 THIRD AMENDMENT TO THE 
 SECOND SUPPLEMENT TO THE 
 DYNEGY INC. EXECUTIVE SEVERANCE PAY PLAN 
  
 WHEREAS, Dynegy Inc. (the “Company”) and certain
subsidiaries and affiliated entities have heretofore established the Dynegy Inc. Executive Severance Pay Plan (the “Plan”); 
  
 WHEREAS, the Company has heretofore adopted the Second Supplement to the Dynegy Inc. Executive Severance Pay Plan (the “Second
Supplement”) on behalf of itself and all of its subsidiaries and affiliated entities that participate in the Plan; 
  
 WHEREAS, the Company has adopted an amendment (the “First Amendment”) to the Second Supplement; 
  
 WHEREAS, the Company maintains certain plans under which stock options
have been granted to eligible employees (the “Stock Option Plans”); 
  
 WHEREAS, the Company desires to amend the Second Supplement on behalf of itself and its participating subsidiaries and affiliated entities in order to clarify that the First Amendment was not intended to
restrict any discretionary power or authority provided for in the Stock Option Plans, including, without limitation, the power or authority to make any changes to or (together with any appropriate payment, if applicable, provided for in the relevant
plan) cancellations of outstanding stock options in connection with a change in control; and 
  
 WHEREAS, Section 4.3 of the Second Supplement provides that the Board of Directors of the Company (or the Compensation Committee of the Board) may amend the Second Supplement; 
  
 NOW, THEREFORE, the Second Supplement is hereby amended as follows,
effective as of June 22, 2005: 
  
 1. Section 3.1(c) of
the Second Supplement is amended in its entirety to provide as follows: 
  
 “All of the Covered Individual’s outstanding stock options, restricted stock awards, phantom stock and other equity-based awards previously granted by his Employer(s) shall become fully vested and
immediately exercisable in full on the date of a Change in Control and such stock options shall remain exercisable from such date for the lesser of: (1) five (5) years from the date of such a Change in Control; (2) the remaining
period of time for exercise of such stock options under the option
 agreement(s) pursuant to which such stock options were granted (irrespective of any mandatory exercise period specified therein that would otherwise be triggered by the
termination of employment of such Covered Individual); or (3) such period of time (which period of time may 

 end as early as the consummation of a Change in Control) as the Board of Directors may determine in
connection with or in contemplation of a Change in Control in the exercise of its discretion under the applicable stock option plans, with respect to which the Board of Directors has the discretion to, among other things, require the surrender of
stock options (which surrender may be in exchange for a cash payment, if applicable) and to cancel such stock options upon the consummation of a Change in Control as further described in the applicable stock option plans;” 
  
 2. Section 4.12 of the Second Supplement is amended in its entirety to
provide as follows: 
  
 “4.12 Equity-Based
Awards. This Section 4.12 applies only to Covered Individuals whose employment is not subject to an Involuntary Termination. Covered Individuals whose employment is subject to an Involuntary Termination are subject to the provisions of
Subsection 3.1(c) hereof. Any outstanding stock options, restricted stock awards, phantom stock and other equity-based awards previously granted to a Covered Individual by his Employer(s) shall immediately vest upon a Change in Control involving a
Covered Individual’s Principal Business Unit (but only with respect to Principal Business Unit Covered Individuals) or, in the alternative, a Change in Control involving Dynegy Inc. (with respect to all Covered Individuals). With respect to any
outstanding stock options vested pursuant to this Section 4.12, such stock options shall remain fully exercisable by such Covered Individuals for the lesser of: (1) five (5) years from the date of such a Change in Control, provided,
that in the case of a Change in Control involving Dynegy Inc., such exercise period shall not be subject to the five-year limitation set forth in this clause (1); (2) the remaining period of time for exercise of such stock options under the
option agreement(s) pursuant to which such stock options were granted; or (3) such period of time (which period of time may end as early as the consummation of a Change in Control) as the Board of Directors may determine in connection with or
in contemplation of a Change in Control in the exercise of its discretion under the applicable stock option plans, with respect to which the Board of Directors has the discretion to, among other things, require the surrender of stock options (which
surrender may be in exchange for a cash payment, if applicable) and to cancel such stock options upon the consummation of a Change in Control as further described in the applicable stock option plans. If a Covered Individual’s employment
becomes subject to an Involuntary Termination after his stock options have vested under this Section 4.12, the stock option exercise provisions of Subsection 3.1(c) shall apply upon such Covered Individual becoming subject to an Involuntary
Termination.” 
  
 3. Except as modified herein, the Second
Supplement shall remain in full force and effect.

 ARTICLE II 
  
 LETTERS OF CREDIT AND REVOLVING LOANS 
  
 SECTION 2.01. Issuance of Letters of Credit. 
  
 (a) General. 
  
 (i) Subject to the terms and conditions of this Agreement (including Sections 2.17, 4.01 and 4.02 hereof), the Borrower may request
of either Issuing Bank the issuance of a Letter of Credit for the account of the Borrower by delivery to the relevant Issuing Bank of a completed Letter of Credit Application, at any time and from time to time during the Availability Period in an
aggregate amount not to exceed at any time outstanding the Lenders’ LC Commitment. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any Letter of Credit Application or other
agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Banks relating to any Letter of Credit, the terms and conditions of this Agreement shall control. 
  
 (ii) Promptly after receipt of any Letter of Credit
Application, the relevant Issuing Bank will confirm with the Payment Agent (by telephone or in writing) that the Payment Agent has received a copy of such Letter of Credit Application from the Borrower and, if not, such Issuing Bank will provide the
Payment Agent with a copy thereof. Upon receipt by such Issuing Bank of confirmation from the Payment Agent that the requested issuance or amendment is permitted in accordance with the terms hereof, then, subject to the terms and conditions hereof,
such Issuing Bank shall, on the requested date, issue a Letter of Credit for the account of the Borrower or its Affiliate or enter into the applicable amendment, as the case may be, in each case in accordance with such Issuing Bank’s usual and
customary business practices. No Issuing Bank shall be obligated to make any independent determination as to whether the requested issuance or amendment is permitted in accordance with the terms hereof, and, unless and until such Issuing Bank
receives such confirmation from the Payment Agent, such Issuing Bank shall have no obligation to issue the requested Letter of Credit. 
  
 (iii) If the Borrower so requests in any applicable Letter of Credit Application, any Issuing Bank may, in its sole and absolute
discretion, agree to issue an Auto-Renewal Letter of Credit. Unless otherwise directed by such Issuing Bank, the Borrower shall not be required to make a specific request to such Issuing Bank for any such renewal. Once an Auto-Renewal Letter of
Credit has been issued, the Borrower and the Lenders shall be deemed to have authorized (but may not require) such Issuing Bank to permit the renewal of such Letter of Credit at any time to an expiry date not later than the Letter of Credit
Termination Date; provided that such Issuing Bank may give a notice of non-renewal and thereby prevent the renewal of an Auto-Renewal Letter of Credit if such Issuing Bank has determined at any time within 30 calendar days prior to the
Nonrenewal Notice Date of such Auto-Renewal Letter of Credit that it would have no obligation at such time to issue such Letter of Credit in its renewed form under the terms hereof (by reason of the provisions of Section 2.01(a)(iv),
Section 2.01(a)(v), or otherwise). 
  

 20 

 (iv) No Issuing Bank shall be under any obligation to issue any Letter of Credit if:

  
 (A) any order, judgment or decree of any
Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such Issuing Bank from issuing such Letter of Credit, or any Law applicable to such Issuing Bank or any request or directive (whether or not having the force of
law) from any Governmental Authority with jurisdiction over such Issuing Bank shall prohibit, or request that such Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon
such Issuing Bank with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such Issuing Bank is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such Issuing Bank
any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which such Issuing Bank in good faith deems material to it; 
  
 (B) the expiry date of such requested Letter of Credit would occur after the earlier of (1) the first anniversary of its date of
issuance (other than with respect to any Auto-Renewal Letter of Credit) and (2) the Letter of Credit Termination Date; 
  
 (C) the issuance of such Letter of Credit would violate one or more generally applicable policies of such Issuing Bank; or 
  
 (D) any of the conditions precedent set forth in
section 4.02 (and with respect to the initial issuance of any Letter of Credit hereunder, section 4.01) has not been satisfied. 
  
 (v) The Borrower may obtain Letters of Credit for itself and on behalf of any of its Affiliates; provided, however, the Payment Agent and
the Issuing Banks agree that the Borrower may maintain the Existing Letters of Credit issued in favor of the DMS Entities even after the DMS Sale is consummated so long as the Required Reserve is maintained. Notwithstanding the foregoing, upon the
expiry date of any Existing Letters of Credit issued on behalf of DMS Entities, the Borrower acknowledges and agrees that after the Closing Date it shall not be permitted to obtain Letters of Credit on behalf of DMS Entities who are no longer
Affiliates of the Borrower. 
  
 (vi) No Letter of
Credit may be issued, amended, renewed or extended if at the time that action is requested it is unlawful or, by reason of any Change of Law, impossible for the Issuing Banks to issue, amend, renew or extend a Letter of Credit or for any Lender to
participate in that Letter of Credit. 
  
 (b) Notice of
Issuance, Amendment, Renewal, Extension; Certain Conditions. 
  
 (i) To request the issuance, amendment, renewal or extension of a Letter of Credit (other than with respect to any Letter of Credit issued under the Existing Credit Agreement) the Borrower must hand-deliver or
telecopy (or transmit by electronic 
  

 21 

 communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the
applicable Issuing Bank and the Co-Administrative Agent a completed Letter of Credit Application setting forth the requested date of such issuance, amendment, renewal or extension. Such Letter of Credit Application must be received by the Payment
Agent and the relevant Issuing Bank no later than 11:00 a.m. (eastern time) at least two (2) Business Days (or such later date and time as such Issuing Bank may agree in a particular instance in its sole discretion) prior to the proposed
issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to such Issuing Bank:
(A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the account
party or parties thereof; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; (G) the transactions or obligations to be supported thereby and (H) such other information as shall
be necessary to prepare the requested Letter of Credit; provided, that in the case of Letters of Credit to be issued on the Closing Date only, the two (2) Business Day prior written notice shall be eliminated. In the case of a request
for an amendment of any outstanding Letter of Credit, such Letter of Credit Application shall specify in form and detail reasonably satisfactory to the relevant Issuing Bank (1) the Letter of Credit to be amended; (2) the proposed date of
amendment thereof (which shall be a Business Day); (3) the nature of the proposed amendment; and (4) such other matters consistent with the items set forth in clauses (A)-(H) in the preceding sentence as such Issuing Bank may
reasonably require. Renewals of, and amendments to increase the available amount under, any outstanding Letters of Credit will be effectuated by the applicable Issuing Bank within one Business Day of the applicable Issuing Bank’s receipt of a
renewal or a request for an increase. The Borrower’s request to reduce the effective face amount of any Letter of Credit shall be effective upon the applicable Issuing Bank’s receipt of a written consent of the beneficiary of such Letter
of Credit consenting to such reduction. 
  
