with the Transactions, at least 15% (the “Minimum Equity Amount”) of the total sources (including the Existing Notes, the Existing Parent Notes and the Existing Oncor Notes, but excluding any transition bonds) required to consummate
the Merger (the “Merger Consideration”), to redeem, refinance or repay certain existing indebtedness or repurchase receivables of the Parent and its Subsidiaries, including the Repaid Indebtedness (the

(c) $1,250,000,000 in aggregate principal amount of Deposit L/C Loans to be borrowed on the Closing Date (the “Deposit L/C Loan Facility”) and (d) up to $2,700,000,000 in

respect of the Borrower), each Revolving Credit Lender hereby agrees that it shall forthwith purchase from the Swingline Lender (without recourse or warranty) such participation of the outstanding Swingline Loans as shall be necessary to cause each

Original Swingline Maturity Date, the interests and participations of the 2013 Revolving Lenders in the Swingline Loans (if any) outstanding as at such day shall automatically terminate at the close of business on such date and such interests and
participations in outstanding Swingline Loans shall thereupon automatically and without further action be re-allocated to the extent necessary such that the interests and participations in such Swingline Loans shall be held by the 2016 Revolving
Credit Lenders ratably in proportion to their respective 2016 Revolving Credit Commitments. If the reallocations described in the previous sentence cannot, or can only partially, be effected as a result of the limitations set forth herein, the
Borrower shall, on the Original Swingline Maturity Date, prepay Swingline Loans in an amount necessary such that after giving effect to such prepayment the reallocations described in the previous sentence can be fully effected and the sum of the

Lender shall succeed to the rights, powers and duties of the replaced or resigning Swingline Lender under this Agreement and the other Credit Documents, and the term “Swingline Lender” shall mean such successor or such new Swingline Lender
effective upon such appointment. The acceptance of any appointment as a Swingline Lender hereunder shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the Borrower and the Administrative Agent. If the
Swingline Lender resigns as Swingline Lender, it shall retain all rights of the Swingline Lender provided for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to
require the Lenders to make Revolving Credit Loans and fund risk participations in outstanding Swingline Loans.

Lender may at its option make any LIBOR Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that (A) any exercise of such option shall not affect the obligation of the Borrower to repay
such Loan and (B) in exercising such option, such Lender shall use its reasonable efforts to minimize any increased costs to the Borrower resulting therefrom (which obligation of the Lender shall not require it to take, or refrain from taking,
actions that it determines would result in increased costs for which it will not be compensated hereunder or that it determines would be otherwise disadvantageous to it and in the event of such request for costs for which compensation is provided
under this Agreement, the provisions of Section 2.10 shall apply).

the relevant Lenders thereof. Each such determination shall, absent clearly demonstrable error, be final and conclusive and binding on all parties hereto. 
 (h) The Posting Agent, upon determining the LIBOR Rate for each Posting Interest Period, shall promptly notify the Borrower and the Posting Calculation Agent of such determination by no later than 10:00

#4812-2844-92899582-0297 
 -108- 

 
would have led to the application of a higher Applicable ABR Margin or Applicable LIBOR Margin for any period (an “Applicable Period”) than the Applicable ABR Margin or

is negative, the Administrative Agent shall deliver notice to the Borrower of such Shortfall Amount and, within 10 Business Days of receipt of such notice, the Borrower shall pay to the Administrative Agent an amount equal to such Shortfall Amount
(each such payment under clause (i) or (ii), a “Shortfall Payment”); provided that (A) in no event shall the Borrower be obligated to make Shortfall Payments to the Administrative Agent that, in the
aggregate, exceed the greater of (x) the aggregate amount of Shortfall Payments made by the Administrative Agent to the Borrower from the Closing Date through any such date of determination and (y) the Upside Amount as of the date of such
determination (each such payment made pursuant to this clause (y) in excess of the amount in clause (x), an “Upside Amount Payment”) and (B) for the avoidance of doubt, (1) the Administrative Agent shall have no
obligation to make Shortfall Payments to the Borrower with respect to amounts accrued (or that would have accrued) after the 2014 Deposit L/C Loan Maturity Date and (2) the Borrower shall have no obligation to make Shortfall Payments to the
Administrative Agent with respect to amounts accrued (or that would have accrued) after the 2014 Deposit L/C Loan Maturity Date.

#4812-2844-92899582-0297 
 -109-

 (a) In the event that (x) in the case of clause (i) below, the
Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) or (y) in the case of clauses (ii) and (iii) below, any Lender shall have reasonably determined (which determination shall, absent clearly
demonstrable error, be final and conclusive and binding upon all parties hereto):

 (iii) at any time, that the making or
continuance of any LIBOR Loan or the making of any Posting Advance has become unlawful as a result of compliance by such Lender in good faith with any Applicable Law (or would conflict with any such Applicable Law not having the force of law even
though the failure to comply therewith would not be unlawful), or has become impracticable as a result of a contingency occurring after the date hereofClosing Date that materially and adversely affects the interbank LIBOR
market;

the Administrative Agent (or the Posting Agent, as applicable) no longer exist (which notice the Administrative Agent (or the Posting Agent, as applicable) agrees to give at such time when such circumstances no longer exist), and any Notice of
Borrowing or Notice of Conversion given by the Borrower with respect to LIBOR Loans or any notice given by the Posting Calculation Agent with respect to any Posting Advances, that have not yet been incurred shall be deemed rescinded by the Borrower

(it being agreed that a written notice as to the additional amounts owed to such Lender, showing in reasonable detail the basis for the calculation thereof, submitted to the Borrower by such Lender shall, absent clearly demonstrable error, be final
and conclusive and binding upon all parties hereto) and (z) in the case of subclause (iii) above, the Borrower shall take one of the actions specified in Section 2.10(b) as promptly as possible and, in any event, within
the time period required by Applicable Law. 
 (b) At any time that any LIBOR Loan or any Posting Advance is affected by the
circumstances described in Section 2.10(a)(ii) or (iii), the Borrower may (and in the case of a LIBOR Loan or a Posting Advance, as the case may be, affected pursuant to Section 2.10(a)(iii) shall) either (x) if

promptly in writing) thereof on the same date that the Borrower was notified by a Lender pursuant to Section 2.10(a)(ii) or (iii) or (y) if the affected LIBOR Loan or the affected Posting Advance, as the case may be, is
then -outstanding, upon at least three Business Days’ notice to the Administrative Agent (or the Posting Agent, as applicable) require the affected Lender to convert each such LIBOR Loan or such Posting Advance, as the case may be, into
an ABR Loan; provided that if more than one Lender is affected at any time, then all affected Lenders must be treated in the same manner pursuant to this Section 2.10(b). 

(c) If, after the date hereofClosing Date, any Change in Law relating to capital adequacy of any Lender or
compliance by any Lender or its parent with any Change in Law relating to capital adequacy occurring after the date hereofClosing Date, has or would have the effect of reducing the rate of return on such Lender’s or its
parent’s or its Affiliate’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent or its Affiliate could have achieved but for such Change in Law
(taking into consideration such Lender’s or its parent’s policies with respect to capital adequacy), then from time to time, promptly after demand by such Lender (with a copy to the Administrative Agent (or with respect to the Posting
Facility, the Posting Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or its parent for such reduction, it being understood and agreed, however, that a Lender shall not be entitled to
such compensation as a result of such Lender’s compliance with, or pursuant to any request or directive to comply with, any Applicable Law as in effect on the date hereofClosing Date. Each Lender, upon determining in
good faith that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to the Borrower, which notice shall set forth in reasonable detail the basis

  

#4812-2844-92899582-0297 
 -111- 

 
of the calculation of such additional amounts, although the failure to give any such notice shall not, subject to Section 2.13, release or diminish the Borrower’s obligations to

efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Loans or any Posting Advances affected by such event; provided that such designation is made on such terms that such Lender and its
lending office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section 2.12 shall affect or postpone any of

Deposit L/C Loans, (ii) shall not mature earlier than the Deposit L/C LoanLatest Maturity Date, (iii) shall have interest rates, interest margins, rate floors, fees, funding discounts, premiums and
amortization schedules determined by the Borrower and the lenders thereof and (iv) may have terms and conditions different from those of the other Deposit L/C Loans; provided that, except with respect to the differences set forth
in clauses (ii) and (iii) above, any differences must be reasonably acceptable to the Administrative Agent. 
 (e) Each Incremental Posting Facility shall rank pari passu in right of payment and of security with the Revolving Credit Loans, the Initial Term Loans, the Delayed Draw Term
Loans, theall other Posting Advances and the Deposit L/C Loans. 
 (f) Each notice from the Borrower pursuant to
this Section 2.14 shall set forth the requested amount and proposed terms of the relevant Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving Commitment Increases or Incremental Posting Facilities. Incremental
Term Loans and Incremental Deposit L/C Loans may be made, and Incremental

Revolving Commitment Increases and Incremental Posting Facilities may be provided, by any existing Lender (it being understood that (i) no existing Lender will have an obligation to make a
portion of any Incremental Term Loan, Incremental Deposit L/C Loan or any Incremental Posting Facility, (ii) no existing Lender with a Revolving Credit Commitment will have any obligation to provide a portion of any Incremental Revolving
Commitment Increase and (iii) the Borrower shall have no obligation to offer any existing Lender the opportunity to provide any such Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving
CreditCommitment Increases (including pursuant to New Revolving Credit Commitments) or Incremental Posting Facilities) or by any other bank or other financial institution (any such other bank or other financial
institution being called an “Additional Lender”); provided that the Administrative Agent shall have consented (not to be unreasonably withheld) to such Lender’s or Additional Lender’s making such
Incremental Term Loans, Incremental Deposit L/C Loans or providing such Incremental Revolving Commitment Increases if such consent would be required under Section 13.6(b) for an assignment of Loans or Commitments, as applicable, to such
Lender or Additional Lender. 
 (g) Commitments in respect of Incremental Term Loans, Incremental Deposit L/C Loans, Incremental
Revolving Commitment Increases and Incremental Posting Facilities shall become Commitments (or in the case of an Incremental Revolving Commitment Increase to be provided by an existing Lender with a Revolving Credit Commitment, an increase in such
Lender’s applicable Revolving Credit Commitment) under this Agreement pursuant to an amendment (an “Incremental Amendment”) to this Agreement (which shall be substantially in the form of Exhibit L to this Agreement) and,
as appropriate, the other Credit Documents, executed by the Borrower, each Lender agreeing to provide such Commitment, if any, each Additional Lender, if any, except with respect to any Incremental Posting Facility, the Administrative Agent and,
with respect to any Incremental Posting Facility, the relevant posting and calculation agents. The Incremental Amendment may, subject to Section 2.14(c), (d) or (e) as the case may be, without the consent of any
other Lenders, effect such amendments to this Agreement and the other Credit Documents as may be necessary, in the reasonable opinion of the Administrative Agent and the Borrower, to effect the provisions of this Section. The effectiveness of any
Incremental Amendment shall be subject to the satisfaction on the date hereofthereof (each an “Incremental Facility Closing Date”) of the conditions in Section 7.1 and such other conditions as the
parties thereto shall agree. The Borrower may use the proceeds of the Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving Commitment Increases and Incremental Posting Facilities for any purpose not prohibited by this
Agreement. 
 (h) (i) No Lender shall be obligated to provide any Incremental Term Loans, Incremental Deposit L/C Loans,
Incremental Revolving Commitment Increases or Incremental Posting Facilities, unless it so agrees and the Borrower shall not be obligated to offer any existing Lender the opportunity to provide any Incremental Term Loans, Incremental Deposit L/C
Loans, Incremental Revolving Credit Increases or Incremental Posting Facilities. Upon each increase in the Revolving Credit Commitments or, after the 2011 Revolving Credit Commitment Extension Effective Date, the 2016 Revolving Credit Commitments
or any other Extended Revolving Credit Commitment (other than pursuant to clause (ii) below) pursuant to this Section, each Lender with a Revolving Credit Commitment immediately prior to such increase will automatically and without further
act be deemed to have assigned to each Lender providing a portion of the Incremental Revolving Commitment Increase (each an “Incremental Revolving Commitment Increase Lender”) in respect of such increase, and each such Incremental
Revolving Commitment Increase Lender will automatically and without further act be deemed to have assumed, a portion of such Lender’s participations hereunder in outstanding Revolving Letters of Credit and Swingline Loans such that, after
giving effect to each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding (i) participations hereunder in Revolving Letters of Credit and (ii) participations hereunder in Swingline Loans
held by each Lender with a Revolving Credit Commitment (including each such Incremental Revolving Commitment Increase Lender) will equal the percentage of the aggregate Revolving Credit Commitments of all Lenders represented by such Lender’s
Revolving Credit Commitment. If, on the date of such increase, there are any Revolving Credit Loans outstanding, such Revolving Credit Loans shall on or prior to the effectiveness of such Incremental Revolving Commitment Increase be prepaid from the
proceeds of additional Revolving Credit Loans made 

  

#4812-2844-92899582-0297 
 -114- 

 
hereunder (reflecting such increase in Revolving Credit Commitments), which prepayment shall be accompanied by accrued interest on the Revolving Credit Loans being prepaid and any costs incurred
by any Lender in accordance with Section 2.11. The Administrative Agent and the Lenders hereby agree that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in this Agreement
shall not apply to the transactions effected pursuant to the immediately preceding sentence. 
 (ii) At the option of the
Borrower and the Incremental Lenders providing such Incremental Revolving Commitment Increases, any Incremental Revolving Commitment Increases may be in the form of one or more separate classes of revolving credit commitments (the
“New Revolving Credit Commitments”) which shall constitute a separate Class of Commitments from the Revolving Credit Commitments, any other Extended Revolving Credit Commitments and/or any other New Revolving Credit
Commitments (each such separate Class of New Revolving Credit Commitments, a “New Revolving Credit Series” and each Loan thereunder, a “New Revolving Credit Loan”) and the related Loans
shall constitute a separate Class of Loans from the Revolving Credit Loans, any other Extended Revolving Credit Loans and/or any other New Revolving Credit Loans (it being understood that New Revolving Credit Commitments of a single New Revolving
Credit Series may be established on more than one date); provided that: 
 (A) the aggregate amount
of New Revolving Credit Commitments in effect at any time, when aggregated with the aggregate amount of Revolving Credit Commitments and any other Extended Revolving Credit Commitments at such time, shall not exceed the sum of
(x) $2,700,000,000 less all 2011 Revolving Credit Commitment Termination Amounts and (y) the remainder, if positive, of (A) $750,000,000 minus (B) the aggregate amount of Incremental Term Loans and Incremental Deposit L/C Loans
established on or prior to such date minus (C) the aggregate amount of Permitted Other Debt previously established in reliance of Section 10.1(y)(iii); 
 (B) Each tranche of New Revolving Credit Commitments shall be in an aggregate principal amount of not less than $50,000,000 (provided that such amount may be less than $50,000,000 if such amount
represents all remaining availability under the limit set forth in Section 2.14(b) above). 

(C) the terms of such New Revolving Credit Commitments, except for (w) the tenor of the New Revolving
Credit Commitments (which shall have a scheduled expiration date no earlier than the Revolving Credit Maturity Date), (x) the size of any swingline loan and/or letter of credit subfacilities under such New Revolving Credit Commitments,
(y) the applicable interest rates, interest margins, rate floors, premiums, funding discounts and fees payable with respect to such New Revolving Credit Commitments and (z) the borrowing, repayment and termination of Commitment procedures
(in each case which shall be as specified in the applicable Incremental Amendment), shall be similar to the terms of the Revolving Credit Commitments and any other Extended Revolving Credit Commitments (unless otherwise consented to by the
Administrative Agent); and 
 (D) in connection with the establishment of any New Revolving Credit
Commitments that will include swingline loan and/or letter of credit subfacilities, any amendment to this Agreement pursuant to this Section 2.14(h)(ii) may include provisions relating to swingline loans and/or letters of credit, as applicable,
issued thereunder, which issuances shall be on terms similar (except for the overall size of such subfacilities and the identity of the swingline lender and letter of credit issuer, as applicable, and borrowing, repayment and termination of
commitment procedures, in each case which shall be  

  

#4812-2844-92899582-0297 
 -115- 

 
specified in the applicable Incremental Amendment) to the terms relating to Swingline Loans and Letters of Credit with respect to the Revolving Credit Commitments or otherwise reasonably
acceptable to the Administrative Agent and any applicable swingline lender or letter of credit issuer thereunder. 

2.15. Extensions of Term Loans and Revolving Credit Loans and Revolving Credit Commitments. (a)(i) The Borrower may at any time
and from time to time request that all or a portion of the Term Loans of any Class (an “Existing Term Loan Class”) be exchanged to extend the scheduled final maturity date(s) of any payment of principal with respect to
all or any portion of the principal amount of such Loans (any such Term Loans which have been so extended, “Extended Term Loans”) and to provide for other terms consistent with this Section 2.15. In order to
establish any Extended Term Loans, the Borrower shall provide a notice to the Administrative Agent (who shall provide a copy of such notice to each of the Lenders of the applicable Existing Term Loan Class) (a “Term Loan
Extension Request”) setting forth the proposed terms of the Extended Term Loans to be established, which terms shall be similar to the Term Loans of the Existing Term Loan Class from which they are to be extended except
that (w) the scheduled final maturity date shall be extended and all or any of the scheduled amortization payments of all or a portion of any principal amount of such Extended Term Loans may be delayed to later dates than the scheduled
amortization of principal of the Term Loans of such Existing Term Loan Class (with any such delay resulting in a corresponding adjustment to the scheduled amortization payments reflected in Section 2.5 or in the Incremental Amendment, as the
case may be, with respect to the Existing Term Loan Class of Term Loans from which such Extended Term Loans were extended, in each case as more particularly set forth in paragraph (c) of this Section 2.15 below), (x) (A) the
interest rates, interest margins, upfront fees, funding discounts, original issue discounts and premiums (including through fixed interest rates) with respect to the Extended Term Loans may be different than those for the Term Loans of such Existing
Term Loan Class and/or (B) additional fees may be payable to the Lenders providing such Extended Term Loans in addition to or in lieu of any of the items contemplated by the preceding clause (A), in each case, to the extent provided in the
applicable Extension Amendment, (y) subject to the provisions set forth in Sections 5.1 and 5.2, the Extended Term Loans may have optional prepayment terms (including call protection and prepayment premiums) and mandatory prepayment terms as
may be agreed between the Borrower and the Lender thereof and (z) the Extension Amendment may provide for other covenants and terms that apply solely to any period after the Latest Maturity Date, provided that the principal amount of the
Extended Term Loans shall not exceed the principal amount of the Term Loans being extended. No Lender shall have any obligation to agree to have any of its Term Loans of any Existing Term Loan Class exchanged into Extended Term Loans pursuant to any
Term Loan Extension Request. Any Extended Term Loans of any Extension Series shall constitute a separate Class of Term Loans from the Existing Term Loan Class of Term Loans from which they were extended. 

(ii) The Borrower may at any time and from time to time request that all or a portion of the Revolving Credit Commitments, any
previously extended Extended Revolving Credit Commitments and/or any New Revolving Credit Commitments, each existing at the time of such request (each, an “Existing Revolving Credit Commitment” and any related
revolving credit loans thereunder, “Existing Revolving Credit Loans”) be exchanged to extend the termination date thereof and the scheduled maturity date(s) of any payment of principal with respect to all or a portion
of any principal amount of Existing Revolving Credit Loans related to such Existing Revolving Credit Commitments (any such Existing Revolving Credit Commitments which have been so extended, “Extended Revolving Credit
Commitments” and any related Loans, “Extended Revolving Credit Loans”) and to provide for other terms consistent with this Section 2.15. In order to establish any Extended Revolving Credit
Commitments, the Borrower shall provide a notice to the Administrative Agent (who shall provide a copy of such notice to each of the Lenders of the applicable Class of Existing Revolving Credit Commitments) (a “Revolving Credit
Extension Request”) setting forth the proposed terms of the Extended Revolving Credit  

  

#4812-2844-92899582-0297 
 -116- 

 
Commitments to be established, which terms shall be similar to those applicable to the Existing Revolving Credit Commitments from which they are to be extended (the “Specified
Existing Revolving Credit Commitment”) except (w) all or any of the final maturity dates of such Extended Revolving Credit Commitments may be delayed to later dates than the final maturity dates of the Specified Existing
Revolving Credit Commitments, (x) (A) the interest rates, interest margins, rate floors, upfront fees, funding discounts, original issue discount and premiums with respect to the Extended Revolving Credit Commitments may be different than
those for the Specified Existing Revolving Credit Commitments and/or (B) additional fees may be payable to the Lenders providing such Extended Revolving Credit Commitments in addition to or in lieu of any of the items contemplated by the
preceding clause (A), (y) the undrawn revolving credit commitment fee rate with respect to the Extended Revolving Credit Commitments may be different than such rate for the Specified Existing Revolving Credit Commitment and (z) the
Extension Amendment may provide for other covenants and terms that apply solely to any period after the Latest Maturity Date; provided that the amount of the Extended Revolving Credit Commitments and the principal amount of the Extended Revolving
Credit Loans shall not exceed the amount of the Specified Existing Revolving Credit Commitments being extended and the principal amount of the related Existing Revolving Credit Loans being extended, respectively, and provided further that,
notwithstanding anything to the contrary in this Section 2.15 or otherwise, (1) the borrowing and repayment (other than in connection with a permanent repayment and termination of commitments) of the Extended Revolving Credit Loans under
any Extended Revolving Credit Commitments shall be made on a pro rata basis with any borrowings and repayments of the Specified Existing Revolving Credit Commitments (the mechanics for which may be implemented through the
applicable Extension Amendment and may include technical changes related to the borrowing and repayment procedures of the applicable Credit Facility), (2) assignments and participations of Extended Revolving Credit Commitments and Extended
Revolving Credit Loans shall be governed by the same assignment and participation provisions applicable to Revolving Credit Commitments and the Revolving Credit Loans related to such Commitments set forth in Section 13.6 and (3) subject to
Section 4.2, Section 5.2(a)(iv), Section 5.2(e)(ii) and Section 10.1(y)(ii), permanent repayments of Old Revolving Credit Loans (and permanent reductions in Old Revolving Credit Commitments) or permanent reduction of Old
Revolving Credit Commitments shall be permitted as may be agreed between the Borrower and such Lenders thereof. Any Extended Revolving Credit Commitments of any Extension Series shall constitute a separate Class of revolving credit commitments from
the Specified Existing Revolving Credit Commitments and from any other Existing Revolving Credit Commitments (together with any other Extended Revolving Credit Commitments so established on such date). 

(iii) The Borrower may at any time and from time to time request that all or a portion of the Deposit L/C Loans of any Class
(an “Existing Deposit L/C Loan Class”) be exchanged to extend the scheduled final maturity date(s) of any payment of principal with respect to all or any portion of the principal amount of such Loans (any such Deposit
L/C Loans which have been so extended, “Extended Deposit L/C Loans”) and to provide for other terms consistent with this Section 2.15. In order to establish any Extended Deposit L/C Loans, the Borrower shall
provide a notice to the Administrative Agent (who shall provide a copy of such notice to each of the Lenders of the applicable Existing Deposit L/C Loan Class) (a “Deposit L/C Loan Extension Request”) setting forth the
proposed terms of the Extended Deposit L/C Loans to be established, which terms shall be similar to the Deposit L/C Loans of the Existing Deposit L/C Loan Class from which they are to be extended except that (w) the scheduled final maturity
date shall be extended and all or any of the scheduled amortization payments of all or a portion of any principal amount of such Extended Deposit L/C Loans may be delayed to later dates than the scheduled amortization of principal of the Deposit L/C
Loans of such Existing Deposit L/C Loan Class (with any such delay resulting in a corresponding adjustment to the scheduled amortization payments reflected in Section 2.5 or in the Incremental Amendment, as the case may be, with respect to the
Existing Deposit L/C Loan Class of Deposit L/C Loans from which such Extended Deposit L/C Loans were extended, in each case as more particularly set forth in paragraph (c) of this Section 2.15 below), (x) (A) the interest rates,
interest 

  

#4812-2844-92899582-0297 
 -117- 

 
margins, upfront fees, funding discounts, original issue discounts and premiums (including through fixed interest rates) with respect to the Extended Deposit L/C Loans may be different from
those for the Deposit L/C Loans of such Existing Deposit L/C Loan Class and/or (B) additional fees may be payable to the Lenders providing such Extended Deposit L/C Loans in addition to or in lieu of any of the items contemplated by the
preceding clause (A), in each case, to the extent provided in the applicable Extension Amendment, (y) subject to the provisions set forth in Sections 5.1 and 5.2, the Extended Deposit L/C Loans may have optional prepayment terms (including call
protection and prepayment premiums) and mandatory prepayment terms as may be agreed between the Borrower and the Lender thereof and (z) the Extension Amendment may provide for other covenants and terms that apply solely to any period after the
Latest Maturity Date, provided that the principal amount of the Extended Deposit L/C Loans shall not exceed the principal amount of the Existing Deposit L/C Loans being extended. No Lender shall have any obligation to agree to have any of its
Deposit L/C Loans of any Existing Deposit L/C Loan Class exchanged into Extended Deposit L/C Loans pursuant to any Deposit L/C Loan Extension Request. Any Extended Deposit L/C Loans of any Extension Series shall constitute a separate Class of
Deposit L/C Loans from the Existing Deposit L/C Loan Class of Deposit L/C Loans from which they were extended. Notwithstanding anything to the contrary contained in this Section 2.15(a)(iii), the applicable Extension Amendment may provide that
the Deposit L/C Termination Date may be extended and the related obligations to make Deposit Letters of Credit may be continued so long as the applicable Deposit Letter of Credit Issuer has consented to such extensions (it being understood that no
consent of any other Lender shall be required in connection with any such extension).  
 (b) The Borrower shall
provide the applicable Extension Request at least five (5) Business Days (or such shorter period as the Administrative Agent may determine in its discretion) prior to the date on which Lenders under the Existing Class are requested to respond,
and shall agree to such procedures, if any, as may be established by, or acceptable to, the Administrative Agent in each case acting reasonably to accomplish the purposes of this Section 2.15 (it being understood that the offer and allocation
procedures for each Extension Series shall be substantially similar to those used for the offer and allocation of loans as provided in Amendment No. 2). Any Lender (an “Extending Lender”) wishing to have all or a
portion of its Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class subject to such Extension Request exchanged into Extended Loans/Commitments
shall notify the Administrative Agent (an “Extension Election”) on or prior to the date specified in such Extension Request of the amount of its Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New
Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class which it has elected to exchange into Extended Loans/Commitments (subject to any minimum denomination requirements imposed by the Administrative Agent). In
the event that the aggregate amount of Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class subject to Extension Elections exceeds the amount of
Extended Loans/Commitments requested pursuant to the Extension Request, Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments subject to Extension Elections shall be
converted to Extended Loans/Commitments as provided for in the applicable Extension Amendment. Notwithstanding the conversion of any Existing Revolving Credit Commitment (other than a New Revolving Credit Commitment) into an Extended Revolving
Credit Commitment, such Extended Revolving Credit Commitment shall be treated identically to all other Old Revolving Credit Commitments for purposes of the obligations of a Revolving Credit Lender in respect of Swingline Loans under
Section 2.1(e) and Revolving Letters of Credit under Article 3, except that the applicable Extension Amendment may provide that the Swingline Maturity Date and/or the Revolving L/C Maturity Date may be extended and the related obligations to
make Swingline Loans and issue Revolving Letters of Credit may be continued so long as the applicable Swingline Lender and/or the applicable Revolving Letter of Credit Issuer, as applicable, have consented to such extensions (it being

  

#4812-2844-92899582-0297 
 -118- 

 
understood that no consent of any other Lender shall be required in connection with any such extension). Notwithstanding the conversion of any Existing Revolving Credit Commitment that is a
New Revolving Credit Commitment (or any previously extended New Revolving Credit Commitment) into an Extended Revolving Credit Commitment, such Extended Revolving Credit Commitment shall be treated identically to all other Old Revolving Credit
Commitments for purposes of the obligations of a Lender in respect of swingline loans and letters of credit, except that the applicable Extension Amendment may provide that the swingline maturity date and/or the letter of credit maturity date may be
extended and the related obligations to make swingline loans and issue letters of credit may be continued so long as the applicable swingline lender and/or the applicable letter of credit issuer, as applicable, have consented to such extensions (it
being understood that no consent of any other Lender shall be required in connection with any such extension).  

