Section 2 - Financial Information

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On June 8, 2023, Avista Corporation (Avista Corp. or the Company) amended its committed line of credit facility, increasing the aggregate amount available from $400 million to $500 million.

The amendment also extended the expiration date to June 8, 2028, and provides for two possible additional extensions of one year each. The amendment also replaced the London interbank offered rate (LIBOR) provisions with Secured Overnight Financing Rate (SOFR) provisions.

The Company's obligations under the committed line of credit agreement are secured by $500 million in principal amount of non-transferable first mortgage bonds of the Company, bearing interest at a nominal rate of 12 percent, issued to the agent bank. Principal and interest in these bonds would become due and payable only in the event, and then only to the extent, that the Company defaults on its obligations under the committed line of credit.

The amendment to the committed line of credit facility did not change the covenants in the agreement, which include the covenant not to permit the ratio of “consolidated total debt” to “consolidated total capitalization” of Avista Corp. to be greater than 65 percent at any time, or the events of default, which include a change in control (as defined in the agreement) and a cross-default from other indebtedness, all of which are customary.

On June 8, 2023, the Company also terminated the $100 million line of credit that was originally to expire on November 30, 2023.

This bond is one of the bonds, of the series herein designated, described or provided for in the within-mentioned Mortgage.

CITIBANK, N.A.

Trustee


By
	Authorized Signatory

The principal of and premium, if any, and interest on this bond payable at Maturity shall be payable upon presentation hereof at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts. The interest on this bond (other than interest payable at Maturity) shall be paid directly to the registered owner hereof. As used herein, the term "Maturity" shall mean the date on which the principal of this bond becomes due and payable, whether at stated maturity, upon redemption or acceleration, or otherwise.

This bond is one of an issue of bonds of the Company issuable in series and is one of a series known as its First Mortgage Bonds , Collateral Series 2023A, all bonds of all such series being issued and issuable under and equally secured (except insofar as any sinking or other fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust, dated as of June 1, 1939 (the "Original Mortgage"), executed by the Company (formerly known as The Washington Water Power Company) to City Bank Farmers Trust Company and Ralph E. Morton, as Trustees (Citibank, N.A., successor Trustee to both said Trustees). The Original Mortgage has been amended and supplemented by various supplemental indentures, including the Sixty-eighth Supplemental Indenture, dated as of June 1, 2023 (the "Sixty-eighth Supplemental Indenture"), and, as so amended and supplemented, is herein called the "Mortgage." Reference is made to the Mortgage for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustee in respect thereof, the duties and immunities of the Trustee, the te1ms and conditions upon which the bonds are and are to be secured and the circumstances under which additional bonds may be issued. If there shall be a conflict between the terms of this bond and the provisions of the Mortgage, the provisions of the Mortgage shall control to the extent permitted by law. The holder of this bond, by its acceptance hereof, shall be deemed to have consented and agreed to all of the terms and provisions of the Mortgage.

The Mortgage may be modified or altered by affirmative vote of the holders of at least 60% in principal amount of the bonds outstanding under the Mortgage, considered as one class, or, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected, then such modification or alteration may be effected with the affirmative vote only of 60% in principal amount of the bonds outstanding of the series so to be affected, considered as one class, and, furthermore, for limited purposes, the Mortgage may be modified or altered without any consent or other action of holders of any series of bonds. No modification or alteration shall, however, permit an extension of the Maturity of the principal of, or interest on, this bond or a reduction in such principal or the rate of interest hereon or any other modification in the terms of payment of such principal or interest or the creation of any lien equal or prior to the lien of the Mortgage or deprive the holder of a lien on the mortgaged and pledged property without the consent of the holder hereof.

The bonds of this series are not redeemable, in whole or in part, at the option of

the Company.

The bonds of this series have been issued and delivered to MUFG Bank, Ltd. (as successor by appointment to MUFG Union Bank, N.A.), as Administrative Agent under the Credit Agreement (as such terms are defined in the Sixty-eighth Supplemental Indenture) in order to provide the benefit of the lien of the Mortgage as security for the obligation of the Company under the Credit Agreement to pay the Obligations (as so defined), to the extent and subject to the limitations set forth below. Subject to the terms and conditions specified in the Sixty-eighth Supplemental Indenture,

the Stated Maturity Date shall be automatically extended upon the extension of the Expiration Date (as such term is defined in the Sixty-eighth Supplemental Indenture) pursuant to any provision of the Credit Agreement, but in no event beyond December 31, 2050.

