set forth on Schedule I hereto under the heading “2013 Revolving Credit Commitment”, on the same terms as in existence prior to the December 2012 Extension Amendment Effective Date; and 

(c) it is agreed that this Amendment shall be deemed to be an “Extension Amendment”, the December 2012 Extension
Amendment Effective Date shall be deemed to be the Extension Date related to this Amendment, the 2013 Revolving Credit Commitments shall continue to be deemed to be “Existing Revolving Credit Commitments”, the related 2013 Revolving Credit
Loans under the 2013 Revolving Credit Commitments shall continue to be deemed to be “Existing Revolving Credit Loans”, the 2016 Revolving Credit Commitments (including those resulting from the extension pursuant to this Amendment) shall

(d) As used herein, “2016 Revolving Credit Commitment Reclassified Amount” shall mean, with respect to
any Lender that submits to the Administrative Agent a signature page to this Amendment offering to extend and reclassify all or a portion of such Lender’s 2013 Revolving Credit Commitment to a 2016 Revolving Credit Commitment at or prior to the
Extension Deadline (each such Lender, a “Submitting 2013 Revolving Credit Lender”), the amount of such 2013 Revolving Credit Commitment submitted for extension and reclassification by such Lender as set forth on its signature page
to this Amendment; and 
 (e) On and after the date of delivery of a signature page by any Submitting 2013
Revolving Credit Lender until the December 2012 Extension Amendment Effective Date, 2013 Revolving Credit Commitments comprising the 2016 Revolving Credit Commitment Reclassified Amount of each Lender shall continue to be subject to the offer to
extend and reclassify made on the date of such signature page’s delivery, notwithstanding any later transfer and/or assignment of all or a portion of such 2016 Revolving Credit Commitment Reclassified Amount to another Transferee prior to the
December 2012 Extension Amendment Effective Date.

as of the December 2012 Extension Amendment Effective Date, hereby amended to delete the stricken text (indicated textually in the same manner as the following example: stricken text) and to add the double-underlined text (indicated
textually in the same manner as the following example: double-underlined text) as set forth in the pages of the Credit Agreement attached as Annex I hereto, except that each Schedule or Exhibit to the Credit Agreement shall remain in

Commitment Extension Effective Date and the 2011 Term/Deposit L/C Extension Effective Date. 
 Section 3
Representations and Warranties, No Default. The Borrower represents and warrants to the Lenders as of the December 2012 Extension Amendment Effective Date: 
 (a) The execution and delivery of this Amendment by the Credit Parties has been duly authorized, and each of this Amendment and each other Credit Document to which any Credit Party is a party (as such
Credit Documents may be amended hereby) constitutes the legal, valid and binding obligation of such Credit Party enforceable in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization and
other similar laws relating to or affecting creditors’ rights generally and general principles of equity (whether considered in a proceeding in equity or law). 

  
 -3-

 (b) The execution, delivery and performance by the Credit Parties of this Amendment will not
(a) contravene any applicable provision of any material Applicable Law (including material Environmental Laws), (b) result in any breach of any of the terms, covenants, conditions or provisions of, or constitute a default under, or result
in the creation or imposition of (or the obligation to create or impose) any Lien upon any of the property or assets of US Holdings, the Borrower or any Restricted Subsidiary (other than Liens created under the Credit Documents or Liens subject to
the Intercreditor Agreement) pursuant to the terms of any material indenture (including the Existing Notes Indentures), loan agreement, lease agreement, mortgage, deed of trust or other material agreement or instrument to which US Holdings, the
Borrower or any Restricted Subsidiary is a party or by which it or any of its property or assets is bound other than any such breach, default or Lien that could not reasonably be expected to result in a Material Adverse Effect, or (c) violate
any provision of the Organizational Documents of US Holdings, the Borrower or any Restricted Subsidiary. 
 (c) The
representations and warranties set forth in the Credit Agreement and in the other Credit Documents are true and correct in all material respects with the same effect as if made on the December 2012 Extension Amendment Effective Date, except to the
extent such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects as of such earlier date. 

(d) At the time of and after giving effect to this Amendment, no Default or Event of Default has occurred and is continuing. 

(e) The execution, delivery and performance by the Credit Parties of this Amendment will not contravene or result in a breach of any of
the terms, covenants, conditions or provisions of, or constitute a default under, any Credit Document and after giving effect to this Amendment, the 2013 Revolving Credit Commitments and related 2013 Revolving Credit Loans extended and reclassified
hereby shall be Obligations under the Credit Agreement, secured by all liens created under the Credit Documents (which liens shall continue to be perfected and secured immediately after giving effect to this Amendment) and having the benefit of all
guarantees made pursuant to the Guarantee, in each case to the same extent as the Obligations in respect of the 2013 Revolving Credit Commitments as in effect immediately prior to the effectiveness of this Amendment. Without limiting the foregoing,
for purposes of clarity, the 2013 Revolving Credit Commitments and related 2013 Revolving Credit Loans extended and reclassified hereby shall for all purposes be pari passu with, and entitled to all benefits, rights, and remedies of, the existing
2016 Revolving Credit Commitments and 2016 Revolving Credit Loans. 
 (f) Each entity that is required to be a Guarantor under
the Credit Agreement has executed this Amendment. 
 Section 4 Conditions to Effectiveness of December 2012 Extension
Amendment Effective Date. 
 (a) This Amendment, including the provisions of Section 1 and the amendments set forth
in Section 2 shall become effective on the date (the “December 2012 Extension Amendment Effective Date”) on which each of the following conditions are satisfied 

  
 -4-

 
or waived by the applicable party (provided that Annex I hereto may be modified to make ministerial changes to reflect the completion of the 2012 Revolving Credit Extension in a manner as
reasonably agreed between the Borrower and the Administrative Agent): 
 (i) the Administrative Agent shall have
received executed signature pages to this Amendment from US Holdings, the Borrower, each other Credit Party that is party to a Credit Document and Citibank, N.A., in its capacity as Administrative Agent, Collateral Agent and Swingline Lender;

 (ii) payment by the Borrower to the Administrative Agent, for the account of each 2013 Revolving Lender that
has returned an executed signature page to this Amendment to the Administrative Agent at or prior to 5:00 p.m., New York City time on January 4, 2013 (the “Extension Deadline”) agreeing to extend and reclassify an amount of its
2013 Revolving Credit Commitment, an extension fee (the “Extension Fee”), which fee shall be paid through the incurrence of Incremental Term Loans deemed to have been made by such Lender to the Borrower, having the terms and
conditions and the principal amount set forth in the Incremental Amendment No. 1 attached to this Amendment as Exhibit A, with each such 2013 Revolving Lender receiving $0.52641 in principal amount of Incremental Loans for each $1.00 of its
2013 Revolving Credit Commitments extended and reclassified pursuant hereto; provided that, to the extent the aggregate amount of Extension Fees that would have been required to be paid pursuant to this clause (ii) would have resulted in
the deemed incurrence of an aggregate principal amount of Incremental Term Loans pursuant to the Incremental Amendment that is not in an amount that is a whole multiple of $1,000,000, then the aggregate principal amount of such Incremental Term
Loans deemed to have been made by such Lenders shall be rounded up to the nearest whole multiple of $1,000,000, with such increase allocated pro rata among the Submitting 2013 Revolving Credit Lenders based on each such Lender’s 2016 Revolving
Credit Commitment Reclassified Amount (it being understood that the Borrower shall have no liability to pay the Extension Fee if the December 2012 Extension Amendment Effective Date does not occur); 

(iii) the Administrative Agent shall have received from the Borrower a certificate of an Authorized Officer of the
Borrower (A) to the effect that representations and warranties set forth in Section 3 hereof are true and correct on and as of the December 2012 Extension Amendment Effective Date and (B) in connection with the Incremental Term Loans
to be deemed made, setting forth calculations (in reasonable detail) demonstrating compliance with the covenant set forth in Section 10.9 of the Credit Agreement determined on a Pro Forma Basis as of the date of the making of such Incremental
Term Loans and as of the last day of the most recent Test Period, in each case as if such Incremental Term Loans had been outstanding on the last day of such Test Period for testing compliance therewith; 

(iv) the Administrative Agent shall have received (A) a certificate of an Authorized Officer of each Credit Party
attaching (x) a copy of the resolutions, in form and substance reasonably satisfactory to the Administrative Agent, of the board of directors, other managers or general partner of each Credit Party (or a duly authorized committee thereof)

Incremental Amendment, (y) true and complete copies of the Organizational Documents of the Credit Parties (which may be incorporated by reference into such certificate to the extent the same are publicly available on the SEC’s website at

(B) signature and incumbency certificates of each officer executing this Amendment and such Incremental Amendment or any other document delivered in connection herewith or therewith on behalf of each Credit Party and (C) good standing
certificates for each Credit Party for each jurisdiction in which such Credit Party is organized;

promptly after the occurrence thereof, and shall deliver to the Borrower a completed copy of Schedule I to this Amendment reflecting the 2013 Revolving Credit Commitment of each 2013 Revolving Credit Lender and 2016 Revolving Credit Commitment of
each 2016 Revolving Credit Lender, in each case after giving effect to the December 2012 Extension Amendment Effective Date. 

Section 5 Post-Closing Undertakings. Within the applicable time periods specified in Schedule II hereto, the Credit
Parties agree to comply with the provisions set forth in said Schedule II. 
 Section 6 Counterparts. This
Amendment may be executed in any number of counterparts and by different parties hereto on separate counterparts, each of which when so executed and delivered shall be deemed to be an original, but all of which when taken together shall constitute a
single instrument. Delivery of an executed counterpart of a signature page of this Amendment by facsimile or other electronic transmission (i.e. a “PDF” or “TIF”) shall be effective as delivery of a manually executed counterpart
hereof. 
 Section 7 Applicable Law. THIS AMENDMENT SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK. 
 Section 8 Headings. The headings of this Amendment are for

given as provided in the Credit Agreement or, as the case may be, the Guarantee.

any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other provision of either such agreement or any other Credit Document, and each Credit Party acknowledges and agrees that each of the Credit
Documents to which it is a party or otherwise bound shall continue in full force and effect and that all of its obligations thereunder shall be valid and enforceable and shall not be impaired or limited by the execution or effectiveness of this
Amendment. Each and every term, condition, obligation, covenant and agreement contained in the Credit Agreement or any other Credit Document is hereby ratified and re-affirmed in all respects and shall continue in full force and effect. Each Credit
Party reaffirms its obligations under the Credit Documents to which it is party and the validity of the Liens granted by it pursuant to the Security Documents. From and after the effective date of this Amendment, all references to the Credit
Agreement in any Credit Document shall, unless expressly provided otherwise, refer to the Credit Agreement as amended by this Amendment. In entering into this Amendment, each Lender has undertaken its own analysis and has not relied on any other
Lender in making its decision to enter into this Amendment. This Amendment shall constitute a Credit Document.

 Schedule I to December 2012 Extension Amendment 

 Schedule II 
 Post-Closing Undertakings 
 With respect to any Mortgaged Property, within 120 days, unless
extended by the Collateral Agent in its sole discretion, the Borrower will deliver, or cause to be delivered, to the Collateral Agent (i) a Mortgage with respect to each Mortgaged Property, executed by a duly authorized officer of each obligor
party thereto, (ii) title insurance of the type described in, and the other items required by, Section 6.2(f)(iii) of the Credit Agreement with respect to each such Mortgaged Property in an amount acceptable to the Collateral Agent in its
sole and absolute discretion, (iii) to the extent deemed necessary or advisable by the Collateral Agent in its reasonable discretion, for each Mortgaged Property consisting of a nuclear or coal-fired power plant, a new Survey or a copy of the
most recent Survey together with an affidavit stating that there has been no change as long as the title company agrees to remove all standard survey exceptions and issue customary survey-related endorsements; provided that, notwithstanding
the foregoing, with respect to the oil, gas and other mineral interests described in item 4 under part B of Schedule 1.1(c) of the Credit Agreement, the Mortgages will describe the mortgaged mineral interests in the manner customary for the
mortgaging of similar mineral interests in similar transactions and there will be no title insurance or Surveys in connection with such Mortgaged Properties to the extent not previously required, (iv) legal opinions with respect to the
Mortgages covering such matters as the Administrative Agent may reasonably request (including, without limitation, any corporate related opinions) and otherwise reasonably satisfactory to the Administrative Agent, and (v) to the extent deemed
necessary or advisable in the Collateral Agent’s reasonable discretion, an agreement with the holders of any existing liens and/or mortgages regarding priority of the Liens of such mortgages and the Mortgage for each Mortgaged Property, which
agreement shall include customary subordination language, in each case in form and substance acceptable to the Collateral Agent in its sole and absolute discretion. The Borrower, within 30 days, unless extended by the Collateral Agent in its
reasonable discretion, will deliver, or cause to be delivered, (i) a completed Federal Emergency Management Agency Standard Flood Determination with respect to each Mortgaged Property, in each case in form and substance reasonably satisfactory
to the Collateral Agent, (ii) evidence of flood insurance with respect to each Mortgaged Property, to the extent and in amounts required by Applicable Laws, in each case in form and substance reasonably satisfactory to the Collateral Agent, and
(iii) revised insurance certificates of the type required to be delivered pursuant to Section 6.15 of the Credit Agreement to reflect that such insurance covers all Mortgaged Property and designating the amount of insurance applicable to