(c) Extended Loans/Commitments shall be established pursuant to an amendment (an “Extension
Amendment”) to this Agreement (which, except to the extent expressly contemplated by the penultimate sentence of this Section 2.15(c) and notwithstanding anything to the contrary set forth in Section 13.1, shall not require
the consent of any Lender other than the Extending Lenders with respect to the Extended Loans/Commitments established thereby) executed by the Credit Parties, the Administrative Agent and the Extending Lenders. No Extension Amendment shall provide
for any tranche of Extended Loans/Commitments in an aggregate principal amount that is less than $50,000,000. In addition to any terms and changes required or permitted by Section 2.15(a), each Extension Amendment in respect of Extended Term
Loans shall amend the scheduled amortization payments pursuant to Section 2.5 or the applicable Incremental Amendment with respect to the Existing Class of Term Loans from which the Extended Term Loans were exchanged to reduce each scheduled
Repayment Amount for the Existing Class in the same proportion as the amount of Term Loans of the Existing Class is to be reduced pursuant to such Extension Amendment (it being understood that the amount of any Repayment Amount payable with respect
to any individual Term Loan of such Existing Class that is not an Extended Term Loan shall not be reduced as a result thereof). Notwithstanding anything to the contrary in this Section 2.15 and without limiting the generality or applicability
of Section 13.1 to any Section 2.15 Additional Amendments, any Extension Amendment may provide for additional terms and/or additional amendments other than those referred to or contemplated above (any such additional amendment, a
“Section 2.15 Additional Amendment”) to this Agreement and the other Credit Documents; provided that such Section 2.15 Additional Amendments do not become effective prior to the time that such Section 2.15
Additional Amendments have been consented to (including, without limitation, pursuant to (1) consents applicable to holders of Incremental Term Loans, Incremental Deposit L/C Loans, New Revolving Credit Commitments and Incremental Revolving
Commitment Increases provided for in any Incremental Amendment and (2) consents applicable to holders of any Extended Loans/Commitments provided for in any Extension Amendment) by such of the Lenders, Credit Parties and other parties (if any)
as may be required in order for such Section 2.15 Additional Amendments to become effective in accordance with Section 13.1. It is understood and agreed that each Lender that has consented to Amendment No. 2 has consented, and shall
at the effective time thereof be deemed to consent to each amendment to this Agreement and the other Credit Documents authorized by this Section 2.15 and the arrangements described above in connection therewith except that the foregoing shall
not constitute a consent on behalf of any Lender to the terms of any Section 2.15 Additional Amendment. In connection with any Extension Amendment, the Borrower shall deliver an opinion of counsel reasonably acceptable to the Administrative
Agent (i) as to the enforceability of such Extension Amendment, the Credit Agreement as amended thereby, and such of the other Credit Documents (if any) as may be amended thereby (in the case of such other Credit Documents as contemplated by
the immediately preceding sentence) and (ii) to the effect that such Extension Amendment, including without limitation, the Extended Loans/Commitments provided for therein, does not conflict with or violate the terms and provisions of
Section 13.1 of this Agreement.

 (d) Notwithstanding anything to the contrary contained in this Agreement,
(A) on any date on which any Existing Term Loan Class, Existing Deposit L/C Loan Class or Class of Existing Revolving Credit Commitments is exchanged to extend the related scheduled maturity date(s) in accordance with paragraph (a) above
(an “Extension Date”), (I) in the case of the existing Term Loans of each Extending Lender, the aggregate principal amount of such existing Term Loans shall be deemed reduced by an amount equal to the aggregate
principal amount of Extended Term Loans so exchanged by such Lender on such date, and the Extended Term Loans shall be established as a separate Class of Term Loans (together with any other Extended Term Loans so established on such date), (II) in
the case of the existing Deposit L/C Loans of each Extending Lender, the aggregate principal amount of such existing Deposit L/C Loans shall be deemed reduced by an amount equal to the aggregate principal amount of Extended Deposit L/C Loans so
exchanged by such Lender on such date, and the Extended Deposit L/C Loans shall be established as a separate Class of Deposit L/C Loans (together with any other Extended Deposit L/C Loans so established on such date), and (III) in the case of the
Specified Existing Revolving Credit Commitments of each Extending Lender, the aggregate principal amount of such Specified Existing Revolving Credit Commitments shall be deemed reduced by an amount equal to the aggregate principal amount of Extended
Revolving Credit Commitments so exchanged by such Lender on such date, and such Extended Revolving Credit Commitments shall be established as a separate Class of revolving credit commitments from the Specified Existing Revolving Credit Commitments
and from any other Existing Revolving Credit Commitments (together with any other Extended Revolving Credit Commitments so established on such date) and (B) if, on any Extension Date, any Loans of any Extending Lender are outstanding under the
applicable Specified Revolving Credit Commitments, such Loans (and any related participations) shall be deemed to be allocated as Extended Revolving Credit Loans (and related participations) and Existing Revolving Credit Loans (and related
participations) in the same proportion as such Extending Lender’s Specified Revolving Credit Commitments to Extended Revolving Credit Commitments. 
 (e) In the event that the Administrative Agent determines in its sole discretion that the allocation of Extended Term Loans of a given Extension Series, Extended Deposit L/C Loans of a given
Extension Series or the Extended Revolving Credit Commitments of a given Extension Series, in each case to a given Lender was incorrectly determined as a result of manifest administrative error in the receipt and processing of an Extension Election
timely submitted by such Lender in accordance with the procedures set forth in the applicable Extension Amendment, then the Administrative Agent, the Borrower and such affected Lender may (and hereby are authorized to), in their sole discretion and
without the consent of any other Lender, enter into an amendment to this Agreement and the other Credit Documents (each, a “Corrective Extension Amendment”) within 15 days following the effective date of such Extension
Amendment, as the case may be, which Corrective Extension Amendment shall (i) provide for the conversion and extension of Term Loans under the Existing Term Loan Facility, Deposit L/C Loans under the Existing Deposit L/C Loan Facility or
Existing Revolving Credit Commitments (and related Revolving Credit Exposure), as the case may be, in such amount as is required to cause such Lender to hold Extended Term Loans, Extended Deposit L/C Loans or Extended Revolving Credit Commitments
(and related Revolving Credit Exposure) of the applicable Extension Series into which such other Term Loans, Deposit L/C Loans or Revolving Credit Commitments or New Revolving Credit Commitments, as the case may be, were initially converted, as the
case may be, in the amount such Lender would have held had such administrative error not occurred and had such Lender received the minimum allocation of the applicable Loans or Commitments to which it was entitled under the terms of such Extension
Amendment, in the absence of such error, (ii) be subject to the satisfaction of such conditions as the Administrative Agent, the Borrower and such Lender may agree (including conditions of the type required to be satisfied for the effectiveness
of an Extension Amendment described in Section 2.15(c)), and (iii) effect such other amendments of the type (with appropriate reference and nomenclature changes) described in the penultimate sentence of Section 2.15(c). 

  

#4812-2844-92899582-0297 
 -120- 

 (f) No exchange of Loans or Commitments pursuant to any Extension Amendment in
accordance with this Section 2.15 shall constitute a voluntary or mandatory payment or prepayment for purposes of this Agreement. 
 2.16. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long
as such Lender is a Defaulting Lender: 
 (a) fees shall cease to accrue on the unfunded portion of the Commitment
of such Defaulting Lender pursuant to Section 4.1(a); 
 (b) if any Swingline Exposure or Revolving Letter of
Credit Exposure exists at the time a Lender becomes a Defaulting Lender, then (i) all or any part of such Revolving Letter of Credit Exposure of such Defaulting Lender and such Swingline Exposure of such Defaulting Lender will, subject to the
limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Revolving Credit Commitment Percentage;
provided that (A) each Non-Defaulting Lender’s Revolving Letter of Credit Exposure plus its Swingline Exposure may not in any event exceed the Revolving Credit Commitment of such Non-Defaulting Lender as in effect at the time of such
reallocation and (B) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Revolving Letter of Credit Issuers, the
Swingline Lender or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender, (ii) to the extent that all or any portion of the Defaulting Lender’s Revolving Letter of Credit
Exposure and Swingline Exposure cannot, or can only partially, be so reallocated to Non-Defaulting Lenders, whether by reason of the first proviso in Section 2.16(b)(i) above or otherwise, the Borrower shall within two Business Days following
notice by the Administrative Agent (x) first, prepay such Swingline Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) and (y) second, Cash Collateralize such Defaulting Lender’s Revolving
Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (i) above), in accordance with the procedures set forth in Section 3.8 for so long as such Revolving Letter of Credit Exposure is outstanding,
(iii) if the Borrower Cash Collateralizes any portion of such Defaulting Lender’s Revolving Letter of Credit Exposure pursuant to the requirements of this Section 2.16(b), the Borrower shall not be required to pay any fees to such
Defaulting Lender pursuant to Section 4.1(c) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Revolving Letter of Credit Exposure is Cash Collateralized, (iv) if the
Revolving Letter of Credit Exposure of the Non-Defaulting Lenders is reallocated pursuant to the requirements of this Section 2.16(b), then the fees payable to the Lenders pursuant to Section 4.1(c) shall be adjusted in accordance with
such Non-Defaulting Lenders’ Revolving Credit Commitment Percentages and the Borrower shall not be required to pay any fees to the Defaulting Lender pursuant to Section 4.1(c) with respect to such Defaulting Lender’s Revolving Letter
of Credit Exposure during the period that such Defaulting Lender’s Revolving Letter of Credit Exposure is reallocated, or (v) if any Defaulting Lender’s Revolving Letter of Credit Exposure is neither Cash Collateralized nor
reallocated pursuant to the requirements of this Section 2.16(b), then, without prejudice to any rights or remedies of the applicable Revolving Letter of Credit Issuer or any Lender hereunder, all fees payable under Section 4.1(c) with
respect to such Defaulting Lender’s Revolving Letter of Credit Exposure shall be payable to the applicable Revolving Letter of Credit Issuer until such Revolving Letter of Credit Exposure is Cash Collateralized and/or reallocated;

 (c) no Revolving Letter of Credit Issuer will be required to issue any new Revolving Letter of Credit or to amend
any outstanding Revolving Letter

of Credit to increase the face amount thereof, alter the drawing terms thereunder or extend the expiry date thereof, unless the applicable Revolving Letter of Credit Issuer is reasonably
satisfied that any exposure that would result from the exposure to such Defaulting Lender is eliminated or fully covered by the Revolving Credit Commitments of the Non-Defaulting Lenders or by Cash Collateralization or a combination thereof in
accordance with the requirements of Section 2.16(b) above or otherwise in a manner reasonably satisfactory to the applicable Revolving Letter of Credit Issuer;  
 (d) the Swingline Lender will not be required to fund any Swingline Loans unless the Swingline Lender is reasonably satisfied that any exposure that would result from the exposure to such
Defaulting Lender is eliminated or fully covered by the Revolving Credit Commitments of the Non-Defaulting Lenders or a combination thereof in accordance with the requirements of Section 2.16(b) above; and 

(e) If the Borrower, the Administrative Agent and the Revolving Letter of Credit Issuers agree in writing in their discretion
that a Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon, as of the effective date specified in such notice and subject to any conditions
set forth therein, such Lender will cease to be a Defaulting Lender and will be a Non-Defaulting Lender and any applicable Cash Collateral shall be promptly returned to the Borrower and any Revolving Letter of Credit Exposure of such Lender
reallocated pursuant to the requirements of Section 2.16(b) shall be reallocated back to such Lender; provided that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to
Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender. 
 2.17. Permitted Debt Exchanges. 
 (a) Notwithstanding
anything to the contrary contained in this Agreement, pursuant to one or more offers (each, a “Permitted Debt Exchange Offer”) made from time to time by the Borrower to all Lenders (other than any Lender that, if
requested by the Borrower, is unable to certify that it is either a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (as defined in Rule 501 under the
Securities Act)) with outstanding Term Loans under one or more Classes of Term Loans (as determined by the Borrower in its sole discretion) on the same terms, the Borrower may from time to time consummate one or more exchanges of Term Loans for
Permitted Other Notes (such notes, “Permitted Debt Exchange Notes” and each such exchange, a “Permitted Debt Exchange”), so long as the following conditions are satisfied: (i) no
Default or Event of Default shall have occurred and be continuing at the time the offering document in respect of a Permitted Debt Exchange Offer is delivered to the relevant Lenders, (ii) the aggregate principal amount (calculated on the face
amount thereof) of Term Loans exchanged shall equal the aggregate principal amount (calculated on the face amount thereof) of Permitted Debt Exchange Notes issued in exchange for such Term Loans, (iii) the aggregate principal amount (calculated
on the face amount thereof) of all Term Loans exchanged under each applicable Class by the Borrower pursuant to any Permitted Debt Exchange shall automatically be cancelled and retired by the Borrower on date of the settlement thereof (and, if
requested by the Administrative Agent, any applicable exchanging Lender shall execute and deliver to the Administrative Agent an Assignment and Acceptance, or such other form as may be reasonably requested by the Administrative Agent, in respect
thereof pursuant to which the respective Lender assigns its interest in the Term Loans being exchanged pursuant to the Permitted Debt Exchange to the Borrower for immediate cancellation), (iv) if the aggregate principal amount of all Term Loans
(calculated on the face amount thereof) of a given Class tendered by Lenders in respect of the relevant Permitted Debt Exchange Offer (with no Lender being permitted to tender a principal amount of Term Loans which exceeds the principal amount
thereof of the applicable Class actually held by it) shall exceed the maximum aggregate principal amount of Term Loans of such Class offered to be exchanged by the Borrower pursuant to such Permitted 

  

#4812-2844-92899582-0297 
 -122- 

 
Debt Exchange Offer, then the Borrower shall exchange Term Loans under the relevant Class tendered by such Lenders ratably up to such maximum based on the respective principal amounts so
tendered, or if such Permitted Debt Exchange Offer shall have been made with respect to multiple Classes without specifying a maximum aggregate principal amount offered to be exchanged for each Class, and the aggregate principal amount of all Term
Loans (calculated on the face amount thereof) of all Classes tendered by Lenders in respect of the relevant Permitted Debt Exchange Offer (with no Lender being permitted to tender a principal amount of Term Loans which exceeds the principal amount
thereof actually held by it) shall exceed the maximum aggregate principal amount of Term Loans of all relevant Classes offered to be exchanged by the Borrower pursuant to such Permitted Debt Exchange Offer, then the Borrower shall exchange Term
Loans across all Classes subject to such Permitted Debt Exchange Offer tendered by such Lenders ratably up to such maximum amount based on the respective principal amounts so tendered, (v) each such Permitted Exchange Offer shall be made on a
pro rata basis to the Lenders (other than any Lender that, if requested by the Borrower, is unable to certify that it is either a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional
“accredited investor” (as defined in Rule 501 under the Securities Act)) of each applicable Class based on their respective aggregate principal amounts of outstanding Term Loans under each such Class, (vi) all documentation in respect
of such Permitted Debt Exchange shall be consistent with the foregoing, and all written communications generally directed to the Lenders in connection therewith shall be in form and substance consistent with the foregoing and made in consultation
with the Borrower and the Administrative Agent, and (vii) any applicable Minimum Tender Condition or Maximum Tender Condition, as the case may be, shall be satisfied or waived by the Borrower.  

(b) With respect to all Permitted Debt Exchanges effected by the Borrower pursuant to this Section 2.17, (i) such
Permitted Debt Exchanges (and the cancellation of the exchanged Term Loans in connection therewith) shall not constitute voluntary or mandatory payments or prepayments for purposes of Section 5.1 or 5.2, and (ii) such Permitted Debt
Exchange Offer shall be made for not less than $50,000,000 in aggregate principal amount of Term Loans, provided that subject to the foregoing clause (ii) the Borrower may at its election specify (A) as a condition (a
“Minimum Tender Condition”) to consummating any such Permitted Debt Exchange that a minimum amount (to be determined and specified in the relevant Permitted Debt Exchange Offer in the Borrower’s discretion) of
Term Loans of any or all applicable Classes be tendered and/or (B) as a condition (a “Maximum Tender Condition”) to consummating any such Permitted Debt Exchange that no more than a maximum amount (to be
determined and specified in the relevant Permitted Debt Exchange Offer in the Borrower’s discretion) of Term Loans of any or all applicable Classes will be accepted for exchange.  

(c) In connection with each Permitted Debt Exchange, the Borrower shall provide the Administrative Agent at least five
(5) Business Days’ (or such shorter period as may be agreed by the Administrative Agent) prior written notice thereof, and the Borrower and the Administrative Agent, acting reasonably, shall mutually agree to such procedures as may be
necessary or advisable to accomplish the purposes of this Section 2.17 and without conflict with Section 2.17(d); provided that the terms of any Permitted Debt Exchange Offer shall provide that the date by which the relevant Lenders are
required to indicate their election to participate in such Permitted Debt Exchange shall be not less than five (5) Business Days following the date on which the Permitted Debt Exchange Offer is made. 

(d) The Borrower shall be responsible for compliance with, and hereby agrees to comply with, all applicable securities and
other laws in connection with each Permitted Debt Exchange, it being understood and agreed that (x) neither the Administrative Agent nor any Lender assumes any responsibility in connection with the Borrower’s compliance with such laws in
connection with any Permitted Debt Exchange and (y) each Lender shall be solely responsible for its compliance with any applicable “insider trading” laws and regulations to which such Lender may be subject under the Securities
Exchange Act of 1934, as amended.

benefit of the Borrower and the Restricted Subsidiaries and for the direct or indirect benefit of the Parent and its other Subsidiaries (excluding the Oncor Subsidiaries) so long as the aggregate Stated Amount of all Letters of Credit issued for the
Parent and its other Subsidiaries’ benefit does not exceed $250,000,000, a letter of credit or letters of credit (the “Revolving Letters of Credit” and each, a “Revolving Letter of Credit”) in such form and
with such Issuer Documents as may be approved by the Revolving Letter of Credit Issuer in its reasonable discretion; provided that the Borrower shall be a co-applicant, and jointly and severally liable with respect to each Revolving Letter of
Credit issued for the account of the Parent and its other Subsidiaries, US Holdings or a Restricted Subsidiary. 
 (ii)
Notwithstanding the foregoing, (A) no Revolving Letter of Credit shall be issued the Stated Amount of which, when added to the Revolving Letters of Credit Outstanding at such time, would exceed the Revolving Letter of Credit Commitment then in
effect; (B) no Revolving Letter of Credit shall be issued the Stated Amount of which would cause the aggregate amount of the Revolving Credit Exposures at such time to exceed the Total Revolving Credit Commitment then in effect; (C) each
Revolving Letter of Credit shall have an expiration date occurring no later than the earlier of (x) one year after the date of issuance thereof, unless otherwise agreed upon by the Administrative Agent and the Revolving Letter of Credit Issuer,
or as provided under Section 3.2(b) and (y) the Revolving L/C Maturity Date; provided that, to the extent that the 2011 Revolving Credit Commitment Extension Effective Date has occurred, no Revolving Letter of Credit, other than
an Optional Revolving Letter of Credit, may have an expiration date occurring later than the Original Revolving L/C Maturity Date if on such date of issuance, the aggregate Stated Amount of all Revolving Letters of Credit having expiration dates

be denominated in Dollars; (E) no Revolving Letter of Credit shall be issued if it would be illegal under any Applicable Law for the beneficiary of the Revolving Letter of Credit to have a Revolving Letter of Credit issued in its favor;

such Default or Event of Default in accordance with the provisions of Section 13.1 or (z) that such Default or Event of Default is no longer continuing; and (G) other than in the case of Existing Letters of Credit, no Revolving

 -124- 

 
of all Revolving Letters of Credit having expiration dates after the Original Revolving L/C Maturity Date (including such Optional Revolving Letter of Credit and any other Optional Letters of
Credit), when added to the aggregate Revolving Credit Exposure of all 2016 Revolving Credit Lenders (exclusive of Revolving Letter of Credit Exposure with respect to such Revolving Letters of Credit) as of such date, may exceed the Total 2016
Revolving Credit Commitment then in effect. Any such Revolving Letter of Credit Issuer may require, as a condition to issuing any such an Optional Revolving Letter of Credit in its sole and absolute discretion, that the Borrower Cash Collateralize
the Revolving L/C Obligations with respect to such Optional Revolving Letters of Credit to the extent of the excess referred to in the preceding sentence (at such times as such Revolving Letter of Credit Issuer may required), or make other
arrangements satisfactory to such Revolving Letter of Credit Issuer, to eliminate or cover the exposure of such Revolving Letter of Credit Issuer with respect to such excess. Notwithstanding anything contained in this Agreement to the contrary, at
no time prior to the Original Revolving L/C Maturity Date shall the aggregate Stated Amount of all Revolving Letters of Credit having expiration dates after the Original Revolving L/C Maturity Date (excluding any Optional Revolving Letters of
Credit), when added to the aggregate Revolving Credit Exposure of all 2016 Revolving Credit Lenders (exclusive of Revolving Letter of Credit Exposure with respect to such Revolving Letters of Credit) as of such date, exceed the Total 2016 Revolving
Credit Commitment then in effect. 
 (b) Deposit Letters of Credit. (i) Subject to and upon the terms and
conditions herein set forth, at any time and from time to time on and after the Closing Date and prior to the Deposit L/C MaturityTermination Date, the Deposit Letter of Credit Issuer agrees to issue upon the request of and
for the account of the Borrower and the Restricted Subsidiaries and for the direct or indirect benefit of the Parent and its other Subsidiaries (excluding the Oncor Subsidiaries) so long as the aggregate Stated Amount of all Letters of Credit issued
for the Parent and its other Subsidiaries’ (excluding the Oncor Subsidiaries) benefit does not exceed $250,000,000, a letter of credit or letters of credit (the “Deposit Letters of Credit” and each a “Deposit Letter of
Credit”) in such form and with such Issuer Documents as may be approved by the Deposit Letter of Credit Issuer in its reasonable discretion; provided that the Borrower shall be a co-applicant, and be jointly and severally liable,
with respect to each Deposit Letter of Credit issued for the account of the Parent and its other Subsidiaries, US Holdings or a Restricted Subsidiary.

exceed the Deposit L/C Loan Collateral Account Balance, (B) no Citibank Deposit Letter of Credit shall be issued, the Stated Amount of which, when added to the Deposit Letters of Credit Outstanding in respect of all other Citibank Deposit
Letters of Credit at such time, would exceed the aggregate amount on deposit in the Citibank Deposit L/C Loan Collateral Account, (C) each Deposit Letter of Credit shall have an expiration date occurring no later than the earlier of
(x) one year after the date of issuance thereof, unless otherwise agreed upon by the Administrative Agent and the Deposit Letter of Credit Issuer or as provided under Section 3.2(b) and (y) the Deposit L/C

 -125- 

 3.2. Letter of Credit Requests. 

(a) (a) Whenever the Borrower desires that a Letter of Credit be issued, the Borrower shall give the
Administrative Agent and the applicable Letter of Credit Issuer a Letter of Credit Request by no later than 1:00 p.m. (New York City time) at least two (or such lesser number as may be agreed upon by the Administrative Agent and such Letter of
Credit Issuer) Business Days prior to the proposed date of issuance. Each notice shall be executed by the Borrower, shall specify whether such Letter of Credit is to be a Revolving Letter of Credit or Deposit Letter of Credit and shall be in the
form of Exhibit G, or such other form (including by electronic or fax transmission) as agreed between the Borrower, the Administrative Agent and the applicable Letter of Credit Issuer (each a “Letter of Credit Request”).

 (b) (b) If the Borrower so requests in any applicable Letter of Credit Request, any Letter of
Credit Issuer may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of
Credit must permit the Letter of Credit Issuer to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a
day (the “Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by a Letter of Credit Issuer, the Borrower shall not be required to make
a specific request to such Letter of Credit Issuer for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Borrower and, in the case of Revolving Letters of Credit, the Revolving Credit Lenders shall be deemed to have
authorized (but may not require) such Letter of Credit Issuer to permit the extension of such Letter of Credit at any time to an expiry date not later than, in the case of any Revolving Letter of Credit, the Revolving L/C Maturity Date subject to
the limitation set forth in the proviso of Section 3.1(a)(ii)(C), and in the case of any Deposit Letter of Credit, the Deposit L/C MaturityTermination Date; provided, however, that such Letter of Credit
Issuer shall not permit any such extension if (A) such Letter of Credit Issuer has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the
terms hereof (by reason of the provisions of clause (ii) of either Sections 3.1(a) or (b), as applicable, or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that
is five Business Days before the Non-Extension Notice Date from the Administrative Agent or the Borrower that one or more of the applicable conditions specified in Section 7 are not then satisfied, and in each such case directing such
Letter of Credit Issuer not to permit such extension. 
 (c) (c) Each Letter of Credit Issuer
shall, at least once each week, provide the Administrative Agent a list of all Letters of Credit (including any Existing Letter of Credit) issued by it that are outstanding at such time and specifying whether such Letters of Credit are Revolving
Letters of Credit or Deposit Letters of Credit; provided that upon written request from the Administrative Agent, such Letter of Credit Issuer shall thereafter notify the Administrative Agent in writing on each Business Day of all Letters of
Credit issued on the prior Business Day by such Letter of Credit Issuer and specifying whether such Letters of Credit are Revolving Letters of Credit or Deposit Letters of Credit. 

