All such notices concerning the advance, continuation, or conversion of a Borrowing shall be irrevocable once given and shall specify the date of the requested advance, continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be advanced, continued, or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. The Borrower agrees that the Administrative Agent may rely on any such telephonic or telecopy notice given by any person it in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts with any written confirmation, such telephonic notice shall govern if the Administrative Agent has acted in reliance thereon. There may be no more than ten (10) different Interest Periods in effect at any one time, provided that for purposes of determining the number of Interest Periods in effect at any one time, all Base Rate Loans shall be deemed to have one and the same Interest Period.

b.Notice to the Banks. The Administrative Agent shall give prompt telephonic or telecopy notice to each Bank of any Borrowing Notice or Conversion/Continuation Notice from the Borrower received pursuant to Section 2.5(a). The Administrative Agent shall give notice to the Borrower and each Bank by like means of the interest rate applicable to each Borrowing of Eurodollar Loans.

c.Borrower’s Failure to Notify. Any outstanding Borrowing of Base Rate Loans shall, subject to Section 6.2 hereof, automatically be continued for an additional Interest Period on the last day of its then current Interest Period unless the Borrower has notified the Administrative Agent within the period required by Section 2.5(a) hereof that it intends to convert such Borrowing into a Borrowing of Eurodollar Loans or notifies the Administrative Agent within the period required by Section 2.8(a) hereof that it intends to prepay or repay such Borrowing. If the Borrower fails to give notice pursuant to Section 2.5(a) hereof of the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans before the last day of its then current Interest Period within the period required by Section 2.5(a) hereof and has not notified the Administrative Agent within the period required by Section 2.8(a) hereof that it intends to prepay such Borrowing, such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans, subject to Section 6.2 hereof. The Administrative Agent shall promptly notify the Banks of the Borrower’s failure to so give a notice under Section 2.5(a) hereof.

d.Disbursement of Loans. Not later than 12:00 noon (New York time) on the date of any requested advance of a new Borrowing of Eurodollar Loans, and not later than 2:00 p.m. (New York time) on the date of any requested advance of a new Borrowing of Base Rate Loans, subject to Section 6 hereof, each Bank shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent.

The Administrative Agent shall make available to the Borrower Loans in the type of funds received by the Administrative Agent from the Banks.

e.Administrative Agent Reliance on Bank Funding. Unless the Administrative Agent shall have been notified by a Bank (i) with respect to Eurodollar Loans, before the date on which such Bank is scheduled to make payment to the Administrative Agent of the proceeds of a Loan (which notice shall be effective upon receipt) or (ii) with respect to Base Rate Loans, no later than 2:00 p.m. (New York time) on the due date thereof, that such Bank does not intend to make such payment, the Administrative Agent may assume that such Bank has made such payment when due and the Administrative Agent may in reliance upon such assumption (but shall not be required to) make available to the Borrower the proceeds of the Loan to be made by such Bank and, if any Bank has not in fact made such payment to the Administrative Agent, such Bank shall, on demand, pay to the Administrative Agent the amount made available to the Borrower attributable to such Bank together with interest thereon in respect of each day during the period commencing on the date such amount was made available to the Borrower and ending on (but excluding) the date such Bank pays such amount to the Administrative Agent at a rate per annum equal to (i) from the date the related payment was made by the Administrative Agent to the date two (2) Business Days after payment by such Bank is due hereunder, the NYFRB Rate for each such day and (ii) from the date two (2) Business Days after the date such payment is due from such Bank to the date such payment is made by such Bank, the Base Rate in effect for each such day. If such amount is not received from such Bank by the Administrative Agent immediately upon demand, the Borrower will, on demand, repay to the Administrative Agent the proceeds of the Loan attributable to such Bank with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan.

Section 2.6     Interest Periods. As provided in Section 2.5(a) hereof, at the time of each request for a Borrowing of Eurodollar Loans, the Borrower shall select an Interest Period applicable to such Loans from among the available options. The term “Interest Period” means the period commencing on the date a Borrowing of Loans is advanced, continued, or created by conversion and ending: (a) in the case of Base Rate Loans, on the last Business Day of the calendar quarter in which such Borrowing is advanced, continued, or created by conversion (or on the last day of the following calendar quarter if such Loan is advanced, continued or created by conversion on the last Business Day of a calendar quarter) and (b) in the case of Eurodollar Loans, 1, 2, 3 or 6 months thereafter (or such other time period as may be agreed to by and among the Borrower, the Administrative Agent and the Banks); provided, however, that:

a.any Interest Period for a Borrowing of Base Rate Loans that otherwise would end after the Termination Date shall end on the Termination Date;

b.for any Borrowing of Eurodollar Loans, the Borrower may not select an Interest Period that extends beyond the Termination Date;

c.whenever the last day of any Interest Period would otherwise be a day that is not a Business Day, the last day of such Interest Period shall be extended to the next succeeding Business Day, provided that, if such extension would cause the last day of an Interest Period for a Borrowing of Eurodollar Loans to occur in the following calendar month, the last day of such Interest Period shall be the immediately preceding Business Day; and

d.for purposes of determining an Interest Period for a Borrowing of Eurodollar Loans, a month means a period starting on one day in a calendar month and ending on the numerically corresponding day in the next calendar month; provided, however, that if there is no numerically corresponding day in the month in which such an Interest Period is to end or if such

an Interest Period begins on the last Business Day of a calendar month, then such Interest Period shall end on the last Business Day of the calendar month in which such Interest Period is to end.

Section 2.7    Maturity of Loans. Unless an earlier maturity is provided for hereunder (whether by acceleration or otherwise), all Obligations (including principal and interest on all outstanding Loans) shall mature and become due and payable by the Borrower on the Termination Date.

Section 2.8    Prepayments. The Borrower may prepay any Borrowing of Eurodollar Loans or Base Rate Loans without premium or penalty and in whole or in part (but, if in part, then (i) in an amount not less than $1,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) in an amount such that the minimum amount required for a Borrowing pursuant to Section 2.4 hereof remains outstanding) upon irrevocable notice to the Administrative Agent in the form of Exhibit E-3 (a “Paydown Notice”) (A) in the case of any Borrowing of Eurodollar Loans, no later than 2:00 p.m. (New York time) on the date that is three (3) Business Days’ prior to such prepayment and (B) in the case of any Borrowing of Base Rate Loans, no later than 2:00 p.m. (New York time) on the date of such prepayment, such prepayment to be made by the payment of the principal amount to be prepaid and accrued interest thereon to the date fixed for prepayment. In the case of Eurodollar Loans, any amounts owing under Section 2.11 hereof as a result of such prepayment shall be paid contemporaneously with such prepayment. The Administrative Agent will promptly advise each Bank of any such prepayment notice it receives from the Borrower. No amount paid or prepaid before the Termination Date may be borrowed again.

