any manner and in any order any part of the Collateral or any liability of the Borrower or any other Loan Party to the Secured Parties or the Collateral, or any liability incurred directly or indirectly in respect thereof, to the extent, in all such
cases, that such Person has the right to take and is not prohibited from taking such actions under any or all of the Financing Documents;

Parties to pursue such action (it being understood that the Collateral Agent shall not be required to advise the Required Secured Parties to pursue any such action). Following receipt of any notice that a Event of Default has occurred, the
Collateral Agent may await direction from the Required Secured Parties and will act, or decline to act, as directed by the Required Secured Parties, in the exercise and enforcement of the Collateral Agent’s interests, rights, powers and
remedies in respect of the Collateral or under the Security Documents or applicable law and, following the initiation of such exercise of remedies, the Collateral Agent will act, or decline to act, with respect to the manner of such exercise of
remedies as directed by the Required Secured Parties. Subsequent to the Collateral Agent receiving written notice that any Event of Default has occurred entitling the Collateral Agent to foreclose upon, collect or otherwise enforce the First Liens
then, unless it has been directed to the contrary by the Required Secured Parties, the Collateral Agent in any event may (but will not be obligated to) take all lawful and commercially reasonable actions permitted under the Security Documents that
it may deem necessary or advisable in its reasonable judgment to protect or preserve its interest in the Collateral and the interests, rights, powers and remedies granted or available to the Collateral Agent under, pursuant to or in connection with
the Security Documents. 
 Notwithstanding anything to the contrary contained herein, nothing contained herein shall be construed to impair
the rights of any of the Collateral Agent or the Deposit Letter of Credit Issuer to exercise their rights and remedies in respect of Deposit L/C Collateral, and each of the parties hereto acknowledges and agrees that the Lien and rights of any of
the Collateral Agent or the Deposit Letter of Credit Issuer, to and under Deposit L/C Collateral shall be solely for the benefit of the specific beneficiaries thereof. With respect to the Deposit L/C Loan Collateral, references in this Agreement to
Required Secured Parties shall be deemed references to the Required Deposit L/C Loan Lenders until proceeds from the Deposit L/C Loan Collateral have been applied pursuant to Section 4.1(b) to satisfaction of all priorities except
“last”.

the contrary, (i) the proceeds of any Collateral shall not be applied to the Secured Obligations until each Secured Commodity Hedge Counterparty shall have applied any Other Credit Support to the Secured Obligations owing to such Secured
Commodity Hedge Counterparty, as contemplated by Section 4.4, and (ii) the proceeds of any Collateral (other than Deposit L/C Collateral) shall not be applied to the Deposit L/C Obligations until the full amount of the Deposit L/C
Collateral shall have been applied to the outstanding Deposit L/C Obligations. 
 (c) In calculating the amount of Secured
Obligations owed to any Secured Commodity Hedge Counterparty, Hedge Bank or Cash Management Bank, the applicable Permitted Secured Hedge Amount and/or Termination Payment owed under any Secured Commodity Hedge and Power Sales Agreement, Secured
Hedging Agreement or Secured Cash Management Agreement shall be determined by the relevant Secured Commodity Hedge Counterparty, Hedge Bank or Cash Management Bank in accordance with the terms of the relevant Secured Commodity Hedge and Power Sales
Agreement, Secured Hedging Agreement or Secured Cash Management Agreement, as applicable. In the event that such Secured Commodity Hedge and Power Sales Agreement includes a confirmed transaction that constitutes a Specified Collateral Permitted
Commodity Hedge and Power Sales Agreement, the relevant Secured Commodity Hedge Counterparty shall determine the amount of the Termination Payment that is either then due and payable or would be due and payable under 

  

 22 

 
such Specified Collateral Permitted Commodity Hedge and Power Sales Agreement and shall only setoff and net all Termination Payments that are entitled to the
relevant Specified Hedge Collateral, and such Termination Payments shall be distinct from any other Termination Payment owed to the relevant Secured Commodity Hedge Counterparty under any Secured Commodity Hedge and Power Sales Agreement that does
not constitute a Specified Collateral Permitted Commodity Hedge and Power Sales Agreement or a Specified Collateral Permitted Commodity Hedge and Power Sales Agreement that is secured by different Specified Hedge Collateral. 
 4.4 Application of Other Credit Support. If following the occurrence of an Early Termination Event under any Secured Commodity Hedge and Power
Sales Agreement any Loan Party shall fail to pay any of the Secured Obligations owing under such Secured Commodity Hedge and Power Sales Agreement as and when required thereunder, then each applicable Secured Commodity Hedge Counterparty agrees that
it shall, to the extent permitted under such Secured Commodity Hedge and Power Sales Agreement and the terms of the applicable Other Credit Support, but subject to the occurrence of any Other Credit Support Exception, promptly (i) make a demand
for payment under any Other Credit Support consisting of a Letter of Credit or other letter of credit, cash collateral or a guarantee issued in favor of such Secured Commodity Hedge Counterparty to support the Secured Obligations of the Loan Parties
under such Secured Commodity Hedge and Power Sales Agreement and (ii) apply the proceeds received under any Other Credit Support consisting of a Letter of Credit or other letters of credit, cash collateral or guarantee and any cash consisting
of Other Credit Support pledged in favor of such Secured Commodity Hedge Counterparty to reduce the outstanding amount of such Secured Obligations or enforcement action in connection therewith. 
 4.5 Limitations on Obligations under Secured Commodity Hedge and Power Sales Agreements With Respect to Specified Hedge Collateral.
Notwithstanding anything herein to the contrary in connection with any exercise of remedies, each Secured Commodity Hedge Counterparty that is party to any Specified Collateral Permitted Commodity Hedge and Power Sales Agreement shall only be
entitled to amounts in respect of its Secured Obligations arising thereunder to the extent that proceeds from Collateral being applied pursuant to Section 4.1 constitute the proceeds of Specified Hedge Collateral in respect of such
Specified Collateral Permitted Commodity Hedge and Power Sales Agreement. 
 SECTION 5. Other Agreements. 
 5.1 Releases. (a) Upon the request of any Loan Party in connection with any Disposition of Collateral or any other transaction involving a
proposed release of Collateral or any guarantee (other than in connection with the exercise of any Collateral Agent’s rights and remedies in respect of the Collateral provided for herein) by any Loan Party, in each case to the extent permitted
(if addressed therein, or, otherwise, not prohibited) by the terms of the Credit Agreement and by the terms of the other applicable Financing Documents (including pursuant to Section 10.4 of the Credit Agreement) and in accordance with
the requirements (if any) of the relevant Security Documents, the Collateral Agent will, at the Borrower’s request and sole cost and expense, execute and deliver to such Loan Party such releases and other documents (including UCC termination
statements, reconveyances, customary pay off letters and return of Collateral) as such Loan Party may reasonably request to evidence and effectuate the concurrent release of (A) with respect to any Disposition, any Lien granted under any of the
Security Documents in any Collateral being disposed of in connection with such Disposition, (B) with respect to any Disposition in respect of all of the Capital Stock in, or assets of, such Loan Party, such Loan Party from its Secured
Obligations under the Financing Documents and/or such assets from the Lien granted under any of the Security Documents, or (C) with respect to any Subsidiary Guarantor that is designated as an Unrestricted Subsidiary or where it is otherwise
expressly provided that such Subsidiary is no longer required to be a Guarantor under the Credit Agreement and the other applicable Financing Documents, such Subsidiary from its Secured Obligations under the Financing Documents and/or the assets of
such Subsidiary from the Lien granted under any of the Security Documents. 
  

 23 

 (b) Upon the Discharge of Secured Obligations, all rights to the Collateral shall revert
to the applicable Loan Party, and, upon the written request of the Borrower, the Collateral Agent will, at the Borrower’s expense, (x) promptly cause to be transferred and delivered, without any recourse, warranty or representation
whatsoever, any Collateral and any proceeds received in respect thereof, (y) execute and deliver to the Borrower and the other Loan Parties such UCC termination statements and other documentation as the Borrower or any other Loan Party may
reasonably request to effect the termination and release of the Liens on the Collateral and (z) execute and deliver to the Borrower and the other Loan Parties such other documentation as the Borrower or any other Loan Party may reasonably
request to affect the termination of such Loan Party’s obligations under the Security Documents to which it is a party (other than any such obligation which is intended by its terms to survive the Discharge of Secured Obligations). 

(c) Notwithstanding anything herein to the contrary, the Collateral Agent, on behalf of the Secured Parties, will have the exclusive
right (but subject to the provisions of the Financing Documents) to make determinations regarding the release or disposition of any of the Collateral, without any consultation with, consent of, or notice to, with respect to any of the Collateral
that does not constitute Specified Hedge Collateral under any applicable Specified Collateral Permitted Commodity Hedge and Power Sales Agreement, the Secured Commodity Hedge Counterparty party thereto. 
 (d) Each of the Secured Commodity Hedge Counterparties party to a Specified Collateral Permitted Commodity Hedge and Power Sales Agreement
agrees that it shall promptly, upon the written request of the Borrower, at the Borrower’s expense, execute and deliver to the Borrower and other Loan Parties such documentation as the Borrower may request from time to time to release any Lien
for their benefit in such capacity on any of the Collateral that does not constitute Specified Hedge Collateral under the terms of Specified Collateral Permitted Commodity Hedge and Power Sales Agreement to which it is a party. 
 (e) Subject to any requirements of the Financing Documents, including, without limitation, Section 13.1 of the Credit
Agreement, without further written consent or authorization from any Secured Party, the Collateral Agent shall execute any documents or instruments necessary to release any Collateral or guarantee to the extent the relevant Secured Parties have
consented to such release in accordance with the terms of the Financing Documents. 
 5.2 Amendments to Financing Documents.
(a) Terms of the Secured Obligations and the Financing Documents may be amended, modified, supplemented or extended from time to time, and the aggregate amount of the Secured Obligations may be increased or Refinanced, in each event, without
notice to or consent by any Secured Party that is not a party to such Financing Document and without affecting the provisions hereof, and the Lien priorities provided herein shall not be altered or otherwise affected by any such amendment,
modification, supplement, extension, increase or Refinancing of the Secured Obligations, or any portion thereof; provided, however, that (1) the holders of any such Indebtedness that has been Refinanced under the Loan Documents
(or any agent or trustee therefor) execute and deliver an Accession Agreement to the Collateral Agent in accordance with Section 5.3, and (2) any amendments to any Secured Commodity Hedge and Power Sales Agreements shall be subject
to Section 5.2(c). 
 (b) Notwithstanding anything herein to the contrary, during the continuance of any Event of
Default, to the extent permitted by the applicable Financing Documents, any Secured Party shall be entitled in its reasonable discretion to make payments or advances to the Collateral Agent, any Loan Party or any third party for the purpose of
protecting, preserving or defending the value of the Collateral. 
  

 24 

 (c) Notwithstanding anything to the contrary in the Financing Documents but subject to
Sections 13.1 of the Credit Agreement and Section 5.2(e) below, if the Lenders whose consent is required under Section 13.1 of the Credit Agreement consent to any amendment, modification, termination or waiver of any
provision of the Financing Documents (other than any Secured Commodity Hedge and Power Sales Agreement), or consent to any departure by any Loan Party therefrom, then such amendment, modification, termination, waiver or consent shall apply
automatically to the comparable (if any) provision in any other Financing Document (other than any Secured Commodity Hedge and Power Sales Agreement) without the consent of any other Secured Party; provided that that (A) with respect to
any Secured Commodity Hedge and Power Sales Agreement, any such amendment, modification, termination or waiver shall apply automatically to any Commodity Hedge Covenant under such Secured Commodity Hedge and Power Sales Agreement (except to the
extent that such Secured Commodity Hedge and Power Sales Agreement specifically provides otherwise), and (B) no amendment, modification, termination or waiver shall be made to any provision of any Letter of Credit issued as Other Credit Support
in favor of any Secured Commodity Hedge Counterparty without the prior written consent of such Secured Commodity Hedge Counterparty. 
 (d) Notwithstanding anything to the contrary in this Agreement, and subject to Section 5.2(e) below, in addition the consent of the Borrower, US Holdings and the Subsidiary Guarantors required by Section 9.3(a), the
consent of the Required Secured Parties shall be required for all amendments, modifications, waivers or terminations of this Agreement, other than as permitted pursuant to Section 9.3(b) and (c) hereof. 
 (e) Notwithstanding anything to the contrary in this Agreement or in any of the Security Documents, in any case where the Secured
Commodity Hedge Counterparties would be materially and adversely affected thereby, without the written consent of the Required Commodity Hedge Counterparties and the Required Alternative Commodity Hedge Counterparties (or, if less than all of the
Secured Commodity Hedge Counterparties are so disadvantaged or otherwise discriminated against, the prior written consent of each such Secured Commodity Hedge Counterparty that would be materially and adversely affected thereby), no amendment,
modification, termination or consent in respect of this Agreement or the Security Documents shall be effective if the effect thereof would (directly or indirectly, including through definitional terms used in any of the following): (A) amend
the definition of “Commodity Hedge and Power Sales Secured Obligations”, “Early Termination Event”, “Eligible Hedge Voting Amount”, “Secured Commodity Hedge and Power Sales
Agreement”, “Obligations”, “Secured Parties”, “Floor Amount” (as it applies to such Secured Commodity Hedge Counterparty), “Ordinary Course Settlement Payments”,
“Other Credit Support”, “Other Credit Support Amount”, “Other Credit Support Exception”, “Permitted Secured Hedge Amount”, “Required Secured Parties”,
“Required Commodity Hedge Counterparties”, “Required Alternative Commodity Hedge Counterparties”, “Secured Hedging Agreement” or “Termination Payment”; (B) change the order of
application of proceeds of Collateral and other payments set forth in Section 4.1 or any other provision setting forth a priority of payment in respect of the Secured Obligations (to the extent such provisions relate to a Secured
Commodity Hedge and Power Sales Agreement); or (C) in the case of any Secured Commodity Hedge and Power Sales Agreement, cause the Secured Obligations owed under any such Secured Commodity Hedge and Power Sales Agreement to cease to be secured
on a First Lien, pari passu basis with all other Secured Obligations with respect to Collateral. Notwithstanding the foregoing or anything to the contrary contained herein, no amendment, modification, waiver, supplement, termination or
consent shall be made or given with respect to this 

  

 25 

 
Agreement or any Security Document which has the effect of disproportionately disadvantaging, or otherwise discriminating against, the Secured Commodity
Hedge Counterparties without the prior written consent of the Required Commodity Hedge Counterparties and the Required Alternative Commodity Hedge Counterparties, or, if less than all of the Secured Commodity Hedge Counterparties are so
disadvantaged or otherwise discriminated against, the prior written consent of each such Secured Commodity Hedge Counterparty that would be materially and adversely affected thereby. 
 5.3 Refinancings of Credit Agreement. (a) Subject to the limitations set forth in the applicable Financing Documents (if any), each Loan
Party and each Secured Party acknowledges and agrees that the Credit Agreement may be Refinanced in accordance with this Section 5.3. At any time concurrently with or after the Discharge of Secured Obligations, the Borrower thereafter enters
into a Refinancing of the Credit Agreement (a “Replacement Credit Agreement”) and any related Loan Documents (as defined in the Replacement Credit Agreement), then such Discharge of Secured Obligations shall automatically be deemed
not to have occurred for all purposes of this Agreement (other than with respect to any actions taken as a result of the occurrence of such first Discharge of Secured Obligations) and, the Replacement Credit Agreement and related Loan Documents (as
defined in the Replacement Credit Agreement) and the obligations under such Replacement Credit Agreement and related Loan Documents (as defined in the Replacement Credit Agreement) shall automatically be treated as “Secured Obligations”,
“Loans”, “Posting Advances”, a “Credit Agreement”, and “Loan Documents”, as applicable, and the parties and agents thereto “Lenders”, “Lender Parties” and “Secured Parties”, as
applicable, for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of Collateral set forth herein, and the new administrative agent or trustee thereunder, if any (the “New Administrative
Agent”) shall automatically be treated as the “Administrative Agent” hereunder and the New Collateral Agent (as defined below) shall be appointed hereunder as the “Collateral Agent” for all purposes of this Agreement.
Upon receipt of a notice (the “New Debt Notice”) stating that the Borrower has entered into a new Financing Document, which notice shall include the identify of the new collateral agent (such agent, the “New Collateral
Agent”), the Secured Commodity Hedge Counterparties and all other Secured Parties party hereto at such time shall promptly (a) enter into such documents and agreements (including amendments or supplements to this Agreement) as the
Borrower or such New Collateral Agent shall reasonably request in order to provide to the New Collateral Agent the rights contemplated hereby, in each case consistent in all material respects with the terms of this Agreement and (b) deliver to
the New Collateral Agent any Pledged Collateral held by it together with any necessary endorsements (or otherwise allow the New Collateral Agent to obtain control of such Pledged Collateral). 
 (b) Upon termination of the Credit Agreement, including in connection any amendment and restatement or Refinancing, the Liens securing the
Secured Commodity Hedge Counterparties shall survive. 
 5.4 Notices; Certain Actions. So long as any Secured Obligations remain
outstanding in respect of more than one class of Secured Parties, the following provisions shall apply: 
 (a) Each Secured
Debt Representative hereby agrees to give, pursuant to the terms set forth in the Financing Documents, the Collateral Agent and each other Secured Debt Representative prompt written notice of the occurrence of (i) any Event of Default under
such Person’s Financing Documents, as applicable, of which such Person has written notice, and (ii) acceleration of the maturity of any Secured Obligations under any of the Financing Documents for which it acts as a Secured Debt
Representative wherein such Secured Obligations have been declared to be or have automatically become due and payable prior to the scheduled maturity thereof or termination date thereunder (or similar remedial actions including demands for cash
collateral, have been taken) and setting forth the aggregate amount of Secured Obligations that have been so 

  

