Any Lender (an “Extending Lender”) wishing to have all or a portion of its Term Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class subject to such Extension Request converted into Extended Loans/Commitments shall notify the Administrative Agent (an “Extension Election”) on or prior to the date specified in such Extension Request of the amount of its Term Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class which it has elected to convert into Extended Loans/Commitments. In the event that the aggregate amount of Term Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments of the Existing Class subject to Extension Elections exceeds the amount of Extended Loans/Commitments requested pursuant to the Extension Request, Term Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments subject to Extension Elections shall be converted to Extended Loans/Commitments on a pro rata basis based on the amount of Term Loans, Revolving Credit Commitments, New Revolving Credit Commitments or Extended Revolving Credit Commitments included in each such Extension Election. Notwithstanding the conversion of any Existing Revolving Credit Commitment (other than a New Revolving Credit Commitment) into an Extended Revolving Credit Commitment, such Extended Revolving Credit Commitment shall be treated identically to all other Old Revolving Credit Commitments for purposes of the obligations of a Revolving Credit Lender in respect of Swingline Loans under Section 2.1(e) and Revolving Letters of Credit under Article 3, except that the applicable Extension Amendment may provide that the Swingline Maturity Date and/or the Revolving Letter of Credit Maturity Date may be extended and the related obligations to make Swingline Loans and issue Revolving Letters of Credit may be continued so long as the Swingline Lender and/or the applicable Revolving Letter of Credit Issuer, as applicable, have consented to such extensions (it being understood that no consent of any other Lender shall be required in connection with any such extension).

(c) Extended Loans/Commitments shall be established pursuant to an amendment (an “Extension Amendment”) to this Credit Agreement (which, except to the extent expressly contemplated by the penultimate sentence of this Section 2.15(c) and notwithstanding anything to the contrary set forth in Section 13.1, shall not require the consent of any Lender other than the Extending Lenders with respect to the Extended Loans/Commitments established thereby) executed by the Loan Parties, the Administrative Agent and the Extending Lenders. No Extension Amendment shall provide for any

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

(d) Notwithstanding anything to the contrary contained in this Agreement, (A) on any date on which any Existing Term Loan Class or Class of Existing Revolving Credit Commitments is converted to extend the related scheduled maturity date(s) in accordance with paragraph (a) above (an “Extension Date”), (I) in the case of the existing Term Loans of each Extending Lender, the aggregate principal amount of such existing Term Loans shall be deemed reduced by an amount equal to the aggregate principal amount of Extended Term Loans so converted by such Lender on such date, and the Extended Term Loans shall be established as a separate Class of Term Loans (together with any other Extended Term Loans so established on such date), and (II) in the case of the

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

(a)(i) If a Lender becomes, and during the period it remains, a Defaulting Lender and any Revolving Letter of Credit Exposure exists at the time a Lender becomes a Defaulting Lender, then the Revolving Letter of Credit Exposure of such Defaulting Lender will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Revolving Credit Commitment Percentage; provided that (a) each Non-Defaulting Lender’s Revolving Credit Exposure may not in any event exceed the Revolving Credit Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (b) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Revolving Letter of Credit Issuers, or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender.

(ii) If any Lender becomes, and during the period it remains, a Defaulting Lender, if any Revolving Letter of Credit is at the time outstanding, to the extent that all or any portion (the “unreallocated portion”) of the Defaulting Lender’s Revolving Letter of Credit Exposure cannot, or can only partially, be so reallocated to Non-Defaulting Lenders, whether by reason of the first proviso in Section 2.16(a)(i) above or otherwise, the applicable Revolving Letter of Credit Issuer may, by notice to the Borrower and such Defaulting Lender through the Administrative Agent, require the Borrower to Cash Collateralize, within 2 Business Days after notice is received by the Borrower, the obligations of the Borrower to the applicable Revolving Letter of Credit Issuer in respect of such Revolving Letter of Credit in an amount equal to the unreallocated portion of such Defaulting Lender’s Revolving Letter of Credit Exposure, unless the Borrower has made other arrangements reasonably satisfactory to such Revolving Letter of Credit Issuer, in

its reasonable discretion to protect it against the risk of non-payment by such Defaulting Lender.

(b) If any Lender becomes, and during the period it remains, a Defaulting Lender, no Revolving Letter of Credit Issuer will be required to issue any new Revolving Letter of Credit or to amend any outstanding Revolving Letter of Credit to increase the face amount thereof, alter the drawing terms thereunder or extend the expiry date thereof, unless the applicable Revolving Letter of Credit Issuer is reasonably satisfied that any exposure that would result from the exposure to such Defaulting Lender is eliminated or fully covered by the Revolving Credit Commitments of the Non-Defaulting Lenders or by Cash Collateralization or a combination thereof in accordance with clause (a) above or otherwise in a manner reasonably satisfactory to the applicable Revolving Letter of Credit Issuer.

(c) If the Borrower, the Administrative Agent and the Revolving Letter of Credit Issuers agree in writing in their discretion that a Lender that is a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon, as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will cease to be a Defaulting Lender and will be a Non-Defaulting Lender and any applicable Cash Collateral shall be promptly returned to the Borrower and any Revolving Letter of Credit Exposure of such Lender reallocated pursuant to Section 2.16(a) shall be reallocated back to such Lender; provided that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender.

(d) The Borrower, the Administrative Agent and the Swingline Lender may from time to time enter into arrangements or agreements (including cash collateral arrangements) amongst themselves in order to eliminate or alleviate the Swingline Lender's risk of non-payment by a Defaulting Lender and also to provide for Swingline Lender resignation and succession provisions in addition to those set forth in Section 2.1(e)(iii). Any such arrangement or agreement shall be deemed to be a Credit Document for purposes of this Agreement.”

(v) Section 3.8(c) of the Credit Agreement is hereby deleted and replaced with the following:

“(c) For purposes of this Agreement, “Cash Collateralize” means to pledge and deposit with or deliver to the Administrative Agent, for the benefit of the Revolving Letter of Credit Issuers or Swingline Lender, as applicable, as collateral for the Revolving L/C Obligations and Revolving Credit Lender reimbursement obligations in respect of Swingline Loans, as the case may be, cash or deposit account balances (“Cash Collateral”) in an amount equal to 100% of the amount of the Revolving Letters of Credit Outstanding or Swingline Loans, as the case may be, required to be Cash Collateralized pursuant to documentation in form and substance reasonably satisfactory to the Administrative Agent and the Revolving Letter of Credit Issuers or Swingline Lender, as the case

may be (which documents are hereby consented to by the Revolving Credit Lenders). Derivatives of such terms have corresponding meanings. The Borrower hereby grants to the Administrative Agent, for the benefit of the Revolving Letter of Credit Issuers and the Swingline Lender, as applicable, a security interest in all such cash, deposit accounts and all balances therein and all proceeds of the documentation in form and substance reasonably satisfactory to the Administrative Agent, the Revolving Letter of Credit Issuers and the Swingline Lender (which documents are hereby consented to by the Revolving Credit Lenders). Such cash collateral shall be maintained in blocked, interest bearing deposit accounts established by and in the name of the Administrative Agent.”

(w) Clause (a) of the first proviso in Section 4.2(a) of the Credit Agreement is hereby deleted and replaced in its entirety as follows:

“(a) any such reduction shall apply proportionately and permanently to reduce the Revolving Credit Commitments, as applicable, of each of the Revolving Credit Lenders, except that, notwithstanding the foregoing, in connection with the establishment on any date of any Extended Revolving Credit Commitments pursuant to Section 2.15, the Revolving Credit Commitments of any one or more Lenders providing any such Extended Revolving Credit Commitments on such date shall be reduced in an amount equal to the amount of Revolving Credit Commitments so extended on such date (provided that (x) after giving effect to any such reduction and to the repayment of any Revolving Credit Loans made on such date, the Revolving Credit Exposure of any such Lender does not exceed the Revolving Credit Commitment thereof (such Revolving Credit Exposure and Revolving Credit Commitment being determined in each case, for the avoidance of doubt, exclusive of such Lender’s Extended Revolving Credit Commitment and any exposure in respect thereof) and (y) for the avoidance of doubt, any such repayment of Revolving Credit Loans contemplated by the preceding clause shall be made in compliance with the requirements of Section 5.3(a) with respect to the ratable allocation of payments hereunder, with such allocation being determined after giving effect to any conversion pursuant to Section 2.15 of Revolving Credit Commitments and Revolving Credit Loans into Extended Revolving Credit Commitments and Extended Revolving Credit Loans pursuant to Section 2.15 prior to any reduction being made to the Revolving Credit Commitment of any other Lender)”

(x) The antepenultimate sentence of Section 5.1(a) is deleted and replaced with the following:

“Each prepayment in respect of any tranche of Term Loans pursuant to this Section 5.1 shall be (a) applied to the Class or Classes of Term Loans in such manner as the Borrower may determine and (b) applied to reduce Initial Term Loan Repayment Amounts, Delayed Draw Term Loan Repayment Amounts, Extended Term Loan Repayment Amounts and/or Incremental Term Loan Repayment Amounts, as the case may be, in each case in such order as the Borrower may determine; provided the Borrower may not prepay (i) Extended Term Loans of any Extension Series pursuant to this Section 5.1 unless such prepayment is accompanied by at least a pro rata prepayment of Term Loans of the Existing Term Loan Class from which such Extended Term Loans were converted (or such Term Loans of the Existing Term Loan Class have otherwise been repaid in

full). For the avoidance of doubt, the Borrower may prepay Term Loans of an Existing Term Loan Class pursuant to this Section 5.1 without any requirement to prepay Extended Term Loans that were converted from such Existing Term Loan Class.”

“; provided that, with respect to the Net Cash Proceeds of an Asset Sale Prepayment Event, Recovery Prepayment Event or Permitted Sale Leaseback, in each case solely to the extent with respect to any Collateral, the Borrower may use a portion of such Net Cash Proceeds to prepay or repurchase Permitted Other Debt (and with such prepaid or repurchased Permitted Other Debt permanently extinguished) with a Lien on the Collateral ranking pari passu with the Liens securing the Obligations to the extent any applicable Permitted Other Debt Document requires the issuer of such Permitted Other Debt to prepay or make an offer to purchase such Permitted Other Debt with the proceeds of such Prepayment Event, in each case in an amount not to exceed the product of (x) the amount of such Net Cash Proceeds multiplied by (y) a fraction, the numerator of which is the outstanding principal amount of the Permitted Other Debt with a Lien on the Collateral ranking pari passu with the Liens securing the Obligations and with respect to which such a requirement to prepay or make an offer to purchase exists and the denominator of which is the sum of the outstanding principal amount of such Permitted Other Debt and the outstanding principal amount of Term Loans.”; and

“(iii) On each occasion that a Debt Incurrence Prepayment Event occurs, the Borrower shall, within three Business Days after the receipt of the Net Cash Proceeds from the occurrence of such Debt Incurrence Prepayment Event, at the Borrower’s election, (x) prepay Term Loans in accordance with clauses (c) and (d) below, or (y) prepay Revolving Credit Loans, Extended Revolving Credit Loans and New Revolving Credit Loans (and correspondingly permanently reduce and terminate the related Revolving Credit Commitments, Extended Revolving Commitments or New Revolving Credit Commitments, as the case may be) in accordance with clause (e) below, in a principal amount equal to 100% of the Net Cash Proceeds from such Debt Incurrence Prepayment Event.”

