continuation shall be effected by the Borrower by giving the Administrative Agent at the Administrative Agent’s Office prior to 1:00 p.m. (New York City time) at least (i) three Business Days’, in the case of a continuation of, or
conversion to, LIBOR Loans or (ii) one Business Day’s in the case of a conversion into ABR Loans, prior written notice (or telephonic notice promptly confirmed in writing) (each, a “Notice of Conversion or Continuation”)
specifying the Loans to be so converted or continued, the Type of Loans to be converted into or continued and, if such Loans are to be converted into, or continued as, LIBOR Loans, the Interest Period to be initially applicable thereto (if no
Interest Period is selected, the Borrower shall be deemed to have selected an Interest Period of one month’s duration). The Administrative Agent shall give each applicable Lender notice as promptly as practicable of any such proposed
conversion or continuation affecting any of its Loans. 
 (b) If any Default or Event of Default is in existence at the
time of any proposed continuation of any LIBOR Loans and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuation, such LIBOR Loans shall be automatically converted on the
last day of the current Interest Period into ABR Loans. If upon the expiration of any Interest Period in respect of LIBOR Loans, the Borrower has failed to elect a new Interest Period to be applicable thereto as provided in
clause (a) above, the Borrower shall be deemed to have elected to convert such Borrowing of LIBOR Loans into a Borrowing of ABR Loans, effective as of the expiration date of such current Interest Period. 

(c) Notwithstanding anything to the contrary herein, the Borrower may deliver a Notice of Conversion or Continuation pursuant to
which the Borrower elects to irrevocably continue the outstanding principal amount of any Term Loans subject to an interest rate Hedging Agreement as LIBOR Loans for each Interest Period until the expiration of the term of such applicable Hedging
Agreement. 
  

	 	2.7.	Pro Rata Borrowings. 

Each Borrowing of Initial Term Loans under this Agreement shall be made by the Lenders pro rata on the basis of their
then-applicable Initial Term Loan Commitments. Each Borrowing of Delayed Draw Term Loans under this Agreement shall be made by the Lenders pro rata on the basis of their then-applicable Delayed Draw Term Loan Commitments. Each
Borrowing of Deposit L/C Loans under this Agreement shall be made by the Lenders pro rata on the basis of their then-applicable Deposit L/C Loan Commitments. Each Borrowing of Revolving Credit Loans under this Agreement shall be made by
the Lenders pro rata on the basis of their then applicable Revolving Credit Commitments. It is understood that (a) no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that
each Lender severally but not jointly shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder and (b) failure by a Lender to perform any of its
obligations under any of the Credit Documents shall not release any Person from performance of its obligation under any Credit Document. 

  
 -80-

	 	2.8.	Interest. 

 (a) The
unpaid principal amount of each ABR Loan shall bear interest from the date of the Borrowing thereof until maturity (whether by acceleration or otherwise) at a rate per annum that shall at all times be the Applicable ABR Margin plus the
ABR, in each case, in effect from time to time. 
 (b) The unpaid principal amount of each LIBOR Loan shall bear interest
from the date of the Borrowing thereof until maturity thereof (whether by acceleration or otherwise) at a rate per annum that shall at all times be the Applicable LIBOR Margin plus the relevant LIBOR Rate, in each case in effect from
time to time. 
 (c) The unpaid average amount of the Aggregate Posting Advances Outstanding during each Posting Interest
Period shall bear interest from and including the first date of such period to but excluding the first date of the next succeeding Weekly Interest Period at a rate per annum that shall at all times be the relevant LIBOR Rate for such Posting
Interest Period. 
 (d) If all or a portion of (i) the principal amount of any Loan or Posting Advance or
(ii) any interest payable thereon or any other amount hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum (the “Default
Rate”) that is (x) in the case of overdue principal, the rate that would otherwise be applicable thereto plus 2% or (y) in the case of any overdue interest or other amounts due hereunder, to the extent permitted by
Applicable Law, the rate described in Section 2.8(a) (or, in the case of the Posting Facility, the rate described in Section 2.8(c)) plus 2% from the date of such non-payment to the date on which such amount is paid in
full (after as well as before judgment). 
 (e) Interest on each Loan and on each Posting Advance shall accrue from and
including the date of any Borrowing to but excluding the date of any repayment thereof and shall (including Posting Advances) be payable in Dollars; provided that any Loan that is repaid on the same date on which it is made shall bear
interest for one day. Except as provided below, interest shall be payable (i) in respect of each ABR Loan, quarterly in arrears on the tenth Business Day following the end of each March, June, September and December, (ii) in respect
of each LIBOR Loan, on the last day of each Interest Period applicable thereto and, in the case of an Interest Period in excess of three months, on each date occurring at three-month intervals after the first day of such Interest Period,
(iii) in respect of each Loan, (A) on any prepayment; provided that interest on ABR Loans shall only become due pursuant to this subclause (A) if the aggregate principal amount of the ABR Loans then outstanding is repaid in
full, (B) at maturity (whether by acceleration or otherwise) and (C) after such maturity, on demand, and (iv) in respect of each Posting Advance, on each Weekly Interest Payment Date to the Posting Agent, for the account of the
relevant Posting Lenders, the amount of interest applicable to the Posting Interest Period ending on such Weekly Interest Payment Date as computed pursuant to Section 2.8(c) of this Agreement; provided that, to the extent any such
interest payment on any Posting Advance is subject to a netting and/or settlement agreement, such interest payment shall be applied, paid or otherwise netted and/or settled, on behalf of the Borrower, as required thereunder. 

(f) All computations of interest hereunder shall be made in accordance with Section 5.5. 

(g) The Administrative Agent, upon determining the interest rate for any Borrowing of LIBOR Loans, shall promptly notify the
Borrower and 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 a.m. (New York City time) on the relevant Weekly Interest Payment Date. Notice of such amount may be provided by email at the address set forth on Schedule 13.2. 

  
 -81-

 (i) In the event that the Administrative Agent or the Borrower determine that any
Section 9.1 Financials previously delivered were incorrect or inaccurate and such inaccuracy, if corrected, 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 Applicable LIBOR Margin applied for such Applicable Period, then (i) the Borrower shall as soon as practicable deliver to the Administrative Agent the correct Section 9.1 Financials for
such Applicable Period, (ii) the Applicable ABR Margin or Applicable LIBOR Margin, as the case may be, shall be determined as if the pricing level for such higher Applicable ABR Margin or Applicable LIBOR Margin, as the case may be, were
applicable for such Applicable Period, and (iii) the Borrower shall within 15 days after delivery of such financial statements pay to the Administrative Agent the accrued additional interest owing as a result of such increased Applicable ABR
Margin or Applicable LIBOR Margin, as the case may be, for such Applicable Period, which payment shall be promptly applied by the Administrative Agent in accordance with this Agreement. This Section 2.8(i) shall not limit the rights
of the Administrative Agent and Lenders with respect to Section 2.8(d) and Section 11. 

(j) Within 20 Business Days following the end of each March, June, September and December (commencing with December 31, 2007),
(i) if the Shortfall Amount at the end of such month is positive, the Administrative Agent shall pay to the Borrower an amount equal to such Shortfall Amount and (ii) if the Shortfall Amount at the end of such month 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 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”). 
  

	 	2.9.	Interest Periods. 

 At the
time the Borrower gives a Notice of Borrowing or Notice of Conversion or Continuation in respect of the making of, or conversion into or continuation as, a Borrowing of LIBOR Loans in accordance with Section 2.6(a), the Borrower shall
give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of the Interest Period applicable to such Borrowing, which Interest Period shall, at the option of the Borrower be a one, two, three or six or (if
available to all relevant Lenders participating in the relevant Credit Facility) a nine or twelve month period or a period of less than one month; provided that, notwithstanding the foregoing, the initial Interest Period beginning on the
Closing Date may be for a period of less than one month if agreed upon by the Borrower and the Administrative Agent. 

Notwithstanding anything to the contrary contained above: 
 (a) the initial Interest Period for any Borrowing of LIBOR Loans shall commence on the date of such Borrowing (including the date of any conversion from a Borrowing of ABR Loans) and each Interest
Period occurring thereafter in respect of such Borrowing shall commence on the day on which the next preceding Interest Period expires; 
 (b) if any Interest Period relating to a Borrowing of LIBOR Loans begins on the last Business Day of a calendar month or begins on a day for which there is no numerically corresponding day in the
calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of the calendar month at the end of such Interest Period; 

  
 -82-

 (c) if any Interest Period would otherwise expire on a day that is not a Business Day,
such Interest Period shall expire on the next succeeding Business Day; provided that if any Interest Period in respect of a LIBOR Loan would otherwise expire on a day that is not a Business Day but is a day of the month after which no further
Business Day occurs in such month, such Interest Period shall expire on the next preceding Business Day; 
 (d) the
Borrower shall not be entitled to elect any Interest Period in respect of any LIBOR Loan if such Interest Period would extend beyond the applicable Maturity Date of such Loan; and 

(e) Posting Interest Periods shall be governed by Section 14. 