 26 

 
accelerated under such Financing Documents, in each case, as soon as practicable after the occurrence thereof (and, in any event, within five Business Days
after the occurrence thereof); provided, however, that the failure to provide such notice shall not limit or impair the rights of the Secured Parties, or the obligations of the Borrower or any other Loan Party, hereunder or under the
other Financing Documents. No Agent shall be deemed to have knowledge or notice of the occurrence of an Event of Default under the Financing Documents to which it is a party until such Agent has received a written notice of such Event of Default
from any other Agent, the Borrower, the other Loan Parties or any other Secured Party for whom such Agent is acting as agent or trustee. 
 (b) The Collateral Agent hereby agrees to give each Secured Debt Representative written notice of the occurrence of an Event of Default following receipt thereof of written notice to it and provide a copy of all other
information provided to it by the Borrower or any other Loan Party under the Security Documents upon request. 
 (c) Each Loan
Party hereby agrees that, at any time and from time to time, at its sole cost and expense, it shall promptly execute and deliver all further agreements, instruments, documents and certificates and take all further action that may be necessary in
order to fully effect the purposes of this Agreement and the Security Documents (including, to the extent required by any Security Document, the delivery of possession of any Collateral represented by certificated securities that hereafter comes
into existence or is acquired in the future to the Collateral Agent as pledgee for the benefit of the Secured Parties) and to enable the Collateral Agent to exercise and enforce their rights and remedies under the Security Documents with respect to
the Collateral or any part thereof. 
 (d) Each of the Secured Commodity Hedge Counterparties agrees that if, at any time and
from time to time, any or all of the Credit Agreement is Refinanced in whole or in part, and in connection with any such Refinancing it is necessary (as reasonably determined by the Borrower) for the parties to enter into one or more new
agreement(s) setting forth the agreements of the parties with respect to certain intercreditor arrangements, guarantees or new collateral or security documents, it shall execute such agreements and documents as the Borrower may reasonably request in
respect thereof to the extent that such agreements and documents are otherwise in accordance with the terms of the Secured Commodity Hedge and Power Sales Agreement to which it is a party (it being acknowledged and agreed that any intercreditor
arrangements, guarantees or new collateral or security documents which contain materially the same provisions as the then existing comparable agreements and that do not have the effect of disproportionately disadvantaging, or otherwise
discriminating against, such Secured Commodity Hedge Counterparty to any greater extent than in the existing comparable agreements, shall be deemed to be acceptable to such Secured Commodity Hedge Counterparty); provided, that,
notwithstanding any provision in this clause to the contrary, no Secured Commodity Hedge Counterparty shall be obligated to execute any intercreditor, collateral, security, guarantee or other document unless any applicable Security Documents secure
the Loan Parties’ obligations to such Secured Commodity Hedge Counterparty on a first lien pari passu basis with the other Secured Obligations as contemplated by this Agreement as in effect on the date hereof. 
 5.5 Letters of Credit; Cash Collateral Accounts; Acknowledgment of Security Interest . (a) Subject to the terms of this
Section 5.5(a), nothing contained in this Agreement shall be construed (i) to impair the rights of any Secured Commodity Hedge Counterparty to exercise its rights and remedies with respect to any cash collateral pledged for its sole
benefit or as a beneficiary under and pursuant to any Other Credit Support issued or pledged in its favor in accordance with the terms of all of the Financing Documents, (ii) to impair the rights of any Commodity Hedging Counterparty to
exercise any of its rights and remedies as an unsecured creditor under any or all Secured Hedging Agreements, subject to Section 3.1(b), or (iii) to impair the rights of any Secured Commodity Hedge Counterparty to exercise its
rights to setoff and net amounts under and among any Secured Hedging Agreement to which 

  

 27 

 
it is a party in accordance with the terms thereof; provided that each Secured Commodity Hedge Counterparty agrees that it shall only exercise such
rights of setoff and netting, in the case of any Secured Commodity Hedge Counterparty, among amounts owing by or to such Secured Commodity Hedge Counterparty under any Secured Hedging Agreements to which it is a party. 
 (b) Notwithstanding anything to the contrary, in the event any Cash Collateral Accounts are established in connection with cash
collateralizing Letters of Credit as contemplated by the definition of Discharge of Secured Obligations or as otherwise contemplated by the Financing Documents, such collateral account shall only be for the benefit of the particular Secured Party or
Secured Parties who issued or have participation interests in such Letters of Credit being cash collateralized. 
 (c) Each of
the Secured Commodity Hedge Counterparties hereby acknowledges and consents to the applicable Loan Party’s collateral assignment (subject to Section 5.5(a)) for the benefit of the Secured Parties of such Loan Party’s rights,
title and interest, in, to and under each of the Secured Commodity Hedge and Power Sales Agreements to which it is a party. 
 5.6
Additional Obligations. (a) Subject to the limitations set forth in the Financing Documents, each Loan Party and each Secured Party acknowledges and agrees that the Collateral may secure additional obligations of the Borrower and the
other Loan Parties in respect of (i) the Refinancing of the Credit Agreement, which shall be subject to Section 5.3, (ii) additional Secured Commodity Hedge and Power Sales Agreements, and (iii) Additional Obligations, in
each case subject to compliance with this Section 5.6. Upon (x) execution and delivery to the Collateral Agent of an Accession Agreement by the Persons to whom the obligations referred to in the immediately precedent sentence are
owed (or by the agent or trustee representing such Person), (y) compliance with the procedures set forth in clause (b) below, and (z) upon satisfaction of all requirements set forth in this Agreement and the Security Documents as to
the confirmation, grant or perfection of the Collateral Agent’s Lien to secure such obligations, such Persons shall become “Secured Parties” hereunder, and the Loan Parties’ obligations to such Persons shall become “Secured
Obligations” hereunder, and the agreements representing such obligations shall become “Financing Documents” hereunder. Each Loan Party and each Secured Party agrees that this Agreement and the applicable Security Documents may be
amended by the Loan Parties and the Collateral Agent without the consent of any Secured Party to the extent necessary or desirable to (i) effectuate the intent of this Section 5.6, (ii) cause the Liens granted thereby to be in
favor of such Persons (to the extent Liens in favor of such Persons are permitted (if addressed therein, or, otherwise, not prohibited) by the terms of the Credit Agreement and by the terms of all of the other applicable Financing Documents) and
(iii) cause such Persons to be treated in the same manner as the other Secured Parties under this Agreement and the other Security Documents. 
 (b) With respect to any additional obligations referred to in Section 5.6(a) above to be secured hereunder after the date hereof, the Borrower will be permitted to designate as an additional holder of Secured
Obligations hereunder each Person who is, or who becomes, the holder of Secured Obligations incurred by the Borrower or a Subsidiary Guarantor in accordance with and as permitted (if addressed therein, or, otherwise, not prohibited) by the terms of
the Credit Agreement and by the terms of the other applicable Financing Documents. The Borrower may effect such designation by delivering to the Collateral Agent, with copies to each Secured Debt Representative, each of the following: 
 (1) a certificate of a Responsible Officer of the Borrower stating that the Borrower or the relevant Subsidiary Guarantor intends, as
applicable, 
  

 28 

 (A) to enter into an additional Secured Commodity Hedge and Power Sales Agreement, and
that such additional obligations will be Secured Obligations and are permitted (if addressed therein, or, otherwise, not prohibited) by the terms of the Credit Agreement and by the terms of the other applicable Financing Documents to be incurred by
the relevant Loan Party and secured by a First Lien equally and ratably with all previously existing and future Security Obligations, or 
 (B) to incur Additional Obligations, which obligations will be Secured Obligations, and are permitted (if addressed therein, or, otherwise, not prohibited) by the terms of the Credit Agreement and by the terms of the
other applicable Financing Documents to be incurred by the relevant Loan Party and secured with a First Lien equally and ratably with all previously existing and future Secured Obligations; and 
 (2) a written notice specifying the name and address of the Secured Debt Representative for such additional obligations for purposes of
this Agreement. 
 (c) Notwithstanding the foregoing, nothing in this Agreement will be construed to allow any Loan Party to
incur additional Indebtedness or grant additional Liens unless in each case otherwise permitted (if addressed therein, or, otherwise, not prohibited) by the terms of the Credit Agreement and by the terms of all other applicable Finance Documents.

 SECTION 6. Insolvency or Liquidation Proceedings. 
 6.1 Finance and Sale Issues. If the Borrower or any other Loan Party shall be subject to any Insolvency or Liquidation Proceeding and the
Collateral Agent (acting at the direction of the Required Lenders) shall desire to permit the use of “Cash Collateral” (as such term is defined in Section 363(a) of the Bankruptcy Code), on which the Collateral Agent or any
other creditor has a Lien (other than Deposit L/C Collateral) or to permit the Borrower or any other Loan Party to obtain financing, whether from the Secured Parties or any other Person under Section 364 of the Bankruptcy Code or any similar
Bankruptcy Law (“DIP Financing”), then the Administrative Agent (on behalf of itself and the Lender Parties), each Secured Commodity Hedge Counterparty, and each other Secured Party agrees that such Secured Party (a) will be
deemed to have consented to, will raise no objection to, nor support any other Person objecting to, the use of such Cash Collateral or such DIP Financing so long as (i) each Secured Party retains the right to object to such use of Cash
Collateral or to the granting of any priming liens over any Collateral if the terms thereof, including the terms of adequate protection (if any) granted to the Secured Parties in connection therewith, do not provide for materially equal treatment to
all Secured Parties, (ii) the DIP Financing does not expressly require the liquidation of any Collateral prior to a default under the DIP Financing documentation and (iii) if any Cash Collateral order contemplates the liquidation of
Collateral, such order provides that the Liens of the Secured Parties will attach to the proceeds of such liquidation equally and ratably, (b) will not request or accept adequate protection or any other relief in connection with the use of such
Cash Collateral or such DIP Financing, and (c) agrees that notice received two calendar days prior to the entry of an order approving such usage of Cash Collateral or approving such DIP Financing shall be adequate notice. 
 6.2 Avoidance Issues. If any Secured Party is required in any Insolvency or Liquidation Proceeding or otherwise to turn over or otherwise pay to
the estate of the Borrower or any other Loan Party for any reason, including without limitation because it was found to be a fraudulent or preferential transfer, any amount paid in respect of the Secured Obligations (a “Recovery”),
whether received as proceeds of security, enforcement of any right of set-off or otherwise, then such Secured Party shall be entitled to a reinstatement of Secured Obligations with respect to all such recovered amounts. In such event (a) the
Discharge of Secured Obligations shall be deemed not to have occurred and (b) if this Agreement shall have been terminated prior to such Recovery, this Agreement shall be reinstated in full force and effect, and such prior termination shall not
diminish, release, discharge, impair or otherwise affect the obligations of the parties hereto from such date of reinstatement. To the extent that such 
  

 29 

 
recovered amount had previously reduced the Eligible Hedge Voting Amount of any Secured Commodity Hedge Counterparty, then upon reinstatement pursuant to
this Section 6.2, such amount shall be added back to such Secured Party’s Eligible Hedge Voting Amount. 
 6.3 Certain
Bankruptcy Rights of Secured Commodity Hedge Counterparties. Notwithstanding anything to the contrary contained herein, but without prejudice to any requirement to distribute Collateral or the proceeds of Collateral among the parties in
accordance with the terms hereof, nothing in this Agreement shall constitute a waiver of, or otherwise impair the exercise of, any rights which the Secured Commodity Hedge Counterparties may have under the following provisions of the Bankruptcy
Code: Section 362(b)(6), (17) and (27), Section 546(e), (g) and (j), Section 556, Section 560 and/or Section 561. 
 SECTION 7. Collateral Agent. 
 7.1 Appointment. (a) Citibank is hereby appointed
Collateral Agent hereunder and under the other Financing Documents and each of the Administrative Agent (for itself and on behalf of each Lender Party), each Secured Commodity Hedge Counterparty and each other Secured Party hereby authorizes
Citibank to act as Collateral Agent in accordance with the terms hereof and the other Security Documents. The Collateral Agent hereby agrees to act in its capacity as such upon the express conditions contained herein and the other Security
Documents, as applicable. In performing its functions and duties hereunder, the Collateral Agent shall act solely as an agent of the Secured Parties and does not assume and shall not be deemed to have assumed any obligation towards or relationship
of agency or trust with or for any Loan Party or any of its Subsidiaries. Each of the Administrative Agent (for itself and on behalf of each Lender Party), each Secured Commodity Hedge Counterparty and each other Secured Party irrevocably authorizes
the Collateral Agent to take such action on their behalf and to exercise such powers, rights and remedies hereunder and under the other Security Documents as are specifically delegated or granted to the Collateral Agent by the terms hereof and
thereof, together with such powers, rights and remedies as are reasonably incidental thereto. The Collateral Agent shall have only those duties and responsibilities that are expressly specified herein and the other Financing Documents. The
Collateral Agent may exercise such powers, rights and remedies and perform such duties by or through its agents or employees. The Collateral Agent shall not have, by reason hereof or any of the other Financing Documents, a fiduciary relationship in
respect of any Secured Party, and nothing herein or in any of the other Financing Documents, expressed or implied, is intended to or shall be so construed as to impose upon the Collateral Agent any obligations in respect hereof or any of the other
Financing Documents except as expressly set forth herein or in the other Security Documents. 
 (b) Except as expressly set
forth in this Section 7, the provisions of this Section 7 are solely for the benefit of the Collateral Agent and the Secured Parties, and no Loan Party shall have any rights as a third party beneficiary of any of the
provisions hereof. 
 7.2 Delegation of Duties. (a) The Collateral Agent may execute any of its duties under this Agreement and
the Financing Documents (including for purposes of holding or enforcing any Lien on the Collateral or any portion thereof granted under the Security Documents or of exercising any rights or remedies thereunder) by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts of its choice concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agent
or attorney-in-fact selected by it with reasonable care. 
 (b) The Collateral Agent may also from time to time, when the
Collateral Agent deems it to be necessary or desirable, appoint one or more trustees, co-trustees, collateral co-agents, collateral subagents or attorneys-in-fact (each, a “Supplemental Collateral Agent”) with respect to all 

  

 30 

 
or any part of the Collateral; provided, however, that no such Supplemental Collateral Agent shall be authorized to take any action with
respect to any Collateral unless and except to the extent expressly authorized in writing by such Collateral Agent. Should any instrument in writing from US Holdings, the Borrower or any other Loan Party be required by any Supplemental Collateral
Agent so appointed by the Collateral Agent to more fully or certainly vest in and confirm to such Supplemental Collateral Agent such rights, powers, privileges and duties, US Holdings or the Borrower shall, or shall cause such Loan Party to,
execute, acknowledge and deliver any and all such instruments promptly upon request by the Collateral Agent. If any Supplemental Collateral Agent, or successor thereto, shall die, become incapable of acting, resign or be removed, all rights, powers,
privileges and duties of such Supplemental Collateral Agent, to the extent permitted by law, shall automatically vest in and be exercised by the Collateral Agent until the appointment of a new Supplemental Collateral Agent. No Agent shall be
responsible for the negligence or misconduct of any agent, attorney-in-fact or Supplemental Collateral Agent that it selects in accordance with the foregoing provisions of this Section 7.2(b) in the absence of such Agent’s gross
negligence or willful misconduct (as determined by a final non-appealable judgment of a court of competent jurisdiction). 
 (c) Any notice, request or other writing given to the Collateral Agent shall be deemed to have been given to each Supplemental Collateral Agent. Every instrument appointing any Supplemental Collateral Agent shall refer to this Agreement and
the conditions of this Section 7.2. 
 (d) Any Supplemental Collateral Agent may at any time appoint the
Collateral Agent as its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf or in its name. 
 7.3 Exculpatory Provisions. (a) The Neither the Collateral Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be taken by any of them under or in connection with this Agreement or any other Financing Document (except for its or such Person’s own gross negligence or willful
misconduct, as determined in the final non-appealable judgment of a court of competent jurisdiction, in connection with its duties expressly set forth herein) or (b) responsible in any manner to any of the Secured Parties for any recitals,
statements, representations or warranties made by any of US Holdings, the Borrower, any other Guarantor, any other Loan Party or any officer thereof contained in this Agreement or any other Financing Document or in any certificate, report, statement
or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Agreement or any other Financing Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Financing Document, or the perfection or priority of any Lien or security interest created or purported to be created under any of the Financing Documents, or for any failure of US Holdings, the Borrower, any other
Guarantor or any other Loan Party to perform its obligations hereunder or thereunder. The Collateral Agent shall not be under any obligation to any Lender Party to ascertain or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Financing Document, or to inspect the properties, books or records of any Loan Party or any Affiliate thereof. The Collateral Agent shall not be under any obligation to the Administrative
Agent, Secured Commodity Hedge Counterparty or any other Secured Party to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Financing Document, or to
inspect the properties, books or records of any Loan Party. 
 (b) The Collateral Agent shall be entitled to refrain from any
act or the taking of any action (including the failure to take an action) in connection herewith or any of the other Security Documents or from the exercise of any power, discretion or authority vested in it hereunder or thereunder unless and until
the Collateral Agent shall have received a direction of the Required 

  