(z) Section 5.2(c) of the Credit Agreement is hereby deleted and replaced with the following:

“(c) Application to Repayment Amounts. Subject to Section 5.2(h), each prepayment of Term Loans required by Sections 5.2(a)(i), (ii) and (iii) shall be allocated pro rata among the Initial Term Loans, the Delayed Draw Term Loans, the Incremental Term Loans, and the Extended Term Loans based upon the applicable remaining Repayment Amounts due in respect thereof and be applied to reduce the scheduled Repayment Amounts in direct order of maturity; provided that, subject to the pro rata application to Repayment Amounts within any Class of Term Loans, the Borrower may allocate such

prepayment in its sole discretion among the Class or Classes of Term Loans as the Borrower may specify, subject only to the following limitations: (i) the Borrower shall not allocate to Extended Term Loans of any Extension Series any mandatory prepayment (1) made pursuant to Section 5.2(a)(ii) unless such prepayment is accompanied by at least a pro rata prepayment, based upon the applicable remaining Repayment Amounts due in respect thereof, of Term Loans of the Existing Term Loan Class, if any, from which such Extended Term Loans were converted (or such Term Loans of the Existing Term Loan Class have otherwise been repaid in full) or (2) made pursuant to Section 5.2(a)(iii)unless all Initial Term Loans and Delayed Draw Term Loans have been repaid in full; (ii) the Borrower may not allocate any mandatory prepayments made pursuant to Section 5.2(a)(i) to any Class of Term Loans unless such prepayment is accompanied by a pro rata repayment, based upon the applicable remaining Repayment Amounts due in respect thereof, of Term Loans of the Existing Term Loan Class, if any, from which such Class of Term Loans was converted and Extended Term Loans, if any, that were originally converted from such Class of Term Loans (or the Existing Term Loan Class, if any, from which such Class of Term Loans was converted); and (iii) prepayments within any Class of Term Loans must be applied (1) pro rata to Repayment Amounts within any Class of Term Loans and (2) to reduce the scheduled Repayment Amounts in direct order of maturity. Subject to Section 5.2(h), with respect to each such prepayment, the Borrower will, not later than the date specified in Section 5.2(a) for making such prepayment, give the Administrative Agent telephonic notice (promptly confirmed in writing and which shall include a calculation of the amount of such prepayment to be applied to each Class of Term Loans) requesting that the Administrative Agent provide notice of such prepayment to each Lender of Term Loans.”

(aa) Section 5.2(d) of the Credit Agreement is hereby amended by deleting each occurrence of the phrase “Sections 5.2(a)(i) and (ii)” and “Section 5.2(a)(i) and (ii)” and replacing it with “Section 5.2(a)”.

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.

(ii) With respect to each mandatory reduction and termination of Revolving Credit Commitments, Extended Revolving Credit Commitments and New Revolving

Credit Commitments required by Section 5.2(a)(iii) or Section 10.1(y)(ii), the Borrower may designate (A) the Classes of Commitments to be reduced and terminated and (B) the corresponding Classes of Loans to be prepaid; provided that (x) any such reduction and termination shall apply proportionately and permanently to reduce the Commitments of each of the Lenders within any such Class, (y) no such reduction and termination of Old Revolving Credit Commitments (and prepayment of Loans accompanying a corresponding permanent reduction in Old Revolving Credit Commitments) shall be permitted unless all earlier maturing Old Revolving Credit Commitments (and Loans related to such Old Revolving Credit Commitments) shall have been terminated and repaid in full and (z) after giving effect to such termination or reduction and to any prepayments of Loans or cancellation or cash collateralization of letters of credit made on the date of each such reduction and termination in accordance with this Agreement, the aggregate amount of such Lenders’ credit exposures shall not exceed the remaining Commitments of such Lenders’ in respect of the Class reduced and terminated.

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 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.

(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.

(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.

(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.

(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 Loan Documents, 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 or any Financing Document (other than a Security Document) governing Additional Obligations unless such document otherwise provides) without the consent of any other Secured Party; provided 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 to 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 (it being understood that the undertaking of any transactions permitted by Section 5.6 (as in effect on the date hereof) shall not be deemed to materially and adversely

effect the Secured Commodity Hedge Counterpart), 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”, “Secured 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, (i) no amendment, modification, waiver, supplement, termination or consent shall be made or given with respect to this Agreement or any Security Document including any intercreditor agreement entered into by the Collateral Agent pursuant to the authority granted under Section 7.9 which has the effect of disproportionately disadvantaging, or otherwise discriminating against, the Secured Commodity Hedge Counterparties relative to the other Secured Parties 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.

(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 (or the Discharge of Secured Obligations other than Additional 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 (or the Discharge of Secured Obligations other than Additional Obligations), as applicable, 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/or (or the Discharge of Secured Obligations other than Additional 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”, “Letters of Credit”, “Commitments”, “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 with any amendment and restatement or Refinancing, the Liens securing the Secured Commodity Hedge Counterparties and, if set forth in the applicable Financing Documents, the holders of Additional Obligations 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 (including the Outstanding Amount (calculated both with and without giving effect to the proviso to the definition of such term)) that have been so 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 or any other Secured Debt Representative 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 or such other Secured Debt Representative has received a written notice of such Event of Default from any other Agent or any other such Secured Debt Representative, the Borrower, the other Loan Parties or any other Secured Party for whom such Agent or such Secured Debt Representative is acting as representative, 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 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 (including any Cash Collateral Accounts) are established in connection with cash collateralizing Letters of Credit or Swingline Loans as contemplated by the definition of Discharge of Secured Obligations and the definition of Discharge of Credit Agreement Obligations or as otherwise contemplated by the Financing Documents, such cash 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 or Swingline Loans 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.

(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, trustee or representative 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 (including those requirements set forth in Section 8.18 of the Security Agreement) 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 (and the agent, trustee or representative acting on behalf of such holder) incurred by US Holdings, 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 US Holdings, the Borrower or the relevant Subsidiary Guarantor intends, as applicable,

(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.

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 Secured Parties) 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 or Discharge of Credit Agreement Obligations, as applicable, 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 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.

(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.

(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 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.

(a) 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 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 Security 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 Secured Debt Representatives.

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 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 or their Secured Debt Representatives 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 (or their Secured Debt Representative) 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 Financing 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 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.

(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.

(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 the Guarantee may be exercised solely by the Collateral Agent 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 Other Intercreditor Agreements. The Collateral Agent is hereby authorized without the further consent of the Secured Parties to negotiate, execute and deliver on behalf of the Secured Parties (x) any intercreditor agreement in respect of Alternate First Lien Collateral and (y) any intercreditor agreement in respect of liens securing obligations on all or any portion of the Collateral with a priority junior to that of the Secured Parties hereunder; provided that in each case, the entering into of such agreement (and the incurrence of such obligations and liens) is 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 provided further, that any such intercreditor agreement is on terms substantially similar to this Agreement (in the case of an intercreditor agreement referenced in subclause (x) above) or Exhibit R of the Credit Agreement (as of the date hereof) (in the case of an intercreditor agreement referenced in subclause (y) above) and in all cases, on any other terms which shall not have the effect of disproportionately disadvantaging, or otherwise discriminating against, the Secured Commodity Hedge Counterparties relative to the other Secured Parties unless the prior written consent of the Required Commodity Hedge Counterparties and the Required Alternative Commodity Hedge Counterparties shall have been obtained, or, if less than all of the Secured Commodity Hedge Counterparties are so disadvantaged or otherwise discriminated against, unless the prior written consent of each such Secured Commodity Hedge Counterparty that would be materially and adversely affected thereby shall have been obtained.

7.10 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 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 7.10. 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 7.10 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 7.10 shall survive the termination of this Agreement.

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.

(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 to manage and supervise their respective loans and extensions of credit under the Financing Documents in accordance with law and as they may otherwise, in their sole discretion, deem appropriate.

Except as otherwise expressly provided herein, the Secured Commodity Hedge Counterparty will be entitled to manage and supervise their respective transactions under their respective 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:

(b) except as otherwise expressly set forth in this Agreement, any change in the time, manner or place of payment of, or in any other 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;

leases and purchase money obligations to the extent subject to a Lien, in each case permitted by the Credit Agreement and by each Additional First Lien Agreement, and the terms of the Indebtedness secured by such Lien prohibit assignment of, or granting of a security interest in, such Grantor’s rights and interests therein (other than to the extent that any such prohibition would be rendered ineffective pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law), provided, that immediately upon the repayment of all Indebtedness secured by such Lien, such Grantor shall be deemed to have granted a Security Interest in all the rights and interests with respect to such property or assets, and (I) any assets as to which the Collateral Agent and the Company have determined that the costs or other consequences (including adverse tax consequences) of providing a security interest in is excessive in view of the benefits to be gained thereby by the Lenders and (y) none of the items included in clauses (i) through (xiv) above shall constitute Collateral to the extent (and only to the extent) that the grant of the Security Interest therein would violate any Requirement of Law applicable to such Collateral.

(b) Each Grantor hereby irrevocably authorizes the Collateral Agent and its Affiliates, counsel and other representatives, at any time and from time to time, to file or record financing statements, amendments to financing statements and, with notice to the Company, other filing or recording documents or instruments with respect to the Collateral in such form and in such offices as the Collateral Agent reasonably determines appropriate to perfect the security interests of the Collateral Agent under this Security Agreement, and such financing statements and amendments may describe the Collateral covered thereby as “all assets”, “all personal property” or words of similar effect; provided that, with respect to As-Extracted Collateral, the Collateral Agent shall only file or record financing statements in the Secretary of State or other central filing office of the jurisdiction of organization of a Grantor except in connection with a Mortgage. Each Grantor hereby also authorizes the Collateral Agent and its Affiliates, counsel and other representatives, at any time and from time to time, to file continuation statements with respect to previously filed financing statements.

Each Grantor hereby agrees to provide to the Collateral Agent, promptly upon request, any information reasonably necessary to effectuate the filings or recordings authorized by this Section 2(b).

The Collateral Agent is further authorized to file with the United States Patent and Trademark Office or United States Copyright Office (or any successor office) such documents as may be necessary or advisable for the purpose of perfecting, confirming, continuing, enforcing or protecting the Security Interest granted hereunder by each Grantor, without the signature of any Grantor, and naming any Grantor or the Grantors as debtors and the Collateral Agent (for the benefit of the First Lien Secured Parties), as the case may be, as secured party.

The Security Interests are granted as security only and shall not subject the Collateral Agent or any other First Lien Secured Party to, or in any way alter or modify, any obligation or liability of any Grantor with respect to or arising out of the Collateral.