(d) (d) The making of each Letter of Credit Request shall be deemed to be a representation and warranty by
the Borrower that the Letter of Credit may be issued in accordance with, and will not violate the requirements of, Section 3.1(a)(ii) or Section 3.1(b)(ii), as applicable. 

3.3. Revolving Letter of Credit Participations. 
 (a) Immediately upon the issuance by the Revolving Letter of Credit Issuer of any Revolving Letter of Credit (and on the Closing Date in respect of Existing Letters of Credit denoted as “Revolving
Letters of Credit” on Schedule 1.1(b)), the Revolving Letter of Credit Issuer shall be deemed to have sold and transferred to each Revolving Credit Lender (each such Revolving Credit Lender, in its

  

#4812-2844-92899582-0297 
 -126- 

 
capacity under this Section 3.3, a “Revolving L/C Participant”), and each such Revolving L/C Participant shall be deemed irrevocably and unconditionally to have
purchased and received from the Revolving Letter of Credit Issuer, without recourse or warranty, an undivided interest and participation (each a “Revolving L/C
Participation”), to the extent of such Revolving L/C Participant’s Revolving Credit Commitment Percentage, in each Revolving Letter of Credit, each substitute therefor, each
drawing made thereunder and the obligations of the Borrower under this Agreement with respect thereto (each, a “Revolving L/C Participation”) pro rata based on such Revolving L/C
Participant’s Revolving Credit Commitment Percentage (determined without regard to the Class of Revolving Credit Commitments held by such Lender), and any security therefor or guaranty pertaining thereto. 

(b) In determining whether to pay under any Revolving Letter of Credit, the Revolving Letter of Credit Issuer shall have no obligation
relative to the Revolving L/C Participants other than to confirm that (i) any documents required to be delivered under such Revolving Letter of Credit have been delivered, (ii) the Revolving Letter of Credit Issuer has examined the
documents with reasonable care and (iii) the documents appear to comply on their face with the requirements of such Revolving Letter of Credit. Any action taken or omitted to be taken by the Revolving Letter of Credit Issuer under or in
connection with any Revolving Letter of Credit issued by it, if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for the Revolving Letter of Credit Issuer any resulting liability. 

(c) Whenever the Revolving Letter of Credit Issuer receives a payment in respect of an unpaid reimbursement obligation as to which the
Administrative Agent has received for the account of the Revolving Letter of Credit Issuer any payments from the Revolving L/C Participants, the Revolving Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent
shall promptly pay to each Revolving L/C Participant that has paid its Revolving Credit Commitment Percentage (determined without regard to the Class of Revolving Credit Commitments held by such Lender) of such reimbursement obligation, in
Dollars and in immediately available funds, an amount equal to such Revolving L/C Participant’s share (based upon the proportionate aggregate amount originally funded by such Revolving L/C Participant to the aggregate amount funded by all
Revolving L/C Participants) of the principal amount so paid in respect of such reimbursement obligation and interest thereon accruing after the purchase of the respective Revolving L/C Participations at the Overnight Rate. For the avoidance of
doubt, all distributions under this Section 3.3(c) shall be made to each Lender with a Revolving Credit Commitment pro rata based on each such Lender’s Revolving Credit Commitment Percentage without regard to the Class of Revolving Credit
Commitments held by such Lender.  
 (d) The obligations of the Revolving L/C Participants to make payments to the
Administrative Agent for the account of the Revolving Letter of Credit Issuer with respect to Revolving Letters of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including under any of the following circumstances: 

(i) any lack of validity or enforceability of this Agreement or any of the other Credit Documents; 

(ii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against a
beneficiary named in a Revolving Letter of Credit, any transferee of any Revolving Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, the Revolving Letter of Credit Issuer, any Lender or other
Person, whether in connection with this Agreement, any Revolving Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower and the beneficiary named in any such
Revolving Letter of Credit); 

  

#4812-2844-92899582-0297 
 -127- 

 (iii) any draft, certificate or any other document presented under any
Revolving Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 

(iv) the surrender or impairment of any security for the performance or observance of any of the terms of any of the
Credit Documents; or 
 (v) the occurrence of any Default or Event of Default; 

provided, however, that no Revolving L/C Participant shall be obligated to pay to the Administrative Agent for the account of the Revolving
Letter of Credit Issuer its Revolving Credit Commitment Percentage of any unreimbursed amount arising from any wrongful payment made by the Revolving Letter of Credit Issuer under a Revolving Letter of Credit as a result of acts or omissions
constituting willful misconduct or gross negligence on the part of the Revolving Letter of Credit Issuer. 
 (e) On
the 2011 Revolving Credit Commitment Extension Effective Date, the Revolving L/C Participations in any issued and outstanding Revolving Letters of Credit shall be reallocated so that after giving effect thereto the 2016 Revolving Credit Lenders and
the 2013 Revolving Credit Lenders shall share ratably in such Revolving L/C Participations in accordance with the aggregate Revolving Credit Commitments (including both the 2013 Revolving Credit Commitments and the 2016 Revolving Credit Commitments
from time to time in effect). Thereafter, until the Original Revolving L/C Maturity Date, Revolving L/C Participations in any newly-issued Revolving Letters of Credit shall be allocated in accordance with the aggregate Revolving Credit Commitments
(including both the 2013 Revolving Credit Commitments and the 2016 Revolving Credit Commitments from time to time in effect). Notwithstanding anything contained in this Agreement to the contrary, to the extent that the 2011 Revolving Credit
Commitment Extension Effective Date has occurred, on the Original Revolving L/C Maturity Date, the interests and participations of the 2013 Revolving Lenders in the Revolving Letters of Credit (if any) outstanding as at such day shall automatically
terminate at the close of business on such date and (i) from and after the Original Revolving L/C Maturity Date, the 2013 Revolving Credit Lenders shall have no liability arising from, relating to, in connection with or otherwise in respect of,
such interests and participations or Revolving Letter of Credit, and (ii) such interests and participations in outstanding Revolving Letters of Credit shall thereupon automatically and without further action be re-allocated to the extent
necessary such that the interests and participations in such Revolving Credit Letters of Credit shall be held by the 2016 Revolving Credit Lenders ratably in proportion to their respective 2016 Revolving Credit Commitments. 

3.4. Agreement to Repay Letter of Credit Drawings. 
 (a) The Borrower hereby agrees to reimburse the applicable Letter of Credit Issuer, by making payment in Dollars to the Administrative Agent in immediately available funds, for any payment or disbursement
made by such Letter of Credit Issuer under any Letter of Credit (each such amount so paid until reimbursed, an “Unpaid Drawing”) (i) within two Business Days of the date of such payment or disbursement, if such Letter of Credit
Issuer provides notice to the Borrower of such payment or disbursement prior to 10:00 a.m. (New York City time) on such next succeeding Business Day from the date of such payment or disbursement or (ii) if such notice is received after such
time, on the second Business Day following the date of receipt of such notice (such required date for reimbursement under clause (i) or (ii), as applicable, the “Reimbursement Date”), with interest on the amount so paid or

  

#4812-2844-92899582-0297 
 -128- 

 
disbursed by such Letter of Credit Issuer, from and including the date of such payment or disbursement to but excluding the Reimbursement Date, at the per annum rate for each day equal to the
Overnight Rate; provided that, notwithstanding anything contained in this Agreement to the contrary, (i) in the case of any Unpaid Drawings under any Revolving Letters of Credit, (A) unless the Borrower shall have notified the
Administrative Agent and the relevant Letter of Credit Issuer prior to 10:00 a.m. (New York City time) on the Reimbursement Date that the Borrower intends to reimburse the relevant Letter of Credit Issuer for the amount of such drawing with funds
other than the proceeds of Revolving Credit Loans, the Borrower shall be deemed to have given a Notice of Borrowing requesting that, with respect to Revolving Letters of Credit, the Lenders with Revolving Credit Commitments make Revolving
Credit Loans (which shall be ABR Loans) on the Reimbursement Date in the amount of such Unpaid Drawing and (B) the Administrative Agent shall promptly notify each Revolving Credit Lender of such drawing and the amount of its Revolving Credit
Loan to be made in respect thereof (without regard to the Minimum Borrowing Amount), and each Revolving L/C Participant shall be irrevocably obligated to make a Revolving Credit Loan to the Borrower in the manner deemed to have been requested in the
amount of its Revolving Credit Commitment Percentage (determined without regard to the Class of Revolving Credit Commitments held by such Lender) of the applicable Unpaid Drawing by 2:00 p.m. (New York City time) on such Reimbursement Date by
making the amount of such Revolving Credit Loan available to the Administrative Agent and the Administrative Agent shall use the proceeds of such Revolving Credit Loans solely for purpose of reimbursing the relevant Letter of Credit Issuer for the
related Unpaid Drawing or (ii), in the case of any Unpaid Drawing under any Deposit Letter of Credit, unless the Borrower shall have notified the Administrative Agent and the relevant Letter of Credit Issuer prior to 10:00 a.m. (New York City time)
on the Reimbursement Date that the Borrower intends to reimburse the relevant Letter of Credit Issuer for the amount of such drawing with its own funds, the Collateral Agent shall promptly cause the amounts on deposit in the Deposit L/C Loan
Collateral AccountAccounts to be applied to repay in full the amount of such Unpaid Drawing., provided that after giving effect to such application the Deposit Letters of Credit Outstanding with respect to
Citibank Deposit Letters of Credit at such time would not exceed the aggregate amount on deposit in the Citibank Deposit L/C Loan Collateral Account. For the avoidance of doubt, all Borrowings of Revolving Credit Loans under this
Section 3.4(a) shall be made by each Lender with a Revolving Credit Commitment pro rata based on each such Lender’s Revolving Credit Commitment Percentage (determined without regard to Class of Revolving Credit Commitments held by such
Lender).  
 In the event that the Borrower fails to Cash Collateralize any Revolving Letter of Credit that is outstanding

replaced or resigning Revolving Letter of Credit Issuer, to issue “back-stop” Revolving Letters of Credit naming the resigning or replaced Revolving Letter of Credit Issuer as beneficiary for each outstanding Revolving Letter of Credit
issued by the resigning or replaced Revolving Letter of Credit Issuer, which new Revolving Letters of Credit shall have a face amount equal to the Revolving Letters of Credit being back-stopped and the sole requirement for drawing on such new
Revolving Letters of Credit shall be a drawing on the corresponding back-stopped Revolving Letters of Credit. After any resigning or replaced Letter of Credit Issuer’s resignation or replacement as Letter of Credit Issuer, the provisions of

replacement as set forth in clause (a) above, any outstanding Letters of Credit, nothing herein shall be deemed to impact or impair any rights and obligations of any of the parties hereto with respect to such outstanding Letters of
Credit (including, without limitation, any obligations related to the payment of Fees or the reimbursement or funding of amounts drawn), except that the Borrower, the resigning or replaced Letter of Credit Issuer and the successor issuer of Letters
of Credit shall have the obligations regarding outstanding Letters of Credit described in clause (a) above.

Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by such Letter of Credit Issuer’s willful misconduct or gross
negligence or such Letter of Credit Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of
Credit. In furtherance and not in limitation of the foregoing, each Letter of Credit Issuer 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, and no Letter of Credit Issuer shall be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds

the Term Loans to be rejected, any such failure will be deemed an acceptance of the total amount of such prepayment of Term Loans. Any Declined Proceeds remaining thereafter shall be retained by the Borrower (“Retained Declined
Proceeds”). 
 (i) Foreign Net Cash Proceeds and Excess Cash Flow. Notwithstanding any other provisions of this
Section 5.2, (i) to the extent that any or all of the Net Cash Proceeds from a Recovery Prepayment Event (a “Foreign Recovery Event”) of, or any Disposition by, a Restricted Foreign Subsidiary giving rise to an
Asset Sale Prepayment Event (a “Foreign Asset Sale”) or any amount included in Excess Cash Flow and attributable to Foreign Subsidiaries are prohibited or delayed by applicable local law from being repatriated to the United States,
such portion of the Net Cash Proceeds or Excess Cash Flow so affected will not be required to be applied to repay Term Loans at the times provided in this Section 5.2 but may be retained by the applicable Restricted Foreign Subsidiary so
long, but only so long, as the applicable local law will not permit repatriation to the United States (the Borrower hereby agreeing to cause the applicable Restricted Foreign Subsidiary to promptly take all actions required by the applicable local
law to permit such repatriation), and once such repatriation of any of such affected Net Cash Proceeds or Excess Cash Flow is permitted under the applicable local law, such repatriation will be immediately effected and such repatriated Net Cash
Proceeds will be promptly (and in any event not later than two Business Days after such repatriation) applied (net of additional taxes payable or reserved against as a result thereof) to the repayment of the Term Loans as required pursuant to this
Section 5.2 and (ii) to the extent that the Borrower has determined in good faith that repatriation of any of or all the Net Cash Proceeds of any Foreign Recovery Event, any Foreign Asset Sale or Excess Cash Flow would have a
material adverse tax consequence with respect to such Net Cash Proceeds or Excess Cash Flow, the Net Cash Proceeds or Excess Cash Flow so affected may be retained by the applicable Restricted Foreign Subsidiary; provided that, in the case of
this clause (ii), on or before the date on which any Net Cash Proceeds or Excess Cash Flow so retained would otherwise have been required to be applied to reinvestments or prepayments pursuant to Section 5.2(a), (x) the
Borrower applies an amount equal to such Net Cash Proceeds or Excess Cash Flow to such reinvestments or prepayments as if such Net Cash Proceeds or Excess Cash Flow had been received by the Borrower rather than such Restricted Foreign Subsidiary,
less the amount of additional taxes that would have been payable or reserved against if such Net Cash Proceeds or Excess Cash Flow had been repatriated (or, if less, the Net Cash Proceeds or Excess Cash Flow that would be calculated if received by
such Foreign Subsidiary) or (y) such Net Cash Proceeds or Excess Cash Flow are applied to the repayment of Indebtedness of a Restricted Foreign Subsidiary. 
 5.3. Method and Place of Payment. 
 (a) Except as otherwise specifically
provided herein, all payments under this Agreement shall be made by the Borrower without set-off, counterclaim or deduction of any kind, to the Administrative Agent for the ratable account of the Lenders entitled thereto, the Letter of Credit Issuer
or the Swingline Lender entitled thereto, as the case may be, not later than 2:00 p.m. (New York City time), in each case, on the date when due and shall be made in immediately available funds at the Administrative Agent’s Office or at such
other office as the Administrative Agent shall specify for such purpose by notice to the Borrower, it being understood that written or facsimile notice by the Borrower to the Administrative Agent to make a payment from the funds in the
Borrower’s account at the Administrative Agent’s Office shall constitute the making of such payment to the extent of such funds held in such account. All repayments or prepayments of any Loans (whether of principal, interest or otherwise)
hereunder and all other payments under each Credit Document shall be made in Dollars. The Administrative Agent will thereafter cause to be distributed on the same day (if payment was actually received by the Administrative Agent prior to 2:00 p.m.
(New York City time) or, otherwise, on the next Business Day) like funds relating to the payment of principal or interest or fees ratably to the Lenders entitled thereto.

 -145- 

 (b) Any payments under this Agreement that are made later than 2:00 p.m. (New York City
time) shall be deemed to have been made on the next succeeding Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the due date thereof shall be extended to the next succeeding
Business Day and, with respect to payments of principal, interest shall be payable during such extension at the applicable rate in effect immediately prior to such extension. 
 5.4. Net Payments. 
 (a) Any and all payments made by or on behalf of the
Borrower or any Guarantor under this Agreement or any other Credit Document shall be made free and clear of, and without deduction or withholding for or on account of, any Indemnified Taxes; provided that if the Borrower or any
Guarantor or the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) shall be required by Applicable Law to deduct or withhold any Indemnified Taxes from such payments, then (i) the sum payable by the Borrower or
any Guarantor shall be increased as necessary so that after making all required deductions and withholdings (including deductions or withholdings applicable to additional sums payable under this Section 5.4) the Administrative Agent, the
Collateral Agent, the Posting Agent or any Lender (which term shall include each Letter of Credit Issuer and the Swingline Lender for purposes of Section 5.4 and for the purposes of the definition of Excluded Taxes), as the case may be,
receives an amount equal to the sum it would have received had no such deductions or withholdings been made, (ii) the Borrower or such Guarantor or the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) shall make
such deductions or withholdings and (iii) the Borrower or such Guarantor or the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) shall timely pay the full amount deducted or withheld to the relevant Governmental
Authority within the time allowed and in accordance with Applicable Law. Whenever any Indemnified Taxes are payable by the Borrower or such Guarantor, as promptly as possible thereafter, the Borrower or Guarantor shall send to the Administrative
Agent (or, in the case of the Posting Facility, the Posting Agent) for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt (or other evidence acceptable to such Lender, acting
reasonably) received by the Borrower or such Guarantor showing payment thereof. 
 (b) The Borrower shall timely pay and shall
indemnify and hold harmless the Administrative Agent, the Posting Agent, the Collateral Agent and each Lender with regard to any Other Taxes (whether or not such Other Taxes were correctly or legally imposed or asserted by the relevant Governmental
Authority). 
 (c) The Borrower shall indemnify and hold harmless the Administrative Agent, the Posting Agent, the Collateral
Agent and each Lender within fifteen Business Days after written demand therefor, for the full amount of any Indemnified Taxes imposed on the Administrative Agent, the Posting Agent, the Collateral Agent or such Lender as the case may be, on or with
respect to any payment by or on account of any obligation of the Borrower or any Guarantor hereunder or under any other Credit Document (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this
Section 5.4) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate setting forth
reasonable detail as to the amount of such payment or liability delivered to the Borrower by a Lender, the Administrative Agent, the Posting Agent or the Collateral Agent (as applicable) on its own behalf or on behalf of a Lender shall be conclusive
absent manifest error.

 (d) Any Non-U.S. Lender that is entitled to an exemption from or reduction of withholding
tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or under any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Credit Document shall, to the extent it is
legally able to do so, deliver to the Borrower (with a copy to the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent)), at the time or times prescribed by Applicable Law or reasonably requested by the Borrower or the
Administrative Agent (or, in the case of the Posting Facility, the Posting Agent), such properly completed and executed documentation prescribed by Applicable Law as will permit such payments to be made without withholding or at a reduced rate of
withholding. A Lender’s obligation under the prior sentence shall apply only if the Borrower or the Administrative Agent has made a request for such documentation. In addition, any Lender, if requested by the Borrower or the Administrative
Agent (or, in the case of the Posting Facility, the Posting Agent), shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent (or, in the case of the Posting Facility, the
Posting Agent) as will enable the Borrower or the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

 (e) Each Non-U.S. Lender with respect to any Loan or Posting Advance made to the Borrower shall, to the extent it is legally
entitled to do so: 
 (i) deliver to the Borrower and the Administrative Agent (or, in the case of the
Posting Facility, the Posting Agent), prior to the date on which the first payment to the Non-U.S. Lender is due hereunder, two copies of (x) in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under
Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, United States Internal Revenue Service Form W-8BEN (together with a certificate substantially in the form of Exhibit Q representing that
such Non-U.S. Lender is not a bank for purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower, any interest payment received by such non-U.S. Lender
under this Agreement or any other Credit Document is not effectively connected with the conduct of a trade or business in the United States and is not a controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), (y) Internal Revenue Service Form W-8BEN or Form W-8ECI, in each case properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S. Federal
withholding tax on payments by the Borrower under this Agreement or (z) if a Non-U.S. Lender does not act or ceases to act for its own account with respect to any portion of any sums paid or payable to such Lender under any of the Credit
Documents (for example, in the case of a typical participation or where Non-U.S. Lender is a pass through entity) Internal Revenue Service Form W-8IMY and all necessary attachments (including the forms described in clauses (x) and
(y) above, as required); and 
 (ii) deliver to the Borrower and the Administrative Agent (or, in the
case of the Posting Facility, the Posting Agent) two further copies of any such form or certification (or any applicable successor form) on or before the date that any such form or certification expires or becomes obsolete and after the occurrence
of any event requiring a change in the most recent form previously delivered by it to the Borrower. 
 If in any such case any Change in Law has
occurred prior to the date on which any such delivery would otherwise be required that renders any such form inapplicable or would prevent such Non-U.S. Lender from duly completing and delivering any such form with respect to it, such Non-U.S.
Lender shall promptly so advise the Borrower and the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent). 

  

#4812-2844-92899582-0297 
 -147- 

 (f) If any Lender, the Administrative Agent, the Posting Agent or the Collateral Agent, as
applicable, determines, in its sole discretion, that it had received and retained a refund of an Indemnified Tax (including an Other Tax) for which a payment has been made by the Borrower pursuant to this Agreement, which refund in the good faith
judgment of such Lender, the Administrative Agent, the Posting Agent or the Collateral Agent, as the case may be, is attributable to such payment made by the Borrower, then the Lender, the Administrative Agent, the Posting Agent or the Collateral
Agent, as the case may be, shall reimburse the Borrower for such amount (net of all out-of-pocket expenses of such Lender, the Administrative Agent, the Posting Agent or the Collateral Agent, as the case may be, and without interest other than any
interest received thereon from the relevant Governmental Authority with respect to such refund) as the Lender, Administrative Agent, the Posting Agent or the Collateral Agent, as the case may be, determines in its sole discretion to be the
proportion of the refund as will leave it, after such reimbursement, in no better or worse position (taking into account expenses or any taxes imposed on the refund) than it would have been in if the payment had not been required; provided
that the Borrower, upon the request of the Lender, the Administrative Agent, the Posting Agent or the Collateral Agent, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Lender, the Administrative Agent, the Posting Agent or the Collateral Agent in the event the Lender, the Administrative Agent, the Posting Agent or the Collateral Agent is required to repay such refund to such
Governmental Authority. A Lender, the Administrative Agent, the Posting Agent or the Collateral Agent shall claim any refund that it determines is available to it, unless it concludes in its sole discretion that it would be adversely affected by
making such a claim. Neither the Lender, the Administrative Agent, the Posting Agent nor the Collateral Agent shall be obliged to disclose any information regarding its tax affairs or computations to any Credit Party in connection with this
clause (f) or any other provision of this Section 5.4. 
 (g) If the Borrower determines that a
reasonable basis exists for contesting a Tax, each Lender or Agent, as the case may be, shall use reasonable efforts to cooperate with the Borrower as the Borrower may reasonably request in challenging such Tax. Subject to the provisions of
Section 2.12, each Lender and Agent agrees to use reasonable efforts to cooperate with the Borrower as the Borrower may reasonably request to minimize any amount payable by the Borrower or any Guarantor pursuant to this
Section 5.4. The Borrower shall indemnify and hold each Lender and Agent harmless against any out-of-pocket expenses incurred by such Person in connection with any request made by the Borrower pursuant to this Section 5.4(g).
Nothing in this Section 5.4(g) shall obligate any Lender or Agent to take any action that such Person, in its sole judgment, determines may result in a material detriment to such Person. 

(h) Each Lender and Agent with respect to any Loan or Posting Advance made to the Borrower that is a United States person under
Section 7701(a)(30) of the Code (each, a “U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) two United States Internal Revenue Service Forms
W-9 (or substitute or successor form), properly completed and duly executed, certifying that such Lender or Agent is exempt from United States backup withholding (i) on or prior to the Closing Date (or on or prior to the date it becomes a party
to this Agreement), (ii) on or before the date that such form expires or becomes obsolete, (iii) after the occurrence of a change in the Agent’s or Lender’s circumstances requiring a change in the most recent form previously
delivered by it to the Borrower and the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) and (iv) from time to time thereafter if reasonably requested by the Borrower or the Administrative Agent (or, in the case
of the Posting Facility, the Posting Agent).

 -148- 

 (i) The agreements in this Section 5.4 shall survive the termination of this
Agreement and the payment of the Loans, Posting Advances and all other amounts payable hereunder. 
 5.5. Computations of
Interest and Fees. 
 (a) Except as provided in the next succeeding sentence, interest on LIBOR Loans, Posting Advances and
ABR Loans shall be calculated on the basis of a 360-day year for the actual days elapsed. Interest on ABR Loans in respect of which the rate of interest is calculated on the basis of the Administrative Agent’s prime rate and interest on overdue
interest shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. 
 (b)
Fees (other than the Maintenance Fee) and the average daily Stated Amount of Letters of Credit shall be calculated on the basis of a 360-day year for the actual days elapsed. 
 (c) The Maintenance Fee shall be calculated by the Posting Calculation Agent in the manner set forth in the Posting Facility Fee Letter. 

(d) Whenever the Posting Calculation Agent makes a determination or calculation under this Agreement or in respect of the transactions
contemplated hereby, the Posting Calculation Agent shall make such determination or calculation (i) in good faith, (ii) in a commercially reasonable manner, (iii) with respect to calculations or determinations involving transaction
valuations, consistent with its practices and procedures for valuing similar transactions and (iv) in consultation with the Borrower. The Borrower may, acting in good faith, dispute a calculation or determination by the Posting Calculation
Agent which it believes is inaccurate (provided that the Borrower shall make any determination or calculation relating to such dispute in a commercially reasonable manner). In the event of such a dispute, the Borrower and the Posting
Calculation Agent shall first endeavor to resolve such dispute. If the Borrower and the Posting Calculation Agent are unable to resolve such dispute within five Business Days, the Borrower and Posting Calculation Agent shall mutually select a dealer
(with respect to commodity related calculations) or a financial institution (with respect to financial calculations) that customarily acts as a calculation agent for similar transactions to act as Posting Calculation Agent with respect to the issue
in dispute. If the Borrower and the Posting Calculation Agent cannot agree on a dealer or financial institution within one Business Day, then each shall appoint a dealer or financial institution and the appointed dealers or financial institutions
shall together appoint a third dealer or financial institution as Posting Calculation Agent for making the relevant determination, and the decision of such Person shall be final and binding upon the parties. The dealers or financial institutions
selected by a party shall not be parties to this Agreement or Affiliates of a party to this Agreement. It is understood and agreed that, for the avoidance of doubt, the Disclaimer for Mark-to-Market Calculation (set forth in Exhibit O hereto)
does not limit the Borrower’s rights under this Section 5.5(d). 
 5.6. Limit on Rate of Interest.

 (a) No Payment Shall Exceed Lawful Rate. Notwithstanding any other term of this Agreement, the Borrower shall not be
obligated to pay any interest or other amounts under or in connection with this Agreement or otherwise in respect of the Obligations in excess of the amount or rate permitted under or consistent with any applicable law, rule or regulation.

