 Section
2.1 The Loans. 
 (a) Revolving Loans. The Lenders having Revolving Loan Commitments agree severally, and not jointly, upon the
terms and subject to the conditions of this Agreement, to lend to the Borrower from time to time prior to the Maturity Date amounts which do not exceed, (i) in the aggregate at any one time outstanding, the Revolving Loan Commitments and,
(ii) individually, such Lender’s Revolving Loan Commitment, in each case, as in effect from time to time; provided, however, that the Borrower may not request (and the Lenders shall have no obligation to make) an Advance
under this Section 2.1(a) in excess of the Available Revolving Loan Commitment on such date. 
 (b) Letters of Credit. Subject to
the terms and conditions of this Agreement, each Issuing Bank agrees to issue Letters of Credit for the account of the Borrower (and on behalf of the Subsidiaries) pursuant to Section 2.13 hereof in an aggregate amount not to exceed the
Available Letter of Credit Commitment determined immediately prior to giving effect to the issuance thereof. 
 Section 2.2 Manner of
Borrowing and Disbursement. 
 (a) Choice of Interest Rate, Etc. Any Advance hereunder shall, at the option of the Borrower, be
made as a Base Rate Advance or a LIBOR Advance; provided, however, that at such time as there shall have occurred and be continuing a Default hereunder, the Borrower shall not have the right to receive or Continue a LIBOR Advance or to
Convert a Base Rate Advance to a LIBOR Advance. Any notice given to the Administrative Agent in connection with a requested Advance hereunder shall be given to the Administrative Agent prior to 11:00 a.m. (New York, New York time) in order for such
Business Day to count toward the minimum number of Business Days required. 
 (b) Base Rate Advances. 
 (i) Advances. The Borrower shall give the Administrative Agent in the case of Base Rate Advances at least one (1) Business
Day’s irrevocable prior telephonic notice followed immediately by a Request for Advance; provided, however, that the Borrower’s failure to confirm any telephonic notice with a Request for 

  

 -17- 

 
Advance shall not invalidate any notice so given if acted upon by the Administrative Agent. Upon receipt of such notice from the Borrower, the Administrative
Agent shall promptly notify each Lender by telephone or telecopy of the contents thereof. 
 (ii) Conversions. The
Borrower may, without regard to the applicable Payment Date and upon at least three (3) Business Days’ irrevocable prior telephonic notice followed by a Request for Advance, Convert all or a portion of the principal of a Base Rate Advance
to a LIBOR Advance. On the date indicated by the Borrower, such Base Rate Advance shall be so Converted. The failure to give timely notice hereunder with respect to the Payment Date of any Base Rate Advance shall be considered a request for a Base
Rate Advance. 
 (c) LIBOR Advances. Upon request, the Administrative Agent, whose determination in absence of manifest error shall be
conclusive, shall determine the available LIBOR Bases and shall notify the Borrower of such LIBOR Bases to apply for the applicable LIBOR Advance. 
 (i) Advances. The Borrower shall give the Administrative Agent in the case of LIBOR Advances at least three (3) Business Days’ irrevocable prior telephonic notice followed immediately by a Request for
Advance; provided, however, that the Borrower’s failure to confirm any telephonic notice with a Request for Advance shall not invalidate any notice so given if acted upon by the Administrative Agent. Upon receipt of such notice
from the Borrower, the Administrative Agent shall promptly notify each Lender by telephone or telecopy of the contents thereof. 
 (ii) Conversions and Continuations. At least three (3) Business Days prior to the Payment Date for each LIBOR Advance, the Borrower shall give the Administrative Agent telephonic notice followed by written notice specifying
whether all or a portion of such LIBOR Advance (A) is to be Continued in whole or in part as one or more LIBOR Advances, (B) is to be Converted in whole or in part to a Base Rate Advance, or (C) is to be repaid. The failure to give
such notice shall preclude the Borrower from Continuing such Advance as a LIBOR Advance on its Payment Date and shall be considered a request to Convert such Advance to a Base Rate Advance. Upon such Payment Date such LIBOR Advance will, subject to
the provisions hereof, be so Continued, Converted or repaid, as applicable. 
 (d) Notification of Lenders. Upon receipt of
irrevocable prior telephonic notice in accordance with Section 2.2(b) or (c) hereof or a Request for Advance, or a notice of Conversion or Continuation from the Borrower with respect to any outstanding Advance prior to the Payment Date for
such Advance, the Administrative Agent shall promptly but no later than the close of business on the day of such notice notify each Lender having the applicable Commitment by telephone, followed promptly by written notice or telecopy, of the
contents thereof and the amount of such Lender’s portion of the Advance. Each Lender having the applicable Commitment shall, not later than 12:00 noon (New York, New York time) on the date of borrowing specified in such notice, make available
to the Administrative Agent at the Administrative Agent’s Office, or at such account as the Administrative Agent shall designate, the amount of its portion of any Advance that represents an additional borrowing hereunder in immediately
available funds. 
  

 -18- 

 (e) Disbursement. 
 (i) Prior to 2:00 p.m. (New York, New York time) on the date of an Advance hereunder, the Administrative Agent shall, subject to the
satisfaction of the conditions set forth in Article 3 hereof, disburse the amounts made available to the Administrative Agent by the Lenders in like funds by (A) transferring the amounts so made available by wire transfer pursuant to the
Borrower’s instructions, or (B) in the absence of such instructions, crediting the amounts so made available to the account of the Borrower maintained with the Administrative Agent. 
 (ii) Unless the Administrative Agent shall have received notice from a Lender having an applicable Commitment prior to 12:00 noon (New
York, New York time) on the date of any Advance that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Advance, the Administrative Agent may assume that such Lender has made or will make such
portion available to the Administrative Agent on the date of such Advance and the Administrative Agent may in its sole discretion and in reliance upon such assumption, make available to the requesting Borrower on such date a corresponding amount. If
and to the extent an applicable Lender does not make such ratable portion available to the Administrative Agent, such Lender agrees to repay to the Administrative Agent on demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the requesting Borrower until the date such amount is repaid to the Administrative Agent, at the Federal Funds Rate. 
 (iii) If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such
Lender’s portion of the applicable Advance for purposes of this Agreement. If such Lender does not repay such corresponding amount immediately upon the Administrative Agent’s demand therefor, the Administrative Agent shall notify the
Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative Agent, with interest at the Federal Funds Rate. The failure of any Lender to fund its portion of any Advance shall not relieve any other Lender of its
obligation, if any, hereunder to fund its respective portion of the Advance on the date of such borrowing, but no Lender shall be responsible for any such failure of any other Lender. 
 (iv) In the event that, at any time when there is no Default and each of the conditions in Section 3.2 hereof has been satisfied, a
Lender having an applicable Commitment for any reason fails or refuses to fund its portion of an Advance and such failure shall continue for a period in excess of thirty (30) days, then, until such time as such Lender has funded its portion of
such Advance (which late funding shall not absolve such Lender from any liability it may have to the Borrower), or all other Lenders have received payment in full from the Borrower (whether by repayment or prepayment) or otherwise of the principal
and interest due in respect of such Advance, such non-funding Lender shall not have the right (A) to vote regarding any issue on which voting is 

  

 -19- 

 
required or advisable under this Agreement or any other Loan Document, and such Lender’s portion of the applicable Loans and Commitments shall not be
counted as outstanding for purposes of determining “Majority Lenders” hereunder, and (B) to receive payments of principal, interest or fees from the Borrower, the Administrative Agent or the other Lenders in respect of its
portion of the applicable Loans until all applicable Loans of the other Lenders have been fully paid. 
 Section 2.3 Interest.

 (a) On Base Rate Advances. Interest on each Base Rate Advance shall be computed on the basis of a year of 365/366 days for the
actual number of days elapsed and shall be payable at the Base Rate Basis for such Advance, in arrears on the applicable Payment Date. Interest on Base Rate Advances then outstanding shall also be due and payable on the Maturity Date.

in arrears on every three (3) month anniversary of the beginning of such Interest Period. Interest on LIBOR Advances then outstanding shall also be due and payable on the Maturity Date. 
 (c) Interest if No Notice of Selection of Interest Rate Basis. If the Borrower fails to give the Administrative Agent timely notice of its
selection of a LIBOR Basis, or if for any reason a determination of a LIBOR Basis for any Advance is not timely concluded, the Base Rate Basis shall apply to such Advance. 
 (d) Interest Upon Event of Default. Immediately upon the occurrence of an Event of Default hereunder, the outstanding principal balance of the
Loans shall bear interest at the Default Rate. Such interest shall be payable on demand by the Majority Lenders and shall accrue until the earlier of (i) waiver or cure of the applicable Event of Default, (ii) agreement by the Majority
Lenders (or, if applicable to the underlying Event of Default, the Lenders) to rescind the charging of interest at the Default Rate or (iii) payment in full of the Obligations.

of the Loans and interest thereon. Each Lender which opens such a loan account shall debit such loan account for the principal amount of its portion of each Advance made by it and accrued interest thereon, and shall credit such loan account for each
payment on account of principal of or interest on its Loans. The records of a Lender with respect to the loan account maintained by it shall be prima facie evidence of its portion of the Loans and accrued interest thereon absent manifest error, but
the failure of any Lender to make any such notations or any error or mistake in such notations shall not affect the Borrower’s repayment obligations with respect to such Loans. 
 Section 2.8 Manner of Payment. 
 (a)
Each payment (including, without limitation, any prepayment) by the Borrower on account of the principal of or interest on the Loans, commitment fees and any other amount owed to the Lenders or the Administrative Agent or any of them under this
Agreement or the Notes shall be made not later than 1:00 p.m. (New York, New York time) on the date specified for payment under this Agreement to the Administrative Agent at the Administrative Agent’s Office, for the account of the Lenders or
the Administrative Agent, as the case may be, in lawful money of the United States of America in immediately available funds. Any payment received by the Administrative Agent after 1:00 p.m. (New York, New York time) shall be deemed received on the
next Business Day. Receipt by the Administrative Agent of any payment intended for any Lender or Lenders hereunder prior to 1:00 p.m. (New York, New York time) on any Business Day shall be deemed to constitute receipt by such Lender or Lenders on
such Business Day. In the case of a payment for the account of a Lender, the Administrative Agent will promptly, but no later than the close of business on the date such payment is deemed received, thereafter distribute the amount so received in
like funds to such Lender. If the Administrative Agent shall not have received any payment from the Borrower as 

  