 (ii)
In the case of the letters of credit issued pursuant to the Existing Credit Agreement, each of the Issuing Banks and the Borrower agrees to treat such letters of credit as having been issued pursuant to the terms of this Agreement and to deem the
Letter of Credit Applications previously provided by the Borrower with respect to each such letter of credit under the Existing Credit Agreement to be amended to refer to this Agreement, in each case, as of the Closing Date. 
  
 (iii) Notwithstanding anything to the contrary in the
foregoing, a Letter of Credit may be issued, amended, renewed or extended only if, after giving effect to that issuance, amendment, renewal or extension, the aggregate LC Exposure does not exceed the LC Commitment. Following the receipt of a notice
of amendment or reduction complying with this Section 2.01(b), promptly upon the surrender of the existing Letter of Credit for cancellation (or other arrangements satisfactory to the Issuing Banks), and only if there shall have been no LC
Disbursements with respect to such existing Letter of Credit which have not been reimbursed by the Borrower, the Issuing Banks shall issue a replacement Letter of Credit to the beneficiary of such Letter of Credit, as applicable. 
  

 22 

 (c) Expiration Date. Each Letter of Credit shall have an expiry date at or prior to 10:00 a.m. on
the Letter of Credit Termination Date. Notwithstanding the foregoing; in the case of any Letter of Credit, which by virtue of the application of the provisions of the Uniform Customs and Practice for Documentary Credits, 1993 Revision, International
Chamber of Commerce Publication No. 500 (the “UCP”), may expire after the Letter of Credit Termination Date, such Letter of Credit shall expire two weeks after the last day of possible presentation under the UCP.

obligation to reimburse such LC Disbursement. 
  
 SECTION
2.03. Reimbursement. 
  
 (a) If an Issuing Bank shall make

LC Disbursement no later than 1:00 p.m., New York City time, on the Business Day following the day that the LC Disbursement is made (the “Due Date”). Unless the Borrower shall reimburse such
LC Disbursement in full by 1:00 p.m. on the same day in which such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day commencing on the date the LC Disbursement is made until (but excluding) the date that the
Borrower pays the Payment Agent for the account of the Issuing Banks the amount of such LC Disbursement at the rate equal to the Alternate Base Rate plus the Applicable Margin. 
  
 (b) If the Borrower fails to reimburse an Issuing Bank for any LC Disbursement by the Due Date in accordance with clause
(a) above, the Payment Agent shall notify the LC Collateral Agent to direct the LC Depositary Bank to withdraw an amount equal to such LC Disbursement and unpaid interest accrued thereon and distribute such amount to the Payment Agent for
payment to the applicable Issuing Bank and/or the LC Lenders, as applicable, in accordance with the LC Cash Collateral Account Agreement. Each Issuing Bank and the LC Lenders hereby agree that their sole initial recourse upon the occurrence of an
Event of Default or otherwise hereunder, in respect of the Collateral, shall be to receive the amounts on deposit in the Cash Collateral Account, and that none of them shall make any claim on, or seek to foreclose upon any other Collateral granted
under the Collateral Documents until the amounts on deposit in the Cash Collateral Account have been exhausted. 
  

 26 

 (c) If for any reason an LC Disbursement is not repaid in full by the Borrower or from proceeds available
in the Cash Collateral Account pursuant to clauses (a) or (b) above on the Due Date, the Payment Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such
Lender’s Applicable Percentage thereof. Promptly following receipt of that notice, each Lender shall pay to the Payment Agent its Applicable Percentage of such LC Disbursement, and the Payment Agent will promptly pay to the Issuing Banks the
amounts so received by it from the Lenders. Promptly following receipt by the Payment Agent of any amounts pursuant to Section 2.03(a) or Section 2.03(b), the Payment Agent will distribute that payment to the Issuing Banks or, to the
extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Banks, then to those Lenders and the Issuing Banks as their interests may appear. Any payment made by a Lender pursuant to this clause (c) to reimburse
the Issuing Banks for any LC Disbursement shall be treated as the funding of a portion of such Lender’s Commitment. To the extent that any Lender fails to pay any amount required to be paid pursuant to this Section 2.03(c), that Lender
shall pay interest to the Issuing Banks (through the Payment Agent) on that amount from and including that due date to but excluding the date that payment is made (i) during the period from and including that due date to but excluding the date
three Business Days thereafter, at a rate per annum equal to the Federal Funds Effective Rate (as in effect from time to time) and (ii) thereafter, at a rate per annum equal to the Alternate Base Rate. The obligation of each Lender to so
reimburse the Letter of Credit Issuer shall be absolute and unconditional and shall not be affected by the occurrence of a Default or an Event of Default or any other occurrence, condition or event. Any such reimbursement shall not relieve or
otherwise impair the obligation of the Borrower to reimburse the Issuing Banks for the LC Disbursement, together with interest as provided herein. 
  
 SECTION 2.04. Obligations Absolute. 
  
 (a) The obligations of the Borrower under this Agreement to reimburse any relevant Issuing Bank for each drawing under each Letter of Credit and (without
duplication) to repay each LC Disbursement, shall be unconditional and absolute and shall not be affected, modified or impaired by the happening at any time or from time to time of any event, including any of the following, whether or not with

or acts on the part of an Issuing Bank, an Administrative Agent, any Lender, the Borrower or the beneficiary of any Letter of Credit; 
  
 (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all the assets of, the

right that the Borrower may have at any time against an Issuing Bank, any Lender or any beneficiary of any Letter of Credit (or any persons or entities for whom an Issuing Bank, any such Lender or any such beneficiary may be acting), or any other
Person, whether in connection with any Loan Document, any of the transactions contemplated by any Loan Document or any unrelated transaction;

Banks’ gross negligence or willful misconduct when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that:

 29 

 (vii) each Issuing Bank may select any affiliate of such Issuing Bank or any other bank
to act as advising, transferring, confirming and/or nominated bank under the law and practice of the place where it is located (unless specifically designated in a Letter of Credit Application).

waive the Issuing Banks’ rights and remedies against the Borrower or place the Issuing Banks under any liability whatsoever to the Borrower. 
  
 (d) This Section 2.04 shall establish the standard of care to be exercised by the Issuing Banks when determining whether drafts and other documents
presented under any Letter of Credit comply with the terms thereof (and the parties hereto hereby waive (on its behalf as well as the behalf of its respective Related Parties), to the extent permitted by applicable law, any standard of care

LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the applicable Issuing Bank and the Lenders with respect to any such
LC Disbursement. The Borrower acknowledges and agrees that the Issuing Banks shall have the right to honor demands for payments under a Letter of Credit that are submitted by a beneficiary via telecopy if such Letter of Credit provides for
submission by telecopy. 
  
 SECTION 2.06. Modification,
Reduction and Reinstatement.

consented to such modification or supplement (such consent not to be unreasonably withheld or delayed); provided that such modification or supplement will not be deemed to be a new extension of credit hereunder unless the amount available for
drawing under such Letter of Credit is increased. 
  

 30 

 (b) Reduction and Reinstatement. Upon an LC Disbursement under a Letter of Credit, the amount
available to be drawn under such Letter of Credit shall be reduced by an amount equal to the amount of such LC Disbursement. Subject to this Section 2.06 and the applicable Letter of Credit, the applicable Issuing Bank shall reinstate such

of such reinstatement or, in the case where proceeds from the Cash Collateral Account have been applied to reimburse the applicable Issuing Bank for the LC Disbursement and interest thereon pursuant to Section 2.03(b), the Borrower shall have
deposited with the LC Depositary Bank an amount sufficient to replenish the Cash Collateral Account in the amount of the LC Disbursement and interest accrued thereon.

Revolving Loan Commitments, whether or not then due. The Revolving Loan Cash Collateral Account shall be maintained at all times in accordance with the terms of the Revolving Loan Cash Collateral Account Agreement until the Revolving Loan

 (ii) Upon the reduction, termination or expiration of a Letter of Credit or at any time that the Payment Agent has determined that the LC Cash Collateral Account has Excess Collateral described in clause (b) of
the definition thereof, then within one (1) Business Days of a request of the Borrower, the Payment Agent shall notify the Collateral Agent in writing, and the LC Collateral Agent agrees to instruct the LC Depositary Bank to release to, or to

 SECTION 2.10. Fees. 
  
 (a) Fronting Fee and Documentary and Processing Charges Payable to Issuing Bank. The Borrower hereby agrees to pay to the relevant Issuing Bank
solely for its benefit, (i) in the case of Letters of Credit that are standby Letters of Credit a Letter of Credit fronting fee equal to a per annum amount (calculated for the actual number of days elapsed on the basis of a year consisting of
365, or when appropriate 366, days) in the amount agreed to in the LC Fee Letter on the daily average available amount under each such Letter of Credit issued, increased or extended by such Issuing Bank from and including the date issued, increased
or extended to and including the date of its expiration or earlier termination, (ii) in the case of Letters of Credit that are commercial Letters of Credit a Letter of Credit fronting fee equal to a per annum amount (calculated for the actual

such Issuing Bank from and including the date issued, increased or extended to and including the date of its expiration or earlier termination, and (iii) a fee for each issuance, amendment or renewal of, and for each negotiation of a draft

respect to each outstanding Letter of Credit commencing on the first such date to occur after such Letter of Credit is issued, increased or extended. The Payment Agent shall promptly remit to the relevant Issuing Bank any Letter of Credit fronting
fee due to such Issuing Bank after the Payment Agent’s receipt of such fee. 
  

