected to result in a Material Adverse Change; (d) owns or possesses all material licenses and permits necessary for the operation by it of its business as currently conducted; and (e) is in compliance with all Requirements of Law, except as disclosed in the Amendment Disclosure Documents referenced in Section 2(g) of the First Amendment or to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. The term “Requirements of Law” means the laws of the State of Oklahoma and the laws, rules and regulations of the United States of America (including, without limitation, ERISA and Environmental Laws) and orders of any governmental authority applicable to the Borrower. 2. The Borrower has the corporate power and authority, and the legal right, to execute and deliver the First Amendment and to perform its obligations under each First Amendment and the Loan Document, and to borrow under the Credit Agreement. The Borrower has taken all necessary corporate action to authorize the execution, delivery and performance of the First Amendment and the Loan Document and the incurrence of Advances on the terms and conditions of the Credit Agreement, and the First Amendment and the Loan Document has been duly executed and delivered by the Borrower. The First Amendment and the Loan Document constitutes the valid and legally binding obligation of the Borrower enforceable against the Borrower in accordance with its terms 3. The execution, delivery and performance of the First Amendment and the Loan Document and the Advances made under the Credit Agreement will not violate any Requirements of Law, the Borrower's certificate of incorporation or by-laws, or any material contractual restriction binding on or affecting the Borrower or any of its properties. 4. No approval or authorization or other action by, and no notice to or filing with, any governmental agency or regulatory body or other third person is required in connection with the due execution and delivery of the First Amendment or the Loan Document and the performance, validity and enforceability of the First Amendment and the Loan Document except for the authorization of the Corporation Commission of Oklahoma, which authorization has been obtained and is in full force and effect on the date hereof. 5. Except as described in Section 4.01(e) of the Credit Agreement, no action, suit, investigation, litigation, or proceeding, including, without limitation, any Environmental Action, affecting the Borrower or any of its Significant Subsidiaries before any court, government agency or arbitrator is pending or, to my knowledge, threatened, that is reasonably likely to have a Material Adverse Effect.

AmericasActive:16836356.8 6. Neither the Borrower nor any of its Significant Subsidiaries is an “investment company”, or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the Investment Company Act of 1940, as amended (the “1940 Act”). Neither the making of any Advances, the application of the proceeds or repayment thereof by the Borrower nor the consummation of the other transactions contemplated by the Credit Agreement will violate any provision of the 1940 Act or any rule, regulation or order of the Securities and Exchange Commission thereunder. The opinion set forth above in the last sentence of paragraph 2 above is subject to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally and to general principles of equity, including (without limitation) concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law.) I express no opinion as to (i) Section 8.05 of the Credit Agreement; (ii) the effect of the law of any jurisdiction (other than the State of Oklahoma) wherein any Lender may be located which limits the rates of interest which may be charged or collected by such Lender; and (iii) whether a federal or state court outside of the States of Oklahoma and New York would give effect to the choice of New York law provided for in the Credit Agreement. This opinion letter has been rendered solely for your benefit in connection with the First Amendment and the transactions contemplated thereby and may not be used, circulated, quoted, relied upon or otherwise referred to by any other person (other than your respective counsel, auditors and any regulatory agency having jurisdiction over you or as otherwise required pursuant to legal process or other requirements of law) for any other purpose without my prior written consent; provided that, any person that becomes a Lender after the date hereof may rely on the opinions expressed in this opinion letter as though addressed to such person. I undertake no responsibility to update or supplement this opinion in response to changes in law or future events or circumstances. Very truly yours, Xxxxx X.