(c) Notwithstanding anything to the contrary in this Section 2, at the Company’s option, the term Collateral, as it refers to the Collateral securing Additional First Lien Obligations, shall not include any Stock and other securities of a Subsidiary to the extent that the pledge of such Stock and other securities would result in the Company being required to file separate financial statements of such Subsidiary with the SEC, but only to the extent necessary to not be subject to such requirement and only for so long as such requirement is in existence and only with respect to the relevant Additional First Lien

Obligations affected; provided that neither US Holdings, the Company nor any Subsidiary shall take any action in the form of a reorganization, merger or other restructuring a principal purpose of which is to provide for the release of the Lien on any Stock pursuant to this clause (ii). In addition, in the event that Rule 3-16 of Regulation S-X under the Securities Act of 1933, as amended (“Rule 3-16”) is amended, modified or interpreted by the SEC to require (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would require) the filing with the SEC (or any other Governmental Authority) of separate financial statements of any Subsidiary of the Company due to the fact that such Subsidiary’s Stock secures the Additional First Lien Obligations affected thereby, then the Stock of such Subsidiary will automatically be deemed not to be part of the Collateral securing the relevant Additional First Lien Obligations affected thereby but only to the extent necessary to not be subject to such requirement and only for so long as required to not be subject to such requirement. In such event, this Security Agreement may be amended or modified, without the consent of any First Lien Secured Party, to the extent necessary to release the Security Interests in favor of the Collateral Agent on the shares of Stock that are so deemed to no longer constitute part of the Collateral for the relevant Additional First Lien Obligations only. In the event that Rule 3-16 is amended, modified or interpreted by the SEC to permit (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would permit) such Subsidiary’s Stock to secure the Additional First Lien Obligations in excess of the amount then pledged without the filing with the SEC (or any other Governmental Authority) of separate financial statements of such Subsidiary, then the Stock of such Subsidiary will automatically be deemed to be a part of the Collateral for the relevant Additional First Lien Obligations. For the avoidance of doubt and notwithstanding anything to the contrary in this Agreement, nothing in this clause (d) shall limit the pledge of such Stock and other securities from securing the Obligations (as defined in the Credit Agreement) at all times or from securing any Additional First Lien Obligations that are not in respect of securities subject to regulation by the SEC.

Each Grantor hereby represents and warrants to the Collateral Agent and each First Lien Secured Party that:

3.1. Title; No Other Liens. Except for (a) the Security Interest granted to the Collateral Agent for the benefit of the First Lien Secured Parties pursuant to this Security Agreement, (b) the Liens permitted under each of the Credit Agreement and each Additional First Lien Agreement and (c) any Liens securing Indebtedness which is no longer outstanding or any Liens with respect to commitments to lend which have been terminated, such Grantor owns each item of the Collateral free and clear of any and all Liens or claims of others. No security agreement, financing statement or other public notice with respect to all or any part of the Collateral that evidences a Lien securing any material Indebtedness is on file or of record in any public office, except such as (i) have been filed in favor of the Collateral Agent for the benefit of the First Lien Secured Parties pursuant to this Security Agreement or (ii) are permitted by each of the Credit Agreement and each Additional First Lien Agreement. For the avoidance of doubt, any reference herein to Liens permitted to be outstanding shall mean only Liens permitted to be outstanding under both the Credit Agreement (so long as it is in effect) and each Additional First Lien Agreement. The information set forth in the Perfection Certificate is complete and accurate in all respects as of the date hereof.

(a) This Security Agreement is effective to create in favor of the Collateral Agent, for its benefit and for the benefit of the First Lien Secured Parties, legal, valid and enforceable Security Interests in the Collateral, subject to the effects of bankruptcy, insolvency or similar laws affecting creditors’ rights generally and general equitable principles.

(b) Subject to the limitations set forth in clause (c) of this Section 3.2, the Security Interests granted pursuant to this Security Agreement (i) constitute and will continue to constitute valid and perfected Security Interests in the Collateral (as to which perfection may be obtained by the filings or other actions described in clause (A), (B), (C) or (D) of this paragraph, which actions have been taken prior to the date hereof to the extent required by the Original Security Agreement and shall continue to apply to the First Lien Obligations under this Security Agreement and other than with respect to any As-Extracted Collateral that requires the filing or recording of financing statements other than in the office of the Secretary of State or other central filing office in the jurisdiction of organization of the applicable Grantor in order to perfect) in favor of the Collateral Agent, for the benefit of the First Lien Secured Parties, as collateral security for the First Lien Obligations, as a result of (A) the completion of the filing in the applicable filing offices of all financing statements, in each case, naming each Grantor as “debtor” and the Collateral Agent as “secured party” and describing the Collateral, (B) delivery to the Collateral Agent (or its bailee) of all Instruments, Chattel Paper, Certificated Securities and negotiable Documents in each case, properly endorsed for transfer to the Collateral Agent or in blank, (C) delivery to the Collateral Agent of the fully executed Deposit Agreement and (D) completion of the filing, registration and recording of a fully executed agreement in the form hereof (or a supplement hereto) and containing a description of all Collateral constituting registered Patents and Trademarks in the United States Patent and Trademark Office (or any successor office) within a three month period (commencing as of the date of the Original Security Agreement) or, with respect to Collateral constituting United States Patents and United States registered Trademarks acquired after the date of the Original Security Agreement, within three months thereafter, and all Collateral constituting registered Copyrights in the United States Copyright Office (or any successor office) within a one month period (commencing as of the date of the Original Security Agreement) or, with respect to Collateral constituting registered United States Copyrights acquired after the date of the Original Security Agreement, within one month thereafter pursuant to 35 USC § 261, 15 USC § 1060 or 17 USC § 205 and the regulations thereunder, and otherwise as may be required pursuant to the laws of any other necessary jurisdiction to the extent that a security interest may be perfected by such filings, registrations and recordings, and (ii) are prior to all other Liens on the Collateral other than Liens permitted pursuant to Section 10.2 of the Credit Agreement and by the equivalent provisions of each Additional First Lien Agreement.

(c) Notwithstanding anything to the contrary herein, no Grantor shall be required to perfect the Security Interests granted by this Security Agreement by any means other than by (i) filings pursuant to the Uniform Commercial Code of the relevant State(s), (ii) filings approved by United States government offices with respect to Intellectual Property or (iii) delivery to the Collateral Agent (or its bailee) to be held in its possession of all Collateral consisting of Tangible Chattel Paper, Instruments, Certificated Securities or Negotiable Documents; provided that the Grantors shall not be required to deliver to the Collateral Agent any Tangible Chattel Paper, Instruments, Certificated Securities or Negotiable Documents with an individual fair market value of less than $10,000,000. Notwithstanding anything to the contrary herein, no Grantor shall be required to complete any filings or other actions with respect to the perfection of the security interests created hereby in any jurisdiction outside of the United States.

(d) It is understood and agreed that the Security Interests in Investment Property created hereunder shall not prevent the Grantors from using such assets in the ordinary course of their respective businesses.

3.3. Bundled Payments. As of the date hereof, it is not billing for, and has no, Bundled Payments.

Each Grantor hereby covenants and agrees with the Collateral Agent and the First Lien Secured Parties that, from and after the date of this Security Agreement until all Secured Obligations (other than contingent indemnification and reimbursement obligations) are paid in full, the Commitments are terminated and no Letters of Credit thereunder remains outstanding (or all such Letters of Credit shall have been cash collateralized):

(a) Such Grantor shall maintain the Security Interest created by this Security Agreement as a perfected Security Interest having at least the priority described in Section 3.1 and shall defend such Security Interest against the claims and demands of all Persons whomsoever, in each case subject to Section 3.2(c).

(b) Such Grantor will furnish to the Collateral Agent, the Lenders and any other First Lien Secured Parties from time to time statements and schedules further identifying and describing the assets and property of such Grantor and such other reports in connection therewith as the Collateral Agent may reasonably request. In addition, within 30 days after the end of each calendar quarter, such Grantor will deliver to the Collateral Agent a written supplement substantially in the form of Annex A hereto with respect to any additional Copyrights, Patents and Trademarks registered or applied for with the United States Patent and Trademark Office or the United States Copyright Office and acquired by such Grantor after the date hereof, all in reasonable detail.

(c) Subject to clause (d) below and Section 3.2(c), each Grantor agrees that at any time and from time to time, at the expense of such Grantor, it will execute any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements and other documents, including all applicable documents required under Section 3.2(b)(i)(C)), which may be required under any applicable law, or which the Collateral Agent or the Required Secured Parties may reasonably request, in order (i) to grant, preserve, protect and perfect the validity and priority of the Security Interests created or intended to be created hereby or (ii) to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral, including the filing of any financing or continuation statements under the Uniform Commercial Code in effect in any jurisdiction with respect to the Security Interests created hereby and all applicable documents required under Section 3.2(b)(i)(C), all at the expense of such Grantor.

(d) Notwithstanding anything in this Section 4.1 to the contrary, (i) with respect to any assets acquired by such Grantor after the date hereof that are required by the Credit Agreement or any Additional First Lien Agreement to be subject to the Lien created hereby or (ii) with respect to any Person that, subsequent to the date hereof, becomes a Domestic Subsidiary that is required by the Credit Agreement or any Additional First Lien Agreement to become a party hereto, the relevant Grantor after the

acquisition or creation thereof shall promptly take all actions required by the Credit Agreement, any Additional First Lien Agreement or this Section 4.1.

(e) The Collateral Agent has a first priority security interest in the Deposit L/C Loan Collateral Account which security interest is perfected by Control (as defined in Section 9-104 of the UCC). No Pledgor shall grant Control of the Deposit L/C Loan Collateral Account to any person other than the Collateral Agent and no Pledgor shall grant Control of any other Deposit Account to any other Person, except in connection with a Permitted Lien.

4.2. Changes in Locations, Name, etc. Each Grantor will furnish to the Collateral Agent promptly (and in any event within 30 days of such change) a written notice of any change (i) in its legal name, (ii) in its jurisdiction of organization or location for purposes of the UCC, (iii) in its identity or type of organization or corporate structure or (iv) in its Federal Taxpayer Identification Number or organizational identification number. Each Grantor agrees promptly to provide the Collateral Agent with certified organizational documents reflecting any of the changes described in the first sentence of this paragraph. Each Grantor also agrees promptly to notify the Collateral Agent if any material portion of the Collateral is damaged or destroyed.

4.3. Notices. Each Grantor will advise the Collateral Agent, the Lenders and each of the other First Lien Secured Parties promptly, in reasonable detail, of any Lien of which it has knowledge (other than the Security Interests created hereby or Liens permitted under each of the Credit Agreement and each Additional First Lien Agreement) on any of the Collateral which would adversely affect, in any material respect, the ability of the Collateral Agent to exercise any of its remedies hereunder.

4.4. Bundled Payments. From and after the date hereof, no Grantor shall voluntary include Bundled Payment Amounts in a bundled bill.

(a) At any time after the occurrence and during the continuance of an Event of Default and after giving reasonable written notice to the Company and any other relevant Grantor, the Applicable First Lien Representative shall have the right, but not the obligation, to instruct the Collateral Agent to (and upon such instruction, the Collateral Agent shall) make test verifications of the Accounts that are Collateral (the “Subject Accounts”) in any manner and through any medium that such Applicable First Lien Representative reasonably considers advisable, and each Grantor shall furnish all such assistance and information as such Applicable First Lien Representative may require in connection with such test verifications. The Collateral Agent shall have the absolute right to share any information it gains from such inspection or verification with any First Lien Secured Party.

(b) The Collateral Agent hereby authorizes each Grantor to collect such Grantor’s Subject Accounts and the Collateral Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required in writing by the Collateral Agent at any time after the occurrence and during the continuance of an Event of Default, any payments of Subject Accounts, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly endorsed by such Grantor to the Collateral Agent if required, in a Collateral Account maintained under the sole dominion and control

of and on terms and conditions reasonably satisfactory to the Collateral Agent, subject to withdrawal by the Collateral Agent for the account of the First Lien Secured Parties only as provided in Section 5.5, and (ii) until so turned over, shall be held by such Grantor in trust for the Collateral Agent and the First Lien Secured Parties, segregated from other funds of such Grantor. Each such deposit of Proceeds of Subject Accounts shall be accompanied by a report identifying in reasonable detail the nature and source of the payments included in the deposit.