 34 

 (b) Letter of Credit Fees. The Borrower agrees to pay or cause to be paid to the Payment Agent for
the account of the Issuing Banks and each Lender (if any) the following fees (collectively with the fees described in clauses (a) of this Section 2.10, the “Letter of Credit Facility Fees”) with respect to its pro
rata portion of the LC Exposure (less, in the case of the Issuing Banks, the LC Exposure of the Lenders’ participations in the Letters of Credit): 
  
 (i) a letter of credit fee in an amount equal to a daily rate of .50% per annum during which any Letter of Credit shall remain
outstanding, multiplied by the average daily aggregate undrawn stated amount available from time to time to be drawn under the outstanding Letters of Credit for each day occurring during the immediately preceding month; and 
  
 (ii) a commitment fee in an amount equal to a daily rate of
..10% per annum multiplied by the excess, if any, of the average daily aggregate unused amount of the LC Commitment. 
  
 The Letter of Credit Facility Fees described in this Section 2.10(b) shall be payable monthly in arrears on each monthly anniversary of the Closing Date and on the
Letter of Credit Termination Date. Unless otherwise paid by the Borrower, the Payment Agent shall notify the Collateral Agent to direct the LC Depositary Bank to withdraw from the Cash Collateral Account the monthly Letter of Credit Facility Fees

pay or cause to be paid to the Payment Agent for the account of each Revolving Loan Lender in accordance with its Pro Rata Share and/or Citigroup Global Markets, Inc., as applicable, the following fees (collectively, the “Revolving Loan

 (i) a commitment fee for the period from and including the Closing Date to but not including the last day of the Availability Period, computed at a rate equal to 0.10% per annum times the actual daily
amount by which the aggregate Revolving Loan Commitments exceed the sum of the outstanding amounts of the Revolving Loans; provided that any commitment fee accrued with respect to any of the Revolving Loan Commitments of a Defaulting Lender
during the period prior to the time such Lender became a Defaulting Lender and unpaid at such time shall not be payable by the Borrower so long as such Lender shall be a Defaulting Lender except to the extent that such commitment fee shall otherwise
have been due and payable by the Borrower prior to such time; and provided further that no commitment fee shall accrue on any of the Revolving Loan Commitments of a Defaulting Lender so long as such Lender shall be a Defaulting Lender.
The commitment fee shall accrue at all times during the Availability Period, including at any time during which one or more of the conditions in Section 4.03 is not met, and shall be due and payable quarterly in arrears on the fifth Business
Day following receipt by the Borrower of an invoice with appropriate back up, commencing with the first such date to occur after the Closing Date, and on the Revolving Loan Termination Date. The commitment fee shall be calculated quarterly in
arrears; and 
  

 35 

 (ii) such fees as shall have been separately agreed upon in the Revolving Loan Fee
Letter. Such fees shall be fully earned when paid and shall not be refundable for any reason whatsoever. 
  
 (d) Payment of Fees. Except as otherwise provided in Section 2.10(a), (b) or (c), all fees payable hereunder shall be paid on the dates
due, in immediately available funds, to the Payment Agent (or to the applicable Issuing Bank, in the case of fees payable to it) for distribution, in the case of Letter of Credit Facility Fees, to the LC Lenders entitled thereto and, in the case of
the Revolving Loan Commitment Fees, to the Revolving Loan Lenders. 
  
 SECTION 2.11. Increased Costs. 
  
 (a)
Increased Costs Generally. If any Change in Law shall increase the cost (other than costs relating to Taxes, which shall be solely dealt with pursuant to Section 2.12) to any Lender or the Issuing Banks of participating in, issuing or
maintaining any Letter of Credit or making any Loan or to reduce the amount of any sum received or receivable by such Lender or the Issuing Banks hereunder, then the Borrower will pay to such Lender or the Issuing Banks, as the case may be, such
additional amount or amounts as will compensate such Lender or the Issuing Banks, as the case may be, for such additional costs incurred or reduction suffered. 
  

(b) Capital Requirements. If any Lender or the Issuing Banks determine that any Change in Law regarding capital requirements has or would have
the effect of reducing the rate of return on such Lender’s or any Issuing Banks’ capital or on the capital of such Lender’s or an Issuing Banks’ holding company, if any, as a consequence of this Agreement or the participations in
a Letter of Credit held by, such Lender, or a Letter of Credit issued by an Issuing Bank, or the making of any Loan to a level below that which such Lender or the Issuing Banks or such Lender’s or an Issuing Banks’ holding company could
have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Banks’ policies and the policies of such Lender’s or an Issuing Banks’ holding company with respect to capital adequacy), then from
time to time the Borrower will pay to such Lender or the Issuing Banks, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Banks or such Lender’s or an Issuing Banks’ holding company for any
such reduction suffered. 
  
 (c) Certificates from Lenders.
A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section
shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

  
 (d) Delay in Requests. Failure or delay on the part of
any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required
to compensate a Lender or an Issuing Bank pursuant to this 
  

 36 

 Section for any increased costs or reductions incurred more than six months prior to the date that such Lender or such
Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided
further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof. 
  
 SECTION 2.12. Taxes. 
  
 (a) Payments Free of Taxes. Any and all payments by or on account of
any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the
Paying Agent, Lender or Issuing Banks (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full
amount deducted to the relevant Governmental Authority in accordance with applicable law. 
  
 (b) Payment of Other Taxes by the Borrower. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
  
 (c) Indemnification by the Borrower. The Borrower shall indemnify the
Agents, each Lender (if any) and the Issuing Banks, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to
amounts payable under this Section) paid by any of the Agents, such Lender or the Issuing Banks, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes
or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or an Issuing Bank, or by the Payment Agent on its
own behalf or on behalf of a Lender or an Issuing Bank, shall be conclusive absent manifest error. 
  
 (d) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority,
the Borrower shall deliver to the Payment Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably
satisfactory to the Payment Agent. 
  
 (e) Foreign Lenders.
Each Foreign Lender shall deliver to the Payment Agent, prior to receipt of any payment subject to withholding under the Code (or upon accepting an assignment of an interest herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Foreign Lender and entitling it to an exemption from, or reduction of, withholding tax on all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any
successor thereto (relating to all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement) or such other evidence satisfactory to the Borrower and the Payment Agent that such Foreign 
  

 37 

 Lender is entitled to an exemption from, or reduction of, U.S. withholding tax, including any exemption pursuant to
Section 881(c) of the Code, and in the case of a Foreign Lender claiming such an exemption under Section 881(c) of the Code, a certificate that establishes in writing to the Payment Agent that such Foreign Lender is not (i) a
“bank” as defined in Section 881(c)(3)(A) of the Code, (ii) a 10-percent shareholder within the meaning of Section 871(h)(3)(B) of the Code, and (iii) a controlled foreign corporation related to the Borrower within the
meaning of Section 864(d) of the Code. Thereafter and from time to time, each such Foreign Lender shall (A) promptly submit to the Payment Agent such additional duly completed and signed copies of one of such forms (or such successor forms
as shall be adopted from time to time by the relevant United States taxing authorities) as may then be available under then current United States laws and regulations to avoid, or such evidence as is satisfactory to the Borrower and the Payment
Agent of any available exemption from or reduction of, United States withholding taxes in respect of all payments to be made to such Foreign Lender by the Borrower pursuant to this Agreement, (B) promptly notify the Payment Agent of any change
in circumstances which would modify or render invalid any claimed exemption or reduction, and (C) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary
(including the re-designation of its Lending Office) to avoid any requirement of applicable Laws that the Borrower make any deduction or withholding for taxes from amounts payable to such Foreign Lender. 
  
 SECTION 2.13. Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. 
  
 (a) Payments by the Borrower. The
Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (except to the extent otherwise provided therein) prior to 1:00 p.m., New York City time, on the date when due, in immediately available funds,
without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Payment Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such
payments shall be made to the Payment Agent except as otherwise expressly provided in the relevant Loan Document and except payments to be made directly to an Issuing Bank as expressly provided herein and payments pursuant to Sections 2.11,
2.12 and 8.03, which shall be made directly to the Persons entitled thereto. Payments to the Payment Agent shall be made to it at the following account: 
  

			
	CITIBANK, N.A.	  	 
	ABA NO:	  	021000089
	ACCOUNT OF:	  	36852248
	ACCOUNT #:	  	Agency/Medium Term Finance
	REFERENCE:	  	Dynegy
	ATTENTION:	  	Global Loans/Agency

  
 The Payment Agent shall distribute any
such payments received by it for account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the
next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. 
  

 38 

 (b) Application of Insufficient Payments. If at any time insufficient funds are received by and
available to the Payment Agent to pay fully all amounts of unreimbursed LC Disbursements or unpaid accrued Revolving Loan Obligations, interest and fees then due hereunder, such funds shall be applied (i) first, to pay interest and fees
then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, to pay unreimbursed LC Disbursements and unpaid Revolving Loan Obligations then
due hereunder, ratably among the parties entitled thereto in accordance with the amounts of unreimbursed LC Disbursements and unpaid Revolving Loan Obligations then due to such parties. 
  
 (c) Pro Rata Treatment. Except to the extent otherwise provided
herein: (i) each payment of letter of credit fees under Section 2.10(a) shall be made for account of the applicable Issuing Bank and the LC Lenders (if any) pro rata in accordance with the respective LC Exposure held by the applicable
Issuing Bank and each Lender; (ii) each reimbursement of LC Disbursements by the Borrower shall be made for account of the applicable Issuing Bank and the Lenders (if any) pro rata in accordance with the respective unreimbursed LC Disbursements
held by them; (iii) each payment of interest on unreimbursed LC Disbursements shall be made for account of the Issuing Banks and the Lenders (if any) pro rata in accordance with the amounts of interest on such unreimbursed LC Disbursements then
due and payable to the Issuing Banks and Lenders and (iv) each borrowing by the Borrower of Revolving Loans, each payment by the Borrower on account of any commitment fee with respect to Revolving Loans and any reduction of the Revolving Loan
Commitments shall be made in accordance with the respective Pro Rata Shares of the Revolving Loan Lenders, and each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made in
accordance with the respective Pro Rata Shares of the Revolving Loan Lenders. 
  