Section 2.9    Default Rate. If any payment of principal or interest on any Loan, or payment of any other Obligation, is not made when due (whether by acceleration or otherwise), such principal, interest or other Obligation shall bear interest (computed on the basis of a year of 360 days and actual days elapsed or, if based on the Base Rate, on the basis of a year of 365 or 366 days, as applicable, and the actual number of days elapsed) from the date such payment was due until paid in full, payable on demand, at a rate per annum equal to:

a.for any Obligation other than a Eurodollar Loan (including principal and interest relating to Base Rate Loans and interest on Eurodollar Loans), the sum of two percent (2.00%) plus the Applicable Margin plus the Base Rate from time to time in effect; and

b.for the principal of any Eurodollar Loan, the sum of two percent (2.00%) plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of two percent (2.00%) plus the Applicable Margin plus the Base Rate from time to time in effect.

Section 2.10    The Notes.

a.The Loans made to the Borrower by each Bank shall, upon the written request of any such Bank, be evidenced by a single promissory note of the Borrower issued to such Bank in the form of Exhibit A hereto. Each such promissory note is hereinafter referred to as a “Note” and collectively such promissory notes are referred to as the “Notes.”

b.Each Bank shall record on its books and records or on a schedule to its Note (if any) the amount of each Loan advanced, continued, or converted by it, all payments of principal and interest and the principal balance from time to time outstanding thereon, the type of such Loan, and, for any Eurodollar Loan, the Interest Period and the interest rate applicable thereto. The record thereof, whether shown on such books and records of a Bank or on a schedule to any Note, shall be prima facie evidence of the same; provided, however, that the failure of any Bank

to record any of the foregoing or any error in any such record shall not limit or otherwise affect the obligation of the Borrower to repay all Loans made hereunder together with accrued interest thereon. At the written request of any Bank and upon such Bank tendering to the Borrower the Note to be replaced, the Borrower shall furnish a new Note to such Bank to replace any outstanding Note, and at such time the first notation appearing on a schedule on the reverse side of, or attached to, such Note shall set forth the aggregate unpaid principal amount of all Loans, if any, then outstanding thereon.

Section 2.11    Funding Indemnity. If any Bank shall incur any loss, cost or expense (including, without limitation, any loss, cost or expense (excluding loss of margin) incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Bank to fund or maintain any Eurodollar Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to such Bank) as a result of:

a.any payment (whether by acceleration or otherwise), prepayment or conversion of a Eurodollar Loan on a date other than the last day of its Interest Period,

b.any failure (because of a failure to meet the conditions of Section 6 hereof or otherwise) by the Borrower to borrow or continue a Eurodollar Loan, or to convert a Base Rate Loan into a Eurodollar Loan, on the date specified in a notice given pursuant to Section 2.5(a) hereof or established pursuant to Section 2.5(c) hereof,

c.any failure by the Borrower to make any payment or prepayment of principal on any Eurodollar Loan when due (whether by acceleration or otherwise), or

d.any acceleration of the maturity of a Eurodollar Loan as a result of the occurrence of any Event of Default hereunder,

then, upon the demand of such Bank, the Borrower shall pay to such Bank such amount as will reimburse such Bank for such loss, cost or expense. If any Bank makes such a claim for compensation, it shall provide to the Borrower, with a copy to the Administrative Agent, a certificate executed by an officer of such Bank setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such certificate if reasonably calculated shall be prima facie evidence of the amount of such loss, cost or expense.

Section 2.12    Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Bank holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Bank in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the NYFRB Rate to the date of repayment, shall have been received by such Bank.

Section 2.13    Reserved.

Section 2.13    Defaulting Banks. Notwithstanding any provision of this Agreement to the contrary, if any Bank becomes a Defaulting Bank, then any amount payable to such Defaulting Bank hereunder (whether on account of principal, interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Bank pursuant to this Agreement) shall, in lieu of being distributed to such Defaulting Bank, subject to any applicable requirements of law, be applied (i) first, to the payment of any amounts owing by such Defaulting Bank to the Administrative Agent hereunder, and (ii) second, to such Defaulting Bank, or, in each case, as otherwise directed by a court of competent jurisdiction.

Notwithstanding anything set forth herein to the contrary, a Defaulting Bank shall not have any voting or consent rights under or with respect to any Credit Documents or constitute a “Bank” for any voting or consent rights under or with respect to any Credit Document, in any matter requiring the consent of Required Banks. Moreover, for the purposes of determining Required Banks and the Loans held, Defaulting Banks shall be excluded from the total Loans outstanding. For purposes of clarification, a Defaulting Bank shall not lose its right to vote with respect to matters set forth in clauses (i) and (ii) of Section 11.11 hereof.

Section 4.1    Place and Application of Payments. All payments of principal of and interest on the Loans, and of all other Obligations and other amounts payable by the Borrower under the Credit Documents, shall be made by the Borrower in U.S. Dollars to the Administrative Agent by no later than 2:00 p.m. (New York time) on the due date thereof at the principal office of the Administrative Agent pursuant to the payment instructions set forth on Part A of Schedule 4 hereto (or such other location in the, United States as the Administrative Agent may designate to the Borrower), for the benefit of the Person or Persons entitled thereto. Any payments received after such time shall be deemed to have been received by the Administrative Agent on the next Business Day. All such payments shall be made free and clear of, and without deduction for, any set-off, defense, counterclaim, levy, or any other deduction of any kind in immediately available funds at the place of payment. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest on Loans or applicable fees ratably to the Banks and like funds relating to the payment of any other amount payable to any Person to such Person, in each case to be applied in accordance with the terms of this Agreement.

The Borrower hereby represents and warrants to each Bank as to itself and, where the following representations and warranties apply to its Subsidiaries, as to each Subsidiary of the Borrower, as follows:

The unaudited balance sheet and income statements for the nine-month period ended September 30, 2020 have been prepared in accordance with generally accepted accounting principles applicable to interim financial statements applied on a basis consistent, except as otherwise noted therein, with the previous same fiscal period of the Borrower in the prior fiscal year (subject to normal year-end adjustments). Each of such financial statements fairly presents on a consolidated basis the financial condition of the Borrower and its Subsidiaries as of the dates thereof and the results of operations for the periods covered thereby. The Borrower and its Subsidiaries have no material contingent liabilities other than those disclosed in such financial statements referred to in this Section 5.4 or in comments or footnotes thereto, or in any report supplementary thereto, heretofore furnished to the Banks. Since December 31, 2019, there has been no event or series of events which has resulted in, or reasonably could be expected to result in, a Material Adverse Effect.