 -24- 

 
and when due, the Administrative Agent will promptly notify the applicable Lenders accordingly. In the event that the Administrative Agent shall fail to make
distribution to any Lender as required under this Section 2.8, the Administrative Agent agrees to pay such Lender interest from the date such payment was due until paid at the Federal Funds Rate. 
 (b) The Borrower agrees to pay principal, interest, fees and all other amounts due hereunder or under the Notes without set-off or counterclaim or any
deduction whatsoever. 
 (c) Prior to the acceleration of the Loans under Section 8.2 hereof, if some but less than all amounts due from
the Borrower are received by the Administrative Agent with respect to the Obligations, the Administrative Agent shall distribute such amounts in the following order of priority, all on a pro rata basis to the Lenders: (i) to the payment on a
pro rata basis of any fees or expenses then due and payable to the Administrative Agent and the Issuing Banks, or any of them or expenses then due and payable to the Lenders; (ii) to the payment of interest then due and payable on the Loans on
a pro rata basis and of fees then due and payable to the Lenders on a pro rata basis; (iii) to the payment of all other amounts not otherwise referred to in this Section 2.8(c) then due and payable to the Administrative Agent, the Issuing
Banks and the Lenders, or any of them, hereunder or under the Notes or any other Loan Document; and (iv) to the payment of principal then due and payable on the Loans on a pro rata basis. 
 (d) Subject to any contrary provisions in the definition of Interest Period, if any payment under this Agreement or any of the other Loan Documents is
specified to be made on a day which is not a Business Day, it shall be made on the next Business Day, and such extension of time shall in such case be included in computing interest and fees, if any, in connection with such payment. 
 Section 2.9 Reimbursement. 
 (a)
Whenever any Lender shall sustain or incur any losses or reasonable out-of-pocket expenses in connection with (i) the failure by the Borrower to borrow, Continue or Convert any LIBOR Advance after having given notice of its intention to borrow,
Continue or Convert such Advance in accordance with Section 2.2 hereof (whether by reason of the Borrower’s election not to proceed or the non-fulfillment of any of the conditions set forth in Article 3 hereof), or (ii) the prepayment
other than on the applicable Payment Date (or failure to prepay after giving notice thereof) of any LIBOR Advance in whole or in part for any reason, the Borrower agrees to pay to such Lender, upon such Lender’s demand, an amount sufficient to
compensate such Lender for all such losses and out-of-pocket expenses. Such Lender’s good faith determination of the amount of such losses or out-of-pocket expenses, as set forth in writing and accompanied by calculations in reasonable detail
demonstrating the basis for its demand, shall be presumptively correct absent manifest error. 
 (b) Losses subject to reimbursement
hereunder shall include, without limiting the generality of the foregoing, lost margins, reasonable out-of-pocket expenses incurred by any Lender or any participant of such Lender permitted hereunder in connection with the re-employment 

  

 -25- 

 
of funds prepaid, paid, repaid, not borrowed, or not paid, as the case may be, and will be payable whether the Maturity Date is changed by virtue of an
amendment hereto (unless such amendment expressly waives such payment) or as a result of acceleration of the Loans. 
 Section 2.10 Pro
Rata Treatment. 
 (a) Advances. Each Advance under the Revolving Loan Commitments from the Lenders hereunder shall be made pro
rata on the basis of the applicable Commitment Ratios of the Lenders having a Revolving Loan Commitment. 
 (b) Payments. Except as
provided in Section 2.2(e) hereof and Article 10 hereof, each payment and prepayment of principal of, and interest on, the Loans shall be made to the Lenders pro rata on the basis of their respective unpaid principal amounts outstanding under
the applicable Loans immediately prior to such payment or prepayment. If any Lender shall obtain any payment (whether involuntary, through the exercise of any right of set-off, or otherwise) on account of the Loans in excess of its ratable share of
the Loans under its applicable Commitment Ratio, such Lender shall forthwith purchase from the other Lenders such participations in the portion of the applicable Loans made by them as shall be necessary to cause such purchasing Lender to share the
excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and each such other
Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.10(b) may, to the fullest extent
permitted by law, exercise all its rights of payment (including, without limitation, the right of set-off) with respect to such participation as fully as if such purchasing Lender were the direct creditor of the Borrower in the amount of such
participation. 
 (c) Commitment Reductions. Any reduction of the Revolving Loan Commitments required or permitted hereunder shall
reduce the Revolving Loan Commitment of each Lender having a Revolving Loan Commitment on a pro rata basis based on the Commitment Ratio of such Lender for the Revolving Loan Commitment. Any reduction of any Incremental Facility Commitment required
or permitted hereunder shall reduce the Incremental Facility Commitment of each Lender having such Incremental Facility Commitment on a pro rata basis based on the Commitment Ratio of such Lender for such Incremental Facility Commitment. 

Section 2.11 Capital Adequacy. If after the date hereof, the adoption of any Applicable Law regarding the capital adequacy of banks or bank
holding companies, or any change in Applicable Law (whether adopted before or after the Agreement Date) 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 such Lender (or the bank holding company of such Lender) with any directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central
bank or comparable agency, has or would have the effect of reducing the rate of return on any Lender’s capital as a consequence of its obligations hereunder with respect to the Loans and the Commitments to a level below that which it could have
achieved but for such adoption, change 

  

 -26- 

 
or compliance (taking into consideration such Lender’s policies with respect to capital adequacy immediately before such adoption, change or compliance
and assuming that such Lender’s (or the bank holding company of such Lender) capital was fully utilized prior to such adoption, change or compliance) by an amount reasonably deemed by such Lender to be material, then, upon demand by such
Lender, the Borrower shall promptly pay to such Lender such additional amounts as shall be sufficient to compensate such Lender (on an after-tax basis) for such reduced return which is reasonably allocable to this Agreement, together with interest
on such amount from the fourth (4th) Business Day after the date of demand or the Maturity Date, as applicable, until payment in full thereof at the Default Rate. A certificate of such Lender setting forth the amount to be paid to such Lender
by the Borrower as a result of any event referred to in this paragraph and supporting calculations in reasonable detail shall be presumptively correct absent manifest error. Notwithstanding any other provision of this Section 2.11, no Lender
shall demand compensation for any increased cost or reduction referred to above if it shall not at the time be the general policy or practice of such Lender to demand such compensation in similar circumstances under comparable provisions of other
credit agreements. 
 Section 2.12 Lender Tax Forms. 
 (a) On or prior to the Agreement Date and on or prior to the first Business Day of each calendar year thereafter, to the extent it may lawfully do so at such time, each Lender which is a Non-U.S. Person shall provide
each of the Administrative Agent and the Borrower (a) if such Lender is a “bank” under Section 881(c)(3)(A) of the Code, with a properly executed original of Internal Revenue Service Form W-8BEN or W-8ECI (or any successor form)
prescribed by the Internal Revenue Service or other documents satisfactory to the Borrower and the Administrative Agent, as the case may be, certifying (i) as to such Lender’s status as exempt from United States withholding taxes with
respect to all payments to be made to such Lender hereunder and under the Notes or (ii) that all payments to be made to such Lender hereunder and under the Notes are subject to such taxes at a rate reduced to zero by an applicable tax treaty,
or (b) if such Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and intends to claim exemption from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of “portfolio interest”, a Form W-8BEN, or any subsequent versions thereof or successors thereto (and, if such Lender delivers a Form W-8BEN, a certificate representing that such Lender is not a bank for purposes of
Section 881(c) of the Code, is not a ten-percent (10%) shareholder (within the meaning of Section 871(h)(3)(B) of the Code and is not a controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), properly completed and duly executed by such Lender, indicating that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States Federal income taxes as
permitted by the Code. Each such Lender agrees to provide the Administrative Agent and the Borrower with new forms prescribed by the Internal Revenue Service upon the expiration or obsolescence of any previously delivered form, or after the
occurrence of any event requiring a change in the most recent forms delivered by it to the Administrative Agent and the Borrower, in any case, to the extent it may lawfully do so at such time. 
 (b) On or prior to the Agreement Date, and to the extent permitted by applicable U.S. Federal law, on or prior to the first Business Day of each calendar
year thereafter, each Lender which is a U.S. Person shall provide the Administrative Agent and the Borrower a duly completed and executed copy of the Internal Revenue Service Form W-9 or successor form to the effect that it is a U.S. Person.

 Section 2.13 Letters of Credit. 
 (a) Subject to the terms and conditions hereof, the Issuing Banks, in reliance on the agreements of the Lenders set forth in Section 2.13(d) hereof,
hereby agree to issue one or more Letters of Credit up to an aggregate face amount equal to the Available Letter of Credit Commitment determined immediately prior to giving effect to the issuance thereof; provided, however, that the
Issuing Banks shall not issue any Letter of Credit (i) unless the conditions precedent to the issuance thereof set forth in Section 3.3 hereof have been satisfied, (ii) if any Default then exists or would be caused thereby,
(iii) if, after giving effect to such issuance, the Available Revolving Loan Commitment would be less than zero or (iv) within thirty (30) days preceding the Maturity Date; and provided further, however, that at no time
shall the aggregate amount of the Letter of Credit Obligations outstanding hereunder exceed $50,000,000.00. Each Letter of Credit shall (A) be payable at sight, (B) be denominated in United States dollars, (C) expire, (i) with
respect to Standby Letters of Credit, no later than the earlier to occur of (x) 360 days after its date of issuance (but may contain provisions for automatic renewal; provided that no Default or Event of Default exists on the
renewal date or would be caused by such renewal) and (y) the fifth Business Day preceding the Maturity Date, and (ii) with respect to Commercial Letters of Credit, no later than the earlier to occur of (x) 180 days after its date of
issuance (but may contain provisions for automatic renewal; provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal) and (y) the thirtieth day preceding the Maturity Date. Each Letter of
Credit shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 (or, if and when effective, Publication No. 600) and, to the extent not
inconsistent therewith, the laws of the State of New York. The Issuing Banks shall not at any time be obligated to issue, or cause to be issued, any Letter of Credit if such issuance would conflict with, or cause the Issuing Banks to exceed any
limits imposed by, any Applicable Law. If a Letter of Credit provides that it is automatically renewable unless notice is given by the applicable Issuing Bank that it will not be renewed, such Issuing Bank shall not be bound to give a notice of
non-renewal; provided, however, that during the continuance of a Default, the applicable Issuing Bank shall consult with the Lenders when determining whether to give a notice of non-renewal and shall give a notice of non-renewal if
directed to do so by Lenders having in the aggregate more than fifty percent (50%) of the Revolving Loan Commitment at least sixty-five (65) days prior to the then scheduled expiration date of such Letter of Credit. It is hereby agreed
that the Letters of Credit set forth on Schedule 2 attached hereto are Letters of Credit issued hereunder for all purposes hereunder notwithstanding anything herein that may be construed to the contrary. 
 (b) The Borrower may from time to time request (at its option and in its sole discretion) either Issuing Bank to issue Letters of Credit. The Borrower
shall execute and deliver to the Administrative Agent and applicable Issuing Bank a Request for Issuance of Letter of Credit for each Letter of Credit to be issued by such Issuing Bank not later than 12:00 noon (New York, New York time) on
the fifth (5th) Business Day preceding the date on which the requested Letter of Credit requested is to be issued, or such shorter notice as may be acceptable to such Issuing Bank and the Administrative Agent. Upon receipt of any such 