 (d) Sharing of Payments by Lenders. If an Issuing Bank or any LC Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of its participations in
LC Disbursements, as applicable, resulting in an Issuing Bank or such LC Lender receiving payment of a greater proportion of the aggregate amount of its participations in LC Disbursements, and accrued interest thereon then due than the
proportion received by the applicable Issuing Bank or other LC Lender, then the applicable Issuing Bank or LC Lender receiving such greater proportion shall purchase (for cash at face value) participations in LC Disbursements of the applicable
Issuing Bank or LC Lenders to the extent necessary so that the benefit of all such payments shall be shared by the applicable Issuing Bank and the LC Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on
their respective participations in LC Disbursements; and, if any Revolving Loan Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of Revolving Loan Obligations owing to it, resulting in
such Revolving Loan Lender receiving payment of a greater proportion of the aggregate amount of Revolving Loan Obligations owing to it then due than the proportion received by the other Revolving Loan Lenders, then the applicable Revolving Loan
Lender receiving such greater proportion shall purchase (for cash at face value) participations in Revolving Loans, as applicable, of the Revolving Loan Lenders to the extent necessary so that the benefit of all such payments shall be shared by the
Revolving Loan Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans; provided that in each case above (i) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of 
  

 39 

 such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any
payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by the Issuing Banks or a Lender as consideration for the assignment of or sale of participations in LC Disbursements or
Revolving Loans, as applicable, to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the
extent it may effectively do so under applicable law, that the Issuing Banks or Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
  
 (e) Presumptions of Payment. Unless the Payment Agent shall have received notice from the Borrower prior to the date on which any payment is due to
the Payment Agent for account of the Lenders (if any) or the Issuing Banks hereunder that the Borrower will not make such payment, the Payment Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders or the Issuing Banks, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Banks, as the case may be,
severally agrees to repay to the Payment Agent forthwith on demand the amount so distributed to such Lender or the Issuing Banks with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the
date of payment to the Payment Agent, at the Federal Funds Rate. 
  
 (f) Certain Deductions by the Payment Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.02 or 2.13(d), then the Payment Agent may, in its discretion (notwithstanding any contrary
provision hereof), apply any amounts thereafter received by the Payment Agent for account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
  
 SECTION 2.14. Mitigation Obligations; Replacement of Lenders.

  
 (a) Designation of a Different Lending Office. If any
Lender requests compensation under Section 2.11, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for account of any Lender pursuant to Section 2.12, then such Lender shall use
reasonable efforts to designate a different lending office for funding or booking its obligations hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such
designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.11 or 2.12, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not
otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. 
  
 (b) Replacement of Lenders. Prior to a drawing under any Letter of
Credit, and if no Event of Default shall have occurred and be continuing, if any Lender requests compensation under Section 2.11, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for
account of any Lender pursuant to Section 2.12, 
  

 40 

 then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Payment Agent, require such
Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 8.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations
(which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Co-Administrative Agents and the Issuing Banks, which consent shall not
unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such accrued interest and fees) or the Borrower (in the
case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.11 or payments required to be made pursuant to Section 2.12, such assignment will result in a reduction in
such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and
delegation cease to apply. 
  
 SECTION 2.15. Exoneration;
Independence; Continuing Obligation. 
  
 (a)
Exoneration. The Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit with respect to the use of the Letter of Credit. None of the Issuing Banks, the Agents, the Agent-Related Persons, the Lenders or
any of their respective Related Parties shall be liable or responsible for: (i) the use that may be made of any Letter of Credit or for any acts or omissions of any beneficiary of any Letter of Credit in connection with that Letter of Credit;
(ii) the validity, sufficiency or genuineness of documents presented to the Issuing Banks, or of any endorsement on those documents, even if those documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or
forged; (iii) payment by the Issuing Banks against presentation of documents that do not comply with the terms of any Letter of Credit, including the failure of any documents to bear any reference or adequate reference to that Letter of Credit;
or (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit; provided that the Borrower will have a claim against the Issuing Banks to the extent, but only to the extent, of any direct, as
opposed to consequential, damages suffered by the Borrower that the Borrower proves were caused by (A) the Issuing Banks’ willful misconduct or gross negligence in determining whether a document presented under any Letter of Credit
complies with the terms of that Letter of Credit or (B) the Issuing Banks’ willful failure to pay under any Letter of Credit after the presentation to it of documents strictly complying with the terms and conditions of that Letter of
Credit. In furtherance and not in limitation of the foregoing, the Issuing Banks may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the
contrary. 
  
 (b) Independence; Continuing Obligation. The
Borrower acknowledges that the rights and obligations of the Issuing Banks under any Letter of Credit are independent of the existence, performance or nonperformance of any contract, arrangement or transaction underlying such Letter of Credit.

  

 41 

 SECTION 2.16. Termination or Reduction of Commitments. The Borrower, may upon written notice to
the Payment Agent, terminate the unused portion of the unused Commitments, or from time to time permanently reduce the unused portion of the unused Commitments; provided, that (a) any such notice shall be received by the Payment Agent not later
than 11:00 a.m. (eastern time) three (3) Business Days prior to the date of termination or reduction, (b) the Borrower shall give at least five (5) Business Days’ prior written notice of each such termination or reduction to the
Administrative Agents, and (c) any such partial reduction shall be in a minimum aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess thereof or, if less, the entire amount of the applicable Commitment. Notwithstanding
the foregoing, the Borrower may not reduce the LC Commitment below the then outstanding principal balance of the LC Obligations and may not reduce the unused portion of the Revolving Loan Commitments below the then outstanding principal amount of
Revolving Loan Obligations. No termination or reduction of the Commitment pursuant to this provision may be reinstated without the prior written approval of the Paying Agent, the Administrative Agents, the Issuing Banks, and the Lenders. 

 
 SECTION 2.17. Change of Control. If any Change of Control shall
occur, the Issuing Banks shall no longer have an obligation to issue new Letters of Credit hereunder or amend (other than to reduce the face amount thereof), renew or extend an existing Letter of Credit or make any Revolving Loans. 
  
 SECTION 2.18. Applicability of ISP98 and UCP. Unless otherwise
expressly agreed by the relevant Issuing Bank and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit), (i) the rules of the “International Standby Practices 1998”
published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each standby Letter of Credit, and (ii) the rules of the Uniform Customs and
Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance (including the International Chamber of Commerce decision published by the Commission on Banking Technique and Practice on
April 6, 1998 regarding the European single currency (euro)) shall apply to each commercial Letter of Credit, and in each case to the extent not inconsistent with the above referred rules, the laws of the State of New York shall apply to each
Letter of Credit.

(ii) stating whether any change in GAAP or in the application thereof has occurred since the date of the audited financial statements most recently provided hereunder and, if any such change has occurred, specifying the effect of such change on

 (h) furnish to the Administrative Agents, as soon as possible and in any event within five days after the
Borrower has knowledge of the occurrence of each Event of Default and each event that, with the giving of notice or lapse of time or both, would constitute an Event of Default, continuing on the date of such statement, a statement of a duly
authorized officer of the Borrower setting forth details of such Event of Default or event, as the case may be, and the actions that the Borrower has taken and proposes to take with respect thereto; 
  
 (i) furnish to the Administrative Agents such other information respecting
the condition or operations, financial or otherwise, of the Borrower or any of its Subsidiaries as the Administrative Agents may from time to time reasonably request.

 If any of the following events (“Events of
Default”) shall occur: 
  
 (a) (i) The Borrower
shall fail to pay any amount payable under Section 2.01A(c) or Section 2.03 (after taking into account the application of the proceeds from the applicable Cash Collateral Account described in Section 2.01A(c)(v) or
Section 2.03(b), as applicable, whether or not such proceeds are actually applied) when due, or (ii) the Borrower shall fail to pay any other amount under this Agreement within ten (10) days after the same becomes due and payable; or

  
 (b) Any representation or warranty made by the Borrower (or
any of its officers) herein or in connection with this Agreement shall prove to have been incorrect or misleading in any material respect when made; or 
  
 (c) The Borrower shall fail to perform or observe any term, covenant or agreement contained in Section 5.02; or any other term, covenant or

 50 

 (d) The Borrower shall generally not pay its debts as such debts become due, or shall admit in writing
its inability to pay its debts generally, or shall make a general assignment for the benefit of creditors; or any proceeding shall be instituted by or against the Borrower seeking to adjudicate it a bankrupt or insolvent, or seeking liquidation,
winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the
appointment of a receiver, trustee, custodian or other similar official for it or for any substantial part of its property and, in the case of any such proceeding instituted against it (but not instituted by it), either such proceeding shall remain
undismissed or unstayed for a period of 60 days, or any of the actions sought in such proceeding (including, without limitation, the entry of an order for relief against, or the appointment of a receiver, trustee, custodian or other similar official
for, it or for any substantial part of its property) shall occur; or the Borrower shall take any corporate action to authorize or to consent to any of the actions set forth above in this subsection (d). 
  
 (e) If any Event of Default shall occur and be continuing, then and in every
such event, and at any time thereafter during the continuance of such Event of Default, the Co-Administrative Agents may, and upon request of the LC Required Lenders shall, by written notice to the Borrower, terminate the LC Commitments and the
Issuing Banks shall no longer have an obligation to issue Letters of Credit hereunder, and the Revolving Loan Administrative Agent may, and upon the request of the Revolving Loan Required Lenders shall, by written notice to the Borrower, terminate
the Revolving Loan Commitments, in each case without presentment, demand, protest or any other notice of any kind, all of which are expressly waived; provided that if any Event of Default set forth in Section 6.01(d) hereof shall occur
with respect to the Borrower, then without any notice to the Borrower or any other act by any of the Administrative Agents, the Issuing Banks or any other Lenders or any other Person, the Commitments shall automatically be terminated and the Issuing

to be immediately due and payable, and if any Event of Default set forth in Section 6.01(d) hereof shall occur with respect to the Borrower, then without any notice to the Borrower or any other act by the Administrative Agents, the Issuing
Banks or any other Lenders or any other Person, all such amounts shall automatically become immediately due and payable, in each case without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by the
Borrower; and exercise on their own behalf or on behalf of the other Agents and the Lenders all rights and remedies available to them (subject to Sections 2.03(b) and 2.01A(c)(v)), to the other Agents and to the Lenders under the Loan Documents
(including, without limitation, all of the Collateral Documents) or applicable Law. 
  

 51 

 ARTICLE VII 
  
 THE AGENTS 
  
 SECTION 7.01. Appointment and Authorization of Agents. 
  
 (a) Each Lender hereby irrevocably appoints, designates and authorizes each Agent to take such action on its behalf under the provisions of this Agreement
and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, no Agent shall have any duties or responsibilities, except those expressly set forth herein, nor shall any Agent 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 any Agent.
Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to any Agent is not intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties. 
  
 (b) Each Issuing Bank shall act on behalf of the Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith, and such Issuing Bank Issuer shall have all of the benefits and immunities (i) provided to the Agents in this Article VII with respect to any acts taken or omissions
suffered by such Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term “Agent”
as used in this Article VII and in the definition of “Agent-Related Person” included such Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to such Issuing Bank. 
  