Borrower, which Swingline Loans (i) shall be ABR Loans, (ii) shall have the benefit of the provisions of Section 2.1(e)(ii), (iii) shall not exceed at any time outstanding the Swingline Commitment, (iv) shall not,
after giving effect thereto and to the application of the proceeds thereof, result at any time in the aggregate amount of the Lenders’ Revolving Credit Exposures at such time exceeding the Total Revolving Credit Commitment then in effect and
(v) may be repaid and reborrowed in accordance with the provisions hereof. The Swingline Lender shall not make any Swingline Loan after receiving a written notice from the Borrower or the Required Lenders stating that a Default or Event of
Default exists and is continuing until such time as the Swingline Lender shall have received written notice (i) of rescission of all such notices from the party or parties originally delivering such notice or (ii) of the waiver of such
Default or Event of Default in accordance with the provisions of Section 13.1 or (iii) that such Default or Event of Default is no longer continuing. 
 (ii) On any Business Day, the Swingline Lender may, in its sole discretion, give notice to the Revolving Credit Lenders, with a copy to the Borrower and the Administrative Agent, that all then-outstanding
Swingline Loans shall be funded with a Borrowing of Revolving Credit Loans, in 

  
 -93-

 
which case Revolving Credit Loans constituting ABR Loans (each such Borrowing, a “Mandatory Borrowing”) shall be made on the immediately succeeding Business Day by all Revolving
Credit Lenders pro rata based on each such Lender’s Revolving Credit Commitment Percentage (regardless of the Class of Revolving Credit Commitment held by such Lenders), and the proceeds thereof shall be applied directly to the
Swingline Lender to repay the Swingline Lender for such outstanding Swingline Loans. Each Revolving Credit Lender hereby irrevocably agrees to make such Revolving Credit Loans upon one Business Day’s notice pursuant to each Mandatory Borrowing
in the amount and in the manner specified in the preceding sentence and on the date specified to it in writing by the Swingline Lender notwithstanding (i) that the amount of the Mandatory Borrowing may not comply with the minimum amount for
each Borrowing specified in Section 2.2, (ii) whether any conditions specified in Section 7 are then satisfied, (iii) whether a Default or an Event of Default has occurred and is continuing, (iv) the date of
such Mandatory Borrowing or (v) any reduction in the Total Revolving Credit Commitment after any such Swingline Loans were made. In the event that, in the sole judgment of the Swingline Lender, any Mandatory Borrowing cannot for any reason be
made on the date otherwise required above (including as a result of the commencement of a proceeding under the Bankruptcy Code in respect of the Borrower), each Revolving Credit Lender hereby agrees that it shall forthwith purchase from the
Swingline Lender (without recourse or warranty) such participation of the outstanding Swingline Loans as shall be necessary to cause each such Lender to share in such Swingline Loans ratably based upon their respective Revolving Credit Commitment
Percentages (regardless of the Class of Revolving Credit Commitments held by such Lender); provided that all principal and interest payable on such Swingline Loans shall be for the account of the Swingline Lender until the date the respective
participation is purchased and, to the extent attributable to the purchased participation, shall be payable to such Lender purchasing same from and after such date of purchase. On and after the 2011 Revolving Credit Commitment Extension Effective
Date until the Original Swingline Maturity Date, participations in Swingline Loans shall be allocated in accordance with the aggregate Revolving Credit Commitment (including both 2013 Revolving Credit Commitments and 2016 Revolving Credit
Commitments). Notwithstanding anything contained in this Agreement to the contrary, if the 2011 Revolving Credit Commitment Extension Effective Date occurred, on the Original Swingline Maturity Date, the interests and participations
of the 2013 Revolving Lenders in the Swingline Loans (if any) outstanding as at such day shall automatically terminate at the close of business on such date and such interests and participations in outstanding Swingline Loans shall thereupon
automatically and without further action be re-allocated to the extent necessary such that the interests and participations in such Swingline Loans shall be held by the 2016 Revolving Credit Lenders ratably in proportion to their respective 2016
Revolving Credit Commitments. If the reallocations described in the previous sentence cannot, or can only partially, be effected as a result of the limitations set forth herein, the Borrower shall, on the Original Swingline Maturity Date, prepay
Swingline Loans in an amount necessary such that after giving effect to such prepayment the reallocations described in the previous sentence can be fully effected and the sum of the principal amount of all then outstanding Swingline Loans plus
(without duplication) the 2016 Revolving Credit Exposure of all 2016 Revolving Credit Lenders does not exceed the Total 2016 Revolving Commitment. 
 (iii) Resignation of Swingline Lender. The Swingline Lender may resign as Swingline Lender upon 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrower. If the
Swingline Lender shall resign, then the Borrower may appoint from among the Lenders a successor Swingline Lender, whereupon such successor Swingline Lender shall succeed to the rights, powers and duties of the replaced or resigning Swingline Lender
under this Agreement and the other Credit Documents, and the term “Swingline Lender” shall mean such successor or such new Swingline Lender effective upon such appointment. The acceptance of any appointment as a Swingline Lender hereunder
shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the Borrower and the Administrative Agent. If the Swingline Lender resigns as Swingline Lender, it shall retain all rights of the Swingline Lender provided
for hereunder with respect to Swingline Loans made by it and outstanding as of the effective date of such resignation, including the right to require the Lenders to make Revolving Credit Loans and fund risk participations in outstanding Swingline
Loans.

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

below; provided that all Swingline Loans shall be made available in the full amount thereof by the Swingline Lender no later than 3:30 p.m. (New York City time) on the date requested; provided, further, that for the

Drawings under Revolving Letters of Credit) make available to the Borrower, by depositing to an account designated by the Borrower to the Administrative Agent the aggregate of the amounts so made available in Dollars. Unless the Administrative Agent
shall have been notified by any Lender prior to the date of any such Borrowing that such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative
Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so)
make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender and the Administrative Agent has made available such amount to the Borrower, the
Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor the Administrative Agent shall
promptly notify the Borrower and the Borrower shall immediately pay such corresponding amount to the Administrative Agent in Dollars. The Administrative 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 Administrative Agent to the Borrower to the date such corresponding amount is recovered by the Administrative 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 Loans of the applicable Class.

 (c) Nothing in this Section 2.4 shall be deemed to relieve any 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).

 2.6. Conversions and Continuations.

 (a) Subject to the penultimate sentence of this clause (a), (x) the Borrower shall have the option on any Business

into a Borrowing or Borrowings of another Type and (y) the Borrower shall have the option on any Business Day to continue the outstanding principal amount of any LIBOR Loans as LIBOR Loans for an additional Interest Period; provided that
(i) no partial conversion of LIBOR Loans shall reduce the outstanding principal amount of LIBOR Loans made pursuant to a single Borrowing to less than the Minimum Borrowing Amount, (ii) ABR Loans may not be converted into LIBOR Loans if a
Default or Event of Default is in existence on the date of the conversion and the Administrative Agent has or the Required Lenders have determined in 

  
 -102-

 its or their sole discretion not to permit such conversion, (iii) LIBOR Loans may not be continued as
LIBOR Loans for an additional Interest Period if a Default or Event of Default is in existence on the date of the proposed continuation and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to
permit such continuation, (iv) Borrowings resulting from conversions pursuant to this Section 2.6 shall be limited in number as provided in Section 2.2 and (v) Swingline Loans may not be converted to LIBOR Loans.
Each such conversion or 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. Subject to Section 2.1(d), 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 without regard to the Class of Revolving Credit Commitments held by such Lender. 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. 
 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. 

  
 -103-

 (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. 
 (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 

  
 -104-

 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) prior to the 2014 Deposit L/C Loan Maturity Date and within 20 Business Days, following the 2014 Deposit L/C Loan Maturity Date, (i) if the Shortfall Amount at the end of such
month (or at the 2014 Deposit L/C Loan Maturity Date, as applicable) 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 (A) in no event shall the Borrower be obligated to make Shortfall Payments to the Administrative Agent that, in the aggregate, exceed the
greater of (x) the aggregate amount of Shortfall Payments made by the Administrative Agent to the Borrower from the Closing Date through any such date of determination and (y) the Upside Amount as of the date of such determination (each
such payment made pursuant to this clause (y) in excess of the amount in clause (x), an “Upside Amount Payment”) and (B) for the avoidance of doubt, (1) the Administrative Agent shall have no obligation to make
Shortfall Payments to the Borrower with respect to amounts accrued (or that would have accrued) after the 2014 Deposit L/C Loan Maturity Date and (2) the Borrower shall have no obligation to make Shortfall Payments to the Administrative Agent
with respect to amounts accrued (or that would have accrued) after the 2014 Deposit L/C Loan Maturity Date. 
 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; 

  
 -105-

 (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; 
 (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 Closing Date 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 Closing Date that materially and adversely affects the interbank LIBOR market; 
 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 

  
 -106-

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

  
 -107-

 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;
provided that on or after the 2011 Revolving Credit Commitment Extension Effective Date, increases shall be of the 2016 Revolving Credit Commitments or any other Extended Revolving Credit Commitment (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 

  
 -108-

 
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. 
 (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 $750,000,000 minus the aggregate principal amount of Permitted Other Debt incurred under Section 10.1(y)(iii) (the “Incremental Limit”). 

(c) The Incremental Term Loans (i) shall rank pari passu in right of payment and of security with the Revolving Credit Loans, all
other Term Loans, the Posting Advances and the Deposit L/C Loans, (ii) shall not mature earlier than the Latest Maturity Date, (iii) shall have interest rates, interest margins, rate floors, fees, funding discounts, premiums and
amortization schedules determined by the Borrower and the lenders thereof and (iv) may have terms and conditions different from those of the other 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 Term Loans, the Posting Advances and all other Deposit L/C Loans, (ii) shall not mature earlier than the
Latest Maturity Date, (iii) shall have interest rates, interest margins, rate floors, fees, funding discounts, premiums and amortization schedules determined by the Borrower and the lenders thereof and (iv) may have terms and conditions
different from those of the other Deposit L/C Loans; provided that, except with respect to the differences set forth in clauses (ii) and (iii) above, any differences must be reasonably acceptable to the Administrative
Agent. 
 (e) Each Incremental Posting Facility shall rank pari passu in right of payment and of security with the Revolving
Credit Loans, the Term Loans, all other Posting Advances and the Deposit L/C Loans. 
 (f) Each notice from the Borrower
pursuant to this Section 2.14 shall set forth the requested amount and proposed terms of the relevant Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving Commitment Increases or Incremental Posting Facilities.
Incremental Term Loans and Incremental Deposit L/C Loans may be made, and Incremental Revolving Commitment Increases and Incremental Posting Facilities may be provided, by any existing Lender (it being understood that (i) no existing Lender
will have an obligation to make a portion of any Incremental Term Loan, Incremental Deposit L/C Loan or any Incremental Posting Facility, (ii) no existing Lender with a Revolving Credit Commitment will have any obligation to provide a portion
of any Incremental Revolving Commitment Increase and (iii) the Borrower shall have no obligation to offer any existing Lender the opportunity to provide any such Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving
Commitment Increases (including pursuant to New Revolving Credit Commitments) or Incremental Posting Facilities) or by any 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. 

  
 -109-

 (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 thereof (each an “Incremental Facility Closing Date”) of the conditions in Section 7.1 and such other conditions as the
parties thereto shall agree. The Borrower may use the proceeds of the Incremental Term Loans, Incremental Deposit L/C Loans, Incremental Revolving Commitment Increases and Incremental Posting Facilities for any purpose not prohibited by this
Agreement. 
 (h) (i) No Lender shall be obligated to provide any Incremental Term Loans, Incremental Deposit L/C Loans,
Incremental Revolving Commitment Increases or Incremental Posting Facilities, unless it so agrees and the Borrower shall not be obligated to offer any existing Lender the opportunity to provide any Incremental Term Loans, Incremental Deposit L/C
Loans, Incremental Revolving Credit Increases or Incremental Posting Facilities. Upon each increase in the Revolving Credit Commitments or, after the 2011 Revolving Credit Commitment Extension Effective Date, the 2016 Revolving Credit Commitments or
any other Extended Revolving Credit Commitment (other than pursuant to clause (ii) below) pursuant to this Section, each Lender with a Revolving Credit Commitment immediately prior to such increase will automatically and without further act be
deemed to have assigned to each Lender providing a portion of the Incremental Revolving Commitment Increase (each an “Incremental Revolving Commitment Increase Lender”) in respect of such increase, and each such Incremental
Revolving Commitment Increase Lender will automatically and without further act be deemed to have assumed, a portion of such Lender’s participations hereunder in outstanding Revolving Letters of Credit and Swingline Loans such that, after
giving effect to each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding (i) participations hereunder in Revolving Letters of Credit and (ii) participations hereunder in Swingline Loans
held by each Lender with a Revolving Credit Commitment (including each such Incremental Revolving Commitment Increase Lender) will equal the percentage of the aggregate Revolving Credit Commitments of all Lenders represented by such Lender’s
Revolving Credit Commitment. If, on the date of such increase, there are any Revolving Credit Loans outstanding, such Revolving Credit Loans shall on or prior to the effectiveness of such Incremental Revolving Commitment Increase be prepaid from the
proceeds of additional Revolving Credit Loans made 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. 