(c) At the Collateral Agent’s written request at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall deliver to the Collateral Agent all original and other documents evidencing, and relating to, the agreements and transactions which gave rise to the Subject Accounts, including all original orders, invoices and shipping receipts.

(d) Upon the occurrence and during the continuance of an Event of Default, a Grantor shall not grant any extension of the time of payment of any of the Subject Accounts, compromise, compound or settle the same for less than the full amount thereof, release, wholly or partly, any Person liable for the payment thereof, or allow any credit or discount whatsoever thereon if the Collateral Agent shall have instructed the such Grantor in writing not to grant or make any such extension, credit, discount, compromise or settlement under any circumstances during the continuance of such Event of Default.

(e) At the direction of the Collateral Agent, upon the occurrence and during the continuance of an Event of Default, each Grantor shall grant to the Collateral Agent to the extent assignable, an irrevocable, non-exclusive, fully paid-up, royalty-free, worldwide license to use, assign, license or sublicense any of the Intellectual Property now owned or hereafter acquired by such Grantor. Such license shall include access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation of printout thereof.

(a) The Collateral Agent in its own name or in the name of others may at any time after the occurrence and during the continuance of an Event of Default, after giving reasonable written notice to the relevant Grantor of its intent to do so, communicate with obligors under the Subject Accounts to verify with them to the Collateral Agent’s satisfaction the existence, amount and terms of any Subject Accounts. The Collateral Agent shall have the absolute right to share any information it gains from such inspection or verification with any First Lien Secured Party.

(b) Upon the written request of the Collateral Agent at any time after the occurrence and during the continuance of an Event of Default, each Grantor shall notify obligors on the Subject Accounts that the Subject Accounts have been assigned to the Collateral Agent for the benefit of the First Lien Secured Parties and that payments in respect thereof shall be made directly to the Collateral Agent.

(c) Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each of the Subject Accounts to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with the terms of any agreement giving rise thereto. Neither the Collateral Agent nor any First Lien Secured Party shall have any obligation or liability under any Subject Account (or any agreement giving rise thereto) by reason of or arising out of this Security Agreement or the receipt by the Collateral Agent or any First Lien Secured Party of any payment relating thereto, nor shall the Collateral Agent or any First Lien Secured Party be obligated in any manner to perform any of the obligations of any Grantor under or pursuant to any Subject Account (or any

agreement giving rise thereto), to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party thereunder, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

5.3. Proceeds to be Turned Over to Collateral Agent. In addition to the rights of the Collateral Agent and the First Lien Secured Parties specified in Section 5.1 with respect to payments of Subject Accounts, if an Event of Default shall occur and be continuing and the Collateral Agent so requires by notice in writing to the relevant Grantor (it being understood that the exercise of remedies by the First Lien Secured Parties pursuant to the Intercreditor Agreement in connection with an Event of Default under Section 11.5 of the Credit Agreement or the equivalent provisions of any Additional First Lien Agreement shall be deemed to constitute a request by the Collateral Agent for the purposes of this sentence and in such circumstances, no such written notice shall be required), all Proceeds received by any Grantor consisting of cash, checks and other near-cash items shall be held by such Grantor in trust for the Collateral Agent and the First Lien Secured Parties, segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to the Collateral Agent in the exact form received by such Grantor (duly endorsed by such Grantor to the Collateral Agent, if required). All Proceeds received by the Collateral Agent hereunder shall be held by the Collateral Agent in a Collateral Account maintained under its dominion and control and on terms and conditions reasonably satisfactory to the Collateral Agent. All Proceeds while held by the Collateral Agent in a Collateral Account (or by such Grantor in trust for the Collateral Agent and the First Lien Secured Parties) shall continue to be held as collateral security for all the First Lien Obligations and shall not constitute payment thereof until applied as provided in Section 5.4.

5.4. Application of Proceeds. The Collateral Agent shall apply the proceeds of any collection or sale of the Collateral as well as any Collateral consisting of cash, at any time after receipt in the order specified in Section 4.1 of the Intercreditor Agreement. Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

5.5. Code and Other Remedies. If an Event of Default shall occur and be continuing, the Collateral Agent may exercise in respect of the Collateral, in addition to all other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC or any other applicable law and also may, with notice to the relevant Grantor, sell the Collateral or any part thereof in one or more parcels at one or more public or private sales, at any exchange, broker’s board or office of the Collateral Agent or any Lender or elsewhere for cash or on credit or for future delivery at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral. The Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or

may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Collateral Agent and any First Lien Secured Party shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase the whole or any part of the Collateral so sold, and, subject to the terms of the Intercreditor Agreement, the Collateral Agent or such First Lien Secured Party may pay the purchase price by crediting the amount thereof against the First Lien Obligations. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Grantor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, each Grantor hereby waives any claim against the Collateral Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree. Each Grantor further agrees, at the Collateral Agent’s request to assemble the Collateral and make it available to the Collateral Agent, at places which the Collateral Agent shall reasonably select, whether at such Grantor’s premises or elsewhere. The Collateral Agent shall apply the net proceeds of any action taken by it pursuant to this Section 5.5 in accordance with the provisions of Section 5.4.

5.6. Deficiency. Each Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay its First Lien Obligations and the reasonable and documented fees, disbursements and other charges of one firm of counsel and, if necessary, one firm of regulatory counsel and/or one firm of local counsel in each appropriate jurisdiction, to the Administrative Agent and Collateral Agent (and, in the case of an actual or perceived conflict of interest where the Person affected by such conflict informs the Company of such conflict and thereafter, after receipt of the consent of the Company (which consent shall not be unreasonably withheld or delayed), retains its own counsel, of another firm of counsel for such affected Person) to collect such deficiency.

5.7. Amendments, etc. with Respect to the First Lien Obligations; Waiver of Rights. Each Grantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Grantor and without notice to or further assent by any Grantor, (a) any demand for payment of any of the First Lien Obligations made by the Collateral Agent or any other First Lien Secured Party may be rescinded by such party and any of the First Lien Obligations continued, (b) the First Lien Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Collateral Agent or any other First Lien Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit, any Additional First Lien Agreement and any other documents executed and delivered in connection therewith and any Secured Cash Management Agreements, Secured Hedging Agreements, and Secured Commodity Hedging Agreement and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement, the applicable Cash Management Bank or Hedge Bank, or, in the case of any Additional First Lien Agreement, the trustee, agent or representative thereunder or the required lenders or holders thereunder) may deem advisable from time to time, and (d) any collateral security, guarantee or right of offset at any time held by the Collateral Agent or any other First Lien Secured Party for the payment of the First Lien Obligations may be sold, exchanged, waived, surrendered or released. Neither the Collateral Agent nor any

other First Lien Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the First Lien Obligations or for this Security Agreement or any property subject thereto. When making any demand hereunder against any Grantor, the Collateral Agent or any other First Lien Secured Party may, but shall be under no obligation to, make a similar demand on the Company or any Grantor or any other Person, and any failure by the Collateral Agent or any other First Lien Secured Party to make any such demand or to collect any payments from the Company or any Grantor or any other Person or any release of the Company or any Grantor or any other Person shall not relieve any Grantor in respect of which a demand or collection is not made or any Grantor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Collateral Agent or any other First Lien Secured Party against any Grantor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

(a) Each Grantor hereby appoints, which appointment is irrevocable and coupled with an interest, effective upon the occurrence and during the continuance of an Event of Default, the Collateral Agent and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, for the purpose of carrying out the terms of this Security Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, and, without limiting the generality of the foregoing, each Grantor hereby gives the Collateral Agent the power and right, on behalf of such Grantor, either in the Collateral Agent’s name or in the name of such Grantor or otherwise, without assent by such Grantor, to do any or all of the following, in each case after the occurrence and during the continuance of an Event of Default and after written notice by the Collateral Agent of its intent to do so:

(i) take possession of and endorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Subject Account or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Collateral Agent for the purpose of collecting any and all such moneys due under any Subject Account or with respect to any other Collateral whenever payable;

(ii) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Collateral Agent may reasonably request to evidence the Collateral Agent’s and the First Lien Secured Parties’ Security Interest in such Intellectual Property and the goodwill and general intangibles of such Grantor relating thereto or represented thereby;

(iii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral;

(iv) execute, in connection with any sale provided for in Section 5.5, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral;

(vi) direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Collateral Agent or as the Collateral Agent shall direct;

(vii) ask or demand for, collect and receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral;

(viii) sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral;

(ix) commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any portion thereof and to enforce any other right in respect of any Collateral;

(x) defend any suit, action or proceeding brought against such Grantor with respect to any Collateral (with such Grantor’s consent to the extent such action or its resolution could materially affect such Grantor or any of its Affiliates in any manner other than with respect to its continuing rights in such Collateral);

(xi) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Collateral Agent may deem appropriate (with such Grantor’s consent to the extent such action or its resolution could materially affect such Grantor or any of its affiliates in any manner other than with respect to its continuing rights in such Collateral);

(xii) assign any Intellectual Property (along with the goodwill of the business to which any such Intellectual Property pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Collateral Agent shall in its reasonable business discretion determine; and

(xiii) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Collateral Agent were the absolute owner thereof for all purposes, and do, at the Collateral Agent’s option and such Grantor’s expense, at any time, or from time to time, all acts and things that the Collateral Agent deems necessary to protect, preserve or realize upon the Collateral and the Collateral Agent’s and the First Lien Secured Parties’ Security Interests therein and to effect the intent of this Security Agreement, all as fully and effectively as such Grantor might do.

Anything in this Section 6.1(a) to the contrary notwithstanding, the Collateral Agent agrees that it will not exercise any rights under the power of attorney provided for in this Section 6.1(a) unless an Event of Default shall have occurred and be continuing.

(b) If any Grantor fails to perform or comply with any of its agreements contained herein, the Collateral Agent, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The expenses of the Collateral Agent incurred in connection with actions undertaken as provided in this Section 6.1 (to the extent required to be reimbursed by the Grantors pursuant to the Credit Documents), together with interest thereon at a rate per annum equal to the highest rate per annum at which interest would then be payable on any category of past due ABR Loans under the Credit Agreement (whether or not the Credit Agreement is then in effect), from the date of payment by the Collateral Agent to the date reimbursed by the relevant Grantor, shall be payable by such Grantor to the Collateral Agent on demand.

(d) Each Grantor hereby ratifies all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Security Agreement are coupled with an interest and are irrevocable until this Security Agreement is terminated and the Security Interests created hereby are released.

6.2. Duty of Collateral Agent. The Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property. Neither the Collateral Agent, any First Lien Secured Party nor any of their respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The powers conferred on the Collateral Agent and the First Lien Secured Parties hereunder are solely to protect the Collateral Agent’s and the First Lien Secured Parties’ interests in the Collateral and shall not impose any duty upon the Collateral Agent or any First Lien Secured Party to exercise any such powers. The Collateral Agent and the First Lien Secured Parties shall be accountable only for amounts that they actually receive as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

6.3. Authority of Collateral Agent. Each Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Security Agreement with respect to any action taken by the Collateral Agent or the exercise or non-exercise by the Collateral Agent of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Security Agreement shall, as between the Collateral Agent and the First Lien Secured Parties, be governed by the Intercreditor Agreement, and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantors, the Collateral Agent shall be conclusively presumed to be acting as agent for the applicable First Lien Secured Parties with full and valid authority so to act or refrain from acting, and no Grantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

6.4. Security Interest Absolute. All rights of the Collateral Agent hereunder, the Security Interest and all obligations of the Grantors hereunder shall be absolute and unconditional.