 31 

 
Secured Parties and, upon receipt of such direction the Collateral Agent shall be entitled to act or (where so instructed) refrain from acting, or to
exercise such power, discretion or authority, in accordance with such directions. Without prejudice to the generality of the foregoing; (i) the Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any
communication, instrument or document believed by it to be genuine and correct and to have been signed or sent by the proper Person or Persons, and shall be entitled to rely and shall be protected in relying on opinions and judgments of attorneys
(who may be attorneys for a Loan Party), accounts, experts and other professional advisors selected by it; (ii) no Secured Party shall have any right of action whatsoever against the Collateral Agent as a result of the Collateral Agent acting
or (where so instructed) refraining from acting hereunder or any of the other Security Documents in accordance with a direction of the Required Secured Parties; and (iii) the Collateral Agent shall be fully protected in performing (and is
hereby authorized by the Secured Parties to perform) the ministerial and administrative acts contemplated by or expressly provided in the Collateral Documents. Whenever in the administration of this Agreement the Collateral Agent shall deem it
necessary or desirable that a factual or legal matter be proved or established in connection with the Collateral Agent taking, suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof is herein
specifically prescribed) may be deemed to be conclusively proved or established by a certificate of a Responsible Officer of the Borrower or, if appropriate, from a legal opinion from counsel to the Borrower. 
 (c) Beyond the exercise of reasonable care in the custody thereof and is otherwise specifically set forth herein, the Collateral Agent
shall not have any duty as to any of the Collateral in its possession or control or in the possession or control of any agent or a bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining
thereto and the Collateral Agent shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at an time or times or otherwise perfecting or maintaining the perfection of
any security interest in the Collateral. The Collateral Agent shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier forwarding agency or other agent or
bailee selected by the Collateral Agent in good faith. 
 (d) The Collateral Agent shall be fully justified in failing or
refusing to take any action under this Agreement or under any other Security Document (i) if such action would, in the reasonable opinion of the Collateral Agent, be contrary to applicable law or the terms of this Agreement or (ii) if such
action is not specifically provided for in this Agreement or under any other Collateral Document, it shall not have received a direction of the Required Secured Parties to take such action. 
 7.4 Notice of Event of Default. The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of
Default unless the Collateral Agent has received notice from a Secured Party 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 Collateral Agent receives such a notice, it shall give notice thereof to the other Secured Parties. 
 7.5 Non-Reliance on Collateral
Agent and Other Secured Parties. Each of the Administrative Agent (on behalf of itself and each Lender Party), each Secured Commodity Hedge Counterparty and each other Secured Party expressly acknowledges that neither the Collateral Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Collateral Agent hereinafter taken, including any review of the affairs of US Holdings, the
Borrower, any other Guarantor or any other Loan Party, shall be deemed to constitute any representation or warranty by the Collateral Agent to such Person. Each of the 
  

 32 

 
Administrative Agent (on behalf of itself and each Lender Party), each Secured Commodity Hedge Counterparty and each other Secured Party represents to the
Collateral Agent that it has, independently and without reliance upon the Collateral Agent or any other Secured Party, 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 Loan Party and made its own decision to make its extensions of credit under the Financing Documents
and enter into this Agreement. Each of the Administrative Agent (on behalf of itself and each Lender Party), each Secured Commodity Hedge Counterparty and each other Secured Party also represents that it will, independently and without reliance upon
the Collateral Agent or any other Secured Party, 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 Financing 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 Loan Party. The Collateral Agent shall have no duty or responsibility to provide any Secured Party 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 Loan Party that may come into the possession of the Collateral Agent any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates.

 7.6 Collateral Agent in Individual Capacity. The Collateral 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 Loan Party as though the Collateral Agent were not a Collateral Agent hereunder and under the other Financing Documents. With respect to the
loans made by it, the Collateral Agent shall have the same rights and powers under the Credit Agreement and the other Financing Documents as any Secured Party and may exercise the same as though it were not a Collateral Agent, and the terms
“Lender Party” and “Lender Parties” shall include the Collateral Agent in its individual capacity and under the Loan Documents. 
 7.7 Successor Collateral Agents. The Collateral Agent may at any time give notice of its resignation to the Secured Parties and the Borrower. Upon receipt of any such notice of resignation, the Required Secured Parties shall have the
right, subject to the consent of the Borrower (not to be unreasonably withheld or delayed) so long as no Default under Section 11.1 or 11.5 of the Credit Agreement is continuing, 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 Secured Parties and shall have accepted such appointment within 30 days
after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may on behalf of the Secured Parties, appoint a successor Collateral Agent meeting the qualifications set forth above; provided that if
the Collateral Agent shall notify the Secured Parties and the Borrower that no qualifying person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (x) the retiring
Collateral Agent shall be discharged from its duties and obligations hereunder and under the other Loan 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 Loan
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 Collateral Agent shall instead be made by or to each Secured Party under any of the Loan Documents directly, until such time as the Required Secured Parties 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 a successor Collateral Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as the Collateral Agent hereunder, and upon
the execution and filing or recording of such financing statements, or amendments 
  

 33 

 
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
Secured Parties 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) Collateral Agent, and the retiring Collateral Agent shall be discharged from all of its duties and obligations hereunder or under the other Financing 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 Collateral Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the
retiring Collateral Agent’s resignation hereunder and under the other Financing Documents, the provisions of this Section 7 shall continue in effect for the benefit of such retiring Collateral 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 Collateral Agent was acting as an Collateral Agent. 
 7.8 Security Documents. (a) Agents under Security Documents and Guarantee. Each of the Administrative Agent (on behalf of itself and each Lender Party), each Secured Commodity Hedge Counterparty and
each other Secured Party hereby further authorizes the Collateral Agent, 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 5.1, without further written consent or authorization from any Secured Party, the Collateral Agent may execute any documents or instruments necessary to in connection with a sale or disposition of assets
permitted the Credit Agreement and an other applicable Financing Document, (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 Secured
Parties (or such other Secured Parties as may be required to give such consent) have otherwise consented or (ii) release any Guarantor from the Guarantee, or with respect to which Required Secured Parties (or such other Secured Parties as may
be required to give such consent) have otherwise consented. 
 (b) Right to Realize on Collateral and Enforce
Guarantee. Anything contained in any of the Financing Documents to the contrary notwithstanding, US Holdings, the Borrower, the Collateral Agent 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 Collateral Agent, on behalf of the Secured Parties 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 Secured Party or Secured Parties in its or their respective individual capacities unless Required Secured Parties 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 Secured Obligations as a credit on account of the purchase price for any
collateral payable by the Collateral Agent at such sale or other disposition. 
 7.9 Indemnification. Each Lender Party (through the
Administrative Agent), each Secured Commodity Hedge Counterparty and each other Secured Party agrees to indemnify the Collateral Agent, in its capacity as such (to the extent not reimbursed by the Loan Parties and without limiting the obligation of
the Loan Parties to do so), ratably according to their respective portions of the Secured Obligations in effect on the date on which indemnification is sought, from and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or 
  

 34 

 
disbursements of any kind whatsoever that may at any time occur, be imposed on, incurred by or asserted against the Collateral Agent in any way relating to
or arising out of this Agreement, any of the other Financing 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 the Collateral Agent under
or in connection with any of the foregoing; provided that no Secured Party shall be liable to the Collateral Agent for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the Collateral Agent’s gross negligence or willful misconduct as determined by a final non-appealable judgment of a court of competent jurisdiction (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, further, that no action taken in accordance with the directions of the Required Secured
Parties (or such other number or percentage of the Secured Parties as shall be required) shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 7.9. 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, this Section 7.9 applies whether any
such investigation, litigation or proceeding is brought by any Secured Party or any other Person. Without limitation of the foregoing, each Secured Party shall reimburse the Collateral Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including attorneys’ fees) incurred by the Collateral 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 Financing Document, or any document contemplated by or referred to herein, to the extent that the Collateral Agent is not reimbursed
for such expenses by or on behalf of the Borrower; provided that such reimbursement by the Secured Party shall not affect the Borrower’s continuing reimbursement obligations with respect thereto. If any indemnity furnished to the
Collateral Agent for any purpose shall, in the opinion of the Collateral Agent, be insufficient or become impaired, the Collateral 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 Secured Party to indemnify the Collateral Agent against any liability, obligation, loss, damage, penalty, action, judgment, suit, cost, expense or
disbursement in excess of such Secured Party’s pro rata portion thereof; and provided further, this sentence shall not be deemed to require any Secured Party to indemnify the Collateral Agent against any liability, obligation,
loss, damage, penalty, action, judgment, suit, cost, expense or disbursement resulting from the Collateral Agent’s gross negligence or willful misconduct (as determined by a final non-appealable judgment of a court of competent jurisdiction).
The agreements in this Section 7.9 shall survive the termination of this Agreement. 
 SECTION 8. Reliance; Waivers;
Etc. 
 8.1 Reliance. Other than any reliance on the terms of this Agreement, the Administrative Agent (on behalf of itself and
each Lender Party) acknowledges that it has, independently and without reliance on any Secured Commodity Hedge Counterparty and based on documents and information deemed by it appropriate, made its own credit analysis and decision to enter into such
Financing Documents and be bound by the terms of this Agreement and it will continue to make its own credit decision in taking or not taking any action under the Financing Document or this Agreement. Each Secured Commodity Hedge Counterparty
acknowledges that it has independently and without reliance on the Administrative Agent or any other Secured Party, and based on documents and information deemed by it appropriate, made its own credit analysis and decision to enter into each of the
Financing Documents and be bound by the terms of this Agreement and it will continue to make its own credit decision in taking or not taking any action under the Financing Documents. 
  

 35 

 8.2 No Warranties or Liability. (a) The Administrative Agent (on behalf of itself and each
Lender Party) acknowledges and agrees that no Secured Commodity Hedge Counterparty has made any express or implied representation or warranty, including with respect to the execution, validity, legality, completeness, collectibility or
enforceability of any of any Secured Commodity Hedge and Power Sales Agreement, the ownership of any Collateral or the perfection or priority of any Liens thereon. Except as otherwise expressly provided herein, the Secured Parties will be entitled

Secured Commodity Hedge and Power Sales Agreement in accordance with law and as they may otherwise, in their sole discretion, deem appropriate. 
 8.3 Obligations Unconditional. All rights, interests, agreements and obligations of each of the Collateral Agent, the Administrative Agent and the Secured Parties, respectively, hereunder shall remain in full force and effect
irrespective of: 
 (a) any lack of validity or enforceability of any Financing Documents;

terms of, all or any of the Secured Obligations or any amendment or waiver or other modification, including any increase in the amount thereof, whether by course of conduct or otherwise, of the terms of any Financing Document; 
 (c) except as otherwise expressly set forth in this Agreement, any exchange of any security interest in any Collateral or any other
collateral, or any amendment, waiver or other modification, whether in writing or by course of conduct or otherwise, of all or any of the Secured Obligations or any guarantee thereof; 
 (d) the commencement of any Insolvency or Liquidation Proceeding in respect of the Borrower or any other Loan Party; or

 (b) Notwithstanding the other provisions of this Section 9.3 or any other provision of the Security Documents, the Borrower,

such Security Documents), or grant its consent under any Security Documents, unless and to the extent directed to do so by the Required Secured Parties. If the Collateral Agent determines that direction is needed in the taking of any action, it may

to the commencement of the period for which the Fixed Charge Coverage Ratio is being calculated but prior to or simultaneously with the event for which the calculation of the Fixed Charge Coverage Ratio is made (the “Fixed Charge Coverage
Ratio Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee, redemption, retirement or extinguishment of Indebtedness, or such issuance or

such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the
average daily balance of such Indebtedness during the applicable period except as provided in the first paragraph of this definition. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or
similar rate, a eurocurrency interbank offered rate or other rate shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Borrower may designate.

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).

 2.2. Maximum Number of Borrowings. More than one Borrowing may be incurred on any date, provided that at no time shall there be
outstanding more than 10 Borrowings of LIBOR Loans under this Agreement. 
 2.3. Notice of Borrowing. 
 (a) The Borrower shall give the Administrative Agent at the Administrative Agent’s Office prior to 9:00 a.m. (New York City time) at least
(x) in the case of LIBOR Loans, one Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) of the Borrowing of the Senior Interim Loans and (y) in the case of ABR Loans, one Business Day’s prior
written notice (or telephonic notice promptly confirmed in writing) of the Borrowing of the Senior Interim Loans. Such notice, which shall be in the form of Exhibit A (a “Notice of Borrowing”) shall specify (i) the
aggregate principal amount of the Senior Interim Loans to be borrowed, $2,000,000,000 of which shall be allocated to the Senior Interim Cash Pay Loans (the “Senior Interim Cash Pay Loans Requested Amount”) (such Senior Interim Cash
Pay Loans Requested Amount not to exceed the aggregate Senior Interim Cash Pay Loan Commitments of all Lenders) and $2,500,000,000 of which shall be allocated to the Senior Interim Toggle Loans (the “Senior Interim Toggle Loans Requested
Amount”) (such Senior Interim Toggle Loans Requested Amount not to exceed the aggregate Senior Interim Toggle Loan Commitments of all Lenders), (ii) the date of the Borrowing and (iii) the Interest Period to be initially
applicable thereto. The Administrative Agent shall promptly give each Lender written notice (or telephonic notice promptly confirmed in writing) of the proposed Borrowing of Senior Interim Loans, of such Lender’s proportionate share thereof and
of the other matters covered by the related Notice of Borrowing. 
 (b) Without in any way limiting the obligation of the Borrower to confirm
in writing any notice it may give hereunder by telephone, the Administrative Agent may act prior to receipt of written confirmation without liability upon the basis of such telephonic notice believed by the Administrative Agent in good faith to be
from an Authorized Officer of the Borrower. 
 2.4. Disbursement of Funds. 
 (a) No later than 2:00 p.m. (New York City time) on the date specified in the Notice of Borrowing, each Lender will make available its pro rata
portion, if any, of each Borrowing requested to be made on such date in the manner provided below, provided that such funds may be made available at such earlier time as may be agreed among the Lenders, the Borrower and the Administrative
Agent for the purpose of consummating the Transactions. 
  

 60 

 (b) Each Lender shall make available all amounts it is to fund to the Borrower under the Borrowing for
its applicable Commitments in immediately available funds to the Administrative Agent at the Administrative Agent’s Office, and the Administrative Agent will 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 the Borrowing that such Lender does not intend to make available to
the Administrative Agent its portion of the Borrowing to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on the date of the 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, calculated in
accordance with Section 2.8, for the respective Loans. 
 (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). 
 2.5. Repayment of Loans; Evidence of Debt.

 (a) The Borrower shall repay to the Administrative Agent, for the benefit of the Lenders, on the Term Loan Maturity Date, the
then-outstanding Loans, in Dollars. 
 (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing
the indebtedness of the Borrower to the appropriate lending office of such Lender resulting from each Loan made by such lending office of such Lender from time to time, including the amounts of principal and interest payable and paid to such lending
office of such Lender from time to time under this Agreement. 
 (c) The Administrative Agent shall maintain the Register pursuant to
Section 13.6(b), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount of each Loan made hereunder, the Class and Type of each Loan made and the Interest Period, if
any, applicable thereto, (ii) the amount of any principal (including any PIK Interest Amounts) or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder from the Borrower and each Lender’s share thereof. 
  

 61 

 (d) The entries made in the Register and accounts and subaccounts maintained pursuant to clauses
(b) and (c) of this Section 2.5 shall, to the extent permitted by Applicable Laws, be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided,
however, that the failure of any Lender or the Administrative Agent to maintain such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with
applicable interest) the Loans made to the Borrower by such Lender in accordance with the terms of this Agreement. 
 2.6. Conversions and
Continuations. 
 (a) Subject to the penultimate sentence of this clause (a), (x) the Borrower shall have the option, subject
to Section 2.10, on any Business Day to convert all or a portion equal to at least $5,000,000 of the outstanding principal amount of a Borrowing or Borrowings of one Type into a Borrowing or Borrowings of another Type (provided,
that any conversion of a LIBOR Loan to an ABR Loan shall be effected solely on the last day of the then-applicable Interest Period thereof) 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) 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 its or their sole discretion not to permit such conversion, (ii) 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 and (iii) Borrowings resulting from
conversions pursuant to this Section 2.6 shall be limited in number as provided in Section 2.2. 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 (A) three Business Days’ prior written notice (or telephonic notice promptly confirmed in writing), in the case of a continuation of or conversion to LIBOR Loans
(other than in the case of a notice delivered on the Closing Date pursuant to clause (c), which shall be deemed to be effective on the Closing Date) or (B) one Business Day’s prior written notice (or telephonic notice promptly confirmed in
writing) in the case of a conversion into ABR Loans (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. 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) of this Section 2.6, the Borrower shall
be deemed to have elected to continue such Borrowing of LIBOR Loans as LIBOR Loans with an Interest Period of one month, effective as of the expiration date of such current Interest Period. 
  

 62 

 (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 Loans subject to a Hedging Obligation in respect of interest rates as LIBOR Loans for each Interest Period until the expiration of the
term of such applicable Hedging Obligation. 
 2.7. Pro rata Borrowings. Each Borrowing of Senior Interim Cash Pay Loans under this
Agreement shall be made by the Lenders pro rata on the basis of their then-applicable Senior Interim Cash Pay Loan Commitments. Each Borrowing of Senior Interim Toggle Loans under this Agreement shall be made by the Lenders pro rata on
the basis of their then-applicable Senior Interim Toggle Loan Commitments. It is understood that (a) no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender severally but
not jointly shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder and (b) failure by a Lender to perform any of its obligations under any of
the Loan Documents shall not release any Person from performance of its obligation under any Loan Document. 
 2.8. Interest.

 (a) (i) The unpaid principal amount of each Senior Cash Pay Loan that is an ABR 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 ABR Margin plus the ABR in effect from time to time. 
 (ii) The unpaid principal amount of each Senior Toggle Loan that is an ABR Loan shall bear interest (A) for any Interest Period from
the date of the Borrowing thereof until but not including the fifth anniversary of the Closing Date (the “PIK Interest Termination Date”) at the Borrower’s election: (1) entirely in cash (“Cash Interest”),
(2) entirely by increasing the principal amount of the outstanding Senior Toggle Loans (“PIK Interest”) or (3) 50% as Cash Interest and 50% as PIK Interest (on a pro rata basis among the Lenders holding Senior
Toggle Loans) and (B) for any Interest Period from the PIK Interest Termination Date until the Term Loan Maturity Date (whether by acceleration or otherwise) entirely as Cash Interest. Any Cash Interest shall accrue for each day during such
Interest Period at a rate per annum that shall at all times be the Applicable ABR Margin plus the ABR, in effect from time to time. Any PIK Interest shall accrue for each day during such Interest Period at a rate per annum that
shall at all times be the Applicable ABR Margin plus the ABR in effect from time to time, plus the PIK Margin. 
 (b) (i) The
unpaid principal amount of each Senior Cash Pay Loan that is a 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 effect from time to time. 
  