  

 -28- 

 
Request for Issuance of Letter of Credit, subject to satisfaction of all conditions precedent thereto as set forth in Section 3.3 hereof, the applicable
Issuing Bank shall process such Request for Issuance of Letter of Credit and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue
the Letter of Credit requested thereby. The applicable Issuing Bank shall furnish a copy of such Letter of Credit (or any amendment thereto or renewal or extension thereof) to the Borrower, the Administrative Agent and each of the Lenders following
the issuance thereof. The Borrower shall pay or reimburse the applicable Issuing Bank for normal and customary costs and expenses incurred by such Issuing Bank in issuing, effecting payment under, amending or otherwise administering the Letters of
Credit. 
 (c) At such time as the Administrative Agent shall be notified by the applicable Issuing Bank that the beneficiary under any
Letter of Credit has drawn on the same, the Administrative Agent shall promptly notify the Borrower and each Lender having a Revolving Loan Commitment, by telephonic notice, followed promptly by written notice, of the amount of the draw and, in the
case of each such Lender, such Lender’s portion of such draw amount as calculated in accordance with its respective Commitment Ratio under the Revolving Loan Commitment. 
 (d) The Borrower hereby agrees to immediately reimburse the applicable Issuing Bank for amounts paid by such Issuing Bank in respect of draws under a
Letter of Credit issued at the Borrower’s request. In order to facilitate such repayment, the Borrower hereby irrevocably requests the Lenders having a Revolving Loan Commitment, and such Lenders hereby severally agree, on the terms and
conditions of this Agreement (other than as provided in Article 2 hereof with respect to the amounts of, the timing of requests for, and the repayment of Advances hereunder and in Article 3 hereof with respect to conditions precedent to
Advances hereunder), with respect to any honoring of any draw under a Letter of Credit prior to the occurrence of an Event of Default under Section 8.1(f) or (g) hereof, to make an Advance (which Advance may be a LIBOR Advance if the
Borrower so requests in a timely manner or may be Converted to a LIBOR Advance as provided in the Loan Agreement) to the Borrower on each day on which the applicable Issuing Bank honors a draw made under any Letter of Credit and in the amount of
such draw, and to pay the proceeds of such Advance directly to such Issuing Bank to reimburse such Issuing Bank for the amount paid by it upon such draw. Each Lender having a Revolving Loan Commitment shall pay its share of such Advance by paying
its portion of such Advance to the Administrative Agent in accordance with Section 2.2(e) hereof and its respective Commitment Ratio under the Revolving Loan Commitments, without reduction for any set-off or counterclaim of any nature
whatsoever and regardless of whether any Default or Event of Default (other than with respect to an Event of Default under Section 8.1(f) or (g) hereof) then exists or would be caused thereby. If at any time that any Letters of Credit are
outstanding, any of the events described in clauses of Section 8.1(f) or (g) hereof shall have occurred and be continuing, then each Lender having a Revolving Loan Commitment shall, automatically upon the occurrence of any such event and
without any action on the part of the Issuing Banks, the Borrower, the Administrative Agent or such Lenders, be deemed to have purchased an undivided participation in the face amount of all Letters of Credit then outstanding in an amount equal to
such Lender’s respective Commitment Ratio under the Revolving Loan Commitments, and each Lender having a Revolving Loan Commitment shall, notwithstanding such Event of Default, upon a drawing being honored under any Letter of Credit,
immediately 

  

 -29- 

 
pay to the Administrative Agent for the account of the applicable Issuing Bank, in immediately available funds, the amount of such Lender’s
participation (and such Issuing Bank shall deliver to such Lender a loan participation certificate dated the date of the occurrence of such event and in the amount of such Lender’s respective Commitment Ratio under the Revolving Loan
Commitments). The disbursement of funds in connection with a draw under a Letter of Credit pursuant to this Section 2.13(d) shall be subject to the terms and conditions of Section 2.2(e) hereof. The obligation of each Lender having a
Revolving Loan Commitment to make payments to the Administrative Agent, for the account of the Issuing Banks, in accordance with this Section 2.13 shall be absolute and unconditional and no such Lender shall be relieved of its obligations to
make such payments by reason of non-compliance by any other Person with the terms of the Letter of Credit or for any other reason. The Administrative Agent shall promptly remit to the applicable Issuing Bank the amounts so received from the
other Lenders. Any overdue amounts payable by the Lenders having a Revolving Loan Commitment to the applicable Issuing Bank in respect of a draw under any Letter of Credit shall bear interest, payable on demand, at the rate on overnight Federal
funds transactions with members of the Federal Reserve System arranged by Federal funds brokers, as published for such day by the Federal Reserve Bank of New York. 
 (e) The Borrower agrees that any action taken or omitted to be taken by the Issuing Banks in connection with any Letter of Credit, except for such actions or omissions as shall constitute gross negligence or willful
misconduct on the part of the Issuing Banks, shall be binding on the Borrower as between the Borrower and the Issuing Banks, and shall not result in any liability of the Issuing Banks to the Borrower. The obligation of the Borrower to reimburse the
Lenders for Advances made to reimburse the Issuing Banks for draws under the Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances
whatsoever, including, without limitation, the following circumstances: 
 (i) any lack of validity or enforceability of any
Loan Document; 
 (ii) any amendment or waiver of or consent to any departure from any or all of the Loan Documents;

 (iii) any improper use which may be made of any Letter of Credit or any improper acts or omissions of any beneficiary or
transferee of any Letter of Credit in connection therewith; 
 (iv) the existence of any claim, set-off, defense or any right
which the Borrower may have at any time against any beneficiary or any transferee of any Letter of Credit (or Persons for whom any such beneficiary or any such transferee may be acting) or any Lender (other than the defense of payment to such Lender
in accordance with the terms of this Agreement) or any other Person, whether in connection with any Letter of Credit, any transaction contemplated by any Letter of Credit, this Agreement, any other Loan Document, or any unrelated transaction;

  

 -30- 

 (v) any statement or any other documents presented under any Letter of Credit proving to
be insufficient, forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; provided that the same shall not have resulted from gross negligence or willful misconduct of the
applicable Issuing Bank; 
 (vi) the insolvency of any Person issuing any documents in connection with any Letter of Credit;

 (vii) any breach of any agreement between the Borrower and any beneficiary or transferee of any Letter of Credit;
provided that the same shall not have resulted from the gross negligence or willful misconduct of the applicable Issuing Bank; 
 (viii) any irregularity in the transaction with respect to which any Letter of Credit is issued, including any fraud by the beneficiary or any transferee of such Letter of Credit; provided that the same shall
not have resulted from the gross negligence or willful misconduct of the applicable Issuing Bank; 
 (ix) any errors,
omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, wireless or otherwise, whether or not they are in code; provided that the same shall not have resulted from the gross negligence or
willful misconduct of the applicable Issuing Bank; 
 (x) any act, error, neglect or default, omission, insolvency or failure
of business of any of the correspondents of the applicable Issuing Bank; provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank; 
 (xi) any other circumstances arising from causes beyond the control of the applicable Issuing Bank; 
 (xii) payment by an Issuing Bank under any Letter of Credit against presentation of a sight draft or a certificate which does not comply
with the terms of such Letter of Credit; provided that the same shall not have resulted from gross negligence or willful misconduct of such Issuing Bank; and 
 (xiii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing; provided that the same shall
not have resulted from the result of gross negligence or willful misconduct of the applicable Issuing Bank or any other Lender. 
 (f) If any
change in Applicable Law, any change in the interpretation or administration thereof, or any change in compliance with Applicable Law by any Issuing Bank or any Lender having a Revolving Loan Commitment as a result of any official request or
directive of any governmental authority, central bank or comparable agency (whether or not having the force of law) shall (i) impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of
the Federal Reserve System), 

  

 -31- 

 
special deposit, capital adequacy, assessment or other requirements or conditions against Letters of Credit issued by any Issuing Bank or against
participations by any other Lender in the Letters of Credit or (ii) impose on any Issuing Bank or any other Lender any other condition regarding any Letter of Credit or any participation therein (other than with respect to Taxes, which shall be
governed exclusively by Section 10.3), and the result of any of the foregoing in the reasonable determination of such Issuing Bank or such Lender, as the case may be, is to increase the cost to such Issuing Bank or such Lender of issuing or
maintaining any Letter of Credit or purchasing or maintaining any participation therein, as the case may be, by an amount (which amount shall be reasonably determined) deemed by such Issuing Bank or such Lender to be material, and the designation of
a different lending office will not avoid the need for additional compensation (without creating other unreimbursed costs or disadvantage to such Lender), then, on request by such Issuing Bank or such Lender, the Borrower shall pay, within ten
(10) days after demand, such Issuing Bank or such Lender, as the case may be, such additional amount or amounts as such Issuing Bank or such Lender, as the case may be, so determines will compensate it on an after-tax basis for such increased
costs. A certificate of such Issuing Bank or such Lender setting forth the amount, and in reasonable detail the basis for such Issuing Bank or such Lender’s determination of such amount, to be paid to such Issuing Bank or such Lender by the
Borrower as a result of any event referred to in this paragraph shall, absent manifest error, be conclusive. 
 (g) Each Lender having a
Revolving Loan Commitment shall be responsible for its pro rata share (based on such Lender’s respective Commitment Ratio under the Revolving Loan Commitments) of any and all reasonable out-of-pocket costs, expenses (including reasonable legal
fees) and disbursements which may be incurred or made by any Issuing Bank in connection with the collection of any amounts due under, the administration of, or the presentation or enforcement of any rights conferred by any Letter of Credit, the
Borrower’s or any guarantor’s obligations to reimburse or otherwise. In the event the Borrower shall fail to pay such expenses of an Issuing Bank within ten (10) days after demand for payment by such Issuing Bank, each Lender having a
Revolving Loan Commitment shall thereupon pay to such Issuing Bank its pro rata share (based on such Lender’s respective Commitment Ratio under the Revolving Loan Commitments) of such expenses within five (5) days from the date of such
Issuing Bank’s notice to the Lenders having a Revolving Loan Commitment of the Borrower’s failure to pay; provided, however, that if the Borrower or any guarantor shall thereafter pay such expense, such Issuing Bank will
repay to each Lender having a Revolving Loan Commitment the amounts received from such Lender hereunder. 
 (h) The Borrower agrees that each
Advance by the Lenders having Revolving Loan Commitments to reimburse an Issuing Bank for draws under any Letter of Credit, shall, for all purposes hereunder, be deemed to be an Advance under the Revolving Loan Commitment to the Borrower and shall
be payable and bear interest in accordance with all other Revolving Loans to the Borrower. 
 (i) The Borrower will indemnify and hold
harmless the Administrative Agent, each Issuing Bank and each Lender and each of the foregoing Person’s respective employees, representatives, officers and directors from and against any and all claims, liabilities, obligations, losses (other
than loss of profits), damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable 