6.5. Continuing Security Interest; Assignments Under the Credit Agreement; Release.

(a) This Security Agreement shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Grantor and the successors and assigns thereof and shall inure to the benefit of the Collateral Agent and the other First Lien Secured Parties and their respective successors, indorsees, transferees and assigns until all Secured Obligations (other than any contingent indemnity obligations not then due) and the obligations of each Grantor under this Security Agreement shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding (or all such Letters of Credit shall have been fully Cash Collateralized or otherwise back-stopped to the reasonable satisfaction of the applicable Letter of Credit Issuers), notwithstanding that from time to time during the term of the Credit Agreement, any Additional First Lien Agreements and any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement the Credit Parties may be free from any First Lien Obligations.

(b) Subject to the terms of the Intercreditor Agreement, a Subsidiary Grantor shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Subsidiary Grantor shall be automatically released (x) as it relates to the “Obligations” (as defined in the Credit Agreement), upon the consummation of any transaction permitted under the Credit Agreement as a result of which such Subsidiary Grantor ceases to be a Subsidiary Guarantor and (y) as it relates to the First Lien Obligations under any Additional First Lien Agreement, upon the consummation of any transaction permitted under such Additional First Lien Agreement, as a result of which such Subsidiary Guarantor ceases to be a guarantor under such Additional First Lien Agreement pursuant to the applicable provision(s) of such Additional First Lien Agreement.

(c) Subject to the terms of the Intercreditor Agreement, the Security Interest granted hereby in any Collateral shall automatically be released (i) if (and to the extent) provided in (A) Section 13.1 of the Credit Agreement and (B) any applicable provision of any Additional First Lien Agreement, (ii) upon the effectiveness of any written consent to the release of the security interest granted hereby in such Collateral pursuant to Section 13.1 of the Credit Agreement and any applicable provision of any Additional First Lien Agreement and (iii) as otherwise may be provided in the Intercreditor Agreement. Any such release in connection with any sale, transfer or other disposition of such Collateral shall result in such Collateral being sold, transferred or disposed of, as applicable, free and clear of the Lien and Security Interest created hereby.

(d) In connection with any termination or release pursuant to paragraph (a), (b) or (c), the Collateral Agent shall execute and deliver to any Grantor, at such Grantor’s expense, all documents that such Grantor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 6.5 shall be without recourse to or warranty by the Collateral Agent.

6.6. Reinstatement. Each Grantor further agrees that, if any payment made by any Credit Party or other Person and applied to the First Lien Obligations is at any time annulled, avoided, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the Proceeds of Collateral are required to be returned by any First Lien Secured Party to such Credit Party, its estate, trustee, receiver or any other party, including any Grantor, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, any Lien or other Collateral securing such liability shall be and remain in full force and effect, as fully as if such payment had never been made or, if prior thereto the Lien granted hereby or other

Collateral securing such liability hereunder shall have been released or terminated by virtue of such cancellation or surrender), such Lien or other Collateral shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect any Lien or other Collateral securing the obligations of any Grantor in respect of the amount of such payment.

(a) Citibank, N.A. has been appointed to act as the Collateral Agent under the Credit Agreement, by the Lenders under the Credit Agreement and, by their acceptance of the benefits hereof, the other First Lien Secured Parties. The Collateral Agent shall be obligated, and shall have the right hereunder, to make demands, to give notices, to exercise or refrain from exercising any rights, and to take or refrain from taking any action (including the release or substitution of Collateral), solely in accordance with this Security Agreement, the Credit Agreement and the Intercreditor Agreement, provided that the Collateral Agent shall exercise, or refrain from exercising, any remedies provided for in Section 5 in accordance with the instructions of the Required Secured Parties. In furtherance of the foregoing provisions of this Section 7(a), each First Lien Secured Party, by its acceptance of the benefits hereof, agrees that it shall have no right individually to realize upon any of the Collateral hereunder, it being understood and agreed by such First Lien Secured Party that all rights and remedies hereunder may be exercised solely by the Collateral Agent for the benefit of the applicable First Lien Secured Parties in accordance with the terms of this Section 7(a).

(b) The Collateral Agent shall at all times be the same Person that is the Collateral Agent under the Credit Agreement. Written notice of resignation by the Collateral Agent pursuant to Section 12.9 of the Credit Agreement shall also constitute notice of resignation as Collateral Agent under this Security Agreement; removal of the Collateral Agent shall also constitute removal under this Security Agreement; and appointment of a Collateral Agent pursuant to Section 12.9 of the Credit Agreement shall also constitute appointment of a successor Collateral Agent under this Security Agreement. Upon the acceptance of any appointment as Collateral Agent under Section 12.9 of the Credit Agreement by a successor Collateral Agent, that successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring or removed Collateral Agent under this Security Agreement, and the retiring or removed Collateral Agent under this Security Agreement shall promptly (i) transfer to such successor Collateral Agent all sums, securities and other items of Collateral held hereunder, together with all records and other documents necessary or appropriate in connection with the performance of the duties of the successor Collateral Agent under this Security Agreement, and (ii) execute and deliver to such successor Collateral Agent or otherwise authorize the filing of such amendments to financing statements and take such other actions, as may be necessary or appropriate in connection with the assignment to such successor Collateral Agent of the Security Interests created hereunder, whereupon such retiring or removed Collateral Agent shall be discharged from its duties and obligations under this Security Agreement. After any retiring or removed Collateral Agent’s resignation or removal hereunder as Collateral Agent, the provisions of this Security Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it under this Security Agreement while it was Collateral Agent hereunder.

(c) The Collateral Agent shall not be deemed to have any duty whatsoever with respect to any First Lien Secured Party that is a counterparty to a Secured Cash Management Agreement, Secured Commodity Hedging Agreement or Secured Hedging Agreement the obligations under which constitute First Lien Obligations, unless it shall have received written notice in form and substance satisfactory to the Collateral Agent from a Grantor or any such First Lien Secured Party as to the existence and terms of the applicable Secured Cash Management Agreement, Secured Commodity Hedging

Agreement or Secured Hedging Agreement, it being agreed by the Collateral Agent that delivery of a duly executed Accession Agreement pursuant to the terms of the Intercreditor Agreement shall comply with the requirements of this clause (c).

8.1. Amendments in Writing. None of the terms or provisions of this Security Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the affected Grantor and the Collateral Agent in accordance with Section 13.1 of the Credit Agreement and by each other party to the extent required by (and in accordance with) the Intercreditor Agreement.

8.2. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 13.2 of the Credit Agreement (whether or not then in effect).

8.3. No Waiver by Course of Conduct; Cumulative Remedies. Neither the Collateral Agent nor any First Lien Secured Party shall by any act (except by a written instrument pursuant to Section 8.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any other First Lien Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any other First Lien Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Collateral Agent or such other First Lien Secured Party would otherwise have on any future occasion. The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

(a) Each Grantor agrees to pay any and all reasonable and documented out-of-pocket costs and expenses (including all reasonable and documented fees, disbursements and other charges of one firm of counsel, and, if necessary, one firm of regulatory counsel and/or one firm of local counsel in each appropriate jurisdiction, in each case to the Administrative Agent and Collateral Agent (and, in the case of an actual or perceived conflict of interest where the Person affected by such conflict informs the Company of such conflict and thereafter, after receipt of the consent of the Company (which consent shall not be unreasonably withheld or delayed), retains its own counsel, of another firm of counsel for such affected Person)) that may be paid or incurred by any First Lien Secured Party in enforcing, or obtaining advice of counsel in respect of, any rights with respect to, or collecting, any or all of the First Lien Obligations and/or enforcing any rights with respect to, or collecting against, such Grantor under this Security Agreement.

(a) the Pledged Shares held by such Pledgor and the certificates, if any, representing such Pledged Shares and any interest of such Pledgor in the entries on the books of the issuer of the Pledged Shares or any financial intermediary pertaining to the Pledged Shares and all dividends, cash, warrants, rights, instruments and other property or Proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the Pledged Shares;

(b) the Pledged Debt and the instruments evidencing the Pledged Debt owed to such Pledgor, and all interest, cash, instruments and other property or Proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such Pledged Debt; and

(c) to the extent not covered by clauses (a) and (b) above, respectively, all Proceeds of any or all of the foregoing Collateral. For purposes of this Pledge Agreement, the term “Proceeds” includes whatever is receivable or received when Collateral or Proceeds are sold, exchanged, collected or otherwise disposed of, whether such disposition is voluntary or involuntary, and includes Proceeds of any indemnity or guarantee payable to any Pledgor or the Collateral Agent from time to time with respect to any of the Collateral;

Notwithstanding the foregoing, the Collateral for the Secured Obligations shall not include (i) any Excluded Stock and Stock Equivalents or any Excluded Property (as defined in the Security Agreement) and (ii) property or assets to the extent the grant of a Lien therein is prohibited by any contract, agreement, instrument or indenture governing such property or asset without the consent of any other party thereto (other than a Credit Party or a wholly owned subsidiary of a Credit Party) unless such consent has been expressly obtained, or would give any other party (other than a Credit Party or a wholly owned subsidiary of a Credit Party) to any such contract, agreement, instrument or indenture the right to terminate its obligations thereunder (other than to the extent that any such prohibition referred to in clause (ii) would be rendered ineffective pursuant to Sections 9-406, 9-407, 9-408 or 9-409 of the UCC (or any successor provision or provisions) of any relevant jurisdiction or any other applicable law) (it being understood that the foregoing shall not be deemed to obligate any Grantor to seek or obtain any such consents referred to in clause (ii) above).

(d) Notwithstanding anything to the contrary in this Section 2, at the Company’s option, the term Collateral, as it refers to the Collateral securing Additional First Lien

Obligations, shall not include any Stock and other securities of a Subsidiary to the extent that the pledge of such Stock and other securities would result in the Company being required to file separate financial statements of such Subsidiary with the SEC, but only to the extent necessary to not be subject to such requirement and only for so long as such requirement is in existence and only with respect to the relevant Additional First Lien Obligations affected; provided that neither US Holdings, the Company nor any Subsidiary shall take any action in the form of a reorganization, merger or other restructuring a principal purpose of which is to provide for the release of the Lien on any Stock pursuant to this clause (d). In addition, in the event that Rule 3-16 of Regulation S-X under the Securities Act of 1933, as amended (“Rule 3-16”) is amended, modified or interpreted by the SEC to require (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would require) the filing with the SEC (or any other Governmental Authority) of separate financial statements of any Subsidiary of the Company due to the fact that such Subsidiary’s Stock secures the Additional First Lien Obligations affected thereby, then the Stock of such Subsidiary will automatically be deemed not to be part of the Collateral securing the relevant Additional First Lien Obligations affected thereby but only to the extent necessary to not be subject to such requirement and only for so long as required to not be subject to such requirement. In such event, this Pledge Agreement may be amended or modified, without the consent of any First Lien Secured Party, to the extent necessary to release the Security Interests in favor of the Collateral Agent on the shares of Stock that are so deemed to no longer constitute part of the Collateral for the relevant Additional First Lien Obligations only. In the event that Rule 3-16 is amended, modified or interpreted by the SEC to permit (or is replaced with another rule or regulation, or any other law, rule or regulation is adopted, which would permit) such Subsidiary’s Stock to secure the Additional First Lien Obligations in excess of the amount then pledged without the filing with the SEC (or any other Governmental Authority) of separate financial statements of such Subsidiary, then the Stock of such Subsidiary will automatically be deemed to be a part of the Collateral for the relevant Additional First Lien Obligations. For the avoidance of doubt and notwithstanding anything to the contrary in this Agreement, nothing in this clause (d) shall limit the pledge of such Stock and other securities from securing the Obligations (as defined in the Credit Agreement) at all times or from securing any Additional First Lien Obligations that are not in respect of securities subject to regulation by the SEC.