 (c) Each of the Lenders (in its capacities as a Lender and Issuing Bank (if
applicable)) hereby irrevocably appoints and authorizes the applicable Collateral Agent to act as the agent and as the representative of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of
the Loan Parties to secure any of the Secured Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Collateral Agents (and any co-agents, subagents and attorneys-in-fact appointed by
either Collateral Agent or by any Administrative Agent pursuant to Section 7.02 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents, or for exercising any rights and
remedies thereunder at the direction of the applicable Collateral Agent), shall be entitled to the benefits of all provisions of this Article VII (including, without limitation, Section 7.07, as though such co-agents, sub-agents and
attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto. 
  
 (d) Each Lender hereby irrevocably authorizes the applicable Collateral Agent to (i) direct the Collateral Trustees to execute the Mortgage
Supplements, (ii) consent to the 
  

 52 

 amendment to the Collateral Trust Agreement delivered pursuant to the Existing Credit Agreement and (iii) enter into
any other documents necessary to reflect the terms of this Agreement or effectuate the provisions in clauses (i) and (ii), in each case, in accordance with the Collateral Trust Agreement. 
  
 (e) It is understood and acknowledged that, in connection with the DMS Sale,
the Borrower and the Parent Guarantor and the Revolving Loan Lenders have agreed upon terms and conditions pursuant to which the Revolving Loan Lenders would be willing to replace the Revolving Loan Facility with a senior secured term loan facility
in an amount up to $600,000,000, the proceeds of which would be solely used to purchase or redeem second lien notes issued by the Borrower under the Indenture dated as of August 11, 2003 among the Borrower, the Parent Guarantor, the other
guarantors named therein and the Collateral Trustees (such facility, the “Backstop Facility” and the Revolving Loan Lenders who agree to provide such loans the “Backstop Lenders”)). Each LC Lender (in
its capacities as a Lender and/or Issuing Bank, if applicable) and each Agent irrevocably agrees that its consent shall not be required to amend and/or amend and restate this Agreement solely as it relates to the replacement of the Revolving Loan
Facility with the Backstop Facility and the amendments and/or amendment and restatement of this Agreement solely as it relates to the provisions of the Revolving Loan Facility and the amendments described in Section 4.04 for the sole benefit of
the Backstop Lenders; provided, that the Backstop Lenders agree to subordinate their rights in the LC Cash Collateral Account as contemplated in this Section 7.01(e) and provided, further, that such amendments and/or
amendment and restatement do not affect in any adverse manner any of the rights, remedies, and obligations of the LC Lenders and Issuing Banks under this Agreement. In furtherance of the foregoing, the LC Lenders irrevocably authorize the Collateral
Agents, the Payment Agent (including, if applicable, as a Representative) and the Administrative Agents (including, if applicable, each as Representatives, together as the Required Representative, and together with the Payment Agent as all of the
Representatives), as applicable (each, an “Authorized Agent” and collectively the “Authorized Agents”), to enter into and/or direct the Collateral Trustees to enter into, as applicable, such amendments
and/or amendment and restatement of this Agreement and the Loan Documents solely as it relates to effectuating the replacement of the Revolving Loan Facility with the Backstop Facility, including entering into replacements of, and/or
acknowledgements, joinders, notifications or other agreements with respect to, (i) the Shared Collateral Documents as the applicable Authorized Agents reasonably deem necessary to result in (x) the Backstop Lenders sharing, equally and
ratably with the LC Lenders, the LC Lenders’ first priority security interests in the collateral granted under the Shared Collateral Documents and (y) Backstop Lenders otherwise becoming subject to the terms of the Shared Collateral
Documents and (ii) the Cash Collateral Documents as the applicable Authorized Agents reasonably deem necessary to result in (x) the Backstop Lenders sharing, equally and ratably with the Lenders (but subject to the intercreditor
arrangements described in the next following sentence), the Lenders’ first priority security interests in the collateral granted under the Cash Collateral Documents and (y) the Backstop Lenders otherwise becoming subject to the terms of
the Cash Collateral Documents. Each such LC Lender further irrevocably authorizes the Authorized Agents to enter into and/or direct the Collateral Trustees to enter into, as applicable, such intercreditor arrangements as the applicable Authorized
Agents shall reasonably deem necessary to subordinate such security interests of the Backstop Lenders in the collateral granted under the Cash Collateral Documents to the super-priority security interests of the LC Lenders in the LC Cash Collateral
Account and the amounts on deposit therein. Each such Lender hereby ratifies all amendments, amendment and restatements, replacements, acknowledgements, joinders, modifications and/or other agreements or instruments entered into in accordance with
this Section 7.01(e). 
  

 53 

 SECTION 7.02. Delegation of Duties. Any Agent may execute any of its duties under this Agreement
or any other Loan Document (including for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents or of exercising any rights and remedies thereunder at the direction of the
Administrative Agents) by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. No Agent shall be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct. 
  
 SECTION 7.03. Liability of Agents. No Agent-Related Person shall (a) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct in connection with its duties expressly set forth herein), or (b) be
responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by any Loan Party or any officer thereof, contained herein or in any other Loan Document, or in any certificate, report, statement or
other document referred to or provided for in, or received by any Agent under or in connection with, this Agreement or any other Loan Document, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other
Loan Document, or the perfection or priority of any Lien or security interest created or purported to be created under the Collateral Documents, or for any failure of any Loan Party or any other party to any Loan Document to perform its obligations
hereunder or thereunder. No Agent-Related Person shall be under any obligation to any Lender or participant to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books or records of any Loan Party or any Affiliate thereof. Anything in this Agreement to the contrary notwithstanding, in no event shall any Collateral Agent be liable for special, indirect or
consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if such Collateral Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. Neither of the Collateral
Agents shall not be liable for losses or delays caused by force majeure, interruption or malfunction of computer, transmission or communications facilities, labor difficulties, court order or decree, the commencement of bankruptcy or other
similar proceedings or other matters beyond such Collateral Agent’s reasonable control. 
  
 SECTION 7.04. Reliance by Agents. 
  
 (a) Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, electronic mail message, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and
statements of legal counsel (including counsel to any Loan Party), independent accountants and other experts selected by such Agent. Each Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it
shall first receive such advice or concurrence of the applicable Required Lenders as it deems appropriate and, if it so requests, it shall first be 
  

 54 

 indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required
Lenders (or such greater number of Lenders as may be expressly required hereby in any instance) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders. The Lenders hereby acknowledge that each
Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the applicable Required Lenders.
Each Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and
expense that it may incur by reason of taking or continuing to take any such action. 
  
 (b) For purposes of determining compliance with the conditions specified in Article IV, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with,
each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the applicable Administrative Agents shall have received notice from such Lender prior to the proposed Closing Date
specifying its objection thereto. 
  
 SECTION 7.05. Notice of
Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Payment Agent for the account of the
Lenders, unless such Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default and stating that such notice is a “notice of default.” The Administrative Agents will notify
the Lenders of its receipt of any such notice. The Administrative Agents shall take such action, or direct the Collateral Agents to take such action or refrain from taking such action, with respect to such Default as may be directed by the
applicable Required Lenders in accordance with Article VIII; provided that unless and until the Administrative Agents or the Collateral Agents, as the case may be, have received any such direction, the Administrative Agents or the Collateral Agents,
as the case may be, may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as they shall deem advisable or in the best interest of the Lenders. 
  
 SECTION 7.06. Credit Decision. Disclosure of Information by Agents.
Each Lender acknowledges that no Agent-Related Person has made any representation or warranty to it, and that no act by any Agent hereafter taken, including any consent to and acceptance of any assignment or review of the affairs of any Loan Party
or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Agent-Related Person to any Lender as to any matter, including whether Agent-Related Persons have disclosed material information in their possession. Each
Lender represents to each Agent that it has, independently and without reliance upon any Agent-Related Person and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business,
prospects, operations, property, financial and other condition and creditworthiness of the Loan Parties and their respective Subsidiaries, and all applicable bank or other regulatory Laws relating to the transactions contemplated hereby, and made
its own decision to enter into this Agreement and to extend credit to the Borrower and the other Loan Parties hereunder. Each Lender also represents 
  

 55 

 that it will, independently and without reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems
necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. Except for notices, reports and other documents expressly required to be
furnished to the Lenders by any Agent herein, such Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or
creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Agent-Related Person. 
  
 SECTION 7.07. Indemnification of Agents. Whether or not the transactions contemplated hereby are consummated, the Lenders shall indemnify upon
demand each Agent-Related Person (to the extent not reimbursed by or on behalf of any Loan Party and without limiting the obligation of any Loan Party to do so), pro rata, and hold harmless each Agent-Related Person from and against any and all
Indemnified Liabilities incurred by it; provided that no Lender shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified Liabilities to the extent determined in a final, nonappealable judgment by a court of
competent jurisdiction to have resulted from such Agent-Related Person’s own gross negligence or willful misconduct; provided that no action taken by any Agent-Related Person in accordance with the directions of the applicable Required Lenders,
and no action taken or refrained from being taken by the applicable Collateral Agent at the direction of a Administrative Agent or the Payment Agent, shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section.
In the case of any investigation, litigation or proceeding giving rise to any Indemnified Liabilities, this Section 7.07 applies whether any such investigation, litigation or proceeding is brought by any Lender or any other Person. As used
herein, “Indemnified Liabilities” for each Agent-Related Person means (i) any amounts not reimbursed by the Borrower for which such Agent-Related Person is entitled to reimbursement by the Borrower under the Loan
Documents, (ii) any other reasonable expenses incurred by such Agent-Related Person on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without
limitation, for any reasonable expenses incurred by such Agent-Related Person in connection with any dispute between such Agent-Related Person and any Lender or between two or more of the Lenders) and (iii) any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, reasonable costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against such Agent-Related Person in any way relating to or arising out of
the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against such Agent-Related Person in connection with any
dispute between such Agent-Related Person and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents. Without limitation of the foregoing, each Lender shall
reimburse each Agent and each Issuing Bank upon demand for its ratable share of any reasonable costs or out-of-pocket expenses (including Attorney Costs) incurred by such Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or
referred to herein, to the extent that 
  

 56 

 such Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in this Section shall
survive termination of the Commitments, this Agreement, the payment of all other Obligations and the resignation of such Agent. 
  