  

 -32- 

 
attorneys’ fees, but excluding Taxes, which shall be governed exclusively by Section 10.3) which may be imposed on, incurred by or asserted against
the Administrative Agent, any Issuing Bank or any such Lender in any way relating to or arising out of the issuance of a Letter of Credit, except that the Borrower shall not be liable to the Administrative Agent, any such Issuing Bank or any such
Lender for any portion of such claims, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, or disbursements resulting from the gross negligence or willful misconduct of the Person seeking indemnification
as determined by a non-appealable judicial order. This Section 2.13(i) shall survive termination of this Agreement. 
 (j) Within
two (2) Business Days after the issuance of a Letter of Credit, the applicable Issuing Bank shall send a written notice to the Administrative Agent setting forth the face amount, the expiration date and the name of the
beneficiary with respect to such Letter of Credit. Upon any cancellation or termination of a Letter of Credit prior to its stated expiration date, the applicable Issuing Bank shall notify the Administrative Agent of such termination or
cancellation in writing. 
 Section 2.14 Incremental Facility Advances. 
 (a) Subject to the terms and conditions of this Agreement, the Borrower may request an Incremental Facility Commitment (which may be a revolving credit or
term loan facility, but not a letter of credit facility) on any Business Day; provided, however, that (i) the Borrower may not request any Incremental Facility Commitment or an Incremental Facility Advance after the occurrence and
during the continuance of a Default or an Event of Default, including, without limitation, any Default or Event of Default that would result after giving effect to any Incremental Facility Advance and (ii) the aggregate amount of such
Incremental Facilities shall not exceed $500,000,000.00. No Incremental Facility Loans shall have a maturity date earlier than the Maturity Date. The decision of any Lender to provide an Incremental Facility Commitment to the Borrower shall be at
such Lender’s sole discretion and shall be made in writing. The Incremental Facility Commitment of a Lender providing an Incremental Facility Commitment shall, at the request of such Lender, be evidenced by an Incremental Facility Note. Persons
not then Lenders may be included as Lenders holding a portion of such Incremental Facility Commitment with the written approval of the Borrower and the Administrative Agent (such approval not to be unreasonably withheld, delayed, or conditioned).
The Incremental Facility Commitments shall be governed by this Agreement and the other Loan Documents and be on terms and conditions no more restrictive than those set forth herein and therein. The terms and conditions in this Section 2.14 may
be amended with the consent of the Majority Lenders and the Borrower, except to the extent that a specific Lender’s consent is otherwise required with respect to an issuance by such Lender of any Incremental Facility Commitment. 
 (b) Prior to the effectiveness of any Incremental Facility Commitment, the Borrower shall (i) deliver to the Administrative Agent and the Lenders a
Notice of Incremental Facility Commitment and (ii) provide revised projections to the Administrative Agent and the Lenders, which shall be in form and substance reasonably satisfactory to the Administrative Agent and which shall demonstrate the
Borrower’s ability to (x) timely repay its obligations hereunder prior to giving effect to such Incremental Facility Commitment and under such Incremental Facility Commitment and any Incremental Facility Advances thereunder and
(y) comply with the covenants contained in Sections 7.5, 7.6 and 7.7 hereof. 
  

 -33- 

 (c) Incremental Facility Advances (i) shall bear interest at the Base Rate Basis or the LIBOR Basis;
provided, however that the Applicable Margin with respect thereto shall be as agreed to by the Borrower and the Lenders making such Incremental Facility Advances and (ii) subject to Section 2.14(a) hereof, shall be repaid as
agreed to by the Borrower and the Lenders making such Incremental Facility Advances. 
 (d) Incremental Facility Advances (and Continuations
and Conversions thereof) shall be requested by the Borrower pursuant to a request (which shall be in substantially the form of a Request for Advance) delivered in the same manner as a Request for Advance, but (in the case of Incremental Facility
Advances) shall be funded pro rata only by those Lenders holding an Incremental Facility Commitment.

that the Borrower is the surviving Person, (ii) in connection with an Acquisition permitted hereunder effected by a merger in which the Borrower is the surviving Person, or (iii) a merger or consolidation (including, without limitation, in

acquisition (except to the extent such Indebtedness was incurred, or such 

  

 -47- 

 
Ownership Interests were issued, in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person or the property or assets of the Person so acquired, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings
of those instruments; provided that the encumbrances or restrictions contained in any such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings, taken as whole, are not materially
more restrictive than the encumbrances or restrictions contained in instruments as in effect on the date of acquisition, (iv) the foregoing shall not apply to restrictions and conditions on cash or other deposits or net worth imposed by
customers or lessors under contracts or leases entered into in the ordinary course of business, (v) the foregoing shall not apply to restrictions and conditions imposed on the transfer of copyrighted or patented materials or other intellectual

“issuer”, “guarantor”, “pledgor” or “lender” entities under CMBS Facilities permitted under Section 7.1(h) hereof or which arise in connection with any payment default regarding Indebtedness otherwise
permitted under Section 7.1 hereof.

with all other such property of the Borrower or any Material Subsidiary Group subject to other such process, exceeds in value $25,000,000.00 in the aggregate, and if, within thirty (30) days after the entry, issue or levy thereof, such

or Section 4975 of the Code; 
 (j) there shall occur (i) any acceleration of the maturity of any Indebtedness of the Borrower or

other amounts owed to the Lenders, the Issuing Banks and the Administrative Agent under this Agreement, the Notes and any other Loan Documents to be forthwith due and payable without presentment, demand, protest or other notice of any kind, all of
which are hereby expressly waived, anything in this Agreement, the Notes or any other Loan 

  

 -50- 

 
Document to the contrary notwithstanding, and the Revolving Loan Commitments (and, if applicable, the Incremental Facility Commitments) shall thereupon
forthwith terminate, and (ii) require the Borrower to, and the Borrower shall thereupon, deposit in an interest bearing account with the Administrative Agent, as cash collateral for the Obligations, an amount equal to the maximum amount

are expressly waived, anything in this Agreement or in the other Loan Documents to the contrary notwithstanding. 
 (c) Upon acceleration of
the Loans, as provided in Section 8.2(a) or (b) hereof, the Administrative Agent, the Issuing Banks and the Lenders shall have all of the post-default rights granted to them, or any of them, as applicable under the Loan Documents and under
Applicable Law. 
 (d) The rights and remedies of the Administrative Agent, the Issuing Banks and the Lenders hereunder shall be cumulative,
and not exclusive. 
 (e) In the event that the Administrative Agent establishes a cash collateral account as contemplated by this
Section 8.2, the Administrative Agent shall invest all funds in such account in such investments as the Administrative Agent, in its sole and absolute discretion, in good faith deems appropriate. The Borrower hereby acknowledges and agrees that
any interest earned on such funds shall be retained by the Administrative Agent as additional collateral for the Obligations. Upon satisfaction in full of all Obligations and the termination of the Commitments, the Administrative Agent shall pay any

 ARTICLE 9 - THE ADMINISTRATIVE AGENT 
 Section 9.1 Appointment and Authorization. Each Lender hereby appoints and authorizes, and hereby agrees that it will require any transferee of
any of its interest in its portion of the Loans and in its Note, if any, to appoint and authorize, the Administrative Agent to take such actions as its agent on its behalf and to exercise such powers hereunder and under the other Loan Documents as
are delegated by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. Neither the Administrative Agent, nor any of its respective directors, officers, employees or agents, shall be liable for any action taken
or omitted to be taken by it or them hereunder or in connection herewith, except for its or their own gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court of competent jurisdiction. 
 Section 9.2 Interest Holders. The Administrative Agent may treat each Lender, or the Person designated in the last notice filed with the
Administrative Agent, as the holder of all of the interests of such Lender in its portion of the Loans and in its Note, if any, until written notice of transfer, signed by such Lender (or the Person designated in the last notice filed with the
Administrative Agent) and by the Person designated in such written notice of transfer, in form and substance satisfactory to the Administrative Agent, shall have been filed with the Administrative Agent. 
 Section 9.3 Consultation with Counsel. The Administrative Agent may consult with Kilpatrick Stockton LLP, Atlanta, Georgia, special counsel to the
Administrative Agent, or with other legal counsel selected by it and shall not be liable for any action taken or suffered by it in good faith in consultation with the Majority Lenders and in reasonable reliance on such consultations. 
 Section 9.4 Documents. The Administrative Agent shall be under no duty to examine, inquire into, or pass upon the validity, effectiveness or
genuineness of this Agreement, any Note, any other Loan Document, or any instrument, document or communication furnished pursuant hereto or in connection herewith, and the Administrative Agent shall be entitled to assume that they are valid,
effective and genuine, have been signed or sent by the proper parties and are what they purport to be. 
  