 

	 	2.10.	Increased Costs, Illegality, Etc. 

 (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): 

(i) on any date for determining the LIBOR Rate for any Interest Period or on the date for determining the LIBOR Rate
for any Posting Interest Period that (x) deposits in the principal amounts and currencies of the Loans or Posting Advances, as applicable, comprising such LIBOR Borrowing or Posting Advance, as the case may be, are not generally available in
the relevant market or (y) by reason of any changes arising on or after the Closing Date affecting the interbank LIBOR market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the
definition of LIBOR Rate; or 
 (ii) at any time, that such Lender shall incur increased costs or reductions
in the amounts received or receivable hereunder with respect to any LIBOR Loans or with respect to any Posting Advances (other than any increase or reduction attributable to (i) Taxes indemnifiable under Section 5.4, (ii) net
income taxes and franchise and excise taxes (imposed in lieu of net income taxes) imposed on any Agent or Lender or (iii) Taxes included under clauses (c) and (d) of the definition of “Excluded Taxes”) because
of (x) any change since the date hereof in any Applicable Law (or in the interpretation or administration thereof and including the introduction of any new Applicable Law), such as, for example, without limitation, a change in official reserve
requirements, and/or (y) other circumstances affecting the interbank LIBOR market or the position of such Lender in such market; or 
 (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 hereof that
materially and adversely affects the interbank LIBOR market; 

  
 -83-

 then, and in any such event, such Lender (or the Administrative Agent (or, in the case of the Posting
Facility, the Posting Agent), in the case of clause (i) above) shall within a reasonable time thereafter give notice (if by telephone, confirmed in writing) to the Borrower and to the Administrative Agent (or, in the case of the Posting
Facility, the Posting Agent) of such determination (which notice the Administrative Agent (or the Posting Agent, as applicable) shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i)
above, LIBOR Loans or Posting Advances, as applicable, shall no longer be available until such time as the Administrative Agent (or the Posting Agent, as applicable) notifies the Borrower and the Lenders that the circumstances giving rise to such
notice by 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 or the Posting Calculation Agent, as applicable, (y) in the case of clause (ii) above, the Borrower shall pay to such Lender, promptly after receipt of written demand therefor such additional amounts (in the form of an
increased rate of or a different method of calculating, interest or otherwise, as such Lender in its reasonable discretion shall determine) as shall be required to compensate such Lender for such increased costs or reductions in amounts receivable
hereunder (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 the affected LIBOR Loan or the affected Posting Advance, as the case may be, is then being made pursuant to a Borrowing, cancel such Borrowing by giving the Administrative Agent (or the Posting Agent, as applicable) telephonic
notice (confirmed 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 hereof, 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 hereof, 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 hereof. 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 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 pay additional amounts pursuant to this Section 2.10(c) upon receipt of such notice. 

  
 -84-

  

	 	2.11.	Compensation. 

 If
(i) any payment of principal of any LIBOR Loan is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such LIBOR Loan as a result of a payment or conversion pursuant to
Section 2.5, 2.6, 2.10, 5.1, 5.2 or 13.7, as a result of acceleration of the maturity of the Loans pursuant to Section 11 or for any other reason, (ii) any Borrowing of LIBOR Loans is
not made as a result of a withdrawn Notice of Borrowing, (iii) any ABR Loan is not converted into a LIBOR Loan as a result of a withdrawn Notice of Conversion or Continuation, (iv) any LIBOR Loan is not continued as a LIBOR Loan, as the
case may be, as a result of a withdrawn Notice of Conversion or Continuation or (v) any prepayment of principal of any LIBOR Loan is not made as a result of a withdrawn notice of prepayment pursuant to Section 5.1 or 5.2, the
Borrower shall, after receipt of a written request by such Lender (which request shall set forth in reasonable detail the basis for requesting such amount), pay to the Administrative Agent for the account of such Lender any amounts required to
compensate such Lender for any additional losses, costs or expenses that such Lender may reasonably incur as a result of such payment, failure to convert, failure to continue or failure to prepay, including any loss, cost or expense (excluding loss
of anticipated profits) actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such LIBOR Loan. It is agreed and understood that the provisions of this
Section 2.11 shall not apply to any Posting Advances. 
  

	 	2.12.	Change of Lending Office. 

 Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.10(a)(ii), 2.10(a)(iii), 2.10(b), 3.5 or 5.4 with respect to
such Lender, it will, if requested by the Borrower use reasonable 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 the obligations of the Borrower or the right of any Lender provided in Section 2.10, 3.5 or 5.4. 

 

	 	2.13.	Notice of Certain Costs. 

Notwithstanding anything in this Agreement to the contrary, to the extent any notice required by Section 2.10, 2.11,
3.5 or 5.4 is given by any Lender more than 180 days after such Lender has knowledge (or should have had knowledge) of the occurrence of the event giving rise to the additional cost, reduction in amounts, loss, tax or other
additional amounts described in such Sections, such Lender shall not be entitled to compensation under Section 2.10, 2.11, 3.5 or 5.4, as the case may be, for any such amounts incurred or accruing prior to the 181st
day prior to the giving of such notice to the Borrower. 
  

	 	2.14.	Incremental Facilities. 

(a) The Borrower may, at any time or from time to time after the Closing Date, by notice to the Administrative Agent (whereupon the
Administrative Agent shall promptly deliver a copy to each of the Lenders), request (i) one or more additional tranches of term loans (the “Incremental Term Loans”), (ii) one or more additional tranches of deposit l/c
loans (the “Incremental Deposit L/C Loans”), (iii) one or more increases in the amount of the Revolving Credit Commitments (each such increase, an “Incremental Revolving Commitment Increase”) or (iv) one
or more incremental commodity cash collateral posting facilities (each, an “Incremental Posting Facility”); provided that (A) both at the time of any such request and after giving effect to the effectiveness of any
Incremental Amendment referred to below, no Default or Event of Default shall exist and at the time that any such Incremental Term Loan, Incremental Deposit L/C Loan, Incremental Revolving Commitment Increase or Incremental Posting Facility is made
or effected (and after giving effect thereto), no Default or Event of Default shall exist and the conditions in Section 7.1 shall be satisfied and (B) the Borrower shall be in compliance with the covenant set forth in
Section 10.9 determined on a Pro Forma Basis as of the date of the making of such Incremental Term Loan, Incremental Deposit L/C Loans, Incremental Revolving Commitment Increase or the entering into such Incremental Posting Facility, as
the case may be, and as of the last day of the most recent Test Period, in each case as if such Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving Credit Commitment Increase or Incremental Posting Facility, as applicable,
had been outstanding on the last day of such Test Period for testing compliance therewith. 

  
 -85-

 (b) Each tranche of Incremental Term Loans, each tranche of Incremental Deposit L/C
Loans and each Incremental Revolving Commitment Increase shall be in an aggregate principal amount that is 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 the next sentence). Notwithstanding anything to the contrary herein, the aggregate amount of all Incremental Term Loans, Incremental Deposit L/C Loans and the Incremental Revolving Commitment Increases shall not
exceed $2,000,000,000. 
 (c) The Incremental Term Loans (i) 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, the Posting Advances and the Deposit L/C Loans, (ii) shall not mature earlier than the Initial Term Loan Maturity Date, (iii) shall have interest rates
and amortization schedules determined by the Borrower and the lenders thereof and (iv) may have terms and conditions different from those of the Initial Term Loans and the Delayed Draw Term 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. 
 (d) The Incremental Deposit L/C Loans (i) 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, the
Posting Advances and the Deposit L/C Loans, (ii) shall not mature earlier than the Deposit L/C Loan Maturity Date, (iii) shall have interest rates and amortization schedules determined by the Borrower and the lenders thereof and
(iv) may have terms and conditions different from those of the 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, the 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 Credit Increases 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.

  
 -86-

 (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 hereof (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) 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 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 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.

 SECTION 3. Letters of Credit. 

 

	 	3.1.	Issuance of Letters of Credit. 

 (a) Revolving Letters of Credit. (2) 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
Revolving L/C Maturity Date, each Revolving Letter of Credit Issuer agrees, in reliance upon the agreements of the Revolving Credit Lenders set forth in this Section 3, to issue upon the request of the Borrower and for the direct or
indirect 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; (D) each Revolving Letter of Credit shall 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; (F) no Revolving Letter of Credit shall
be issued after the Revolving Letter of Credit Issuer has received a written notice from the Borrower or the Administrative Agent or the Required Lenders stating that a Default or an Event of Default has occurred and is continuing until such
time as the Revolving Letter of Credit Issuer shall have received a written notice (x) of rescission of such notice from the party or parties originally delivering such notice, (y) of the waiver of 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 Letter of Credit shall be issued by
a Revolving Letter of Credit Issuer the Stated Amount of which, when added to the Revolving Letters of Credit Outstandings with respect to such Revolving Letter of Credit Issuer, would exceed the Specified Revolving Letter of Credit Commitment of
such Revolving Letter of Credit Issuer then in effect. 
 (b) Deposit Letters of Credit. (3) 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 Maturity 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. 