 (b) Payment at Highest Lawful Rate. If the Borrower is not obliged to make a payment that it would otherwise be
required to make, as a result of Section 5.6(a), the Borrower shall make such payment to the maximum extent permitted by or consistent with applicable laws, rules and regulations. 

  

#4812-2844-92899582-0297 
 -149- 

 (c) Adjustment if Any Payment Exceeds Lawful Rate. If any provision of this Agreement
or any of the other Credit Documents would obligate the Borrower to make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate that would be prohibited by any Applicable Law, then notwithstanding such
provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by Applicable Law, such adjustment to be effected, to the
extent necessary, by reducing the amount or rate of interest required to be paid by the Borrower to the affected Lender under Section 2.8. 
 (d) Spreading. In determining whether the interest hereunder is in excess of the amount or rate permitted under or consistent with any Applicable Law, the total amount of interest shall be spread
throughout the entire term of this Agreement until its payment in full. 
 (e) Notwithstanding the foregoing, and after giving
effect to all adjustments contemplated thereby, if any Lender shall have received from the Borrower an amount in excess of the maximum permitted by any Applicable Law, then the Borrower shall be entitled, by notice in writing to the Administrative
Agent to obtain reimbursement from that Lender in an amount equal to such excess, and pending such reimbursement, such amount shall be deemed to be an amount payable by that Lender to the Borrower.

the Collateral Agent’s security interest in such Collateral may not be accomplished on or prior to the Closing Date without undue burden or expense and without the taking of any action that goes beyond commercial reasonableness, then the

notice of any such proceedings has been given to the Borrower or any ERISA Affiliate; and no Lien imposed under the Code or ERISA on the assets of the Borrower or any ERISA Affiliate exists (or is reasonably likely to exist) nor has the Borrower or
any ERISA Affiliate been notified in writing that such a Lien will be imposed on the assets of the Parent, US Holdings, the Borrower or any ERISA Affiliate on account of any Plan, except to the extent that a breach of any of the representations,
warranties or agreements in this Section 8.11(a) would not result, individually or in the aggregate, in an amount of liability that would be reasonably likely to have a Material Adverse Effect. No Plan has an Unfunded Current Liability

Lenders (as accompanied by the Administrative Agent) to visit and inspect any of the properties or assets of the Borrower or such Restricted Subsidiary in whomsoever’s possession to the extent that it is within such party’s control to
permit such inspection (and shall use commercially reasonable efforts to cause such inspection to be permitted to the extent that it is not within such party’s control to permit such inspection), and to examine the books and records of the
Borrower and any such Restricted Subsidiary and discuss the affairs, finances and accounts of the Borrower and of any such Restricted Subsidiary with, and be advised as to the same by, its and their officers and independent accountants, all at such
reasonable times and intervals and to such reasonable extent as the Administrative Agent or Required Lenders may desire (and subject, in the case of any such meetings or advice from such independent accountants, to such accountants’ customary
policies and procedures); provided that, excluding any such visits and inspections during the continuation of an Event of Default (a) only the Administrative Agent, whether on its own or in conjunction with the Required Lenders, may

 9.3. Maintenance of Insurance. The Borrower will, and will cause each
Material Subsidiary that is a Restricted Subsidiary to, at all times maintain in full force and effect, pursuant to self-insurance arrangements or with insurance companies that the Borrower believes (in the good faith judgment of the management of
the Borrower, as applicable) are financially sound and responsible at the time the relevant coverage is placed or renewed, insurance in at least such amounts (after giving effect to any self-insurance which the Borrower believes (in the good faith
judgment of management of the Borrower, as applicable) is reasonable and prudent in light of the size and nature of its business) and against at least such risks (and with such risk retentions) as the Borrower believes (in the good faith judgment of
management of the Borrower, as applicable) is reasonable and prudent in light of the size and nature of its business; and will furnish to the Administrative Agent, upon written reasonable request from the Administrative Agent, information presented
in reasonable detail as to the insurance so carried. With respect to each Mortgaged Property, obtain flood insurance in such total amount as the Administrative Agent may from time to time require, if at any time the area in which any improvements
located on any Mortgaged Property is designated a “flood hazard area” in any Flood Insurance Rate Map published by the Federal Emergency Management Agency (or any successor agency), and otherwise comply with the National Flood Insurance

(a) The Borrower will not, and will not permit the Restricted Subsidiaries to, prepay, repurchase or redeem or otherwise defease any
Permitted Additional Debt that is subordinated to the Obligations or any Existing Notes with Stated Maturities beyond the latest2014 Term Loan Maturity Date of any Credit Facility under the Agreement (the
“Limited Notes”), but in any event, in all cases, excluding any Existing Tender Offer Notes; provided, however, that so long as no Default or Event of Default shall have occurred and be continuing on the date of such
prepayment, repurchase, redemption or other defeasance or would result therefrom, the Borrower and the Restricted Subsidiaries may prepay, repurchase or redeem or otherwise defease such Permitted Additional Debt or such Limited Notes (i) in an
aggregate amount from the Closing Date, when aggregated with (A) the aggregate amount of dividends paid pursuant to Section 10.6(c) from the Closing Date and (B) all (I) Investments made pursuant to
Section 10.5(v) and (II) loans and advances to any direct or indirect parent of the Borrower made pursuant to Section 10.5(m), not in excess of the sum of (1) $500,000,000 plus (2) the Applicable Equity

such prepayment, repurchase, redemption or defeasance, the Applicable Amount at the time of such prepayment, repurchase, redemption or other defeasance; (ii) in the case of Permitted Additional Debt, with the proceeds of other Permitted

intercompany subordinated Indebtedness (including under the Intercompany Subordinated Note) owed among the Borrower and/or the Restricted Subsidiaries, in either case unless a Default or an Event of Default has occurred and
is continuing and the Borrower has received a notice from the Collateral Agent instructing it not to make or permit any such repayment or prepayment or (B) transfers of credit positions in connection with intercompany debt restructurings so
long as such Indebtedness is permitted by Section 10.1 after giving effect to such transfer. For the avoidance of doubt, nothing in this Section 10.7 shall restrict the making of any prepayment of accrued but unpaid interest
and/or original issue discount in respect of either the Borrower Senior Facility or any Refinanced Bridge Indebtedness Documentation in accordance with “Optional Interest Repayment” provisions thereof at the end of any accrued period
ending after the fifth anniversary of the Closing Date. 
 (b) The Borrower will not, and will not permit to the Restricted
Subsidiaries to waive, amend, modify, terminate or release any Permitted Additional Debt that is subordinated to the Obligations, any Limited Notes or the Borrower Senior Interim Loan Agreement, in each case, that to the extent that any such waiver,
amendment, modification, termination or release, taken as a whole, would be adverse to the Lenders in any material respect. 

(c) An Incremental Amendment or Extension Amendment may provide, without the consent of any other Lender required, for
restrictions similar and in addition to those set forth in this Section 10.7 on prepayment, repurchase, redemption, other defeasance, waiver, amendment, modification, termination or release of Indebtedness which matures on or after the 2014
Term Loan Maturity Date but on or before the final maturity date for the Incremental Term Loans, Incremental Deposit L/C Loans, New Revolving Credit Commitments or Extended Loans/Commitments provided for in such Incremental Amendment or Extension
Amendment, as the case may be.

Exchange Notes are issued pursuant to Section 10.1(z) for the purpose of consummating a Permitted Debt Exchange, (i) the Borrower will not, and will not permit any Restricted Subsidiary to, prepay, repurchase, redeem or otherwise defease
or acquire any Permitted Debt Exchange Notes unless the Borrower shall concurrently voluntarily prepay Term Loans pursuant to Section 5.1 on a pro rata basis among the Class or

 -196- 

 
Classes of Term Loans from which such Permitted Debt Exchange Notes were exchanged, in an amount not less than the product of (a) a fraction, the numerator of which is the aggregate
principal amount (calculated on the face amount thereof) of such Permitted Debt Exchange Notes that are proposed to be prepaid, repurchased, redeemed, defeased or acquired and the denominator of which is the aggregate principal amount (calculated on
the face amount thereof) of all Permitted Debt Exchange Notes in respect of the relevant Permitted Debt Exchange then outstanding (prior to giving effect to such proposed prepayment, repurchase, redemption, defeasance or acquisition) and
(b) the aggregate principal amount (calculated on the face amount thereof) of Term Loans of the Class or Classes from which such Permitted Debt Exchange Notes were exchanged then outstanding and (ii) the Borrower will not waive, amend or
modify the terms of any Permitted Debt Exchange Notes or any indenture pursuant to which such Permitted Debt Exchange Notes have been issued in any manner inconsistent with the terms of Section 2.17(a), 10.1(z) or the definition of
“Permitted Other Notes” or that would result in a Default hereunder if such Permitted Debt Exchange Notes (as so amended or modified) were then being issued or incurred. 

10.8. Limitations on Sale Leasebacks. The Borrower will not, and will not permit the Restricted Subsidiaries to, enter into or
effect any Sale Leasebacks after the Closing Date, other than Permitted Sale Leasebacks.

Posting Advance, or the issuance of a Letter of Credit and the form and substance of all evidence delivered in connection with establishing the satisfaction of each such condition; and 

(iv) the adequacy, accuracy and/or completeness of any information delivered by the Administrative Agent, the Posting
Agent, any other Lender or by any of their respective Related Parties under or in connection with this Agreement or any other Credit Document, the transactions contemplated hereby and thereby or any other agreement, arrangement or document entered
into, made or executed in anticipation of, under or in connection with any Credit Document. 
 12.4. Reliance by Agents.
The Administrative Agent, the Posting Agent and the Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex, electronic mail,
or teletype message, statement, order or other document or instruction 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 US Holdings and/or the Borrower), independent accountants and other experts selected by the Administrative Agent, the Posting Agent or the Collateral Agent. The Administrative Agent and the Posting Agent may deem and treat the Lender specified in
the Register with respect to any amount owing hereunder as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent and the Posting Agent. The
Administrative Agent, the Posting Agent and the Collateral Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Credit Document unless it shall first receive such advice or concurrence of the
Required Lenders (or the Required Posting Lenders, as applicable) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or
continuing to take any such action. The Administrative Agent, the Posting Agent and the Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Credit Documents in accordance
with a request of the Required Lenders (or the 

  

#4812-2844-92899582-0297 
 -205- 

 
Required Posting Lenders, as applicable), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans and/or
Posting Advances; provided that the Administrative Agent, the Posting Agent and Collateral Agent shall not be required to take any action that, in its opinion or in the opinion of its counsel, may expose it to liability or that is contrary to
any Credit Document or Applicable Law. For purposes of determining compliance with the conditions specified in Sections 6 and 7 on the Closing Date, 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 Administrative Agent shall have received notice from such Lender
prior to the proposed Closing Date specifying its objection thereto. 
 12.5. Notice of Default. Neither the
Administrative Agent, the Posting Agent nor the Collateral Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent, the Posting Agent or Collateral Agent, as
applicable, has received notice from a Lender, US Holdings or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Administrative
Agent or the Posting Agent receives such a notice, it shall give notice thereof to the Lenders, the Administrative Agent, the Posting Agent and the Collateral Agent. The Administrative Agent and the Posting Agent shall take such action with respect
to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or Required Posting Lenders, as applicable); provided that unless and until the Administrative Agent or the Posting Agent shall have received such
directions, the Administrative Agent and the Posting Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as is within its authority to take under this
Agreement and otherwise as it shall deem advisable in the best interests of the Lenders except to the extent that this Agreement requires that such action be taken only with the approval of the Required Lenders (or the Required Posting Lenders, as
applicable) or each of the Lenders, as applicable. 
 12.6. Non-Reliance on Administrative Agent, the Posting Agent,
Collateral Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent, the Posting Agent nor the Collateral Agent nor any of their respective officers, directors, employees, agents, attorneys-in-fact or
Affiliates has made any representations or warranties to it and that no act by the Administrative Agent, the Posting Agent or Collateral Agent hereinafter taken, including any review of the affairs of US Holdings, the Borrower, any other Guarantor
or any other Credit Party, shall be deemed to constitute any representation or warranty by the Administrative Agent, the Posting Agent or Collateral Agent to any Lender or the Letter of Credit Issuer. Each Lender and the Letter of Credit Issuer
represents to the Administrative Agent, the Posting Agent and the Collateral Agent that it has, independently and without reliance upon the Administrative Agent, Collateral Agent, the Posting Agent or any other Lender, and based on such documents
and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of US Holdings, the Borrower, each other Guarantor and each other
Credit Party and made its own decision to make its Loans and/or Posting Advances hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent, Collateral Agent,
the Posting Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and
the other Credit Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of US Holdings, the Borrower, each other Guarantor and
each other Credit Party. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent or the Posting Agent hereunder, neither the Administrative Agent, the Posting Agent nor the
Collateral Agent shall have any duty or responsibility to provide any Lender with any credit or other 

  

#4812-2844-92899582-0297 
 -206- 

 
information concerning the business, assets, operations, properties, financial condition, prospects or creditworthiness of US Holdings, the Borrower, any other Guarantor or any other Credit Party
that may come into the possession of the Administrative Agent, the Posting Agent or Collateral Agent any of their respective officers, directors, employees, agents, attorneys-in-fact or Affiliates. 

12.7. Indemnification. The Lenders agree to indemnify each Agent, each in its capacity as such (to the extent not reimbursed by
the Credit Parties and without limiting the obligation of the Credit Parties to do so), ratably according to their respective portions of the Total Credit Exposure in effect on the date on which indemnification is sought (or, if indemnification is
sought after the date upon which the Commitments shall have terminated and the Loans and Posting Advances shall have been paid in full, ratably in accordance with their respective portions of the Total Credit Exposure in effect immediately prior to
such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time occur (including at any time following the payment
of the Loans and the Posting Advances) be imposed on, incurred by or asserted against such Agent, including all fees, disbursements and other charges of counsel to the extent required to be reimbursed by the Credit Parties pursuant to
Section 13.5, in any way relating to or arising out of the Commitments, this Agreement, any of the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by such Agent under or in connection with any of the foregoing (SUBJECT TO THE PROVISO BELOW, WHETHER OR NOT CAUSED BY OR ARISING IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY OR SOLE ORDINARY NEGLIGENCE
OF THE INDEMNIFIED PARTY); provided that no Lender shall be liable to any Agent for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from such Agent’s gross negligence or willful misconduct as determined by a final judgment of a court of competent jurisdiction; provided, further, that no action taken in accordance with the directions of the Required
Lenders (or such other number or percentage of the Lenders as shall be required by the Credit Documents) shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 12.7. In the case of any
investigation, litigation or proceeding giving rise to any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time occur, be imposed upon, incurred
by or asserted against the Administrative Agent, the Posting Agent or the Collateral Agent in any way relating to or arising out of the Commitments, this Agreement, any of the other Credit Documents or any documents contemplated by or referred to
herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing (including at any time following the payment of the Loans and Posting Advances), this
Section 12.7 applies whether any such investigation, litigation or proceeding is brought by any Lender or any other Person. Without limitation of the foregoing, each Lender shall reimburse such Agent upon demand for its ratable share of
any costs or out-of-pocket expenses (including attorneys’ fees) 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 rendered in respect of rights or responsibilities under, this Agreement, any other Credit Document, or any document contemplated by or referred to herein, to the extent that such Agent is not reimbursed
for such expenses by or on behalf of the Borrower; provided that such reimbursement by the Lenders shall not affect the Borrower’s continuing reimbursement obligations with respect thereto. If any indemnity furnished to any Agent for any
purpose shall, in the opinion of such Agent, be insufficient or become impaired, such Agent may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished;
provided in no event shall this sentence require any Lender to indemnify any Agent against any liability, obligation, loss, damage, penalty, action, judgment, suit, cost, expense or disbursement in excess of such Lender’s pro rata
portion thereof; and provided further, this sentence shall not be deemed to require any Lender to indemnify any Agent against any liability, obligation, loss, damage, penalty, action,

  

#4812-2844-92899582-0297 
 -207- 

 
judgment, suit, cost, expense or disbursement resulting from such Agent’s gross negligence or willful misconduct (as determined by a final judgment of court of competent jurisdiction). The
agreements in this Section 12.7 shall survive the payment of the Loans, the Posting Advances and all other amounts payable hereunder. 
 12.8. Agents in its Individual Capacities. Each Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with US Holdings, the Borrower, any
other Guarantor, and any other Credit Party as though such Agent were not an Agent hereunder and under the other Credit Documents. With respect to the Loans or Posting Advances made by it, each Agent shall have the same rights and powers under this
Agreement and the other Credit Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent in its individual capacity. 

12.9. Successor Agents. (a) Each of the Administrative Agent and Collateral Agent may resign at any time by notifying the
other Agent, the Lenders, the Letter of Credit Issuers and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, subject to the consent of the Borrower (not to be unreasonably withheld or delayed),
to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may on behalf of the Lenders and the Letter of Credit Issuers, appoint a successor Agent meeting the qualifications set forth
above; provided that if such Agent shall notify the Borrower and the Lenders that no qualifying person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (x) the
retiring Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the Secured Parties under any of the
Credit Documents, the retiring Collateral Agent shall continue to hold such collateral security until such time as a successor Collateral Agent is appointed) and (y) all payments, communications and determinations provided to be made by, to or
through such Agent shall instead be made by or to each Lender and the Letter of Credit Issuer directly, until such time as the Required Lenders with (except after the occurrence and during the continuation of a Default or Event of Default) the
consent of the Borrower (not to be unreasonably withheld) appoint successor Agents as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as the Administrative Agent or Collateral Agent, as the case may be,
hereunder, and upon the execution and filing or recording of such financing statements, or amendments thereto, and such amendments or supplements to the Mortgages, and such other instruments or notices, as may be necessary or desirable, or as the
Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Security Documents, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of
the retiring (or retired) Agent, and the retiring Agent shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this Section). The fees
payable by the Borrower (following the effectiveness of such appointment) to such Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Agent’s
resignation hereunder and under the other Credit Documents, the provisions of this Section 12 (including 12.7) and Section 13.5 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their
respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Agent was acting as an Agent. 
 (b) Without limitation to Section 3.6(a) or 13.9, any resignation by Citibank, N.A. as Administrative Agent pursuant to this Section 12.9 shall also constitute its
resignation as a Letter of Credit Issuer and Swingline Lender. Upon the acceptance of a successor’s appointment as Administrative Agent 

  

#4812-2844-92899582-0297 
 -208- 

 
hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Letter of Credit Issuer and Swingline Lender,
(b) the retiring Letter of Credit Issuer and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Credit Documents, and (c) the successor Letter of Credit Issuer shall issue
letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Letter of Credit Issuer to effectively assume the obligations of the retiring
Letter of Credit Issuer with respect to such Letters of Credit. 
 (c) The Posting Agent may resign at any time by giving 30
days’ prior written notice to the Posting Lenders and the Borrower. Upon any such resignation, the Required Posting Lenders shall have the right to appoint a successor Posting Agent acceptable to the Borrower. If no successor shall have been so
appointed by the Required Posting Lenders and shall have accepted such appointments within 30 days after the Posting Agent gives notice of its resignation, then the Posting Agent may, on behalf of the Posting Lenders, appoint a successor Posting
Agent, having a combined capital and surplus of at least $500,000,000 or an Affiliate of any such bank and in any case, the Posting Agent’s resignation shall become effective on the 30th day after such notice of resignation. If neither the
Required Posting Lenders nor the Posting Agent shall have appointed a successor Posting Agent within 30 days of the date of such notice of resignation, the Required Posting Lenders shall be deemed to succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Posting Agent until such time as the Required Posting Lenders appoint a successor Posting Agent in accordance with this paragraph and such successor Posting Agent accepts such appointment. Upon the
acceptance of any appointment as Posting Agent hereunder by a successor bank (or the Required Posting Lenders have been deemed to succeed the retiring Posting Agent pursuant to the immediately preceding sentence), such successor shall succeed to and
become vested with all the rights, powers, privileges and duties of the retiring Posting Agent and the Posting Agent shall be discharged from its duties and obligations hereunder. After the Posting Agent’s resignation hereunder, the provisions
of this paragraph and Sections 12.7, 13.5 and 14.11 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Posting Agent. The Posting Calculation
Agent and the Posting Lenders agree that unless the Borrower otherwise consents in writing, the Posting Calculation Agent may not resign as the Posting Calculation Agent. 
 12.10. Withholding Tax. To the extent required by any Applicable Law, the Administrative Agent (or, with respect to the Posting Facility, the Posting Agent) may withhold from any interest payment
to any Lender an amount equivalent to any applicable withholding tax. If the Internal Revenue Service or any authority of the United States or other jurisdiction asserts a claim that the Administrative Agent (or, with respect to the Posting
Facility, the Posting Agent) did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered, was not properly executed, or because such Lender failed to notify the Administrative
Agent or (or, with respect to the Posting Facility, the Posting Agent) of a change in circumstances that rendered the exemption from, or reduction of, withholding tax ineffective, or for any other reason), such Lender shall indemnify the
Administrative Agent (or, with respect to the Posting Facility, the Posting Agent) (to the extent that the Administrative Agent (or, with respect to the Posting Facility, the Posting Agent) has not already been reimbursed by the Borrower (solely to
the extent required by this Agreement) and without limiting the obligation of the Borrower to do so) fully for all amounts paid, directly or indirectly, by the Administrative Agent (or, with respect to the Posting Facility, the Posting Agent) as tax
or otherwise, including penalties and interest, together with all expenses incurred, including legal expenses, allocated staff costs and any out of pocket expenses. 
 12.11. Trust Indenture Act. In the event that Citibank, N.A. or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust
Indenture 

  

#4812-2844-92899582-0297 
 -209- 

 
Act”) in respect of any securities issued or guaranteed by any Credit Party, and agree that any payment or property received in satisfaction of or in respect of any Obligation of such
Credit Party hereunder or under any other Credit Document by or on behalf of Citibank, N.A., in its capacity as the Administrative Agent or the Collateral Agent for the benefit of any Lender or Secured Party under any Credit Document (other than
Citibank, N.A. or an Affiliate of Citibank, N.A.) and which is applied in accordance with the Credit Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of
the Trust Indenture Act. 
 12.12. Intercreditor Agreement. The Collateral Agent is hereby authorized to enter into the
Intercreditor Agreement, and the parties hereto acknowledge that the Intercreditor Agreement is binding upon them. Each Lender (a) hereby agrees that it will be bound by and will take no actions contrary to the provisions of the Intercreditor
Agreement and (b) hereby authorizes and instructs the Collateral Agent to enter into the Intercreditor Agreement and to subject the Liens on the Collateral securing the Obligations to the provisions thereof. In addition, each Lender hereby
authorizes the Collateral Agent to enter into (i) any amendments to the Intercreditor Agreement and (ii) any other intercreditor arrangements, in the case of clauses (i) and (ii) to the extent required to give
effect to the establishment of intercreditor rights and privileges as contemplated and required by Section 10.2 of this Agreement. 
 12.13. Security Documents and Guarantee. (a) Agents under Security Documents and Guarantee. Each Secured Party hereby further authorizes the Administrative Agent or Collateral Agent, as
applicable, on behalf of and for the benefit of the Secured Parties, to be the agent for and representative of the Secured Parties with respect to the Collateral and the Security Documents. Subject to Section 13.1, without further
written consent or authorization from any Secured Party, the Administrative Agent or Collateral Agent, as applicable, may execute any documents or instruments necessary to in connection with a sale or disposition of assets permitted by this
Agreement, (i) release any Lien encumbering any item of Collateral that is the subject of such sale or other disposition of assets, or with respect to which Required Lenders (or such other Lenders as may be required to give such consent under
Section 13.1) have otherwise consented or (ii) release any Guarantor from the Guarantee, or with respect to which Required Lenders (or such other Lenders as may be required to give such consent under Section 13.1) have
otherwise consented. 
 (b) Right to Realize on Collateral and Enforce Guarantee. Anything contained in any of the Credit
Documents to the contrary notwithstanding, US Holdings, the Borrower, the Agents and each Secured Party hereby agree that (i) no Secured Party shall have any right individually to realize upon any of the Collateral or to enforce the Guarantee,
it being understood and agreed that all powers, rights and remedies hereunder may be exercised solely by the Administrative Agent, on behalf of the Lenders in accordance with the terms hereof and all powers, rights and remedies under the Security
Documents and Guarantee may be exercised solely by the Collateral Agent, on behalf of the Secured Parties, and (ii) in the event of a foreclosure by the Collateral Agent on any of the Collateral pursuant to a public or private sale or other
disposition, the Collateral Agent or any Secured Party may be the purchaser or licensor of any or all of such Collateral at any such sale or other disposition and the Collateral Agent, as agent for and representative of the Secured Parties (but not
any Lender or Lenders in its or their respective individual capacities unless Required Lenders shall otherwise agree in writing) shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any
portion of the Collateral sold at any such public sale, to use and apply any of the Obligations as a credit on account of the purchase price for any collateral payable by the Collateral Agent at such sale or other disposition.

shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement or any other Credit Document; provided that such agreement or
instrument may provide that such Lender will not, without the consent of the Participant, agree to any consent, amendment, modification, supplement or waiver described in clauses (i) or (vii) of the second proviso of the

2.11 and 5.4 to the same extent as if it were a Lender, and provided that such Participant agrees to be subject to the requirements of those Sections as though it were a Lender and had acquired its interest by assignment pursuant to
clause (b) of this Section 13.6 To the extent permitted by Applicable Law, each Participant also shall be entitled to the benefits of Section 13.8(b) as though it were a Lender; provided such Participant

amounts of each participant’s interest in the Loans or Posting Advances (or other rights or obligations) held by it (the “Participant Register”). The entries in the Participant Register shall be conclusive, and such lender
shall treat each Person whose name is recorded in the Participant Register as the owner of such Loan, Posting Advance or other obligation hereunder as the owner thereof for all purposes of this Agreement notwithstanding any notice to the contrary.
Any such Participant Register shall be available for inspection by the Administrative Agent, the Posting Agent and the Borrower at any reasonable time and from time to time upon reasonable prior notice. 