 -52- 

 Section 9.5 Administrative Agent and Affiliates. With respect to the Commitments and the Loans,
the Administrative Agent shall have the same rights and powers hereunder as any other Lender, and the Administrative Agent and Affiliates of the Administrative Agent may accept deposits from, lend money to and generally engage in any kind of
business with the Borrower, any of its Subsidiaries or other Affiliates of, or Persons doing business with, the Borrower, any of its Subsidiaries or other Affiliates, as if they were not affiliated with the Administrative Agent and without any
obligation to account therefor. 
 Section 9.6 Responsibility of the Administrative Agent and Issuing Banks. The duties and
obligations of the Administrative Agent and the Issuing Banks under this Agreement are only those expressly set forth in this Agreement. The Administrative Agent shall be entitled to assume that no Default or Event of Default has occurred and is
continuing unless it has actual knowledge, or has been notified in writing by the Borrower, of such fact, or has been notified by a Lender in writing that such Lender considers that a Default or an Event of Default has occurred and is continuing,
and such Lender shall specify in detail the nature thereof in writing. The Administrative Agent and the Issuing Banks shall not be liable hereunder for any action taken or omitted to be taken except for its own respective gross negligence or willful
misconduct as determined by a final, non-appealable judicial order of a court of competent jurisdiction. The Administrative Agent shall provide each Lender and each Issuing Bank with copies of such documents received from the Borrower as such Lender
and such Issuing Bank may reasonably request. 
 Section 9.7 Action by the Administrative Agent and Issuing Banks. 
 (a) The Administrative Agent and the Issuing Banks shall be entitled to use its discretion with respect to exercising or refraining from exercising any
rights which may be vested in it by, and with respect to taking or refraining from taking any action or actions which it may be able to take under or in respect of, this Agreement, unless any of the Administrative Agent and the Issuing Banks shall
have been instructed by the Majority Lenders (or, where expressly required, all Lenders) to exercise or refrain from exercising such rights or to take or refrain from taking such action; provided, however, that the Administrative Agent
shall not exercise any rights under Section 8.2(a) hereof without the request of the Majority Lenders (or, where expressly required, all the Lenders), unless time is of the essence, in which case, such action can be taken at the discretion of
the Administrative Agent. The Administrative Agent shall incur no liability under or in respect of this Agreement with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment or which may seem to it to be
necessary or desirable in the circumstances, except for its gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court having jurisdiction over the subject matter. 
 (b) The Administrative Agent and the Issuing Banks shall not be liable to the Lenders or to any Lender or to the Borrower, any of its Subsidiaries or any
other obligor under any Loan Document in acting or refraining from acting under this Agreement or any other Loan Document in accordance with the instructions of the Majority Lenders (or, where expressly 

  

 -53- 

 
required, all of the Lenders), and any action taken or failure to act pursuant to such instructions shall be binding on all of the Lenders, except for its
gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court having jurisdiction over the subject matter. The Administrative Agent and the Issuing Banks shall not be obligated to take any action which is
contrary to law or which would in its reasonable opinion subject it to liability. 
 Section 9.8 Notice of Default or Event of
Default. In the event that the Administrative Agent, any Lender or any Issuing Bank shall acquire actual knowledge, or shall have been notified, of any Default or Event of Default, the Administrative Agent, such Lender or such Issuing Bank shall
promptly notify the Lenders (provided, however, that the failure to give such notice shall not result in any liability on the part of such Lender, such Issuing Bank or the Administrative Agent), and the Administrative Agent shall take
such action and assert such rights under this Agreement and the other Loan Documents as the Majority Lenders shall request in writing, and the Administrative Agent shall not be subject to any liability by reason of its acting pursuant to any such
request. If the Majority Lenders shall fail to request the Administrative Agent to take action or to assert rights under this Agreement or any other Loan Documents in respect of any Default or Event of Default within ten (10) days after their
receipt of the notice of any Default or Event of Default from the Administrative Agent, any Lender or any Issuing Bank, or shall request inconsistent action with respect to such Default or Event of Default, the Administrative Agent may, but shall
not be required to, take such action and assert such rights (other than rights under Article 8 hereof) as it deems in its discretion to be advisable for the protection of the Lenders, except that, if the Majority Lenders have instructed the
Administrative Agent not to take such action or assert such right, in no event shall the Administrative Agent act contrary to such instructions, unless time is of the essence, in which case, the Administrative Agent may act in accordance with its
reasonable discretion. 
 Section 9.9 Responsibility Disclaimed. The Administrative Agent shall not be under any liability or
responsibility whatsoever as the Administrative Agent: 
 (a) to the Borrower or any other Person as a consequence of any failure or delay in
performance by, or any breach by, any Lender or Lenders of any of its or their obligations under this Agreement; 
 (b) to any Lender or
Lenders as a consequence of any failure or delay in performance by, or any breach by, (i) the Borrower of any of its obligations under this Agreement or the Notes or any other Loan Document, or (ii) any Subsidiary of the Borrower or any
other obligor under any other Loan Document; 
 (c) to any Lender or Lenders, for any statements, representations or warranties in this
Agreement, or any other document contemplated by this Agreement or any information provided pursuant to this Agreement, any other Loan Document, or any other document contemplated by this Agreement, or for the validity, effectiveness, enforceability
or sufficiency of this Agreement, the Notes, any other Loan Document, or any other document contemplated by this Agreement; or 
  

 -54- 

 (d) to any Person for any act or omission other than that arising from gross negligence or willful
misconduct of the Administrative Agent as determined by a final, non-appealable judicial order of a court of competent jurisdiction. 
 Section 9.10 Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Borrower) pro rata according to their respective Commitment Ratios, from and against any and all liabilities,
obligations, losses (other than the loss of principal, interest and fees hereunder in the event of a bankruptcy or out-of-court ‘work-out’ of the Loans), damages, penalties, actions, judgments, suits, or reasonable out-of-pocket costs,
expenses (including, without limitation, fees and disbursements of experts, agents, consultants and counsel), or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent in any
way relating to or arising out of this Agreement, any other Loan Document, or any other document contemplated by this Agreement or any other Loan Document or any action taken or omitted by the Administrative Agent under this Agreement, any other
Loan Document, or any other document contemplated by this Agreement, except that no Lender shall be liable to the Administrative Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, or
reasonable out-of-pocket costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Administrative Agent as determined by a final, non-appealable judicial order of a court having jurisdiction over the subject
matter. 
 Section 9.11 Credit Decision. Each Lender confirms that: 
 (a) in making its decision to enter into this Agreement and to make its portion of the Loans it has independently taken whatever steps it considers
necessary to evaluate the financial condition and affairs of the Borrower and that it has made an independent credit judgment, and that it has not relied upon the Administrative Agent or information provided by the Administrative Agent (other than
information provided to the Administrative Agent by the Borrower and forwarded by the Administrative Agent to the Lenders); and 
 (b) so
long as any portion of the Loans remains outstanding or such Lender has an obligation to make its portion of Advances hereunder, it will continue to make its own independent evaluation of the financial condition and affairs of the Borrower.

 Section 9.12 Successor Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as
provided below, the Administrative Agent may resign at any time by giving written notice thereof to the Lenders, the Issuing Banks and the Borrower and may be removed at any time for cause by the Majority Lenders. Upon any such resignation or
removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent which appointment shall, prior to a Default, be subject to the consent of the Borrower, acting reasonably. If (a) no successor Administrative Agent
shall have been so appointed by the Majority Lenders or (b) appointed, no successor Administrative Agent shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gave notice of resignation or the
Majority Lenders removed the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor Administrative Agent which shall be any Lender or a commercial bank organized
under the laws of the United States of America or any political subdivision thereof

which has combined capital and reserves in excess of $250,000,000.00 and which shall be reasonably acceptable to the Borrower. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges, duties and obligations of the retiring
Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents. After any retiring Administrative Agent’s resignation or removal hereunder as
Administrative Agent the provisions of this Article shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent. In the event that the Administrative Agent or
any of its respective Affiliates ceases to be a Lender hereunder, such Person shall resign its agency hereunder. 
 Section 9.13
Delegation of Duties. The Administrative Agent may execute any of its duties under the Loan Documents by or through agents or attorneys selected by it using reasonable care, and shall be entitled to advice of counsel concerning all matters
pertaining to such duties. 
 Section 9.14 No Responsibilities of the Agents. Notwithstanding any provision to the contrary contained
elsewhere herein or in any other Loan Document, the Syndication Agent and the Co-Arrangers (as set forth on the cover page hereof) shall not have any duties or responsibilities, nor shall the Syndication Agent or any of the Co-Arrangers have or be
deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist
against the Syndication Agent or any of the Co-Arrangers. 
 ARTICLE 10 - CHANGES IN CIRCUMSTANCES 
 AFFECTING LIBOR ADVANCES AND INCREASED COSTS 
 Section 10.1 LIBOR Basis Determination Inadequate or Unfair. If with respect to any proposed LIBOR Advance for any Interest Period, the Administrative Agent determines after consultation with the Lenders that adequate and fair means
do not exist for determining the LIBOR Basis, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such
situation no longer exist, the obligations of any affected Lender to make its portion of such LIBOR Advances shall be suspended and each affected Lender shall make its portion of such LIBOR Advance as a Base Rate Advance. 
 Section 10.2 Illegality. If, after the date hereof, the adoption of any Applicable Law, or any change in any Applicable Law (whether adopted
before or after the Agreement Date), or any change in interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender
with any directive (whether or not having the force of law) of any such authority, central bank or comparable agency, shall make it unlawful or impossible for any Lender to make, maintain or fund its portion of LIBOR Advances, such Lender shall so
notify the Administrative Agent, and the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrower. Before giving any notice to the Administrative Agent pursuant to this Section 

  

 -56- 

 
10.2, such Lender shall designate a different lending office if such designation will avoid the need for giving such notice and will not, in the sole
reasonable judgment of such Lender, be otherwise materially disadvantageous to such Lender. Upon receipt of such notice, notwithstanding anything contained in Article 2 hereof, the Borrower shall repay in full the then outstanding principal amount
of such Lender’s portion of each affected LIBOR Advance, together with accrued interest thereon, on either (a) the last day of the then current Interest Period applicable to such affected LIBOR Advances if such Lender may lawfully continue
to maintain and fund its portion of such LIBOR Advance to such day or (b) immediately if such Lender may not lawfully continue to fund and maintain its portion of such affected LIBOR Advances to such day. Concurrently with repaying such portion
of each affected LIBOR Advance, the Borrower may borrow a Base Rate Advance from such Lender, whether or not it would have been entitled to effect such borrowing, and such Lender shall make such Advance, if so requested, in an amount such that the
outstanding principal amount of the Advance shall equal the outstanding principal amount of the affected LIBOR Advance of such Lender immediately prior to such repayment. 
 Section 10.3 Increased Costs and Additional Amounts. 
 (a) If after the date hereof, the adoption of
any Applicable Law, or any change in any Applicable Law (whether adopted before or after the Agreement Date), or any interpretation or change in interpretation or administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof or compliance by any Lender with any directive issued after the Agreement Date (whether or not having the force of law) of any such authority, central bank or comparable agency:

 (i) shall subject any Lender to any Tax with respect to its obligation to make its portion of LIBOR Advances, or its
portion of other Advances, or shall change the basis of taxation of payments to any Lender of the principal of or interest on its portion of LIBOR Advances or in respect of any other amounts due under this Agreement, or its obligation to make its
portion of Advances (except for changes with respect to Taxes imposed on the revenues or net income of such Lender, and except for any Taxes referred to in Section 10.3(b) hereof); or 
 (ii) shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the
Federal Reserve System, but excluding any included in an applicable Eurodollar Reserve Percentage), special deposit, capital adequacy, assessment or other requirement or condition against assets of, deposits with or for the account of, or
commitments or credit extended by, any Lender or shall impose on any Lender or the London interbank borrowing market any other condition affecting its obligation to make its portion of such LIBOR Advances or its portion of existing Advances;

 and the result of any of the foregoing is to increase the cost to such Lender of making or maintaining any of its portion of LIBOR Advances, or to reduce
the amount of any sum received or receivable by such Lender under this Agreement or under its Note, if any, with respect thereto, then, within ten (10) days after demand by such Lender, the Borrower agrees to pay to such Lender such additional
amount or amounts as will compensate such Lender on an after-tax basis for such increased costs. 
  