Section 5.5    No Litigation.    Except as disclosed on Schedule 5.5 hereto, there is no litigation or governmental proceeding pending, or to the knowledge of the Borrower, threatened, against the Borrower or any Subsidiary of the Borrower, in which there is a reasonable possibility

of an adverse decision which, if adversely determined, could (individually or in the aggregate) have a Material Adverse Effect.

Section 5.6    Taxes. The Borrower and its Subsidiaries have timely filed all United States federal tax returns, and all other foreign, state, local and other tax returns, required to be filed and have timely paid all taxes due from the Borrower and its Subsidiaries (whether or not pursuant to such returns or pursuant to any assessment received by the Borrower or any Subsidiary of the Borrower), except such taxes, if any, as are being contested in good faith and for which adequate reserves have been provided. No notices of tax liens have been filed, other than such notices in respect of any tax liens that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect, and no claims are being asserted concerning any such taxes, which liens or claims are material to the financial condition of the Borrower or any of its Subsidiaries (individually or in the aggregate). The charges, accruals and reserves on the books of the Borrower and its Subsidiaries for any taxes or other governmental charges are adequate and in conformance with GAAP.

Section 5.7    Approvals. No authorization, consent, approval, license, exemption, filing or registration with any court or governmental department, agency or instrumentality which have not already been obtained, nor any approval or consent of the stockholders of the Borrower or any Subsidiary of the Borrower or from any other Person, is necessary to the valid execution, delivery or performance by the Borrower or any Subsidiary of the Borrower of any Credit Document to which it is a party.

Section 5.8    ERISA.

Neither the Borrower nor any Subsidiary of the Borrower has any contingent liabilities for any post-retirement benefits under a Welfare Plan, and other than (i) liability for continuation coverage described in Part 6 of Title I of ERISA and Section 4980B of the Code or similar state statute and (ii) additional liabilities that could not (individually or in the aggregate) reasonably be expected to have a Material Adverse Effect. The Borrower is not an entity deemed to hold “plan assets” within the meaning of 29 C.F.R. § 2510.3-101, as modified by Section 3(42) of ERISA, of an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of Section 4975 of the Code) which is subject to Section 4975 of the Code. The assets of the Borrower are not subject to any law, rule or regulation which is substantially similar to the prohibited transaction provisions of Section 406 of ERISA or Section 4975 of the Code.

Section 5.10    Margin Stock; Use of Proceeds. Neither the Borrower nor any Subsidiary of the Borrower is engaged principally, or as one of its primary activities, in the business of extending

The proceeds of the Loans are to be used solely (i) to fund the Borrower’s and its Subsidiaries’ working capital needs and (ii) for general corporate purposes of the Borrower and its Subsidiaries. The Borrower will not use the proceeds of any Loan in a manner that violates any provision of Regulation U or X of the Board of Governors of the Federal Reserve System.

Section 5.11    Compliance with Laws.

The Borrower and each of its Subsidiaries is in compliance with all applicable laws, regulations, ordinances and orders of any governmental or judicial authorities except for any such law, regulation, ordinance or order which, the failure to comply therewith, could not reasonably expected to have a Material Adverse Effect.

Section 5.12    Ownership of Property; Liens. The Borrower and each Subsidiary of the Borrower has good title to or valid leasehold interests in all its Property necessary for the Borrower and its Subsidiaries to conduct its respective business, except for such defects in title as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

When any Event of Default described in subsections (f) or (g) of Section 8.1 hereof has occurred and is continuing, then all outstanding Loans, including both interest and principal thereon, and all other Obligations shall immediately become due and payable together with all other amounts payable under the Credit Documents without presentment, demand, protest or notice of any kind.

Section 8.4    Expenses. The Borrower agrees to pay to the Administrative Agent and each Bank, and any other holder of any Note outstanding hereunder, all reasonable and properly documented out-of-pocket costs and expenses incurred or paid by the Administrative Agent or such Bank or any such holder, including attorneys’ fees (including allocable fees of in house counsel) and court costs, in connection with (i) any amendment or waiver to the Credit Documents requested by the Borrower, (ii) any Default or Event of Default by the Borrower hereunder, or (iii) the enforcement of any of the Credit Documents.

SECTION 9.    CHANGE IN CIRCUMSTANCES.

Section 9.1    Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time after the date hereof any Change in Law makes it unlawful for any Bank to make or continue to maintain, make, fund, continue or convert Eurodollar Loans or to perform its obligations as contemplated hereby, such Bank shall promptly give notice thereof to the Borrower and such Bank’s obligations to make or maintain Eurodollar Loans under this Agreement shall be suspended until it is no longer unlawful for such Bank to make or maintain Eurodollar Loans. The Borrower shall prepay on demand the outstanding principal amount of any such affected Eurodollar Loans, together with all interest accrued thereon at a rate per annum equal to the interest rate applicable to such Loan; provided, however, subject to all of the terms and conditions of this Agreement, the Borrower may in the alternative elect to convert the principal amount of the affected Eurodollar Loans from such Bank into Base Rate Loans from such Bank, which Base Rate Loans shall not be made ratably by the Banks but only from such affected Bank.

Section 9.2    Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR.

(a)    Notwithstanding anything to the contrary in this Agreement or any other Credit Document, if the Administrative Agent determines (which determination shall be conclusive absent manifest error), or the Required Banks notify the Administrative Agent that the Required Banks have determined, that:

(i)    deposits of a type and maturity appropriate to match fund Borrowing of Eurodollar Loans are not available to such Banks in the relevant market, or

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

then the Administrative Agent shall suspend the availability of Borrowings of Eurodollar Loans and require any affected Borrowings of Eurodollar Loans to be repaid or converted to Borrowings of Base Rate Loans.

(b)    Benchmark Replacement.

(i)    Benchmark Transition Event; Early Opt-in Election. Notwithstanding anything to the contrary herein or in any other Credit Document, if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Credit Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Credit Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Credit Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth Business Day after the date notice of such Benchmark Replacement is provided by the Administrative Agent to the Banks without any amendment to, or further action or consent of any other party to, this Agreement or any other Credit Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Banks comprising the Required Banks.

(ii)    Term SOFR Transition Event. Notwithstanding anything to the contrary herein or in any other Credit Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Credit Document in respect of such Benchmark setting and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Credit Document; provided that, this clause (b)(ii) shall not be effective unless the Administrative Agent has delivered to the Banks and the Borrower a Term SOFR Notice. For the avoidance of doubt, the Administrative Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may do so in its sole discretion.

(iii)    Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Administrative Agent will have the

right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Credit Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Credit Document.

(iv)    Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Banks of (A) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes, (D) the removal or reinstatement of any tenor of a Benchmark pursuant to clause (v) below and (E) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Bank (or group of Banks) pursuant to this Section 9.2(b), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Credit Document, except, in each case, as expressly required pursuant to this Section 9.2(b).