(d) Any Lender may, without the consent of US Holdings, the Borrower, the Administrative Agent or the Posting Agent, 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 pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 13.6 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 pledgee or assignee for
such Lender as a party hereto. In order to facilitate such pledge or assignment or for any other reason, the Borrower hereby agrees that, upon request of any Lender at any time and from time to time after any Borrower has made its initial borrowing
hereunder, the Borrower shall provide to such Lender, at the Borrower’s own expense, a promissory note, substantially in the form of Exhibit K-1,1-A, K-1-B, K-2-A, K-2-B,

relating to Loans or Posting Advances made hereunder any and all financial information in such Lender’s possession concerning the Borrower and its Affiliates that has been delivered to such Lender by or on behalf of the Borrower and its

becoming a party to this Agreement. 
 (f) The words “execution,” “signed,” “signature,” and words
of like import in any Assignment and Acceptance shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed
signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic
Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. 
 (g) SPV
Lender. Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (a “SPV”), identified as such in writing from time to time by
the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make the Borrower pursuant to this Agreement;
provided that (i) nothing herein shall constitute a commitment by any SPV to make any Loan and (ii) if an SPV elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall
be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPV hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto
hereby agrees that no SPV shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which
agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPV, it shall not institute against, or
join any other person in instituting against, such SPV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary
contained in this Section 13.6, any SPV may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its
interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance
of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPV. This
Section 13.6(g) may not be amended without the written consent of the SPV. Notwithstanding anything to the contrary in this Agreement, (x) no SPV shall be entitled to any greater rights under Sections 2.10, 2.11, and
5.4 than its Granting Lender would have been entitled to absent the use of such SPV and (y) each SPV agrees to be subject to the requirements of Sections 2.10, 2.11, and 5.4 as though it were a Lender and has
acquired its interest by assignment pursuant to clause (b) of this Section 13.6. 

(h) Contribution and Cancellation. Upon any contribution of Term Loans or Deposit L/C Loans to the Borrower or any
Restricted Subsidiary (including pursuant to a Permitted Debt Exchange), (A) the aggregate principal amount (calculated on the face amount thereof) of such Loans shall automatically be cancelled and retired by the Borrower on the date of the
contribution thereof (and, if requested by the Administrative Agent, any applicable contributing Lender shall execute and deliver to the Administrative Agent an Assignment and Acceptance, or such other form as may be reasonably requested by the
Administrative Agent, in respect thereof pursuant to which the respective Lender assigns its interest in such Loans to the Borrower for immediate cancellation) and (B) the Administrative Agent shall record such cancellation and retirement in
the Register.

replacement bank or institution shall purchase, at par) all Loans, Posting Advances and other amounts (other than any disputed amounts), pursuant to Section 2.10, 2.11, 3.5 or 5.4, as the case may be) owing to such
replaced Lender prior to the date of replacement, (iv) the replacement bank or institution, if not already a Lender, and the terms and conditions of such replacement, shall be reasonably satisfactory to the Administrative Agent (or, in the case
of any Posting Lender, the Posting Agent), (v) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 13.6 (provided that the Borrower shall be obligated to pay the
registration and processing fee referred to therein) and (vi) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent, the Posting Agent or any other Lender shall have against the
replaced Lender. 
 (b) If any Lender (such Lender, a “Non-Consenting Lender”) has failed to consent to a
proposed amendment, modification, supplement, waiver, discharge or termination that pursuant to the terms of Section 13.1 requires the consent of all of the Lenders or all Lenders affected and with respect to which the Required Lenders
(or the Required Posting Lenders, as applicable) shall have granted their consent, then provided no Event of Default then exists, the Borrower shall have the right (unless such Non-Consenting Lender grants such consent) to replace such
Non-Consenting Lender by requiring such Non-Consenting Lender to assign its Loans, Posting Advances and its Commitments hereunder to one or more assignees reasonably acceptable to the Administrative Agent or, with respect to the Posting Facility,
the Posting Agent; provided that: (a) all Obligations of the Borrower owing to such Non-Consenting Lender being replaced shall be paid in full to such Non-Consenting Lender concurrently with such assignment, and (b) the replacement
Lender shall purchase the foregoing by paying to such Non-Consenting Lender a price equal to the principal amount thereof plus accrued and unpaid interest thereon. In connection with any such assignment, the Borrower, Administrative Agent,
the Posting Agent, such Non-Consenting Lender and the replacement Lender shall otherwise comply with Section 13.6. 

13.8. Adjustments; Set-off. 
 (a) If any Lender (a “benefited Lender”) shall at any time receive any payment of all or part of its Loans or Posting Advances, or interest thereon, or receive any collateral in respect
thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 11.5, or otherwise), in a greater proportion than any such payment to or collateral received by any other
Lender, if any, in respect of such other Lender’s Loans or Posting Advances, or interest thereon, such benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s
Loan or Posting Advance, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefited Lender to share the excess payment or benefits of such collateral or
proceeds ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Lender, such purchase shall be rescinded, and the purchase price
and benefits returned, to the extent of such recovery, but without interest.

branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such set-off and application made by such Lender; provided that the
failure to give such notice shall not affect the validity of such set-off and application.

 SECTION 14. Posting Facility. 

14.1. [Reserved]. 
 14.2. Computation of MTM Exposure. 
 (a) By no later than 9:00 p.m. (New
York time) on each Business Day (unless it has been prevented from doing so due to a technical delay or failure (which shall not include a delay or failure that could have been reasonably avoided or for which alternative provision could reasonably
have been made) or as a result of a Market Disruption Event), the Posting Calculation Agent shall determine the MTM Exposure as of the close of business on such Business Day. Promptly after making such determination, it shall advise the Posting
Agent and the Borrower of that determination in a form substantially similar to Exhibit P (each, a “Daily Notice”) (which Daily Notice shall be provided via email to the addresses of the Borrower and the Posting Agent set
forth on Schedule 13.2). If a Market Disruption Event has occurred, then the Posting Calculation Agent shall, as promptly as reasonably practicable, determine the MTM Exposure in accordance with the Disruption Fallbacks and any other relevant
provisions of the Commodity Definitions. If such determination is prevented due to a technical delay or failure described above, the Posting Calculation Agent shall make such determination as promptly as reasonably practicable after such matter is
remedied. 
 (b) After 5:00 p.m. (New York time), on any Business Day, the Posting Calculation Agent shall endeavor, in a
commercially reasonable manner, to estimate (based on such factors and information as it deems reasonably relevant and are then available to it) the MTM Exposure for such Business Day (the “Estimated MTM Exposure”) and provide the
same to the Borrower and the Posting Agent (via email to the addresses of the Borrower and the Posting Agent set forth on Schedule 13.2); 

  

#4812-2844-92899582-0297 
 -229- 

 
provided that (i) the Posting Calculation Agent shall not be required to provide such Estimated MTM Exposure within any specified time period, (ii) the Borrower acknowledges that the
Estimated MTM Exposure for any Business Day may differ significantly from the actual MTM Exposure determined by the Posting Calculation Agent for that Business Day pursuant to clause (a) above (the “Actual MTM Exposure”),
(iii) that any difference between the Estimated MTM Exposure and the Actual MTM Exposure for any Business Day shall in no way limit or diminish the obligations of the Borrower, the Posting Agent, the Posting Lenders or the Posting Calculation
Agent hereunder, which shall be based on the Actual MTM Exposure, (iv) the Borrower shall be solely responsible for whether and the extent to which it makes use of any Estimated MTM Exposure it receives and shall have no claim of any nature
against the Posting Calculation Agent, the Posting Agent or any Lender as a result of or based on its use of such Estimated MTM Exposure or any difference between the Estimated MTM Exposure and the Actual MTM Exposure for any Business Day and
(v) that the Posting Calculation Agent shall not be required, and shall have no obligation, to provide any backup data or other information supporting or reconciling any differences between an Estimate MTM Exposure and an Actual MTM Exposure.

 (c) Without limiting clauses (a) and (b) above, the Borrower acknowledges that each Daily Notice and
each Estimated MTM Exposure provided by the Posting Calculation Agent shall include, and be subject to, the Posting Calculation Agent’s standard disclaimer relating to mark-to-market calculations, a copy of which is set forth in Exhibit O
hereto. 
 14.3. Computation of Posting Advance Amounts or Posting Repayment Amounts. 

(a) The Posting Calculation Agent shall calculate the MTM Exposure as of the close of business on the Business Day immediately preceding
the Closing Date (the “Closing Date MTM Exposure”) and shall provide the same to the Borrower in writing no later than 9:00 p.m. (New York time) on the day preceding the Closing Date. The amount of the Posting Advance to be made on
the Closing Date shall equal the Closing Date MTM Exposure (the “Initial Posting Advance Amount”). 
 (b) On
each Computation Date, the Posting Calculation Agent shall determine the amount by which the MTM Exposure for that Computation Date is greater than or less than the Aggregate Posting Advances Outstanding as of that Computation Date. If such MTM
Exposure exceeds such Aggregate Posting Advances Outstanding, then such excess (rounded up or down to the nearest integral multiple of $100,000) shall be the “Posting Advance Amount” for that Computation Date and the related Posting
Advance Date. If such Aggregate Posting Advances Outstanding exceed such MTM Exposure, then such excess (rounded up or down to the nearest integral multiple of $100,000) shall be the “Posting Repayment Amount” for that Computation
Date and the related Posting Repayment Date. 
 (c) By no later than 9:00 p.m. (New York time), on each Computation Date (unless
it has been prevented from doing so due to a technical delay or failure (which shall not include a delay or failure that could have been reasonably avoided or for which alternative provision could reasonably have been made) or as a result of a
Market Disruption Event), the Posting Calculation Agent shall notify the Posting Agent and the Borrower of the Posting Advance Amount or Posting Repayment Amount (as applicable) for such Computation Date, which shall be included in, if applicable,
the Daily Notice for that date (and may be provided via email to the addresses of the Borrower and the Posting Agent set forth on Schedule 13.2). 
 (d) If the Daily Notice for any Computation Date specifies a Posting Repayment Amount, then by no later than 10:00 a.m. (New York time) on the first Business Day after such Daily Notice has been given,
the Borrower may advise the Posting Agent that it has elected to repay such Posting Repayment Amount on the first Business Day following such Computation Date and such Posting Repayment Amount shall be due on such date.

 14.4. Posting Advances Amounts. 

(a) Subject to the terms and conditions herein set forth, each Posting Lender, severally, and not jointly, agrees to make a Posting
Advance in Dollars on the Closing Date to the Borrower in an amount equal to such Posting Lender’s Posting Percentage (based on its Posting Commitment) of the Initial Posting Advance Amount. 

(b) Subject to the terms and conditions herein set forth, each Posting Lender, severally, and not jointly, agrees to make a Posting
Advance in Dollars on each Posting Advance Date (other than the Closing Date) to the Borrower in an amount equal to such Posting Lender’s Posting Percentage of the Posting Advance Amount for that Posting Advance Date. 

(c) No later than 2:00 p.m. (New York time) on each Posting Advance Date, each Posting Lender will make available its Posting Percentage
of each Borrowing of Posting Advances to be made on such date in the manner provided below; provided, further, that on the Closing Date, such funds may be made available at such earlier time as may be agreed among the Posting Lenders,
the Borrower and the Posting Agent. 
 (d) Each Posting Lender shall make available all amounts it is to make available to the
Borrower under any Borrowing of Posting Advances for its applicable Commitments in immediately available funds pursuant to the Payment Instructions (subject to any alternative Payment Instructions or netting and/or settlement agreements as in effect
from time to time), to the Posting Agent, and the Posting Agent will apply such amounts in accordance with the Payment Instructions. Unless the Posting Agent shall have been notified by any Posting Lender prior to the date of any such Borrowing of
such Posting Advances that such Lender does not intend to make available to the Posting Agent such Lender’s portion of the Borrowing of such Posting Advances to be made on such date, the Posting Agent may assume that such Lender has made such
amount available to the Posting Agent on such date of such Borrowing, and the Posting Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrower on such date a
corresponding amount. If such corresponding amount is not in fact made available to the Posting Agent by such Lender and the Posting Agent has made available such amount to the Borrower, the Posting Agent shall be entitled to recover such
corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Posting Agent’s demand therefor the Posting Agent shall promptly notify the Borrower and the Borrower shall immediately pay such
corresponding amount to the Posting Agent in Dollars. The Posting Agent shall also be entitled to recover from such Lender or the Borrower interest on such corresponding amount in respect of each day from the date such corresponding amount was made
available by the Posting Agent to the Borrower to the date such corresponding amount is recovered by the Posting Agent, at a rate per annum equal to (i) if paid by such Lender, the Overnight Rate or (ii) if paid by the Borrower, the
then-applicable rate of interest or fees, calculated in accordance with Section 2.8, for the respective Posting Advances. If such Lender shall repay to the Posting Agent such corresponding amount, such amount shall constitute such
Lender’s portion of such Posting Advance for purposes of this Agreement. 
 (e) Nothing in this Section 14.4
shall be deemed to relieve any Posting Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender hereunder (it being understood,
however, that no Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder). 

  

#4812-2844-92899582-0297 
 -231- 

 (f) Each Posting Advance shall be made by the Posting Lenders pro rata in accordance with
their then-applicable Posting Commitments; provided, however, that the failure of any Lender to make any Posting Advance shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however,
that no Lender shall be responsible for the failure of any other Lender to make any Posting Advance required to be made by such other Lender). 
 14.5. Posting Repayment Amounts by the Borrower. 
 (a)
On each Posting Repayment Date, the Borrower shall repay to the Posting Agent, for the benefit of the Posting Lenders an amount equal to the Posting Repayment Amount for that Posting Repayment Date; provided, however, that at any time that
the Posting Lender and the Dealer are not Affiliates, the Borrower shall not be required to repay any Posting Repayment Amount to any Posting Lender while such Posting Lender is a Defaulting Lender until the earlier of (i) the 60th day following the date such Posting Repayment Amount is due and
(ii) two Business Days following the date upon which such Posting Lender ceases to be a Defaulting Lender. 
 (b) On the
Posting Facility Maturity Date, the Borrower shall repay to the Lenders the Aggregate Posting Advances Outstanding. 
 14.6.
Payment Instructions; Netting and/or Settlement Agreements. 
 (a) From time to time, the Borrower may establish with the
Posting Agent Payment Instructions regarding the making of Posting Advances hereunder. So long as any such Payment Instruction remains in effect, the terms thereof shall supersede any conflicting terms set forth herein. 

(b) From time to time, the Borrower may request that the Posting Agent, on behalf of the Posting Lenders, enter into netting and/or
settlement agreements with the Dealer in order to facilitate the timely payment of amounts payable to or from the Lenders hereunder and to or from the Dealer. So long as any such payment netting and/or settlement arrangement remains in effect, the
terms thereof shall supersede any conflicting terms set forth herein. 
 14.7. Deemed Transactions. 

(a) The “Deemed Transactions” shall consist of a portfolio of hypothetical over-the-counter fixed-for-floating swap
transactions under which the Borrower (and its Restricted Subsidiaries) are, on a net volume basis, the “floating price” payor (or has an equivalent position) and which have the net volumes and fixed prices and relate to the delivery
periods in Columns I, II, III and IV of Schedule 1.1(e). 
 (b) The volumes subject to the Deemed Transactions may, from
time to time, be subject to adjustment as follows: 
 (i) with respect to the monthly volumes referenced in
Column III of Schedule 1.1(e) hereto, the Borrower may: 
 (A) without any additional fee,
(x) increase the volumes in earlier periods if it simultaneously and permanently decreases by the same amount the volumes in later periods or (y) decrease the volume in any period without increasing the volume in any other period, and

  

#4812-2844-92899582-0297 
 -232- 

 (B) decrease volumes in earlier periods and simultaneously and permanently
increases by the same amount the volumes in the later periods; provided that, prior to the effectiveness of any such simultaneous decrease in earlier volumes and increases in later volumes, the Borrower shall have paid to the Posting Lead
Arranger and Bookrunner the Ad Hoc Adjustment Maintenance Fee (as defined in the Posting Facility Fee Letter) in respect of such change; and 
 (ii) with respect to the monthly volumes referenced in Column II of Schedule 1.1(e), the Borrower may reduce such volumes on a pro rata basis across all periods, so long as the Borrower pays to the
Posting Lead Arranger and Bookrunner, the Partial Termination Maintenance Fee (as defined in the Posting Facility Fee Letter) for the volumes so reduced accrued through the date of such reduction; provided that, the Borrower may make no more
than six volume adjustments in any consecutive 12 month period and no more than one volume adjustment during any period of 30 consecutive days. 
 14.8. Evidence of Indebtedness. 
 (a) Each Posting Lender shall maintain in
accordance with its usual practice an account or accounts evidencing the Indebtedness to such Lender resulting from each Posting Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such
Lender from time to time under this Agreement. 
 (b) The Posting Agent shall maintain accounts in which it will record
(i) the amount and date of each Posting Advance made hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Posting Lender hereunder and (iii) the amount of any
sum received by the Posting Agent hereunder from the Borrower and each Lender’s share thereof. 
 (c) The entries made in
the accounts maintained pursuant to clauses (a) and (b) above shall, to the extent permitted by Applicable Law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided,
however, that the failure of any Lender or the Posting Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Posting Advances Outstanding in accordance with their
terms. 
 14.9. Termination and Reduction of Posting Commitments. 

(a) The Posting Commitments shall terminate automatically at 5:00 p.m. (New York time) on the Posting Facility Maturity Date. 

(b) Subject to clause (c) below, upon at least ten Business Days’ prior irrevocable written notice to the Posting Agent,
the Borrower may at the end of any calendar month, in whole permanently terminate the Posting Commitments. The Posting Agent shall advise the Posting Lenders of any notice given pursuant to this clause (b). 

(c) If the Posting Commitments terminate in whole prior to December 31, 2012 for any reason other than as a result of a Lender
Default, the Borrower shall pay to the Posting Lead Arranger and Bookrunner, the Final Termination Maintenance Fee (as defined in the Posting Facility Fee Letter). 

  

#4812-2844-92899582-0297 
 -233- 

 (d) The Borrower shall pay to the Facility Lead Arranger and Bookrunner on the date of the
termination of the Posting Commitments, any Maintenance Fees accrued through the date of such termination. 
 14.10. Pro Rata
Treatment. Each Posting Advance shall be allocated pro rata among the Lenders in accordance with their respective Posting Commitments (or, if such Posting Commitments shall have expired or been terminated, in accordance with the respective
principal amounts of their Posting Advances Outstanding). Each repayment of any Posting Advance and each payment of interest on the Posting Advances shall be allocated pro rata among the Lenders in accordance with their respective Posting
Commitments (or, if such Posting Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their Posting Advances Outstanding). Each Lender agrees that in computing such Lender’s portion of any
Posting Advance to be made hereunder, the Posting Agent may, in its discretion, round each Lender’s percentage of such Posting Advance to the next higher or lower whole dollar amount. 

14.11. Trading Acknowledgment. The Borrower hereby acknowledges that, with respect to Goldman Sachs Credit Partners L.P.,
(i) one or more of its affiliates (“Trading Affiliates”) are merchants of crude oil, petroleum products, natural gas, electricity and other commodities and may, from time to time, be dealing with prospective counterparties, or
pursuing trading or hedging strategies, in connection with aspects of such Trading Affiliates’ business that are unrelated to the Posting Facility and that such dealings and such trading or hedging strategies may be different from or opposite
to those being pursued by, for, or in connection with, the Posting Facility or by or for any Credit Party or such Person’s account, (ii) nothing herein or in the Credit Documents shall be construed to prevent any such Trading Affiliate, or
any of its partners, officers, employees or affiliates, in any way from purchasing, selling or otherwise trading in crude oil, petroleum products, natural gas or any other commodity for its or their own account or for the account of others, whether
prior to, simultaneously with or subsequent to the term of the Posting Facility and (iii) such trading and hedging activities may be in conflict with or have an adverse effect on the trading or hedging activities of a Credit Party or
transactions to which any Credit Party is a party (including transactions that may be referenced in the Posting Facility).

(collectively with its successors and assigns as holder of this Note, the “Payee”), an amount equal to the principal amount agreed upon by Maker and Payee from time to time (such amount not to exceed TWO BILLION DOLLARS
($2,000,000,000) outstanding at any one time) and set forth (as of the most recent date) on Schedule I attached hereto, together with interest thereon at the interest rate herein described, and otherwise in strict accordance with the terms and
provisions hereof. 
 1. Payments. All payments under this Note shall be made in immediately available
funds in lawful money of the United States of America which at the time shall be legal tender for the payment of all debts, public and private. 
 2. Interest. Interest shall accrue on the unpaid daily principal balance hereof on a monthly basis (i.e. from, and including, the first day of such month to, and including, the last day of such
month) at a rate equal to one-month LIBOR (as reasonably determined by Maker on the first business day of each month) plus five hundred (500) basis points. Interest shall be calculated on the basis of a three hundred sixty (360) day year
for the actual days elapsed. Unless otherwise agreed to by Maker and Payee, interest shall be paid on the last calendar day of each month; provided, however, if such day is not a business day, then such interest shall be paid, without penalty, on
the first business day of the next succeeding month. 
 3. Interest Computation. At no time shall the
interest rate on indebtedness evidenced by this Note exceed the maximum lawful rate of interest which may be contracted for, charged, taken, reserved or received by Payee in accordance with the applicable laws of the State of Texas (or applicable
United States federal law to the extent that such law permits the Payee to contract for, charge, take, reserve or receive a greater amount than under Texas law), taking into account all charges made in connection with the transactions evidenced by
this Note (“Maximum Lawful Rate”). 
 4. Optional Prepayment. Maker may prepay at any
time in whole, or from time to time in part, at its option, amounts due under this Note without premium or penalty.

several lenders named therein and Citibank N.A., as Administrative Agent. 
 6. Default Interest Rate. If
the unpaid principal balance of any advance made hereunder is not paid on demand, such matured unpaid principal balance shall thereafter bear interest at the Maximum Lawful Rate. After maturity, interest shall be computed on the basis of a three
hundred sixty-five (365) day year. 
 7. Waivers. MAKER AND ANY ENDORSERS OR GUARANTORS SEVERALLY
WAIVE AND RELINQUISH PRESENTMENT FOR PAYMENT, NOTE OF NONPAYMENT OR NONPERFORMANCE, PROTEST, NOTICE OF PROTEST, NOTICE OF INTENT TO ACCELERATE, NOTICE OF ACCELERATION OR ANY OTHER NOTICES OR ANY OTHER ACTION. 

8. Guarantors. Each of Energy Future Competitive Holdings Company and Energy Future Intermediate Holding Company
LLC (each, a “Guarantor,” and together, the “Guarantors”) hereby, jointly and severally, fully and unconditionally guarantees all payment obligations of Maker hereunder. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Maker, any right to require a proceeding
first against the Maker, protest, notice and all demands whatsoever and covenants that its guarantee shall not be discharged except by complete performance of the obligations contained hereunder. If Payee is required by any court or otherwise to
return to the Maker, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Maker or the Guarantors, any amount paid to the Payee, each Guarantor agrees that its guarantee, to the extent
theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Payee in respect of any obligations guaranteed hereby until payment in full of
all obligations guaranteed hereby. Each payment to be made by a Guarantor in respect of its guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 

9. Special Covenant. Maker hereby covenants and agrees that the sum of (without duplication) (A) the
aggregate amount of outstanding senior secured indebtedness (including guarantees) of Maker and any subsidiary of Maker, including Energy Future Intermediate Holdings Company LLC (“EFIH”), that is secured on a second priority basis
by the equity interests that EFIH owns in Oncor Electric Delivery Holdings Company LLC or any successor thereto (such indebtedness, “EFIH Second Priority Debt”) plus (B) the aggregate amount of outstanding Parent Loans (as such
term is defined in the Credit Agreement), shall not exceed, at any time, the maximum amount of EFIH Second Priority Debt permitted by the EFH 10% Indenture (as defined in the Credit Agreement), as such indenture is in effect on the Amendment
No. 2 Effective Date (as defined in the Credit Agreement). 
 10. Set-off. At any time, in addition
to any rights and remedies of the Payee provided by the applicable laws of the State of Texas, Payee shall have the right, upon prior notice to Maker, upon any amount becoming due and payable by Maker hereunder to set-off and

  
 Schedule
1.1(h) to the Credit Agreement 

 
appropriate and apply against such amount any and all loans or similar extensions of credit made by Maker to Payee, in each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by Payee to or for the credit or the account of Maker. 
 11. Usury
Savings. It is expressly stipulated and agreed to be the intent of Maker and Payee at all times to comply strictly with the applicable Texas law governing the maximum rate or amount of interest payable on the indebtedness evidenced by this Note
(or applicable United States federal law to the extent that such law permits the Payee to contract for, charge, take, reserve or receive a greater amount than under Texas law). If any amount (i) contracted for, charged, taken, reserved or
received pursuant to this Note, or any other communication or writing between Maker and Payee, (ii) contracted for, charged or taken, reserved or received by reason of Payee’s demand of payment, or (iii) Maker will have paid or Payee

Lawful Rate shall be automatically cancelled, ab initio, and all amounts in excess of the Maximum Lawful Rate theretofore collected by Payee shall be credited on the principal balance of this Note owed by Maker (or if such amounts have been paid in
full, refunded to Maker).

accordance with the laws of the State of Texas.