 -57- 

 (b) All payments made by the Borrower under this Agreement shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future income or other similar taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”), now or hereafter imposed, levied, collected, withheld
or assessed by any governmental authority, excluding any Taxes imposed on a Lender by reason of any connection between the Lender and the taxing jurisdiction other than executing, delivering, performing or enforcing this Agreement and receiving
payments hereunder. If any such non-excluded Taxes (collectively, the “Non-Excluded Taxes”) are required to be withheld or deducted from any such payment, the Borrower shall pay such additional amounts as may be necessary to ensure
that the net amount actually received by a Lender after such withholding or deduction is equal to the amount that the Lender would have received had no such withholding or deduction been required; provided, however, that the Borrower
shall not be required to increase any such amounts payable to any Lender if such Lender may lawfully comply with the requirements of Section 2.12 hereof and fails to do so. Whenever any Non-Excluded Taxes are payable by the Borrower, as
promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment
thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fail to remit to the Administrative Agent the required receipts or other documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as result of any such failure. The Borrower shall make any payments required pursuant to the
immediately preceding sentence within thirty (30) days after receipt of written demand therefor from the Administrative Agent or any Lender, as the case may be. The agreements set forth in this Section 10.3 shall survive the termination of
this Agreement and the payment of the Obligations. Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation
pursuant to this Section 10.3 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 reasonable judgment of such Lender made in good faith, be
otherwise disadvantageous to such Lender. Notwithstanding any provision herein to the contrary, the Borrower shall have no obligation to pay to any Lender any amount which the Borrower is liable to withhold due to the failure of such Lender to file
any statement of exemption required under the Code in order to permit the Borrower to make payments to such Lender without such withholding. 
 (c) Any Lender claiming compensation under this Section 10.3 shall provide the Borrower with a written certificate setting forth the additional amount or amounts to be paid to it hereunder and calculations therefor in reasonable
detail. Such certificate shall be presumptively correct absent manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. If any Lender demands compensation under this Section 10.3, the
Borrower may at any time, upon at least five (5) Business Days’ prior notice to such Lender, prepay in full such Lender’s portion of the then outstanding LIBOR Advances, together with accrued interest and fees thereon to the date of
prepayment, along with any reimbursement required under Section 2.9 hereof and this Section 10.3. Concurrently with 

  

 -58- 

 
prepaying such portion of LIBOR Advances the Borrower may, whether or not then entitled to make such borrowing, borrow a Base Rate Advance, or a LIBOR
Advance not so affected, from such Lender, and such Lender shall, if so requested, make such Advance in an amount such that the outstanding principal amount of such Advance shall equal the outstanding principal amount of the affected LIBOR Advance
of such Lender immediately prior to such prepayment. 
 (d) The Borrower shall pay any present or future stamp, transfer or documentary Taxes
or any other excise or property Taxes that may be imposed in connection with the execution, delivery or registration of this Agreement or any other Loan Documents. 
 Section 10.4 Effect On Other Advances. If notice has been given pursuant to Section 10.1, 10.2 or 10.3 hereof suspending the obligation of any Lender to make its portion of any type of LIBOR Advance, or
requiring such Lender’s portion of LIBOR Advances to be repaid or prepaid, then, unless and until such Lender notifies the Borrower that the circumstances giving rise to such repayment no longer apply, all amounts which would otherwise be made
by such Lender as its portion of LIBOR Advances shall be instead as Base Rate Advances, unless otherwise notified by the Borrower. 
 Section
10.5 Claims for Increased Costs and Taxes; Replacement Lenders. In the event that any Lender shall decline to make LIBOR Advances pursuant to Sections 10.1 and 10.2 hereof or shall have notified the Borrower that it is entitled to claim
compensation pursuant to Section 10.3, 2.8, 2.9 or 2.11 hereof or is unable to complete the form required or is subject to withholding on account of any Tax (each such lender being an “Affected Lender”), the Borrower at its own
cost and expense may designate a replacement lender (a “Replacement Lender”) to assume the Revolving Loan Commitments and/or Incremental Facility Commitments and the obligations of any such Affected Lender hereunder, and to purchase
the outstanding Loans of such Affected Lender and such Affected Lender’s rights hereunder and with respect thereto, and within ten (10) Business Days of such designation the Affected Lender shall (a) sell to such Replacement Lender,
without recourse upon, warranty by or expense to such Affected Lender, by way of an Assignment and Assumption Agreement substantially in the form of Exhibit H attached hereto, for a purchase price equal to (unless such Lender agrees to a
lesser amount) the outstanding principal amount of the Loans of such Affected Lender, plus all interest accrued and unpaid thereon and all other amounts owing to such Affected Lender hereunder, including without limitation, payment by the Borrower
of any amount which would be payable to such Affected Lender pursuant to Section 2.9 hereof (provided that the administrative fee set forth in Section 11.4(c)(iii) shall not apply to an assignment described in this clause (a)), and
(b) assign the Revolving Loan Commitments and/or Incremental Facility Commitments of such Affected Lender and upon such assumption and purchase by the Replacement Lender, such Replacement Lender shall be deemed to be a “Lender”
for purposes of this Agreement and such Affected Lender shall cease to be a “Lender” for purposes of this Agreement and shall no longer have any obligations or rights hereunder (other than any obligations or rights which according
to this Agreement shall survive the termination of the Revolving Loan Commitments and/or Incremental Facility Commitments).

 (iii) If to the Lenders, to them at the addresses set
forth beside their names as set forth in Schedule 1 attached hereto. 
 The failure to provide copies shall not affect the validity of the notice
given to the primary recipient. 
 (b) Any party hereto may change the address to which notices shall be directed under this
Section 11.1 by giving ten (10) days’ written notice of such change to the other parties. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been
given on the date of receipt. 
 (c) For purposes of this Agreement, delivery may also be made by the posting of any required documents,
reports, certificates, or other information to the Intralinks system or any other electronic distribution system to which all Lenders have access and provided that all Lenders are notified in writing (or electronically) that such posting has

other electronic platform, is provided “as is” and “as available” and (iii) neither the Administrative Agent nor any of its Affiliates warrants the accuracy, adequacy or completeness of Intralinks, or any other electronic
platform. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom from viruses or other code defects,
is made by the Administrative Agent or any of its Affiliates in connection with Intralinks or any other electronic platform.

 (d) All notices and other communications given to any party hereto in accordance with the provisions of
this Agreement shall be deemed to have been given on (i) the date of receipt if delivered by hand or overnight courier service or sent by telecopy or electronic mail, (ii) the date of posting if made through Intralinks or any other
electronic platform, or (iii) on the date five (5) Business Days after dispatch by registered mail if mailed, or an earlier date if sooner received, in each case delivered, sent or mailed (properly addressed) to such party as provided in
this Section 11.1. 
 Section 11.2 Expenses. The Borrower will promptly pay, or reimburse: 
 (a) all reasonable out-of-pocket expenses of the Administrative Agent in connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Loan Documents, and the transactions contemplated hereunder and thereunder any amendments, waivers and consents associated therewith, including, without limitation, the reasonable fees and disbursements of Kilpatrick Stockton
LLP, Atlanta, Georgia, special counsel for the Administrative Agent; and 
 (b) all reasonable out-of-pocket costs and expenses of the
Administrative Agent, the Lenders, the Issuing Banks and the Syndication Agent of enforcement under this Agreement or the other Loan Documents and all reasonable out-of-pocket costs and expenses of collection if an Event of Default occurs in the
payment of the Notes, which in each case shall include, without limitation, reasonable fees and out-of-pocket expenses of counsel for the Administrative Agent, each of the Lenders, each of the Issuing Banks and the Syndication Agent. 
 Section 11.3 Waivers. The rights and remedies of the Administrative Agent, the Lenders and the Issuing Banks under this Agreement and the other
Loan Documents shall be cumulative and not exclusive of any rights or remedies which they would otherwise have. No failure or delay by the Administrative Agent, the Majority Lenders, the Lenders and the Issuing Banks, or any of them, in exercising
any right, shall operate as a waiver of such right. No waiver of any provision of this Agreement or consent to any departure by the Borrower or any of its Subsidiaries therefrom shall in any event be effective unless the same shall be permitted by
Section 11.11, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall
not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time. 
 Section 11.4 Assignment and Participation. 
 (a) The Borrower may not assign or transfer any of its
rights or obligations hereunder, under the Notes or under any other Loan Document without the prior written consent of each Lender and each Issuing Bank. 
 (b) Each Lender may at any time sell assignments or participations of up to one hundred percent (100%) of its interest hereunder to (i) one (1) or more Affiliates of such Lender (provided,
however, that if such Affiliate is not a financial institution, such Lender 

  