  
 -88-

 (ii) Notwithstanding the foregoing, (A) no Deposit Letter of Credit shall be
issued the Stated Amount of which, when added to the Deposit Letters of Credit Outstanding at such time, would exceed the Deposit L/C Loan Collateral Account Balance, (B) 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 Maturity Date, (C) each Deposit Letter of Credit shall be denominated in Dollars, (D) no Deposit Letter of Credit shall be issued if it would be illegal under any Applicable Law for the beneficiary of the Deposit Letter of Credit to

Lenders stating that a Default or an Event of Default has occurred and is continuing until such time as the Deposit Letter of Credit Issuer shall have received a written notice (x) of rescission of such notice from the party or parties
originally delivering such notice, (y) of the waiver of 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. 

 

	 	3.2.	Letter of Credit Requests. 

(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) 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, and in the case of any Deposit
Letter of Credit, the Deposit L/C Maturity 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. 

  
 -89-

 (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) 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 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, 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 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. 

  
 -90-

 (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); 
 (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. 
  

	 	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 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 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 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 Account to be applied to repay in full the amount of such Unpaid Drawing. 

  
 -91-

 In the event that the Borrower fails to Cash Collateralize any Revolving Letter of Credit
that is outstanding on the Revolving Credit Termination Date, the full amount of the Revolving Letters of Credit Outstanding in respect of such Revolving Letter of Credit shall be deemed to be an Unpaid Drawing subject to the provisions of this
Section 3.4 except that the Revolving Letter of Credit Issuer shall hold the proceeds received from the Lenders as contemplated above as cash collateral for such Revolving Letter of Credit to reimburse any Drawing under such Revolving
Letter of Credit and shall use such proceeds first, to reimburse itself for any Drawings made in respect of such Revolving Letter of Credit following the Revolving L/C Maturity Date, second, to the extent such Revolving Letter of Credit expires or
is returned undrawn while any such cash collateral remains, to the repayment of obligations in respect of any Revolving Credit Loans that have not been paid at such time and third, to the Borrower or as otherwise directed by a court of competent
jurisdiction. 
 (b) The obligations of the Borrower under this Section 3.4 to reimburse the Letter of Credit
Issuers with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment that the Borrower or any
other Person may have or have had against any Letter of Credit Issuer, the Administrative Agent or any Lender (including in its capacity as a Revolving L/C Participant), including any defense based upon the failure of any drawing under a Letter of
Credit (each a “Drawing”) to conform to the terms of the Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such Drawing; provided that the Borrower shall not be obligated to
reimburse any Letter of Credit Issuer for any wrongful payment made by such Letter of Credit Issuer under the Letter of Credit issued by it as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such
Letter of Credit Issuer. 
  

	 	3.5.	Increased Costs. 

 If
after the date hereof, the adoption of any Applicable Law, or any change therein, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or actual compliance by a Letter of Credit Issuer or any Revolving L/C Participant with any request or directive made or adopted after the date hereof (whether or not having the force of law), by any such authority, central
bank or comparable agency shall either (a) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against letters of credit issued by any Letter of Credit Issuer, or any Revolving L/C Participant’s
Revolving L/C Participation therein, or (b) impose on any Letter of Credit Issuer or any Revolving L/C Participant any other conditions or liabilities affecting its obligations under this Agreement in respect of Letters of Credit or Revolving
L/C Participations therein or any Letter of Credit or such Revolving L/C Participant’s Revolving L/C Participation therein, and the result of any of the foregoing is to increase the cost to such Letter of Credit Issuer or such Revolving L/C
Participant of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Letter of Credit Issuer or such Revolving L/C Participant hereunder (other than any such increase or
reduction attributable to (i) taxes indemnifiable under Section 5.4, (ii) net income taxes and franchise and excise taxes (imposed in lieu of net income taxes) imposed on any Agent or Lender or (iii) Taxes described in
clauses (c) and (d) of the definition of “Excluded Taxes”) in respect of Letters of Credit or Revolving L/C Participations therein, then, promptly after receipt of written demand to the Borrower by such Letter of
Credit Issuer or such Revolving L/C Participant, as the case may be (a copy of which notice shall be sent by such Letter of Credit Issuer or such Revolving L/C Participant to the Administrative Agent), the Borrower shall pay to such Letter of Credit
Issuer or such Revolving L/C Participant such additional amount or amounts as will compensate such Letter of Credit Issuer or such Revolving L/C Participant for such increased cost or reduction, it being understood and agreed, however, that any
Letter of Credit Issuer or a Revolving L/C Participant shall not be entitled to such compensation as a result of such Person’s compliance with, or pursuant to any request or directive to comply with, any such Applicable Law as in effect on the
date hereof. A certificate submitted to the Borrower by the relevant Letter of Credit Issuer or a Revolving L/C Participant, as the case may be (a copy of which certificate shall be sent by such Letter of Credit Issuer or such Revolving
L/C Participant to the Administrative Agent), setting forth in reasonable detail the basis for the determination of such additional amount or amounts necessary to compensate such Letter of Credit Issuer or such Revolving L/C Participant as
aforesaid shall be conclusive and binding on the Borrower absent clearly demonstrable error. 

  
 -92-

  

	 	3.6.	New or Successor Letter of Credit Issuer. 

 (a) Any Letter of Credit Issuer may resign as a Letter of Credit Issuer upon 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrower. The Borrower may add
Revolving Letter of Credit Issuers and/or Deposit Letter of Credit Issuers at any time upon notice to the Administrative Agent. If a Letter of Credit Issuer shall resign or be replaced, or if the Borrower shall decide to add a new Letter of
Credit Issuer under this Agreement, then the Borrower may appoint from among the Lenders a successor issuer of Letters of Credit under the applicable Credit Facility or a new Letter of Credit Issuer under the applicable Credit Facility, as the case
may be, or, with the consent of the Administrative Agent (such consent not to be unreasonably withheld), another successor or new issuer of Letters of Credit under the applicable Credit Facility, whereupon such successor issuer shall succeed to the
rights, powers and duties of the replaced or resigning Letter of Credit Issuer under this Agreement and the other Credit Documents, or such new issuer of Letters of Credit shall be granted the rights, powers and duties of a Revolving Letter of
Credit Issuer or Deposit Letter of Credit Issuer, as applicable, hereunder, and the term “Revolving Letter of Credit Issuer” or “Deposit Letter of Credit Issuer”, as applicable, shall mean such successor or include such new
issuer of Letters of Credit under the applicable Credit Facility effective upon such appointment. At the time such resignation or replacement shall become effective, the Borrower shall pay to the resigning or replaced Letter of Credit Issuer
all accrued and unpaid fees owing to such Letter of Credit Issuer pursuant to Section 4.1(d). The acceptance of any appointment as a Letter of Credit Issuer hereunder whether as a successor issuer or new issuer of Letters of Credit
in accordance with this Agreement, shall be evidenced by an agreement entered into by such new or successor issuer of Letters of Credit, in a form satisfactory to the Borrower and the Administrative Agent and, from and after the effective date of
such agreement, such new or successor issuer of Letters of Credit shall become a “Revolving Letter of Credit Issuer” or “Deposit Letter of Credit Issuer”, as applicable, hereunder. After the resignation or replacement of a
Letter of Credit Issuer hereunder, the resigning or replaced Letter of Credit Issuer shall remain a party hereto and shall continue to have all the rights and obligations of a Letter of Credit Issuer under this Agreement and the other Credit
Documents with respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit. In connection with any resignation or replacement pursuant to this clause
(a) (but, in case of any such resignation, only to the extent that a successor issuer of Letters of Credit shall have been appointed), either (i) the Borrower, the resigning or replaced Letter of Credit Issuer and the successor issuer
of Letters of Credit shall arrange to have any outstanding Letters of Credit issued by the resigning or replaced Letter of Credit Issuer replaced with Letters of Credit issued by the successor issuer of Letters of Credit or (ii) in the case of
Revolving Letters of Credit, the Borrower shall cause the successor issuer of Revolving Letters of Credit, if such successor issuer is reasonably satisfactory to the 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 this Agreement relating to a Letter of Credit Issuer shall inure
to its benefit as to any actions taken or omitted to be taken by it (A) while it was a Letter of Credit Issuer under this Agreement or (B) at any time with respect to Letters of Credit issued by such Letter of Credit Issuer. 

  
 -93-

 (b) To the extent that there are, at the time of any resignation or 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. 
  