(e) Notwithstanding anything to the contrary in this Section 2, at the Company’s option, the term Collateral, as it refers to the Collateral securing Additional First Lien Obligations, shall not include any property of US Holdings to the extent that the granting of a security interest in such property would result in a breach of any Contractual Requirement, or constitute a default under the terms of any material indenture (including a breach of the covenants contained in Section 4.12 of each of the indentures governing the terms of the Indebtedness of Energy Future Holdings Corp. (“EFH”) and the Company, and the terms of the Existing Notes Indentures), loan agreement, lease agreement, mortgage, deed of trust or other material agreement or instrument to which EFH or any of its Subsidiaries is a party or by which EFH or any of its Subsidiaries or any of their respective property or assets are bound, but only to the extent necessary to not be subject to such requirement and only for so long as such requirement is in existence and only with respect to the relevant Additional First Lien Obligations affected.

3. Security for the Obligations. This Pledge Agreement secures the payment of all the First Lien Obligations of each Credit Party. Without limiting the generality of the

foregoing, this Pledge Agreement secures the payment of all amounts that constitute part of the First Lien Obligations and would be owed by any of the Credit Parties to any of the First Lien Secured Parties under the Credit Documents, any Additional First Lien Agreement then in effect, Secured Cash Management Agreements, Secured Hedging Agreements and Secured Commodity Hedging Agreements but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving any Credit Party.

4. Delivery of the Collateral. All certificates or instruments, if any, representing or evidencing the Collateral shall be promptly delivered to and held by or on behalf of the Collateral Agent pursuant hereto to the extent required by the Credit Agreement or any Additional First Lien Agreement then in effect and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance reasonably satisfactory to the Collateral Agent. The Collateral Agent shall have the right, at any time after the occurrence and during the continuance of an Event of Default and with notice to the relevant Pledgor, to transfer to or to register in the name of the Collateral Agent or any of its nominees any or all of the Pledged Shares. Each delivery of Collateral (including any After-acquired Shares) shall be accompanied by a notice to the Collateral Agent describing the securities theretofore and then being pledged hereunder.

5. Representations and Warranties. Each Pledgor represents and warrants as follows:

(a) Schedule 1 hereto (i) correctly represents as of the Closing Date (A) the issuer, the certificate number, if any, the Pledgor and the record and beneficial owner, the number and class and the percentage of the issued and outstanding Equity Interests of such class of all Pledged Shares and (B) the issuer, the initial principal amount, the Pledgor and holder, date of issuance and maturity date of all Pledged Debt and (ii) together with the comparable schedule to each supplement hereto, includes all Equity Interests, debt securities and promissory notes required to be pledged hereunder. Except as set forth on Schedule 1 and except for Excluded Stock and Stock Equivalents, the Pledged Shares represent all of the issued and outstanding Equity Interests of each class of Equity Interests (or 65% of all of the issued and outstanding voting Equity Interests in the case of pledges of Equity Interests in Foreign Subsidiaries) in the issuer owned by a Pledgor on the Closing Date.

(b) Such Pledgor is the legal and beneficial owner of the Collateral pledged or assigned by such Pledgor hereunder free and clear of any Lien, except for the Liens created by this Pledge Agreement and Liens permitted under both (x) Sections 10.2(a), (g), (s) or (t) of or as “Permitted Liens” under the Credit Agreement and (y) under comparable provisions of each Additional First Lien Agreement.

(c) As of the Closing Date, the Pledged Shares pledged by such Pledgor hereunder on the Closing Date have been duly authorized and validly issued and, in the case of Pledged Shares issued by a corporation, are fully paid and non-assessable.

(d) The execution and delivery by such Pledgor of this Pledge Agreement and the pledge of the Collateral pledged by such Pledgor hereunder pursuant hereto create a legal, valid and enforceable security interest in such Collateral (in the case of the Stock of Foreign

Subsidiaries, to the extent the creation of such security interest in the Stock of Foreign Subsidiaries is governed by the UCC) and, (i) in the case of certificated securities, upon delivery of such certificated securities to the Collateral Agent in the State of New York, with necessary endorsements, and (ii) otherwise, upon the filing of a financing statement in the appropriate jurisdiction(s), shall constitute a fully perfected Lien on and security interest in the Collateral, securing the payment of the First Lien Obligations, in favor of the Collateral Agent for the benefit of the First Lien Secured Parties (in the case of the Stock of Foreign Subsidiaries, to the extent the creation and perfection of such security interest in the Stock of Foreign Subsidiaries is governed by the UCC), except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally and subject to general principles of equity.

(e) Such Pledgor has full power, authority and legal right to pledge all the Collateral pledged by such Pledgor pursuant to this Pledge Agreement and this Pledge Agreement constitutes a legal, valid and binding obligation of each Pledgor (in the case of the Stock of Foreign Subsidiaries, to the extent the creation and perfection of such security interest in the Stock of Foreign Subsidiaries is governed by the UCC), enforceable in accordance with its terms, except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally and subject to general principles of equity.

6. Certification of Limited Liability Company, Limited Partnership Interests and Pledged Debt.

(a) In the event that any Equity Interests in any Domestic Subsidiary that is organized as a limited liability company or limited partnership and pledged hereunder shall be represented by a certificate, the applicable Pledgor shall cause the issuer of such interests to elect to treat such interests as a “security” within the meaning of Article 8 of the Uniform Commercial Code of its jurisdiction of organization or formation, as applicable, by including in its organizational documents language substantially similar to the following and, accordingly, such interests shall be governed by Article 8 of the Uniform Commercial Code:

“The Partnership/Company hereby irrevocably elects that all membership interests in the Partnership/Company shall be securities governed by Article 8 of the Uniform Commercial Code of [jurisdiction of organization or formation, as applicable]. Each certificate evidencing partnership/membership interests in the Partnership/Company shall bear the following legend: “This certificate evidences an interest in [name of Partnership/LLC] and shall be a security for purposes of Article 8 of the Uniform Commercial Code.” No change to this provision shall be effective until all outstanding certificates have been surrendered for cancellation and any new certificates thereafter issued shall not bear the foregoing legend.”

(b) Each Pledgor will comply with Section 9.12 of the Credit Agreement and the equivalent provision of each Additional First Lien Agreement.

(c) In the event that any Equity Interests in any Foreign Subsidiary pledged hereunder are not represented by a certificate, the Pledgors agree not to permit such Foreign Subsidiary to issue Equity Interests represented by a certificate to any other Person, unless the Equity

Interests in such Foreign Subsidiary become represented by a certificate which is delivered to the Collateral Agent.

7. Further Assurances. Each Pledgor agrees that at any time and from time to time, at the expense of such Pledgor, it will execute or otherwise authorize the filing of any and all further documents, financing statements, agreements and instruments, and take all such further actions (including the filing and recording of financing statements, fixture filings, mortgages, deeds of trust and other documents), which may be required under any Applicable Law, or which the Collateral Agent, the Applicable First Lien Representative, the Required Secured Parties or the required lenders or debtholders under any Additional First Lien Agreement may reasonably request, in order (x) to perfect and protect any pledge, assignment or security interest granted or purported to be granted hereby (including the priority thereof) or (y) to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral.

(i) Each Pledgor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Collateral or any part thereof for any purpose not prohibited by the terms of this Pledge Agreement, the other Credit Documents or any Additional First Lien Agreement.

(ii) The Collateral Agent shall execute and deliver (or cause to be executed and delivered) to each Pledgor all such proxies and other instruments as such Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above.

(b) Subject to paragraph (c) below, each Pledgor shall be entitled to receive and retain and use, free and clear of the Lien created by this Pledge Agreement, any and all dividends, distributions, principal and interest made or paid in respect of the Collateral to the extent permitted by each of the Credit Agreement and each Additional First Lien Agreement, as applicable; provided, however, that any and all noncash dividends, interest, principal or other distributions that would constitute Pledged Shares or Pledged Debt, whether resulting from a subdivision, combination or reclassification of the outstanding Equity Interests of the issuer of any Pledged Shares or received in exchange for Pledged Shares or Pledged Debt or any part thereof, or in redemption thereof, or as a result of any merger, consolidation, acquisition or other exchange of assets to which such issuer may be a party or otherwise, shall be, and (as applicable) shall be forthwith delivered to the Collateral Agent to hold as, Collateral and shall, if received by such Pledgor, be received in trust for the benefit of the Collateral Agent, be segregated from the other property or funds of such Pledgor (as applicable) and be forthwith delivered to the Collateral Agent as Collateral in the same form as so received (with any necessary endorsement).

(c) Upon written notice to a Pledgor by the Collateral Agent following the occurrence and during the continuance of an Event of Default:

(i) all rights of such Pledgor to exercise or refrain from exercising the voting and other consensual rights that it would otherwise be entitled to exercise pursuant to Section 8(a)(i) shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights during the continuance of such Event of Default, provided that, unless otherwise directed by the Required Secured Parties, the Collateral Agent shall have the right from time to time following the occurrence and during the continuance of an Event of Default to permit the Pledgors to exercise such rights. After all Events of Default have been cured or waived, each Pledgor will have the right to exercise the voting and consensual rights that such Pledgor would otherwise be entitled to exercise pursuant to the terms of Section 8(a)(i) (and the obligations of the Collateral Agent under Section 8(a)(ii) shall be reinstated);

(ii) all rights of such Pledgor to receive the dividends, distributions and principal and interest payments that such Pledgor would otherwise be authorized to receive and retain pursuant to Section 8(b) shall cease, and all such rights shall thereupon become vested in the Collateral Agent, which shall thereupon have the sole right to receive and hold as Collateral such dividends, distributions and principal and interest payments during the continuance of such Event of Default. After all Events of Default have been cured or waived, the Collateral Agent shall repay to each Pledgor (without interest) and each Pledgor shall be entitled to receive, retain and use all dividends, distributions and principal and interest payments that such Pledgor would otherwise be permitted to receive, retain and use pursuant to the terms of Section 8(b);

(iii) all dividends, distributions and principal and interest payments that are received by such Pledgor contrary to the provisions of Section 8(b) shall be received in trust for the benefit of the Collateral Agent shall be segregated from other property or funds of such Pledgor and shall forthwith be delivered to the Collateral Agent as Collateral in the same form as so received (with any necessary endorsements); and

(iv) in order to permit the Collateral Agent to receive all dividends, distributions and principal and interest payments to which it may be entitled under Section 8(b) above, to exercise the voting and other consensual rights that it may be entitled to exercise pursuant to Section 8(c)(i) above, and to receive all dividends, distributions and principal and interest payments that it may be entitled to under Sections 8(c)(ii) and (c)(iii) above, such Pledgor shall, if necessary, upon written notice from the Collateral Agent, from time to time execute and deliver to the Collateral Agent, appropriate proxies, dividend payment orders and other instruments as the Collateral Agent may reasonably request.