 -62- 

 
shall be obligated to repurchase such assignment if such Affiliate is unable to honor its obligations hereunder), (ii) any Federal Reserve Bank as
collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank (provided, however, that no such assignment shall relieve such Lender
from its obligations hereunder) or (iii) any Person who is a Lender on such date. Notwithstanding the foregoing, no assignee of, or participant with respect to, any interest sold hereunder pursuant to this Section 11.4(b) shall be entitled
to receive any greater payment under Section 10.3 than the applicable Lender would have been entitled to receive with respect to the interest sold. 
 (c) Each Lender may at any time sell assignments or participations to one or more Persons pursuant to which each Lender may assign or participate its interest under this Agreement and the other Loan Documents,
including its interest in any particular Advance or portion thereof; provided, however, that (1) all assignments (other than assignments described in Section 11.4(b) hereof) shall be in minimum principal amounts of the lesser
of (X) $1,000,000.00 or (Y) the amount of such Lender’s Revolving Loan Commitment, Incremental Facility Commitment (in a single assignment only) or Incremental Facility Loan, and (2) all assignments and participations (other than
assignments and participations described in Section 11.4(b) hereof) hereunder shall be subject to the following additional terms and conditions: 
 (i) no assignment shall be sold without the prior consent of the Administrative Agent and, prior to the occurrence and continuation of a Default or Event of Default, the consent of the Borrower, in each case, which
consent shall not be unreasonably withheld, delayed or conditioned; 
 (ii) any Person purchasing a participation or an
assignment of any portion of the Loans from any Lender shall be required to represent and warrant that its purchase shall not constitute a “prohibited transaction” (as such term is defined in Section 406 of ERISA or Section 4975
of the Code); 
 (iii) the Borrower, the Lenders, and the Administrative Agent agree that assignments permitted hereunder
(including the assignment of any Advance or portion thereof) may be made with all voting rights, and shall be made pursuant to an Assignment and Assumption Agreement substantially in the form of Exhibit H attached hereto, and an
administrative fee of $3,500.00 shall be payable to the Administrative Agent either by the assigning Lender or the assignee thereof at the time of any assignment under this Section 11.4(c); 
 (iv) no participation agreement shall confer any rights under this Agreement or any other Loan Document to any purchaser thereof, or
relieve any issuing Lender from any of its obligations under this Agreement, and all actions hereunder shall be conducted as if no such participation had been granted; provided, however, that any participation agreement may confer on
the participant the right to approve or disapprove items requiring consent pursuant to Section 11.11 (a)(ii) hereof of an affected Lender for the Loans to which such participation agreement applies; 
  

 -63- 

 (v) each Lender agrees to provide the Administrative Agent and the Borrower with prompt
written notice of any issuance of assignments of its interests hereunder; 
 (vi) no assignment, participation or other
transfer of any rights hereunder or under the Notes shall be effected that would result in any interest requiring registration under the Securities Act of 1933, as amended, or qualification under any state securities law; 
 (vii) no such assignment may be made to any bank or other financial institution (x) with respect to which a receiver or conservator
(including, without limitation, the Federal Deposit Insurance Corporation, the Resolution Trust Company or the Office of Thrift Supervision) has been appointed or (y) that is not “adequately capitalized” (as such term is defined in
Section 131(b)(1)(B) of the Federal Deposit Insurance Corporation Improvement Act as in effect on the Agreement Date); and 
 (viii) each Lender shall, and shall cause each of its assignees to, provide to the Administrative Agent on or prior to the effective date of any assignment an appropriate Internal Revenue Service form as provided in Section 2.12 or as
otherwise required by Applicable Law supporting such Lender’s or assignee’s position that no withholding by the Borrower or the Administrative Agent for United States income tax payable by such Lender or assignee in respect of amounts
received by it hereunder is required. No assignment shall confer any rights to receive any greater payments under Section 10.3 than the applicable Lender would have been entitled to receive with respect to the interest assigned. 
 (d) Except as specifically set forth in Section 11.4(b) or (c) hereof, nothing in this Agreement or the Notes, expressed or implied, is
intended to or shall confer on any Person other than the respective parties hereto and thereto and their successors and assignees permitted hereunder and thereunder any benefit or any legal or equitable right, remedy or other claim under this
Agreement or the Notes. 
 (e) In the case of any participation, all amounts payable by the Borrower under the Loan Documents shall be
calculated and made in the manner and to the parties hereto as if no such participation had been sold. 
 (f) The provisions of this
Section 11.4 shall not apply to any purchase of participations among the Lenders pursuant to Section 2.10 hereof. 
 (g) The
Administrative Agent, acting, for this purpose only, as agent of the Borrower shall maintain, at no extra charge to the Borrower, a register (the “Register”) at the address to which notices to the Administrative Agent are to be sent
under Section 11.1 hereof on which Register the Administrative Agent shall enter the name, address and taxpayer identification number (if provided) of the registered owner of the Loans evidenced by a Note or, upon the request of the registered
owner, for which a Note has been requested. Except as set forth in Section 11.4(b)(ii) hereof, a Note and the Loans evidenced thereby may be assigned or 

  

 -64- 

 
otherwise transferred in whole or in part only by registration of such assignment or transfer of such Note and the Loans evidenced thereby on the Register.
Except as set forth in Section 11.4(b)(ii) hereof, any assignment or transfer of all or part of such Loans and the Note evidencing the same shall be registered on the Register only upon compliance with the other provisions of this
Section 11.4 and surrender for registration of assignment or transfer of the Note evidencing such Loans, duly endorsed by (or accompanied by a written instrument of assignment or transfer duly executed by) the registered owner thereof, and
thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated assignee(s) or transferee(s) and, if less than the aggregate principal amount of such Notes is thereby transferred, the assignor or transferor.
Prior to the due presentment for registration of transfer of any Note, the Borrower and the Administrative Agent shall treat the Person in whose name such Loans and the Note evidencing the same is registered as the owner thereof for the purpose of
receiving all payments thereon and for all other purposes, notwithstanding any notice to the contrary. 
 (h) The Register shall be available
for inspection by the Borrower and any Lender, with respect to such Lender’s information, at any reasonable time during the Administrative Agent’s regular business hours upon reasonable prior notice. 
 (i) Notwithstanding any other provision in this Agreement, any Lender that is a fund that invests in bank loans may, without the consent of the
Administrative Agent or the Borrower, pledge all or any portion of its rights under, and interest in, this Agreement and the Notes to any trustee or to any other representative of holders of obligations owed or securities issued, by such fund as
security for such obligations or securities; provided, however, that any transfer to any Person upon the enforcement of such pledge or security interest may only be made subject to the assignment provisions of this Section 11.4.

 (j) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special
purpose funding vehicle (an “SPC”) sponsored by such Granting Lender, identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or
any part of any Advance that such Granting Lender 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 Advance and
(ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The Loans by an SPC hereunder shall be
Revolving Loans and/or, if applicable, Incremental Facility Loans of the Granting Lender to the same extent, and as if, such Loans were made by such Granting Lender. 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 Lender). 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, solely in its capacity as a party hereto and to any other Loan Document, 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 

  

 -65- 

 
11.4, 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 Advances to the Granting Lender 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 Advances and (ii) disclose on a confidential basis any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety,
guarantee or credit or liquidity enhancement to such SPC. This Section 11.4(j) may not be amended without the written consent of any SPC which has been designated in writing as provided in the first sentence hereof and holds any outstanding
Loans. The designation by a Granting Lender of an SPC to fund Advances shall be deemed to be a representation, warranty, covenant and agreement by such Granting Lender to the Borrower and all other parties hereunder that (A) the funding and
maintaining of such Advances by such SPC shall not constitute a “prohibited transaction” (as such term is defined in Section 406 of ERISA or Section 4975 of the Code), and (B) such designation, funding and maintenance would
not result in any interest requiring registration under the Securities Act of 1933, as amended, or qualification under any state securities law. The SPC shall from time to time provide to the Borrower the tax and other forms required pursuant to
Section 2.12 hereof with respect to such SPC as though such SPC were a Lender hereunder. In no event shall the Borrower or any Lender other than the Granting Lender be obligated hereunder to pay any additional amounts under any provision of
this Agreement (pursuant to Article 10 hereof or otherwise) by reason of a Granting Lender’s designation of an SPC or the funding or maintenance of Advances by such SPC, in excess of amounts which the Borrower would have been obligated to pay
if such Granting Lender had not made such designation and such Granting Lender were itself funding and maintaining such Advances. The Administrative Agent shall register the interest of any SPC in an Advance from time to time on the Register
maintained pursuant to Section 11.4(g) hereof. 
 Section 11.5 Accounting Principles. All references in this Agreement to GAAP
shall be to such principles as in effect from time to time. All accounting terms used herein without definition shall be used as defined under GAAP. All references to the financial statements of the Borrower and to Adjusted EBITDA, Senior Secured
Debt, Total Debt, Interest Expense, Consolidated Total Assets and other such terms shall be deemed to refer to such items of the Borrower and its Subsidiaries, on a fully consolidated basis. The Borrower shall deliver to the Lenders at the same time
as the delivery of any quarterly or annual financial statements required pursuant to Section 6.1 or 6.2 hereof, as applicable, (a) a description in reasonable detail of any material variation between the application of GAAP employed in the
preparation of such statements and the application of GAAP employed in the preparation of the next preceding quarterly or annual financial statements, as applicable, and (b) reasonable estimates of the differences between such statements
arising as a consequence thereof. If, within thirty (30) days after the delivery of the quarterly or annual financial statements referred to in the immediately preceding sentence, the Majority Lenders shall object in writing to the
Borrower’s determining compliance hereunder on such basis, (1) calculations for purposes of determining compliance hereunder shall be made on a basis consistent with those used in the preparation of the latest financial statements as to
which such objection shall not have been made, or (2) if requested by the Borrower, the Majority Lenders will negotiate in good faith to amend the covenants herein to give effect to the changes in GAAP in a manner consistent with this Agreement
(and so long as the Borrower complies in good faith with the provisions of this Section 11.5, no Default or Event of Default shall occur hereunder solely as a result of such changes in GAAP). 
  

 -66- 

 Section 11.6 Counterparts. This Agreement may be executed in any number of counterparts, each of
which shall be deemed to be an original, but all such separate counterparts shall together constitute one and the same instrument. 
 Section
11.7 Governing Law. This Agreement and the Notes shall be construed in accordance with and governed by the internal laws of the State of New York applicable to agreements made and to be performed the State of New York. If any action or
proceeding shall be brought by the Administrative Agent or any Lender hereunder or under any other Loan Document in order to enforce any right or remedy under this Agreement or under any Note or any other Loan Document, the Borrower hereby consents
and submits to the jurisdiction of any New York State or U.S. federal court of competent jurisdiction sitting in the County of New York on the date of this Agreement. The Borrower hereby agrees that, to the extent permitted by Applicable Law,
service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrower at the address given in
Section 11.1 hereof and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any
other jurisdiction. 
 Section 11.8 Severability. To the extent permitted by law, any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision
in any other jurisdiction. 
 Section 11.9 Interest. 
 (a) In no event shall the amount of interest due or payable hereunder or under the Notes exceed the maximum rate of interest allowed by Applicable Law, and in the event any such payment is inadvertently made by the
Borrower or inadvertently received by the Administrative Agent or any Lender, then such excess sum shall be credited as a payment of principal, unless, if no Event of Default shall have occurred and be continuing, the Borrower shall notify the
Administrative Agent or such Lender, in writing, that it elects to have such excess sum returned forthwith. It is the express intent hereof that the Borrower not pay and the Administrative Agent and the Lenders not receive, directly or indirectly in
any manner whatsoever, interest in excess of that which may legally be paid by the Borrower under Applicable Law. 
 (b) Notwithstanding the
use by the Lenders of the Base Rate and the LIBOR as reference rates for the determination of interest on the Loans, the Lenders shall be under no obligation to obtain funds from any particular source in order to charge interest to the Borrower at
interest rates related to such reference rates.