 SECTION 7.08. Agents in their Individual Capacities. Citicorp USA, Inc., Citibank, N.A., and JPMorgan Chase Bank, N.A. and their respective
Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with each of the Loan
Parties and their respective Affiliates as though Citicorp USA, Inc., Citibank, N.A., and JPMorgan Chase Bank, N.A. were not Agents hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities,
Citicorp USA, Inc., Citibank, N.A. and JPMorgan Chase Bank, N.A. or their respective Affiliates may receive information regarding any Loan Party or its Affiliates (including information that may be subject to confidentiality obligations in favor of
such Loan Party or such Affiliate) and acknowledge that no Agent shall be under any obligation to provide such information to them. 
  
 SECTION 7.09. Successor Agents. Any Agent may resign as Agent upon 30 days’ notice to the Lenders. If any Agent resigns under this Agreement,
the applicable Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be consented to by the Borrower at all times other than during the existence of an Event of Default (which consent of
the Borrower shall not be unreasonably withheld or delayed). If no successor agent is appointed prior to the effective date of the resignation of such Agent, such Agent may appoint, after consulting with the Lenders and the Borrower, a successor
agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, the Person acting as such successor agent shall succeed to all the rights, powers and duties of the retiring Agent and the terms “Administrative
Agent,” “Co-Administrative Agent” (if applicable) and “Collateral Agent” shall mean such successor administrative agent, co-administrative agent (if applicable) and collateral agent and the retiring Agent’s appointment,
powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Article VII and Sections 8.03 and 8.04 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was an Agent under this Agreement. If no successor agent has accepted appointment as Agent by the date which is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless
thereupon become effective and the Lenders shall perform all of the duties of such Agent hereunder until such time, if any, as the applicable Required Lenders appoint a successor agent as provided for above. Upon the acceptance of any appointment as
Agent hereunder by a successor and upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Collateral Documents, and such other instruments or notices, as may be
necessary or desirable, or as the applicable Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Agent shall thereupon succeed to and become
vested with all the rights, powers, discretion, privileges, and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under the Loan Documents. After any retiring Agent’s resignation hereunder
as an Agent, the provisions of this Article VII 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 an Agent. Any corporation or association into which either Collateral Agent
may be merged or converted or with which it may be consolidated, or any corporation or association to which all or substantially all the trust business of such Collateral 
  

 57 

 Agent’s corporate trust line of business may be transferred, shall be the successor of such Collateral Agent under
this Agreement without further act. 
  
 SECTION 7.10.
Administrative Agents May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Loan Party,
the Administrative Agents (irrespective of whether the principal of any Loan or Reimbursement Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agents shall
have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise: 
  
 (a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that
are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Agents allowed in such judicial proceeding; 
  
 (b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the
same; and 
  
 (c) any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agents and, in the event that the Administrative Agents shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agents any amount due for the reasonable compensation, expenses, disbursements and advances of the Agents and their respective agents and counsel, and any other amounts due the
Agents under Sections 2.10 and 8.03. 
  
 Nothing contained herein shall be deemed
to authorize the Administrative Agents to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the
Administrative Agents to vote in respect of the claim of any Lender in any such proceeding. 
  
 SECTION 7.11. Collateral and Guaranty Matters. (a) Provided that no Event of Default then exists, the Collateral Agents shall, and shall direct the Collateral Trustees to, release any Lien on any property
granted to or held by the Collateral Agents or the Collateral Trustees under any Loan Document (i) upon termination of the Commitments and payment in full of all Obligations (other than contingent indemnification obligations not yet accrued and
payable) and the expiration or termination of all Letters of Credit, (ii) that is disposed of as part of or in connection with any sale, lease, conveyance or other disposition (other than in respect of the Cash Collateral), or (iii) if
approved, authorized or ratified in writing by applicable Required Lenders. 
  
 (a) Provided that no Event of Default then exists, the Agents and the Collateral Agents shall, and shall direct the Collateral Trustees to, release any Loan Party from its obligations under the Loan Documents to which
it is a party or by which it is bound if such Person ceases to be a Subsidiary or is no longer required to be a party to the Guaranty as a result of a transaction permitted hereunder or otherwise in accordance with the terms of the Loan Documents.

  

 58 

 (b) The Collateral Agents and the Agents, as the case may be, will, at the Borrower’s expense,
timely execute and deliver such documents and notices and take such other actions as the Borrower may reasonably request to evidence the release of any Collateral or Loan Documents in accordance with this Section 7.11 and any other applicable
terms of the Loan Documents. 
  
 (c) Each Lender hereby authorizes
the Collateral Agents or the Administrative Agents to take the actions required under this Section 7.11. Without limiting such authorization, the requisite Lenders will timely confirm in writing the authority of the Collateral Agents or the
Administrative Agents, as applicable, with respect to any action under this Section 7.11. 
  
 SECTION 7.12. Other Agents; Arrangers and Bookrunners. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “co-agent,” “bookrunner,”
“lead manager,” “arranger,” “lead arranger” or “co-arranger” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than, in the case of such Lenders, those
applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and
will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder. 
  
 SECTION 7.13. Appointment of Supplemental Collateral Agents. It is the purpose of this Agreement and the other Loan Documents that there shall be
no violation of any law of any jurisdiction denying or restricting the right of banking corporations or associations to transact business as agent or trustee in such jurisdiction. It is recognized that in case of litigation under this Agreement or
any of the other Loan Documents, and in particular in case of the enforcement of any of the Loan Documents, or in case the Administrative Agents deem that by reason of any present or future law of any jurisdiction it may not exercise any of the
rights, powers or remedies granted herein or in any of the other Loan Documents or take any other action which may be desirable or necessary in connection therewith, it may be necessary that the Administrative Agents appoint an additional individual
or institution as a separate trustee, co-trustee, collateral agent, collateral sub-agent or collateral co-agent (any such additional individual or institution being referred to herein individually as a “Supplemental Collateral
Agent” and collectively as “Supplemental Collateral Agents”). 
  
 (a) In the event that the Administrative Agents appoint a Supplemental Collateral Agent with respect to any Collateral, (i) each and every right,
power, privilege or duty expressed or intended by this Agreement or any of the other Loan Documents to be exercised by or vested in or conveyed to the Administrative Agents with respect to such Collateral shall be exercisable by and vest in such
Supplemental Collateral Agent to the extent, and only to the extent, necessary to enable such Supplemental Collateral Agent to exercise such rights, powers and privileges with respect to such Collateral and to perform such duties with respect to
such Collateral, and every covenant and obligation contained in the Loan Documents and necessary to the exercise or performance thereof by such Supplemental Collateral Agent shall run to and be enforceable by either of the Administrative Agents or
such Supplemental Collateral Agents, and (ii) the provisions of this Article and of Section 8.03 that refer to the Administrative Agent shall inure to the benefit of such Supplemental Collateral Agent and all references therein to the
Agents shall be deemed to be references to the Administrative Agents and/or such Supplemental Collateral Agent, as the context may require. 
  

 59 

 (b) Should any instrument in writing from any Loan Party be required by any Supplemental Collateral Agent
so appointed by the Administrative Agents for more fully and certainly vesting in and confirming to him or it such rights, powers, privileges and duties, such Loan Party shall execute, acknowledge and deliver any and all such instruments promptly
upon request by the Administrative Agents. In case any Supplemental Collateral Agent, or a successor thereto, shall die, become incapable of acting, resign or be removed, all the rights, powers, privileges and duties of such Supplemental Collateral
Agent, to the extent permitted by law, shall vest in and be exercised by the Administrative Agents until the appointment of a new Supplemental Collateral Agent. 
  

ARTICLE VIII 
  
 GUARANTY 
  
 SECTION 8.01. Guaranty; Limitation of Liability. 
  
 (a) Each Guarantor, jointly and severally, hereby absolutely, unconditionally and irrevocably guarantees the punctual payment when due, whether at
scheduled maturity or on any date of a required prepayment or by acceleration, demand or otherwise, of all Obligations of the Borrower and of all ACH Obligations now or hereafter existing (including, without limitation, any extensions,
modifications, substitutions, amendments or renewals of any or all of the foregoing Obligations), whether direct or indirect, absolute or contingent, and whether for principal, interest, premiums, fees, indemnities, contract causes of action, costs,
expenses or otherwise (such Obligations being the “Guaranteed Obligations”), and agrees to pay any and all expenses (including, without limitation, fees and expenses of counsel) incurred by any Secured Party in enforcing any
rights under this Guaranty or any other Loan Document. Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by any other
Loan Party to any Secured Party under or in respect of the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party.

  
 (b) Each Guarantor, and by its acceptance of this Guaranty,
the Agents and each other Secured Party, hereby confirms that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of Debtor Relief
Laws, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guaranty and the Obligations of each Guarantor hereunder. To effectuate the foregoing
intention, the Agents, the other Secured Parties and the Guarantors hereby irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such
Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance. 
  

 60 

 (c) Each Subsidiary Guarantor hereby unconditionally and irrevocably agrees that in the event any payment
shall be required to be made to any Secured Party under this Guaranty, such Subsidiary Guarantor will contribute, to the maximum extent permitted by law, such amounts to each other Subsidiary Guarantor and each other Guarantor so as to maximize the
aggregate amount paid to the Secured Parties under or in respect of the Loan Documents. 
  
 SECTION 8.02. Guaranty Absolute. Each Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Loan Documents, regardless of any law, regulation or order
now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Secured Party with respect thereto. The Obligations of each Guarantor under or in respect of this Guaranty are independent of the Guaranteed Obligations
or any other Obligations of any other Loan Party under or in respect of the Loan Documents, and a separate action or actions may be brought and prosecuted against each Guarantor to enforce this Guaranty, irrespective of whether any action is brought
against the Borrower or any other Loan Party or whether the Borrower or any other Loan Party is joined in any such action or actions. The liability of each Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective
of, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to, any or all of the following: 
  
 (a) any lack of validity or enforceability of any Loan Document or any agreement or instrument relating thereto; 
  
 (b) any change in the time, manner or place of payment of, or in any other
term of, all or any of the Guaranteed Obligations or any other Obligations of any other Loan Party under or in respect of the Loan Documents, or any other amendment or waiver of or any consent to departure from any Loan Document, including, without
limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to any Loan Party or any of its Subsidiaries or otherwise; 
  
 (c) any taking, exchange, release or non-perfection of any Collateral or any other collateral, or any taking, release or
amendment or waiver of, or consent to departure from, any other guaranty, for all or any of the Guaranteed Obligations; 
  
 (d) any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of
sale or other disposition of any Collateral or any other collateral for all or any of the Guaranteed Obligations or any other Obligations of any Loan Party under the Loan Documents or any other assets of any Loan Party or any of its Subsidiaries;

  
 (e) any change, restructuring or termination of the corporate
structure or existence of any Loan Party or any of its Subsidiaries; 
  
 (f) any failure of any Secured Party to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known
to such Secured Party (each Guarantor waiving any duty on the part of the Secured Parties to disclose such information); 
  

 61 

 (g) the failure of any other Person to execute or deliver this Guaranty or any other guaranty or
agreement or the release or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guaranteed Obligations; or 
  
 (h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by any
Secured Party that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety. 
  