(a) not (i) except as permitted by the Credit Agreement and each Additional First Lien Agreement, sell or otherwise dispose of, or grant any option or warrant with respect to, any of the Collateral or (ii) create or suffer to exist any consensual Lien upon or with respect to any of the Collateral, except for the Liens created by this Pledge Agreement and Liens permitted under both (x) under Sections 10.2(a), (g), (s) or (t) of or as “Permitted Liens” under the Credit Agreement and (y) under comparable provisions of each Additional First Lien Agreement; provided that in the event such Pledgor sells or otherwise disposes of assets as permitted by the Credit Agreement or any Additional First Lien Agreement, and such assets are or include any of the Collateral, the Collateral Agent shall release such Collateral to such Pledgor free and clear of the Lien created by this Pledge Agreement concurrently with the consummation of such sale;

(b) pledge and, if applicable, cause each Domestic Subsidiary to pledge, to the Collateral Agent for the benefit of the First Lien Secured Parties, immediately upon acquisition thereof, all the Equity Interests and all evidence of Indebtedness held or received by such Pledgor or Domestic Subsidiary required to be pledged hereunder pursuant to Section 9.12 of the Credit Agreement and/or the equivalent provision of each Additional First Lien Agreement, in each case pursuant to a supplement to this Pledge Agreement substantially in the form of Annex A hereto (it being understood that the execution and delivery of such a supplement shall not require the consent of any other Pledgor hereunder and that the rights and obligations of each Pledgor hereunder shall remain in full force and effect notwithstanding the addition of any new Subsidiary Pledgor as a party to this Pledge Agreement); and

(c) defend its and the Collateral Agent’s title or interest in and to all the Collateral (and in the Proceeds thereof) against any and all Liens (other than the Liens permitted under each of the Credit Agreement and each Additional First Lien Agreement and the Liens created by this Pledge Agreement), however arising, and any and all Persons whomsoever.

10. Collateral Agent Appointed Attorney-in-Fact. Each Pledgor hereby appoints, which appointment is irrevocable and coupled with an interest, the Collateral Agent as such Pledgor’s attorney-in-fact, with full authority in the place and stead of such Pledgor and in the name of such Pledgor or otherwise, to take any action and to execute any instrument, in each case after the occurrence and during the continuance of an Event of Default and with notice to such Pledgor, that the Collateral Agent may deem reasonably necessary or advisable to accomplish the purposes of this Pledge Agreement, including to receive, indorse and collect all instruments made payable to such Pledgor representing any dividend, distribution or principal or interest payment in respect of the Collateral or any part thereof and to give full discharge for the same.

11. The Collateral Agent’s Duties. The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Pledged Shares, whether or not the Collateral Agent or any other First Lien Secured Party has or is deemed to have

knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property.

(a) The Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also may with notice to the relevant Pledgor, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange broker’s board or at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, at such price or prices and upon such other terms as are commercially reasonable irrespective of the impact of any such sales on the market price of the Collateral. The Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers of Collateral to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and, upon consummation of any such sale, the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Collateral Agent or any First Lien Secured Party shall have the right upon any such public sale, and, to the extent permitted by law, upon any such private sale, to purchase all or any part of the Collateral so sold, and, subject to the terms of the Intercreditor Agreement, the Collateral Agent or such First Lien Secured Party may pay the purchase price by crediting the amount thereof against the First Lien Obligations. Each Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten days’ notice to such Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the extent permitted by law, each Pledgor hereby waives any claim against the Collateral Agent arising by reason of the fact that the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if the Collateral Agent accepts the first offer received and does not offer such Collateral to more than one offeree.

(b) The Collateral Agent shall apply the Proceeds of any collection or sale of the Collateral in the manner specified in Section 4.1 of the Intercreditor Agreement. Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the

purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

(d) All payments received by any Pledgor in respect of the Collateral after the occurrence and during the continuance of an Event of Default shall be received in trust for the benefit of the Collateral Agent shall be segregated from other property or funds of such Pledgor and shall be forthwith delivered to the Collateral Agent as Collateral in the same form as so received (with any necessary endorsement).

13. Amendments, etc. with Respect to the First Lien Obligations; Waiver of Rights. Each Pledgor shall remain obligated hereunder notwithstanding that, without any reservation of rights against any Pledgor and without notice to or further assent by any Pledgor, (a) any demand for payment of any of the First Lien Obligations made by the Collateral Agent or any other First Lien Secured Party may be rescinded by such party and any of the First Lien Obligations continued, (b) the First Lien Obligations, or the liability of any other party upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Collateral Agent or any other First Lien Secured Party, (c) the Credit Agreement, the other Credit Documents, the Letters of Credit, any Additional First Lien Agreement and any other documents executed and delivered in connection therewith, the Secured Cash Management Agreements, Secured Hedging Agreements and Secured Commodity Hedging Agreements and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders, as the case may be, or, in the case of any Secured Cash Management Agreement, Secured Hedging Agreement and Secured Commodity Hedging Agreement, the Cash Management Bank or Hedge Bank party thereto or in the case of any Additional First Lien Agreement, the trustee, agent or representative thereunder or the required lenders or holders thereunder) may deem advisable from time to time and (d) any collateral security, guarantee or right of offset at any time held by the Collateral Agent or any other First Lien Secured Party for the payment of the First Lien Obligations may be sold, exchanged, waived, surrendered or released. Neither the Collateral Agent nor any other First Lien Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the First Lien Obligations or for this Pledge Agreement or any property subject thereto. When making any demand hereunder against any Pledgor, the Collateral Agent or any other First Lien Secured Party may, but shall be under no obligation to, make a similar demand on the Company or any Pledgor or any other Person, and any failure by the Collateral Agent or any other First Lien Secured Party to make any such demand or to collect any payments from the Company or any Pledgor or any other Person or any release of the Company or any Pledgor or any other Person shall not relieve any Pledgor in respect of which a demand or collection is not made or any Pledgor not so released of its several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Collateral Agent or any other First Lien Secured Party against any Pledgor. For the purposes hereof “demand” shall include the commencement and continuance of any legal proceedings.

14. Continuing Security Interest; Assignments Under the Credit Agreement; Release.

(a) This Pledge Agreement shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon each Pledgor and the successors and assigns thereof, and shall inure to the benefit of the Collateral Agent and the other First Lien Secured Parties and their respective successors, endorsees, transferees and assigns until all Secured Obligations (other than any contingent indemnity obligations not then due) shall have been satisfied by payment in full, the Commitments shall be terminated and no Letters of Credit shall be outstanding (or all such Letters of Credit shall have been fully Cash Collateralized or otherwise back-stopped to the reasonable satisfaction of the applicable Letter of Credit Issuer), notwithstanding that from time to time during the term of the Credit Agreement, any Secured Cash Management Agreement, Secured Hedging Agreement, Secured Commodity Hedging Agreement and any Additional First Lien Agreements the Credit Parties may be free from any First Lien Obligations.

(b) Subject to the terms of the Intercreditor Agreement, a Pledgor shall automatically be released from its obligations hereunder and Security Interest in the Collateral of such Pledgor shall be automatically released (x) as it relates to the “Obligations” (as defined in the Credit Agreement), upon the consummation of any transaction permitted under the Credit Agreement, as a result of which such Pledgor ceases to be a Guarantor and (y) as it relates to the First Lien Obligations under any Additional First Lien Agreement, upon the consummation of any transaction permitted under such Additional First Lien Agreement, as a result of which such Pledgor ceases to be a guarantor under such Additional First Lien Agreement pursuant to the applicable provision(s) of such Additional First Lien Agreement.

(c) Subject to the terms of the Intercreditor Agreement, the Security Interest granted hereby in any Collateral shall be automatically released from the Liens of this Agreement (i) if (and to the extent) provided for in (A) Section 13.1 of the Credit Agreement and (B) any applicable provision of any Additional First Lien Agreement then in effect, (ii) upon the effectiveness of any written consent to the release of the security interest granted in such Collateral pursuant to Section 13.1 of the Credit Agreement and any applicable provision of any Additional First Lien Agreement then in effect and (iii) as otherwise may be provided in the Intercreditor Agreement. Any such release in connection with any sale, transfer or other disposition of such Collateral shall result in such Collateral being sold, transferred or disposed of, as applicable, free and clear of the Liens and Security Interest of this Pledge Agreement.

(d) In connection with any termination or release pursuant to the foregoing paragraph (a), (b) or (c), the Collateral Agent shall execute and deliver to any Pledgor or authorize the filing of, at such Pledgor’s expense, all documents that such Pledgor shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 14 shall be without recourse to or warranty by the Collateral Agent.

15. Reinstatement. Each Pledgor further agrees that, if any payment made by any Credit Party or other Person and applied to the First Lien Obligations is at any time annulled, avoided, set aside, rescinded, invalidated, declared to be fraudulent or preferential or otherwise required to be refunded or repaid, or the Proceeds of Collateral are required to be returned by any

First Lien Secured Party to such Credit Party, its estate, trustee, receiver or any other party, including any Pledgor, under any bankruptcy law, state, federal or foreign law, common law or equitable cause, then, to the extent of such payment or repayment, any Lien or other Collateral securing such liability shall be and remain in full force and effect, as fully as if such payment had never been made or, if prior thereto the Lien granted hereby or other Collateral securing such liability hereunder shall have been released or terminated by virtue of such cancellation or surrender), such Lien or other Collateral shall be reinstated in full force and effect, and such prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect any Lien or other Collateral securing the obligations of any Pledgor in respect of the amount of such payment.

16. Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 13.2 of the Credit Agreement (whether or not then in effect). All communications and notices hereunder to any Pledgor shall be given to it in care of the Company at the Company’s address set forth in Section 13.2 of the Credit Agreement (whether or not then in effect) and all notices to any holder of obligations under any Additional First Lien Agreements, at its address set forth in the Additional First Lien Secured Party Consent to the Security Agreement, as such address may be changed by written notice to the Collateral Agent and the Company.

17. Counterparts. This Pledge Agreement may be executed by one or more of the parties to this Pledge 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 Pledge Agreement signed by all the parties shall be lodged with the Collateral Agent and the Company.

18. Severability. Any provision of this Pledge 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. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

19. Integration. This Pledge Agreement together with the other Credit Documents and each Additional First Lien Agreement represents the agreement of each of the Pledgors with respect to the subject matter hereof and there are no promises, undertakings, representations or warranties by the Collateral Agent or any other First Lien Secured Party relative to the subject matter hereof not expressly set forth or referred to herein or in the other Credit Documents and each Additional First Lien Agreement.

(a) None of the terms or provisions of this Pledge Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the affected Pledgor and the Collateral Agent in accordance with Section 13.1 of the Credit Agreement

and by each other party to the extent required by (and in accordance with) the Intercreditor Agreement.

(b) Neither the Collateral Agent nor any First Lien Secured Party shall by any act (except by a written instrument pursuant to Section 20(a) hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent or any other First Lien Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent or any other First Lien Secured Party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy that the Collateral Agent or such other First Lien Secured Party would otherwise have on any future occasion.

(c) The rights, remedies, powers and privileges herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law.

21. Collateral Agent as Agent. Section 7 of the Security Agreement is incorporated herein, mutatis mutandis (to apply to this Agreement rather than to the Security Agreement).

22. Section Headings. The Section headings used in this Pledge Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

23. Successors and Assigns. This Pledge Agreement shall be binding upon the successors and assigns of each Pledgor and shall inure to the benefit of the Collateral Agent and the other First Lien Secured Parties and their respective successors and assigns, except that no Pledgor may assign, transfer or delegate any of its rights or obligations under this Pledge Agreement without the prior written consent of the Collateral Agent, except pursuant to transactions expressly permitted by the Credit Agreement.

24. WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS PLEDGE AGREEMENT, ANY OTHER CREDIT DOCUMENT, ANY ADDITIONAL FIRST LIEN AGREEMENT AND FOR ANY COUNTERCLAIM THEREIN.

(a) submits for itself and its property in any legal action or proceeding relating to this Pledge Agreement, the other Credit Documents and any Additional First Lien Agreement 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;

(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 referred to in Section 16 or at such other address of which the Collateral Agent shall have been notified pursuant thereto;

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section 25 any special, exemplary, punitive or consequential damages.

(a) it has been advised by counsel in the negotiation, execution and delivery of this Pledge Agreement and the other Credit Documents to which it is a party;

(b) neither the Collateral Agent nor any other Secured Party has any fiduciary relationship with or duty to any Pledgor arising out of or in connection with this Pledge Agreement or any of the other Credit Documents, and the relationship between the Pledgors, on the one hand, and the Collateral Agent and the other Secured Parties, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Credit Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders and any other Secured Party or among the Pledgors and the Lenders and any other Secured Party.

27. GOVERNING LAW. THIS PLEDGE 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.

upon the separateness of Oncor and its Subsidiaries (and in the case of the Oncor Credit Facility, Oncor Holdings and its Subsidiaries) from the Company and the Grantors, (iii) that Oncor Holdings and its Subsidiaries have assets and liabilities that are separate from those of Energy Future Holdings Corp. and its other Subsidiaries, (iv) that the First Lien Obligations owing under the Credit Documents and any Additional First Lien Agreement are obligations and liabilities of the Company and the Pledgors only, and are not the obligations or liabilities of Oncor Holdings or any of its Subsidiaries, (v) that the First Lien Secured Parties shall look solely to the Company, the Guarantors and their assets, and not to any assets, or to the pledge of any assets, owned by Oncor Holdings or any of its Subsidiaries, for the repayment of any amounts payable pursuant to the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement and for satisfaction of any other First Lien Obligations owing to the Secured Parties under the Credit Documents or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement, and (vi) that none of Oncor Holdings or its Subsidiaries shall be personally liable to the First Lien Secured Parties for any amounts payable, or any other liability, under the Credit Documents, any Additional First Lien Agreement or any Secured Cash Management Agreement, Secured Hedging Agreement or Secured Commodity Hedging Agreement.

(b) The Collateral Agent, on behalf of itself and the First Lien Secured Parties, shall not (i) initiate any legal proceeding to procure the appointment of an administrative receiver, or (ii) institute any bankruptcy, reorganization, insolvency, winding up, liquidation, or any like proceeding under applicable law, against Oncor Holdings, Oncor, or any of their Subsidiaries, or against any of Oncor Holdings, Oncor’s, or any of their Subsidiaries’ assets.

29. Intercreditor Agreement. Notwithstanding any provision to the contrary in this Pledge Agreement, this Pledge Agreement is subject to the provisions of the Intercreditor Agreement, which provisions shall supercede and control any conflicting provisions in this Pledge Agreement.

IN WITNESS WHEREOF, each of the undersigned has caused this Pledge Agreement to be duly executed and delivered by its duly authorized officer as of the day and year first above written.

A. Reference is made to the Credit Agreement, dated as of October 10, 2007 (as amended by Amendment No. 1 thereto dates as of August 7, 2009 and as the same may be further amended, restated, supplemented or otherwise modified, refinanced or replaced from time to time, the “Credit Agreement”) among US Holdings, the Company, the lending institutions from time to time parties thereto (the “Lenders”), Citibank, N.A., as Administrative Agent and as Collateral Agent and the other agents and entities party thereto, and the Guarantee dated as of October 10, 2007 (as the same may be amended, restated, supplemented or otherwise modified, refinanced or replaced from time to time, the “Guarantee”), among the Company, the Guarantors party thereto and the Collateral Agent.

C. The Pledgors have entered into the Pledge Agreement in order to induce the Administrative Agent, the Collateral Agent, the Lenders and the Letter of Credit Issuers to enter into Amendment No. 1 to the Credit Agreement and to induce the respective Lenders and the Letter of Credit Issuers to make their respective Extensions of Credit to the Company under the Credit Agreement and to induce one or more Cash Management Banks and/or Hedge Banks to enter into Secured Cash Management Agreements, Secured Hedging Agreements and Secured Commodity Hedging Agreements and to induce the holders of any Additional First Lien Obligations to make their respective Extensions of Credit thereunder.

D. The undersigned Guarantors (each an “Additional Pledgor”) are (a) the legal and beneficial owners of the Equity Interests described under Schedule 1 hereto and issued by the entities named therein (such pledged Equity Interests, together with any Equity Interests of the issuer of such Pledged Shares or any other Subsidiary held directly by any Additional Pledgor in the future (the “After-acquired Additional Pledged Shares”), and in each case to the extent such Equity Interests are not subject to the last sentence of Section 2 of the Pledge Agreement, referred to collectively herein as the “Additional Pledged Shares”) and (b) the legal and beneficial owners of the Indebtedness described under Schedule 1 hereto (together with any other Indebtedness owed to any Additional Pledgor hereafter and required to be pledged pursuant to Section 9.12 of the Credit Agreement and/or the equivalent provisions of any Additional First Lien Agreement, the “Additional Pledged Debt”).

E. Section 9.12 of the Credit Agreement and/or the equivalent provisions of any Additional First Lien Agreement and Section 9(b) of the Pledge Agreement provide that additional Subsidiaries may become Subsidiary Pledgors under the Pledge Agreement by execution and delivery of an instrument in the form of this Supplement. Each undersigned Additional Pledgor is executing this Supplement in accordance with the requirements of Section 9(b) of the Pledge Agreement to pledge to the Collateral Agent for the benefit of the First Lien Secured Parties the Additional Pledged Shares and the Additional Pledged Debt [and to become a Subsidiary Pledgor under the Pledge Agreement] in order to induce the Lenders and the Letter of Credit Issuers to make additional Extensions of Credit and as consideration for Extensions of Credit previously made and to induce the holders of any Additional First Lien Obligations to make their respective Extensions of Credit thereunder and as consideration for Extensions of Credit previously made and to induce one or more Cash Management Banks and/or Hedge Banks to enter into Secured Cash Management Agreements, Secured Hedging Agreements and Secured Commodity Hedging Agreements.

Accordingly, the Collateral Agent and each undersigned Additional Pledgor agree as follows:

SECTION 1. In accordance with Section 9(b) of the Pledge Agreement, each Additional Pledgor by its signature below hereby transfers, assigns and pledges to the Collateral Agent, for the benefit of the First Lien Secured Parties, and hereby grants to the Collateral Agent, for the benefit of the First Lien Secured Parties, a security interest in all of such Additional Pledgor’s right, title and interest in the following, whether now owned or existing or hereafter acquired or existing (collectively, the “Additional Collateral”):

(a) the Additional Pledged Shares held by such Additional Pledgor and the certificates representing such Additional Pledged Shares and any interest of such Additional Pledgor in the entries on the books of the issuer of the Additional Pledged Shares or any financial intermediary pertaining to the Additional Pledged Shares and all dividends, cash, warrants, rights, instruments and other property or Proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of the Additional Pledged Shares;

(b) the Additional Pledged Debt and the instruments evidencing the Additional Pledged Debt owed to such Additional Pledgor, and all interest, cash, instruments and other property or Proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such Additional Pledged Debt; and

(c) to the extent not covered by clauses (a) and (b) above, respectively, all Proceeds of any or all of the foregoing Additional Collateral. For purposes of this Supplement, the term “Proceeds” includes whatever is receivable or received when Additional Collateral or Proceeds are sold, exchanged, collected or otherwise disposed of, whether such disposition is voluntary or involuntary, and includes Proceeds of any indemnity or guarantee payable to any Additional Pledgor or the Collateral Agent from time to time with respect to any of the Additional Collateral.

For purposes of the Pledge Agreement, the Collateral shall be deemed to include the Additional Collateral.

[SECTION 2. Each Additional Pledgor by its signature below becomes a Pledgor under the Pledge Agreement with the same force and effect as if originally named therein as a Pledgor and each Additional Pledgor hereby agrees to all the terms and provisions of the Pledge Agreement applicable to it as a Pledgor thereunder. Each reference to a “Subsidiary Pledgor” or a “Pledgor” in the Pledge Agreement shall be deemed to include each Additional Pledgor. The Pledge Agreement is hereby incorporated herein by reference.]¹

(a) Schedule 1 hereto correctly represents as of the date hereof (A) the issuer, the certificate number, if any, the Additional Pledgor and record and beneficial owner, the number and class and the percentage of the issued and outstanding Equity Interests of such class of all Additional Pledged Shares and (B) the issuer, the initial principal amount, the Additional Pledgor and holder, date of issuance and maturity date of all Additional Pledged Debt. Except as set forth on Schedule 1 and except for Excluded Stock and Stock Equivalents, the Pledged Shares represent all of the issued and outstanding Equity Interests of each class of Equity Interests (or 65% of all of the issued and outstanding voting Equity Interests in the case of pledges of Equity Interests in Foreign Subsidiaries) in the issuer owned by a Pledgor on the Closing Date.

(b) Such Additional Pledgor is the legal and beneficial owner of the Additional Collateral pledged or assigned by such Additional Pledgor hereunder free and clear of any Lien, except for Permitted Liens and the Lien created by this Supplement to the Pledge Agreement.

(c) As of the date of this Supplement, the Additional Pledged Shares pledged by such Additional Pledgor hereunder have been duly authorized and validly issued and, in the case of Additional Pledged Shares issued by a corporation, are fully paid and non-assessable.

(d) The execution and delivery by such Additional Pledgor of this Supplement and the pledge of the Additional Collateral pledged by such Additional Pledgor hereunder pursuant hereto create a legal, valid and enforceable security interest in the Additional Collateral and, (i) in the case of certificated securities, upon delivery of such certificated securities to the Collateral Agent in the State of New York, with necessary endorsements, and (ii) otherwise, upon the filing of a financing statement in the appropriate jurisdiction(s), shall constitute a fully perfected lien and security interest in the Additional Collateral (in the case of the Stock of Foreign Subsidiaries, to the extent the creation of such security interest in the Stock of Foreign Subsidiaries is governed by the UCC), securing

the payment of the Obligations, in favor of the Collateral Agent for the benefit of the First Lien Secured Parties, except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally and subject to general principles of equity.

(e) Such Additional Pledgor has full power, authority and legal right to pledge all the Additional Collateral pledged by such Additional Pledgor pursuant to this Supplement, and this Supplement constitutes a legal, valid and binding obligation of each Additional Pledgor, enforceable in accordance with its terms, except as enforceability thereof may be limited by bankruptcy, insolvency or other similar laws affecting creditors’ rights generally and subject to general principles of equity.

SECTION [3][4].

		• Avoidance Issues: If any First Lien Party is required to disgorge or otherwise pay any amount to the estate of any Credit Party for any reason (a “*Recovery*”), then the First Lien Obligations shall be reinstated to the extent of such Recovery and the Discharge of the First Lien Obligations shall be deemed not to have occurred.

		• Separate Grants of Security and Classifications: The grants of Liens pursuant to the First Lien Documents and the Second Lien Credit Documents constitute two separate and distinct grants of Liens.

		• Post -Petition Interest: The Second Lien Parties shall not oppose or challenge any claim of the First Lien Parties for post-petition interest, fees or expenses.