  
 -110-

 (ii) At the option of the Borrower and the Incremental Lenders providing such Incremental
Revolving Commitment Increases, any Incremental Revolving Commitment Increases may be in the form of one or more separate classes of revolving credit commitments (the “New Revolving Credit Commitments”) which shall constitute a
separate Class of Commitments from the Revolving Credit Commitments, any other Extended Revolving Credit Commitments and/or any other New Revolving Credit Commitments (each such separate Class of New Revolving Credit Commitments, a “New
Revolving Credit Series” and each Loan thereunder, a “New Revolving Credit Loan”) and the related Loans shall constitute a separate Class of Loans from the Revolving Credit Loans, any other Extended Revolving Credit Loans
and/or any other New Revolving Credit Loans (it being understood that New Revolving Credit Commitments of a single New Revolving Credit Series may be established on more than one date); provided that: 

(A) the aggregate amount of New Revolving Credit Commitments in effect at any time, when aggregated with the aggregate
amount of Revolving Credit Commitments and any other Extended Revolving Credit Commitments at such time, shall not exceed the sum of (x) $2,700,000,000 less all 2011 Revolving Credit Commitment Termination Amounts and (y) the
remainder, if positive, of (A) $750,000,000 minus (B) the aggregate amount of Incremental Term Loans and Incremental Deposit L/C Loans established on or prior to such date minus (C) the aggregate amount of Permitted Other Debt
previously established in reliance of Section 10.1(y)(iii); 
 (B) Each tranche of New Revolving
Credit Commitments shall be in an aggregate principal amount of not less than $50,000,000 (provided that such amount may be less than $50,000,000 if such amount represents all remaining availability under the limit set forth in
Section 2.14(b) above). 
 (C) the terms of such New Revolving Credit Commitments, except for
(w) the tenor of the New Revolving Credit Commitments (which shall have a scheduled expiration date no earlier than the Revolving Credit Maturity Date), (x) the size of any swingline loan and/or letter of credit subfacilities under such
New Revolving Credit Commitments, (y) the applicable interest rates, interest margins, rate floors, premiums, funding discounts and fees payable with respect to such New Revolving Credit Commitments and (z) the borrowing, repayment and
termination of Commitment procedures (in each case which shall be as specified in the applicable Incremental Amendment), shall be similar to the terms of the Revolving Credit Commitments and any other Extended Revolving Credit Commitments (unless
otherwise consented to by the Administrative Agent); and 
 (D) in connection with the establishment of any New
Revolving Credit Commitments that will include swingline loan and/or letter of credit subfacilities, any amendment to this Agreement pursuant to this Section 2.14(h)(ii) may include provisions relating to swingline loans and/or letters
of credit, as applicable, issued thereunder, which issuances shall be on terms similar (except for the overall size of such subfacilities and the identity of the swingline lender and letter of credit issuer, as applicable, and borrowing, repayment
and termination of commitment procedures, in each case which shall be specified in the applicable Incremental Amendment) to the terms relating to Swingline Loans and Letters of Credit with respect to the Revolving Credit Commitments or otherwise
reasonably acceptable to the Administrative Agent and any applicable swingline lender or letter of credit issuer thereunder. 

  
 -111-

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

  
 -112-

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

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

  
 -113-

 provided in the applicable Extension Amendment, (y) subject to the provisions set forth in Sections
5.1 and 5.2, the Extended Deposit L/C Loans may have optional prepayment terms (including call protection and prepayment premiums) and mandatory prepayment terms as may be agreed between the Borrower and the Lender thereof and
(z) the Extension Amendment may provide for other covenants and terms that apply solely to any period after the Latest Maturity Date, provided that the principal amount of the Extended Deposit L/C Loans shall not exceed the principal
amount of the Existing Deposit L/C Loans being extended. No Lender shall have any obligation to agree to have any of its Deposit L/C Loans of any Existing Deposit L/C Loan Class exchanged into Extended Deposit L/C Loans pursuant to any Deposit L/C
Loan Extension Request. Any Extended Deposit L/C Loans of any Extension Series shall constitute a separate Class of Deposit L/C Loans from the Existing Deposit L/C Loan Class of Deposit L/C Loans from which they were extended. Notwithstanding
anything to the contrary contained in this Section 2.15(a)(iii), the applicable Extension Amendment may provide that the Deposit L/C Termination Date may be extended and the related obligations to make Deposit Letters of Credit may be
continued so long as the applicable Deposit Letter of Credit Issuer has consented to such extensions (it being understood that no consent of any other Lender shall be required in connection with any such extension). 

(b) The Borrower shall provide the applicable Extension Request at least five (5) Business Days (or such shorter period as the
Administrative Agent may determine in its discretion) prior to the date on which Lenders under the Existing Class are requested to respond, and shall agree to such procedures, if any, as may be established by, or acceptable to, the Administrative
Agent in each case acting reasonably to accomplish the purposes of this Section 2.15 (it being understood that the offer and allocation procedures for each Extension Series shall be substantially similar to those used for the offer and
allocation of loans as provided in Amendment No. 2). Any Lender (an “Extending Lender”) wishing to have all or a portion of its Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New Revolving Credit Commitments or
Extended Revolving Credit Commitments of the Existing Class subject to such Extension Request exchanged into Extended Loans/Commitments shall notify the Administrative Agent (an “Extension Election”) on or prior to the date
specified in such Extension Request of the amount of its Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class which it has elected to exchange
into Extended Loans/Commitments (subject to any minimum denomination requirements imposed by the Administrative Agent). In the event that the aggregate amount of Term Loans, Deposit L/C Loans, Revolving Credit Commitments, New Revolving Credit
Commitments or Extended Revolving Credit Commitments of the Existing Class subject to Extension Elections exceeds the amount of Extended Loans/Commitments requested pursuant to the Extension Request, Term Loans, Deposit L/C Loans, Revolving Credit
Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments subject to Extension Elections shall be converted to Extended Loans/Commitments as provided for in the applicable Extension Amendment. Notwithstanding the
conversion of any Existing Revolving Credit Commitment (other than a New Revolving Credit Commitment) into an Extended Revolving Credit Commitment, such Extended Revolving Credit Commitment shall be treated identically to all other Old Revolving
Credit Commitments for purposes of the obligations of a Revolving Credit Lender in respect of Swingline Loans under Section 2.1(e) and Revolving Letters of Credit under Article 3, except that the applicable Extension Amendment may
provide that the Swingline Maturity Date and/or the Revolving L/C Maturity Date may be extended and the related obligations to make Swingline Loans and issue Revolving Letters of Credit may be continued so long as the applicable Swingline Lender
and/or the applicable Revolving Letter of Credit Issuer, as applicable, have consented to such extensions (it being understood that no consent of any other Lender shall be required in connection with any such extension). Notwithstanding the
conversion of any Existing Revolving Credit Commitment that is a New Revolving Credit Commitment (or any previously extended New Revolving Credit Commitment) into an Extended Revolving Credit Commitment, such Extended Revolving Credit Commitment
shall be treated identically to all other Old Revolving Credit Commitments for purposes of the obligations of a Lender in respect of swingline loans and letters of 

  
 -114-

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

  
 -115-

 such Lender on such date, and the Extended Term Loans shall be established as a separate Class of Term Loans
(together with any other Extended Term Loans so established on such date), (II) in the case of the existing Deposit L/C Loans of each Extending Lender, the aggregate principal amount of such existing Deposit L/C Loans shall be deemed reduced by an
amount equal to the aggregate principal amount of Extended Deposit L/C Loans so exchanged by such Lender on such date, and the Extended Deposit L/C Loans shall be established as a separate Class of Deposit L/C Loans (together with any other Extended
Deposit L/C Loans so established on such date), and (III) in the case of the Specified Existing Revolving Credit Commitments of each Extending Lender, the aggregate principal amount of such Specified Existing Revolving Credit Commitments shall be
deemed reduced by an amount equal to the aggregate principal amount of Extended Revolving Credit Commitments so exchanged by such Lender on such date, and such Extended Revolving Credit Commitments shall be established as a separate Class of
revolving credit commitments from the Specified Existing Revolving Credit Commitments and from any other Existing Revolving Credit Commitments (together with any other Extended Revolving Credit Commitments so established on such date) and
(B) if, on any Extension Date, any Loans of any Extending Lender are outstanding under the applicable Specified Revolving Credit Commitments, such Loans (and any related participations) shall be deemed to be allocated as Extended Revolving
Credit Loans (and related participations) and Existing Revolving Credit Loans (and related participations) in the same proportion as such Extending Lender’s Specified Revolving Credit Commitments to Extended Revolving Credit Commitments.

 (e) In the event that the Administrative Agent determines in its sole discretion that the allocation of Extended Term Loans
of a given Extension Series, Extended Deposit L/C Loans of a given Extension Series or the Extended Revolving Credit Commitments of a given Extension Series, in each case to a given Lender was incorrectly determined as a result of manifest
administrative error in the receipt and processing of an Extension Election timely submitted by such Lender in accordance with the procedures set forth in the applicable Extension Amendment, then the Administrative Agent, the Borrower and such
affected Lender may (and hereby are authorized to), in their sole discretion and without the consent of any other Lender, enter into an amendment to this Agreement and the other Credit Documents (each, a “Corrective Extension
Amendment”) within 15 days following the effective date of such Extension Amendment, as the case may be, which Corrective Extension Amendment shall (i) provide for the conversion and extension of Term Loans under the Existing Term Loan
Facility, Deposit L/C Loans under the Existing Deposit L/C Loan Facility or Existing Revolving Credit Commitments (and related Revolving Credit Exposure), as the case may be, in such amount as is required to cause such Lender to hold Extended Term
Loans, Extended Deposit L/C Loans or Extended Revolving Credit Commitments (and related Revolving Credit Exposure) of the applicable Extension Series into which such other Term Loans, Deposit L/C Loans or Revolving Credit Commitments or New
Revolving Credit Commitments, as the case may be, were initially converted, as the case may be, in the amount such Lender would have held had such administrative error not occurred and had such Lender received the minimum allocation of the
applicable Loans or Commitments to which it was entitled under the terms of such Extension Amendment, in the absence of such error, (ii) be subject to the satisfaction of such conditions as the Administrative Agent, the Borrower and such Lender
may agree (including conditions of the type required to be satisfied for the effectiveness of an Extension Amendment described in Section 2.15(c)), and (iii) effect such other amendments of the type (with appropriate reference and
nomenclature changes) described in the penultimate sentence of Section 2.15(c). 
 (f) No exchange of Loans or
Commitments pursuant to any Extension Amendment in accordance with this Section 2.15 shall constitute a voluntary or mandatory payment or prepayment for purposes of this Agreement. 