Upon the earliest of (A) the occurrence of an Event of Default (as defined in the Sixty-eighth Supplemental Indenture) under the Credit Agreement, other than an Event of Default referred to in clause (B) below, and further upon the condition that, in accordance with the terms of the Credit Agreement, (1) the Commitments (as so defined) shall have been or shall have terminated and any Loans (as so defined) shall have been declared to be or shall have otherwise become due and payable immediately, (2) the Administrative Agent shall have demanded that the Company provide cash collateral in the amount of the total LC Exposure (as so defined), if any, and (3) the Administrative Agent shall have delivered to the Company a notice demanding redemption of the bonds of this series which notice states that it is being delivered pursuant to Article VII of the Credit Agreement, (B) the occurrence of an Event of Default under paragraph (g) or (h) of Article VII of the Credit Agreement, and (C) the Stated Maturity Date, then all bonds of this series shall be redeemed or paid immediately at the principal amount thereof plus accrued interest to the date of redemption or payment.

The obligation of the Company to pay the accrued interest on bonds of this series on any Interest Payment Date prior to Maturity (a) shall be deemed to have been satisfied and discharged in full in the event that all amounts then due in respect of the Obligations shall have been paid or (b) shall be deemed to remain unsatisfied in an amount equal to the aggregate amount then due in respect of the Obligations and remaining unpaid (not in excess, however, of the amount otherwise then due in respect of interest on the bonds of this series).

The obligation of the Company to pay the principal of and accrued interest on bonds of this series at or after Maturity (x) shall be deemed to have been satisfied and discharged in full in the event that (1) all amounts then due in respect of the Obligations shall have been paid and (2) no Letter of Credit (as defined in the Sixty-eighth Supplemental Indenture) shall remain outstanding (or all outstanding Letters of Credit shall have been cash collateralized in full pursuant to the terms of the Credit Agreement) or (y) shall be deemed to remain unsatisfied in an amount equal to the sum of (1) the aggregate amount then due in respect of the Obligations and remaining unpaid plus (2) the aggregate stated amount of all outstanding Letters of Credit to the extent that such Letters of Credit have not been cash collateralized pursuant to the terms of the Credit Agreement (not in excess, however, of the amount otherwise then due in respect of principal of and accrued interest on the bonds of this series).

Anything in this bond to the contrary notwithstanding, if, at the time of the Maturity of the bonds of this series, the stated aggregate principal amount of such bonds then outstanding shall exceed the aggregate amount of the Commitments (provided that the aggregate amount of the Commitments shall be determined without regard to any termination of the Commitments at such time or pursuant to Section 2.10(a) or Article VII of the Credit Agreement), the aggregate principal amount of such bonds shall be deemed to have been reduced by the amount of such excess.

The principal hereof, together with all accrued and unpaid interest hereon, may be declared or may become due prior to the Stated Maturity Date on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a Completed Default as in the Mortgage provided.

As provided in the Mortgage and subject to certain limitations therein set forth, this bond or any portion of the principal amount hereof will be deemed to have been paid if there has been irrevocably deposited with the Trustee moneys or direct obligations of or obligations guaranteed by the United States of America, the principal of and interest on which when due, and without regard to any reinvestment thereof, will provide moneys which, together with moneys so deposited, will be sufficient

to pay when due the principal of and premium, if any, and interest on this bond when due.

The Mortgage contains terms, provisions and conditions relating to the consolidation or merger of the Company with or into, and the conveyance or other transfer, or lease, of assets to, another corporation and to the assumption by such other corporation, in certain circumstances, of all of the obligations of the Company under the Mortgage and on the bonds secured thereby.

This bond is non-transferable except as required to effect transfer to any successor administrative agent under the Credit Agreement, any such transfer to be made at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, together with a written instrument of transfer whenever required by the Company duly executed by the registered owner or by its duly authorized attorney, and, thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes.