 63 

 (ii) The unpaid principal amount of each Senior Toggle Loan that is a LIBOR Loan shall
bear interest (A) for any Interest Period from the date of the Borrowing thereof until the PIK Interest Termination Date at the Borrower’s election: (1) entirely as Cash Interest, (2) entirely as PIK Interest or (3) 50% as
Cash Interest and 50% as PIK Interest (on a pro rata basis among the Lenders holding Senior Toggle Loans) and (B) for any Interest Period from the PIK Interest Termination Date until the Term Loan Maturity Date (whether by acceleration
or otherwise) entirely as Cash Interest. Any Cash Interest shall accrue for each day during such Interest Period at a rate per annum that shall at all times be the Applicable LIBOR Margin plus the relevant LIBOR Rate, in effect from
time to time. Any PIK Interest shall accrue for each day during such Interest Period at a rate per annum that shall at all times be the Applicable LIBOR Margin plus the relevant LIBOR Rate in effect from time to time, plus the
PIK Margin. 
 (c) Prior to the PIK Interest Termination Date, the Borrower may elect the form of interest payment with respect to Senior
Toggle Loans for each Interest Period by delivering a notice (the “Interest Election Notice”) five Business Days prior to the commencement of the related Interest Period. Each Interest Election Notice shall include information to
the following effect: (1) the relevant interest payment date; (2) whether interest shall be paid on such interest payment date entirely as Cash Interest, entirely as PIK Interest or 50% as Cash Interest and 50% as PIK Interest; and
(3) if interest shall be paid as PIK Interest, the increase in the principal amount of the Senior Toggle Loans to be effective upon the relevant interest payment date as a result of such payment and the principal amount of the Senior Toggle
Loans to be outstanding as of such interest payment date after giving effect to such payment. If the Borrower does not deliver an Interest Election Notice, the interest on the Senior Toggle Loans will be payable on the related interest payment date
in the form elected pursuant to the Interest Election Notice for the immediately preceding Interest Period. Notwithstanding the foregoing, interest on the Senior Toggle Loans for the first Interest Period will be payable entirely as Cash Interest.

 (d) If all or a portion of (i) the principal amount of any Loan 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 that is (the “Default Rate”) (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 Laws, the rate described in
Section 2.8(a)(i) 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 shall accrue from and including the date of any Borrowing to but excluding the date of any repayment thereof and shall 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 (provided that the first such payment shall be on December 31, 2007), (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, and (iii) in respect of each Loan, (A) on any prepayment, (B) at maturity (whether by acceleration or otherwise) and
(C) after such maturity, on demand. 
  

 64 

 (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 Lenders thereof. Each such determination shall, absent clearly demonstrable error, be final and conclusive and binding on all parties hereto. 
 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
Sections 2.3(a) and 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 month period. 
 Notwithstanding anything to the contrary contained above:

 (a) the initial Interest Period for any Borrowing of LIBOR Loans shall commence on the date of such Borrowing (including the date of any
conversion from a Borrowing of ABR Loans) and each Interest Period occurring thereafter in respect of such Borrowing shall commence on the day on which the next preceding Interest Period expires; 
 (b) if any Interest Period relating to a Borrowing of LIBOR Loans begins on the last Business Day of a calendar month or begins on a day for which there
is no numerically corresponding day in the calendar month at the end of such Interest Period, such Interest Period shall end on the last Business Day of the calendar month at the end of such Interest Period; 
 (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; and 
 (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 Maturity Date of such Loan. 
 2.10. Increased Costs, Illegality, Etc.

 (a) In the event that (x) in the case of clause (i) below, the Administrative 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 that (x) deposits in the principal amounts and currencies of
the Loans comprising such LIBOR Loan Borrowing 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 shall mean do not
exist for ascertaining the applicable interest rate on the basis provided for in the definition of “LIBOR Rate”; or 
  

 65 

 (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 (other than any increase or reduction attributable to (A) Taxes indemnifable under Section 5.4, (B) net income taxes and franchise and excise taxes
(imposed in lieu of net income taxes) imposed on any Agent or Lender or (C) Taxes included under clauses (c) and (d) of the definition of “Excluded Taxes”) because of (x) any change since the date
hereof in any Applicable Laws (or in the interpretation or administration thereof and including the introduction of any new Applicable Laws), 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 has become unlawful as a result of compliance by such Lender in good faith with any Applicable Laws (or would conflict with any such Applicable Laws not having the force of law even though the failure
to comply therewith would not be unlawful), or has become impracticable as a result of a contingency occurring after the date hereof that materially and adversely affects the interbank LIBOR market; 
 then, and in any such event, such Lender (or the Administrative 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 of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of
clause (i) above, LIBOR Loans shall no longer be available until such time as the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist
(which notice the Administrative Agent agrees to give at such time when such circumstances no longer exist), and any Notice of Borrowing or Notice of Conversion or Continuation given by the Borrower with respect to LIBOR Loans that have not yet been
incurred shall be deemed rescinded by the Borrower, (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 Laws. 
  

 66 

 (b) At any time that any LIBOR Loan 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 affected pursuant to Section 2.10(a)(iii) shall) either (x) if the affected LIBOR Loan is then being made pursuant to a
Borrowing, cancel such Borrowing by giving the Administrative Agent 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 is then outstanding, upon at least three Business Days’ notice to the Administrative Agent, require the affected Lender to convert each such LIBOR Loan into an ABR Loan; provided
that if more than one Lender is affected at any time, then all affected Lenders must be treated in the same manner pursuant to this Section 2.10(b). 
 (c) If, after the date hereof, any Change in Law relating to capital adequacy of any Lender or compliance by any Lender or its parent with any Change in Law relating to capital adequacy occurring after the date
hereof, has or would have the effect of reducing the rate of return on such Lender’s or its parent’s or its Affiliate’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below
that which such Lender or its parent or its Affiliate could have achieved but for such Change in Law (taking into consideration such Lender’s or its parent’s policies with respect to capital adequacy), then from time to time, promptly
after demand by such Lender (with a copy to the Administrative Agent), 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 Laws as in effect on the date hereof. Each Lender, upon determining in
good faith that any additional amounts will be payable pursuant to this Section 2.10(c), will give prompt written notice thereof to the Borrower, which notice shall set forth in reasonable detail the basis of the calculation of such
additional amounts, although the failure to give any such notice shall not, subject to Section 2.13, release or diminish the Borrower’s obligations to pay additional amounts pursuant to this Section 2.10(c) upon
receipt of such notice. 
 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 11.15 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. 
  

 67 

 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) 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 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 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 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 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. Permanent Refinancing. 
 (a) On the Interim Loan Conversion Date: 
 (i) all outstanding Senior Interim Cash Pay Loans
shall be automatically converted into term loans (each, a “Senior Cash Pay Term Loan”) having an aggregate principal amount equal to the unpaid principal amount of such Senior Interim Cash Pay Loans, in each case to the extent such
Loans are not repaid in whole or in part in cash on or prior to such date; and 
 (ii) all outstanding Senior Interim Toggle
Loans shall be automatically converted into term loans (each, a “Senior Toggle Term Loan”) having an aggregate principal amount equal to the unpaid principal amount of such Senior Interim Toggle Loans, in each case to the extent
such Loans are not repaid in whole or in part in cash on or prior to such date. 
 (b) (i) On the fifteenth (15th) day of each calendar
month (each, an “Exchange Date”), or if such day is not a Business Day, the preceding Business Day, on or after the Interim Loan Conversion Date, at the option of the applicable Lender, (A) the Senior Cash Pay Term Loans may be
exchanged in whole or in part for one or more Senior Cash Pay Notes issued pursuant to the Senior Refinancing Indenture having an aggregate principal amount equal to the unpaid principal amount of such Senior Cash Pay Term Loans and (B) the
Senior Toggle Term Loans may be exchanged in whole or in part for one or more Senior Toggle Notes issued pursuant to the Senior Refinancing Indenture having an aggregate principal amount equal to the unpaid principal amount of such Senior Toggle
Term Loans; provided, however, that the Borrower shall not be required to issue Senior Cash Pay Notes or Senior Toggle Notes, as the case may be, until the Borrower shall have received requests to issue at least $150,000,000 in
aggregate principal amount of each of Senior Cash Pay Notes and Senior Toggle Notes and that the amount of Senior Term Loans exchanged for Senior Notes must be in excess of $1,000,000 in principal amount. 
  

 68 

 (ii) Such Lender shall provide the Borrower prior irrevocable written notice of such
election (each such notice, an “Exchange Notice”), substantially in the form of Exhibit E-1 or Exhibit E-2, as applicable, at least five Business Days prior to the date of exchange. The Exchange Notice shall specify
the principal amount of Senior Term Loans to be exchanged (which shall be at least $1,000,000 and integral multiples in excess thereof for each Class of Loans or the entire remaining aggregate principal amount of Loans of such Lender) and, subject
to the terms of the Senior Refinancing Indenture, the name of the proposed registered holder and the amount of each Senior Note requested. Senior Term Loans exchanged for Senior Notes pursuant to this Section 2.14 shall be deemed repaid
and canceled, and the Senior Notes so issued shall be governed by and construed in accordance with the provisions of the Senior Refinancing Indenture. The Senior Notes shall be issued in the form set forth in the Senior Refinancing Indenture.

 (iii) As more particularly provided in the Senior Refinancing Indenture, (A) Senior Cash Pay Notes issued pursuant to
the Senior Refinancing Indenture shall bear interest at the rate applicable to Senior Cash Pay Term Loans (unless a Lender shall elect to have the interest rate fixed at the rate applicable to Senior Cash Pay Term Loans in effect on the date of such
exchange if necessary to effect an actual bona fide sale of such Senior Cash Pay Notes on such date to a third party that is not an Affiliate of such Lender), (B) Senior Toggle Notes issued pursuant to the Senior Refinancing Indenture shall
bear interest at the rate applicable to Senior Toggle Term Loans (unless a Lender shall elect to have the interest rate fixed at the rate applicable to Senior Toggle Term Loans in effect on the date of such exchange if necessary to effect an actual
bona fide sale of such Senior Toggle Notes on such date to a third party that is not an Affiliate of such Lender), and (C) Senior Notes issued pursuant to the Senior Refinancing Indenture (I) shall mature on October 15, 2017 and
(I) shall be redeemable as set forth in the Senior Refinancing Indenture and the applicable form of Senior Notes attached thereto. 
 (iv) Not later than five Business Days after the Exchange Date following delivery of any Exchange Notice, the Borrower shall (A) deliver a written notice to the trustee under the Senior Refinancing Indenture (the
“Trustee”), directing such Trustee to authenticate and deliver Senior Cash Pay Notes and/or Senior Toggle Notes as specified in the Exchange Notice and (B) use all commercially reasonable efforts to effect delivery of such
Senior Cash Pay Notes and/or Senior Toggle Notes to the requesting Lender. 
 (c) The Borrower agrees that as a condition to the
effectiveness of the exchange of Senior Term Loans for Senior Notes: 
 (i) The Borrower shall have selected a bank or trust
company reasonably acceptable to the Lenders to act as Trustee. 
 (ii) The Borrower shall have issued the Senior Notes
pursuant to the Senior Refinancing Indenture substantially in the applicable form set forth therein, and the Borrower and each Guarantor shall have executed and delivered the Senior Refinancing Indenture. 
  

 69 

 (iii) The Borrower and each Guarantor shall have provided to the Administrative Agent
copies of resolutions of its Board of Directors approving the execution and delivery of the Senior Refinancing Indenture and, in the case of the Borrower, the issuance of the Senior Notes, together with a customary certificate of the secretary of
the Borrower or such Guarantor certifying such resolutions. 
 (iv) The Borrower and each Guarantor shall have executed and
delivered the Senior Refinancing Registration Rights Agreement. 
 (v) The Borrower and each Guarantor shall have provided to
the Lenders copies of resolutions of its Board of Directors approving the execution and delivery of the Senior Refinancing Registration Rights Agreement, together with a customary certificate of the secretary of the Borrower or such Guarantor
certifying such resolutions.

validity and enforceability of the Senior Refinancing Indenture and the Senior Refinancing Registration Rights Agreement). 
 (d) If the
foregoing conditions set forth in Section 2.14(c) are not satisfied on the Interim Loan Conversion Date, then the Lenders shall retain all of their rights and remedies with respect to the Senior Term Loans pursuant to this Agreement
until such conditions are satisfied and the Senior Term Loans are so exchanged for Senior Notes. The Borrower agrees to satisfy the conditions set forth in Section 2.14(c) no later than ten Business Days after receipt of the first

 (e) Nothing in this Section 2.14 shall prevent or limit the ability of the Borrower from repaying or
refinancing, the Loans in any other manner not otherwise prohibited by this Agreement. 
 (f) It is understood and agreed that the Senior

 SECTION 5. Payments. 
 5.1. Voluntary Prepayments. 
 (a) The Borrower shall have the right to prepay Loans, without premium
or penalty, in whole or in part, from time to time on the following terms and conditions: (a) the Borrower shall give the Administrative Agent at the Administrative Agent’s Office written notice (or telephonic notice promptly confirmed in
writing) of its intent to make such prepayment, the amount of such prepayment and, in the case of LIBOR Loans, the specific Borrowing(s) pursuant to which made, which notice shall be given by the Borrower no later than 1:00 p.m. (New York City time)
(i) in the case of LIBOR Loans, three Business Days prior to or (ii) in the case of ABR Loans, one Business Day prior to, the date of such prepayment and shall promptly be transmitted by the Administrative Agent to each of the Lenders
(b) each partial prepayment of (i) any Borrowing of LIBOR Loans shall be in a minimum amount of $5,000,000 and in multiples of $1,000,000 in excess thereof and (ii) any ABR Loans shall be in a minimum amount of $1,000,000 and in
multiples of $100,000 in excess thereof, provided that no partial prepayment of LIBOR Loans made pursuant to a single Borrowing shall reduce the outstanding LIBOR Loans made pursuant to such Borrowing to an amount less than $5,000,000 and
(c) any prepayment of LIBOR Loans pursuant to this Section 5.1 on any day other than the last day of an Interest Period applicable thereto shall be subject to compliance by the Borrower with the applicable provisions of
Section 2.11. Each prepayment in respect of any Loans pursuant to this Section 5.1 shall be applied to the Loans on a pro rata basis based on the aggregate principal amount of Loans outstanding at such time. At the
Borrower’s election in connection with any prepayment pursuant to this Section 5.1, such prepayment shall not be applied to any Loan of a Defaulting Lender. 
 (b) At the end of any “accrual period” (as defined in Section 1272(a)(5) of the Code) ending after October 10, 2012 (each, an
“Optional Interest Repayment Date”), the Borrower may pay in cash, without duplication, all accrued and unpaid interest, if any and all accrued but unpaid “original issue discount” (as defined in
Section 1273(a)(1) of the Code) on each Senior Toggle Term Loan and/or Senior Toggle Note then outstanding up to the Optional Interest Repayment Amount, minus $50,000,000 (each such redemption, an “Optional Interest
Repayment”). The “Optional Interest Repayment Amount” shall mean, as of each Optional Interest Repayment Date, the excess, if any, of (i) the aggregate amount of accrued and unpaid interest and all accrued but unpaid
“original issue discount” (as defined in Section 1273(a)(1) of the Code) with respect to the applicable Senior Toggle Term Loan or Senior Toggle Note, over (ii) an amount equal to the product of (A) the “issue
price” (as defined in Sections 1273(b) and 1274(a) of the Code) of the applicable Senior Toggle Term Loan or Senior Toggle Note multiplied by (B) the “yield to maturity” (as defined in the Treasury Regulation
Section 1.1272-1(b)(1)(i)) of such Senior Toggle Term Loan or Senior Toggle Note. 
 5.2. Mandatory Prepayments. 
 (a) Prepayments. (i) Prior to the Interim Loan Conversion Date on each occasion that a Debt Incurrence Prepayment Event occurs, the Borrower
shall, (within three Business Days after its receipt of the Net Cash Proceeds of a Debt Incurrence Prepayment Event, cause to be prepaid, in accordance with clause (c) below Loans with principal amount equal to 

  

 71 

 
100% of the Net Cash Proceeds from such Debt Incurrence Prepayment Event; provided that the Borrower may, to the extent required by the Senior Secured Credit
Agreement, apply such Net Cash Proceeds to prepay, repay or repurchase Indebtedness outstanding under the Senior Secured Credit Agreement within three Business Days after receipt thereof, prior to the application of such Net Cash Proceeds to prepay
Loans. 
 (ii) At any time on or after the Interim Loan Conversion Date, the provisions of Section 5.2(a)(i) shall no longer
be operative. 
 (b) [Reserved]. 
 (c) Application of Amounts. Subject to Section 5.2(h), each prepayment of Senior Interim Loans required by Section 5.2(a)(i) the proceeds of which are derived from the sale of Senior
Cash Pay Notes shall be applied on a pro rata basis to the aggregate principal amount of outstanding Senior Cash Pay Loans and the proceeds of which are derived from the sale of Senior Toggle Notes shall be applied on a pro rata basis to the
aggregate principal amount of outstanding Senior Toggle Loans; provided, however, that if US Holdings is the issuer of the Indebtedness in respect of such Debt Incurrence Prepayment Event, the applicable of the Net Cash Proceeds shall
be applied on a pro rata basis to the aggregate principal amount of outstanding Loans and the aggregate principal amount of outstanding TCEH Senior Interim Loans. Subject to Section 5.2(h), with respect to each such prepayment,
the Borrower will, not later than the date specified in the applicable clause of Section 5.2(a)(i) for making such prepayment, give the Administrative Agent telephonic notice (promptly confirmed in writing) requesting that the
Administrative Agent provide notice of such prepayment to each Lender. 
 (d) Application to Loans. With respect to each prepayment of
Loans required by Section 5.2(a) (but subject to clause (c)) or required or permitted by Section 9.8(b) the Borrower may, if applicable, designate the Types of Loans that are to be prepaid and the specific Borrowing(s)
pursuant to which made. 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. 
 (e) [Reserved]. 
 (f) LIBOR Interest Periods. In lieu of making any payment pursuant to this Section 5.2 or pursuant to Section 9.8(b) 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. 
  