  
 -116-

 2.16. Defaulting Lenders. Notwithstanding any provision of this Agreement to the
contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender: 
 (a) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 4.1(a); 

(b) if any Swingline Exposure or Revolving Letter of Credit Exposure exists at the time a Lender becomes a Defaulting Lender, then
(i) all or any part of such Revolving Letter of Credit Exposure of such Defaulting Lender and such Swingline Exposure of such Defaulting Lender will, subject to the limitation in the first proviso below, automatically be reallocated (effective
on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Revolving Credit Commitment Percentage; provided that (A) each Non-Defaulting Lender’s Revolving
Letter of Credit Exposure plus its Swingline Exposure may not in any event exceed the Revolving Credit Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (B) neither such reallocation nor any payment by a
Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Revolving Letter of Credit Issuers, the Swingline Lender or any other Lender may have against such Defaulting Lender
or cause such Defaulting Lender to be a Non-Defaulting Lender, (ii) to the extent that all or any portion of the Defaulting Lender’s Revolving Letter of Credit Exposure and Swingline Exposure cannot, or can only partially, be so
reallocated to Non-Defaulting Lenders, whether by reason of the first proviso in Section 2.16(b)(i) above or otherwise, the Borrower shall within two Business Days following notice by the Administrative Agent (x) first, prepay such
Swingline Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) and (y) second, Cash Collateralize such Defaulting Lender’s Revolving Letter of Credit Exposure (after giving effect to any partial
reallocation pursuant to clause (i) above), in accordance with the procedures set forth in Section 3.8 for so long as such Revolving Letter of Credit Exposure is outstanding, (iii) if the Borrower Cash Collateralizes any
portion of such Defaulting Lender’s Revolving Letter of Credit Exposure pursuant to the requirements of this Section 2.16(b), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to
Section 4.1(c) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Revolving Letter of Credit Exposure is Cash Collateralized, (iv) if the Revolving Letter of
Credit Exposure of the Non-Defaulting Lenders is reallocated pursuant to the requirements of this Section 2.16(b), then the fees payable to the Lenders pursuant to Section 4.1(c) shall be adjusted in accordance with such
Non-Defaulting Lenders’ Revolving Credit Commitment Percentages and the Borrower shall not be required to pay any fees to the Defaulting Lender pursuant to Section 4.1(c) with respect to such Defaulting Lender’s Revolving
Letter of Credit Exposure during the period that such Defaulting Lender’s Revolving Letter of Credit Exposure is reallocated, or (v) if any Defaulting Lender’s Revolving Letter of Credit Exposure is neither Cash Collateralized nor
reallocated pursuant to the requirements of this Section 2.16(b), then, without prejudice to any rights or remedies of the applicable Revolving Letter of Credit Issuer or any Lender hereunder, all fees payable under
Section 4.1(c) with respect to such Defaulting Lender’s Revolving Letter of Credit Exposure shall be payable to the applicable Revolving Letter of Credit Issuer until such Revolving Letter of Credit Exposure is Cash Collateralized
and/or reallocated; 
 (c) no Revolving Letter of Credit Issuer will be required to issue any new Revolving Letter of Credit or
to amend any outstanding Revolving Letter of Credit to increase the face amount thereof, alter the drawing terms thereunder or extend the expiry date thereof, unless the applicable Revolving Letter of Credit Issuer is reasonably satisfied that any
exposure that would result from the exposure to such Defaulting Lender is eliminated or fully covered by the Revolving Credit Commitments of the Non-Defaulting Lenders or by Cash Collateralization or a combination thereof in accordance with the
requirements of Section 2.16(b) above or otherwise in a manner reasonably satisfactory to the applicable Revolving Letter of Credit Issuer; 

  
 -117-

 (d) the Swingline Lender will not be required to fund any Swingline Loans unless the
Swingline Lender is reasonably satisfied that any exposure that would result from the exposure to such Defaulting Lender is eliminated or fully covered by the Revolving Credit Commitments of the Non-Defaulting Lenders or a combination thereof in
accordance with the requirements of Section 2.16(b) above; and 
 (e) If the Borrower, the Administrative Agent and
the Revolving Letter of Credit Issuers agree in writing in their discretion that a Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon, as of
the effective date specified in such notice and subject to any conditions set forth therein, such Lender will cease to be a Defaulting Lender and will be a Non-Defaulting Lender and any applicable Cash Collateral shall be promptly returned to the
Borrower and any Revolving Letter of Credit Exposure of such Lender reallocated pursuant to the requirements of Section 2.16(b) shall be reallocated back to such Lender; provided that, except to the extent otherwise expressly
agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender. 

2.17. Permitted Debt Exchanges. 
 (a) Notwithstanding anything to the contrary contained in this Agreement, pursuant to one or more offers (each, a “Permitted Debt Exchange Offer”) made from time to time by the Borrower
to all Lenders (other than any Lender that, if requested by the Borrower, is unable to certify that it is either a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited
investor” (as defined in Rule 501 under the Securities Act)) with outstanding Term Loans under one or more Classes of Term Loans (as determined by the Borrower in its sole discretion) on the same terms, the Borrower may from time to time
consummate one or more exchanges of Term Loans for Permitted Other Notes (such notes, “Permitted Debt Exchange Notes” and each such exchange, a “Permitted Debt Exchange”), so long as the following conditions are
satisfied: (i) no Default or Event of Default shall have occurred and be continuing at the time the offering document in respect of a Permitted Debt Exchange Offer is delivered to the relevant Lenders, (ii) the aggregate principal amount
(calculated on the face amount thereof) of Term Loans exchanged shall equal the aggregate principal amount (calculated on the face amount thereof) of Permitted Debt Exchange Notes issued in exchange for such Term Loans, (iii) the aggregate
principal amount (calculated on the face amount thereof) of all Term Loans exchanged under each applicable Class by the Borrower pursuant to any Permitted Debt Exchange shall automatically be cancelled and retired by the Borrower on date of the
settlement thereof (and, if requested by the Administrative Agent, any applicable exchanging Lender shall execute and deliver to the Administrative Agent an Assignment and Acceptance, or such other form as may be reasonably requested by the
Administrative Agent, in respect thereof pursuant to which the respective Lender assigns its interest in the Term Loans being exchanged pursuant to the Permitted Debt Exchange to the Borrower for immediate cancellation), (iv) if the aggregate
principal amount of all Term Loans (calculated on the face amount thereof) of a given Class tendered by Lenders in respect of the relevant Permitted Debt Exchange Offer (with no Lender being permitted to tender a principal amount of Term Loans which
exceeds the principal amount thereof of the applicable Class actually held by it) shall exceed the maximum aggregate principal amount of Term Loans of such Class offered to be exchanged by the Borrower pursuant to such Permitted Debt Exchange Offer,
then the Borrower shall exchange Term Loans under the relevant Class tendered by such Lenders ratably up to such maximum based on the respective principal amounts so tendered, or if such Permitted Debt Exchange Offer shall have been made with
respect to multiple Classes without specifying a maximum aggregate principal amount offered to be 

  
 -118-

 
exchanged for each Class, and the aggregate principal amount of all Term Loans (calculated on the face amount thereof) of all Classes tendered by Lenders in respect of the relevant Permitted Debt
Exchange Offer (with no Lender being permitted to tender a principal amount of Term Loans which exceeds the principal amount thereof actually held by it) shall exceed the maximum aggregate principal amount of Term Loans of all relevant Classes
offered to be exchanged by the Borrower pursuant to such Permitted Debt Exchange Offer, then the Borrower shall exchange Term Loans across all Classes subject to such Permitted Debt Exchange Offer tendered by such Lenders ratably up to such maximum
amount based on the respective principal amounts so tendered, (v) each such Permitted Exchange Offer shall be made on a pro rata basis to the Lenders (other than any Lender that, if requested by the Borrower, is unable to certify that it is
either a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (as defined in Rule 501 under the Securities Act)) of each applicable Class based on their
respective aggregate principal amounts of outstanding Term Loans under each such Class, (vi) all documentation in respect of such Permitted Debt Exchange shall be consistent with the foregoing, and all written communications generally directed
to the Lenders in connection therewith shall be in form and substance consistent with the foregoing and made in consultation with the Borrower and the Administrative Agent, and (vii) any applicable Minimum Tender Condition or Maximum Tender
Condition, as the case may be, shall be satisfied or waived by the Borrower. 
 (b) With respect to all Permitted Debt Exchanges
effected by the Borrower pursuant to this Section 2.17, (i) such Permitted Debt Exchanges (and the cancellation of the exchanged Term Loans in connection therewith) shall not constitute voluntary or mandatory payments or prepayments
for purposes of Section 5.1 or 5.2, and (ii) such Permitted Debt Exchange Offer shall be made for not less than $50,000,000 in aggregate principal amount of Term Loans, provided that subject to the foregoing clause
(ii) the Borrower may at its election specify (A) as a condition (a “Minimum Tender Condition”) to consummating any such Permitted Debt Exchange that a minimum amount (to be determined and specified in the relevant
Permitted Debt Exchange Offer in the Borrower’s discretion) of Term Loans of any or all applicable Classes be tendered and/or (B) as a condition (a “Maximum Tender Condition”) to consummating any such Permitted Debt
Exchange that no more than a maximum amount (to be determined and specified in the relevant Permitted Debt Exchange Offer in the Borrower’s discretion) of Term Loans of any or all applicable Classes will be accepted for exchange. 

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

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

 SECTION 3. Letters of Credit. 

3.1. Issuance of Letters of Credit. 
 (a) Revolving Letters of Credit. (i) Subject to and upon the terms and conditions herein set forth, at any time and from time to time on and after the Closing Date and prior to the 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; provided that, to the extent that the 2011 Revolving Credit Commitment Extension Effective Date has occurred, no Revolving
Letter of Credit, other than an Optional Revolving Letter of Credit, may have an expiration date occurring later than the Original Revolving L/C Maturity Date if on such date of issuance, the aggregate Stated Amount of all Revolving Letters of
Credit having expiration dates after the Original Revolving L/C Maturity Date (including such newly issued Revolving Letter of Credit but excluding any Optional Revolving Letters of Credit), when added to the aggregate Revolving Credit Exposure of
all 2016 Revolving Credit Lenders (exclusive of Revolving Letter of Credit Exposure with respect to such Revolving Letters of Credit) as of such date, would exceed the Total 2016 Revolving Credit Commitment then in effect; (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. Notwithstanding the proviso to clause (C) of this Section 3.1(a)(ii), any Revolving Letter of Credit Issuer,
at its sole and absolute discretion, may issue a Revolving Letter of Credit (each, an “Optional Revolving Letter of Credit”) having an expiration date occurring later than the Original Revolving L/C Maturity Date but earlier than
the Revolving L/C Maturity Date notwithstanding that, on such date of issuance or at any time thereafter, the aggregate Stated Amount of all Revolving Letters of Credit having expiration dates after the Original Revolving L/C Maturity Date
(including such Optional Revolving Letter of Credit and any other Optional Letters of Credit), when added to the aggregate Revolving Credit Exposure of all 2016 Revolving Credit Lenders (exclusive of Revolving Letter of Credit Exposure with respect
to such 

  
 -120-

 
Revolving Letters of Credit) as of such date, may exceed the Total 2016 Revolving Credit Commitment then in effect. Any such Revolving Letter of Credit Issuer may require, as a condition to
issuing any such an Optional Revolving Letter of Credit in its sole and absolute discretion, that the Borrower Cash Collateralize the Revolving L/C Obligations with respect to such Optional Revolving Letters of Credit to the extent of the excess
referred to in the preceding sentence (at such times as such Revolving Letter of Credit Issuer may required), or make other arrangements satisfactory to such Revolving Letter of Credit Issuer, to eliminate or cover the exposure of such Revolving
Letter of Credit Issuer with respect to such excess. Notwithstanding anything contained in this Agreement to the contrary, at no time prior to the Original Revolving L/C Maturity Date shall the aggregate Stated Amount of all Revolving Letters of
Credit having expiration dates after the Original Revolving L/C Maturity Date (excluding any Optional Revolving Letters of Credit), when added to the aggregate Revolving Credit Exposure of all 2016 Revolving Credit Lenders (exclusive of Revolving
Letter of Credit Exposure with respect to such Revolving Letters of Credit) as of such date, exceed the Total 2016 Revolving Credit Commitment then in effect. 
 (b) Deposit Letters of Credit. (i) Subject to and upon the terms and conditions herein set forth, at any time and from time to time on and after the Closing Date and prior to the Deposit L/C
Termination 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.

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

  
 -121-

 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 subject to the limitation set forth in the proviso
of Section 3.1(a)(ii)(C), and in the case of any Deposit Letter of Credit, the Deposit L/C Termination Date; provided, however, that such Letter of Credit Issuer shall not permit any such extension if (A) such Letter
of Credit Issuer has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of clause
(ii) of either Sections 3.1(a) or (b), as applicable, or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice
Date from the Administrative Agent or the Borrower that one or more of the applicable conditions specified in Section 7 are not then satisfied, and in each such case directing such Letter of Credit Issuer not to permit such extension.

