The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.14. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto, (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.17, or (e) the revocation of any notice of prepayment pursuant to Sections 2.07 and 2.09, then, in any such event, the Borrower shall compensate each applicable Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any applicable Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error.

The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

SECTION 2.15. Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) The Borrower shall indemnify the Administrative Agent and each Lender within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or by the Administrative Agent on its own behalf or on behalf of a Lender shall be conclusive absent manifest error.

(c) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d) Any Foreign Lender shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, or reasonably requested by the Borrower as will permit such payments to be made without withholding.

(e) In addition, the Borrower or the Administrative Agent shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

SECTION 2.16. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest or fees, or of amounts payable under Section 2.13, 2.14 or 2.15, or otherwise) prior to 1:00 p.m., New York City time, on the date when due, in immediately available funds, without set-off, counterclaim,

recoupment or deduction of any kind. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its at its address listed in Section 9.01(a) (or such other office as the Administrative Agent shall from time to time designate to the Borrower), except that payments pursuant to Sections 2.13, 2.14, 2.15 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder or under any other Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, such interest shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amount of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in

accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b) or 2.16(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.17. Mitigation Obligations; Replacement of Lenders.

(a) If (i) any Lender requests compensation under Section 2.13, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15 or (iii) any Lender becomes a Defaulting Lender, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If (i) any Lender requests compensation under Section 2.13, (ii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, (iii) any Lender becomes a Defaulting Lender, or (iv) any Lender has not consented to a proposed amendment, waiver or modification under this Agreement that requires the consent of all Lenders and which has been approved by Required Lenders, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.18. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then (until such time as the Administrative Agent and the Borrower have agreed that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender) the Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 9.02); provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender.

ARTICLE III
Representations and Warranties

The Borrower and each of its Consolidated Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite corporate, partnership, limited liability company or other applicable organizational power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business, in and is in good standing, in every jurisdiction where such qualification is required.

SECTION 3.02. Authorization; Enforceability. The Transactions are within the Borrower’s organizational powers and have been duly authorized by all necessary corporate and, if required, stockholder action. This Agreement has been duly executed and delivered by the Borrower and constitutes, the Mortgage Indenture constitutes, and each other Loan Document to which the Borrower is to be a party, when executed and delivered by the Borrower (and, in the case of the Collateral Mortgage Bonds, authenticated by the trustee therefor), will constitute, a legal, valid and binding obligation of the Borrower, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except for (i) such approvals of the ACC that have been obtained and are in full force and effect, and (ii) filings necessary to perfect Liens created under the Loan Documents (other than the Lien of the Mortgage Indenture, in respect of which all requisite filings have been made), (b) will not violate any Requirement of Law, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Borrower or any of its Consolidated Subsidiaries or its assets (including the Revolving Credit Agreement), or give rise to a right thereunder to require any payment to be made by the Borrower or any of its Consolidated Subsidiaries, and (d) will not result in the creation or imposition of any Lien on any asset of the Borrower or any of its Consolidated Subsidiaries, except Liens created under the Loan Documents or under the Mortgage Indenture.

SECTION 3.04. Financial Condition; No Material Adverse Change; Secured Indebtedness.

(a) The audited consolidated balance sheet and related statements of income, stockholders’ equity and cash flows of the Borrower and its Consolidated Subsidiaries for the fiscal year ended December 31, 2009 and the most recent financial statements delivered by the Borrower pursuant to Section 5.01(a) or (b), in each case, present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its Consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the case of the statements delivered pursuant to Section 5.01(a). Neither the Borrower nor any of its Consolidated Subsidiaries had, at the date of the most recent balance sheet referred to above, any Guarantee, contingent liability or liability for taxes, or any long-term lease or unusual forward or long-term commitment, including any interest rate or foreign currency swap or exchange transaction, which, in any case, is material to the Borrower and its Consolidated Subsidiaries, taken as a whole, and which is not reflected in the foregoing statements or in the notes thereto. During the period from December 31, 2009 to and including the Effective Date there has been no sale, transfer or other disposition by the Borrower or any of its Consolidated Subsidiaries of any part of its business or property, and no purchase or other acquisition of any business or property (including any Capital Stock of any other Person), which, in either case, is material in relation to the consolidated financial condition of the Borrower and its Consolidated Subsidiaries taken as a whole at December 31, 2009.

(b) Since December 31, 2009, there has been no material adverse change in the financial condition, results of operations, business or prospects of the Borrower and its Consolidated Subsidiaries, taken as a whole.