 This Guaranty shall survive termination of this Agreement and shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of
the Guaranteed Obligations is rescinded or must otherwise be returned by any Secured Party or any other Person upon the insolvency, bankruptcy or reorganization of the Borrower or any other Loan Party or otherwise, all as though such payment had not
been made. 
  
 SECTION 8.03. Waivers and Acknowledgments.

  
 (a) Each Guarantor hereby unconditionally and irrevocably
waives promptness, diligence, notice of acceptance, presentment, demand for performance, notice of nonperformance, default, acceleration, protest or dishonor and any other notice with respect to any of the Guaranteed Obligations and this Guaranty
and any requirement that any Secured Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against any Loan Party or any other Person or any Collateral. 
  
 (b) Each Guarantor hereby unconditionally and irrevocably waives any right to
revoke this Guaranty and acknowledges that this Guaranty is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future. 
  
 (c) Each Guarantor hereby unconditionally and irrevocably waives (i) any defense arising by reason of any claim or
defense based upon an election of remedies by any Secured Party that in any manner impairs, reduces, releases or otherwise adversely affects the subrogation, reimbursement, exoneration, contribution or indemnification rights of such Guarantor or
other rights of such Guarantor to proceed against any of the other Loan Parties, any other guarantor or any other Person or any Collateral and (ii) any defense based on any right of set-off or counterclaim against or in respect of the
Obligations of such Guarantor hereunder. 
  
 (d) Each Guarantor
acknowledges that the Collateral Agents may, without notice to or demand upon such Guarantor and without affecting the liability of such Guarantor under this Guaranty, foreclose under any mortgage by nonjudicial sale, and each Guarantor hereby
waives any defense to the recovery by any Collateral Agent and the other Secured Parties against such Guarantor of any deficiency after such nonjudicial sale and any defense or benefits that may be afforded by applicable law. 
  
 (e) Each Guarantor hereby unconditionally and irrevocably waives any duty on
the part of any Secured Party to disclose to such Guarantor any matter, fact or thing relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party or any of its Subsidiaries
now or hereafter known by such Secured Party. 
  

 62 

 (f) Each Guarantor acknowledges that it will receive substantial direct and indirect benefits from the
financing arrangements contemplated by the Loan Documents and that the waivers set forth in Section 8.02 and this Section 8.03 are knowingly made in contemplation of such benefits. 
  
 SECTION 8.04. Subrogation. Each Guarantor hereby unconditionally and
irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against the Borrower, any other Loan Party or any other insider guarantor that arise from the existence, payment, performance or enforcement of such
Guarantor’s Obligations under or in respect of this Guaranty or any other Loan Document, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any
claim or remedy of any Secured Party against the Borrower, any other Loan Party or any other insider guarantor or any Collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including,
without limitation, the right to take or receive from the Borrower, any other Loan Party or any other insider guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such
claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash, all Letters of Credit shall have expired or been terminated and the Commitments shall
have expired or been terminated. If any amount shall be paid to any Guarantor in violation of the immediately preceding sentence at any time prior to the latest of (a) the payment in full in cash of the Guaranteed Obligations and all other
amounts payable under this Guaranty, (b) the latest maturity date in respect of the Facilities outstanding from time to time and (c) the latest date of expiration or termination of all Letters of Credit, such amount shall be received and
held in trust for the benefit of the Secured Parties, shall be segregated from other property and funds of such Guarantor and shall forthwith be paid or delivered to the Payment Agent in the same form as so received (with any necessary endorsement
or assignment) to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the Loan Documents, or to be held as Collateral for any
Guaranteed Obligations or other amounts payable under this Guaranty thereafter arising. If (i) any Guarantor shall make payment to any Secured Party of all or any part of the Guaranteed Obligations, (ii) all of the Guaranteed Obligations
and all other amounts payable under this Guaranty shall have been paid in full in cash, (iii) the latest maturity date in respect of the Facilities outstanding from time to time shall have occurred and (iv) all Letters of Credit shall have
expired or been terminated, the Secured Parties will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the
transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment made by such Guarantor pursuant to this Guaranty. 
  
 SECTION 8.05. Subordination. Each Guarantor hereby subordinates any and all debts, liabilities and other obligations
owed to such Guarantor by each other Loan Party (the “Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner hereinafter set forth in this Section 8.06: 
  
 (a) Prohibited Payments, Etc. Except during the continuance of a
Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), each Guarantor may receive payments from any other Loan 
  

 63 

 Party on account of the Subordinated Obligations. After the occurrence and during the continuance of any Default
(including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), however, unless the Required Lenders otherwise agree, no Guarantor shall demand, accept or take any action to collect any
payment on account of the Subordinated Obligations. 
  
 (b)
Prior Payment of Guaranteed Obligations. In any proceeding under any Debtor Relief Law relating to any other Loan Party, each Guarantor agrees that the Secured Parties shall be entitled to receive payment in full in cash of all Guaranteed
Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Debtor Relief Law, whether or not constituting an allowed claim in such proceeding (“Post-Petition Interest”)) before
such Guarantor receives payment of any Subordinated Obligations. 
  
 (c) Turn-Over. After the occurrence and during the continuance of any Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), each Guarantor shall, if the
Administrative Agents so request, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for the Secured Parties and deliver such payments to the Payment Agent on account of the Guaranteed Obligations (including
all Post-Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Guaranty. 
  
 (d) Administrative Agents Authorization. After the occurrence and
during the continuance of any Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any other Loan Party), the Administrative Agents are authorized and empowered (but without any obligation to
so do), in its discretion, (i) in the name of each Guarantor, to collect and enforce, and to submit claims in respect of, Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all
Post-Petition Interest), and (ii) to require each Guarantor (A) to collect and enforce, and to submit claims in respect of, Subordinated Obligations and (B) to pay any amounts received on such obligations to the Administrative Agents
for application to the Guaranteed Obligations (including any and all Post-Petition Interest). 
  
 SECTION 8.06. Continuing Guaranty; Assignments. This Guaranty is a continuing guaranty and shall (a) remain in full force and effect until the latest of (i) the payment in full in cash of the
Guaranteed Obligations and all other amounts payable under this Guaranty, (ii) the latest maturity date in respect of the Facilities outstanding from time to time and (iii) the latest date of expiration or termination of all Letters of
Credit, (b) be binding upon the Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Secured Parties and their successors, transferees and assigns. Upon the occurrence of the latest date specified
in clause (a) above, the Guarantors shall be released from other Obligations under the Loan Documents. Without limiting the generality of clause (c) of the immediately preceding sentence, any Secured Party may assign or otherwise transfer
all or any portion of its rights and obligations under this Agreement to any other Person, and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such Secured Party herein or otherwise, in each case
as and to the extent provided in this Section 8.06. No Guarantor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Secured Parties.

 SECTION 9.02. Waivers; Amendments. 
  
 (a) No Deemed Waivers; Remedies Cumulative. No failure or delay by
the Administrative Agents, the Issuing Banks or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of
steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agents, the Issuing Banks and the Lenders hereunder are cumulative and
are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, 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 issuance of any Letter of Credit shall
not be construed as a waiver of any Default, regardless of whether the Administrative Agents, any Lender or the Issuing Banks may have had notice or knowledge of such Default at the time. 
  
 (b) Amendments. Subject to Section 7.01(e), neither this Agreement nor any provision hereof may be
waived, amended or modified except pursuant to an agreement or agreements in writing entered into (x) by the Borrower and the LC Required Lenders or by the Borrower and the Co-Administrative Agents with the consent of the LC Required Lenders
(with respect to any provision hereof or any other Loan Document related to or affecting the rights, remedies or duties of any LC Lender or the obligations of any Loan Party with respect to any Letter of Credit or LC Commitment) and (y) by the
Borrower and the Revolving Loan Required Lenders or by the Borrower and the Revolving Loan Administrative Agent with the consent of the Revolving Loan Required Lenders (with respect to any provision hereof or any other Loan Document related to or
affecting the rights, remedies or duties of any Revolving Loan Lender or the obligations of any Loan Party with respect to any Revolving Loan or Revolving Loan Commitment); provided that no such agreement shall: 
  
 (i) increase the Commitment of any Lender without the
written consent of such Lender; 
  

 67 

 (ii) reduce the principal amount of any LC Disbursement or Revolving Loan or reduce
the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby; 
  
 (iii) postpone the scheduled date of payment of the principal amount of any LC Disbursement or Revolving Loan, or any interest
thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, without the written consent of each Lender affected thereby; 
  

(iv) change Section 2.13(d) without the consent of the Issuing Banks and each Lender affected thereby; 
  
 (v) change any of the provisions of this Section or the
percentage in the definition of the term “LC Required Lenders” or any other provision hereof specifying the number or percentage of LC Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any
consent hereunder, without the written consent of each LC Lender, or change any of the provisions of this Section or the percentage in the definition of the term “Revolving Loan Required Lenders” or “Pro Rata Share” or any other
provision hereof specifying the number or percentage of Revolving Loan Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Revolving Loan
Lender; 
  
 (vi) release the LC Cash Collateral
and amounts in the LC Cash Collateral Account (other than as permitted by the Loan Documents) without the written consent of the Issuing Banks and each LC Lender; 
  
 (vii) release the Revolving Loan Cash Collateral and amounts in the Revolving Loan Cash Collateral Account
(other than as permitted by the Loan Documents) without the written consent of each Revolving Loan Lender; and 
  
 (viii) release all or substantially all of the collateral (excluding the Cash Collateral and amounts in the Cash Collateral Account) under
the Collateral Documents (other than as permitted by Section 7.11 and the Loan Documents) without the written consent of the Issuing Banks and each Lender affected thereby; 
  
 provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agents,
the Collateral Agents or the Issuing Banks hereunder without the prior written consent of the Administrative Agents, the Collateral Agents or the Issuing Banks, as the case may be. 
  
 SECTION 9.03. Expenses; Indemnity; Damage Waiver. 
  