 (c) 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, in 

  
 -122-

 each Revolving Letter of Credit, each substitute therefor, each drawing made thereunder and the obligations
of the Borrower under this Agreement with respect thereto (each, a “Revolving L/C Participation”) pro rata based on such Revolving L/C Participant’s Revolving Credit Commitment Percentage (determined without regard to the Class
of Revolving Credit Commitments held by such Lender), and any security therefor or guaranty pertaining thereto. 
 (b) In
determining whether to pay under any Revolving Letter of Credit, the Revolving Letter of Credit Issuer shall have no obligation relative to the Revolving L/C Participants other than to confirm that (i) any documents required to be delivered
under such Revolving Letter of Credit have been delivered, (ii) the Revolving Letter of Credit Issuer has examined the documents with reasonable care and (iii) the documents appear to comply on their face with the requirements of such
Revolving Letter of Credit. Any action taken or omitted to be taken by the Revolving Letter of Credit Issuer under or in connection with any Revolving Letter of Credit issued by it, if taken or omitted in the absence of gross negligence or willful
misconduct, shall not create for the Revolving Letter of Credit Issuer any resulting liability. 
 (c) Whenever the Revolving
Letter of Credit Issuer receives a payment in respect of an unpaid reimbursement obligation as to which the Administrative Agent has received for the account of the Revolving Letter of Credit Issuer any payments from the Revolving L/C Participants,
the Revolving Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each Revolving L/C Participant that has paid its Revolving Credit Commitment Percentage (determined without regard to the
Class of Revolving Credit Commitments held by such Lender) of such reimbursement obligation, in Dollars and in immediately available funds, an amount equal to such Revolving L/C Participant’s share (based upon the proportionate aggregate amount
originally funded by such Revolving L/C Participant to the aggregate amount funded by all Revolving L/C Participants) of the principal amount so paid in respect of such reimbursement obligation and interest thereon accruing after the purchase of the
respective Revolving L/C Participations at the Overnight Rate. For the avoidance of doubt, all distributions under this Section 3.3(c) shall be made to each Lender with a Revolving Credit Commitment pro rata based on each such
Lender’s Revolving Credit Commitment Percentage without regard to the Class of Revolving Credit Commitments held by such Lender. 
 (d) The obligations of the Revolving L/C Participants to make payments to the Administrative Agent for the account of the Revolving Letter of Credit Issuer with respect to Revolving Letters of Credit
shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including
under any of the following circumstances: 
 (i) any lack of validity or enforceability of this Agreement or any
of the other Credit Documents; 
 (ii) the existence of any claim, set-off, defense or other right that the
Borrower may have at any time against a beneficiary named in a Revolving Letter of Credit, any transferee of any Revolving Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, the Revolving Letter of
Credit Issuer, any Lender or other Person, whether in connection with this Agreement, any Revolving Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower and
the beneficiary named in any such Revolving Letter of Credit); 
 (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; 

  
 -123-

 (iv) the surrender or impairment of any security for the performance or
observance of any of the terms of any of the Credit Documents; or 
 (v) the occurrence of any Default or Event
of Default; 
 provided, however, that no Revolving L/C Participant shall be obligated to pay to the Administrative Agent for the
account of the Revolving Letter of Credit Issuer its Revolving Credit Commitment Percentage of any unreimbursed amount arising from any wrongful payment made by the Revolving Letter of Credit Issuer under a Revolving Letter of Credit as a result of
acts or omissions constituting willful misconduct or gross negligence on the part of the Revolving Letter of Credit Issuer. 

(e) On the 2011 Revolving Credit Commitment Extension Effective Date, the Revolving L/C Participations in any issued and outstanding
Revolving Letters of Credit shall be reallocated so that after giving effect thereto the 2016 Revolving Credit Lenders and the 2013 Revolving Credit Lenders shall share ratably in such Revolving L/C Participations in accordance with the aggregate
Revolving Credit Commitments (including both the 2013 Revolving Credit Commitments and the 2016 Revolving Credit Commitments from time to time in effect). ThereafterOn the December 2012 Extension Amendment Effective Date, the
Revolving L/C Participations in any issued and outstanding Revolving Letters of Credit shall be reallocated so that after giving effect thereto the 2016 Revolving Credit Lenders and the 2013 Revolving Credit Lenders shall share ratably in such
Revolving L/C Participations in accordance with the aggregate Revolving Credit Commitments (including both the 2013 Revolving Credit Commitments and the 2016 Revolving Credit Commitments from time to time in effect). After the 2011
Revolving Credit Commitment Extension Effective Date, until the Original Revolving L/C Maturity Date, Revolving L/C Participations in any newly-issued Revolving Letters of Credit shall be allocated in accordance with the aggregate Revolving
Credit Commitments (including both the 2013 Revolving Credit Commitments and the 2016 Revolving Credit Commitments from time to time in effect). Notwithstanding anything contained in this Agreement to the contrary, to the extent that the
2011 Revolving Credit Commitment Extension Effective Date has occurred, on the Original Revolving L/C Maturity Date, the interests and participations of the 2013 Revolving Lenders in the Revolving Letters of Credit (if any) outstanding as
at such day shall automatically terminate at the close of business on such date and (i) from and after the Original Revolving L/C Maturity Date, the 2013 Revolving Credit Lenders shall have no liability arising from, relating to, in connection
with or otherwise in respect of, such interests and participations or Revolving Letter of Credit, and (ii) such interests and participations in outstanding Revolving Letters of Credit shall thereupon automatically and without further action be
re-allocated to the extent necessary such that the interests and participations in such Revolving Credit Letters of Credit shall be held by the 2016 Revolving Credit Lenders ratably in proportion to their respective 2016 Revolving Credit
Commitments. 
 3.4. Agreement to Repay Letter of Credit Drawings. 

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

  
 -124-

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

  
 -125-

 3.5. Increased Costs. If after the Closing Date, 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 Closing Date (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 Closing Date. 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. 
 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 

  
 -126-

 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. 
 (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 

  
 -127-

 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 be liable 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. 
 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 Agreement, “Cash Collateralize” means to pledge and deposit with or deliver to the
Administrative Agent, for the benefit of the Revolving Letter of Credit Issuers or Swingline Lender, as applicable, as collateral for the Revolving L/C Obligations and Revolving Credit Lender reimbursement obligations in respect of Swingline Loans,
as the case may be, cash or deposit account balances (“Cash Collateral”) in an amount equal to 100% of the amount of the Revolving Letters of Credit Outstanding or Swingline Loans, as the case may be, required to be Cash
Collateralized pursuant to documentation in form and substance reasonably satisfactory to the Administrative Agent and the Revolving Letter of Credit Issuers or Swingline Lender, as the case may be (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 Issuers and the Swingline Lender, as applicable, 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, the Revolving Letter of Credit Issuers and the Swingline Lender
(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 established the Citibank 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, were deposited into the Citibank Deposit L/C Loan Collateral Account such that the 

  
 -128-

 
Deposit L/C Loan Collateral Account Balance equaled at least the Deposit Letters of Credit Outstanding. After the Amendment No. 2 Effective Date, the Borrower may establish additional
Deposit L/C Loan Collateral Accounts for the purpose of cash collateralizing the Borrower’s obligations to any Deposit Letter of Credit Issuer, and may transfer all or any portion of the funds in any Deposit L/C Loan Collateral Account to any
other Deposit L/C Loan Collateral Account, subject to the satisfaction of the conditions set forth in this Section 3.9. The Borrower agrees that at all times, and shall immediately cause additional funds to be deposited and held in the
Deposit L/C Loan Collateral Accounts from time to time in order that, (A) the Deposit L/C Loan Collateral Account Balance shall at least equal the Deposit Letters of Credit Outstanding and (B) the aggregate amount on deposit in the
Citibank Deposit L/C Loan Collateral Account shall at least equal the Deposit Letters of Credit Outstanding in respect of all Citibank Deposit Letters of Credit. The Borrower hereby grants to the Collateral Agent, for the benefit of all Deposit
Letter of Credit Issuers, a security interest in the Deposit L/C Loan Collateral Accounts 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 (x) amounts on deposit in the Citibank Deposit L/C Loan Collateral Account shall be applied, first, to repay the Deposit L/C
Obligations in respect of Citibank Deposit Letters of Credit, second, to repay the Deposit L/C Obligations in respect of all other Deposit Letters of Credit and, then, to repay all other Obligations and (y) amounts on deposit in any other
Deposit L/C Loan Collateral Account shall be applied, first, to repay the corresponding Deposit L/C Obligations, second, to repay the Deposit L/C Obligations in respect of all other Deposit Letters of Credit and, then, to repay 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 any 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 applicable depositary bank (each, a “Depositary Bank”) of the applicable 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 Citibank Deposit L/C Loan Collateral Account shall be invested by the applicable Depositary Bank in Permitted Investments and, prior to the 2014
Deposit L/C Loan Maturity Date, in the manner as instructed by the Citibank, N.A. and, on and after the 2014 Deposit L/C Loan Maturity Date, in the manner instructed by the Borrower (and agreed to by such Depositary Bank). Amounts in any other
Deposit L/C Loan Account, other than the Citibank Deposit L/C Loan Collateral Account, shall be invested by the applicable Depositary Bank in the manner instructed by the Borrower (and agreed to by such Depositary Bank). Prior to the 2014 Deposit
L/C Loan Maturity Date and to the extent amounts in the Citibank Deposit L/C Loan Collateral Account are invested in anything other than Deposit L/C Permitted Investments, Citibank, N.A. shall bear the risk of loss of principal with respect to any
such investments. The Borrower shall bear the risk of loss of principal with respect any other investments in any Deposit L/C Collateral Account. 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
applicable Depositary Bank to release and pay to the Borrower) any amounts on deposit in the Deposit L/C Loan Collateral Accounts 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 Accounts 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.

businesses of the Parent and its other Subsidiaries, US Holdings or such Restricted Subsidiaries.

Lender pro rata on the basis of their respective Revolving Letter of Credit Exposure, a fee in respect of each Revolving Letter of Credit (the “2016 Revolving Letter of Credit Fee”), for the period from the date of issuance

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

Loans of any Extension Series (including the 2017 Term Loans) any mandatory prepayment (1) made pursuant to Section 5.2(a)(ii) unless such prepayment is accompanied by at least a pro rata prepayment, based upon the applicable
remaining Repayment Amounts due in respect thereof, of Term Loans of the Existing Term Loan Class or Classes, if any, from which such Extended Term Loans were exchanged (or such Term Loans of the Existing Term Loan Class or Classes have otherwise
been repaid in full) or (2) made pursuant to Section 5.2(a)(iii) unless all 2014 Term Loans have been repaid in full; (B) the Borrower may not allocate any mandatory prepayments made pursuant to Section 5.2(a)(i) to
any Class of Term Loans unless such prepayment is accompanied by at least a pro rata repayment, based upon the applicable remaining Repayment Amounts due in respect thereof, of Term Loans of the Existing Term Loan Class, if any, from which
such Class of Term Loans was exchanged and Extended Term Loans, if any, that were originally converted from such Class of Term Loans (or the Existing Term Loan Class, if any, from which such Class of Term Loans was converted); and
(C) prepayments within any Class of Term Loans must be applied (1) pro rata to the Lenders, based upon the outstanding principal amounts owing within such Class of Term Loans and (2) to reduce the scheduled Repayment
Amounts in direct order of maturity. 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 each Class of Term Loans) requesting that the Administrative Agent provide notice of such prepayment to
each Lender of Term Loans. 
 (ii) Each prepayment of Term Loans required by Section 5.2(a)(iv) shall be allocated
pro rata among the 2014 Term Loans, the 2017 Term Loans, the Incremental Term Loans, and the Extended Term Loans (other than the 2017 Term Loans) based upon the applicable remaining Repayment Amounts due in respect thereof and be applied to
reduce the scheduled Repayment Amounts in direct 

  
 -136-

 
order of maturity; provided that, subject to the pro rata application to Lenders, based upon the outstanding principal amounts owing 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 only to the following limitations: (A) the Borrower shall not allocate to Extended Term Loans of any Extension Series
(including the 2017 Term Loans) any mandatory prepayment made pursuant to Section 5.2(a)(iv) unless such prepayment is accompanied by at least a pro rata prepayment, based upon the applicable remaining Repayment Amounts due in
respect thereof, of Term Loans of the Existing Term Loan Class or Classes, if any, from which such Extended Term Loans were exchanged (or such Term Loans of the Existing Term Loan Class or Classes have otherwise been repaid in full) and
(B) prepayments within any Class of Term Loans must be applied (1) pro rata to Lenders, based upon the outstanding principal amounts owing within any Class of Term Loans and (2) to reduce the scheduled Repayment Amounts in
direct order of maturity. Each prepayment of Deposit L/C Loans required by Section 5.2(a)(iv) shall be allocated pro rata among the 2014 Deposit L/C Loans, the 2017 Deposit L/C Loans, the Incremental Deposit L/C Loans and the
Extended Deposit L/C Loans (other than the 2017 Deposit L/C Loans) based on the outstanding principal amounts due thereon; provided that, subject to the pro rata application to Lenders, based upon the outstanding principal amounts
owing within any Class of Deposit L/C Loans, the Borrower may allocate such prepayment in its sole discretion among the Class or Classes of Deposit L/C Loans as the Borrower may specify, subject to the limitation that the Borrower shall not allocate
to Extended Deposit L/C Loans of any Extension Series (including the 2017 Deposit L/C Loans) any mandatory prepayment made pursuant to Section 5.2(a)(iv) unless such prepayment is accompanied by at least a pro rata prepayment to
the Lenders, based upon the outstanding principal amount owing of Deposit L/C Loans of the Existing Deposit L/C Loan Class or Classes, if any, from which such Extended Deposit L/C Loans were exchanged (or such Deposit L/C Loans of the Existing
Deposit L/C Loan Class or Classes have otherwise been repaid in full). 
 (d) Application to Term Loans and Deposit L/C
Loans. With respect to each prepayment of Term Loans and Deposit L/C Loans elected to be made by the Borrower pursuant to Section 5.1 or required by Section 5.2(a), the Borrower may designate the Types of Loans that are
to be prepaid and the specific Borrowing(s) pursuant to which made; provided that 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. 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. 
 (e)
Application to Revolving Credit Loans; Mandatory Commitment Reductions. (i) 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(a)(iv) or 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(a)(iv) or 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. 