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

(vi)    Benchmark Unavailability Period. Upon notice to the Borrower by the Administrative Agent in accordance with Section 11.8 of the commencement of a Benchmark Unavailability Period and until a Benchmark Replacement is determined in accordance with this Section 9.2(b), the Borrower may revoke any request for a Borrowing of Eurodollar Loans, or any request for the conversion or continuation of a Borrowing of Eurodollar Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a request for a Base Rate Borrowing or conversion to a Base Rate Borrowing. During any Benchmark Unavailability Period or at any time that a

tenor for the then-current Benchmark is not an Available Tenor, the component of the Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Base Rate.

Section 9.3    Increased Cost and Reduced Return.

a.If, on or after the date hereof, any Change in Law:

i.shall subject any Bank or the Administrative Agent to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

ii.shall impose, modify or deem applicable any reserve, special deposit, liquidity or similar requirement (including, without limitation, any compulsory loan requirement, insurance charge or other assessment or any other such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding with respect to any Eurodollar Loans any such requirement included in an applicable Eurodollar Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Lending Office) or shall impose on any Bank (or its Lending Office) or on the interbank market any other condition affecting its Eurodollar Loans, its Notes or its participation in any thereof or its obligation to make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to such Bank (or its Lending Office) or the Administrative Agent of making or maintaining any Loan or to reduce the amount of any sum received or receivable by such Bank (or its Lending Office) or the Administrative Agent under this Agreement or under its Notes with respect thereto, by an amount deemed by such Bank or the Administrative Agent to be material, then, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent) or the Administrative Agent, the Borrower shall be obligated to pay to such Bank or the Administrative Agent such additional amount or amounts as will compensate such Bank or the Administrative Agent for such increased cost or reduction. In the event any law, rule, regulation or interpretation described above is revoked, declared invalid or inapplicable or is otherwise rescinded, and as a result thereof a Bank or the Administrative Agent is determined to be entitled to a refund from the applicable authority for any amount or amounts which were paid or reimbursed by the Borrower to such Bank or the Administrative Agent hereunder, such Bank or the Administrative Agent shall refund such amount or amounts to the Borrower without interest.

b.If, after the date hereof, any Bank or the Administrative Agent shall have determined that any Change in Law regarding capital adequacy or liquidity requirements, or any change therein (including, without limitation, any revision in the Final Risk-Based Capital Guidelines of the Board of Governors of the Federal Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A) or of the Office of the Comptroller of the Currency (12 CFR Part 3, Appendix A), or in any other applicable capital or liquidity rules heretofore adopted and issued by any governmental authority), or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Lending Office) with any request or directive regarding capital adequacy or liquidity (whether or not having the force of law but, if not having the force of law, compliance with which is customary in the applicable jurisdiction) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Bank’s capital, or on

the capital of any corporation controlling such Bank, as a consequence of its obligations hereunder to a level below that which such Bank could have achieved but for such Change in Law (taking into consideration such Bank’s policies with respect to capital adequacy and liquidity) by an amount deemed by such Bank to be material, then from time to time, within fifteen (15) days after demand by such Bank (with a copy to the Administrative Agent), the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction.

c.Each Bank that determines to seek compensation under this Section 9.3 shall notify the Borrower and the Administrative Agent of the circumstances that entitle the Bank to such compensation pursuant to this Section 9.3 and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section 9.3 and setting forth the additional amount or amounts to be paid to it hereunder submitted to the Borrower and the Administrative Agent by such Bank in good faith shall be prima facie evidence of the amount of such compensation. In determining such amount, such Bank may use any reasonable averaging and attribution methods.

Section 9.4    Lending Offices. Each Bank may, at its option, elect to make its Loans hereunder at the branch, office or affiliate specified in its respective Administrative Questionnaire or in the assignment agreement which any assignee bank executes pursuant to Section 11.12 hereof (each a “Lending Office”) for each type of Loan available hereunder or at such other of its branches, offices or affiliates as it may from time to time elect and designate in a written notice to the Borrower and the Administrative Agent, so long as such election does not increase costs or other amounts payable by the Borrower to such Bank hereunder.

Section 9.5    Discretion of Bank as to Manner of Funding. Notwithstanding any other provision of this Agreement, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Bank had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the eurodollar interbank market having a maturity corresponding to such Loan’s Interest Period and bearing an interest rate equal to LIBOR for such Interest Period.

SECTION 10.    THE AGENT.

Section 10.1    Appointment and Authorization of Administrative Agent. Each Bank hereby appoints U.S. Bank National Association as the Administrative Agent under the Credit Documents and hereby authorizes the Administrative Agent to take such action as the Administrative Agent on its behalf and to exercise such powers under the Credit Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the other Credit Documents. The Administrative Agent is acting pursuant to a contractual relationship on an arm’s length basis and the duties of the Administrative Agent shall be mechanical and administrative in nature; the Administrative Agent shall not have by reason of this Agreement or any other Credit Document a fiduciary relationship in respect of any Bank, the holder of any Note or any other Person; and nothing in this Agreement or any other Credit Document, expressed or implied, is intended to or shall be so construed as to impose upon the Administrative Agent any obligations in respect of this Agreement or any other Credit Document except as expressly set forth herein or therein.

Section 10.2    Administrative Agent and its Affiliates. The Administrative Agent shall have the same rights and powers under this Agreement and the other Credit Documents as any other Bank and may exercise or refrain from exercising the same as though it were not the Administrative Agent, and the Administrative Agent and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Affiliate of the Borrower as if it were not the Administrative Agent under the Credit Documents.

Section 10.3    Action by Administrative Agent. If the Administrative Agent receives from the Borrower a written notice of an Event of Default pursuant to Section 7.6(d)(i) hereof, the Administrative Agent shall promptly give each of the Banks written notice thereof. The obligations of the Administrative Agent under the Credit Documents are only those expressly set forth therein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action hereunder with respect to any Default or Event of Default, except as expressly provided in Sections 8.2 and 8.3 hereof. In no event, however, shall the Administrative Agent be required to take any action in violation of applicable law or of any provision of any Credit Document, and the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder or under any other Credit Document unless it shall be first indemnified to its reasonable satisfaction by the Banks against any and all costs, expense, and liability which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall be entitled to assume that no Default or Event of Default exists unless notified to the contrary in writing by a Bank or the Borrower. In all cases in which this Agreement and the other Credit Documents do not require the Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in using its discretion in failing to take or in taking any action hereunder and thereunder.