 72 

 (g) [Reserved] 
 (h) Notification of Mandatory Prepayment. The Borrower shall notify the Administrative Agent in writing of any mandatory prepayment of Loans required to be made pursuant to Section 5.2(a), in each
case at least three Business Days prior to the date of such prepayment. Each such notice shall specify the date of such prepayment and provide a reasonably detailed calculation of the amount of such prepayment. The Administrative Agent will
promptly notify each Lender holding Loans of the Class required to be prepaid in accordance with Section 5.2(c) of the contents of the Borrower’s prepayment notice and of such Lender’s pro rata share of the prepayment.

 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 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 Loan 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 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 Loan 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 shall be required by Applicable Laws 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 or any Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions 

  

 73 

 
or withholdings been made, (ii) the Borrower or such Guarantor or the Administrative Agent, shall make such deductions or withholdings and
(iii) the Borrower or such Guarantor or the Administrative Agent shall timely pay the full amount deducted or withheld to the relevant Government Authority within the time allowed and in accordance with Applicable Laws. 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 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 each 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 Government Authority). 
 (c) The Borrower shall indemnify and hold harmless the Administrative 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 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 Loan 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 Government Authority. A certificate setting forth reasonable detail as to the amount of such payment or liability delivered to the Borrower
by a Lender or the Administrative 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 Loan Document shall, to the extent it is legally able to do so, deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by Applicable Laws or reasonably
requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by Applicable Laws 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, shall deliver such other
documentation prescribed by Applicable Laws or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or
information reporting requirements. 
  

 74 

 (e) Each Non-U.S. Lender with respect to any Loan made to the Borrower shall, to the extent it is legally
entitled to do so: 
 (i) deliver to the Borrower and the Administrative 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 J 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 Loan
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 Loan Documents (for example, in the case of a typical
participation or where a Non-U.S. Lender is a pass through entity) Internal Revenue Service Form W-8IMY and all necessary attachments (including the forms described in clauses (x) and (y) above, as required); and 

(ii) deliver to the Borrower and the Administrative Agent 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. 
 (f) If any Lender or the Administrative 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 or the Administrative Agent, as the case may be, is attributable to such
payment made by the Borrower, then the Lender or the Administrative Agent, as the case may be, shall reimburse the Borrower for such amount (net of all out-of-pocket expenses of such Lender or the Administrative Agent, as the case may be, and
without interest other than any interest received thereon from the relevant Government Authority with respect to such refund) as the Lender or the Administrative 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 or the Administrative Agent, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Government Authority) to the Lender or the
Administrative Agent in the event the Lender or the Administrative Agent is required to repay such refund to such Government Authority. A Lender or the Administrative 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 nor the Administrative Agent shall be obliged to disclose any information regarding its tax affairs or computations to any Loan Party in
connection with this clause (f) or any other provision of this Section 5.4. 
  

 75 

 (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 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 two United States
Internal Revenue Service Forms W-9 (or substitute or successor form), properly completed and duly executed, certifying that such Lender or Agent is exempt from United States backup withholding (i) on or prior to the Closing Date (or on or prior
to the date it becomes a party to this Agreement), (ii) on or before the date that such form expires or becomes obsolete, (iii) after the occurrence of a change in the Agent’s or Lender’s circumstances requiring a change in the
most recent form previously delivered by it to the Borrower and the Administrative Agent, and (iv) from time to time thereafter if reasonably requested by the Borrower or the Administrative Agent. 
 (i) The agreements in this Section 5.4 shall survive the termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder. 
 5.5. Computations of Interest. 
 (a) (i) Interest on LIBOR Loans shall be calculated on the basis of a 360-day year for the actual days elapsed and (ii) interest on ABR Loans 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. 
 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 Laws. 
 (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. 
  

 76 

 (c) Adjustment if Any Payment Exceeds Lawful Rate. If any provision of this Agreement or any of
the other Loan 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 Laws, 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 Laws, 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) 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 Laws, 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.

constitutes the legal, valid and binding obligation of such Loan 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). 
  

 79 

 8.3. No Violation. Neither the execution, delivery or performance by any Loan Party of the Loan
Documents to which it is a party nor the compliance with the terms and provisions thereof nor the consummation of the Merger and the other transactions contemplated hereby and thereby will (a) contravene any applicable provision of any material
Applicable Laws (including any 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

(c) violate any provision of the Organizational Documents of US Holdings, the Borrower or any of the Restricted Subsidiaries. 
 8.4.
Litigation. Except as set forth on Schedule 8.4, there are no actions, suits or proceedings (including Environmental Claims) pending or, to the knowledge of the Borrower, threatened with respect to the Borrower or any of the Restricted
Subsidiaries that could reasonably be expected to result in a Material Adverse Effect. 
 8.5. Margin Regulations. Neither the making
of any Loan hereunder nor the use of the proceeds thereof will violate the provisions of Regulation T, U or X of the Board. 
 8.6.
Governmental Approvals. The execution, delivery and performance of the Acquisition Agreement or any Loan Document does not require any consent or approval of, registration or filing with, or other action by, any Government Authority, except

respective authorized representatives to the Administrative Agent, any Joint Lead Arranger and Bookrunner, and/or any Lender on or before the Closing Date (including all such information and data contained in the Loan Documents) for purposes of or
in connection with this Agreement or any transaction contemplated herein contained any untrue statement of any material fact or omitted to state any material fact necessary to make such information and data (taken as a whole) not materially
misleading at

Section 8.8(a), such factual information and data shall not include projections or estimates (including financial estimates, forecasts and other forward-looking information) and information of a general economic or general industry
nature.

respects on a pro forma basis the estimated financial position of the Borrower and its consolidated Subsidiaries as at June 30, 2007 and their estimated results of operations for the period covered thereby. The financial statements

covenants or the performance of this Agreement; and the Borrower and each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenant that they shall not, by resort to

Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired;

referred to in clauses (1) through (11) of this Section 9.6(b); provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in
the good faith judgment of the Borrower, no more restrictive with respect to such encumbrance and other restrictions taken as a whole than those prior to such amendment, modification, restatement, renewal, increase, supplement, refunding,
replacement or refinancing; 
 (13) restrictions created in connection with any Receivables Facility for the benefit of the

 (7) Indebtedness of the Borrower to a Restricted Subsidiary; provided that any such Indebtedness owing to a Restricted Subsidiary

in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred Stock (except to the Borrower or another of its Restricted Subsidiaries) shall be deemed in each case to be an

(including reasonable tender premiums), defeasance costs and fees in connection therewith (the “Refinancing Indebtedness”) prior to its respective maturity; provided, however, that such Refinancing Indebtedness:

 (a) has a Weighted Average Life to Maturity at the time such Refinancing Indebtedness is incurred which is not less than
the remaining Weighted Average Life to Maturity of the Indebtedness, Disqualified Stock or Preferred Stock being refunded or refinanced,

Borrower to the extent described in clause (4) of Section 9.5(b) hereof. 
 (c) For purposes of determining
compliance with this Section 9.7: 
 (x) in the event that an item of Indebtedness, Disqualified Stock or
Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of permitted Indebtedness, Disqualified Stock or Preferred Stock described in clauses (b)(1) through (19) of this
Section 9.7(b) or is entitled to be incurred pursuant to Section 9.7(a) hereof, the Borrower, in its sole discretion, will classify or reclassify such item of Indebtedness, Disqualified Stock or Preferred Stock (or any
portion thereof) and shall only be required to include the amount and type of such Indebtedness, Disqualified Stock or Preferred Stock in one of the above clauses (b)(1) through (19) of this Section 9.7(b) or under
Section 9.7(a) hereof; and 
 (y) at the time of incurrence, the Borrower will be entitled to divide and classify
an item of Indebtedness in more than one of the types of Indebtedness described in Sections 9.7(a) and 9.7(b) hereof; 
 provided that all Indebtedness outstanding under the Credit Facilities on the Closing Date shall be treated as incurred on the Closing Date under clause (1) of Section 9.7(b) hereof. 
 (d) Accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness, Disqualified
Stock or Preferred Stock shall not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 9.7. 
 (e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S.
dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed,
in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other 

  

 101 

 
Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if
calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not
exceed the principal amount of such Indebtedness being refinanced. 
 The principal amount of any Indebtedness incurred to refinance other
Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on
the date of such refinancing. 
 (f) Notwithstanding anything to the contrary, (i) the Borrower shall not, and shall not
permit any Guarantor to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of the Borrower or such Guarantor, as the case may be, unless such
Indebtedness is expressly subordinated in right of payment to the Loans or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Borrower or such Guarantor, as the case
may be and (ii)(a) no unsecured Indebtedness shall be treated as subordinated or junior to Secured Indebtedness merely because it is unsecured or (b) no Senior Indebtedness shall be treated as subordinated or junior to any other Senior
Indebtedness merely because it has a junior priority with respect to the same collateral. 
 9.8. Asset Sales. 
 (a) The Borrower shall not, and shall not permit any of its Restricted Subsidiaries to consummate, directly or indirectly, an Asset Sale, unless:

 (1) the Borrower or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale
at least equal to the fair market value (as determined in good faith by the Borrower) of the assets sold or otherwise disposed of; and 
 (2) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by the Borrower or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents;
provided that the amount of: 
 (A) any liabilities (as shown on the Borrower’s or such Restricted
Subsidiary’s most recent balance sheet or in the footnotes thereto) of the Borrower or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Loans or that are owed to the Borrower or an Affiliate of the
Borrower, that are assumed by the transferee of any such assets and for which the Borrower and all of its Restricted Subsidiaries have been validly released by all applicable creditors in writing, 
  

 102 

 (B) any securities received by the Borrower or such Restricted Subsidiary from such
transferee that are converted by the Borrower or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the closing of such Asset Sale, and 
 (C) any Designated Non-Cash Consideration received by the Borrower or such Restricted Subsidiary in such Asset Sale having an aggregate
fair market value, taken together with all other Designated Non-Cash Consideration received pursuant to this clause (C) that is at that time outstanding, not to exceed (x) prior to the Interim Loan Conversion Date, 1.5% of Total
Assets at the time of the receipt of such Designated Non-Cash Consideration and (y) thereafter, 5% of Total Assets at the time of the receipt of such Designated Non-cash Consideration, in each case with the fair market value of each item of
Designated Non-Cash Consideration being measured at the time received and without giving effect to subsequent changes in value, 
 shall be
deemed to be cash for purposes of this provision and for no other purpose. 
 (b) Within 450 days after the receipt of any Net Asset Sale
Proceeds, the Borrower or such Restricted Subsidiary, at its option, may apply such Net Asset Sale Proceeds, 
 (1) to
permanently reduce: 
 (A) Obligations under Senior Indebtedness which is Secured Indebtedness permitted by this Agreement,
and to correspondingly reduce commitments with respect thereto; 
 (B) Obligations under (i) this Agreement, or
(ii) other Senior Indebtedness (and to correspondingly reduce commitments with respect thereto); provided that to the extent the Borrower or such Guarantor reduces or makes an offer to prepay, as applicable, Obligations under Senior
Indebtedness other than the Loans, including by making an offer in accordance with the procedures set forth in Section 4.10 of the Senior Refinancing Indenture (such provisions of which are incorporated herein for purposes of this
Section 9.8), the Borrower shall equally and ratably reduce or make an offer to prepay, as applicable, the Loans at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of the Loans
that would otherwise be prepaid; 
 (C) after the Interim Loan Conversion Date, Obligations under the Existing Notes which
have a final maturity date (as in effect on the Closing Date) on or prior to October 15, 2017; provided that, at the time of, and after giving effect to, such repurchase, redemption or defeasance, the aggregate amount of Net Asset Sale
Proceeds used to repurchase, redeem or defease Existing Notes pursuant to this subclause (C) following the Closing Date shall not exceed 3.5% of Total Assets at such time; or 
 (D) Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Borrower or another Restricted
Subsidiary (or any Affiliate thereof); 
  

 103 

 provided that, if an offer to purchase any Indebtedness of TCEH or any of its Restricted Subsidiaries is made in
accordance with the terms of such Indebtedness, the obligation to permanently reduce Indebtedness of a Restricted Subsidiary will be deemed to be satisfied to the extent of the amount of the offer, whether or not accepted by the holders thereof, and
no Net Asset Sale Proceeds in the amount of such offer will be deemed to exist following such offer; 
 (2) to make
(a) an Investment in any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in the Borrower or another of its Restricted Subsidiaries, as the case may be,
owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) capital expenditures or (c) acquisitions of other assets, in each of clauses (a) through (c), that are used or
useful in a Similar Business; or 
 (3) to make an Investment in (a) any one or more businesses; provided that
such Investment in any business is in the form of the acquisition of Capital Stock and results in the Borrower or another of its Restricted Subsidiaries, as the case may be, owning an amount of the Capital Stock of such business such that it
constitutes a Restricted Subsidiary, (b) properties or (c) acquisitions of other assets, in each of clauses (a) through (c), that replace the businesses, properties and/or assets that are the subject of such Asset Sale;

 provided that, in the case of clauses (2) and (3) above, a binding commitment shall be treated as a permitted application
of the Net Asset Sale Proceeds from the date of such commitment so long as the Borrower or such other Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Asset Sale Proceeds will be applied to satisfy such
commitment within 180 days of such commitment (an “Acceptable Commitment”) (and reinvest within the later of 450 days from the date of receipt of Net Asset Sale Proceeds and 180 days of receipt of such commitment), and, in the event
any Acceptable Commitment is later cancelled or terminated for any reason before the Net Asset Sale Proceeds are applied in connection therewith, the Borrower or such Restricted Subsidiary enters into another Acceptable Commitment (a “Second
Commitment”) within the later of (a) 180 days of such cancellation or termination or (b) the initial 450-day period; provided, further, that if any Second Commitment is later cancelled or terminated for any reason
before such Net Asset Sale Proceeds are applied, then such Net Asset Sale Proceeds shall constitute Excess Proceeds. 
 Notwithstanding the
preceding paragraph, in the event that regulatory approval is necessary for an asset or investment, or replacement, repair or restoration on any asset or investment, then the Borrower or any Restricted Subsidiary shall have an additional 365 days to
apply the Net Asset Sale Proceeds from such Asset Sale in accordance with the preceding paragraph. 
 (c) Any Net Asset Sale Proceeds from
Asset Sales that are not invested or applied as provided and within the time period set forth in Section 9.8(b) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds
$200,000,000, the Borrower shall make an offer to all Lenders or holders of the Senior Notes, as applicable, and, if required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale
Offer”), to purchase the maximum aggregate 

  

 104 

 
principal amount of the Loans or Senior Notes, as applicable, and such Senior Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 in
excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest, to the date fixed for the closing of such offer, in accordance
with the procedures set forth in this Agreement. The Borrower will commence an Asset Sale Offer with respect to Excess Proceeds within 10 Business Days after the date that Excess Proceeds exceed $200,000,000 by mailing the notice required pursuant
to the terms of this Agreement or the Senior Refinancing Indenture, as applicable, with a copy to the Administrative Agent. 
 To the extent
that the aggregate amount of Loans or Senior Notes, as applicable, and any other Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Borrower may, after the Interim Loan Conversion Date, use any
remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in this Agreement or the Senior Refinancing Indenture, as applicable. If the aggregate principal amount of Loans or Senior Notes, as applicable, or the
Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Administrative Agent shall select the Loans or Senior Notes, as applicable, and such other Senior Indebtedness to be purchased on a pro rata basis
based on the accreted value or principal amount of the Loans or Senior Notes, as applicable, or such Senior Indebtedness which have been accepted for repayment by the applicable Lender. Additionally, the Borrower may, at its option, make an Asset
Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale; provided that such Asset Sale Offer shall be in an aggregate amount of not less than $25,000,000. Upon consummation of such Asset Sale Offer, any
Net Asset Sale Proceeds not required to be used to purchase Loans or Senior Notes, as applicable, shall not be deemed Excess Proceeds. 
 (d)
Pending the final application of any Net Asset Sale Proceeds pursuant to this Section 9.8, the holder of such Net Asset Sale Proceeds may apply such Net Asset Sale Proceeds temporarily to reduce Indebtedness outstanding under a revolving
credit facility or otherwise invest such Net Asset Sale Proceeds in any manner not prohibited by this Agreement. 
 9.9. Transactions with
Affiliates. 
 (a) The Borrower shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell,
lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of the Borrower (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $25,000,000, unless: 
 (1) such Affiliate Transaction is on terms that are not materially less favorable to the Borrower or its relevant Restricted Subsidiary
than those that would have been obtained in a comparable transaction by the Borrower or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis; and 
  