	 	3.7.	Role of Letter of Credit Issuer. 

 Each Lender and the Borrower agree that, in paying any Drawing under a Letter of Credit, the relevant Letter of Credit Issuer shall not have any responsibility to obtain any document (other than any sight
draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the
Letter of Credit Issuers, the Administrative Agent, any of their respective affiliates nor any correspondent, participant or assignee of any Letter of Credit Issuer shall be liable to any Lender for (i) any action taken or omitted in connection
herewith at the request or with the approval of the Required Lenders; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any
document or instrument related to any Letter of Credit or Issuer Document. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided that
this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Letter of Credit Issuers,
the Administrative Agent, any of their respective affiliates nor any correspondent, participant or assignee of any Letter of Credit Issuer shall beliable or responsible for any of the matters described in Section 3.3(d) ; provided
that anything in such Section to the contrary notwithstanding, the Borrower may have a claim against a Letter of Credit Issuer, and such Letter of Credit Issuer may be liable to the 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 thereof, in whole or in part, which may prove to be invalid or
ineffective for any reason. 

  
 -94-

  

	 	3.8.	Cash Collateral. 

(a) Upon the request of the Required Lenders or the Administrative Agent if, as of the Revolving L/C Maturity Date, there are
any Revolving Letters of Credit Outstanding, the Borrower shall immediately Cash Collateralize the then Revolving Letters of Credit Outstanding. 
 (b) If any Event of Default shall occur and be continuing, the Revolving Credit Lenders with Revolving Letter of Credit Exposure representing greater than 50% of the total Revolving Letter of Credit
Exposure or the Administrative Agent may require that the Revolving L/C Obligations be Cash Collateralized. 
 (c) For
purposes of this Section 3.8, Section 5.2(b) and Section 11, “Cash Collateralize” means to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the Revolving Letter
of Credit Issuer and the Revolving Credit Lenders, as collateral for the Revolving L/C Obligations, cash or deposit account balances in an amount equal to 100% of the amount of the Revolving Letters of Credit Outstanding required to be Cash
Collateralized pursuant to documentation in form and substance reasonably satisfactory to the Administrative Agent and the Revolving Letter of Credit Issuer (which documents are hereby consented to by the Revolving Credit Lenders). Derivatives
of such terms have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the Revolving Letter of Credit Issuer and the Revolving L/C Participants, a security interest in all such cash, deposit
accounts and all balances therein and all proceeds of the documentation in form and substance reasonably satisfactory to the Administrative Agent and the Revolving Letters of Credit Issuer (which documents are hereby consented to by the Revolving
Credit Lenders). Such cash collateral shall be maintained in blocked, interest bearing deposit accounts established by and in the name of the Administrative Agent. 

 

	 	3.9.	Deposit L/C Loan Collateral Account. 

 On the Closing Date, the Borrower shall establish the Deposit L/C Loan Collateral Account for the purpose of cash collateralizing the Borrower’s obligations to the Deposit Letter of Credit Issuer in
respect of the Deposit Letters of Credit. On the Closing Date, the proceeds of the Deposit L/C Loans, together with other funds (if any) provided by the Borrower, shall be deposited into the Deposit L/C Loan Collateral Account such that, and
the Borrower agrees that at all times thereafter, and shall immediately cause additional funds to be deposited and held in the Deposit L/C Loan Collateral Account from time to time in order that, the Deposit L/C Loan Collateral Account Balance shall
at least equal the Deposit Letters of Credit Outstanding. The Borrower hereby grants to the Collateral Agent, for the benefit of the Deposit Letter of Credit Issuer, a security interest in the Deposit L/C Loan Collateral Account and all cash
and balances therein and all proceeds of the foregoing, as security for the Deposit L/C Obligations (and, in addition, grants a security interest therein, for the benefit of the Secured Parties as collateral security for the Obligations;
provided that amounts on deposit in the Deposit L/C Loan Collateral Account shall be applied, first, to repay the Deposit L/C Obligations and, then, all other Obligations). Except as expressly provided herein or in any other Credit
Document, no Person shall have the right to make any withdrawal from the Deposit L/C Loan Collateral Account or to exercise any right or power with respect thereto; provided that at any time the Borrower shall fail to reimburse any Deposit
Letter of Credit Issuer for any Unpaid Drawing in accordance with Section 3.4(a), the Borrower hereby absolutely, unconditionally and irrevocably agrees that the Collateral Agent shall be entitled to instruct the depositary bank (the
“Depositary Bank”) of the Deposit L/C Loan Collateral Account to withdraw therefrom and pay to the Administrative Agent for account of such Deposit Letter of Credit Issuer amounts equal to such Unpaid Drawings. Amounts in the
Deposit L/C Loan Collateral Account shall be invested by the Depositary Bank in the manner as instructed by the Administrative Agent (and agreed to by the Depositary Bank). To the extent amounts are invested in Deposit L/C Permitted
Investments, the Borrower shall bear the risk of loss of principal with respect to any such investments. To the extent amounts are invested in anything other than Deposit L/C Permitted Investments, the Administrative Agent shall bear the risk
of loss of principal with respect to any such investments. So long as no Event of Default shall have occurred and be continuing, upon at least three Business Days’ prior written notice to the Collateral Agent and the Administrative Agent,
the Borrower may, at any time and from time to time, request release of and payment to the Borrower of (and the Collateral Agent hereby agrees to instruct the Depositary Bank to release and pay to the Borrower) any amounts on deposit in the Deposit
L/C Loan Collateral Account in excess of the Deposit Letter of Credit Commitment (reduced by the aggregate amounts withdrawn by the Deposit Letter of Credit Issuer and not subsequently deposited by the Borrower), (provided that the Collateral
Agent shall have received prior confirmation of the amount of such excess from the Administrative Agent). In addition, the Collateral Agent hereby agrees to instruct the Depositary Bank to release and pay to the Borrower amounts (if any)
remaining on deposit in the Deposit L/C Loan Collateral Account after the termination or cancellation of all Deposit Letters of Credit and the repayment in full of all outstanding Deposit L/C Loans and Deposit L/C Obligations.

	 	3.10.	Existing Letters of Credit. 

 Subject to the terms and conditions hereof, (a) each Existing Letter of Credit that is outstanding on the Closing Date, listed on Schedule 1.1(b) and denoted thereon as a “Deposit Letter
of Credit” shall, effective as of the Closing Date and without any further action by the Borrower, be continued as a Deposit Letter of Credit hereunder and from and after the Closing Date shall be deemed a Deposit Letter of Credit for all
purposes hereof and shall be subject to and governed by the terms and conditions hereof and (b) each Existing Letter of Credit that is outstanding on the Closing Date, listed on Schedule 1.1(b) and denoted thereon as a
“Revolving Letter of Credit” shall, effective as of the Closing Date and without any further action by the Borrower, be continued as a Revolving Letter of Credit hereunder and from and after the Closing Date shall be deemed a Revolving
Letter of Credit for all purposes hereof and shall be subject to and governed by the terms and conditions hereof. 
  

	 	3.11.	Applicability of ISP and UCP. 

 Unless otherwise expressly agreed by the relevant Letter of Credit Issuer and the Borrower when a Letter of Credit is issued (including any such agreement applicable to an Existing Letter of Credit),
(i) the rules of the ISP shall apply to each Standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber of Commerce at the time of
issuance, shall apply to each Commercial Letter of Credit, and in each case to the extent not inconsistent with the above referred rules, the laws of the State of New York shall apply to each Letter of Credit. 

 

	 	3.12.	Conflict with Issuer Documents. 

 In the event of any conflict between the terms hereof and the terms of any Issuer Document, the terms hereof shall control. 

 

	 	3.13.	Letters of Credit Issued for Others. 

 Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, the Parent or its other Subsidiaries, US Holdings or a Restricted
Subsidiary, the Borrower shall be obligated to reimburse the relevant Letter of Credit Issuer hereunder for any and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the issuance of Letters of Credit for the