  
 -137-

 (ii) With respect to each mandatory reduction and termination of Revolving Credit
Commitments, other Extended Revolving Credit Commitments and New Revolving Credit Commitments required by Section 5.2(a)(iv) or Section 10.1(y)(ii), the Borrower may designate (A) the Classes of Commitments to be reduced
and terminated and (B) the corresponding Classes of Loans to be prepaid; provided that (x) any such reduction and termination of 2016 Revolving Credit Commitments shall apply proportionately and permanently to reduce the 2016
Revolving Credit Commitments of each of the 2016 Revolving Credit Lenders, except that, notwithstanding the foregoing, (1) subject to the pro rata termination or reduction of 2016 Revolving Credit Commitments of each of the 2016
Revolving Credit Lenders, the Borrower may allocate any termination or reduction of Revolving Credit Commitments in its sole discretion among the Classes of Revolving Credit Commitments as the Borrower may specify and (2) the Borrower may
allocate any termination or reduction of Revolving Credit Commitments amongst the 2013 Revolving Credit Lenders in its sole discretion as the Borrower may specify and (y) after giving effect to such termination or reduction and to any
prepayments of Loans or cancellation or cash collateralization of letters of credit made on the date of each such reduction and termination in accordance with this Agreement, the aggregate amount of such Lenders’ credit exposures shall not
exceed the remaining Commitments of such Lenders’ in respect of the Class reduced and terminated. In connection with any such termination or reduction, to the extent necessary, the participations hereunder in outstanding Revolving Letters of
Credit and Swingline Loans may be required to be reallocated and Revolving Credit Loans outstanding prepaid and then reborrowed, in each case in the manner contemplated by the last three sentences of Section 2.14(h)(i) (as modified to
account for a termination or reduction, as opposed to an increase, of Revolving Credit Commitments). 
 (iii) For the avoidance
of doubt, prior to the 2013 Revolving Credit Maturity Date, the amount of any prepayment of Revolving Credit Loans elected to be made by the Borrower pursuant to Section 5.1 shall be allocated among the Revolving Credit Loans of each
Lender pro rata based on each such Lender’s Revolving Credit Commitment Percentage without regard to the Class of the Revolving Credit Commitments held by such Lender. 

(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. 

  
 -138-

 (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) (other than prepayments made in connection with any Debt Incurrence Prepayment Event or New Debt Incurrence Prepayment Event), 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) (other than prepayments made in connection with any Debt Incurrence Prepayment Event or New Debt Incurrence Prepayment Event) (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”). 
 (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. 
 (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). 

  
 -140-

 (c) The Borrower shall indemnify and hold harmless the Administrative Agent, the Posting
Agent, the Collateral Agent and each Lender within fifteen Business Days after written demand therefor, for the full amount of any Indemnified Taxes imposed on the Administrative Agent, the Posting Agent, the Collateral Agent or such Lender as the
case may be, on or with respect to any payment by or on account of any obligation of the Borrower or any Guarantor hereunder or under any other Credit Document (including Indemnified Taxes imposed or asserted on or attributable to amounts payable
under this Section 5.4) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate
setting forth reasonable detail as to the amount of such payment or liability delivered to the Borrower by a Lender, the Administrative Agent, the Posting Agent or the Collateral Agent (as applicable) on its own behalf or on behalf of a Lender shall
be conclusive absent manifest error. 
 (d) Any Non-U.S. Lender that is entitled to an exemption from or reduction of
withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or under any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Credit Document shall, to the
extent it is legally able to do so, deliver to the Borrower (with a copy to the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent)), at the time or times prescribed by Applicable Law or reasonably requested by the
Borrower or the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent), such properly completed and executed documentation prescribed by Applicable Law as will permit such payments to be made without withholding or at a
reduced rate of withholding. A Lender’s obligation under the prior sentence shall apply only if the Borrower or the Administrative Agent has made a request for such documentation. In addition, any Lender, if requested by the Borrower or the
Administrative Agent (or, in the case of the Posting Facility, the Posting Agent), shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent (or, in the case of the
Posting Facility, the Posting Agent) as will enable the Borrower or the Administrative Agent (or, in the case of the Posting Facility, the Posting Agent) to determine whether or not such Lender is subject to backup withholding or information
reporting requirements. 
 (e) Each Non-U.S. Lender with respect to any Loan or Posting Advance made to the Borrower shall, to
the extent it is legally entitled to do so: 
 (i) deliver to the Borrower and the Administrative Agent
(or, in the case of the Posting Facility, the Posting Agent), prior to the date on which the first payment to the Non-U.S. Lender is due hereunder, two copies of (x) in the case of a Non-U.S. Lender claiming exemption from U.S. federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, United States Internal Revenue Service Form W-8BEN (together with a certificate substantially in the form of Exhibit
Q representing that such Non-U.S. Lender is not a bank for purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower, any interest payment received
by such non-U.S. Lender under this Agreement or any other Credit Document is not effectively connected with the conduct of a trade or business in the United States and is not a controlled foreign corporation related to the Borrower (within the
meaning of Section 864(d)(4) of the Code)), (y) Internal Revenue Service Form W-8BEN or Form W-8ECI, in each case properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, U.S.
Federal withholding tax on payments by the Borrower under this Agreement or (z) if a Non-U.S. Lender does not act or ceases to act for its own account with respect to any portion of any sums paid or payable to such Lender under any of the
Credit Documents (for example, in the case of a typical participation or where Non-U.S. Lender is a pass through entity) Internal Revenue Service Form W-8IMY and all necessary attachments (including the forms described in clauses (x) and
(y) above, as required); and 

  
 -141-

 (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). 
 (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), 

  
 -142-

 
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. 
 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. 

  
 -143-

 (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. 

(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. 

SECTION 6. Conditions Precedent to Initial Borrowing. 
 The initial Borrowing under this Agreement is subject to the satisfaction of the following conditions precedent, except as otherwise agreed between the Borrower and the Administrative Agent. 

6.1. Credit Documents. The Administrative Agent (or, in the case of clause (f), the Posting Agent) shall have received:

direct or indirect parent of the Parent or (B) the Borrower’s (or US Holdings’, the Parent’s or any direct or indirect parent thereof), as applicable, Form 10-K or 10-Q, as applicable, filed with the SEC; provided that,
with respect to each of subclauses (A) and (B) of this paragraph, to the extent such information relates to US Holdings, the Parent or a parent of the Parent, such information is accompanied by consolidating or other
information that explains in reasonable detail the differences between the information relating to US Holdings, the Parent or such parent, on the one hand, and the information relating to the Borrower and the Restricted Subsidiaries on a standalone
basis, on the other hand. 
 9.2. Books, Records and Inspections. The Borrower will, and will cause each Restricted
Subsidiary to, permit officers and designated representatives of the Administrative Agent or the Required Lenders (as accompanied by the Administrative Agent) to visit and inspect any of the properties or assets of the Borrower or such Restricted
Subsidiary in whomsoever’s possession to the extent that it is within such party’s control to permit such inspection (and shall use commercially reasonable efforts to cause such inspection to be permitted to the extent that it is not
within such party’s control to permit such inspection), and to examine the books and records of the Borrower and any such Restricted Subsidiary and discuss the affairs, finances and accounts of the Borrower and of any such Restricted Subsidiary
with, and be advised as to the same by, its and their officers and independent accountants, all at such reasonable times and intervals and to such reasonable extent as the Administrative Agent or Required Lenders may desire (and subject, in the case
of any such meetings or advice from such independent accountants, to such accountants’ customary policies and procedures); provided that, excluding any such visits and inspections during the continuation of an Event of Default
(a) only the Administrative Agent, whether on its own or in conjunction with the Required Lenders, may exercise rights of the Administrative Agent and the Lenders under this Section 9.2, (b) the Administrative Agent shall not

Required Lenders shall give the Borrower the opportunity to participate in any discussions with the Borrower’s independent public accountants. 
 9.3. Maintenance of Insurance. The Borrower will, and will cause each Material Subsidiary that is a Restricted Subsidiary to, at all times maintain in full force and effect, pursuant to
self-insurance arrangements or with insurance companies that the Borrower believes (in the good faith judgment of the management of the Borrower, as applicable) are financially sound and responsible at the time the relevant coverage is placed or
renewed, insurance in at least such amounts (after giving effect to any self-insurance which the Borrower believes (in the good faith judgment of management of the Borrower, as applicable) is reasonable and prudent in light of the size and nature of
its business) and against at least such risks (and with such risk retentions) as the Borrower believes (in the good faith judgment of management of the Borrower, as applicable) is reasonable and prudent in light of the size and nature of its
business; and will furnish to the Administrative Agent, upon written reasonable request from the Administrative Agent, information presented in reasonable detail as to the insurance so carried. With respect to each Mortgaged Property, obtain flood
insurance in such total amount as the Administrative Agent may from time to time require, if at any time the area in which any improvements located on any Mortgaged Property is designated a “flood hazard area” in any Flood Insurance Rate
Map published by the Federal Emergency Management Agency (or any successor agency), and otherwise comply with the National Flood Insurance Program as set forth in the Flood Disaster Protection Act of 1973, as amended from time to time.

and all lawful claims in respect of any Taxes imposed, assessed or levied that, if unpaid, could reasonably be expected to become a material Lien upon any properties of the Borrower or any 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. 

9.5. Consolidated Corporate Franchises. The Borrower will do, and will cause each Material Subsidiary that is a Restricted
Subsidiary to do, or cause to be done, all things necessary to preserve and keep in full force and effect its existence, corporate rights and authority, except to the extent that the failure to do so could not reasonably be expected to have a
Material Adverse Effect; provided, however, that the Borrower and the Restricted Subsidiaries may consummate any transaction permitted under Section 10.3, 10.4 or 10.5. 

9.6. Compliance with Statutes, Regulations, Etc. The Borrower will, and will cause each Restricted Subsidiary to, comply with all
Applicable Laws applicable to it or its property, including all governmental approvals or authorizations required to conduct its business, and to maintain all such governmental approvals or authorizations in full force and effect, in each case
except where the failure to do so could not reasonably be expected to have a Material Adverse Effect.

other senior officer of the Borrower setting forth details as to such occurrence and the action, if any, that the Borrower or such ERISA Affiliate is required or proposes to take, together with any notices (required, proposed or otherwise) given to

(including the giving of written notice thereof); that a proceeding has been instituted against the Borrower or an ERISA Affiliate pursuant to Section 515 of ERISA to collect a delinquent contribution to a Plan; that the PBGC has notified the

 -157-

 
Affiliate may request with respect to any Multiemployer Plan and (ii) any notices described in Section 101(l) of ERISA that the Borrower and any of the Restricted Subsidiaries or any
ERISA Affiliate may request with respect to any Multiemployer Plan; provided that if the Borrower, any of such Restricted Subsidiaries or any ERISA Affiliate has not requested such documents or notices from the administrator or sponsor of the
applicable Multiemployer Plan, the Borrower, the applicable Restricted Subsidiary(ies) or the ERISA Affiliate(s) shall promptly make a request for such documents or notices from such administrator or sponsor and shall provide copies of such
documents and notices promptly after receipt thereof. 
 (c) Upon the reasonable request of the Administrative Agent, the

practice the Parent and any of its other Subsidiaries, including the Oncor Subsidiaries) on terms that are, taken as a whole, substantially as favorable to the Borrower or such Restricted Subsidiary as it would obtain in a comparable
arm’s-length transaction with a Person that is not an Affiliate; provided that the foregoing restrictions shall not apply to:

Mortgage may be delivered within a commercially reasonable period of time after the delivery of a Mortgage if they are not reasonably available at the time the Mortgage is delivered. 

(d) With respect to any Post-Closing Mortgaged Property, within 120 days (or 180 days in the case of Collateral consisting of mining

(confirmed in writing to the Borrower and the Administrative Agent) that the cost or other consequences (including adverse tax and accounting consequences) of creating or perfecting any Lien on any property is excessive in relation to the benefits
afforded to the Secured Party thereby, then such property may be excluded from the Collateral for all purposes of the Credit Documents. 
 (f) Within 140 days after Final Completion of construction (as defined in the applicable engineering, procurement and constructions contract, “EPC Contract”) of each of the Oak Grove
(which, for the purposes of this Section 9.14(f), shall include Oak Grove Unit 1 and Oak Grove 

  
 -161-

subcontractors relating to such Project as shall be required to be delivered pursuant to the applicable EPC Contract and shall use commercially reasonable efforts to deliver to the Collateral Agent such other lien waivers from such contractors and

(unless such Letters of Credit have been collateralized on terms and conditions reasonably satisfactory to the applicable Letter of Credit Issuer following the termination of the Revolving Credit Commitments or the repayment of the Deposit L/C
Loans, as the case may be) and the Loans, Posting Advances and Unpaid Drawings, together with interest, fees and all other Obligations (other than Hedging Obligations under Secured Hedging Agreements and/or Secured Commodity Hedging Agreements, Cash
Management Obligations under Secured Cash Management Agreement or contingent indemnification obligations for which no claim has been made), are paid in full: 
 10.1. Limitation on Indebtedness. The Borrower will not, and will not permit the Restricted Subsidiaries to, create, incur, assume or suffer to exist any Indebtedness; provided that

immediately before and after giving effect to such incurrence, no Default shall have occurred and be continuing and (y) on a Pro Forma Basis, after giving effect to such incurrence, the Consolidated EBITDA to Consolidated Interest Expense Ratio

with the total amount of outstanding Indebtedness incurred by Restricted Subsidiaries that are not Subsidiary Guarantors pursuant to Sections 10.1(d), 10.1(j), 10.1 (k) and 10.1(n), exceeding $1,250,000,000.