 105 

 (2) the Borrower delivers to the Administrative Agent with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $50,000,000, a resolution adopted by the majority of the Board of Directors of the Borrower approving such Affiliate Transaction and
set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 9.9(a). 
 (b) The provisions of Section 9.9(a) hereof shall not apply to the following:

the Sponsor Management Agreement (plus any unpaid management, consulting, monitoring and advisory fees and related expenses accrued in any prior year) and the termination fees pursuant to the Sponsor Management Agreement, in each case as in effect
on the Closing Date, or any amendment thereto (so long as any such amendment is not disadvantageous, in the good faith judgment of the Board of Directors of the Borrower, to the Lenders when taken as a whole as compared to the Sponsor Management
Agreement as in effect on the Closing Date); 
 (4) the payment of reasonable and customary fees paid to, and indemnities
provided for the benefit of, officers, directors, employees or consultants of Borrower, any of its direct or indirect parent companies or any of its Restricted Subsidiaries; 
 (5) transactions in which the Borrower or any of its Restricted Subsidiaries, as the case may be, delivers to the Administrative Agent a
letter from an Independent Financial Advisor stating that such transaction is fair to the Borrower or such Restricted Subsidiary from a financial point of view or stating that the terms are not materially less favorable to the Borrower or its
relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Borrower or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis; 
 (6) any agreement as in effect as of the Closing Date, or any amendment thereto (so long as any such amendment is not disadvantageous to
the Lenders when taken as a whole as compared to the applicable agreement as in effect on the Closing Date); 
 (7) the
existence of, or the performance by the Borrower or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement related thereto) to which it
is a party as of the Closing Date and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Borrower or any of its Restricted Subsidiaries of obligations under
any future amendment to any such existing agreement or under any similar agreement entered into after the Closing Date shall only be permitted by this clause (7) to the extent that the terms of any such amendment or new agreement are not
otherwise disadvantageous to the Lenders when taken as a whole; 
  

 106 

 (8) the Transactions (including payments made after the Closing Date in respect of the
Borrower’s and its Subsidiaries long-term incentive plan or in respect of gross-ups and other deferred compensation) and the payment of all fees and expenses related to the Transactions; 
 (9) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services in each case in the ordinary course of
business and otherwise in compliance with the terms of this Agreement which are fair to the Borrower and its Restricted Subsidiaries, in the reasonable determination of the Board of Directors of the Borrower or the senior management thereof, or are
on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party; 
 (10) the
issuance of Equity Interests (other than Disqualified Stock) of the Borrower to any Permitted Lender or to any director, officer, employee or consultant of the Borrower; 
 (11) sales of accounts receivable, or participations therein, in connection with any Receivables Facility for the benefit of the Borrower
or any of its Restricted Subsidiaries; 
 (12) payments by the Borrower or any of its Restricted Subsidiaries to any of the
Sponsors made for any financial advisory, financing, underwriting or placement services or in respect of other investment banking activities, including, without limitation, in connection with acquisitions or divestitures, which payments are approved
by a majority of the Board of Directors of the Borrower in good faith; 
 (13) payments or loans (or cancellation of loans) to
employees or consultants of the Borrower, any of its direct or indirect parent companies or any of its Restricted Subsidiaries and employment agreements, stock option plans and other similar arrangements with such employees or consultants which, in
each case, are approved by the Borrower in good faith; 
 (14) investments by the Sponsors in securities of the Borrower or
any of its Restricted Subsidiaries so long as (i) the investment is being offered generally to other investors on the same or more favorable terms and (ii) the investment constitutes less than 5% of the proposed or outstanding issue amount
of such class of securities; and 
 (15) payments by the Borrower (and any direct or indirect parent thereof) and its
Subsidiaries pursuant to tax sharing agreements among the Borrower (and any such parent) and its Subsidiaries on customary terms to the extent attributable to the ownership or operation of the Borrower and its Subsidiaries; provided that in
each case the amount of such payments in any fiscal year does not exceed the amount that the Borrower, its Restricted Subsidiaries and its Unrestricted Subsidiaries (to the extent of amounts received from Unrestricted Subsidiaries) would be required
to pay in respect of foreign, federal, state and local taxes for such fiscal year were the Borrower and its Subsidiaries (to the extent described above) to pay such taxes separately from any such parent entity. 
  

 107 

 9.10. Liens. The Borrower shall not, and shall not permit any Guarantor to, directly or
indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) that secures obligations under any Indebtedness or any related guarantee, on any asset or property of the Borrower or any Guarantor, or any income or profits
therefrom, or assign or convey any right to receive income therefrom, unless: 
 (1) in the case of Liens securing
Subordinated Indebtedness, the Loans and related Guarantees are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; or 
 (2) in all other cases, the Loans or the Guarantees are equally and ratably secured or are secured by a Lien on such property, assets or
proceeds that is senior in priority to such Liens; 
 except that the foregoing shall not apply to (a) Liens securing the Senior Notes and the related
Guarantees, (b) Liens securing Indebtedness permitted to be incurred under Credit Facilities, including any letter of credit relating thereto, that are permitted by the terms of this Agreement to be incurred pursuant to clause
(1) of Section 9.7(b) (provided, that prior to the Interim Loan Conversion Date, such Liens shall only secure Obligations in respect of Indebtedness not exceeding in the aggregate $25,200,000,000 outstanding at any one time) and
(c) after the Interim Loan Conversion Date, Liens incurred to secure Obligations in respect of any Indebtedness permitted to be incurred pursuant to the covenant described above under Section 9.7; provided that, with respect
to Liens securing Obligations permitted under this subclause (c), at the time of incurrence and after giving pro forma effect thereto, the Consolidated Secured Debt Ratio for the most recently ended four full fiscal quarters for which

 9.11. Corporate Existence. Subject to Sections 9.14 and 9.15, the Borrower shall do or cause to be done all things necessary to
preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be
amended from time to time) of the Borrower or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Borrower and its Restricted Subsidiaries; provided that the Borrower shall not be
required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Borrower in good faith shall determine that the preservation thereof is no longer desirable in
the conduct of the business of the Borrower and its Restricted Subsidiaries, taken as a whole. 
  

 108 

 9.12. Offer to Repurchase upon Change of Control. 
 (a) If a Change of Control occurs, unless otherwise prepaid in accordance with Section 5.2(a) or Section 9.8 hereof, the Borrower
shall make an offer to prepay all of the Loans pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Prepayment”) equal to 100% of the aggregate principal
amount thereof plus accrued and unpaid interest, to the date of prepayment, subject to the right of Lenders of record on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of
Control, the Borrower shall send notice of such Change of Control Offer by first-class mail, with a copy to the Administrative Agent, to each Lender to the address of such Lender appearing in the Register with a copy to the Administrative Agent,
with the following information: 
 (1) that a Change of Control Offer is being made pursuant to this Section 9.12
and that such Lender has the right to require the Borrower to prepay such Lender’s Loans; 
 (2) the prepayment amount
and the prepayment date, which will be no earlier than 30 days nor later than 60 days from the date such notice is mailed (the “Change of Control Prepayment Date”); 
 (3) that any Loans not properly accepted for prepayment pursuant to this Section 9.12 will remain outstanding and continue to
accrue interest; 
 (4) that unless the Borrower defaults in the prepayment of the Change of Control Prepayment, all Loans
accepted for prepayment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Prepayment Date; 
 (5) that Lenders shall be entitled to withdraw their election to require the Borrower to prepay such Loans, provided that the Borrower receives, not later than the close of business on the expiration date of
the Change of Control Offer, a facsimile transmission or letter setting forth the name of the Lender, the principal amount of Loans accepted for prepayment, and a statement that such Lender is withdrawing its election to have such Loans prepaid; and

 (6) the other instructions, as determined by the Borrower, consistent with this Section 9.12, that a Lender
must follow. 
 The notice, if mailed in a manner herein provided, shall be conclusively presumed to have been given, whether or not the
Lender receives such notice. If (a) the notice is mailed in a manner herein provided and (b) any Lender fails to receive such notice or a Lender receives such notice but it is defective, such Lender’s failure to receive such notice or
such defect shall not affect the validity of the proceedings for the purchase of the Loans as to all other Lenders that properly received such notice without defect. 
 (b) On the Change of Control Prepayment Date, the Borrower shall, to the extent permitted by law, 
 (i) prepay all Loans, or portions thereof, accepted for prepayment in accordance with this Section 9.12, pursuant to the Change of Control Offer; 
  

 109 

 (ii) deposit with the Administrative Agent an amount equal to the aggregate Change of
Control Prepayment in respect of all Loans or portions thereof so accreted for prepayment; and 
 (iii) deliver, or cause to
be delivered, to the Administrative Agent, an Officer’s Certificate to the Administrative Agent stating that such Loans or portions thereof have been prepaid by the Borrower. 
 (c) The Borrower shall not be required to make a Change of Control Offer following a Change of Control if a third-party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 9.12 applicable to a Change of Control Offer made by the Borrower and repays all Loans accepted for prepayment pursuant to such
Change of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of
Control at the time of making of the Change of Control Offer. 
 (d) Other than as specifically provided in this Section 9.12,
any prepayment pursuant to this Section 9.12 shall be made pursuant to the provisions of Sections 5.2, 5.5 and 5.6 hereof. 
 9.13. Limitation on Guarantees of Indebtedness by Restricted Subsidiaries. The Borrower shall not permit any of its Wholly-Owned Subsidiaries that are Restricted Subsidiaries (and non-Wholly-Owned Subsidiaries
if such non-Wholly-Owned Subsidiaries guarantee capital markets debt securities of the Borrower or any Guarantor), other than a Guarantor, a Foreign Subsidiary or a Receivables Subsidiary, to guarantee the payment of any Indebtedness of the Borrower
or any other Guarantor unless: 
 (1) such Restricted Subsidiary within 30 days executes and delivers a Guarantee
substantially in the form of Exhibit A hereto providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Borrower: 
 (a) if the Loans or such Guarantor’s Guarantee is subordinated in right of payment to such Indebtedness, the Guarantee shall be
subordinated to such Restricted Subsidiary’s guarantee with respect to such Indebtedness substantially to the same extent as the Loans are subordinated to such Indebtedness; and 
 (b) if such Indebtedness is by its express terms subordinated in right of payment to the Loans or such Guarantor’s Guarantee, any
such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee substantially to the same extent as such Indebtedness is subordinated to the Loans; and 
 (2) such Restricted Subsidiary waives, and shall not in any manner whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Borrower or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee; 
  

 110 

 provided that this Section 9.13 shall not be applicable to any guarantee of any Restricted Subsidiary
that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary. 
 9.14. Merger, Consolidation or Sale of All or Substantially All Assets. 
 (a) The Borrower shall not consolidate or merge with or into or wind up into (whether or not the Borrower is the surviving corporation), or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person unless: 
 (1) either: (x) the Borrower is the surviving corporation; or (y) the Person formed by or surviving any such consolidation or
merger (if other than the Borrower) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation organized or existing under the laws of the jurisdiction of organization of the Borrower or
the laws of the United States, any state thereof, the District of Columbia or any territory thereof (such Person, as the case may be, being herein called the “Successor Borrower”); 
 (2) the Successor Borrower, if other than the Borrower, expressly assumes all the obligations of the Borrower under the Loans pursuant to
a supplemental agreement or other documents or instruments in form reasonably satisfactory to the Administrative Agent; 
 (3)
immediately after such transaction, no Default exists; 
 (4) immediately after giving pro forma effect to such
transaction and any related financing transactions, as if such transactions had occurred at the beginning of the applicable four quarter period, 
 (A) the Successor Borrower would be permitted to incur at least $1.00 of additional Indebtedness pursuant to clause (i) of the Fixed Charge Coverage Ratio test set forth in Section 9.7(a)
hereof, or 
 (B) the Fixed Charge Coverage Ratio for the Successor Borrower and its Restricted Subsidiaries would be greater
than such ratio for the Borrower and its Restricted Subsidiaries immediately prior to such transaction; 
 (5) each Guarantor,
unless it is the other party to the transactions described above, in which case Section 9.14(c)(1)(B) hereof shall apply, shall have by supplemental agreement confirmed that its Guarantee shall apply to such Person’s obligations
under this Agreement and the Loans; and 
 (6) the Borrower shall have delivered to the Administrative Agent an Officer’s
Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental agreements, if any, comply with this Agreement and, if a supplemental agreement is required in connection with such transaction,
such supplement shall comply with the applicable provisions of this Agreement. 
  

 111 

 (b) The Successor Borrower shall succeed to, and be substituted for the Borrower, as the case may be,
under this Agreement, the Guarantees, the Loans, the Senior Refinancing Indenture and the Senior Notes, as applicable. Notwithstanding clauses (3) and (4) of Section 9.14(a) hereof, 
 (1) any Restricted Subsidiary may consolidate with or merge into or transfer all or part of its properties and assets to the Borrower, and

 (2) the Borrower may merge with an Affiliate of the Borrower, as the case may be, solely for the purpose of reincorporating
the Borrower in a State of the United States, the District of Columbia or any territory thereof so long as the amount of Indebtedness of the Borrower and its Restricted Subsidiaries is not increased thereby. 
 (c) Subject to certain limitations described in this Agreement governing release of a Guarantee upon the sale, disposition or transfer of a Guarantor, no
Guarantor shall, and the Borrower shall not permit any Guarantor to, consolidate or merge with or into or wind up into (whether or not the Borrower or Guarantor is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person unless: 
 (1)(A) such Guarantor is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition will
have been made is a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor, as the case may be, or the laws of the United

 (B) the Successor Person, if other than such Guarantor, expressly assumes all the obligations of such Guarantor under this Agreement and
such Guarantor’s related Guarantee pursuant to supplemental agreements or other documents or instruments in form reasonably satisfactory to the Administrative Agent; 
 (C) immediately after such transaction, no Default exists; and 
 (D) the Borrower shall have delivered to the Administrative Agent an Officer’s Certificate and an Opinion of Counsel, each stating

 (2)
the transaction is made in compliance with Section 9.8 hereof. 
  

 112 

 (d) Subject to certain limitations described in this Agreement, the Successor Person shall succeed to,
and be substituted for, such Guarantor under this Agreement and such Guarantor’s Guarantee. Notwithstanding the foregoing, any Guarantor may (i) merge into or transfer all or part of its properties and assets to another Guarantor or the
Borrower, (ii) merge with an Affiliate of the Borrower solely for the purpose of reincorporating such Guarantor in the United States, any state thereof, the District of Columbia or any territory thereof or (iii) convert into a corporation,
partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor. 
 (e) Notwithstanding anything to the contrary, the Transactions contemplated by the Agreement shall be permitted without compliance with this Section 9.14. 
 9.15. Successor Corporation Substituted. Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the assets of the Borrower in accordance with Section 9.14 hereof, the successor corporation formed by such consolidation or into or with which the Borrower is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this
Agreement referring to the Borrower shall refer instead to the successor corporation and not to the Borrower), and may exercise every right and power of the Borrower under this Agreement with the same effect as if such successor Person had been
named as the Borrower herein; provided that the predecessor Borrower shall not be relieved from the obligation to pay the principal of and interest, if any, on the Loans except in the case of a sale, assignment, transfer, conveyance or other
disposition of all of the Borrower’s assets that meets the requirements of Section 9.14 hereof.

to the Borrower or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists or is created after the issuance of the Loans, if both: 
 (i) such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or relates to an obligation other than the
obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity; and 
 (ii) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure

together would constitute a Significant Subsidiary), in a proceeding in which the Borrower or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), is to be adjudicated bankrupt
or insolvent; 
 (ii) appoints a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the
Borrower or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), or for all or substantially all of the property of the Borrower or any Significant Subsidiary (or any group of
Restricted Subsidiaries that together would constitute a Significant Subsidiary); or 
 (iii) orders the liquidation of the
Borrower or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary); 
 and the order or
decree remains unstayed and in effect for 60 consecutive days; or 
 (h) the Guarantee of any Significant Subsidiary (or group
of Restricted Subsidiaries that together would constitute a Significant Subsidiary) shall for any reason cease to be in full force and effect or be declared null and void or any responsible officer of any Guarantor that is a Significant Subsidiary
(or group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), as the case may be, denies that it has any further liability under its Guarantee or gives notice to such effect, other than by reason of the termination
of this Agreement or the release of any such Guarantee in accordance with this Agreement. 
 (II) In the event of any Event of
Default specified in clause (d) of Section 11.1(I) hereof, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Senior Interim Loans) shall
be annulled, waived and rescinded, automatically and without any action by the Administrative Agent or the Required Lenders, if within 20 days after such Event of Default arose: 
 (a) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged; or 
 (b) holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default;
or 
 (c) the default that is the basis for such Event of Default has been cured.

 11.16. Remedies upon Event of Default, Waivers of Past Defaults. 
 (a) If any Event of Default (other than an Event of
Default specified in clause (f) or (g) of Section 11.1(I) hereof) occurs and is continuing under this Agreement, (x) prior to the Interim Loan Conversion Date, the Administrative Agent may and, upon the
written request of the Required Lenders, shall and (y) on or after the Interim Loan Conversion Date, the Administrative Agent may, and upon written request of Lenders holding at least 30% in aggregate principal amount of the total Loans and
Senior Notes then outstanding shall declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Loans to be due and payable immediately. Upon the effectiveness of such declaration, such principal
and interest shall be due and payable immediately. 
 Notwithstanding the foregoing, in the case of an Event of Default arising under
clause (f) or (g) of Section 11.1(I) hereof, all outstanding Loans shall be due and payable immediately without further action or notice. 
 (b) The Required Lenders by notice to the Administrative Agent may on behalf of all Lenders waive any existing Default and its consequences hereunder,
except a continuing Default in the payment of the principal of, premium, if any, or interest on, any Loans (held by a Non-Consenting Lender) and rescind any acceleration with respect to the Loans and its consequences (provided such rescission would
not conflict with any judgment of a court of competent jurisdiction; and that the Required Lenders may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver,
such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Agreement; but no such waiver shall extend to any subsequent or other Default or impair any right consequent
thereon. 
  