Section 10.4    Consultation with Experts. The 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 10.5    Liability of Administrative Agent; Credit Decision. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or not taken by it in connection with the Credit Documents (i) with the consent or at the request of the Required Banks, or (ii) in the absence of its own gross negligence or willful misconduct (as proven by the final, non-appealable judgment of a court of competent jurisdiction). Neither the 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 this Agreement, any other Credit Document or any Credit Event; (ii) the performance or observance of any of the covenants or agreements of the Borrower or any other party contained herein or in any other Credit Document; (iii) the satisfaction of any condition specified in Section 6 hereof; or (iv) the validity, effectiveness, genuineness, enforceability, perfection, value, worth or collectibility hereof or of any other Credit Document or of any other documents or writing furnished in connection with any Credit Document; and the Administrative Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence. The Administrative Agent may execute any of its duties under any of the Credit Documents by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Banks, the Borrower, or any other Person for the default or misconduct of any such agents or attorneys-in-fact selected with reasonable care. The Administrative Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, other document or statement (whether written or oral) believed by it to be genuine or to be sent by the

proper party or parties. In particular and without limiting any of the foregoing, the Administrative Agent shall have no responsibility for confirming the accuracy of any Compliance Certificate or other document or instrument received by it under the Credit Documents. The Administrative Agent may treat the payee of any Note as the holder thereof until written notice of transfer shall have been filed with the Administrative Agent signed by such payee in form satisfactory to the Administrative Agent. Each Bank acknowledges that it has independently and without reliance on the Administrative Agent or any other Bank, and based upon such information, investigations and inquiries as it deems appropriate, made its own credit analysis and decision to extend credit to the Borrower in the manner set forth in the Credit Documents. It shall be the responsibility of each Bank to keep itself informed as to the creditworthiness of the Borrower and any other relevant Person, and the Administrative Agent shall have no liability to any Bank with respect thereto.

Section 10.6    Indemnity. The Banks shall ratably, in accordance with their respective Percentages, indemnify and hold the Administrative Agent, and its directors, officers, employees, agents and representatives harmless from and against any liabilities, losses, costs or expenses suffered or incurred by it under any Credit Document or in connection with the transactions contemplated thereby, regardless of when asserted or arising, except to the extent the Administrative Agent is promptly reimbursed for the same by the Borrower and except to the extent that any event giving rise to a claim was caused by the gross negligence or willful misconduct of the party seeking to be indemnified. The obligations of the Banks under this Section 10.6 shall survive termination of this Agreement.

Section 10.7    Resignation of Administrative Agent and Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and the Borrower. Upon any such resignation of the Administrative Agent, the Required Banks shall have the right to appoint a successor Administrative Agent with the consent of the Borrower. If no successor Administrative Agent shall have been so appointed by the Required Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be any Bank or any commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $200,000,000. Upon the acceptance of its appointment as the Administrative Agent hereunder, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent under the Credit Documents, and the retiring Administrative Agent shall be discharged from its duties and obligations thereunder; provided, if the Administrative Agent shall notify the Borrower and the Banks that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder, (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Bank directly, until such time as the Required Banks appoint a successor Administrative Agent as provided for above and (3) the agency fees shall be waived for the period from the effective date of the resignation of the resigning Administrative Agent until the effective date of the appointment of its successor. After any retiring Administrative Agent’s resignation hereunder as the Administrative Agent, the provisions of this Section 10 and all protective provisions of the other Credit Documents shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent.

Section 10.8    Certain ERISA Matters

SECTION 11    MISCELLANEOUS.

Section 11.1    Taxes.

a.Defined Terms. For purposes of this Section 11.1, 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 Credit 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) the applicable Administrative Agent or Bank 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 Administrative Agent or Bank, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Administrative Agent or Bank or required to be withheld or deducted from a payment to such Administrative Agent or Bank 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 Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Bank, shall be conclusive absent manifest error.

e.Indemnification by the Banks. Each Bank shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Bank (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 Bank’s failure to comply with the provisions of Section 11.10 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Bank, in each case, that are payable or paid by the Administrative Agent in connection with any Credit Document, and any reasonable expenses 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 Bank by the Administrative Agent shall be conclusive absent manifest error.  Each Bank hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Bank under any Credit Document or otherwise payable by the Administrative Agent to the Bank from any other source against any amount due to the Administrative Agent under this paragraph (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 11.1, 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 Banks. (i) Any Bank that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Credit 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 Bank, 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 Bank 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 11.1(g) (ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Bank’s reasonable judgment such completion, execution or submission would subject such Bank to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Bank; (ii) Without limiting the generality of the foregoing, (A) any Bank that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Bank becomes a Bank 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 Bank is exempt from U.S. Federal backup withholding tax; (B) any Foreign Bank 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 Bank becomes a Bank 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: (1)  in the case of a Foreign Bank 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 Credit Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, 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 Credit Document, IRS Form W-8BEN or IRS W-8BEN-E, as applicable, 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 Bank claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Bank is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable; or (4) to the extent a Foreign Bank is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Bank is a partnership and one or more direct or indirect partners of such Foreign Bank are claiming the portfolio interest exemption, such Foreign Bank may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner; (C) 

any Foreign Bank 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 Bank 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 (D) if a payment made to a Bank under any Credit Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Bank were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Bank 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 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 Bank has complied with such Bank’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.

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 11.1 (including by the payment of additional amounts pursuant to this Section 11.1), 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 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 paragraph (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 paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (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 paragraph 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.Survival. Each party’s obligations under this Section 11.1 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Bank, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Credit Document.

Section 11.2    No Waiver of Rights. No delay or failure on the part of the Administrative Agent or any Bank or on the part of the holder or holders of any Note in the exercise of any power or

right under any Credit Document shall operate as a waiver thereof, nor as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power or right, and the rights and remedies hereunder of the Administrative Agent, the Banks and the holder or holders of any Notes are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have.

Section 11.3    Non-Business Day. If any payment of principal or interest on any Loan or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such Loan or other Obligation bears for the period prior to maturity shall continue to accrue on such Obligation from the stated due date thereof to and including the next succeeding Business Day, on which the same shall be payable.

Section 11.4    Documentary Taxes. The Borrower agrees that it will pay any documentary, stamp or similar taxes payable in respect to any Credit Document, including interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any credit is then in use or available hereunder.

Section 11.5    Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any credit is in use or available hereunder.

Section 11.6    Survival of Indemnities. All indemnities and all other provisions relative to reimbursement to the Banks of amounts sufficient to protect the yield of the Banks with respect to the Loans, including, but not limited to, Section 2.11, Section 9.3 and Section 11.13 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations.