(b) Each of the Borrower and its Consolidated Subsidiaries owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Borrower and its Subsidiaries does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

SECTION 3.06. Litigation and Environmental Matters.

(a) Except as explicitly disclosed in the Disclosure Documents, there are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any of its Consolidated Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, would, individually or in the aggregate, result in a Material Adverse Effect or (ii) that involve any of the Loan Documents, the Mortgage Indenture or the Transactions.

(b) Except as explicitly disclosed in the Disclosure Documents, and except with respect to any other matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the Borrower nor any of its Consolidated Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability.

Except as explicitly disclosed in the Disclosure Documents, each of the Borrower and its Consolidated Subsidiaries is in compliance with all Requirements of Law, including the Fair Labor Standards Act, the Americans with Disabilities Act, the Foreign Corrupt Practices Act and Anti-Terrorism Laws, applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to be in compliance, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. No Default has occurred and is continuing.

SECTION 3.08. Federal Regulations. No part of the proceeds of any Loans will be used for “purchasing” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect or for any purpose that violates the provisions of the regulations of the Board. If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U-1 referred to in Regulation U.

SECTION 3.09. Investment Company Status.

(a) Neither the Borrower nor any of its Consolidated Subsidiaries is an “investment company” or a company “controlled” by an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

(b) The Borrower is not subject to regulation under any Requirement of Law (other than Regulation X of the Board and Requirements of Law pertaining to utility regulation) which limits its ability to incur Indebtedness.

SECTION 3.10. Taxes. Each of the Borrower and its Consolidated Subsidiaries has timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

SECTION 3.11. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of such Plan by an amount that has resulted or could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans by an amount that has resulted or could reasonably be expected to result in a Material Adverse Effect.

SECTION 3.12. Security Documents.

(a) (i) The Collateral Mortgage Bonds have been validly issued and authenticated and are entitled to the benefits of the Mortgage Indenture and secured by the Lien of the Mortgage Indenture. Upon delivery of the Collateral Mortgage Bonds to the Administrative Agent under a Bond Delivery Agreement and at all times thereafter, the Collateral Mortgage Bonds will be “Outstanding” and the Administrative Agent will be the “Holder” of the Collateral Mortgage Bonds for all purposes of the Mortgage Indenture. The Mortgage Indenture constitutes a valid mortgage lien on and a valid and perfected security interest in the properties or franchises described therein as being subject to the Lien of the Mortgage Indenture. As of the Effective Date no material properties or franchises subject to the Lien of the Mortgage Indenture have been released from such Lien, and, as of any subsequent date, no such properties or franchises shall have been released from the Lien of the Mortgage Indenture except in accordance with the terms thereof and hereof.

(ii) The Collateral Mortgage Bonds are not required to be registered under the Securities Act of 1933, as amended. The Mortgage Indenture conforms to the requirements of the Trust Indenture Act of 1939, as amended.

(b) The provisions of the Security Documents not covered by paragraph (a) above are effective to create, in favor of the Administrative Agent for the benefit of the secured parties thereunder, legal, valid and enforceable Liens on or in all of the Collateral subject thereto, and all necessary deliveries of property to the Administrative Agent and all necessary and appropriate recordings and filings have been made in all necessary and appropriate public offices so that the Liens created by such Security Documents constitute perfected Liens on or in all rights, titles, estates and interests of the Borrower and any applicable Subsidiaries in the Collateral covered thereby, prior and superior to all other Liens and all necessary and appropriate consents to the creation and perfection of such Liens have been obtained. No mortgage or financing statement or other instrument or recordation covering all or any part of the Collateral is on file in any recording office which has not been terminated or released, except as may have been filed in favor of the Administrative Agent.

SECTION 3.13. Disclosure. The Borrower has disclosed to the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. None of the reports, financial statements, certificates or other information furnished by or on behalf of the Borrower to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder (as modified or supplemented by, and taken together with, other information so furnished) contains any misstatement of a material fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to forward looking statements, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time and notes that there can be no assurance that such expectations, beliefs or projections will be achieved or accomplished and that such projections are subject to an increasing degree of uncertainty as they relate to later periods of time.

SECTION 3.14. Solvency. On the Effective Date, the Borrower is Solvent.

SECTION 3.15. Labor Matters. There are no strikes or other labor disputes against the Borrower or any of its Subsidiaries pending or, to the knowledge of the Borrower, threatened that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect. Hours worked by and payment made to employees of the Borrower and its Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable Requirement of Law dealing with such matters that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect. All payments due from the Borrower or any of its Subsidiaries on account of employee health and welfare insurance that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect if not paid have been paid or accrued as a liability on the books of the Borrower or the relevant Subsidiary.