 116 

 11.17. Application of Proceeds. Any amount received by the Administrative Agent from any Loan
Party following any acceleration of the Obligations under this Agreement or any Event of Default with respect to the Borrower under Section 11.1(I)(f) or (g) shall be applied: 
 (i) first, to the payment of all reasonable and documented costs and expenses incurred by the Administrative Agent in connection
with any collection or sale or otherwise in connection with any Loan Document, including all court costs and the reasonable fees and expenses of its agents and legal counsel, the repayment of all advances made by the Administrative Agent hereunder
or under any other Loan Document on behalf of any Loan Party and any other reasonable and documented costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Loan Document; 
 (ii) second, to the Guaranteed Parties, an amount (x) equal to all Obligations owing to them on the date of any distribution
and such moneys shall be insufficient to pay such amounts in full, then ratably (without priority of any one over any other) to such Guaranteed Parties in proportion to the unpaid amounts thereof; and 
 (iii) third, any surplus then remaining shall be paid to the applicable Loan Parties or their successors or assigns or to
whomsoever may be lawfully entitled to receive the same or as a court of competent jurisdiction may direct. 
 SECTION 12. The Agents.

 12.1. Appointment. 
 (a) Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under this Agreement and the other Loan Documents and irrevocably authorizes the Administrative Agent, in such capacity, to take
such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other
Loan Documents, together with such other powers as are reasonably incidental thereto. The provisions of this Section 12 (other than Sections 12.9 and 12.11 with respect to the Borrower) are solely for the benefit of
the Agents and the Lenders, and the Borrower shall not have any rights as a third party beneficiary of such provision. Notwithstanding any provision to the contrary elsewhere in this Agreement, no Agent shall have any duties or responsibilities,
except those expressly set forth herein, or in any other Loan Document, any fiduciary relationship with any Lender or any agency or trust obligations with respect to any Loan Party, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against such Agent. 
 (b)
[Reserved]. 
  

 117 

 (c) Each of the Syndication Agent, the Joint Lead Arrangers and Bookrunners and the Co-Documentation
Agents, each in its capacity as such, shall not have any obligations, duties or responsibilities under this Agreement but shall be entitled to all benefits of this Section 12. 
 12.2. Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through
agents, sub-agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents,
sub-agents or attorneys-in-fact selected by it in the absence of gross negligence or willful misconduct (as determined in the final judgment of a court of competent jurisdiction). 
 12.3. Exculpatory Provisions. 
 (a)
No Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by any of them under or in connection with this Agreement or any other Loan
Document (except for its or such Person’s own gross negligence or willful misconduct, as determined in the final judgment of a court of competent jurisdiction, in connection with its duties expressly set forth herein) or (ii) responsible
in any manner to any of the Lenders or any participant for any recitals, statements, representations or warranties made by the Borrower, any Guarantor or any officer thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in, or received by such Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document or for any failure of the Borrower or any Guarantor to perform its obligations hereunder or thereunder. No Agent shall be under any obligation to any Lender to ascertain or to inquire as to
the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party or Affiliate thereof. 
 (b) Each Lender confirms to the Administrative Agent, each other Lender and each of their respective Related Parties that it (i) possesses
(individually or through its Related Parties) such knowledge and experience in financial and business matters that it is capable, without reliance on the Administrative Agent, any other Lender or any of their respective Related Parties, of
evaluating the merits and risks (including tax, legal, regulatory, credit, accounting and other financial matters) of (x) entering into this Agreement, (y) making Loans and other extensions of credit hereunder and under the other Loan
Documents and (z) in taking or not taking actions hereunder and thereunder, (ii) is financially able to bear such risks and (iii) has determined that entering into this Agreement and making Loans and other extensions of credit
hereunder and under the other Loan Documents is suitable and appropriate for it. 
 (c) Each Lender acknowledges that (i) it is solely
responsible for making its own independent appraisal and investigation of all risks arising under or in connection with this Agreement and the other Loan Documents, (ii) that it has, independently and without reliance upon the Administrative
Agent, any other Lender or any of their respective Related Parties, made its own appraisal and investigation of all risks associated with, and its own credit analysis and decision to enter into, this Agreement based on such documents and
information, as it has 

  

 118 

 
deemed appropriate and (iii) it will, independently and without reliance upon the Administrative Agent, any other Lender or any of their respective
Related Parties, continue to be solely responsible for making its own appraisal and investigation of all risks arising under or in connection with, and its own credit analysis and decision to take or not take action under, this Agreement and the
other Loan 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 Loan Party; 
 (ii) the legality, validity, effectiveness, adequacy or enforceability of this Agreement and each other Loan Document and any other agreement, arrangement or document entered into, made or executed in anticipation of, under or in connection
with any Loan Document; 
 (iii) determining compliance or non-compliance with any condition hereunder to the making of a Loan
and the form and substance of all evidence delivered in connection with establishing the satisfaction of each such condition; 
 (iv) the adequacy, accuracy and/or completeness of any information delivered by the Administrative Agent, any other Lender or by any of their respective Related Parties under or in connection with this Agreement or any other Loan 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 Loan Document. 
 12.4. Reliance by Agents. The Administrative 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 the Borrower), independent accountants and other experts selected by the Administrative Agent. The Administrative 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. The Administrative
Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders 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 shall in all cases be fully protected in acting,
or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders, 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; provided that the Administrative 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 Loan Document or
Applicable Laws. For purposes of determining compliance with the conditions specified in Section 6 on the Closing Date, each 
  

 119 

 
Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter
required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objection thereto.

 12.5. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default
or Event of Default hereunder unless the Administrative Agent has received notice from a Lender 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 receives such a notice, it shall give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders, provided that unless and until the Administrative Agent shall have received such directions, the Administrative 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 each of the Lenders, as applicable. 
 12.6. Non-Reliance on
Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its 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 hereinafter taken, including any review of the affairs of the Borrower, any Guarantor or any other Loan Party, shall be deemed to constitute any representation or warranty by the Administrative Agent to
any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Guaranteed Party, 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 the Borrower and each Guarantor and made its own decision to make its Loans hereunder and enter into this
Agreement. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent or any 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 Loan 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 the Borrower, any Guarantor and any other Loan Party. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative
Agent shall not 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 the Borrower, any Guarantor or
any other Loan Party that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates. 
  

 120 

 12.7. Indemnification. The Lenders agree to indemnify each Agent, each in its capacity as such (to
the extent not reimbursed by the Loan Parties and without limiting the obligation of the Loan 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 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) or be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of the Commitments, this Agreement, any of the other Loan 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 such 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 Loan 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 or be imposed upon, incurred by or asserted against any Agent in any way relating to or arising out of the Commitments, this Agreement, any of the other Loan 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), 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 Loan 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 a court of competent jurisdiction). The agreements in this Section 12.7 shall survive the payment of the Loans and all other amounts payable
hereunder. 
  

 121 

 12.8. Agents in their Individual Capacity. Each Agent and its Affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrower, any Guarantor, and any other Loan Party as though such Agent were not an Agent hereunder and under the other Loan Documents. With respect to the Loans made by it, each
Agent shall have the same rights and powers under this Agreement and the other Loan 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. The Administrative Agent may resign at any time by notifying
the Lenders 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, appoint a successor Agent meeting the qualifications set forth above; provided that if the Administrative 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 Administrative Agent shall be discharged from its
duties and obligations hereunder and under the other Loan Documents 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 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 a successor Administrative Agent as provided for above in this
paragraph. Upon the acceptance of a successor’s appointment as the Administrative Agent hereunder, and upon the transfer by the retiring (or retired) Agent to the successor Agent of all sums, together with all records and other documents
necessary or appropriate in connection with the performance of the duties of the successor Agent under the Loan 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 Loan Documents (if not already discharged therefrom as provided above in this Section 12.9). 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 Loan 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. 
  

 122 

 12.10. Withholding Tax. To the extent required by any Applicable Laws, the Administrative 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
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 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 (solely to the extent required by this Agreement) (to the extent that the
Administrative Agent has not already been reimbursed by the Borrower and without limiting the obligation of the Borrower to do so) fully for all amounts paid, directly or indirectly, by the Administrative 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 Morgan Stanley Senior Funding, Inc. 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 Loan Party, and agree that any payment or property received in satisfaction of or in respect of any Obligation of such Loan Party hereunder or under any other Loan Document by
or on behalf of Morgan Stanley Senior Funding, Inc., in its capacity as the Administrative Agent for the benefit of any Lender under any Loan Document (other than Morgan Stanley Senior Funding, Inc. or an Affiliate of Morgan Stanley Senior Funding,
Inc.) and which is applied in accordance with the Loan Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act. 
 12.12. Guarantee. 
 (a) Agent
under Guarantee. Each Guaranteed Party hereby further authorizes the Administrative Agent, on behalf of and for the benefit of the Guaranteed Parties, to be the agent for and representative of the Guaranteed Parties with respect to the
Guarantee. Subject to Section 13.1, without further written consent or authorization from any Guaranteed Party, the Administrative Agent may execute any documents or instruments necessary to, in connection with a sale or disposition of
assets permitted by this Agreement, release any Guarantor from the Guarantee or elect any such release 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 Enforce Guarantee. Anything contained in any of the Loan Documents to the contrary
notwithstanding, the Borrower, the Agents and each Guaranteed Party hereby agree that no Guaranteed Party shall have any right individually 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 Guaranteed Parties in accordance with the terms hereof and all powers, rights and remedies under the Guarantee may be exercised solely by the Administrative Agent on behalf of the
Guaranteed Parties. 
  

 123 

 SECTION 13. Miscellaneous. 
 13.1. Amendments, Waivers and Releases. 
 (a) Neither this Agreement nor any other Loan 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 may, from time to time, (a) enter into with the relevant Loan Party or Loan Parties written amendments, supplements or modifications hereto and to the other Loan Documents
for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Loan Parties hereunder or thereunder or (b) waive in writing, on such terms and conditions as
the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences or (c) consent
to amendments, supplements or modifications to the form of the Senior Refinancing Indenture prior to the Interim Loan Conversion Date; provided, however, that 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 extend the final scheduled maturity date of any Loan or reduce the stated rate (it being understood that 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), or extend the final expiration date of any Lender’s Commitment, 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, interest, fee or other amount payable in any currency other than Dollars, in each case without the written consent of each Lender directly
affected thereby, or (ii) amend, modify or waive any provision of this Section 13.1 or reduce the percentages specified in the definitions of the term “Required Lenders,” consent to the assignment or transfer by the
Borrower of its rights and obligations under any Loan Document to which it is a party (except as permitted pursuant to Section 9.14) or alter the order of application set forth in the final paragraph of Section 11 or in
Section 5.2(c), in each case without the written consent of each Lender directly affected thereby, or (iii) amend, modify, terminate or waive any provision of Section 12 without the written consent of the then-current
Administrative Agent or any other former or current Agent to whom Section 12 then applies in a manner that directly affects such Person, or (iv) release all or substantially all of the Guarantors under the Guarantee (except as
expressly permitted by the Guarantee or this Agreement) without the prior written consent of each Lender, or (v) amend, modify or waive any provision of Section 2.14, or (vi) amend or modify any provision of the Senior
Refinancing Indenture that requires (or would, if any Senior Notes were outstanding require) the approval of all holders of Senior Notes, without the written consent of each Lender directly and adversely affected thereby, or (vii) affect the
rights or duties of, or any fees or other amounts payable to, any Agent under this Agreement or any other Loan Document without the prior written consent of such Agent. Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the affected Lenders and shall be binding upon the Borrower, the applicable Loan Parties, such Lenders, the Administrative Agent and all future holders of the affected Loans. In the case of any waiver, the Borrower, the applicable
Loan Parties, the Lenders and the Administrative Agent shall be restored to their former positions and 

  

 124 

 
rights hereunder and under the other Loan 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 may, but shall have no obligations to,
with the concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of such Lender. 
 (b) Notwithstanding
the foregoing, without notice to or the consent of any Lenders and without any further action necessary by the parties hereto, effective as of the date set forth in clause (a) of the definition of “Maturity Date,” in the
event of any inconsistency between the terms contained in Sections 8, 9 and 11 of this Agreement and the corresponding terms contained in the Senior Refinancing Indenture, such provisions of this Agreement shall be replaced with
corresponding provisions of the Senior Refinancing Indenture, and, to the extent necessary to give effect to the foregoing, each defined term used in the sections of the Senior Refinancing Indenture shall have the meaning set forth in the Senior
Refinancing Indenture, subject to the terms of Section 1.2(h), as applicable. The applicable provisions of the Senior Refinancing Indenture as described in Exhibit C shall be deemed incorporated and set forth in this Agreement to the
extent necessary to give effect to the foregoing. In furtherance of the foregoing, the Administrative Agent will (and the Lenders hereby authorize and direct the Administrative Agent to), at the request of the Borrower, enter into such technical
amendments and other modifications to this Agreement as are reasonably necessary to effect the foregoing. 
 (c) 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 or Loans 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. 
 (d) The Lenders hereby irrevocably agree that a Guarantor shall be released from its Guarantee and no further action by
such Guarantor, the Borrower or the Administrative Agent is required for the release of such Guarantor’s Guarantee, upon: (1)(A) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of such Guarantor (including any
sale, exchange or transfer after which the applicable Guarantor is no longer a Restricted Subsidiary) or a sale of all or substantially all the assets of such Guarantor which sale, exchange or transfer is made in compliance with the applicable
provisions of this Agreement; (B) the release or discharge of the guarantee by such Guarantor of the Senior Secured Credit Agreement or such other guarantee that resulted in the creation of such Guarantee, except a discharge or release by or as
a result of payment under such Guarantee; (C) the designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in compliance with Section 9.5 hereof and the definition of “Unrestricted

 125 

 (e) The Lenders hereby authorize the Administrative Agent to execute and deliver any instruments,
documents, and agreements necessary or desirable to evidence and confirm the release of any Guarantor pursuant to the foregoing provisions of clause (c), all without the further consent or joinder of any Lender 
 13.2. Notices. Unless otherwise expressly provided herein, all notices and other communications provided for hereunder or under any other Loan

 13.3. No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right, remedy, power or privilege hereunder or under the other
Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. 
 13.4. Survival of Representations and Warranties. All representations and warranties made hereunder, in the other Loan Documents and in any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement and the making of the Loans hereunder. 
 13.5. Payment of

and any amendment, supplement or modification to, this Agreement and the other Loan Documents and 

  

 126

delayed) retains its own counsel, of another firm of counsel for such affected Person) (c) to pay, indemnify, and hold harmless each Lender and Agent from, any and all recording and filing fees and (d) to pay, indemnify, and hold harmless
each Lender and Agent and their respective Affiliates, directors, officers, partners, employees and agents from and against any and all other liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs,

in each appropriate jurisdiction, in each case, to all indemnified Persons (and in the case of an actual or perceived conflict of interest where the Person affected by such conflict informs the Borrower of such conflict and thereafter, after receipt
of the consent of the Borrower (which consent shall not be unreasonably withheld or delayed), retains its own counsel, of another firm of counsel for such affected Person), related to the Transactions or, with respect to the execution, delivery,
enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including any of the foregoing relating to the violation of, noncompliance with or liability under, any Environmental Law (other
than by such indemnified person or any of its Related Parties (other than any trustees or advisors)) or to any actual or alleged presence, release or threatened release into the environment of Hazardous Materials attributable to the operations of
the Borrower, any of its Subsidiaries or any of the Real Estate (all the foregoing in this clause (d), collectively, the “indemnified liabilities”) (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 the Borrower shall have no obligation hereunder to any Agent or any Lender or any of their respective Related
Parties with respect to indemnified liabilities to the extent it has been determined by a final non-appealable judgment of a court of competent jurisdiction to have resulted from (A) the gross negligence, bad faith or willful misconduct of such
Indemnified Party or any of its Related Parties (other than trustees and advisors), (B) a breach of the obligations of such Indemnified Party or any of its Related Parties (other than trustees and advisors) under the Loan Documents or
(C) disputes not involving an act or omission of the Borrower or any other Loan Party or any of their respective Affiliates and that is brought by an Indemnified Party against any other Indemnified Party. All amounts payable under this

consequential damages resulting from this Agreement or any other Loan Document or arising out of its activities in connection herewith or therewith (whether before or after the Closing Date) (except, in the case of the Borrower’s obligation
hereunder to indemnify and hold harmless the Indemnified Parties, to the extent any Indemnified Party is found liable for special, punitive, indirect or consequential damages to a third party). No Indemnified Party shall be liable for any damages
arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or
the transactions contemplated hereby or thereby, except to the extent that such damages have resulted from the willful misconduct, bad faith or gross negligence of any Indemnified Party or any of its Related Parties (as determined by a final
non-appealable judgment of a court of competent jurisdiction). 
 13.6. Successors and Assigns; Participations and Assignments.

 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors
and assigns permitted hereby, except that (i) except as expressly permitted by Section 9.14, the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the
Administrative Agent and each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in
accordance with this Section 13.6. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to
the extent provided in clause (c) of this Section 13.6) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders and each other Person entitled to
indemnification under Section 13.5) and, to the extent expressly contemplated by Section 13.21, the Oncor Subsidiaries) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
 (b) Subject to the conditions set forth in clause (b)(ii) below, any Lender may at any time assign to one or more assignees all or a portion
of its rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it) with the prior written consent (such consent not be unreasonably withheld or delayed) of the Administrative
Agent (which consent shall not be unreasonably withheld or delayed) provided that no consent of the Administrative Agent shall be required for any assignment of any Loan to a Lender, an Affiliate of a Lender or an Approved Fund. 