 (b) In the event that the Initial Tranche B-3 Term Loans are repaid (the
“Repaid Tranche B-3 Loans”) prior to the date which is 3 years following the Closing Date in whole or in part (other than pursuant to Section 5.2(a)(ii)), the Borrower shall pay to Term Lenders having such Repaid Tranche
B-3 Loans, the Applicable Premium as of the date of such prepayment; provided that prior to the date which is 3 years following the Closing Date, the Borrower may, at its option, on one or more occasions repay up to 35% of the aggregate

amendment, amendment and restatement or other modification of this Agreement which reduces the Applicable ABR Margin or the Applicable LIBOR Margin with respect to the Initial Tranche B-2 Term Loans or any prepayment or refinancing of the Initial
Tranche B-2 Term Loans with proceeds of new term loans having lower applicable margins or applicable yield (after giving effect to any premiums paid on such new term loans) than the Applicable ABR Margin or the Applicable LIBOR Margin for the
Initial Tranche B-2 Term Loans as of the Closing Date, each such amendment, amendment and restatement, modification, prepayment or refinancing, as the case may be, shall be accompanied by a fee or prepayment premium, as applicable, equal to
(i) 3%, if such amendment, amendment and restatement, modification, prepayment or refinancing, as the case may be, occurs after the Closing Date but prior to the first anniversary of the Closing Date, (ii) 2%, if such amendment, amendment
and restatement, modification, prepayment or refinancing, as the case may be, occurs on or after the first anniversary of the Closing Date but prior to the second anniversary of the Closing Date and (iii) 1%, if such amendment, amendment and
restatement, modification, prepayment or refinancing, as the case may be, occurs on or after the second anniversary of the Closing Date but prior to the third anniversary of the Closing Date. As a condition to effectiveness of any assignment
pursuant to Section 13.7(b) in respect of any amendment, amendment and restatement or modification to this Agreement effective prior to the third anniversary of the ClosingDate that has the effect of reducing the Applicable ABR Margin or
Applicable LIBOR Margin for the Initial Tranche B-2 Term Loans from the Applicable ABR Margin or Applicable LIBOR Margin in effect on the Closing Date, the Borrower shall pay to such Non-Consenting Lender of Initial Tranche B-2 Term Loans a premium
equal to the premium that would apply if such Non-Consenting Lender’s Initial Tranche B-2 Term Loans being assigned were being prepaid and subject to the premium set forth in the immediately preceding sentence. 

 

	 	5.2.	Mandatory Prepayments. 

(a) Term Loan Prepayments. (1) (A) On each occasion that a Prepayment Event occurs, the Borrower shall, within three

(d) below, Term Loans in a principal amount equal to 100% of the Net Cash Proceeds from such Prepayment Event. (B) In the event that any Initial Tranche B-3 Term Loans are repaid (the “PE Repaid Tranche B-3 Loans”)
prior to the third anniversary of the Closing Date pursuant to this Section 5.2(a)(i), the Borrower shall pay to Term Lenders having such PE Repaid Tranche B-3 Loans, the Applicable Premium as of the date of such prepayment. 

  
 -100-

 (ii) Not later than the date that is ninety days after the last day of any fiscal year
(commencing with and including the fiscal year ending on or about December 31, 2008), the Borrower shall prepay, in accordance with clauses (c) and (d) below, Term Loans in a principal amount equal to (x) 50% of
Excess Cash Flow for such fiscal year; provided that (A) the percentage in this Section 5.2(a)(ii) shall be reduced to 25% if, on the date that such prepayment is required to be made, the Consolidated Total Debt to
Consolidated EBITDA Ratio is less than or equal to 6.00 to 1.0 but greater than 4.75 to 1.0 and (B) no prepayment of any Term Loans shall be required under this Section 5.2(a)(ii) if, on the date that such prepayment is required to
be made, the Consolidated Total Debt to Consolidated EBITDA Ratio is less than or equal to 4.75 to 1.00, minus (y) the principal amount of Term Loans voluntarily prepaid pursuant to Section 5.1 during such fiscal year.

 (b) Repayment of Revolving Credit Loans. If on any date the aggregate amount of the Lenders’ Revolving
Credit Exposures (collectively, the “Aggregate Revolving Credit Outstandings”) for any reason exceeds 100% of the Total Revolving Credit Commitment then in effect, the Borrower shall forthwith repay on such date the principal amount
of any Swingline Loans and, after all Swingline Loans have been paid in full, the Revolving Credit Loans in an amount necessary to eliminate such deficiency. If, after giving effect to the prepayment of all outstanding Swingline Loans and
Revolving Credit Loans, the Aggregate Revolving Credit Outstandings exceed the Total Revolving Credit Commitment then in effect, the Borrower shall Cash Collateralize the Revolving L/C Obligations to the extent of such excess. 

(c) Application to Repayment Amounts. Subject to Section 5.2(h), each prepayment of Term Loans required by
Sections 5.2(a)(i) and (ii) shall be allocated pro rata among the Initial Term Loans, the Delayed Draw Term Loans and the Incremental Term Loans based upon the applicable remaining Repayment Amounts due in respect thereof
and be applied to reduce the scheduled Repayment Amounts in direct order of maturity; provided that, subject to the pro rata application to Repayment Amounts within any Class of Term Loans, the Borrower may allocate such prepayment in its
sole discretion among the Class or Classes of Term Loans as the Borrower may specify. Subject to Section 5.2(h), with respect to each such prepayment, the Borrower will, not later than the date specified in
Section 5.2(a) for making such prepayment, give the Administrative Agent telephonic notice (promptly confirmed in writing and which shall include a calculation of the amount of such prepayment to be applied to eachClass of Term Loans)
requesting that the Administrative Agent provide notice of such prepayment to each Lender of Term Loans. 

(d) Application to Term Loans, Deposit L/C Loans and Incremental Deposit L/C Loans. With respect to each prepayment of
Term Loans, Deposit L/C Loans and Incremental Deposit L/C Loans elected to be made by the Borrower pursuant to Section 5.1 or, in the case of the Term Loans only, required by Sections 5.2(a)(i) and (ii), the Borrower may
designate the Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant to which made; provided that (x) the Borrower pays any amounts, if any, required to be paid pursuant to Section 2.11 with respect to
prepayments of LIBOR Loans made on any date other than the last day of the applicable Interest Period and (y) no prepayment made pursuant to Section 5.1 or Section 5.2(a)(i) and (a)(ii) of Delayed Draw Term Loans
shall be applied to the Delayed Draw Term Loans of any Defaulting Lender. In the absence of a Rejection Notice or a designation by the Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make
such designation in its reasonable discretion with a view, but no obligation, to minimize breakage costs owing under Section 2.11. Upon any prepayment of Deposit L/C Loans, the Deposit Letter of Credit Commitment shall be reduced by
an amount equal to such prepayment and the Borrower shall be permitted to withdraw an amount up to the amount of such prepayment from the Deposit L/C Loan Collateral Account to complete such prepayment; provided that after giving effect to
such withdrawal, the Deposit Letters of Credit Outstanding at such time would not exceed the Deposit L/C Loan Collateral Account Balance. 

  
 -101-

 (e) Application to Revolving Credit Loans. With respect to each prepayment
of Revolving Credit Loans elected to be made by the Borrower pursuant to Section 5.1 or required by Section 5.2(b), the Borrower may designate (i) the Types of Loans that are to be prepaid and the specific Borrowing(s)
pursuant to which made and (ii) the Revolving Credit Loans to be prepaid; provided that (x) each prepayment of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans; and (y) notwithstanding
the provisions of the preceding clause (x), no prepayment made pursuant to Section 5.1 or Section 5.2(b) of Revolving Credit Loans shall be applied to the Revolving Credit Loans of any Defaulting Lender. In the absence
of a designation by the Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its reasonable discretion with a view, but no obligation, to minimize breakage costs owing under
Section 2.11. 
 (f) LIBOR Interest Periods. In lieu of making any payment pursuant to this
Section 5.2 in respect of any LIBOR Loan other than on the last day of the Interest Period therefor so long as no Event of Default shall have occurred and be continuing, the Borrower at its option may deposit with the Administrative
Agent an amount equal to the amount of the LIBOR Loan to be prepaid and such LIBOR Loan shall be repaid on the last day of the Interest Period therefor in the required amount. Such deposit shall be held by the Administrative Agent in a
corporate time deposit account established on terms reasonably satisfactory to the Administrative Agent, earning interest at the then customary rate for accounts of such type. Such deposit shall constitute cash collateral for the LIBOR Loans to
be so prepaid; provided that the Borrower may at any time direct that such deposit be applied to make the applicable payment required pursuant to this Section 5.2. 

(g) Minimum Amount. No prepayment shall be required pursuant to Section 5.2(a)(i) in the case of any
Prepayment Event yielding Net Cash Proceeds of less than $5,000,000 in the aggregate and (ii) unless and until the amount at any time of Net Cash Proceeds from Prepayment Events required to be applied at or prior to such time pursuant to such
Section and not yet applied at or prior to such time to prepay Term Loans pursuant to such Section exceeds (x) $25,000,000 for a single Prepayment Event or (y) $100,000,000 in the aggregate for all Prepayment Events (other than those that
are either under the threshold specified in subclause (i) or over the threshold specified in subclause (ii)(x) ) in any one fiscal year, at which time all such Net Cash Proceeds referred to in this subclause (ii) with
respect to such fiscal year shall be applied as a prepayment in accordance with this Section 5.2. 