Section 11.7    Set-Off.

a.In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence of any Event of Default, each Bank and each subsequent holder of any Note is hereby authorized by the Borrower at any time or from time to time, without notice to the Borrower or to any other Person, any such notice being hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, Indebtedness evidenced by certificates of deposit, whether matured or unmatured, or otherwise fully matured, and in whatever currency denominated) and any other Indebtedness at any time held or owing by that Bank or that subsequent holder to or for the credit or the account of the Borrower, whether or not matured, against and on account of the obligations and liabilities of the Borrower to that Bank or that subsequent holder under the Credit Documents, including, but not limited to, all claims of any nature or description arising out of or connected with the Credit Documents, irrespective of whether or not (a) that Bank or that subsequent holder shall have made any demand hereunder or (b) the principal of or the interest on the Loans or Notes and other amounts due hereunder shall have become due and payable pursuant to Section 8 hereof and although said obligations and liabilities, or any of them, may be contingent or unmatured.

b.Each Bank agrees with each other Bank a party hereto that if such Bank shall receive and retain any payment, whether by set-off or application of deposit balances or otherwise, on any of the Loans in excess of its ratable share of payments on all such obligations then outstanding to the Banks, then such Bank shall purchase for cash at face value, but without recourse, ratably from each of the other Banks such amount of the Loans, or participations

therein, held by each such other Banks (or interest therein) as shall be necessary to cause such Bank to share such excess payment ratably with all the other Banks; provided, however, that if any such purchase is made by any Bank, and if such excess payment or part thereof is thereafter recovered from such purchasing Bank, the related purchases from the other Banks shall be rescinded ratably and the purchase price restored as to the portion of such excess payment so recovered, but without interest.

Section 11.8    Notices.

a.Except as otherwise specified herein, all notices under the Credit Documents shall be in writing (including facsimile or by using Electronic Systems) and shall be given to a party hereunder at its address or facsimile number set forth below or such other address or facsimile number as such party may hereafter specify by notice to the Administrative Agent and the Borrower, given by courier, by United States certified or registered mail, by other telecommunication device capable of creating a written record of such notice and its receipt or, to the extent permitted in Section 11.8(b) hereof, Electronic Systems.

Each such notice, request or other communication shall be effective (i) if given by facsimile, when such facsimile is transmitted to the facsimile number specified in this Section 11.8 or in the applicable Administrative Questionnaire and a confirmation of receipt of such facsimile has been received by the sender, (ii) if given by courier, when delivered, (iii) if given by mail, three (3) Business Days after such communication is deposited in the mail, registered with return receipt requested, addressed as aforesaid or (iv) if given by any other means, when delivered at the addresses specified or referred to in this Section 11.8; provided that any notice given pursuant to Section 2 hereof shall be effective only upon receipt during the recipient’s normal business hours.

b.Notices and other communications to the Banks hereunder may be delivered or furnished by using Electronic Systems pursuant to procedures approved by the Administrative Agent; provided that the foregoing shall not apply to notices pursuant to Article II unless otherwise agreed by the Administrative Agent and the applicable Bank. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

Section 11.9    Counterparts; Electronic Execution. This Agreement may be executed in any number of counterpart signature pages, and by the different parties on different counterparts, each of which when executed shall be deemed an original but all such counterparts taken together shall constitute one and the same instrument. Without notice to or consent of the Borrower, the Administrative Agent and each Bank may create electronic images of any Credit Documents and destroy paper originals of any such imaged documents. Such images have the same legal force and effect as the paper originals and are enforceable against the Borrower and any other parties thereto. If the Administrative Agent agrees, in its sole discretion, to accept delivery by telecopy or PDF of an executed counterpart of a signature page of any Credit Document or other document required to be delivered under the Credit Documents, such delivery will be valid and effective as delivery of an original manually executed counterpart of such document for all purposes. If the Administrative Agent agrees, in its sole discretion, to accept any electronic signatures of any Credit Document or other document required to be delivered under the Credit Documents, the words “execution,” “signed,” and “signature,” and words of like import, in or referring to any document so signed will deemed to include electronic signatures and/or the keeping of records in electronic form, which will be of the same legal effect, validity and enforceability as a manually executed signature and/or the use of a paper-based recordkeeping system, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. The Administrative Agent and each Bank may rely on any such electronic signatures without further inquiry.

Section 11.10    Successors and Assigns.

a.Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign any of its rights or obligations under any Credit Document unless such assignation occurs in connection with a merger or acquisition by the Borrower which is otherwise permitted under the terms of this Agreement and the appropriate Credit Documents, if applicable, and the Borrower obtains the prior written consent of all of the Banks, which consent shall be in form and substance satisfactory to the Administrative Agent. No Bank may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (g) 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 paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this Agreement.

b.Assignments by Banks. Any Bank may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of the Loans at the time owing to it); provided that

i.except in the case of an assignment of the entire remaining amount of the assigning Bank’s Loans at the time owing to it or in the case of an assignment to a Bank or an Affiliate of a Bank or an Approved Fund with respect to a Bank, the principal outstanding balance of the Loan of the assigning Bank 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 “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower, otherwise consents (each such consent not to be unreasonably withheld or delayed);

ii.each partial assignment shall be made as an assignment of a proportionate part of all the assigning Bank’s rights and obligations under this Agreement with respect to the Loan assigned;

iii.any assignment under this Section 11.10(b) must be approved by (i) the Administrative Agent (not to be unreasonably withheld) and (ii) unless the Person that is the proposed assignee is itself a Bank or an Affiliate of a Bank (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee) and/or an Event of Default has occurred and is continuing, the Borrower (not to be unreasonably withheld); 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 five (5) Business Days after having received notice thereof; and

iv.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,

and the Eligible Assignee, if it shall not be a Bank, shall deliver to the Administrative Agent an Administrative Questionnaire and any relevant tax forms.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible 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 Bank under this Agreement, and the assigning Bank 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 Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 9.3 and 9.4 hereof with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with paragraph (d) of this Section. The Borrower shall execute and deliver to the assignee a Note upon written request from such assignee. The assignor shall promptly return to the Borrower its Note if after giving effect to such assignment no Obligations are owing to such assignor.

c.Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Banks, and principal amounts of the Loans owing to, each Bank pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower at any reasonable time and from time to time upon reasonable prior notice.

d.Participations. Any Bank may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than an Ineligible Institution) (each, a “Participant”) in all or a portion of such Bank’s rights and/or obligations under this Agreement (including all or a portion of the Loans owing to it); provided that (i) such Bank’s obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Each Bank that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in such Bank’s Loans or other obligations under this Agreement (the “Participant Register”); provided that no Bank shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans or its other obligations under any this Agreement) except to the extent that such disclosure is necessary to establish that such Commitment, Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Bank shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement

notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

e.Any agreement or instrument pursuant to which a Bank sells such a participation shall provide that such Bank 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 Bank will not, without the consent of the Participant, agree to any amendment, modification or waiver of the type described in Section 11.11(i) hereof that affects such Participant. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 9.3 and 9.4 hereof to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.7(a) hereof as though it were a Bank, provided such Participant agrees to be subject to Section 11.7(b) hereof as though it were a Bank.

f.Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 9.3 and 9.4 hereof than the applicable Bank would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Bank if it were a Bank shall not be entitled to the benefits of Section 9.4 hereof unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 9.4 hereof as though it were a Bank.

g.Certain Pledges. Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central banking authority; provided that no such pledge or assignment shall release such Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Bank as a party hereto.

h.Certain Funding Arrangements. Notwithstanding anything to the contrary contained herein, any Bank (a “Granting Bank”) may grant to a special purpose funding vehicle which is an Affiliate of such Bank (a “SPC”), identified as such in writing from time to time by the Granting Bank to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Bank would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Bank shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Loan were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 11.10, any SPC may (i) with notice to, but

without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Bank or to any financial institutions (consented to by the Borrower and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section may not be amended without the written consent of the SPC.