 Section 11.10 Table of Contents and Headings. The Table of Contents and the headings of the
various subdivisions used in this Agreement are for convenience only and shall not in any way modify or amend any of the terms or provisions hereof, nor be used in connection with the interpretation of any provision hereof. 
 Section 11.11 Amendment and Waiver. 
 (a) Neither this Agreement nor any Loan Document nor any term hereof or thereof may be amended orally, nor may any provision hereof or thereof be waived orally but only by an instrument in writing signed by or at the written direction of:

 (i) except as set forth in (ii) and (iii) below, the Majority Lenders and, in the case of any amendment, by the
Borrower; 
 (ii) with respect to (A) any increase in the amount of any Lender’s portion of the Commitments or
Commitment Ratios or any extension of any Lender’s Commitments, (B) any reduction or postponement in interest or fees due hereunder or the payment thereof to any Lender without a corresponding payment of such interest or fee amount by the
Borrower, (C) (1) any waiver of any Default due to the failure by the Borrower to pay any sum due to any of the Lenders hereunder or (2) any reduction in the principal amount of the Loans or the Letter of Credit Obligations without a
corresponding payment, (D) any release of the Borrower from this Agreement, except in connection with a merger, sale or other disposition otherwise permitted hereunder (in which case, such release shall require no further approval by the
Lenders), (E) any amendment to the pro rata treatment of the Lenders set forth in Section 2.10 hereof, (F) any amendment of this Section 11.11, of the definition of Majority Lenders, or of any Section herein to the extent that
such Section requires action by all Lenders or the Issuing Banks, (G) any subordination of the Loans in full to any other Indebtedness, or (H) any extension of a Maturity Date, the affected Lenders and in the case of an amendment, the
Borrower, and, if applicable, the Issuing Banks (it being understood that, for purposes of this Section 11.11(a)(2), changes to provisions of the Loan Documents that relate only to one or more of the Revolving Loans or Incremental Facility
Loans shall be deemed to “affect” only the Lenders holding such Loans); and 
 (iii) in the case of any amendment to
any provision hereunder governing the rights, obligations, or liabilities of the Administrative Agent in its capacity as such, the Administrative Agent and by each of the Lenders. 
 (b) Notwithstanding anything herein to the contrary, the provisions of this Agreement (excluding the provisions of Section 2.14 hereof) relating to
the Incremental Facility Loans and the Incremental Facility Commitments may be amended (including without limitation, any such amendment establishing Incremental Facility Commitments) in a manner not inconsistent with Section 2.14 hereof,
pursuant to a written instrument executed among the Borrower, the Lenders holding an Incremental Facility Commitment and the Administrative Agent, and any such amendment shall not require the consent of any other party to this Agreement;
provided, however, that such amendment shall not be binding on the other Lenders until the consent of the applicable Lenders required under Section 11.11(a) is obtained. 
  

 -68- 

 (c) In connection with any proposed amendment, modification, waiver or termination (a “Proposed
Change”) requiring the consent of all Lenders, if the consent of Majority Lenders is obtained, but the consent of the other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained being referred to
as a “Non-Consenting Lender”), then, at the Borrower’s request (and at the Borrower’s sole cost and expense), a Replacement Lender selected by the Borrower and reasonably acceptable to the Administrative Agent, shall have
the right to purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree that they shall, upon the Borrower’s request, sell and assign to such Person, all of the Revolving Loan Commitments and/or Incremental Facility
Commitments and all outstanding Loans of such Non-Consenting Lenders for an amount equal to the principal balance of all Loans held by the Non-Consenting Lenders and all accrued interest and fees and other amounts due (including without limitation
amounts due to such Non-Consenting Lender pursuant to Section 2.9 hereof) or outstanding to such Non-Consenting Lender through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment and Assumption
Agreement substantially in the form on Exhibit H attached hereto. Upon execution of any Assignment and Assumption Agreement pursuant to this Section 11.11(c), (i) the Replacement Lender shall be entitled to vote on any pending
waiver, amendment or consent in lieu of the Non-Consenting Lender replaced by such Replacement Lender, (ii) such Replacement Lender shall be deemed to be a “Lender” for purposes of this Agreement and (iii) such
Non-Consenting Lender shall cease to be a “Lender” for purposes of this Agreement and shall no longer have any obligations or rights hereunder (other than any obligations or rights which according to this Agreement shall survive the
termination of the Revolving Loan Commitments and/or Incremental Facility Commitments). 
 Section 11.12 Entire Agreement. Except as
otherwise expressly provided herein, this Agreement, the other Loan Documents and the other documents described or contemplated herein or therein will embody the entire agreement and understanding among the parties hereto and thereto and supersede
all prior agreements and understandings relating to the subject matter hereof and thereof. 
 Section 11.13 Other Relationships; No
Fiduciary Relationships. No relationship created hereunder or under any other Loan Document shall in any way affect the ability of the Administrative Agent, each Issuing Bank and each Lender to enter into or maintain business relationships with
the Borrower or any Affiliate thereof beyond the relationships specifically contemplated by this Agreement and the other Loan Documents. The Borrower agrees that in connection with all aspects of the transactions contemplated hereby and any
communications in connection therewith, the Borrower, its Subsidiaries and their respective Affiliates, on the one hand, and the Administrative Agent, the Lenders, the Issuing Banks and their respective Affiliates, on the other hand, will have a
business relationship that does not create, by implication or otherwise, any fiduciary duty on the part of the Administrative Agent, any Lender, any Issuing Bank or any of their respective Affiliates, and no such duty will be deemed to have arisen
in connection with any such transactions or communications. 
 Section 11.14 Directly or Indirectly. If any provision in this
Agreement refers to any action taken or to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person, whether or not expressly
specified in such provision.

 Section 11.15 Reliance on and Survival of Various Provisions. All covenants, agreements,
statements, representations and warranties made by the Borrower herein or in any certificate delivered pursuant hereto shall (a) be deemed to have been relied upon by the Administrative Agent, each of the Lenders and each Issuing Bank
notwithstanding any investigation heretofore or hereafter made by them and (b) survive the execution and delivery of this Agreement and shall continue in full force and effect so long as any Loans are outstanding and unpaid. Any right to
indemnification hereunder, including, without limitation, rights pursuant to Sections 2.9, 2.11, 10.3 and 11.2 hereof, shall survive the termination of this Agreement and the payment and performance of all Obligations. 
 Section 11.16 Senior Debt. The Obligations are intended by the parties hereto to be senior in right of payment to any Indebtedness of the Borrower
that by its terms is subordinated to any other Indebtedness of the Borrower. 
 Section 11.17 Obligations. The obligations of the
Administrative Agent, each of the Lenders and each of the Issuing Banks hereunder are several, not joint. 
 Section 11.18
Confidentiality. The Administrative Agent, the Lenders and the Issuing Banks shall hold confidentially all non-public and proprietary information and all other information designated by the Borrower as confidential, in each case, obtained
from the Borrower or its Affiliates pursuant to the requirements of this Agreement in accordance with their customary procedures for handling confidential information of this nature and in accordance with safe and sound lending practices;
provided, however, that the Administrative Agent, the Lenders and the Issuing Banks may make disclosure of any such information (a) to their examiners, Affiliates, outside auditors, counsel, consultants, appraisers, other
professional advisors and any direct or indirect contractual counterparty in swap agreements or such counterparty’s professional advisor in connection with this Agreement or as reasonably required by any proposed syndicate member or any
proposed transferee or participant in connection with the contemplated transfer of any Note or participation therein (including, without limitation, any pledgee referred to in Section 11.4(i) hereof), in each case, so long as any such Person
(other than any examiners) receiving such information is advised of the provisions of this Section 11.18 and agrees to be bound thereby, (b) as required or requested by any governmental authority or self-regulatory body or representative
thereof or in connection with the enforcement hereof or of any Loan Document or related document or (c) pursuant to legal process or with respect to any litigation between or among the Borrower and any of the Administrative Agent, the Lenders
or the Issuing Banks. In no event shall the Administrative Agent, any Lender or any Issuing Bank be obligated or required to return any materials furnished to it by the Borrower. The foregoing provisions shall not apply to the Administrative Agent,
any Lender or any Issuing Bank with respect to information that (i) is or becomes generally available to the public (other than through the Administrative Agent, such Lender or such Issuing Bank), (ii) is already in the possession of the
Administrative Agent, such Lender or such Issuing Bank on a non-confidential basis, or (iii) comes into the possession of the Administrative Agent, such Lender or such Issuing Bank from a source other than the Borrower or its Affiliates in a
manner not known to the Administrative Agent, such Lender or such Issuing Bank to involve a breach of a duty of confidentiality owing to the Borrower or its Affiliates.

EXTENT PERMITTED BY LAW, TO WAIVE AND HEREBY WAIVE THE RIGHT TO A TRIAL BY JURY IN ANY COURT AND IN ANY ACTION OR PROCEEDING OF ANY TYPE IN WHICH THE BORROWER, ANY OF THE LENDERS, THE ADMINISTRATIVE AGENT, ANY OF THE ISSUING BANKS, OR ANY OF THEIR

ACTUAL DAMAGES. EACH PARTY TO THIS AGREEMENT (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE ADMINISTRATIVE AGENT, ANY ISSUING BANK OR ANY LENDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE ADMINISTRATIVE AGENT, ANY ISSUING
BANK OR ANY LENDER WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND EACH OTHER LOAN DOCUMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS
AND CERTIFICATIONS IN THIS SECTION. THE PROVISIONS OF THIS SECTION HAVE BEEN FULLY DISCLOSED BY AND TO THE PARTIES AND THE PROVISIONS SHALL BE SUBJECT TO NO EXCEPTIONS. NO PARTY HAS IN ANY WAY AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE
PROVISIONS OF THIS SECTION WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.