(a) Neither the Borrower nor, to the knowledge of the Borrower, any of its Affiliates is in violation of any Requirement of Law relating to terrorism or money laundering (“Anti-Terrorism Laws”), including Executive Order No. 13224 on Terrorist Financing, effective September 24, 2001 (the “Executive Order”), and the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, Public Law 107-56.

Borrower accrued hereunder, shall become due and payable immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower, and (iii) deliver a notice of redemption under the Tenth Supplemental Indenture stating that such notice is being delivered pursuant to this Article VII; in case of any event with respect to the Borrower described in clause (h) or (i) of this Article, the Aggregate Commitments shall automatically terminate and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and other obligations of the Borrower accrued hereunder and the cash collateral referred to in clause (v) above, shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

ARTICLE VIII
The Administrative Agent

Each of the Lenders hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set

forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be any commercial bank organized under the laws of the United States of America or any State thereof having a combined capital and surplus and undivided profits of not less than $500,000,000, or an Affiliate of any such bank.

Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative 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 it was acting as Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or related agreement or any document furnished hereunder or thereunder.

Except with respect to the exercise of setoff rights of any Lender, in accordance with Section 9.08, the proceeds of which are applied in accordance with this Agreement, each Lender agrees that it will not take any action, nor institute any actions or proceedings, against the Borrower or with respect to any Loan Document, without the prior written consent of the Required Lenders or, as may be provided in this Agreement or the other Loan Documents, with the consent of the Administrative Agent.

The Lenders are not partners or co-venturers, and no Lender shall be liable for the acts or omissions of, or (except as otherwise set forth herein in case of the Administrative Agent) authorized to act for, any other Lender. The Administrative Agent shall have the exclusive right on behalf of the Lenders to enforce the payment of the principal of and interest on any Loan after the date such principal or interest has become due and payable pursuant to the terms of this Agreement.

The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

(c) Any party hereto may change its address or facsimile number for notices and other communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt.

SECTION 9.02. Waivers; Amendments.

(a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder or under any other Loan Document or the Mortgage Indenture shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Loan Documents and the Mortgage Indenture are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders or, in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Borrower, in each case with the consent of the Required Lenders or, in the case of the Tenth Supplemental Indenture or the Collateral Mortgage Bonds, in each case with the consent of the Required Lenders and as provided by the Mortgage Indenture with the Administrative Agent exercising the rights of the holder of the Collateral Mortgage Bonds and acting at the direction of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, or change the definition of “Applicable Margin”, in each case without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or

postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.16(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender, or (vi) release all or any portion of the Collateral Mortgage Bonds or release all or substantially all of any other Collateral from the Liens of the Security Documents without the consent of each Lender, in each case except for any such release expressly permitted hereunder or under any Security Document; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent. Notwithstanding the foregoing, any provision of this Agreement requiring the consent of a Lender unwilling to provide such consent may be amended by an agreement in writing entered into by the Borrower, the Required Lenders and the Administrative Agent if (1) by the terms of such agreement the Commitment of each such opposing Lender shall terminate upon the effectiveness of such amendment and (2) at the time such amendment becomes effective, each such opposing Lender receives payment in full of the principal of and interest accrued on each Loan made by it and all other amounts owing to it or accrued for its account under the Loan Documents.

SECTION 9.03. Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates (including due diligence expenses and the reasonable fees, charges and disbursements of counsel for the Administrative Agent) in connection with the arrangement and syndication of the credit facilities provided for herein, the preparation, execution, delivery and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated); (ii) all out-of-pocket expenses and charges of the Administrative Agent and its Affiliates in connection with any evaluations of Collateral conducted by it; and (iii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

(b) The Borrower shall indemnify the Administrative Agent and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any agreement or instrument contemplated hereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Transactions or any other transactions contemplated thereby, (ii) any Loan or the use of the proceeds therefrom,

(iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted primarily from the gross negligence or willful misconduct of such Indemnitee.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after delivery to the Borrower of a reasonably detailed statement therefor.

SECTION 9.04. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of any Lender, the Administrative Agent must give its prior written consent to such assignment (which consent shall not be unreasonably withheld), (ii) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of any Lender, the Borrower must give its prior written consent to such assignment (which consent

shall not be unreasonably withheld), (iii) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund of any Lender, or an assignment of the entire remaining amount of the assigning Lender’s Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall be in an aggregate amount of not less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, (iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default shall have occurred and be continuing Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section.