Section 11.11    Amendments. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Borrower, (b) the Required Banks, and (c) if the rights or duties of the Administrative Agent are affected thereby, the Administrative Agent; provided that no amendment or waiver pursuant to this Section. 11.11 shall:

i.(A) increase, decrease or extend any Commitment of any Bank without the consent of such Bank or (B) reduce the amount of or, postpone any fixed date for payment of any principal of or interest on any Loan (including the Termination Date) or of any fee or other Obligation payable hereunder without the consent of each Bank; and

ii.unless signed by each Bank, change this Section 11.11, or the definition of Required Banks, or affect the number of Banks required to take any action under the Credit Documents or, with respect to the pro rata sharing of payments, amend Section 4.1 hereof or any other provision hereof relating to the pro rata sharing of payments.

Section 11.12    Headings. Section headings used in this Agreement are for reference only and shall not affect the construction of this Agreement.

Section 11.13    Legal Fees, Other Costs and Indemnification. The Borrower agrees to pay all reasonable and properly documented out-of-pocket costs and expenses of the Arranger and the Administrative Agent in connection with the preparation and negotiation of the Credit Documents (including past and future reasonable out-of-pocket expenses incurred by the Arranger and the Administrative Agent in connection with the syndication of the transaction), including without limitation, the reasonable fees, charges and disbursements of counsel to the Administrative Agent, in connection with the preparation and execution of the Credit Documents, and any amendment, waiver or consent related hereto, whether or not the transactions contemplated herein are consummated. The Borrower further agrees to indemnify each Bank, the Administrative Agent, and their respective Affiliates, directors, agents, advisors, officers and employees, against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor, whether or not the indemnified Person is a party thereto, and whether brought by a third-party or by the Borrower or any of its Affiliates) which any of them may incur or reasonably pay arising out of or relating to any Credit Document (including any relating to a misrepresentation by the Borrower under any Credit Document) or any of the transactions contemplated thereby or the direct or indirect application or proposed application of the proceeds of any Loan, other than to the extent arising from the gross negligence or willful misconduct of the party claiming indemnification as determined in a final, non-appealable judgment by a court of competent jurisdiction. The Borrower, upon demand by any of the Administrative Agent or a Bank at any time, shall reimburse the Administrative Agent or Bank for any reasonable legal or other expenses (including allocable fees and expenses of in-house counsel) incurred in connection with investigating or defending against any of the foregoing except if the same is directly due to the gross negligence or willful misconduct of the party to be indemnified as determined in a final, non-appealable judgment by a court of

competent jurisdiction, provided that with respect to legal costs and expenses incurred in connection with the enforcement of the rights of the Administrative Agent and the Banks under this Section 11.13, the Borrower shall only be obligated to pay the legal fees of the Administrative Agent and not of any other Bank. To the fullest extent permitted by applicable law, the Borrower shall not assert, and the Borrower hereby waives, any claim against the Administrative Agent, each Bank and each of their respective Affiliates, directors, agents, advisors, officers and employees, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Credit Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof.

Section 11.14    Entire Agreement. The Credit Documents constitute the entire understanding of the parties thereto with respect to the subject matter thereof and any prior or contemporaneous agreements, whether written or oral, with respect thereto are superseded thereby.

Section 11.15    Construction. The parties hereto acknowledge and agree that neither this Agreement nor the other Credit Documents shall be construed more favorably in favor of one than the other based upon which party drafted the same, it being acknowledged that all parties hereto contributed substantially to the negotiation of this Agreement and the other Credit Documents.

Section 11.16    Governing Law. This Agreement and the other Credit Documents, and the rights and duties of the parties hereto, shall be construed and determined in accordance with the internal laws of the State of New York.

Section 11.17    SUBMISSION TO JURISDICTION; WAIVER OF JURY TRIAL. THE BORROWER HEREBY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. THE BORROWER IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY.

Section 11.18    Replacement of Bank. Each Bank agrees that, upon the occurrence of any event set forth in Sections 9.1, 9.3 and 11.1 hereof, such Bank will use reasonable efforts to book and maintain its Loans through a different Lending Office or to transfer its Loans to an Affiliate with the objective of avoiding or minimizing the consequences of such event; provided that such booking or transfer is not otherwise disadvantageous to such Bank as determined by such Bank in its sole and absolute discretion. If any Bank has demanded to be paid additional amounts pursuant to Sections 9.1, 9.3 and 11.1 hereof, and the payment of such additional amounts are, and are likely to continue to be, more onerous in the reasonable judgment of the Borrower than with respect to the other Banks, then the Borrower shall have the right at any time when no Default or Event of Default shall have occurred and be continuing to seek one or more financial

institutions which are not Affiliates of the Borrower (each, a “Replacement Bank”) to purchase with the written consent of the Administrative Agent (which consent shall not be (x) required if such proposed Replacement Bank is already a Bank, or an Affiliate of a Bank, or (y) unreasonably delayed or withheld) the outstanding Loans of such Bank (the “Affected Bank”), and if the Borrower locates a Replacement Bank, the Affected Bank shall, upon

be deemed without any further action to have assigned and delegated all its rights and obligations under this Agreement and any other Credit Document to which it is a party (including its outstanding Loans) to the Replacement Bank (such assignment to be made without recourse, representation or warranty), and the Replacement Bank shall assume such rights and obligations, whereupon the Replacement Bank shall in accordance with Section 11.10 hereof become a party to each Credit Document to which the Affected Bank is a party and shall have the rights and obligations of a Bank thereunder and the Affected Bank shall be released from its obligations hereunder and each other Credit Document to the extent of such assignment and delegation.

Upon any such assignment and payment and compliance with the other provisions of Section 11.10 hereof, such replaced Bank shall no longer constitute a “Bank” for purposes hereof; provided, any rights of such replaced Bank to indemnification hereunder shall survive.