Section 10.6(u)) and maintained, on and after the Amendment No. 2 Effective Date, on the terms set forth in the SG&A Note), (2) the Existing P&I Note (as defined in Amendment No. 2) (in the case of any Parent Loan
made prior to the Amendment No. 2 Effective Date pursuant to Section 10.6(r) or Section 10.6(t)) and maintained, on and after the Amendment No. 2 Effective Date, on the terms set forth in the P&I Note or

provision such that each Parent Loan shall be repaid with the proceeds from the Disposition of all or any portion of the Stock or Indebtedness of, or all or substantially all of the assets (in one transaction or a series of related transactions) of

at maturity) any Indebtedness of the Parent or to make any dividend or distribution to the Sponsors and (iii) on and after the Amendment No. 2 Effective Date contain a covenant that requires the sum of (without duplication) (A) the
aggregate amount of outstanding senior secured indebtedness (including guarantees) of Parent and any subsidiary of Parent, including EFIH, that is secured on a second priority basis by the equity interests that EFIH owns in Oncor Holdings (such
indebtedness, the “EFIH Second Priority Debt”) plus (B) the aggregate amount of outstanding Parent Loans (including, the SG&A Note and P&I Note) (such sum, the “Parent Loan Combined Debt Amount”), not
to exceed, at any time, the maximum amount of EFIH Second Priority Debt permitted by the EFH 10% Indenture, as such indenture is in effect on the Amendment No. 2 Effective Date (the “Parent Loan Debt Limit”). 

Notwithstanding the foregoing, after the Amendment No. 2 Effective Date, the Borrower shall (A) not make any Parent Loan
(w) under the SG&A Note or otherwise under Section 10.6(d), (x) to the extent that, after giving effect to such Parent Loan, the Parent Loan Combined Debt Amount would exceed the Parent Loan Debt Limit, (y) that would
result in the aggregate principal amount of all Parent 

  
 -188-

 
Loans outstanding at any time under the P&I Note or otherwise under Section 10.6(r) and Section 10.6(t) exceeding $2,000,000,000 or (z) after the occurrence of a
“Permitted Asset Transfer” as defined in the EFH 10% Indenture, as such indenture is in effect on the Amendment No. 2 Effective Date, and (B) demand repayment of Parent Loans (x) to the extent that the Parent Loan Combined
Debt Amount exceeds the Parent Loan Debt Limit, which payment shall be in an amount no less than such excess and (y) in their entirety upon the occurrence of a Permitted Asset Transfer. 

10.7. Limitations on Debt Payments and Amendments. 
 (a) The Borrower will not, and will not permit the Restricted Subsidiaries to, prepay, repurchase or redeem or otherwise defease any Permitted Additional Debt that is subordinated to the Obligations or
any Existing Notes with Stated Maturities beyond the 2014 Term Loan Maturity Date (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 (including under the Intercompany Subordinated Note) owed among the Borrower and/or the Restricted Subsidiaries, in either case unless 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.

to, or caused by, the failure of the Dealer to comply with its payment obligations under any Dealer Swaps, the Borrower shall have a period of seven Business Days to cure any such failure and during such cure period, such failure shall not
constitute a Default or Event of Default hereunder, and provided, further, that to the extent that any such failure to pay is caused by the Posting Lender or the Dealer (to the extent such entities are Affiliates of each other) to
comply with their respective obligations under any netting and/or settlement agreement with the Borrower or any Restricted Subsidiary, such failure to pay shall not (to the extent it is and continues to be caused by such failure) constitute a
Default or Event of Default hereunder; or 
 11.2. Representations, Etc. Any representation, warranty or statement made
or deemed made by any Credit Party herein or in any other Credit Document or any certificate delivered or required to be delivered pursuant hereto or thereto shall prove to be untrue in any material respect on the date as of which made or deemed

maturity thereof; provided that this clause (b) shall not apply to secured Indebtedness that becomes due as a result of the voluntary sale or transfer of the property or assets securing such Indebtedness, if such sale or transfer
is permitted hereunder and under the documents providing for such Indebtedness; or 
 11.5. Bankruptcy, Etc. The Borrower

decision to take or not take action under, this Agreement and the other Credit Documents based on such documents and information as it shall from time to time deem appropriate, which may include, in each case: 

(i) the financial condition, status and capitalization of the Borrower and each other Credit Party; 

(ii) the legality, validity, effectiveness, adequacy or enforceability of this Agreement and each other Credit Document
and any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Credit Document; 
 (iii) determining compliance or non-compliance with any condition hereunder to the making of a Loan or Posting Advance, or the issuance of a Letter of Credit and the form and substance of all evidence
delivered in connection with establishing the satisfaction of each such condition; and 
 (iv) the adequacy,
accuracy and/or completeness of any information delivered by the Administrative Agent, the Posting Agent, any other Lender or by any of their respective Related Parties under or in connection with this Agreement or any other Credit Document, the
transactions contemplated hereby and thereby or any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection with any Credit Document. 

12.4. Reliance by Agents. The Administrative Agent, the Posting Agent and the Collateral Agent shall be entitled to rely, and
shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex, electronic mail, or teletype message, statement, order or other document or instruction believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to US Holdings and/or the Borrower), independent accountants and other experts selected by the
Administrative Agent, the Posting Agent or the Collateral Agent. The Administrative Agent and the Posting Agent may deem and treat the Lender specified in the Register with respect to any amount owing hereunder as the owner thereof for all purposes
unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent and the Posting Agent. The Administrative Agent, the Posting Agent and the Collateral Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Credit Document unless it shall first receive such advice or concurrence of the Required Lenders (or the Required Posting Lenders, as applicable) as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent, the Posting Agent and the
Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Credit Documents in accordance with a request of the Required Lenders (or the 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 

  
 -198-

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

  
 -199-

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

  
 -200-

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

  
 -201-

 (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. 

  
 -202-

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

SECTION 13. Miscellaneous. 
 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 Parties written amendments, supplements or modifications hereto and to the other Credit Documents for the purpose of adding any provisions to this 

  
 -203-

 
Agreement or the other Credit Documents or changing in any manner the rights of the Lenders or of the Credit Parties hereunder or thereunder or (b) waive in writing, on such terms and
conditions as the Required Lenders or the Administrative Agent and/or Collateral Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Credit Documents or any Default or Event of Default
and its consequences; provided, however, that (i) to the extent that any such amendment, supplement, modification or waiver relates 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 Consolidated Interest Expense or in the component definitions thereof shall not constitute a reduction in the rate and only the consent of the Required Lenders shall be necessary to
waive any obligation of the Borrower to pay interest or principal 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 increase in interest rates (provided that to the extent such post-default interest relates to the interest rates applicable under the Posting Facility, the waiver thereof shall
require the consent of the Required Posting Lenders rather than the Required Lenders)), or extend the final expiration date of any Lender’s Commitment or extend the final expiration date of any Revolving Letter of Credit beyond the Revolving
L/C Maturity Date or extend the final expiration date of any Deposit Letter of Credit beyond the Deposit L/C Termination Date, or increase the aggregate amount of the Commitments of any Lender, or amend or modify any provisions of
Section 5.3(a) (with respect to the ratable allocation of any payments only) and 13.8(a) and 13.19 or make any Loan, Posting Advance, interest, Fee or other amount payable in any currency other than expressly provided
herein, in each case without the written consent of each Lender directly and adversely affected thereby; or 

(ii) amend, modify or waive any provision of this Section 13.1 or reduce the percentages specified in the
definition of the term “Required Lenders”, “Required Revolving Credit Lenders”, “Required 2014 Term Loan Lenders”, “Required 2017 Term Loan Lenders”, “Required Term Loan Lenders”, “Required
Deposit L/C Loan Lenders” or “Required Posting Lenders”, consent to the assignment or transfer by U.S. Holdings or the Borrower of their respective rights and obligations under any Credit Document to which it is a party (except as
permitted pursuant to Section 10.3) or alter the order of application set forth in Section 5.2(c)(i) or in the Intercreditor Agreement, in each case without the written consent of each Lender directly and adversely affected
thereby, or 
 (iii) amend, modify or waive any provision of Section 12 without the written consent
of the then-current Administrative Agent, Posting Agent and Collateral Agent or any other former or current Agent to whom Section 12 then applies in a manner that directly and adversely affects such Person, or 

(iv) amend, modify or waive any provision of Section 3 with respect to any Letter of Credit without the
written consent of the applicable Letter of Credit Issuer, or 

  
 -204-

 (v) amend, modify or waive any provisions hereof relating to Swingline Loans
without the written consent of the Swingline Lender, or 
 (vi) change any Revolving Credit Commitment to an
Incremental Term Loan Commitment, or change any Incremental Term Loan Commitment to a Revolving Credit Commitment, in each case without the prior written consent of each Lender directly and adversely affected thereby, or 

(vii) release all or substantially all of the Guarantors under the Guarantee (except as expressly permitted by the
Guarantee or this Agreement) or, subject to the Intercreditor Agreement, release all or substantially all of the Collateral under the Security Documents (except as expressly permitted by the Security Documents or this Agreement), in either case
without the prior written consent of each Lender, or 
 (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 

(ix) affect the rights or duties of, or any Fees or other amounts payable to, any Agent under this Agreement or any other
Credit Document without the prior written consent of such Agent, or 
 (x) decrease the amount or allocation of
any mandatory prepayment to be received by any Term Loan Lender (other than Term Loan Lenders holding Incremental Term Loans) without the written consent of the Required Term Loan Lenders (but not including in such calculation any Incremental Term
Loans), or 
 (xi) (A) decrease the 2014 Term Loan Repayment Amount applicable to the 2014 Term Loans, extend any
scheduled 2014 Term Loan Repayment Date applicable to the 2014 Term Loans or, except as set forth in Section 5.1, Section 5.2(c)(i) or 5.2(c)(ii), decrease the amount or allocation of any mandatory prepayment to be
received by any 2014 Term Loan Lender in a manner disproportionally adverse to the interests of the 2014 Term Loan Lenders in relation to the Term Loan Lenders of any other Class of Term Loans (other than any Class of Incremental Term Loans), in
each case without the written consent of the Required 2014 Term Loan Lenders, or (B) decrease the 2017 Term Loan Repayment Amount applicable to the 2017 Term Loans or extend any scheduled 2017 Term Loan Repayment Date applicable to the 2017
Term Loans, in each case without the written consent of the Required 2017 Term Loan Lenders (it being understood and agreed that any decrease in the amount of 2014 Term Loans or the 2017 Term Loans, as the case may be, on the 2014 Term Loan Maturity
Date or the 2017 Term Loan Maturity Date, respectively, or any extension of the scheduled maturity of the 2014 Term Loans or the 2017 Term Loans, as the case may be, shall, in each case, also be subject to the provisions of
Section 13.1(i)), or 
 (xii) amend, modify or waive any provision of the Posting Facility Fee Letter
without the written consent of the Posting Lead Arranger and the Borrower. 
 Any such waiver and any such amendment, supplement
or modification shall apply equally to each of the affected Lenders and shall be binding upon US Holdings, the Borrower, the applicable Credit Parties, such Lenders, the Administrative Agent, the Posting Agent and all future holders of the affected
Loans or Posting Advances. 

  
 -205-

 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 shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. In connection with the foregoing provisions, the Administrative Agent and, if applicable, the Posting
Agent may, but shall have no obligations to, with the concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of such Lender. 
 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. 