(h) Rejection Right. The Borrower shall notify the Administrative Agent in writing of any mandatory prepayment of Term
Loans required to be made pursuant to Section 5.2(a), in each case at least three Business Days prior to the date of such prepayment. Each such notice shall specify the date of such prepayment and provide a reasonably detailed
calculation of the amount of such prepayment. The Administrative Agent will promptly notify each Lender holding Term Loans of the contents of the Borrower’s prepayment notice and of such Lender’s pro rata share of the
prepayment. Each Lender may reject all or a portion of its pro rata share of any such prepayment of Term Loans required to be made pursuant to Section 5.2(a) (such declined amounts, the “Declined Proceeds”)
by providing written notice (each, a “Rejection Notice”) to the Administrative Agent and the Borrower no later than 5:00 p.m. (New York time) one Business Day after the date of such Lender’s receipt of notice from the
Administrative Agent regarding such prepayment. Each Rejection Notice shall specify the principal amount of the mandatory prepayment of Term Loans to be rejected by such Lender. If a Lender fails to deliver a Rejection Notice to the
Administrative Agent within the time frame specified above or such Rejection Notice fails to specify the principal amount of 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”). 

  
 -102-

 (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. 

  
 -103-

 (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.

  
 -104-

 (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 anysums 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). 

  
 -105-

 (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). 
 (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. 

  
 -106-

	 	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. 

  
 -107-

 (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

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

Restricted Subsidiary of the Borrower; provided that neither the Borrower nor any such Restricted Subsidiary shall be required to pay any such tax, assessment, charge, levy or claim that is being contested in good faith and by proper
proceedings if it has maintained adequate reserves (in the good faith judgment of management of the Borrower) with respect thereto in accordance with GAAP or the failure to pay could not reasonably be expected to result in a Material Adverse Effect.

or any Existing Notes with Stated Maturities beyond the latest 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 Amount at the time of such prepayment, repurchase, redemption or other defeasance plus (3) to the extent the
Consolidated Secured Debt to Consolidated EBITDA Ratio is not greater than 5.0 to 1.0 on a Pro Forma Basis, to the making of 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 Additional Debt and (iii) in the case of the Limited Notes, in compliance with
Section 10.1(g). Notwithstanding the foregoing, nothing in this Section 10.7 shall prohibit (A) the repayment or prepayment of intercompany subordinated Indebtedness 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.

  

	 	10.8.	Limitations on Sale Leasebacks.

 (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 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. 

  
 -158-

	 	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 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. 

  
 -159-

	 	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 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, 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. 

  
 -160-

	 	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. 

 (b)
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 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.

  
 -161-

 (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 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. 

  
 -162-

	 	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. 

 iv) 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.

	 	13.1.	Amendments, Waivers and Releases. 

 Neither this Agreement nor any other Credit Document, nor any terms hereof or thereof, may be amended, supplemented or modified except in accordance with the provisions of this
Section 13.1. The Required Lenders may, or, with the written consent of the Required Lenders, the Administrative Agent and/or the Collateral Agent may, from time to time, (a) enter into with the relevant Credit Party or Credit

specifically to the terms or provisions of the Posting Facility (including Schedule 1.1(e)) and does not affect the Security Documents or otherwise alter any other terms or provisions of this Agreement, such amendment, supplement,
modification or waiver shall require the action or consent only of the Required Posting Lenders rather than the Required Lenders and (ii) each such waiver and each such amendment, supplement or modification shall be effective only in the
specific instance and for the specific purpose for which given; and provided, further, that no such waiver and no such amendment, supplement or modification shall 

(i) forgive or reduce any portion of any Loan or Posting Advance or extend the final scheduled maturity date of any
Loan or Posting Advance or reduce the stated rate (it being understood that any change to the definition of Consolidated Total Debt to Consolidated EBITDA Ratio, or Consolidated Secured Debt to Consolidated EBITDA Ratio or Consolidated EBITDA to

at the “default rate” or amend Section 2.8(d)), or forgive any portion, or extend the date for the payment, of any interest or Fee payable hereunder (other than as a result of waiving the applicability of any post-default

(viii) amend Section 2.9 (or any related definitions) so as to permit Interest Period intervals greater
than six months without regard to availability to Lenders, without the written consent of each Lender directly and adversely affected thereby, or

 (x) decrease the amount or allocation of any mandatory prepayment to be received by any Initial Term Loan
Lender without the written consent of the Required Initial Term Loan Lenders, or

 -165-

 (xii) decrease any Delayed Draw Term Loan Repayment Amount, extend any
scheduled Delayed Draw Term Loan Repayment Date or decrease the amount or allocation of any mandatory prepayment to be received by any Lender with a Delayed Draw Term Loan Commitment or an outstanding Delayed Draw Term Loan, in each case without the

In the case of any waiver, US Holdings, the Borrower, the applicable Credit Parties, the Lenders, the Administrative Agent and the
Posting Agent shall be restored to their former positions and rights hereunder and under the other Credit Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing, it being understood that no such waiver

 Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, modification, supplement, waiver or consent hereunder, except that the
Commitment of such Lender may not be increased or extended without the consent of such Lender (it being understood that any Commitments, Loans or Posting Advances held or deemed held by any Defaulting Lender shall be excluded for a vote of the
Lenders hereunder requiring any consent of the Lenders, except as expressly provided for by this Agreement). 
 Notwithstanding
the foregoing, in addition to any credit extensions and related Incremental Amendment(s) effectuated without the consent of Lenders in accordance with Section 2.14, this Agreement may be amended (or amended and restated) with the written
consent of the Required Lenders, the Administrative Agent, the Posting Agent, US Holdings and the Borrower (a) to add one or more additional credit facilities to this Agreement and to permit the extensions of credit from time to time
outstanding thereunder and the accrued interest and fees in respect thereof to share ratably in the benefits of this Agreement and the other Credit Documents with the Loans, Posting Advances and Commitments and the accrued interest and Fees in
respect thereof and (b) to include appropriately the Lenders holding such credit facilities in any determination of the Required Lenders and other definitions related to such new Loans, Posting Advances and Commitments. 

  
 -166-

 In addition, notwithstanding the foregoing, this Agreement may be amended with the written

consent shall not be unreasonably withheld or delayed), and in the case of Revolving Credit Commitments or Revolving Credit Loans, the Swingline Lender or the applicable Revolving Letter of Credit Issuer; provided that no consent of the

 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent or the Posting Agent, as applicable, an administrative questionnaire in a form approved by the Administrative

entitled to the benefits of Sections 2.10, 2.11, 3.5, 5.4 and 13.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this

Agent’s Office a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans, Posting Advances and any payment

Letter of Credit Issuers and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register

assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in clause (b) of this
Section 13.6 (unless waived) and any written consent to such assignment required by clause (b) of this Section 13.6, the Administrative Agent shall accept such Assignment and Acceptance and record the information

Administrative Agent, the Posting Agent, any Letter of Credit Issuer or the Swingline Lender, sell participations to one or more banks or other entities (each, a “Participant”) in all or a portion of such Lender’s rights and
obligations under this Agreement (including all or a portion of its Commitments, Posting Advances and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such
Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) US Holdings, the Borrower, the Administrative Agent, the Posting Agent, the Letter of Credit Issuers and the other Lenders shall

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 first paragraph of
Section 13.1 that affects such Participant. Subject to clause (c)(ii) of this Section 13.6, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.10, 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 agrees to be
subject to Section 13.8(a) as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive
any greater payment under Section 2.10, 2.11, or 5.4 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such
Participant is made with the Borrower’s prior written consent (which consent shall not be unreasonably withheld or delayed). 
 (iii) Each Lender that sells a participation shall, acting for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each participant and the

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. 

  
 -173-

 (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,
K-2-A, K-2-B, K-2-C, K-3 or K-4, evidencing the Revolving Credit Loans and Swingline Loans, Initial Tranche B-1 Term Loans, Initial Tranche B-2 Term Loans, Initial Tranche B-3 Term Loans, Delayed Draw Term Loans
and Deposit L/C Loans, respectively, owing to such Lender. 
 (e) Subject to Section 13.16, the Borrower

derivative transactions to be entered into in connection with or 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 Affiliates pursuant to this Agreement or that has been delivered to such Lender by or on behalf of the Borrower and its Affiliates in connection with such Lender’s credit
evaluation of the Borrower and its Affiliates prior to 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 with out 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.

(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. 
 (b) After the occurrence and during the continuance of an Event of Default, in addition to any rights and remedies of the Lenders provided by Applicable Law, each Lender shall have the right, without
prior notice to US Holdings, the Borrower, any such notice being expressly waived by US Holdings, the Borrower to the extent permitted by Applicable Law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated
maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any 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.

Agent pursuant to the Credit Documents, including, all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (A) relates to a request for a

electronic mail) the Administrative Agent of the posting of any such documents and provide to the Administrative Agent by electronic mail electronic versions (i.e., soft copies) of such documents. Each Lender shall be solely responsible for
timely accessing posted documents or requesting delivery of paper copies of such documents from the Administrative Agent and maintaining its copies of such documents. Nothing in this Section 13.17 shall prejudice the right of US
Holdings, the Borrower, the Administrative Agent, any other Agent or any Lender to give any notice or other communication pursuant to any Credit Document in any other manner specified in such Credit Document. 