 (a) Costs and Expenses. The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Issuing
Banks, their Affiliates and the Lenders, including the reasonable fees, charges and disbursements of counsel for the Issuing Banks and the Lenders, in connection with the syndication of the credit facilities provided for herein, the preparation and
administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions 
  

 68 

 contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the
Issuing Banks and the LC Lenders in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, the fees and expenses of the Collateral Agents and the Depositary Banks as separately
agreed, (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agents, the Issuing Banks or any Lender, including the fees, charges and disbursements of a single counsel for the Administrative Agents, the Issuing Banks and
the Lenders, in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents, including its rights under this Section, or in connection with any Letter of Credit issued hereunder,
including in connection with any workout, restructuring or negotiations in respect thereof and (iv) and all costs, expenses, taxes, assessments and other charges incurred in connection with any filing, registration, recording or perfection of
any security interest contemplated by the Cash Collateral Account Agreements or any other document referred to therein. 
  
 (b) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agents, the Collateral Agents, the Issuing Banks and each
Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related
expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or
any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) the issuance,
amendment, renewal or extension of any Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Banks to honor a demand for payment under that Letter of Credit if the documents presented in connection with such
demand do not strictly comply with the terms of such Letter of Credit), or (iii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing; provided that such indemnity shall not, as to any
Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Indemnitee. 
  
 (c) Reimbursement by
Lenders. To the extent that the Borrower fails to pay any amount required to be paid by it to the Co-Administrative Agents, the Issuing Banks or the LC Collateral Agent under paragraph (a) or (b) of this Section, each LC Lender agrees
to pay to the Co-Administrative Agents, the Issuing Banks or the LC Collateral Agent, as applicable, such LC Lender’s ratable share of the LC Exposure (determined as of the time that the applicable unreimbursed expense or indemnity payment is
sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Co-Administrative Agents, the Issuing Banks or
the LC Collateral Agent in their capacity as such. To the extent that the Borrower fails to pay any amount required to be paid by it to the Revolving Loan Administrative Agent or the Revolving Loan Collateral Agent under paragraph (a)
or (b) of this Section, each Revolving Loan Lender agrees to pay to the Revolving Loan Administrative Agent or the Revolving Loan Collateral Agent, as applicable, such Revolving Loan Lender’s ratable share of the Revolving Loan Obligations
(determined as of the time that the applicable unreimbursed expense or 
  

 69 

 indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss,
claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Revolving Loan Administrative Agent or the Revolving Loan Collateral Agent in their capacity as such. 
  
 (d) Waiver of Consequential Damages, Etc. To the extent permitted by
applicable law, the Borrower shall not assert, and the Borrower hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising
out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Cash Collateral Account Agreements, any Letter of Credit, any Revolving Loan or the use of the proceeds thereof. 
  
 (e) Payments. All amounts due under this Section shall be payable
promptly after written demand therefor. 
  
 SECTION 9.04.
Successors and Assigns. 
  
 (a) Assignments
Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of
its rights or obligations hereunder (other than as permitted by Section 5.02(b)) without the prior written consent of the Issuing Banks and each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null
and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the
Related Parties of each of the Administrative Agents, the Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
  
 (b) Assignments by Lenders. Any Lender may assign to one or more assignees all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment); provided that 
  
 (i) except in the case of an assignment to a Lender or an Affiliate of a Lender: (x) in the case of an assignment of any LC
Commitment, LC Loan or any LC Exposure, each of the Borrower, the Issuing Banks and the Co-Administrative Agents and (y) in the case of an assignment of Revolving Loans or Revolving Loan Commitments, each of the Borrower and the Revolving Loan
Administrative Agent must in each case give their prior written consent to such assignment (which consent shall not be unreasonably withheld), 
  
 (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the
assigning Lender’s Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the applicable
Administrative Agents) shall not be less than $5,000,000 unless each of the Borrower and the applicable Administrative Agents otherwise consent, 
  

 70 

 (iii) each partial assignment shall be made as an assignment of a proportionate part of

further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default under clause (a) or (d) of Article VI has occurred and is continuing. Upon acceptance and recording
pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and
Acceptance, have the rights and obligations of a Lender (either an LC Lender or a Revolving Loan Lender, as applicable) under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto
but shall continue to be entitled to the benefits of Sections 2.11, 2.12 and 8.03, but only to the extent relating to or in respect of periods prior to the effective date of such Assignment and Acceptance). Any assignment or transfer by a
Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with
paragraph (e) of this Section. 
  
 (c) Maintenance of
Register by the Payment Agent. The Payment Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in New York City a copy of each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of LC Disbursements and Revolving Loans owing to, each Lender pursuant to the terms hereof from time to time (the
“Register”). The entries in the Register shall be conclusive, and the Borrower, the Payment Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as
a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Banks and any Lender, at any reasonable time and from time to time upon
reasonable prior notice. 
  
 (d) Effectiveness of
Assignments. Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such
assignment required by paragraph (b) of this Section, the Payment Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement
unless it has been recorded in the Register as provided in this paragraph. 
  

 71 

 (e) Participations. Any Lender may, without the consent of the Borrower, the Administrative Agents
or the Issuing Banks, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement and the other Loan Documents (including
all or a portion of its Commitment and the LC Disbursements and Revolving Loans owing to it); provided that (i) such Lender’s obligations under this Agreement and the other Loan Documents shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agents, the Issuing Banks and the other Lenders shall continue to deal solely and directly
with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall
retain the sole right to enforce this Agreement and the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement or any other Loan Document; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 8.02(b) that affects such Participant. Subject to paragraph (f) of this
Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.11 and 2.12 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. 
  
 (f) Limitations on Rights of Participants. A
Participant shall not be entitled to receive any greater payment under Section 2.11 or 2.12 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the
participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.12 unless the Borrower is notified of
the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.12(e) as though it were a Lender. 
  
 (g) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its
rights under this Agreement to secure obligations of such Lender, including any such pledge or assignment to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no
such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto. 
  
 (h) No Assignments to the Obligors or Affiliates. Anything in this Section to the contrary notwithstanding, neither
the Issuing Banks nor any Lender may assign or participate any interest in any LC Exposure, Revolving Loan or Revolving Loan Commitment held by it hereunder to the Borrower or any of its Affiliates or Subsidiaries without the prior consent of
the Issuing Banks and each Lender. 
  
 SECTION 9.05.
Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied
upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the issuance of any Letter of Credit and making of any Revolving Loan, regardless of any investigation made by any such other party or on its behalf
and notwithstanding that the 
  

 72 

 Administrative Agents, the Issuing Banks or any Lender may have had notice or knowledge of any Default or incorrect
representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as any amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as
the Commitments have not expired or terminated. The provisions of Sections 2.11, 2.12 and 8.03 and Article VII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the
repayment of the obligations hereunder, the expiration or termination of the Letter of Credit and the Commitments or the termination of this Agreement or any provision hereof. 
  
 SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by
different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement the related Loan Documents and any separate letter agreements
with respect to fees payable to the Agents constitute the entire contract between and among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject
matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agents and when the Administrative Agents shall have received counterparts hereof which, when taken
together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature
page to this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 
  
 SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a
particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
  
 SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, the Issuing Banks and each Lender is hereby authorized at any time and from time to time, to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Issuing Banks or Lender to or for the credit or the account of
the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by the Issuing Banks or Lender, irrespective of whether or not the Issuing Banks or Lender shall have made any demand under this
Agreement and although such obligations may be unmatured. The rights of the Issuing Banks and each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which the Issuing Banks or Lender may have.

  
 SECTION 9.09. Governing Law; Jurisdiction; Etc.

  
 (a) Governing Law. This Agreement shall be governed
by, and construed in accordance with, the law of the State of New York applicable to contracts made and performed in the State of New York. 
  

 73 

 (b) Submission to Jurisdiction; Waiver of Venue. The Borrower submits to the nonexclusive
jurisdiction of the United States District Court of the Southern District of New York and of any New York State court sitting in New York for the purposes of all legal proceedings arising out of or relating to this Agreement or the Transactions
contemplated by this Agreement. Each Party irrevocably waives, to the fullest extent permitted by applicable law, any objection that it may not or in the future have to the laying of the venue of any such proceeding brought in any such court and any
claim that any such proceeding brought in any such court has been brought in an inconvenient forum. 
  
 (c) Service of Process. Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in
Section 8.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
  
 SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
  
 SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of
this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 
  
 SECTION 9.12. Treatment of Certain Information; Confidentiality. 
  
 (a) Treatment of Certain Information. The Borrower acknowledges that from time to time financial advisory, investment
banking and other services may be offered or provided to the Borrower or one or more of its Subsidiaries (in connection with this Agreement or otherwise) by the Issuing Banks, any Lender or by one or more Subsidiaries or Affiliates of the Issuing
Banks or Lender and the Borrower hereby authorizes the Issuing Banks and each Lender to share any information delivered to the Issuing Banks and Lender by the Borrower and its Subsidiaries pursuant to this Agreement, or in connection with the
decision of the Issuing Banks or Lender to enter into this Agreement, to any such Subsidiary or Affiliate, it being understood that any such Subsidiary or Affiliate receiving such information shall be bound by the provisions of paragraph (b) of
this Section as if it were the Issuing Banks or a Lender hereunder. Such authorization shall survive the payment of the obligations hereunder, the expiration or termination of the Letter of Credit and the Commitments or the termination of this
Agreement or any provision hereof. 
  
 (b) Confidentiality.
Each of the Administrative Agents, the Issuing Banks and the Lenders agrees to use reasonable precautions to keep confidential, in accordance with its customary procedures for its own confidential information, any nonpublic information supplied to
it by the Borrower pursuant to this Agreement that is identified by the Borrower as confidential at the time it is delivered to the any Administrative Agent, the Issuing Banks or any Lender; provided that nothing in this Agreement shall limit
the disclosure of any such information (i) to the extent required by Governmental Rule, (ii) to counsel to the Administrative Agents, the Issuing Banks or any the Lender, (iii) to bank examiners, auditors or accountants, 

 

 74 

 (iv) to any other party to this Agreement or any Affiliate of that party, (v) in connection with any litigation
to which any one or more of the parties to this Agreement is a party, (vi) to any assignee or participant (or prospective assignee or participant) of any Lender so long as that assignee or participant (or prospective assignee or participant)
first executes and delivers to such Lender an agreement substantially to the same effect as this Section 8.12(b), (vii) to the extent that such information becomes publicly available (other than as a result of a breach of this
Section 8.12(b)) or is received from a source other than the Borrower or (viii) with the consent of the Borrower. 
  

 75