Section 11.19    Confidentiality. The Administrative Agent and the Banks shall hold all non-public information provided to them by the Borrower pursuant to or in connection with this Agreement in accordance with their customary procedures for handling confidential information of this nature, but may make disclosure to any of their agents, attorneys-in-fact, examiners, regulators, non-governmental self-regulatory authorities, Affiliates, outside auditors, counsel and other professional advisors in connection with this Agreement or any other Credit Document or as reasonably required by any potential bona fide transferee, participant or assignee, or in connection with the exercise of remedies under a Credit Document, or to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section 11.19), or to any nationally recognized rating agency that requires access to information about a Bank’s investment portfolio in connection with ratings issued with respect to such Bank, or as requested by any governmental agency, non-governmental self-regulatory authority or representative thereof or pursuant to legal

or regulatory process, or to any other party to this Agreement, or with the consent of the Borrower, or to the extent constituting information pertaining to this Agreement routinely provided by arrangers to data service providers, including league table providers, that serve the lending industry;; provided, however, that unless specifically prohibited by applicable law or court order, or in connection with any supervising examination, the Administrative Agent and each Bank shall use reasonable efforts to promptly notify the Borrower of any request by any governmental agency or representative thereof (other than any such request in connection with an examination of the financial condition of the Administrative Agent or such Bank by such governmental agency) for disclosure of any such non-public information and, where practicable, prior to disclosure of such information. Prior to any such disclosure pursuant to this Section 11.19, the Administrative Agent and each Bank shall require any such bona fide transferee, participant and assignee receiving a disclosure of non-public information to agree, for the benefit of the Borrower, in writing to be bound by this Section 11.19; and to require such Person to require any other Person to whom such Person discloses such non-public information to be similarly bound by this Section 11.19. Notwithstanding anything herein to the contrary, “confidential information” shall not include, and the Administrative Agent and each Bank may disclose to any and all persons, without limitation of any kind, (i) any information with respect to the U.S. Federal income tax treatment and U.S. Federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such Bank relating to such tax treatment and tax structure, (ii) information that has been publicly disclosed or has become public without breach of this Section 11.19 and (iii) information that now or hereafter becomes available to such Bank on a non-confidential basis from a source other than the Borrower.

Section 11.20    Rights and Liabilities of the Syndication Agent, Documentation Agent and Arranger. Neither the Syndication Agent, the Documentation Agent nor the Arranger has any special rights, powers, obligations, liabilities, responsibilities or duties under this Agreement as a result of acting in the capacity of Syndication Agent, Documentation Agent or Arranger, as applicable, other than those applicable to them in their capacity as Banks hereunder (if any).

Without limiting the foregoing, neither the Syndication Agent, the Documentation Agent nor the Arranger shall have or be deemed to have a fiduciary relationship with any Bank. Each Bank hereby makes the same acknowledgments and undertakings with respect to the Syndication Agent, the Documentation Agent and the Arranger as it makes with respect to the Administrative Agent and any directors, officers, agents and employees of the Administrative Agent in Section 10.5 hereof.

Section 11.21    Relationship. Neither the Administrative Agent nor any Bank has any fiduciary relationship or duty to the Borrower or any of its Subsidiaries arising out of or in connection with, and there is no agency, tenancy or joint venture relationship between the Administrative Agent or any Bank and the Borrower or any of its Subsidiaries by virtue of, any Credit Document or any transaction contemplated therein. To the fullest extent permitted by law, the Borrower hereby waives and releases any claims that it may have against each of the Banks and their Affiliates with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

The Borrower and each of its Subsidiaries understand that the Administrative Agent, each Bank and each of their respective affiliates (the Administrative Agent or such Bank, as the case may be, together with its affiliates, each referred to herein as a “Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research). Members of each Group and businesses within each Group generally act independently of each other, both for their own account and for the account of clients. Accordingly, there may be situations where parts of a Group and/or their clients either now have or may in the future have interests, or take actions, that may conflict with the interests of the Borrower or one of its Subsidiaries. For example, a Group may, in the ordinary course of business, engage in trading in financial products or undertake other investment businesses for their own account or on behalf of other clients, including without limitation, trading in or holding long, short or derivative positions in securities, loans or other financial products of the Borrower, its Subsidiaries or its affiliates or other entities connected with the Loans or the transactions contemplated hereby.

In recognition of the foregoing, the Borrower, for itself and on behalf of its Subsidiaries, agrees no Group is required to restrict its activities as a result of this Agreement and that each Group may undertake any business activity without further consultation with or notification to the Borrower or any of its Subsidiaries. Neither this Agreement nor the receipt by the Administrative Agent or any Bank of confidential information nor any other matter will give rise to any fiduciary, equitable or contractual duties (including but not limited to any duty of trust or confidence) that would prevent or restrict a Group from acting on behalf of other customers or for its own account. Furthermore, the Borrower, for itself and on behalf of its Subsidiaries, agrees that no Group and no member or business of a Group is under a duty to disclose to the Borrower or any of its Subsidiaries or use on behalf of the Borrower or any of its Subsidiaries any information whatsoever about or derived from those activities or to account for any revenue or profits obtained in connection with such activities. However, consistent with each Group’s long-standing policy to hold in confidence the affairs of its customers, no Group will use confidential information obtained from the Borrower or any of its Subsidiaries except in connection with its services to, and its relationship with, the Borrower and its Subsidiaries; provided, that each Group will be free to disclose information in any manner as required by law, regulation, regulatory authority or other applicable judicial or government order.

Section 11.22    Severability of Provisions. Any provision in this Agreement or any other Credit Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any

other jurisdiction, and to this end the provisions of this Agreement and the other Credit Documents are declared to be severable.

Section 11.23    Patriot Act Notice. Each Bank that is subject to the Patriot Act (as hereinafter defined) and the Administrative Agent (for itself and not on behalf of any Bank) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act (Title III of Pub. L. 107 56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Bank or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act.

Section 11.24    Acknowledgement and Consent to Bail-In of Affected Financial Institutions.

Notwithstanding anything to the contrary in any Credit Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any Affected Financial Institution arising under any Credit Document, to the extent such liability is unsecured, may be subject to the Write-Down and Conversion Powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

i.the application of any Write-Down and Conversion Powers by the applicable Resolution Authority to any such liabilities arising hereunder that may be payable to it by any party hereto that is an Affected Financial Institution; and

ii.the effects of any Bail-In Action on any such liability, including, if applicable:

a.a reduction in full or in part or cancellation of any such liability;

b.a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such Affected Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Credit Document; or

iii.the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of the applicable Resolution Authority.

In Witness Whereof, the parties hereto have caused this Agreement to be duly executed and delivered as of the day and year first above written.