(c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in the City of New York a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(e) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce the Loan Documents and to approve any amendment, modification or waiver of any provision of the Loan Documents; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(c) as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.15(d) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. In the case of any Lender that is a fund that invests in bank loans, such Lender may, without the consent of the Borrower or the Administrative Agent, assign or pledge all or any portion of its rights under this Agreement, including the Loans and notes or any other instrument evidencing its rights as a Lender under this Agreement, to any holder of, trustee for, or any other representative of holders of, obligations owed or securities issued by, such fund, as security for such obligations or securities; provided that any foreclosure or similar action by such trustee or representative shall be subject to the provisions of this Section 9.04(b) concerning assignments.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms

hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC in connection with its activities as an SPC hereunder any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary in this Section 9.04, any SPC may (A) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrower and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis consistent with the provisions of Section 9.12 any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. The provisions of this Section relating any SPC may not be amended without the written consent of such SPC.

SECTION 9.05. Survival. All covenants, agreements, representations and warranties made by the Borrower in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid is outstanding and so long as any Commitment has not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans and the Aggregate Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic imaging shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.09. Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to any Loan Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement or any other Loan Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 9.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12. Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, auditors, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies under this Agreement or any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than the Borrower. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the Effective Date, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 9.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 9.14. Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any other party) hereby notifies the Borrower that, pursuant to the requirements of the USA Patriot Act, Title III of Pub. L. 107-56, signed into law October 26, 2001 (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act.

SCHEDULE 1.01

PRICING SCHEDULE

The “Applicable Margin” for any day are the respective annual percentage rates set forth below in the applicable row under the column corresponding to the Status that exists on such day:


	≥A-/A3			BBB+/Baa1			BBB/Baa2			≤BBB-/Baa3
Status	Xxxxx 0			Xxxxx 0			Xxxxx 0			Xxxxx 0
Xxxxxxxxxx Xxxxxx — Eurodollar Loans		1.75	%		2.00	%		2.25	%		2.75	%
Applicable Margin — ABR Loans		0.75	%		1.00	%		1.25	%		1.75	%

For purposes of this Pricing Schedule, the following terms have the following meanings:

“Level 1 Status” exists at any date if, at such date, the Index Debt is rated either A- or higher by S&P or A3 or higher by Xxxxx’x.

“Level 2 Status” exists at any date if, at such date, the Index Debt is rated either BBB+ or higher by S&P or Baa1 or higher by Xxxxx’x and (ii) Level 1 Status does not exist.

“Level 3 Status” exists at any date if, at such date (i) the Index Debt is rated either BBB or higher by S&P or Baa2 or higher by Xxxxx’x and (ii) neither Xxxxx 0 Xxxxxx xxx Xxxxx 0 Xxxxxx exists.

“Level 4 Status” exists at any date if, at such date, no other Status exists.

“Status” refers to the determination of which of Xxxxx 0 Xxxxxx, Xxxxx 0 Xxxxxx, Xxxxx 0 Xxxxxx or Level 4 Status, exists at any date.

Notwithstanding the foregoing, if the Index Debt is split-rated and the ratings differential is two or more ratings levels, the Status shall be determined assuming that (a) the higher rating is equal to the midpoint of the two ratings (e.g., for a split rating of BBB+/Baa3, BBB is the midpoint and will be deemed to be the higher rating, and for a split rating of BB/Baa1, Baa3 is the midpoint and will be deemed to be the higher rating) or (b) if there is no exact midpoint, the higher rating is equal to the higher of the two middle intermediate ratings (e.g., for a split rating of BBB+/Ba1, BBB is the higher of the two middle intermediate ratings and will be deemed to be the higher rating, and for a split rating of BB/Baa2, Baa3 is the higher of the two middle intermediate ratings and will be deemed to be the higher rating).

If at any time the Index Debt is unrated by Xxxxx’x or S&P, Level 4 Status shall exist; provided that if the reason that there is no such Xxxxx’x rating or S&P rating results from Xxxxx’x or S&P, as the case may be, ceasing to issue debt ratings generally, then the Borrower and the Administrative Agent may select another nationally-recognized rating agency to substitute for Xxxxx’x or S&P, as applicable, for purposes of the foregoing Schedule (and all references herein to Xxxxx’x or S&P, as applicable, shall refer to such substitute rating agency), and until a substitute nationally-recognized rating agency is so selected the Status shall be determined by reference to the rating most recently in effect prior to such cessation.

The Applicable Margin shall be increased or decreased in accordance with the foregoing Schedule upon any change in the applicable ratings of the Index Debt. The ratings of the Index Debt in effect at any date are those in effect at the close of business on such date.