 

 128 

 Notwithstanding the foregoing, no such assignment shall be made to a natural person. 
 (i) Assignments shall be subject to the following additional conditions: 
 (A) except (1) in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or an assignment of the entire
remaining amount of the assigning Lender’s Commitment or Loans of any Class, (2) an assignment to a Federal Reserve Bank or (3) in connection with the initial syndication of the Commitments and Loans, the amount of the Commitment or
Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 and increments of
$1,000,000 in excess thereof, unless each of the Borrower and the Administrative Agent otherwise consents (which consents shall not be unreasonably withheld or delayed), provided that no such consent of the Borrower shall be required if an
Event of Default under clause (a), (b), (f) or (g) of Section 11.1(I) has occurred and is continuing with respect to the Borrower; provided, further, that contemporaneous assignments to a
single assignee made by Affiliates of Lenders and related Approved Funds shall be aggregated for purposes of meeting the minimum assignment amount requirements stated above; 
 (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and
obligations under this Agreement; provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Commitments or Loans;

 (C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance;

 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire in
a form approved by the Administrative Agent (the “Administrative Questionnaire”); and 
 (E) prior to the
Interim Loan Conversion Date, no Committed Lender shall assign to another Lender (other than an Affiliate of such Lender or an Approved Fund) any Loans without the Borrower’s prior consent (it being understood that, without limitation, the
Borrower shall have the right to withhold or delay its consent to any assignment if, in order for such assignment to comply with Applicable Laws, the Borrower would be required to obtain the consent of, or make any filing or registration with, any
Government Authority) if, after giving effect to such assignment, the Committed Lenders (together with their respective Affiliates) would hold, in the aggregate, less than 51% of the aggregate principal amount of outstanding Loans (it being
understood that, as provided in clause (b)(i)(A)(3) of this Section 13.6, the Borrower’s consent shall not otherwise be required in connection with the initial syndication of the Commitments and the Loans). 
 (ii) Subject to acceptance and recording thereof pursuant to clause (b)(iv) of this Section 13.6, from and
after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent 

  

 129 

 
of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.10, 2.11, 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. 
 (iii) 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 register for the recordation of the
names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). Further, the Register shall contain the name and
address of the Administrative Agent and the lending office through which each such Person acts under this Agreement. The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders shall treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender at
any reasonable time and from time to time upon reasonable prior notice. 
 (iv) Upon its receipt of a duly completed
Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in
clause (b) of this Section 13.6 and any written consent to such assignment required by clause (b) of this Section 13.6, the Administrative Agent shall accept such Assignment and Acceptance and record
the information contained therein in the Register. 
 (c) (a) Any Lender may, without the consent of the Borrower or the Administrative
Agent, 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 and the
Loans owing to it), provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations,
and (iii) the Borrower, the Administrative Agent 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 Loan
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 clause (i), or
(iv) of the proviso to 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 

  

 130 

 
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 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. 
 (i) 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). 
 (ii) 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 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 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 and the Borrower at any reasonable time and from time to time upon reasonable prior notice. 
 (d) Any Lender may, without the consent of the Borrower or the Administrative 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 the 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 I-1 or I-2, as the case may be evidencing the Loans owing to such Lender. 
 (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 transaction to be entered into in connection with or relating to Loans 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 such Affiliates prior to becoming a party to this Agreement. 
  

 131 

 (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. 
 13.7.
Replacements of Lenders under Certain Circumstances. 
 (a) The Borrower shall be permitted to replace any Lender that
(i) requests reimbursement for amounts owing pursuant to Section 2.10 or 5.4, (ii) is affected in the manner described in Section 2.10(a)(iii) and as a result thereof any of the actions described in such
Section is required to be taken or (iii) becomes a Defaulting Lender, with a replacement bank or other financial institution; provided that (A) such replacement does not conflict with any Applicable Laws, (B) no Event of
Default under clause (a), (b), (f) or (g) of Section 11.1(I) shall 

  

 132 

 
have occurred and be continuing at the time of such replacement, (C) the Borrower shall repay (or the replacement bank or institution shall purchase, at
par,) all Loans and other amounts (other than any disputed amounts), pursuant to Section 2.10, 2.11 or 5.4, as the case may be, owing to such replaced Lender prior to the date of replacement, (D) the replacement bank
or institution, if not already a Lender, and the terms and conditions of such replacement, shall be reasonably satisfactory to the Administrative Agent, (E) the replaced Lender shall be obligated to make such replacement in accordance with the
provisions of Section 13.6 and (F) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender. 
 (b) If any Lender (such Lender, a “Non-Consenting Lender”) has failed to consent to a proposed amendment, modification, supplement,
waiver, discharge or termination that pursuant to the terms of Section 13.1 requires the consent of all of the Lenders or all Lenders affected and with respect to which the Required Lenders shall have granted their consent, then provided
no Event of Default then exists, the Borrower shall have the right (unless such Non-Consenting Lender grants such consent) to replace such Non-Consenting Lender by requiring such Non-Consenting Lender to assign its Loans and its Commitments
hereunder to one or more assignees reasonably acceptable to the Administrative Agent: provided that (i) all Obligations of the Borrower owing to such Non-Consenting Lender being replaced shall be paid in full to such Non-Consenting
Lender concurrently with such assignment and (ii) the replacement Lender shall purchase the foregoing by paying to such Non-Consenting Lender a price equal to the principal amount thereof plus accrued and unpaid interest thereon. In
connection with any such assignment, the Borrower, Administrative Agent, such Non-Consenting Lender and the replacement Lender shall otherwise comply with Section 13.6. 
 13.8. Adjustments; Set-off. 
 (a) If
any Lender (a “benefited Lender”) shall at any time receive any payment of all or part of its Loans, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to
events or proceedings of the nature referred to in clause (f) or (g) of Section 11.1(I), 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 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 shall provide such other Lenders with the
benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefited Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, however,
that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

 (b) After the occurrence and during the continuance of an Event of Default, in addition to any rights and remedies of the Lenders provided
by Applicable Laws, each Lender shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by Applicable Laws, upon any amount becoming due and payable by the Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general 

  

 133 

 
or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and
the Administrative Agent after any such set-off and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such set-off and application. 
 13.9. Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts
(including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with
the Borrower and the Administrative Agent. 
 13.10. Severability. Any provision of this Agreement that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
 13.11. Integration. THIS WRITTEN AGREEMENT AND THE
OTHER LOAN DOCUMENTS REPRESENT THE AGREEMENT OF THE BORROWER, THE ADMINISTRATIVE AGENT AND (1) THERE ARE NO PROMISES, UNDERTAKINGS, REPRESENTATIONS OR WARRANTIES BY US HOLDINGS, TCEH, TCEH FINANCE, THE ADMINISTRATIVE AGENT OR ANY LENDER
RELATIVE TO SUBJECT MATTER HEREOF NOT EXPRESSLY SET FORTH OR REFERRED TO HEREIN, IN THE OTHER LOAN DOCUMENTS, IN THE FEE LETTER OR THE ENGAGEMENT LETTER, (2) THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES AND (3) THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES; PROVIDED, THAT THE FEE LETTER, THE ENGAGEMENT LETTER AND THE SYNDICATION PROVISIONS AND THE
BORROWER’S CONFIDENTIALITY OBLIGATIONS IN THE COMMITMENT LETTER SHALL REMAIN IN FULL FORCE AND EFFECT. IT IS SPECIFICALLY AGREED THAT PROVISION OF THE CREDIT FACILITIES HEREUNDER BY THE LENDERS SUPERSEDES AND IS IN SATISFACTION OF THE
OBLIGATIONS OF THE AGENTS (AS DEFINED IN THE COMMITMENT LETTER) TO PROVIDE THE COMMITMENTS SET FORTH IN EXHIBIT C OF THE COMMITMENT LETTER. 
 13.12. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
  

 134 

 13.13. Submission to Jurisdiction; Waivers. Each party hereto irrevocably and unconditionally:

 (a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which
it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York
and appellate courts from any thereof; 
 (b) consents that any such action or proceeding may be brought in such courts and waives any

 (c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid, to such Person at its address set forth on Schedule 13.2 or at such other address of which the Administrative Agent shall have been notified pursuant to Section 13.2;

 (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the
right to sue in any other jurisdiction; 
 (e) subject to the last paragraph of Section 13.5, waives, to the maximum extent not
prohibited by Applicable Laws, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 13.13 any special, exemplary, punitive or consequential damages; and 
 (f) agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in
any other manner provided by Applicable Laws. 
 13.14. Acknowledgments. The Borrower hereby acknowledges that: 
 (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents; 
 (b) (i) the Loans provided for hereunder and any related arranging or other services in connection therewith (including in connection with any
amendment, waiver or other modification hereof or of any other Loan Document) are an arm’s-length commercial transaction between the Borrower and the other Loan Parties, on the one hand, and the Administrative Agent, the Lenders and the other
Agents on the other hand, and the Borrower and the other Loan Parties are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents
(including any amendment, waiver or other modification hereof or thereof); (ii) in connection with the process leading to such transaction, each of the Administrative Agent and the other Agents is and has been acting solely as a principal and

Document (irrespective of whether the Administrative Agent or any other Agent has advised or is currently advising the Borrower, the other Loan Parties or their respective Affiliates on other matters) and neither the Administrative Agent or any
other Agent has any obligation to the Borrower, the other Loan Parties or their respective Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents;
(iv) the Administrative Agent, each other Agent and each Affiliate of the foregoing may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and neither the Administrative
Agent nor any other Agent has any obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) neither the Administrative Agent nor any other Agent has provided and none will provide any

accounting, regulatory and tax advisors to the extent it has deemed appropriate. The Borrower agrees not to claim that the Administrative Agent or any other Agent has rendered advisory services of any nature or respect, or owes a fiduciary or
similar duty to the Borrower or any other Affiliates, in connection with the transactions contemplated hereby or the process leading hereto; and 
 (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Borrower, on the one hand, and any Lender, on the other hand.

whether to become a Lender hereunder or obtained by such Lender, the Administrative Agent or such other Agent pursuant to the requirements of this Agreement (“Confidential Information”), confidential in accordance with its customary
procedure for handling confidential information of this nature and (in the case of a Lender that is a bank) in accordance with safe and sound banking practices and in any event may make disclosure as required or requested by any governmental,
regulatory or self-regulatory agency or representative thereof or pursuant to legal process or Applicable Laws or (a) to such Lender’s or the Administrative Agent’s or such other Agent’s attorneys, professional advisors,
independent auditors, trustees or Affiliates, (b) to an investor or prospective investor in a Securitization that agrees its access to information regarding the Loan Parties, the Loans and the Loan Documents is solely for purposes of evaluating
an investment in a Securitization and who agrees to treat such information as confidential, (c) to a trustee, collateral manager, servicer, backup servicer, noteholder or secured party in connection with the administration, servicing and

 136 

 
agency that requires access to information regarding the Loan Parties, the Loans and Loan Documents in connection with ratings issued with respect to a
Securitization; provided that unless specifically prohibited by Applicable Laws or court order, each Lender and the Administrative Agent and each other Agent shall use commercially reasonable efforts to notify the Borrower of any request made
to such Lender, the Administrative Agent or such other Agent, as applicable, by any governmental, regulatory or self-regulatory agency or representative thereof (other than any such request in connection with a routine examination of such Lender by
such governmental, regulatory or self-regulatory agency) for disclosure of any such non-public information prior to disclosure of such information; and provided further that in no event shall any Lender, the Administrative Agent or any
other Agent be obligated or required to return any materials furnished by the Borrower or any Subsidiary of the Borrower. Each Lender, the Administrative Agent and each other Agent agrees that it will not provide to prospective Transferees or to any
pledgee referred to in Section 13.6 or to prospective direct or indirect contractual counterparties to any swap or derivative transactions to be entered into in connection with or relating to Loans made hereunder any of the Confidential
Information unless such Person is advised of and agrees to be bound by the provisions of this Section 13.16 or confidentiality provisions at least as restrictive as those set forth in this Section 13.16. 
 13.17. Direct Website Communications. 
 (a) The Borrower may, at its option, provide to the Administrative Agent any information, documents and other materials that it is obligated to furnish to the Administrative Agent pursuant to the Loan Documents, including all notices,
requests, financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (A) relates to a request for a new, or a conversion of an existing, Borrowing or other
extension of credit (including any election of an interest rate or Interest Period relating thereto), (B) relates to the payment of any principal or other amount due under this Agreement prior to the scheduled date therefor, (C) provides
notice of any Default or Event of Default under this Agreement or (D) is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any Borrowing (all such non-excluded communications being
referred to herein collectively as “Communications”), by transmitting the Communications in an electronic/soft medium in a format reasonably acceptable to the Administrative Agent to the Administrative Agent at the e-mail address as
set forth on Schedule 13.2; provided that: (i) upon written request by the Administrative Agent, the Borrower shall deliver paper copies of such documents to the Administrative Agent for further distribution to each Lender
until a written request to cease delivering paper copies is given by the Administrative Agent and (ii) the Borrower shall notify (which may be by facsimile or electronic mail) the Administrative Agent of the posting of any such documents and
provide to the Administrative Agent by electronic mail electronic versions (i.e., soft copies) of such documents. Each Lender shall be solely responsible for timely accessing posted documents or requesting delivery of paper copies of such documents
from the Administrative Agent and maintaining its copies of such documents. Nothing in this Section 13.17 shall prejudice the right of the Borrower, the Administrative Agent, any other Agent or any Lender to give any notice or other
communication pursuant to any Loan Document in any other manner specified in such Loan Document. 
  

 137 

 (b) The Administrative Agent agrees that the receipt of the Communications by the Administrative Agent at
its e-mail address set forth on Schedule 13.2 shall constitute effective delivery of the Communications to the Administrative Agent for purposes of the Loan Documents. Each Lender agrees that notice to it (as provided in the next
sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (A) to notify the Administrative Agent
in writing (including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notice may be sent by electronic transmission and (B) that the foregoing notice may be sent to such e-mail address.

 (c) The Borrower further agrees that the Agents may make the Communications available to the Lenders by posting the Communications on
Intralinks or a substantially similar electronic transmission system (the “Platform”), so long as the access to such Platform is limited (i) to the Agents, the Lenders or any bonafide potential Transferee and (ii) remains
subject to the confidentiality requirements set forth in Section 13.16. 
 (d) THE PLATFORM IS PROVIDED “AS IS”
AND “AS AVAILABLE”. THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE
COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY
AGENT PARTY IN CONNECTION WITH THE COMMUNICATIONS. In no event shall any Agent or any of its Related Parties (collectively, the “Agent Parties” and each an “Agent Party”) have any liability to the Borrower, any
Lender or any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or otherwise) arising out of the Borrower’s or any Agent’s transmission of communications by electronic Communication
(including e-mail and internet or intranet websites, including the Platform), except to the extent the liability of any Agent Party’s (or any of its Related Parties’ (other than trustees or advisors)) resulted from such Agent Party’s
gross negligence, bad faith or willful misconduct or material breach of the Loan Documents as determined in a final non-appealable judgment of a court of competent jurisdiction). 
 (e) The Borrower and each Lender acknowledge that certain of the Lenders may be “public-side” Lenders (Lenders that do not wish to receive
material non-public information with respect to the Borrower, the Subsidiaries of the Borrower or their securities) and, if documents or notices required to be delivered pursuant to the Loan Documents or otherwise are being distributed through the
Platform, any document or notice that the Borrower has indicated contains only publicly available information with respect to the Borrower and the Subsidiaries of the Borrower and their securities may be posted on that portion of the Platform
designated for such public-side Lenders. If the Borrower has not indicated whether a document or notice delivered contains only publicly available information, the Administrative Agent shall post such document or notice solely on that portion of the
Platform designated for Lenders who wish to receive material nonpublic information with respect to the Borrower, the Subsidiaries of the Borrower and their securities. Notwithstanding the foregoing, the Borrower shall use commercially reasonable
efforts to indicate whether any document or notice contains only publicly available information. 
  

 138 

 13.18. USA PATRIOT Act. Each Lender hereby notifies the Borrower that pursuant to the requirements
of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies each Loan Party, which information includes
the name and address of each Loan Party and other information that will allow such Lender to identify each Loan Party in accordance with the Patriot Act. 
 13.19. Payments Set Aside. To the extent that any payment by or on behalf of the Borrower is made to any Agent or any Lender, or any Agent or any Lender exercises its right of setoff, and such payment or the
proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Agent or such Lender in its discretion) to be repaid
to a trustee, receiver or any other party, in connection with any proceeding or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender severally agrees to pay to the Administrative Agent upon demand its applicable share of any amount so recovered from or repaid by any Agent,
plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the applicable Overnight Rate from time to time in effect. 
 13.20. Separateness. The Guaranteed Parties acknowledge (i) the legal separateness of the Borrower and the Guarantors from the Oncor
Subsidiaries, (ii) that the lenders under the Oncor Electric Delivery Facility and the noteholders under the Existing Oncor Notes and under the transition bonds have likely advanced funds thereunder in reliance upon the separateness of the
Oncor Subsidiaries from the Borrower and the Guarantors, (iii) that the Oncor Subsidiaries have assets and liabilities that are separate from those of the Borrower and the Guarantors, (iv) that the obligations under the Loan Documents are
obligations and liabilities of the Borrower and the Guarantors only, and are not the obligations or liabilities of Oncor Holdings or any of the Oncor Subsidiaries, (v) that the Guaranteed Parties shall look solely to the Borrower and the
Guarantors and their assets, and not to any assets, or to the pledge of any assets, owned by any of the Oncor Subsidiaries, for the repayment of any amounts payable pursuant to this Agreement and for the satisfaction of any other Obligations and
(vi) that none of Oncor Holdings or the Oncor Subsidiaries shall be personally liable to the Guaranteed Parties for any amounts payable, or any other Obligation, under the Loan Documents. 
 (a) The Guaranteed Parties hereby acknowledge and agree that the Guaranteed Parties shall not (i) initiate any legal proceeding to procure the
appointment of an administrative receiver, or (ii) institute any bankruptcy, reorganization, insolvency, winding up, liquidation, or any like proceeding under applicable law, against any of the Oncor Holdings or the Oncor Subsidiaries, or
against any of Oncor Holdings’ or Oncor Subsidiaries’ assets. The Guaranteed Parties further acknowledge and agree that each of the Oncor Subsidiaries is a third party beneficiary of the foregoing covenant and shall have the right to
specifically enforce such covenant in any proceeding at law or in equity.