Priorities and Agreements with Respect to Shared Collateral 

SECTION 2.01. Subordination of Liens. Notwithstanding the date, time, method, manner or order of filing or recordation of any
document or instrument or grant, attachment or perfection of any Liens granted to any Second Priority Representative or any Second Priority Secured Parties on the Shared Collateral or of any Liens granted to the Senior Collateral Agent or the Senior
Secured Lenders on the Shared Collateral (or any actual or alleged defect or deficiency in any of the foregoing) and notwithstanding any provision of the UCC, any Bankruptcy Law, any other applicable law, any Second Priority Debt Document or any
Senior Debt Document, whether the Senior Collateral Agent, either directly or through agents, holds possession of, or has control over, all or any part of the Shared Collateral, the fact that any such Liens may be subordinated, voided, avoided,
invalidated or lapsed or any other circumstance whatsoever, each Second Priority Representative, on behalf of itself and each Second Priority Secured Party under its Second Priority Debt Facility, hereby agrees that (i) any Lien on the Shared
Collateral securing any Senior Obligations now or hereafter held by or on behalf of the Senior Collateral Agent, any Senior Secured Parties or any Senior Representative or other agent or trustee therefor, regardless of how acquired, whether by
grant, statute, operation of law, subrogation or otherwise, shall have priority over and be senior in all respects and prior to any Lien on the Shared Collateral securing any Second Priority Debt Obligations and (ii) any Lien on the Shared
Collateral securing any Second Priority Debt Obligations now or hereafter held by or on behalf of any Second Priority Representative, any Second Priority Secured Parties or any Second Priority Representative or other agent or trustee therefor,
regardless of how acquired, whether by grant, statute, operation of law, subrogation or otherwise, shall be junior and subordinate in all respects to all Liens on the Shared Collateral securing any Senior Obligations. All Liens on the Shared
Collateral securing any Senior Obligations shall be and remain senior in all respects and prior to all Liens on the Shared Collateral securing any Second Priority Debt Obligations for all purposes, whether or not such Liens securing any Senior
Obligations are (x) subordinated to any Lien securing any other obligation of the Company, any other Grantor or any other Person or (y) otherwise subordinated, voided, avoided, invalidated or lapsed. Notwithstanding any failure by any
Senior Secured Party or Second Priority Secured Party to perfect its security interests in the Shared Collateral or any avoidance, invalidation or subordination by any third party or court of competent jurisdiction of the security interests in the
Shared Collateral granted to the Senior Secured Parties or the Second Priority Secured Parties, the priority and rights as between the Senior Secured Parties and the Second Priority Secured Parties with respect to the Shared Collateral shall be as
set forth herein. 
 SECTION 2.02. Nature of Senior Lender Claims. Each Second Priority Representative, on behalf of
itself and each Second Priority Secured Party under its Second Priority Debt Facility, acknowledges that (a) a portion of the Senior Obligations is revolving in nature and that the amount thereof that may be outstanding at any time or from time
to time may be increased or reduced and subsequently reborrowed, (b) the terms of the Senior Debt Documents and the Senior Obligations may be amended, supplemented or otherwise modified, and the Senior Obligations, or a portion thereof, may be
Refinanced from time to time and (c) the aggregate amount of the Senior Obligations may be increased, in each case, without notice to or consent by the Second Priority Representatives or the Second Priority Secured Parties and without affecting
the provisions hereof. The Lien priorities provided for in Section 2.01 shall not be altered or otherwise affected by any amendment, supplement or other modification, or any Refinancing, of either the Senior Obligations or the Second Priority
Debt Obligations, or any portion 
  
 Exhibit R to the Credit Agreement 

  
 - 9 -

 
thereof. As between the Company and the other Grantors and the Second Priority Secured Parties, the foregoing provisions will not limit or otherwise affect the obligations of the Company and the
other Grantors contained in any Second Priority Debt Document with respect to the incurrence of additional Senior Obligations. 

SECTION 2.03. Prohibition on Contesting Liens. Each of the Second Priority Representatives, for itself and on behalf of each
Second Priority Secured Party under its Second Priority Debt Facility, agrees that it shall not (and hereby waives any right to) take any action to challenge, contest or support any other Person in contesting or challenging, directly or indirectly,
in any proceeding (including any Insolvency or Liquidation Proceeding), the validity, extent, perfection, priority or enforceability of any Lien securing any Senior Obligations held (or purported to be held) by or on behalf of the Senior Collateral
Agent or any of the Senior Secured Parties or any Senior Representative or other agent or trustee therefor in any Senior Collateral, and the Senior Collateral Agent and each Senior Representative, for itself and on behalf of each Senior Secured
Party under its Senior Facility, agrees that it shall not (and hereby waives any right to) contest or support any other Person in contesting, in any proceeding (including any Insolvency or Liquidation Proceeding), the validity, extent, perfection,
priority or enforceability of any Lien securing any Second Priority Debt Obligations held (or purported to be held) by or on behalf of any Second Priority Representative or any of the Second Priority Secured Parties in the Second Priority
Collateral; provided that nothing in this Agreement shall be construed to prevent or impair the rights of the Senior Collateral Agent or any Senior Representative to enforce this Agreement (including the priority of the Liens securing the
Senior Obligations as provided in Section 2.01) or any of the Senior Debt Documents. 
 SECTION 2.04. No New Liens.
The parties hereto agree that, so long as the Discharge of Senior Obligations has not occurred, (a) none of the Grantors shall grant or permit any additional Liens on any asset or property of any Grantor to secure any Second Priority Debt
Obligation unless it has granted, or concurrently therewith grants, a Lien on such asset or property of such Grantor to secure the Senior Obligations; and (b) each Second Priority Representative agrees, for itself and on behalf of each
applicable Second Priority Secured Party, whether or not any Insolvency or Liquidation Proceeding has been commenced by or against the Company or any other Grantor, that it shall not acquire or hold any Lien on any assets of the Company or any other
Grantor securing any Second Priority Debt Obligations that are not also subject to the first-priority Lien in respect of the Senior Obligations under the Senior Debt Documents (other than with respect to Additional Senior Debt Obligations that, by
their terms, are not intended to be secured by all of the Senior Collateral and, in particular, are not intended to be secured by such assets). If any Second Priority Representative or any Second Priority Secured Party shall (nonetheless and in
breach hereof) acquire or hold any Lien on any Collateral that is not also subject to the first-priority Lien in respect of the Senior Obligations under the Senior Debt Documents, then such Second Priority Representative shall, without the need for
any further consent of any party and notwithstanding anything to the contrary in any other document, be deemed to also hold and have held such Lien for the benefit of the Senior Collateral Agent as security for the applicable Senior Obligations
(subject to the lien priority and other terms hereof) and shall promptly notify the Senior Collateral Agent in writing of the existence of such Lien and in any event take such actions as may be requested by the Senior Collateral Agent to assign or
release such Liens to the Senior Collateral Agent (and/or its designees) as security for the applicable Senior Obligations (but may retain a junior lien on such assets or property subject to the terms hereof) and until such release or assignment,
shall be deemed to hold and have held such Lien for the benefit of the Senior Collateral Agent as security for the Senior Obligations. To the extent that the foregoing provisions are not complied with for any reason, without limiting any other
rights and remedies available to the Senior Secured Parties, the Second Priority Representatives and the other Second Priority Secured Parties agree that any amounts received by or distributed to any of them pursuant to or as a result of Liens
granted in contravention of this Section 2.04 shall be subject to Section 4.02. 
  
 Exhibit R to the Credit Agreement 

  
 - 10 -

 Notwithstanding anything to the contrary set forth in this Agreement (including this Section 2.04), the
Grantors may grant or permit Liens solely on the cash proceeds (and any deposit account in which such proceeds are deposited) of any issuance or incurrence of any Second Priority Debt Obligations for the benefit of the holders of such obligations
(including any representative or trustee thereof) without granting a Lien on such assets to secure the Senior Obligations or any Second Priority Debt Obligations other than the Second Priority Debt Obligations the issuance of which created such cash
proceeds. 
 SECTION 2.05. Perfection of Liens. Except for the agreements of the Senior Collateral Agent pursuant to
Section 5.07, none of the Senior Collateral Agent, the Senior Representatives or the Senior Secured Parties shall be responsible for perfecting and maintaining the perfection of Liens with respect to the Shared Collateral for the benefit of the
Second Priority Representatives or the Second Priority Secured Parties. The provisions of this Agreement are intended solely to govern the respective Lien priorities as between the Senior Secured Parties and the Second Priority Secured Parties and
such provisions shall not impose on the Senior Collateral Agent, the Senior Representatives, the Senior Secured Parties, the Second Priority Representatives, the Second Priority Secured Parties or any agent or trustee therefor any obligations in
respect of the disposition of Proceeds of any Shared Collateral which would conflict with prior perfected claims therein in favor of any other Person or any order or decree of any court or governmental authority or any applicable law. 

SECTION 2.06. Waiver of Marshalling. Until the Discharge of the Senior Obligations, each Second Priority Representative, on behalf
of itself and the applicable Second Priority Secured Parties, agrees not to assert and hereby waives, to the fullest extent permitted by law, any right to demand, request, plead or otherwise assert or otherwise claim the benefit of, any marshalling,
appraisal, valuation or other similar right that may otherwise be available under applicable law with respect to the Shared Collateral or any other similar rights a junior secured creditor may have under applicable law. 

ARTICLE III 

Enforcement 
 SECTION 3.01. Exclusive Enforcement. Until the Discharge of Senior Obligations has occurred, whether or not an Insolvency or Liquidation Proceeding has been commenced by or against any Grantor, the
Senior Secured Parties shall have the exclusive right to take and continue any Enforcement Action with respect to the Shared Collateral, without any consultation with or consent of any Second Priority Secured Party, but subject to the provisos set
forth in Sections 3.02 and 6.01. Upon the occurrence and during the continuance of a default or an event of default under the Senior Debt Documents, the Senior Collateral Agent and the other Senior Secured Parties may take and continue any
Enforcement Action with respect to the Senior Obligations and the Shared Collateral in such order and manner as they may determine in their sole discretion. 
 SECTION 3.02. Standstill and Waivers. The Second Priority Representative, on behalf of itself and the other Second Priority Secured Parties, agrees that, until the Discharge of the Senior
Obligations has occurred, subject to the proviso set forth in Section 6.01: 
 (a) they will not take or
cause to be taken any Enforcement Action with respect to the Shared Collateral; 
 (b) they will not take or
cause to be taken any action, the purpose or effect of which is to make any Lien in respect of any Second Priority Debt Obligation pari passu with or senior to, or to give any Second Priority Secured Party any preference or priority relative to, the
Liens with respect to the Senior Obligations or the Senior Secured Parties with respect to any of the Shared Collateral; 
  

Exhibit R to the Credit Agreement 

  
 - 11 -

 (c) they will not contest, oppose, object to, interfere with, hinder or
delay, in any manner, whether by judicial proceedings (including without limitation the filing (including on the basis of a deficiency claim, unsecured claim or otherwise) of an Insolvency or Liquidation Proceeding) or otherwise, any foreclosure,
sale, lease, exchange, transfer or other disposition of the Shared Collateral by any Senior Secured Party or any other Enforcement Action taken with respect to the Shared Collateral (or any forbearance from taking any Enforcement Action with respect
to the Shared Collateral) by or on behalf of any Senior Secured Party; 
 (d) they have no right to
(i) direct either the Senior Collateral Agent or any other Senior Secured Party to exercise any right, remedy or power with respect to the Shared Collateral or pursuant to the Senior Collateral Documents or (ii) consent or object to the
exercise by the Senior Collateral Agent or any other Senior Secured Party of any right, remedy or power with respect to the Shared Collateral or pursuant to the Senior Collateral Documents or to the timing or manner in which any such right is
exercised or not exercised (or, to the extent they may have any such right described in this clause (d), whether as a junior lien creditor or otherwise, they hereby irrevocably waive such right); 

(e) they will not institute any suit or other proceeding or assert in any suit, Insolvency or Liquidation Proceeding or
other proceeding any claim against any Senior Secured Party seeking damages from or other relief by way of specific performance, injunction or otherwise, with respect to, and no Senior Secured Party shall be liable for, any action taken or omitted
to be taken by any Senior Secured Party with respect to the Shared Collateral or pursuant to the Senior Debt Documents; and 
 (f) they will not seek, and hereby waive any right, to have the Shared Collateral or any part thereof marshaled upon any foreclosure or other disposition of the Shared Collateral; 

(g) they will not make any judicial or nonjudicial claim or demand or commence any judicial or non-judicial proceedings
against any Grantor or any of their respective subsidiaries or affiliates under or with respect to any Second Priority Collateral Document seeking payment or damages from or other relief by way of specific performance, instructions or otherwise
under or with respect to any Second Priority Collateral Document (other than filing a proof of claim) or exercise any right, remedy or power under or with respect to, or otherwise take any action to enforce, other than filing a proof of claim, any
Second Priority Collateral Document; or 
 (h) they will not commence judicial or nonjudicial foreclosure
proceedings with respect to, seek to have a trustee, receiver, liquidator or similar official appointed for or over, attempt any action to take possession of any Shared Collateral, exercise any right, remedy or power with respect to, or otherwise
take any action to enforce their interest in or realize upon, the Shared Collateral or pursuant to the Second Priority Collateral Documents; 

provided that, notwithstanding the foregoing, any Second Priority Secured Party may exercise its rights and remedies in respect of the Shared
Collateral under the Second Priority Collateral Documents or applicable law after the passage of a period of 180 days (the “Standstill Period”) from the date of delivery of a notice in writing to the Senior Collateral Agent of its
intention to exercise such rights and remedies, which notice may only be delivered following the occurrence of and during the continuation of an “Event of Default” under and as defined in the Second Priority Debt Documents (which notice
shall specify such Event of Default); provided, further, however, that, notwithstanding the foregoing, in no event shall any 
  
 Exhibit R to the Credit Agreement 

  
 - 12 -

 
Second Priority Secured Party exercise or continue to exercise any such rights or remedies if, notwithstanding the expiration of the Standstill Period, (i) any Senior Secured Party shall
have commenced and is diligently pursuing the exercise of any of its rights and remedies with respect to any of the Shared Collateral or (ii) an Insolvency or Liquidation Proceeding in respect of any Grantor shall have been commenced; and
provided, further, that in any Insolvency or Liquidation Proceeding commenced by or against any Grantor, the Second Priority Representative and the Second Priority Secured Parties may take any action expressly permitted by
Section 6.01. Without limiting the generality of the foregoing, unless and until the Discharge of Senior Obligations has occurred, except as expressly provided in Section 6.01, the sole right of the Second Priority Representatives and the
Second Priority Secured Parties with respect to the Shared Collateral or any other Collateral is to hold a Lien on the Shared Collateral or such other Collateral in respect of the applicable Second Priority Debt Obligations pursuant to the Second
Priority Debt Documents, as applicable, for the period and to the extent granted therein and to receive a share of the proceeds thereof, if any, after the Discharge of Senior Obligations has occurred. For the avoidance of doubt, nothing in this
Agreement prohibits the acceleration of the Second Priority Obligations in accordance with the terms of the Second Priority Debt Documents. 
 SECTION 3.03. Judgment Creditors. In the event that any Second Priority Secured Party becomes a judgment lien creditor in respect of Shared Collateral as a result of its enforcement of its rights
as an unsecured creditor, any such judgment lien shall be subject to the terms of this Agreement for all purposes (including in relation to the Senior Lien and the Senior Obligations) to the same extent as other Liens securing the Second Priority
Debt Obligations are subject to the terms of this Agreement. 
 SECTION 3.04. Cooperation. Each Second Priority
Representative, on behalf of itself and the other Second Priority Secured Parties under the Second Priority Debt Facility to which it is a party, agrees that each of them shall take such actions as the Senior Collateral Agent shall request in
connection with the exercise by the Senior Secured Parties of their rights set forth herein. Each Second Priority Representative hereby acknowledges and agrees that no covenant, agreement or restriction contained in any applicable Second Priority
Debt Document shall be deemed to restrict in any way the rights and remedies of the Senior Collateral Agent or Senior Secured Parties with respect to the Senior Collateral as set forth in this Agreement and the Senior Debt Documents. 

SECTION 3.05. No Additional Rights For the Grantors Hereunder. Except as provided in Section 3.06, if any Senior Secured
Party or Second Priority Secured Party shall enforce its rights or remedies in violation of the terms of this Agreement, no Grantor shall be entitled to use such violation as a defense to any action by any Senior Secured Party or Second Priority
Secured Party, nor to assert such violation as a counterclaim or basis for set off or recoupment against any Senior Secured Party or Second Priority Secured Party. 
 SECTION 3.06. Actions upon Breach. (a) If any Second Priority Secured Party, contrary to this Agreement, commences, participates or supports any Person commencing or participating in any
action or proceeding against or with respect to any Grantor or the Shared Collateral, such Grantor, with the prior written consent of the Senior Collateral Agent, may interpose as a defense or dilatory plea the making of this Agreement, and any
Senior Secured Party may intervene and interpose such defense or plea in its or their name or in the name of such Grantor. 

(b) Should any Second Priority Representative or any Second Priority Secured Party, contrary to this Agreement, in any way take, attempt
to take or threaten to take any action with respect to the Shared Collateral (including any attempt to realize upon or enforce any remedy with respect to this Agreement) or fail to take any action required by this Agreement, the Senior Collateral
Agent or any Senior Representative or other Senior Secured Party (in its or their own name or in the name of the Company or any other Grantor) or the Company or any other Grantor may obtain relief against such

  

Exhibit R to the Credit Agreement 

  
 - 13 -

 
Second Priority Representative or such Second Priority Secured Party by injunction, specific performance and/or other appropriate equitable relief. Each Second Priority Representative, on behalf
of itself and each Second Priority Secured Party under its Second Priority Facility, hereby (i) agrees that the Senior Secured Parties’ damages from the actions of the Second Party Representatives or any Second Priority Secured Party may
at that time be difficult to ascertain and may be irreparable and waives any defense that the Company, any other Grantor or the Senior Secured Parties cannot demonstrate damage or be made whole by the awarding of damages and (ii) irrevocably
waives any defense based on the adequacy of a remedy at law and any other defense that might be asserted to bar the remedy of specific performance in any action that may be brought by the Senior Collateral Agent, any Senior Representative or and
Senior Secured Party. 
 SECTION 3.07. Option to Purchase. (a) The Senior Collateral Agent agrees that it will give
the Second Priority Representative written notice (the “Enforcement Notice”) within ten days after (i) the occurrence of any Event of Default under any Senior Debt Document and the commencement of any Enforcement Action with
respect to Shared Collateral (which notice shall be effective for all Enforcement Actions taken after the date of such notice so long as the Senior Collateral Agent is diligently pursuing in good faith the exercise of its default or enforcement
rights or remedies against, or diligently attempting in good faith to vacate any stay of enforcement rights of its Senior Liens on a material portion of the Shared Collateral, including, without limitation, all Enforcement Actions identified in such
notice), (ii) acceleration of the Senior Obligations in accordance with the terms of the Senior Debt Documents; or (iii) the commencement of an Insolvency or Liquidation Proceeding . Any Second Priority Secured Party shall have the option
upon receipt of the Enforcement Notice by the Second Priority Representative, by irrevocable written notice (the “Purchase Notice”) delivered by the Second Priority Representative to the Senior Collateral Agent no later than ten
days after delivery from the Senior Collateral Agent of the Enforcement Notice, to purchase all (but not less than all) of the Senior Obligations from the Senior Secured Parties. If the Second Priority Representative so delivers the Purchase Notice,
the Senior Collateral Agent shall terminate any existing Enforcement Actions and shall not take any further Enforcement Actions; provided that (i) the Purchase shall have been consummated on the date specified in the Purchase Notice in
accordance with this Section 3.07 and (ii) prior to such date the Senior Collateral Agent may continue to take such Enforcement Action deemed by it to be necessary to the preservation of the rights of the Senior Secured Parties or their
rights in the Shared Collateral. 
 (b) On the date specified by the Second Priority Representative in the Purchase Notice
(which shall be a Business Day not less than five days, nor more than ten days, after receipt by the Senior Collateral Agent of the Purchase Notice), the Senior Secured Parties shall, subject to any required approval of any court or other
governmental authority then in effect, sell to the Second Priority Secured Parties electing to purchase pursuant to Section 3.07(a) (the “Purchasing Parties”), and the Purchasing Parties shall purchase (the
“Purchase”) from the Senior Secured Parties, the Senior Obligations; provided that the Senior Obligations purchased shall not include any rights of Senior Secured Parties with respect to indemnification and other
obligations of the Grantors under the Senior Debt Documents that are expressly stated to survive the termination of the Senior Debt Documents (the “Surviving Obligations”). 

(c) Without limiting the obligations of the Grantors under the Senior Debt Documents to the Senior Secured Parties with respect to the
Surviving Obligations (which shall not be transferred in connection with the Purchase), on the date of the Purchase, the Purchasing Parties shall (i) pay in cash to the Senior Secured Parties as the purchase price (the “Purchase
Price”) therefor the full amount of all Senior Obligations then outstanding and unpaid (including principal, interest, fees, breakage costs, attorneys’ fees and expenses, and, in the case of any Secured Hedging Agreement, the amount
that would be payable by the relevant Grantors thereunder if it were to terminate such Secured Hedging Agreement on the date of the Purchase or, if not terminated, an amount determined by the relevant Senior Secured Party to be necessary to
collateralize its credit risk arising out of such Secured Hedging Agreement, (ii)
  

Exhibit R to the Credit Agreement 

  
 - 14 -

 
furnish cash collateral (the “LC Cash Collateral”) to the Senior Secured Parties in such amounts as the relevant Senior Secured Parties determine is reasonably necessary to
secure such Senior Secured Parties in connection with any outstanding Letters of Credit (not to exceed 105% of the aggregate undrawn face amount of such Letters of Credit), (iii) agree in writing in form and substance satisfactory to the Senior
Collateral Agent to reimburse the Senior Secured Parties for any loss, cost, damage or expense (including attorneys’ fees and expenses) in connection with any fees, costs or expenses related to any checks or other payments provisionally
credited to the Senior Obligations and/or as to which the Senior Secured Parties have not yet received final payment and (iv) agree in writing in form and substance satisfactory to the Senior Collateral Agent, after written request from the
Senior Collateral Agent, to reimburse the Senior Secured Parties in respect of indemnification obligations of the Grantors under the Senior Debt Documents as to matters or circumstances known to the Purchasing Parties at the time of the Purchase
which could reasonably be expected to result in any loss, cost, damage or expense to any of the Senior Secured Parties; provided that in no event shall any Purchasing Party have any liability for such amounts in excess of proceeds of Shared
Collateral received by the Purchasing Parties. 
 (d) The Purchase Price and LC Cash Collateral shall be remitted by wire
transfer in immediately available funds to such account of the Senior Collateral Agent as it shall designate to the Purchasing Parties. The Senior Collateral Agent shall, promptly following its receipt thereof, distribute the amounts received by it
in respect of the Purchase Price to the Senior Secured Parties in accordance with the Senior Debt Documents. Interest shall be calculated to but excluding the day on which the Purchase occurs if the amounts so paid by the Purchasing Parties to the
account designated by the Senior Collateral Agent are received in such account prior to 12:00 noon, New York City time, and interest shall be calculated to and including such day if the amounts so paid by the Purchasing Parties to the account
designated by the Senior Collateral Agent are received in such account later than 12:00 noon, New York City time. 
 (e) The
Purchase shall be made without representation or warranty of any kind by the Senior Secured Parties as to the Senior Obligations, the Shared Collateral or otherwise and without recourse to the Senior Secured Parties, except that the Senior Secured
Parties shall represent and warrant: (i) the amount of the Senior Obligations being purchased, (ii) that the Senior Secured Parties own the Senior Obligations free and clear of any liens or encumbrances and (iii) that the Senior
Secured Parties have the right to assign the Senior Obligations and the assignment is duly authorized. 
 (f) For the avoidance
of doubt, the parties hereto hereby acknowledge and agree that in no event shall the Second Priority Representative (i) be deemed to be a Purchasing Party for purposes of this Section 3.07, (ii) be subject to or liable for any
obligations of a Purchasing Party pursuant to this Section 3.07 or (iii) incur any liability to any Senior Secured Party or any other Person in connection with any Purchase pursuant to this Section 3.07. 

ARTICLE IV 

Payments 

SECTION 4.01. Application of Proceeds. All Shared Collateral and Proceeds thereof received in connection with the Disposition or
collection of the Shared Collateral in connection with an Enforcement Action, whether or not pursuant to an Insolvency or Liquidation Proceeding, shall be distributed as follows: first, to the payment on a pro rata basis of costs and expenses
of each Agent, as applicable, in connection with such Enforcement Action; second, to the Senior Collateral Agent for application to the Senior Obligations in accordance with the terms of the Senior Debt Documents, until the Discharge of
Senior Obligations has occurred; third, to Designated Second Priority Representative for application in accordance with the Second Priority Debt Documents; and fourth, the balance, if any, to the

  

Exhibit R to the Credit Agreement 

  
 - 15 -

 
Credit Parties or to whomsoever may be lawfully entitled to receive the same or as writ of competent jurisdiction may direct. Upon the Discharge of Senior Obligations, the Senior Collateral Agent
shall deliver promptly to the Designated Second Priority Representative any Shared Collateral or Proceeds thereof held by it in the same form as received, with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct,
to be applied by the relevant Second Priority Representative to the Second Priority Debt Obligations in such order as specified in the relevant Second Priority Debt Documents. 
 SECTION 4.02. Payments Over. So long as the Discharge of Senior Obligations has not occurred, any Shared Collateral or Proceeds thereof received by any Second Priority Representative or any Second
Priority Secured Party in contravention of this Agreement shall be segregated and held in trust for the benefit of and forthwith paid over to the Senior Collateral Agent for the benefit of the Senior Secured Parties in the same form as received,
with any necessary endorsements, or as a court of competent jurisdiction may otherwise direct, for application in accordance with Section 4.01, and each Second Priority Secured Party hereby authorizes the Senior Collateral Agent to make any
such endorsements as agent for each of the Second Priority Representatives or any such Second Priority Secured Party (which authorization, being coupled with an interest, is irrevocable). 

ARTICLE V 

Other Agreements 
 SECTION 5.01. Releases. (a) If, at any time any Grantor or any Senior Secured Party delivers notice to each Second Priority Representative with respect to any specified Shared Collateral
(including for such purpose, in the case of the sale or other disposition of all or substantially all of the equity interests in any Subsidiary, any Shared Collateral held by such Subsidiary or any direct or indirect Subsidiary thereof) that:

 (i) such specified Shared Collateral has been or is being sold, transferred or otherwise disposed of in
connection with a Disposition by the owner of such Shared Collateral in a transaction permitted under the Senior Debt Documents; or 
 (ii) the Senior Liens thereon have been or are being released in connection with a Subsidiary that is released from its guarantee under the Senior Debt Documents; or 

(iii) the Senior Liens thereon have been or are being otherwise released as permitted by the Senior Debt Documents or by
the Senior Collateral Agent on behalf of the Senior Secured Parties (unless, in the case of clause (ii) or (iii) of this Section 5.01(a) such release occurs in connection with, and after giving effect to, a Discharge of Senior
Obligations, which discharge is not in connection with a foreclosure of, or other exercise of remedies with respect to, Shared Collateral by the Senior Secured Parties (such discharge not in connection with any such foreclosure or exercise of
remedies or a sale or other disposition generating sufficient proceeds to cause the Discharge of Senior Obligations, a “Payment Discharge”)), 
 then the Second Priority Liens upon such Shared Collateral will automatically be released and discharged as and when, but only to the extent, such Liens on such Shared Collateral securing Senior
Obligations are released and discharged (provided that in the case of a Payment Discharge, the Liens on any Shared Collateral disposed of in connection with the satisfaction in whole or in part of Senior Obligations shall be automatically
released but any proceeds thereof not used for purposes of the Discharge of Senior Obligations or otherwise in accordance with the Second Priority Debt Documents shall be subject to Second Priority Liens and shall be applied pursuant to
Section 4.01). Upon delivery to the Second Priority Representatives of a notice from the Senior Collateral Agent stating that any such release of Liens 

 
 Exhibit R to the Credit Agreement 

  
 - 16 -

 
securing or supporting the Senior Obligations has become effective (or shall become effective upon the Second Priority Representatives’ release), the Second Priority Representatives will
promptly, at the Company’s expense, execute and deliver such instruments, releases, termination statements or other documents confirming such release on customary terms, which instruments, releases and termination statements shall be
substantially identical to the comparable instruments, releases and termination statements executed by the Senior Collateral Agent in connection with such release (and shall be prepared by the Senior Collateral Agent). In the case of the sale of
capital stock of a Subsidiary or any other transaction resulting in the release of such Subsidiary’s guarantee under the Senior Debt Documents in accordance with the Credit Agreement, the guarantee in favor of the Second Priority Secured
Parties, if any, made by such Subsidiary will automatically be released and discharged as and when, but only to the extent, the guarantee by such Subsidiary of Senior Obligations is released and discharged. 