  
 -179-

 (b) The Administrative Agent agrees that the receipt of the Communications by the
Administrative Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Administrative Agent for purposes of the Credit Documents. Each Lender agrees that notice to it (as provided in the next
sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Credit Documents. Each Lender agrees (A) to notify the
Administrative Agent in writing (including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notice may be sent by electronic transmission and (B) that the foregoing notice may be sent to
such e-mail address. 
 (c) US Holdings and the Borrower further agree that the Agents may make the Communications
available to the Lenders by posting the Communications on Intralinks or a substantially similar electronic transmission system (the “Platform”), so long as the access to such Platform is limited (i) to the Agents, the Letter of

 (d) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS OR THE
ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE COMMUNICATIONS OR THE PLATFORM. In no event shall any Agent or their Related Parties (collectively, the
“Agent Parties” and each an “Agent Party”) have any liability to US Holdings, the Borrower, any Lender, any Letter of Credit Issuer or any other Person for losses, claims, damages, liabilities or expenses of any
kind (whether in tort, contract or otherwise) arising out of US Holdings’, the Borrower’s or any Agent’s transmission of Communications through the internet, except to the extent the liability of any Agent Party resulted from such
Agent Party’s (or any of its Related Parties’ (other than trustees or advisors)) gross negligence, bad faith or willful misconduct or material breach of the Credit Documents (as determined in a final non-appealable judgment of a court of
competent jurisdiction). 
 (e) The Borrower and each Lender acknowledge that certain of the Lenders may be
“public-side” Lenders (Lenders that do not wish to receive material non-public information with respect to US Holdings, the Borrower, the Subsidiaries of the Borrower or their securities) and, if documents or notices required to be
delivered pursuant to the Credit Documents or otherwise are being distributed through the Platform, any document or notice that US Holdings or the Borrower has indicated contains only publicly available information with respect to US Holdings, the
Borrower and the Subsidiaries of the Borrower and their securities may be posted on that portion of the Platform designated for such public-side Lenders. If US Holdings or the Borrower has not indicated whether a document or notice delivered
contains only publicly available information, the Administrative Agent shall post such document or notice solely on that portion of the Platform designated for Lenders who wish to receive material nonpublic information with respect to US Holdings,
the Borrower, the Subsidiaries of the Borrower and their securities. Notwithstanding the foregoing, US Holdings and the Borrower shall use commercially reasonable efforts to indicate whether any document or notice contains only publicly
available information. 
  

	 	13.18.	USA PATRIOT Act. 

 Each
Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record
information that identifies each Credit Party, which information includes the name and address of each Credit Party and other information that will allow such Lender to identify each Credit Party in accordance with the Patriot Act.

	 	13.19.	Payments Set Aside. 

 To
the extent that any payment by or on behalf of the Borrower is made to any Agent or any Lender, or any Agent or any Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently
invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Agent or such Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection
with any proceeding or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such
setoff had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share of any amount so recovered from or repaid by any Agent, plus interest thereon from the date of such demand
to the date such payment is made at a rate per annum equal to the applicable Overnight Rate from time to time in effect.

 v) The
Secured Parties hereby acknowledge (i) the legal separateness of US Holdings, the Borrower and the Subsidiaries of the Borrower from the Oncor Subsidiaries, (ii) that the lenders under the Oncor Credit Facility and the noteholders under
the Existing Oncor Notes and under the transition bonds have likely advanced funds thereunder in reliance upon the separateness of the Oncor Subsidiaries from US Holdings, the Borrower and the Subsidiaries of the Borrower, (iii) that the Oncor
Subsidiaries have assets and liabilities that are separate from those of US Holdings, the Borrower and the Subsidiaries of the Borrower, (iv) that the Obligations are obligations and liabilities of the Borrower and the other Credit Parties
only, and are not the obligations or liabilities of any of the Oncor Subsidiaries, (v) that the Secured Parties shall look solely to the Borrower and the Guarantors and such Persons’ assets, and not to any assets, or to the pledge of any
assets, owned by any of the Oncor Subsidiaries, for the repayment of any amounts payable pursuant to this Agreement and for satisfaction of any other Obligations and (vi) that none of the Oncor Subsidiaries shall be personally liable to the
Secured Parties for any amounts payable, or any other Obligation, under the Credit Documents. 
 (b) The Secured Parties
hereby acknowledge and agree that the Secured Parties shall not (i) initiate any legal proceeding to procure the appointment of an administrative receiver, or (ii) institute any bankruptcy, reorganization, insolvency, winding up,
liquidation, or any like proceeding under applicable law, against any of the Oncor Subsidiaries, or against any of the Oncor Subsidiaries’ assets. The Secured Parties further acknowledge and agree that each of the Oncor Subsidiaries is a
third party beneficiary of the forgoing covenant and shall have the right to specifically enforce such covenant in any proceeding at law or in equity. 
  

	 	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. 

  
 -181-

 (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); 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. 

  
 -182-

 (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. 

  
 -183-

 (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). 
 (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

	 	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

 (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 

  
 -184-

 (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). 

  
 -185-

 (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). 

(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).

 -188-Separation Agreement and Release

 Exhibit 10.1 
 EXECUTION COPY 
 SEPARATION AGREEMENT AND RELEASE 

The parties to this Separation Agreement and Release (“Agreement”) are Northwest Pipe Company (the “Company”) and
Stephanie J. Welty (“Welty”). 
 RECITALS 

A. Welty’s employment will terminate, effective January 20, 2011. 

B. The Company agrees to provide Welty with severance pay and related benefits under this Agreement under the terms and conditions set
forth below. 
 Therefore, in consideration of the mutual promises set forth below, the parties agree as follows: 

1. Employment Termination. Welty’s employment with the Company is hereby terminated, effective January 20, 2011 (the
“Separation Date”). 
 2. Payment. Welty has received all accrued wages owing through the Separation Date. As
consideration for this Agreement, Welty shall receive the following: 
 2.1 Two-Hundred Forty-Five Thousand and no/100 Dollars
($245,000.00), payable in regular installments as salary continuation for a period of twelve months (the “Severance Period”) in accordance with the Company’s regular payroll schedule, and starting the first pay period following
expiration of the revocation period under Section 6. The Company will also pay Welty a lump sum of One Hundred Thousand and no/100 Dollars ($100,000.00), within ten (10) days after the expiration of the revocation period under
Section 6. The Company will withhold taxes on these amounts in accordance with all applicable local, state and federal laws. 
 2.2 The Company will directly pay the first eighteen months’ premiums for continuation of Welty’s health insurance coverage under COBRA. If Welty should obtain equivalent group coverage she will
notify the company and COBRA payments will be discontinued. 
 2.3 The Company will fully accelerate the vesting of all of the
777 unvested restricted stock units (“RSU’s)” currently held by Welty, effective on the Separation Date, such that 100% of all RSU’s granted to Welty shall be considered fully vested and exercisable at that time. The Performance
Share Agreements dated August 18, 2008 and April 15, 2009 shall terminate effective as of the Separation Date. 
 2.4
Welty agrees to repay all amounts she received as severance under this Section 2 in the event Welty is found by a court of competent jurisdiction to have engaged in intentional or reckless illegal activity in connection with any of the items of
accounting practice, policy, procedures or disclosures that are related to the investigation conducted by the Audit Committee of the Company’s Board of Directors. 

  
 Page 1 - SEPARATION AGREEMENT
AND RELEASE 

 3. Health Insurance. Welty’s coverage under the Company’s health insurance
plan ends on January 31, 2011. If eligible and she properly elects, Welty may continue full health insurance benefits for herself and her immediate family as provided under federal COBRA regulations. Except as set forth in Section 2, Welty
is responsible for all payments under COBRA for continuation of health insurance benefits. 
 4. Employee Pension and
Retirement Plans. Welty shall be entitled to Welty’s rights under the Company’s retirement benefit and other deferred compensation plans as such plans, by their provisions, apply upon Welty’s termination. 

5. General Release. Except as provided below, in consideration of the benefits provided in this Agreement, Welty
releases the Company, its directors, officers, employees, attorneys, insurers, related corporations, successors and assigns from any and all liability, damages or causes of action, whether known or unknown, whether in tort, contract, or under state
or federal statute. Welty understands and acknowledges that this release includes, but is not limited to any claim for reinstatement, reemployment, attorneys’ fees or additional compensation in any form, and any claim, including but not limited
to those, arising under the Rehabilitation Act of 1973, Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, the Post Civil War Civil Rights Act (42 U.S.C. 1981-88), the Equal Pay Act, the Age Discrimination in Employment Act,
the Older Workers Benefit Protection Act, the Americans with Disabilities Act, the Vietnam Era Veterans Readjustment Assistance Act, the Fair Labor Standards Act, the Family Medical Leave Act of 1993, the Uniformed Services Employment and
Re-employment Rights Act, the Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA), the Employee Retirement Income Security Act of 1974 (ERISA), Executive Order 11246, as amended, and the civil rights, employment, and labor laws of any
state and any regulation under such authorities relating to Welty’s employment. The parties specifically exclude and except from this release any indemnity and advancement rights of Welty which arise by virtue of Welty’s position as an
officer or director of the Company and the parties specifically exclude and exempt from this release any rights of Welty under any insurance or indemnity policy covering acts or omissions of the Company’s officers and directors. This Agreement
neither creates, enhances, diminishes or extinguishes any right or entitlement that Welty may subsequently claim to possess with respect to her access to any Company documents, nor any defense the Company may possess with respect to any such claim.