In addition, notwithstanding the foregoing, this Agreement may be amended with the written consent of the Administrative Agent, US
Holdings, the Borrower and the Lenders providing the relevant Replacement Term Loans (as defined below) to permit the refinancing of all outstanding Term Loans of a given Class (“Refinanced Term Loans”) with a replacement term loan
tranche (“Replacement Term Loans”) hereunder; provided that (a) the aggregate principal amount of such Replacement Term Loans shall not exceed the aggregate principal amount of such Refinanced Term Loans, (b) the
Applicable ABR Margin and Applicable LIBOR Margin for such Replacement Term Loans shall not be higher than the Applicable ABR Margin and Applicable LIBOR Margin for such Refinanced Term Loans immediately prior to such refinancing, (c) the

CONTRIBUTORY OR SOLE ORDINARY NEGLIGENCE OF THE INDEMNIFIED PARTY); provided that the Borrower shall have no obligation hereunder to any Agent, any Letter of Credit Issuer or any Lender or any of their respective Related Parties with

 (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 Agent

Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under

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 Section 13.6 shall be treated for purposes
of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with clause (c) of this Section 13.6. 
 (iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at the Administrative Agent’s Office a copy of each Assignment and Acceptance delivered to it and a

pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by US Holdings, the Borrower, the Collateral Agent, the Posting Agent, the

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

 (c) (i) Any Lender may, without the consent of US Holdings, the Borrower, the 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 (including any Existing Revolving Credit Commitments or Extended Revolving Credit 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 continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement
or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and 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 principal amounts of each participant’s interest in the Loans or Posting Advances (or other rights or obligations) held by it (the “Participant Register”). The entries in
the Participant Register shall be conclusive, and such lender shall treat each Person whose name is recorded in the Participant Register as the owner of such Loan, Posting Advance or other obligation hereunder as the owner thereof for all purposes
of this Agreement notwithstanding any notice to the contrary. Any such Participant Register shall be available for inspection by the Administrative Agent, the Posting Agent and the Borrower at any reasonable time and from time to time upon
reasonable prior notice. 
 (d) Any Lender may, without the consent of US Holdings, the Borrower, the Administrative Agent or
the Posting Agent, at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank,
and this Section 13.6 shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto. In order to facilitate such pledge or assignment or for any other reason, the Borrower hereby agrees that, upon request of any Lender at any time and from time to time after
any Borrower has made its initial borrowing hereunder, the Borrower shall provide to such Lender, at the Borrower’s own expense, a promissory note, substantially in the form of Exhibit K-1-A, K-1-B, K-2-A,
K-2-B, K-3-A or K-3-B, evidencing the 2013 Revolving Credit Loans, 2016 Revolving Credit Loans, 2014 Term Loans, 2017 Term Loans, 2014 Deposit L/C Loans and 2017 Deposit L/C Loans, respectively, owing to such Lender. 

  
 -213-

 (e) Subject to Section 13.16, the Borrower authorizes each Lender to disclose to
any Participant, secured creditor of such Lender or assignee (each, a “Transferee”), any prospective Transferee and any prospective direct or indirect contractual counterparties to any swap or 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 without paying any processing fee therefor, assign all or a portion of its
interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and Administrative Agent) providing liquidity and/or credit support to or for the account of such SPV to support the funding or maintenance
of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPV. This
Section 13.6(g) may not be amended without the written consent of the SPV. Notwithstanding anything to the contrary in this Agreement, (x) no SPV shall be entitled to any greater rights under Sections 2.10, 2.11, and
5.4 than its Granting Lender would have been entitled to absent the use of such SPV and (y) each SPV agrees to be subject to the requirements of Sections 2.10, 2.11, and 5.4 as though it were a Lender and has
acquired its interest by assignment pursuant to clause (b) of this Section 13.6.

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

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.

specified in such Credit Document. 
 (b) The Administrative Agent agrees that the receipt of the Communications by the

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

personally liable to the Secured Parties for any amounts payable, or any other Obligation, under the Credit Documents.

 SECTION 14. Posting Facility. 

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

  
 -222-

 (b) On each Computation Date, the Posting Calculation Agent shall determine the amount by
which the MTM Exposure for that Computation Date is greater than or less than the Aggregate Posting Advances Outstanding as of that Computation Date. If such MTM Exposure exceeds such Aggregate Posting Advances Outstanding, then such excess (rounded
up or down to the nearest integral multiple of $100,000) shall be the “Posting Advance Amount” for that Computation Date and the related Posting Advance Date. If such Aggregate Posting Advances Outstanding exceed such MTM Exposure,
then such excess (rounded up or down to the nearest integral multiple of $100,000) shall be the “Posting Repayment Amount” for that Computation Date and the related Posting Repayment Date. 

(c) By no later than 9:00 p.m. (New York time), on each Computation Date (unless it has been prevented from doing so due to a technical
delay or failure (which shall not include a delay or failure that could have been reasonably avoided or for which alternative provision could reasonably have been made) or as a result of a Market Disruption Event), the Posting Calculation Agent
shall notify the Posting Agent and the Borrower of the Posting Advance Amount or Posting Repayment Amount (as applicable) for such Computation Date, which shall be included in, if applicable, the Daily Notice for that date (and may be provided via
email to the addresses of the Borrower and the Posting Agent set forth on Schedule 13.2). 
 (d) If the Daily Notice for
any Computation Date specifies a Posting Repayment Amount, then by no later than 10:00 a.m. (New York time) on the first Business Day after such Daily Notice has been given, the Borrower may advise the Posting Agent that it has elected to repay such
Posting Repayment Amount on the first Business Day following such Computation Date and such Posting Repayment Amount shall be due on such date. 
 14.4. Posting Advances Amounts. 
 (a) Subject to the terms and conditions
herein set forth, each Posting Lender, severally, and not jointly, agrees to make a Posting Advance in Dollars on the Closing Date to the Borrower in an amount equal to such Posting Lender’s Posting Percentage (based on its Posting Commitment)
of the Initial Posting Advance Amount. 
 (b) Subject to the terms and conditions herein set forth, each Posting Lender,
severally, and not jointly, agrees to make a Posting Advance in Dollars on each Posting Advance Date (other than the Closing Date) to the Borrower in an amount equal to such Posting Lender’s Posting Percentage of the Posting Advance Amount for
that Posting Advance Date. 
 (c) No later than 2:00 p.m. (New York time) on each Posting Advance Date, each Posting Lender
will make available its Posting Percentage of each Borrowing of Posting Advances to be made on such date in the manner provided below; provided, further, that on the Closing Date, such funds may be made available at such earlier time
as may be agreed among the Posting Lenders, the Borrower and the Posting Agent. 
 (d) Each Posting Lender shall make available
all amounts it is to make available to the Borrower under any Borrowing of Posting Advances for its applicable Commitments in immediately available funds pursuant to the Payment Instructions (subject to any alternative Payment Instructions or
netting and/or settlement agreements as in effect from time to time), to the Posting Agent, and the Posting Agent will apply such amounts in accordance with the Payment Instructions. Unless the Posting Agent shall have been notified by any Posting
Lender prior to the date of any such Borrowing of such Posting 

  
 -223-

 
Advances that such Lender does not intend to make available to the Posting Agent such Lender’s portion of the Borrowing of such Posting Advances to be made on such date, the Posting Agent
may assume that such Lender has made such amount available to the Posting Agent on such date of such Borrowing, and the Posting Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available
to the Borrower on such date a corresponding amount. If such corresponding amount is not in fact made available to the Posting Agent by such Lender and the Posting Agent has made available such amount to the Borrower, the Posting Agent shall be
entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Posting Agent’s demand therefor the Posting Agent shall promptly notify the Borrower and the Borrower shall
immediately pay such corresponding amount to the Posting Agent in Dollars. The Posting Agent shall also be entitled to recover from such Lender or the Borrower interest on such corresponding amount in respect of each day from the date such
corresponding amount was made available by the Posting Agent to the Borrower to the date such corresponding amount is recovered by the Posting Agent, at a rate per annum equal to (i) if paid by such Lender, the Overnight Rate or (ii) if
paid by the Borrower, the then-applicable rate of interest or fees, calculated in accordance with Section 2.8, for the respective Posting Advances. If such Lender shall repay to the Posting Agent such corresponding amount, such amount
shall constitute such Lender’s portion of such Posting Advance for purposes of this Agreement. 
 (e) Nothing in this
Section 14.4 shall be deemed to relieve any Posting Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender
hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder). 
 (f) Each Posting Advance shall be made by the Posting Lenders pro rata in accordance with their then-applicable Posting Commitments; provided, however, that the failure of any Lender to make
any Posting Advance shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to make any Posting Advance required to be
made by such other Lender). 
 14.5. Posting Repayment Amounts by the Borrower. 

(a) On each Posting Repayment Date, the Borrower shall repay to the Posting Agent, for the benefit of the Posting
Lenders an amount equal to the Posting Repayment Amount for that Posting Repayment Date; provided, however, that at any time that the Posting Lender and the Dealer are not Affiliates, the Borrower shall not be required to repay any Posting
Repayment Amount to any Posting Lender while such Posting Lender is a Defaulting Lender until the earlier of (i) the
60th day following the date such Posting Repayment Amount
is due and (ii) two Business Days following the date upon which such Posting Lender ceases to be a Defaulting Lender. 

(b) On the Posting Facility Maturity Date, the Borrower shall repay to the Lenders the Aggregate Posting Advances Outstanding.

 14.6. Payment Instructions; Netting and/or Settlement Agreements. 

(a) From time to time, the Borrower may establish with the Posting Agent Payment Instructions regarding the making of Posting Advances
hereunder. So long as any such Payment Instruction remains in effect, the terms thereof shall supersede any conflicting terms set forth herein. 

  
 -224-

 (b) From time to time, the Borrower may request that the Posting Agent, on behalf of the
Posting Lenders, enter into netting and/or settlement agreements with the Dealer in order to facilitate the timely payment of amounts payable to or from the Lenders hereunder and to or from the Dealer. So long as any such payment netting and/or
settlement arrangement remains in effect, the terms thereof shall supersede any conflicting terms set forth herein. 
 14.7.
Deemed Transactions. 
 (a) The “Deemed Transactions” shall consist of a portfolio of hypothetical
over-the-counter fixed-for-floating swap transactions under which the Borrower (and its Restricted Subsidiaries) are, on a net volume basis, the “floating price” payor (or has an equivalent position) and which have the net volumes and
fixed prices and relate to the delivery periods in Columns I, II, III and IV of Schedule 1.1(e). 
 (b) The volumes
subject to the Deemed Transactions may, from time to time, be subject to adjustment as follows: 
 (i) with
respect to the monthly volumes referenced in Column III of Schedule 1.1(e) hereto, the Borrower may: 

(A) without any additional fee, (x) increase the volumes in earlier periods if it simultaneously and permanently
decreases by the same amount the volumes in later periods or (y) decrease the volume in any period without increasing the volume in any other period, and 
 (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. 

  
 -225-

 (c) The entries made in the accounts maintained pursuant to clauses (a) and
(b) above shall, to the extent permitted by Applicable Law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any Lender or the Posting Agent to
maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Posting Advances Outstanding in accordance with their terms. 

14.9. Termination and Reduction of Posting Commitments. 
 (a) The Posting Commitments shall terminate automatically at 5:00 p.m. (New York time) on the Posting Facility Maturity Date. 
 (b) Subject to clause (c) below, upon at least ten Business Days’ prior irrevocable written notice to the Posting Agent, the Borrower may at the end of any calendar month, in whole
permanently terminate the Posting Commitments. The Posting Agent shall advise the Posting Lenders of any notice given pursuant to this clause (b). 
 (c) If the Posting Commitments terminate in whole prior to December 31, 2012 for any reason other than as a result of a Lender Default, the Borrower shall pay to the Posting Lead Arranger and
Bookrunner, the Final Termination Maintenance Fee (as defined in the Posting Facility Fee Letter). 
 (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).

prospects of TCEH and each such Guarantor to provide for the extension of the 2013 Revolving Credit Commitments and related 2013 Revolving Credit Loans, and has determined that, in connection with its attempts to extend the maturity dates of the

and the December 2012 Extension Amendment (as defined below); 
 WHEREAS, in light of the foregoing, concurrently
herewith, the Borrower, certain 2013 Revolving Credit Lenders, the Administrative Agent, the Collateral Agent and certain other parties are entering into that certain December 2012 Extension Amendment for the purpose of extending and reclassifying

connection therewith the Borrower has agreed to pay the Extension Fee set forth therein by deeming such Lenders to have made Incremental 2012 Term Loans (as defined below) to the Borrower in an aggregate amount and upon the terms set forth in this
Agreement; 
 WHEREAS, the Borrower has notified the Administrative Agent that it is requesting Incremental Term Loans be
deemed to have been made pursuant to Section 2.14 of the Credit Agreement in an aggregate principal amount of $340,000,000.00; 
 WHEREAS, subject to the terms and conditions of the Credit Agreement, the Borrower may establish Incremental Term Loans by, among other things, entering into one or more Incremental Amendments with
any existing Lender and/or Additional Lender agreeing to 

 
provide (or be deemed to have provided) such Incremental Term Loans (each such Lender or Additional Lender agreeing to provide (or be deemed to have provided) Incremental 2012 Term Loans and any

 (b) No event has occurred and is continuing or would result from the consummation of the proposed Borrowing contemplated hereby that would constitute a Default or an Event of Default.