(b) Each Second Priority Representative, for itself and on behalf of each Second Priority Secured Party under its Second Priority Debt
Facility, hereby irrevocably constitutes and appoints the Senior Collateral Agent and any officer or agent of the Senior Collateral Agent, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and
authority in the place and stead of such Second Priority Representative or such Second Priority Secured Party or in the Senior Collateral Agent’s own name, from time to time in the Senior Collateral Agent’s discretion, for the purpose of
carrying out the terms of this Section 5.01, to take any and all appropriate action and to execute any and all documents and instruments that may be necessary or desirable to accomplish the purposes of this Section 5.01, including any
termination statements, endorsements or other instruments of transfer or release (which appointment, being coupled with an interest, is irrevocable); provided that such appointment shall terminate automatically, without any action by the
Senior Collateral Agent or any Second Priority Secured Party, upon the Discharge of Senior Obligations, and provided, further, that the Senior Collateral Agent shall notify such Second Priority Representative or such Second Priority
Secured Party of any action taken by such Senior Collateral Agent as attorney-in-fact for such Second Priority Representative or such Second Priority Secured Party pursuant to this clause (b). 

(c) Unless and until the Discharge of Senior Obligations has occurred, each Second Priority Representative, for itself and on behalf of
each Second Priority Secured Party under its Second Priority Debt Facility, hereby consents to the application, whether prior to or after an Event of Default under any Senior Debt Document, of Deposit Account Collateral or proceeds of Shared
Collateral to the repayment of Senior Obligations pursuant to the Senior Debt Documents; provided that nothing in this Section 5.01(c) shall be construed to prevent or impair the rights of the Second Priority Representatives or the
Second Priority Secured Parties to receive proceeds in connection with the Second Priority Debt Obligations not otherwise in contravention of this Agreement. 
 (d) Notwithstanding anything to the contrary in any Second Priority Collateral Document, in the event the terms of a Senior Collateral Document and a Second Priority Collateral Document each require any
Grantor to (i) make payment in respect of any item of Shared Collateral to, (ii) deliver or afford control over any item of Shared Collateral to, or deposit any item of Shared Collateral with, (iii) register ownership of any item of
Shared Collateral in the name of or make an assignment of ownership of any Shared Collateral or the rights thereunder to, (iv) cause any securities intermediary, commodity intermediary or other Person acting in a similar capacity to agree to
comply, in respect of any item of Shared Collateral, with instructions or orders from, or to treat, in respect of any item of Shared Collateral, as the entitlement holder, (v) hold any item of Shared Collateral in trust for (to the extent such
item of Shared Collateral cannot be held in trust for multiple parties under applicable law), (vi) obtain the agreement of a bailee or other third party to hold any item of Shared Collateral for the benefit of or subject to the control of or,
in respect of any item of Shared Collateral, to follow the instructions of, or (vii) obtain the agreement of a landlord with respect to access to leased premises where any item of Shared Collateral is located or waivers or subordination of
rights with respect to any item of Shared Collateral in favor of, in

any case, both the Senior Collateral Agent and any Second Priority Representative or Second Priority Secured Party, such Grantor may, until the applicable Discharge of Senior Obligations has
occurred, comply with such requirement under the Second Priority Collateral Document as it relates to such Shared Collateral by taking any of the actions set forth above only with respect to, or in favor of, the Senior Collateral Agent. 

SECTION 5.02. Inspection; Insurance and Condemnation Awards. (a) Any Senior Secured Party and its representatives and
invitees may at any time inspect, repossess, remove and otherwise deal with the Shared Collateral, and the Senior Collateral Agent may advertise and conduct public auctions or private sales of the Shared Collateral, in each case without notice to,
the involvement of or interference by any Second Priority Secured Party or liability to any Second Priority Secured Party. 

(b) Unless and until the Discharge of Senior Obligations has occurred, the Senior Collateral Agent and the Senior Secured Parties shall
have the sole and exclusive right, subject to the rights of the Grantors under the Senior Debt Documents, (i) to be named as additional insured and loss payee under any insurance policies maintained from time to time by any Grantor (except that
to the extent provided for in the Second Priority Debt Documents, the Second Priority Debt Representatives shall have the right to be named as additional insureds and loss payees so long as their junior lien status is identified in a manner
satisfactory to the Senior Collateral Agent), (ii) to adjust settlement for any insurance policy covering the Shared Collateral in the event of any loss thereunder, and to make, adjust or settle any claim under any title insurance policy
covering any Shared Collateral (including any such policy issued in favor of the Second Priority Representative and/or any Second Priority Secured Party (and each Second Secured Debt Party hereby authorizes the Senior Collateral Agent to make,
adjust or settle any such claim with respect thereto as agent for each of the Second Priority Representatives or any such Second Priority Secured Party, which authorization, being coupled with an interest, is irrevocable) and (iii) to approve
any award granted in any condemnation or similar proceeding affecting the Shared Collateral. Unless and until the Discharge of Senior Obligations has occurred, all proceeds of any such policy and any such award, if in respect of the Shared
Collateral, shall be paid (A) first, prior to the occurrence of the Discharge of Senior Obligations, to the Senior Collateral Agent for the benefit of Senior Secured Parties pursuant to the terms of the Senior Debt Documents, (B) second,
after the occurrence of the Discharge of Senior Obligations, to the Designated Second Priority Representative for the benefit of the Second Priority Secured Parties pursuant to the terms of the applicable Second Priority Debt Documents and
(C) third, if no Second Priority Debt Obligations are outstanding, to the owner of the subject property, such other Person as may be entitled thereto or as a court of competent jurisdiction may otherwise direct. So long as the Discharge of
Senior Obligations has not occurred, if any Second Priority Representative or any Second Priority Secured Party shall, at any time, receive any proceeds of any such policy or any such award in contravention of this Agreement, it shall pay such
proceeds over to the Senior Collateral Agent in accordance with the terms of Section 4.02. 
 SECTION 5.03. Second
Priority Collateral Documents. (a) Each Second Priority Representative, for itself and on behalf of each Second Priority Secured Party under its Second Priority Debt Facility, agrees that, unless otherwise agreed by the Senior Collateral
Agent, each Second Priority Collateral Document under its Second Priority Debt Facility shall include the following language (or language to a similar effect reasonably approved by the Senior Collateral Agent): 

“Notwithstanding anything herein to the contrary, (i) the liens and security interests granted to the [Second Priority Representative]
pursuant to this Agreement are expressly subject and subordinate to the liens and security interests granted in favor of the Senior Secured Parties (as defined in the Intercreditor Agreement referred to below), including liens and security interests
granted to Citibank, N.A., as administrative agent, pursuant to or in connection with the Credit Agreement, dated as of October 10, 2007, as amended by Amendment No. 1 thereto, dated as of August 7, 2009 (as further amended, restated,

  

Exhibit R to the Credit Agreement 

  
 - 18 -

 
supplemented or otherwise modified from time to time), among U.S. Holdings, as parent guarantor, the Company, as borrower, the other guarantors party thereto, the several banks and other
financial institutions or entities from time to time parties thereto as lenders, Citibank, N.A., as administrative agent and collateral agent and the other agents and entities party thereto, [and to the liens and security interests granted to
Citibank, N.A., as collateral agent pursuant to [Addition Senior Debt Documents (as amended, supplemented or otherwise modified from time to time)]] and (ii) the exercise of any right or remedy by the [Second Priority Representative]
hereunder is subject to the limitations and provisions of the Second Lien Intercreditor Agreement dated as of October 6 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Intercreditor
Agreement”), among Citibank, N.A., as Senior Collateral Agent, the [Second Priority Representative], U.S. Holdings, as parent guarantor, the Company, as borrower, the other guarantors party thereto, and the other parties (if any)
party thereto. In the event of any conflict between the terms of the Intercreditor Agreement and the terms of this Agreement, the terms of the Intercreditor Agreement shall govern.” 
 In addition, the Second Priority Representatives, on behalf of the Second Priority Secured Parties, agree that each mortgage, if applicable, covering any Shared Collateral shall contain such other
language as the Senior Collateral Agent may reasonably request to reflect the subordination of such mortgage to the Senior Liens in respect of such Shared Collateral. 
 (b) In the event the Senior Collateral Agent enters into any amendment, waiver or consent in respect of any of the Senior Collateral Documents for the purpose of adding to, or deleting from, or waiving or
consenting to any departures from any provisions of, any Senior Collateral Document or changing in any manner the rights of any parties thereunder, in each case solely with respect to any Shared Collateral, then such amendment, waiver or consent
shall apply automatically to any comparable provision of the Second Priority Collateral Document without the consent of or action by any Second Priority Secured Party; provided that notice of such amendment, waiver or consent shall be given
to the Second Priority Representative no later than 30 days after its effectiveness and, provided, further, that the failure to give such notice shall not affect the effectiveness and validity thereof. 

(c) Anything contained herein to the contrary notwithstanding, until the Discharge of Senior Obligations has occurred, no Second Priority
Collateral Document shall be entered into unless the Collateral covered thereby is also subject to a perfected first-priority interest in favor of the Senior Collateral Agent for the benefit of the Senior Secured Parties pursuant to the Senior
Collateral Documents (other than with respect to Additional Senior Obligations that, by their terms, are not intended to be secured by all of the Senior Collateral and, in particular, are not intended to be secured by such Collateral). 

SECTION 5.04. Amendments to Senior Debt Documents; Senior Obligations. Each Second Priority Representatives, on behalf of itself
and the Second Priority Secured Parties, agrees that, without affecting the obligations of the Second Priority Secured Parties hereunder, the Senior Collateral Agent, the Senior Representatives and the Senior Secured Parties represented thereby may,
at any time and from time to time, in their sole discretion without the consent of or notice to any such Second Priority Secured Party (except to the extent such notice or consent is required pursuant to the express provisions of this Agreement),
and without incurring any liability to such Second Priority Secured Party or impairing or releasing the subordination provided for herein, amend, restate, supplement, replace, refinance, extend, consolidate, restructure or otherwise modify any of
the Senior Debt Documents in any manner whatsoever, including to (i) change the manner, place, time or terms of payment, or renew, alter or increase, all or any of the Senior Obligations, or otherwise amend, restate, supplement or otherwise
modify in any manner, or grant any waiver or release with respect to, all or any part of the Senior Obligations or any of the Senior Debt Documents, (ii) retain or obtain a Lien on any Property of any Person to secure any of the Senior
Obligations, and in connection therewith to enter into any additional Senior Debt Documents, (iii) amend, or grant any waiver, compromise or release with respect to, or 

 
 Exhibit R to the Credit Agreement 

  
 - 19 -

 
consent to any departure from, any guaranty or other obligation of any Person obligated in any manner under or in respect of the Senior Obligations, (iv) release its Lien on any Shared
Collateral or other Property, (v) exercise or refrain from exercising any rights against any Credit Party or any other Person, (vi) retain or obtain the primary or secondary obligation of any other Person with respect to any of the Senior
Obligations, and (vii) otherwise manage and supervise the Senior Obligations as the applicable Senior Collateral Agent or Senior Representatives shall deem appropriate. 
 SECTION 5.05. Amendments to Second Priority Debt Documents. The Second Priority Representatives, on behalf of themselves and the Second Priority Secured Parties, agree that they shall not at any
time execute or deliver any amendment or other modification to any of the Second Priority Debt Documents inconsistent with or in violation of this Agreement. The Senior Collateral Agent, on behalf of itself and the Senior Secured Parties represented
thereby, agrees that, without affecting the obligations of the Senior Secured Parties hereunder, the Second Priority Representatives and the Second Priority Secured Parties may, at any time and from time to time, in their sole discretion without the
consent of or notice to any Senior Secured Party (except to the extent such notice or consent is required pursuant to the express provisions of this Agreement), and without incurring any liability to such Senior Secured Party or impairing or
releasing the priority provided for herein, amend, restate, supplement, replace, refinance, extend, consolidate, restructure or otherwise modify any of the Second Priority Documents in any manner whatsoever, including to (i) change the manner,
place, time or terms of payment, or renew, alter or increase, all or any of the Second Priority Debt Obligations, or otherwise amend, restate, supplement or otherwise modify in any manner, or grant any waiver or release with respect to, all or any
part of the Second Priority Debt Obligations or any of the Second Priority Debt Documents, (ii) retain or obtain a Lien on any Property of any Person to secure any of the Second Priority Debt Obligations, and in connection therewith to enter
into any additional Second Priority Debt Documents, (iii) amend, or grant any waiver, compromise or release with respect to, or consent to any departure from, any guaranty or other obligation of any Person obligated in any manner under or in
respect of the Second Priority Debt Obligations, (iv) release its Lien on any Shared Collateral or other Property, (v) exercise or refrain from exercising any rights against any Credit Party or any other Person, (vi) retain or obtain
the primary or secondary obligation of any other Person with respect to any of the Second Priority Debt Obligations, and (vii) otherwise manage and supervise the Second Priority Debt Obligations as the Second Lien Representatives shall deem
appropriate. 
 SECTION 5.06. 
 The Company agrees to promptly deliver to the Senior Collateral Agent copies of (i) any amendments, supplements or other modifications to the Second Priority Collateral Documents and (ii) any
new Second Priority Collateral Documents promptly after effectiveness thereof. 
 SECTION 5.07. Rights as Unsecured
Creditors. Notwithstanding anything to the contrary in this Agreement (except subject to Section 3.02 and Articles VI and VIII), the Second Priority Representatives and the Second Priority Secured Parties may exercise rights and remedies as
unsecured creditors against the Company and any other Grantor in accordance with the terms of the Second Priority Debt Documents and applicable law. Nothing in this Agreement shall prohibit the receipt by any Second Priority Representative or any
Second Priority Secured Party of the required payments of interest and principal so long as such receipt is not the direct or indirect result of (a) the exercise in contravention of this Agreement by any Second Priority Representative or any
Second Priority Secured Party of rights or remedies as a secured creditor in respect of Shared Collateral or other Collateral or (b) enforcement in contravention of this Agreement of any Lien in respect of Second Priority Debt Obligations held
by any of them. Nothing in this Agreement shall impair or otherwise adversely affect any rights or remedies the Senior Collateral Agent, the Senior Representatives or the Senior Secured Parties may have with respect to the Senior Collateral.

 SECTION 5.08. Gratuitous Bailee for Perfection. (a) The Senior Collateral Agent
acknowledges and agrees that if it shall at any time hold a Lien securing any Senior Obligations on any Shared Collateral that can be perfected by the possession or control of such Shared Collateral or of any account in which such Shared Collateral
is held, and if such Shared Collateral or any such account is in fact in the possession or under the control of the Senior Collateral Agent, or of agents or bailees of the Senior Collateral Agent (such Shared Collateral being referred to herein as
the “Pledged or Controlled Collateral”), or if it shall any time obtain any landlord waiver or bailee’s letter or any similar agreement or arrangement granting it rights or access to Shared Collateral, the Senior Collateral
Agent shall also hold such Pledged or Controlled Collateral, or take such actions with respect to such landlord waiver, bailee’s letter or similar agreement or arrangement, as sub-agent or gratuitous bailee for the relevant Second Priority
Representatives, in each case solely for the purpose of perfecting the Liens granted under the relevant Second Priority Collateral Documents and subject to the terms and conditions of this Section 5.07. 

(b) In the event that the Senior Collateral Agent (or its agents or bailees) has Lien filings against Intellectual Property that is part
of the Shared Collateral that are necessary for the perfection of Liens in such Shared Collateral, the Senior Collateral Agent agrees to hold such Liens as sub-agent and gratuitous bailee for the relevant Second Priority Representatives and any
assignee thereof, solely for the purpose of perfecting the security interest granted in such Liens pursuant to the relevant Second Priority Collateral Documents, subject to the terms and conditions of this Section 5.07 (such bailment being
intended, among other things, to satisfy the requirements of Sections 8-106(d)(3), 8-301(a)(2) and 9-313(c) of the UCC). 
 (c)
Except as otherwise specifically provided herein, until the Discharge of Senior Obligations has occurred, the Senior Collateral Agent shall be entitled to deal with the Pledged or Controlled Collateral in accordance with the terms of the Senior Debt
Documents as if the Liens under the Second Priority Collateral Documents did not exist. The rights of the Second Priority Representatives and the Second Priority Secured Parties with respect to the Pledged or Controlled Collateral shall at all times
be subject to the terms of this Agreement. 
 (d) The Senior Collateral Agent shall have no obligation whatsoever to the Second
Priority Representatives or any Second Priority Secured Party to assure that any of the Pledged or Controlled Collateral is genuine or owned by the Grantors or to protect or preserve rights or benefits of any Person or any rights pertaining to the
Shared Collateral, except as expressly set forth in this Section 5.07. The duties or responsibilities of the Senior Collateral Agent under this Section 5.07 shall be limited solely to holding or controlling the Shared Collateral and the
related Liens referred to in paragraphs (a) and (b) of this Section 5.07 as subagent and gratuitous bailee for the relevant Second Priority Representative for purposes of perfecting the Lien held by such Second Priority
Representative. 
 (e) The Senior Collateral Agent shall not have by reason of the Second Priority Collateral Documents or this
Agreement, or any other document, a fiduciary relationship in respect of any Second Priority Representative or any Second Priority Secured Party, and each Second Priority Representative, for itself and on behalf of each Second Priority Secured Party
under its Second Priority Debt Facility, hereby waives and releases the Senior Collateral Agent from all claims and liabilities arising pursuant to the Senior Collateral Agent’s role under this Section 5.07 as sub-agent and gratuitous
bailee with respect to the Shared Collateral. 
 (f) Upon the Discharge of Senior Obligations, the Senior Collateral Agent
shall, at the Grantors’ sole cost and expense, (i) (A) deliver to the Designated Second Priority Representative all Shared Collateral, including all proceeds thereof, held or controlled by the Senior Collateral Agent or any of its
agents or bailees, including the transfer of possession and control, as applicable, of the Pledged or 
  

Exhibit R to the Credit Agreement 

  
 - 21 -

 
Controlled Collateral, together with any necessary endorsements and notices to depositary banks, securities intermediaries and commodities intermediaries, and assign its rights under any landlord
waiver or bailee’s letter or any similar agreement or arrangement granting it rights or access to Shared Collateral (including pursuant to the delivery of change of agent notices under deposit account control agreements and similar agreements)
or (B) if the Second Priority Debt Obligations are not outstanding at such time, direct and deliver such Shared Collateral as a court of competent jurisdiction may otherwise direct, (ii) notify any applicable insurance carrier that it is
no longer entitled to be a loss payee or additional insured under the insurance policies of any Grantor issued by such insurance carrier and (iii) notify any governmental authority involved in any condemnation or similar proceeding involving
any Grantor that the Designated Second Party Representative is entitled to approve any awards granted in such proceeding. The Company and the other Grantors shall take such further action as is required to effectuate the transfer contemplated hereby
and shall indemnify the Senior Collateral Agent for loss or damage suffered by the Senior Collateral Agent as a result of such transfer, except to the extent such loss or damage is determined by a court of competent jurisdiction by a final and non
appealable judgment to have been suffered by the Senior Collateral Agent as a result of its own wilful misconduct, gross negligence or bad faith. The Senior Collateral Agent has no obligation to follow instructions from the Designated Second
Priority Representative in contravention of this Agreement. 
 (g) Neither the Senior Collateral Agent nor any of the Senior
Representatives or Senior Secured Parties shall be required to marshal any present or future collateral security for any obligations of the Company or any Subsidiary or other Grantor to the Senior Collateral Agent, any Senior Representative or any
Senior Secured Party under the Senior Debt Documents or any assurance of payment in respect thereof, or to resort to such collateral security or other assurances of payment in any particular order, and all of their rights in respect of such
collateral security or any assurance of payment in respect thereof shall be cumulative and in addition to all other rights, however existing or arising. 
 SECTION 5.09. When Discharge of Senior Obligations Deemed to Not Have Occurred. If, in connection with the Discharge of Senior Obligations, the Company or any other Grantor enters into any
substantially concurrent Refinancing of any Senior Obligations, then such Discharge of Senior Obligations shall automatically be deemed not to have occurred for all purposes of this Agreement and the applicable agreement governing such Senior
Obligations shall automatically be treated as a Senior Debt Document for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of Shared Collateral set forth herein and the granting by the Senior
Collateral Agent of amendments, waivers and consents hereunder and the agent, representative or trustee for the holders of such Senior Obligations shall be the Senior Collateral Agent for all purposes of this Agreement. Upon receipt of notice that
the Company has entered into a new Senior Debt Document (which notice shall include the identity of the new Senior Collateral Agent), each Second Priority Representative (including the Designated Second Priority Representative) shall promptly
(a) enter into such documents and agreements (at the expense of the Company), including amendments or supplements to this Agreement, as the Company or such new Senior Collateral Agent shall reasonably request in writing in order to provide the
new Senior Collateral Agent the rights of the Senior Collateral Agent contemplated hereby, in each case consistent in all material respects with this Agreement, (b) deliver to the Senior Collateral Agent all Shared Collateral, including all
proceeds thereof, held or controlled by such Second Priority Representative or any of its agents or bailees, including the transfer of possession and control, as applicable, of the Pledged or Controlled Collateral, together with any necessary
endorsements and notices to depositary banks, securities intermediaries and commodities intermediaries, and assign its rights under any landlord waiver or bailee’s letter or any similar agreement or arrangement granting it rights or access to
Shared Collateral, (c) notify any applicable insurance carrier that it is no longer entitled to be a loss payee or additional insured under the insurance policies of any Grantor issued by such insurance carrier and (d) notify any
governmental authority involved in any condemnation or similar proceeding involving a Grantor that the new Senior Collateral Agent is entitled to approve any awards granted in such proceeding.

 ARTICLE VI 
 Insolvency or Liquidation Proceedings. 
 SECTION 6.01. Filing of
Motions. Until the Discharge of Senior Obligations has occurred, the Second Priority Representative agrees on behalf of itself and the other Second Priority Secured Parties that no Second Priority Secured Party shall, in or in connection with
any Insolvency or Liquidation Proceeding, file any pleadings or motions, take any position at any hearing or proceeding of any nature, join with or support any other Person doing so, or otherwise take any action whatsoever, in each case that
(a) violates, or is prohibited by, this Article VI (or, in the absence of an Insolvency or Liquidation Proceeding, otherwise would violate or be prohibited by this Agreement), (b) asserts any right, benefit or privilege that arises in
favor of the Second Priority Representative or Second Priority Secured Parties, in whole or in part, as a result of their interest in the Shared Collateral (unless the assertion of such right is expressly permitted by this Agreement) or
(c) challenges the validity, priority, enforceability or voidability of any Liens or claims held by the Senior Collateral Agent or any other Senior Secured Party with respect to the Shared Collateral, or the extent to which the Senior
Obligations constitute secured claims or the value thereof under Section 506(a) of the Bankruptcy Code or otherwise; provided that the Second Priority Representative may (i) file a proof of claim in an Insolvency or Liquidation
Proceeding and (ii) file any necessary responsive or defensive pleadings in opposition of any motion or other pleadings made by any Person objecting to or otherwise seeking the disallowance of the claims of the Second Priority Secured Parties
on the Shared Collateral, subject to the limitations contained in this Agreement and only if consistent with the terms and the limitations on the Second Priority Representative imposed hereby. 