 6. Release of Rights Under Older Workers’ Benefit Protection Act. In accordance with the Age Discrimination in
Employment Act and Older Workers’ Benefit Protection Act (collectively, the “Act”), Welty acknowledges that (1) she has been advised in writing to consult with an attorney prior to executing this Agreement; (2) she is aware
of certain rights to which she may be entitled under the Act; (3) as consideration for executing this Agreement, Welty has received additional benefits and compensation of value to which she would otherwise not be entitled; and (4) by
signing this Agreement, she will not waive rights or claims under the Act which may arise after the execution of this Agreement. Welty acknowledges that she has been given a period of at least 21 days from December 27, 2010, to consider this
offer. A change in the terms of this Agreement shall not restart the 21-day consideration period. Welty further acknowledges that she has a period of seven days from the date of execution in which to revoke this Agreement by written notice to
Richard A. Roman, Chief Executive Officer. In the event Welty does not exercise her right to revoke this Agreement, the Agreement shall become effective on the date immediately following the seven-day waiting period described above. 

  
 Page 2 - SEPARATION AGREEMENT
AND RELEASE 

 7. Obligations of Welty. 

7.1 Return of Company Property. Welty agrees that, on or before the effective date of her termination, she will return to the
Company all property she knows to be in her possession belonging to the Company, including, but not limited to keys, credit cards, telephone calling card, files, records, computer access codes, computer hardware, computer programs, instruction
manuals, business plans, and all other property and documents which Welty prepared or received in connection with her employment with the Company. 
 7.2 Confidentiality. Welty acknowledges that in the course of her employment with the Company, she obtained Confidential Information, i.e., data that has been researched, compiled, developed
and/or maintained by the Company, and that is not generally known within the industry. For the purpose of this Agreement, Confidential Information includes, but is not limited to, trade secrets, information, ideas, knowledge, data, or know-how
related to products, processes, software, designs, formulae, tests, research, business and/or marketing plans and strategies, costs, profits, pricing, personnel and financial information, capitalization and other corporate data and information, and
information about or obtained from customers, authors, suppliers, consultants, licensees, or affiliates. Confidential Information also includes information the Company has received from third parties in confidence. Welty agrees that she will not use
or disclose Confidential Information, in any form, for any purpose, notwithstanding the termination of her employment, unless otherwise authorized by the Company. 
 7.3 Disclosure of this Agreement. Welty shall keep the terms of this Agreement secret and confidential, except that Welty may disclose this Agreement as required by law, and (a) to her
immediate family, (b) to her lawyers, tax accountants and other advisors in order to seek advice about its provisions, properly account for and report its effects, (c) to obtain enforcement of any of its provisions, provided anyone to whom
Welty is authorized to disclose this Agreement agrees to be bound by the terms of this Section; and (d) if and to the extent that the Agreement has been publicly disclosed by the Company, and except that the Company may disclose the fact and
terms of this Agreement to the extent required by public reporting obligations. 
 7.4 Cooperation. In the event of any
litigation or investigation to which the Company is a party, Welty agrees to make herself reasonably available to provide information and assistance in meetings, depositions, and other related activities without the requirement of a subpoena. The
Company will pay Welty’s reasonable out of pocket expenses incurred in complying with her obligations under this Section 7.4. Nothing in this paragraph shall operate to prevent any party from testifying truthfully under oath when compelled
to do so by subpoena or other legal process. 
 7.5 Consulting Duties. Welty agrees that during the Severance Period, she
will serve as a consultant to and as reasonably requested by the Company in writing with respect to such matters as may be mutually agreed upon by Welty and the Company. Notwithstanding the foregoing, Welty’s services as a consultant shall not
exceed the regulatory threshold under Treas. Reg. 1.409A-1(h)(1)(ii) so as to preclude Welty from qualifying for the presumption that she has separated from service from the Company. 

  
 Page 3 - SEPARATION AGREEMENT
AND RELEASE 

 7.6 Noncompliance Remedy. If Welty is determined by a court of competent jurisdiction
to have materially breached any of the provisions of this Section 7, the Company may recover the severance benefits paid to Welty pursuant to Section 2. The Company agrees that such recovery shall be its exclusive remedy for such breach,
except as set forth in Section 8 below. 
 8. Consent to Injunction. Welty agrees that her violation of
Section 7.2 shall constitute a breach of this Agreement that will cause irreparable injury to the Company, and that monetary damages alone would not adequately compensate the Company for the harm suffered. Welty agrees that the Company shall be
entitled to injunctive relief to enjoin any breach or threatened breach of Section 7.2, in addition to its remedy under Section 7.6. 
 9. Disparagement. Neither party shall make any malicious, disparaging or false remarks about the other, or their respective, officers, directors, employees, heirs or assigns. The parties further
agree to refrain from making any false negative statements regarding the other to any third parties or any statements which could be construed as having or causing a diminishing effect on the other’s reputation, goodwill or business. For the
purpose of this paragraph, the “Company” shall mean the management and Board of Directors of Northwest Pipe Company. Notwithstanding the foregoing, nothing in this paragraph shall operate to prevent any party from testifying truthfully
under oath when compelled to do so by subpoena or other legal process. 
 10. No Admission of Liability. Welty and the
Company agree that nothing in this Separation Agreement and Release, its contents, and any payments made under it, will be construed as an admission of liability on the part of Welty or the Company. 

11. Governing Law, Forum and Attorney Fees. This Agreement shall be interpreted and enforced in accordance with the laws of the
State of Washington, except to the extent preempted by federal law, without regard to conflict of law principles. The exclusive jurisdiction for any action to interpret or enforce this Agreement shall be the State of Washington. The Company agrees
to pay Welty’s attorneys fees incurred in the negotiation and preparation of this Agreement, subject to Welty providing the Company with a copy of her attorneys’ invoices (redacted to protect attorney-client privileged information), and
provided that such attorneys fees do not exceed $10,000. 
 This Agreement is intended to comply with the requirements of Section 409A of
the Internal Revenue Code of 1986, as amended (the “Code”) and the Treasury Regulations and other regulatory guidance promulgated thereunder such that amounts payable to Welty hereunder are exempt from taxation under Code section
409A(a)(1). The provisions of this Agreement shall be construed and interpreted in a manner that is consistent with such intent. For purposes of applying Code section 409A to this Agreement, each separately identified amount to which Welty is
entitled under this Agreement shall be treated as a separate payment. Moreover, to the extent permissible under Code section 409A, any series of installment payments under this Agreement shall be treated as a right to a series of separate payments.

  
 Page 4 - SEPARATION AGREEMENT
AND RELEASE 

 12. Successors and Assigns. This Agreement shall be binding upon Welty’s heirs,
executors, administrators and other legal representatives and may be assigned and enforced by the Company, its successors and assigns. This Agreement shall be binding upon the Company’s successors and assigns and may be enforced by Welty and
her heirs, executors and other legal representatives. 
 13. Severability. The provisions of this Agreement are
severable. If any provision of this Agreement or its application is held invalid, it shall be modified as necessary to render it valid and enforceable. If any provision of this Agreement or its application is held invalid and cannot be modified to
render it valid and enforceable, the invalidity shall not affect other obligations, provisions, or applications of this Agreement which can be given effect without the invalid provisions or applications. 

14. Waiver. The failure of either party to demand strict performance of any provision of this Agreement shall not constitute a
waiver of any provision, term, covenant, or condition of this Agreement or of the right to demand strict performance in the future. 
 15. Section Headings. The section headings contained herein are for reference purposes only and will not in any way affect the meaning or interpretation of this Agreement. 

16. Entire Agreement. Except as otherwise provided in this section, this Agreement constitutes the entire agreement between the
parties and supersedes all prior or contemporaneous oral or written understandings, statements, representations or promises with respect to its subject matter. Welty remains bound by the terms of any and all prior agreements with the Company
pertaining to confidential information, non-competition, non-solicitation and assignment of inventions. The Company remains bound by any indemnity agreements or directors and officers insurance agreements covering Welty during her employment, as
well as by the Stock Agreements. This Agreement was the subject of negotiation between the parties and, therefore, the parties agree that the rule of construction requiring that the agreement be construed against the drafter shall not apply to the
interpretation of this Agreement. 
 This Agreement is not effective until it is signed by both parties.