SECTION 6.02. Financing Issues. Until the Discharge of Senior Obligations has occurred, if the Company or any other Grantor shall
be subject to any Insolvency or Liquidation Proceeding, and if the Senior Collateral Agent or (with the prior written consent of the Senior Collateral Agent and the Majority Senior Parties) any Senior Representative, shall desire to consent (or not
object) to the sale, use or lease of cash collateral under the Bankruptcy Code or to provide financing to any Grantor under the Bankruptcy Code or to consent (or not object) to the provision of such financing to any Loan Party by any third party
(any such financing, “DIP Financing”), then each Second Priority Representative agrees, on behalf of itself and the other Second Priority Secured Parties, that each Second Priority Secured Party (a) will be deemed to have
consented to, will raise no objection to, nor support any other Person objecting to, and will not otherwise contest, the use of such cash collateral or to such DIP Financing, (b) will not request or accept adequate protection or any other
relief in connection with the use of such cash collateral or such DIP Financing except as set forth in Section 6.04 and (c) will subordinate (and will be deemed hereunder to have subordinated) the Second Priority Liens on any Shared
Collateral (i) to such DIP Financing on the same terms as the Senior Liens are subordinated thereto (and such subordination will not alter in any manner the terms of this Agreement), (ii) to any adequate protection provided to the Senior
Secured Parties or the Second Priority Secured Parties, (iii) to any “carve-out” for professional and United States Trustee fees agreed to by the Senior Collateral Agent or the other Senior Secured Parties, and (iv) agrees that
notice received two (2) calendar days prior to the entry of an order approving such usage of cash collateral or approving such financing shall be adequate notice. Notwithstanding anything herein to the contrary, prior to the Discharge of the
Senior Obligations, each Second Priority Representative, for itself and on behalf of each other Second Priority Secured Party under its Second Priority Debt Facility, agrees that unless no Senior Secured Party has committed or consented to provide
or provided, or consented to or supported any other Person committing to provide or providing, any DIP Financing, no such Second Priority Secured Party will (x) commit or consent to provide, or

  

Exhibit R to the Credit Agreement 

  
 - 23 -

 
provide, any DIP Financing, without the prior written consent of the Senior Collateral Agent and the Majority Senior Parties or (y) consent to or support any other Person (other than the
Senior Collateral Agent or any Senior Representative or other Secured Party as provided in the immediately preceding sentence) committing to provide or providing any DIP Financing which is not supported by the Senior Collateral Agent and the
Majority Senior Parties. 
 SECTION 6.03. Relief from the Automatic Stay. Until the Discharge of Senior Obligations has
occurred, each Second Priority Representative, for itself and on behalf of each Second Priority Secured Party under its Second Priority Debt Facility, agrees that (a) none of them shall seek relief from the automatic stay or any other stay in
any Insolvency or Liquidation Proceeding or take any action in derogation thereof, in each case in respect of any Shared Collateral, without the prior written consent of the Senior Collateral Agent and (b) it will raise no objection to, and
will not support any objection to, and will not otherwise contest any motion for relief from the automatic stay or from any injunction against foreclosure or enforcement in respect of Senior Obligations made by the Senior Collateral Agent or any
holder of Senior Obligations. 
 SECTION 6.04. Adequate Protection. Each Second Priority Representative, for itself and
on behalf of each Second Priority Secured Party under its Second Priority Debt Facility, agrees that none of them shall object, contest, support or join with any other Person objecting to or contesting (a) any request by the Senior Collateral
Agent, the Senior Representatives or the Senior Secured Parties for adequate protection, (b) any objection by the Senior Collateral Agent, the Senior Representatives or the Senior Secured Parties to any motion, relief, action or proceeding
based on the Senior Collateral Agent’s or any Senior Representative’s or Senior Secured Party’s claiming a lack of adequate protection or (c) the payment of interest, fees, expenses or other amounts of the Senior Collateral
Agent, any Senior Representative or any other Senior Secured Party under Section 506(b) or 506(c) of the Bankruptcy Code or any similar provision of any other Bankruptcy Law. Each Second Priority Representative, on behalf of itself and the
other Second Priority Secured Parties, further agrees that, prior to the Discharge of Senior Obligations, none of them shall assert or enforce any claim under Section 506(b) or 506(c) of the Bankruptcy Code or otherwise that is senior to or on
a parity with the Senior Liens for costs or expenses of preserving or disposing of any Shared Collateral. Notwithstanding anything contained in this Section 6.04 or Section 6.02, in any Insolvency or Liquidation Proceeding, (i) the
Second Priority Representative and the Second Priority Secured Parties may seek, support, accept or retain adequate protection (A) only if the Senior Secured Parties are granted adequate protection that includes replacement liens on additional
collateral and superpriority claims and the Senior Collateral Agent does not object to the adequate protection being provided to the Senior Secured Parties and (B) solely in the form of (1) a replacement Lien on such additional collateral,
subordinated to the Liens securing the Senior Obligations and such DIP Financing on the same basis as the other Liens securing the Second Priority Obligations are so subordinated to the Senior Obligations under this Agreement and
(2) superpriority claims junior in all respects to the superpriority claims granted to the Senior Secured Parties; provided, however, that the Second Priority Representative shall have irrevocably agreed, pursuant to
Section 1129(a)(9) of the Bankruptcy Code, on behalf of itself and the Second Priority Secured Parties for which it is acting, in any stipulation and/or order granting such adequate protection, that such junior superpriority claims may be paid,
under any Plan under Chapter 11 of the Bankruptcy Code that the First Lien Lenders and First Lien Agent support, in any combination of cash, debt, equity or other property, and (ii) in the event any Second Priority Representative, on behalf of
itself and the Second Priority Secured Parties, receives adequate protection, including in the form of additional collateral, then such Second Priority Representative, on behalf of itself and the Second Priority Secured Parties, agrees that the
Senior Secured Parties shall have a senior Lien and claim on such adequate protection as security for the Senior Obligations and that any Lien on any additional collateral securing the Second Priority Obligations shall be subordinated to the Liens
on such Collateral securing the Senior Obligations and any DIP Financing (and all Obligations relating thereto) and any other Liens granted to the Senior Secured Parties as adequate protection, with such subordination to be on the same terms that
the other Liens securing the Second Priority Obligations are subordinated to such Senior Obligations under this Agreement.

 SECTION 6.05. Avoidance Issues. If any Senior Secured Party is required in any
Insolvency or Liquidation Proceeding or otherwise to disgorge, turn over or otherwise pay to the estate of any Grantor, because such amount was avoided or ordered to be paid or disgorged for any reason, including without limitation because it was
found to be a fraudulent or preferential transfer, any amount (a “Recovery”), whether received as proceeds of security, enforcement of any right of set-off or otherwise, then the Senior Obligations shall be reinstated to the extent
of such Recovery and deemed to be outstanding as if such payment had not occurred and the Discharge of Senior Obligations shall be deemed not to have occurred. If this Agreement shall have been terminated prior to such Recovery, this Agreement shall
be reinstated in full force and effect, and such prior termination shall not diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto. The Second Priority Secured Parties agree that none of them shall be
entitled to benefit from any avoidance action affecting or otherwise relating to any distribution or allocation made in accordance with this Agreement, whether by preference or otherwise, it being understood and agreed that the benefit of such
avoidance action otherwise allocable to them shall instead be allocated and turned over for application in accordance with the priorities set forth in this Agreement. Any Shared Collateral or proceeds thereof received by any Second Priority Secured
Party prior to the time of such Recovery shall be deemed to have been received prior to the Discharge of Senior Obligations and subject to the provisions of Section 4.02. 
 SECTION 6.06. Application. This Agreement shall be applicable prior to and after the commencement of any Insolvency or Liquidation Proceeding. All references herein to any Grantor shall apply to
any trustee for such Person and such Person as debtor in possession. The relative rights as to the Shared Collateral and other Collateral and proceeds thereof shall continue after the filing thereof on the same basis as prior to the date of the
petition, subject to any court order approving the financing of, or use of cash collateral by, any Grantor. 
 SECTION 6.07.
Waivers. Until the Discharge of Senior Obligations has occurred, each Second Priority Representative, on behalf of itself and each applicable Second Priority Secured Party, (a) will not assert or enforce any claim under
Section 506(c) of the United States Bankruptcy Code First Priority to or on a parity with the Liens securing the Senior Obligations for costs or expenses of preserving or disposing of any Shared Collateral or other Collateral, and
(b) waives any claim it may now or hereafter have arising out of the election by any Senior Secured Parties of the application of Section 1111(b)(2) of the Bankruptcy Code. 

SECTION 6.08. Asset Dispositions in an Insolvency Proceeding. In an Insolvency or Liquidation Proceeding or otherwise, neither the
Second Priority Representative nor any other Second Priority Secured Party shall oppose any sale or disposition of any Shared Collateral that is consented to or supported by the requisite Senior Secured Parties, and the Second Priority
Representative and each other Second Priority Secured Party will be deemed to have consented under Section 363 of the Bankruptcy Code (and otherwise) to any sale supported by the requisite Senior Secured Parties and to have released their Liens
on such assets; provided that, in connection with any such sale or disposition, (a) each Second Priority Representative retains the right, if and to the extent permitted by applicable law, to credit bid pursuant to Section 363(k) of
the Bankruptcy Code and (b) the proceeds of such sale or disposition are applied in accordance with the terms of Section 4.01. 
 SECTION 6.09. Separate Grants of Security and Separate Classifications. Each Party acknowledges and agrees that (a) the grants of Liens pursuant to the Senior Collateral Documents and the
Second Priority Collateral Documents constitute two separate and distinct grants of Liens and (b) because of, among other things, their differing rights in the Shared Collateral, the Second Priority Debt

  

Exhibit R to the Credit Agreement 

  
 - 25 -

 
Obligations are fundamentally different from the Senior Obligations and must be separately classified in any plan of reorganization proposed or adopted in an Insolvency or Liquidation Proceeding.
To further effectuate the intent of the parties as provided in the immediately preceding sentence, if it is held that the claims of the Senior Secured Parties and the Second Priority Secured Parties in respect of the Shared Collateral constitute
only one secured claim (rather than separate classes of senior and junior secured claims), then each Second Priority Representative, for itself and on behalf of each Second Priority Secured Party under its Second Priority Debt Facility, hereby
acknowledges and agrees that all distributions shall be made as if there were separate classes of senior and junior secured claims against the Grantors in respect of the Shared Collateral (with the effect being that, to the extent that the aggregate
value of the Shared Collateral is sufficient (for this purpose ignoring all claims held by the Second Priority Secured Parties), the Senior Secured Parties shall be entitled to receive, in addition to amounts distributed to them in respect of
principal, pre-petition interest and other claims, all amounts owing in respect of post-petition interest (whether or not allowed or allowable) before any distribution is made in respect of the Second Priority Debt Obligations, with each Second
Priority Representative, for itself and on behalf of each Second Priority Secured Party under its Second Priority Debt Facility, hereby acknowledging and agreeing to turn over to the Senior Collateral Agent amounts otherwise received or receivable
by them to the extent necessary to effectuate the intent of this Section 6.09, even if such turnover has the effect of reducing the claim or recovery of the Second Priority Secured Parties. Neither any Second Priority Representative nor any
Second Priority Secured Party shall oppose or seek to challenge any claim by the Senior Collateral Agent or any Senior Secured Party for allowance in any Insolvency or Liquidation Proceeding of Senior Obligations consisting of post-petition
interest, fees or expenses to the extent of the value of the Senior Secured Party’s Lien, without regard to the existence of the Lien of any Second Priority Agent on behalf of the Second Priority Secured Parties on the Shared Collateral.

 SECTION 6.10. No Waivers of Rights of Senior Secured Parties. Nothing contained herein shall prohibit or in any way
limit the Senior Collateral Agent, any Senior Representative or any other Senior Secured Party from objecting in any Insolvency or Liquidation Proceeding or otherwise to any action taken by any Second Priority Secured Party inconsistent with the
terms of this Agreement, including the seeking by any Second Priority Secured Party of adequate protection or the assertion by any Second Priority Secured Party of any of its rights and remedies under the Second Priority Documents or otherwise.

 SECTION 6.11. Plans of Reorganization. No Second Priority Secured Party shall file, propose, support or vote in favor
of any plan of reorganization (and each shall vote and shall be deemed to have voted to reject any plan of reorganization) unless such plan (i) pays off, in cash in full, all Senior Obligations or (ii) is accepted by the Majority Senior
Parties and is supported by each Senior Representative. To the extent that any Second Priority Secured Party attempts to vote or votes in favor of any plan or reorganization in a manner inconsistent with this Section 6.11, such Second Priority
Secured Party irrevocably agrees that the Senior Collateral Agent may be, and may be deemed, an “authorized agent” of such party under Bankruptcy Rules 3018(c) and 9010, and that the Senior Collateral Agent shall be authorized and entitled
to submit a superseding ballot on behalf of such Second Priority Secured Party that is consistent herewith. 
 SECTION 6.12.
Other Matters. Except as set forth in Sections 6.01, 6.02, 6.04 and 6.08 hereof, to the extent that any Second Priority Representative or any Second Priority Secured Party has or acquires rights under Section 363 or Section 364 of
the Bankruptcy Code or any similar provision of any other Bankruptcy Law with respect to any of the Shared Collateral, such Second Priority Representative, on behalf of itself and each Second Priority Secured Party under its Second Priority Debt
Facility, agrees not to assert any such rights without the prior written consent of the Senior Collateral Agent; provided that if requested by the Senior Collateral Agent, such Second Priority Representative shall timely exercise

  

Exhibit R to the Credit Agreement 

  
 - 26 -

 
such rights in the manner requested by the Senior Collateral Agent, including any rights to payments in respect of such rights. Notwithstanding the foregoing, nothing in this Section 6.12
shall be interpreted to broaden or expand the rights provided in, or waive any limitations, restrictions or prohibitions contained in, Sections 6.01, 6.02, 6.04 or 6.08 hereof. 

SECTION 6.13. Reorganization Securities. If, in any Insolvency or Liquidation Proceeding, debt obligations of any reorganized
debtor secured by Liens upon any property of such reorganized debtor are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of both the Senior Obligations and the Second Priority Debt Obligations,
then, to the extent the debt obligations distributed on account of the Senior Obligations and on account of the Second Priority Debt Obligations are secured by Liens upon the same assets or property, the provisions of this Agreement will survive the
distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations. 
 SECTION 6.14. Effectiveness in Insolvency Proceeding. This Agreement, which the parties hereto expressly acknowledge is a “subordination agreement” under Section 510(a) of the
Bankruptcy Code or any similar provision of any other Bankruptcy Law, shall be effective before, during and after the commencement of any Insolvency or Liquidation Proceeding. 
 ARTICLE VII 
 Reliance; etc. 

SECTION 7.01. Reliance. All loans and other extensions of credit made or deemed made on and after the date hereof by the Senior
Secured Parties to U.S. Holdings, the Company or any other Grantor shall be deemed to have been given and made in reliance upon this Agreement. Each Second Priority Representative, on behalf of itself and each Second Priority Secured Party under its
Second Priority Debt Facility, acknowledges that it and such Second Priority Secured Parties have, independently and without reliance on the Senior Collateral Agent or any Senior Representative or other Senior Secured Party, and based on documents
and information deemed by them appropriate, made their own credit analysis and decision to enter into the Second Priority Debt Documents to which they are party or by which they are bound, this Agreement and the transactions contemplated hereby and
thereby, and they will continue to make their own credit decision in taking or not taking any action under the Second Priority Debt Documents or this Agreement. 
 SECTION 7.02. No Warranties or Liability. Each Second Priority Representative, on behalf of itself and each Second Priority Secured Party under its Second Priority Debt Facility, acknowledges and
agrees that neither the Senior Collateral Agent nor any Senior Representative or other Senior Secured Party has made any express or implied representation or warranty, including with respect to the execution, validity, legality, completeness,
collectibility or enforceability of any of the Senior Debt Documents, the ownership of any Shared Collateral or the perfection or priority of any Liens thereon. The Senior Secured Parties will be entitled to manage and supervise their respective
loans and extensions of credit under the Senior Debt Documents in accordance with law and as they may otherwise, in their sole discretion, deem appropriate, and the Senior Secured Parties may manage their loans and extensions of credit without
regard to any rights or interests that the Second Priority Representatives and the Second Priority Secured Parties have in the Shared Collateral or otherwise, except as otherwise provided in this Agreement. Neither the Senior Collateral Agent nor
any Senior Representative or other Senior Secured Party shall have any duty to any Second Priority Representative or Second Priority Secured Party to act or refrain from acting in a manner that allows, or results in, the occurrence or continuance of
an event of default or default under any agreement with the Company or any other Grantor (including the Second Priority Debt Documents), regardless of any knowledge thereof that they may have or be charged with.

  

Exhibit R to the Credit Agreement

Except as expressly set forth in this Agreement, the Senior Collateral Agent, the Senior Representatives, the Senior Secured Parties, the Second Priority Representatives and the Second Priority
Secured Parties have not otherwise made to each other, nor do they hereby make to each other, any warranties, express or implied, nor do they assume any liability to each other with respect to (a) the enforceability, validity, value or
collectibility of any of the Senior Obligations, the Second Priority Debt Obligations or any guarantee or security which may have been granted to any of them in connection therewith, (b) any Grantor’s title to or right to transfer any of
the Shared Collateral or (c) any other matter except as expressly set forth in this Agreement. 
 SECTION 7.03.
Obligations Unconditional. All rights, interests, agreements and obligations of the Senior Collateral Agent, the Senior Representatives, the Senior Secured Parties, the Second Priority Representatives and the Second Priority Secured Parties
hereunder shall remain in full force and effect irrespective of: 
 (a) any lack of validity or enforceability of any Senior
Debt Document or any Second Priority Debt Document; 
 (b) any change in the time, manner or place of payment of, or in any
other terms of, all or any of the Senior Obligations or Second Priority Debt Obligations, or any amendment or waiver or other modification, including any increase in the amount thereof, whether by course of conduct or otherwise, of the terms of the
Credit Agreement or any other Senior Debt Document or of the terms of any Second Priority Debt Document; 
 (c) any exchange of
any security interest in any Shared Collateral or any other Collateral or any amendment, waiver or other modification, whether in writing or by course of conduct or otherwise, of all or any of the Senior Obligations or Second Priority Debt
Obligations or any guarantee thereof; 
 (d) the commencement of any Insolvency or Liquidation Proceeding in respect of the
Company or any other Grantor; or 
 (e) any other circumstances that otherwise might constitute a defense available to, or a
discharge of, (i) the Company or any other Grantor in respect of the Senior Obligations or (ii) any Second Priority Representative or Second Priority Secured Party in respect of this Agreement. 

ARTICLE VIII 

Miscellaneous 
 SECTION 8.01. Conflicts. Subject to Section 8.18, in the event of any conflict between the provisions of this Agreement and the provisions of any Senior Debt Document or any Second Priority
Debt Document, the provisions of this Agreement shall govern. 
 SECTION 8.02. Continuing Nature of this Agreement;
Severability. Subject to Section 6.05, this Agreement shall continue to be effective until Discharge of Senior Obligations and the indefeasible payment in full of the Second Priority Debt Obligations shall have occurred. This is a
continuing agreement of Lien subordination, and the Senior Secured Parties may continue, at any time and without notice to the Second Priority Representatives or any Second Priority Secured Party, to extend credit and other financial accommodations
and lend monies to or for the benefit of the Company or any other Grantor constituting Senior Obligations in reliance hereon. The terms of this Agreement shall survive and continue in full force and effect in any Insolvency or Liquidation
Proceeding. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining 

 
 Exhibit R to the Credit Agreement 

  
 - 28 -

 
provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 

SECTION 8.03. Amendments; Waivers. (a) No failure or delay on the part of any party hereto 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 parties hereto 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 any party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 8.03, and then such waiver or consent shall be effective only in the specific instance and for the purpose
for which given. No notice or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in similar or other circumstances. 
 (b) The Majority Senior Parties (or the Senior Collateral Agent acting with the approval of the Majority Senior Parties) and the Second Priority Instructing Group (and with respect to any such amendment,
supplement or waiver (i) which by the terms of this Agreement requires the Company’s consent or which increases the obligations or reduces the rights of the Company or any other Grantor, with the consent of the Company, (ii) which by
the terms of this Agreement requires the consent of any Second Priority Representative or which increases the obligations or reduces the rights of a Second Priority Representative, with the consent of such Second Priority Representative,
(iii) which by its terms adversely affects the rights of the Second Priority Secured Parties under a particular Second Priority Debt Facility, in a manner materially different from its effect on the other Second Priority Debt Facilities, with
the consent of the Representative for such Second Priority Debt Facility and (iv) which by its terms adversely affects the rights of the Senior Secured Parties under a particular Senior Debt Facility in a manner materially different from its
effect on the other Senior Debt Facilities, with the consent of the Representative for such Senior Debt Facility) may from time to time amend, supplement or waive any provision hereof. Any such amendment, supplement or waiver shall be in writing and
shall be binding upon the Senior Secured Parties and the Second Priority Secured Parties and their respective successors and assigns. 
 (c) Notwithstanding the foregoing, without the consent of any Secured Party, any Representative may become a party hereto by execution and delivery of a Joinder Agreement in accordance with
Section 8.09 and upon such execution and delivery, such Representative and the Secured Parties and Senior Obligations or Second Priority Debt Obligations of the Debt Facility for which such Representative is acting shall be subject to the terms
hereof. 
 SECTION 8.04. Information Concerning Financial Condition of the Company and the Subsidiaries. Neither the
Senior Collateral Agent nor any other Senior Secured Party shall have any obligation to any Second Priority Representative or any other Second Priority Secured Party to keep the Second Priority Representative or any Second Priority Secured Party
informed of, and the Second Priority Representatives and the Second Priority Secured Parties shall not be entitled to rely on the Senior Collateral Agent or the Senior Secured Parties with respect to, (a) the financial condition of the Company
and the Subsidiaries and all endorsers or guarantors of the Senior Obligations or the Second Priority Debt Obligations and (b) all other circumstances bearing upon the risk of nonpayment of the Senior Obligations or the Second Priority Debt
Obligations. The Senior Collateral Agent, the Senior Representatives, the Senior Secured Parties, the Second Priority Representatives and the Second Priority Secured Parties shall have no duty to advise any other party hereunder of information known
to it or them regarding such condition or any such circumstances or otherwise. In the event that the Senior Collateral Agent, any Senior Representative, any Senior Secured Party, any Second Priority Representative or any

  

Exhibit R to the Credit Agreement 

  
 - 29 -

 
Second Priority Secured Party, in its sole discretion, undertakes at any time or from time to time to provide any such information to any other party, it shall be under no obligation to
(i) make, and the Senior Collateral Agent, the Senior Representatives, the Senior Secured Parties, the Second Priority Representatives and the Second Priority Secured Parties shall not make or be deemed to have made, any express or implied
representation or warranty, including with respect to the accuracy, completeness, truthfulness or validity of any such information so provided, (ii) provide any additional information or to provide any such information on any subsequent
occasion, (iii) undertake any investigation or (iv) disclose any information that, pursuant to accepted or reasonable commercial finance practices, such party wishes to maintain confidential or is otherwise required to maintain
confidential. 
 SECTION 8.05. Subrogation. Each Second Priority Representative, on behalf of itself and each Second
Priority Secured Party under its Second Priority Debt Facility, hereby waives any rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of Senior Obligations has occurred. 

SECTION 8.06. Application of Payments. Except as otherwise provided herein, all payments received by the Senior Secured Parties
may be applied, reversed and reapplied, in whole or in part, to such part of the Senior Obligations as the Senior Secured Parties, in their sole discretion, deem appropriate, consistent with the terms of the Senior Debt Documents and
Section 4.01. Each Second Priority Representative, on behalf of itself and each applicable Second Priority Secured Party, assents to any such extension or postponement of the time of payment of the Senior Obligations or any part thereof and to
any other indulgence with respect thereto, to any substitution, exchange or release of any security that may at any time secure any part of the Senior Obligations and to the addition or release of any other Person primarily or secondarily liable
therefor. 
 SECTION 8.07. Additional Grantors. The Company agrees that, if any Subsidiary shall become a Grantor after
the date hereof, it will promptly cause such Subsidiary to become party hereto by executing and delivering an instrument in the form of Annex I. Upon such execution and delivery, such Subsidiary will become a Grantor hereunder with the same force
and effect as if originally named as a Grantor herein. The execution and delivery of such instrument shall not require the consent of any other party hereunder, and will be acknowledged by the Designated Second Priority Representative and the Senior
Collateral Agent. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor as a party to this Agreement. 

SECTION 8.08. Dealings with Grantors. Upon any application or demand by the Company or any other Grantor to the Senior Collateral
Agent, the Majority Senior Parties, the Second Priority Instructing Group or the Designated Second Priority Representative to take or permit any action under any of the provisions of this Agreement or under any Collateral Document (if such action is
subject to the provisions hereof), the Company or such Grantor, as appropriate, shall furnish to the Senior Collateral Agent or the Designated Second Priority Representative a certificate of an appropriate officer (an “Officer’s
Certificate”) stating that all conditions precedent, if any, provided for in this Agreement or such Collateral Document, as the case may be, relating to the proposed action have been complied with; provided that, in the case of any
such application or demand as to which the furnishing of such documents is specifically required by any provision of this Agreement or any Collateral Document relating to such particular application or demand, no such additional certificate need be
furnished. 
 SECTION 8.09. Additional Debt Facilities. To the extent, but only to the extent, permitted by the
provisions of the Senior Debt Documents and the Second Priority Debt Documents, the Company may incur or issue and sell one or more series or classes of Second Priority Debt and one or more series or classes of Additional Senior Debt. Any such
additional class or series of Second Priority Debt (the “Second Priority Class Debt”) may be secured by a second priority, subordinated Lien on 

 
 Exhibit R to the Credit Agreement 

  
 - 30 -

 
Shared Collateral, in each case under and pursuant to the relevant Second Priority Collateral Documents for such Second Priority Class Debt, if and subject to the condition that the
Representative of any such Second Priority Class Debt (each, a “Second Priority Class Debt Representative”), acting on behalf of the holders of such Second Priority Class Debt (such Representative and holders in respect of any
Second Priority Class Debt being referred to as the “Second Priority Class Debt Parties”), becomes a party to this Agreement by satisfying conditions (i) through (vi), as applicable, of the immediately succeeding paragraph. Any
such additional class or series of Senior Facilities (the “Senior Class Debt”; and the Senior Class Debt and Second Priority Class Debt, collectively, the “Class Debt”) may be secured by a senior Lien on Shared
Collateral, in each case under and pursuant to the Senior Collateral Documents, if and subject to the condition that the Representative of any such Senior Class Debt (each, a “Senior Class Debt Representative”; and the Senior Class
Debt Representatives and Second Priority Class Debt Representatives, collectively, the “Class Debt Representatives”), acting on behalf of the holders of such Senior Class Debt (such Representative and holders in respect of any such
Senior Class Debt being referred to as the “Senior Class Debt Parties”; and the Senior Class Debt Parties and Second Priority Class Debt Parties, collectively, the “Class Debt Parties”), becomes a party to this
Agreement by satisfying the conditions set forth in clauses (i) through (vi), as applicable, of the immediately succeeding paragraph. In order for a Class Debt Representative to become a party to this Agreement: 

(i) such Class Debt Representative shall have executed and delivered a Joinder Agreement substantially in the form of
Annex II (if such Representative is a Second Priority Class Debt Representative) or Annex III (if such Representative is a Senior Class Debt Representative) (with such changes as may be reasonably approved by the Senior Collateral Agent and such
Class Debt Representative) to the Senior Collateral Agent and the Designated Second Priority Representative pursuant to which it becomes a Representative hereunder, and the Class Debt in respect of which such Class Debt Representative is the
Representative and the related Class Debt Parties become subject hereto and bound hereby; 
 (ii) the Company
shall have delivered to the Senior Collateral Agent and the Designated Second Priority Representative true and complete copies of each of the Second Priority Debt Documents or Senior Debt Documents, as applicable, relating to such Class Debt,
certified as being true and correct by the chief executive officer, president, chief financial officer or treasurer of the Company; 
 (iii) in the case of any Second Priority Class Debt, all filings, recordations and/or amendments or supplements to the Second Priority Collateral Documents necessary or desirable in the opinion of the
Designated Second Priority Representative to confirm and perfect the second priority Liens securing the relevant Second Priority Debt Obligations relating to such Class Debt shall have been made, executed and/or delivered (or, with respect to any
such filings or recordations, acceptable provisions to perform such filings or recordings have been taken in the reasonable judgment of the Designated Second Priority Representative), and all fees and taxes in connection therewith shall have been
paid (or acceptable provisions to make such payments have been taken in the reasonable judgment of the Senior Collateral Agent); 
 (iv) in the case of any Senior Class Debt, all filings, recordations and/or amendments or supplements to the Senior Collateral Documents necessary or desirable in the opinion of the Senior Collateral
Agent to confirm and perfect the Senior Lien securing the relevant Senior Obligations relating to such Class Debt shall have been made, executed and/or delivered (or, with respect to any such filings or recordations, acceptable provisions to perform
such filings or recordings have been taken in the reasonable judgment of the Senior Collateral Agent), and all fees and taxes in connection therewith shall have been paid; and

applicable, relating to such Class Debt shall provide, in a manner reasonably satisfactory to the Senior Collateral Agent and the Designated Second Priority Representative, that each Class Debt Party with respect to such Class Debt will be subject
to and bound by the provisions of this Agreement in its capacity as a holder of such Class Debt. 
 SECTION 8.10. Consent to