In the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.

No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.

This bond shall not become obligatory until Citibank, N.A., the Trustee under the Mortgage, or its successor thereunder, shall have signed the form of certificate endorsed hereon.

In addition, on the Effective Date, each Increasing Lender shall be deemed to have purchased by assignment from the other Lenders (and such other Lenders shall be deemed to have assigned to the Increasing Lenders) a portion of the participations (if any) then held by such other Lenders in the outstanding LC Exposure, to the extent required so that, after giving effect to all such deemed purchases and assignments, each Lender’s LC Exposure shall equal such Lender’s Pro Rata Share (as determined after giving effect to this Amendment) of the aggregate LC Exposure at such time.

(b) Except as specifically contemplated by this Amendment, the Existing Credit Agreement and the other Loan Documents shall remain in full force and effect and are hereby ratified and confirmed. Without limiting the generality of the foregoing, the First Mortgage, as modified by the New Supplemental Indenture, and all of the collateral described therein do and shall continue to secure the payment of all obligations under the New First Mortgage Bond.

(c) The execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or remedy of the Administrative Agent, any Issuing Bank or any Lender under any of the Loan Documents or constitute a waiver of any provision of any of the Loan Documents, except as expressly provided herein.

SECTION 6. Execution in Counterparts; Electronic Execution. This Amendment may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Amendment by facsimile or other electronic transmission shall be effective as an original executed counterpart and shall be deemed a representation that the original executed counterpart will be delivered. The words “execution,” “executed,” “signed,” “signature,” “delivery,” and words of like import in or relating to any document to be signed in connection with this Amendment and the transactions contemplated hereby shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; provided, that nothing herein shall require the Administrative Agent to accept electronic signatures in any form or format without its prior written consent; provided, further, that, without limiting the foregoing, upon the request of the Administrative Agent, any electronic signature shall be promptly followed by such manually executed counterpart.

SECTION 7. Governing Law. THIS AMENDMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

SECTION 8. Headings. Section headings in this Amendment are for convenience of reference only and shall not constitute a part of this Amendment for any other purpose.

SECTION 9. Waiver of Jury Trial

- 7 -

. Each party hereto hereby waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any litigation directly or indirectly arising out of, under or in connection with this AMenDMENT, THE EXISTING CREDIT AGREEMENT, AS AMENDED BY THIS AMENDMENT, or any of the other Loan Documents. 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 AMENDMENT and the other Loan Documents, as applicable, by, among other things, the mutual waivers and certifications in this Section 9.

SECTION 10. Miscellaneous. This Amendment shall be subject to the provisions of Sections 10.12 and 10.15 of the Existing Credit Agreement, each of which is incorporated by reference herein, mutatis mutandis.

SECTION 11. Eurodollar Rate Provisions. The amendments to LIBOR Related Definitions (as defined below) and provisions with respect thereto set forth in the pages of the Amended Credit Agreement attached as Exhibit A hereto shall not apply with respect to (a) any Loan requested, made or outstanding that bears interest at a rate determined by reference to the Eurodollar Rate (a “LIBOR Loan”) that (i) is or was set prior to the Effective Date and (ii) is held constant for a specifically designated period and is not reset on a daily or substantially daily basis (disregarding day count, weekend or holiday conventions) and (b) any retroactive margin, yield, fee or commission increases available to the Administrative Agent or the Lenders as a result of any inaccuracy in any financial statement or compliance certificate that, if corrected, would have led to the application of a higher interest margin or yield with respect to any Loan or any higher fee or commission for any applicable period, and in each case, the LIBOR Related Definitions and provisions with respect thereto (as in effect immediately prior to giving effect to the provisions of this Amendment) shall continue in effect solely for such purpose; provided that, with respect to any such LIBOR Loan described in subclause (a) of this Section 11, such LIBOR Loan shall only continue in effect in accordance with its terms until the then-current Interest Period (as defined in the Existing Credit Agreement) for such LIBOR Loan has concluded. As used in this Section 11, “LIBOR Related Definitions” means any term defined in the Existing Credit Agreement or any other Loan Document (or any partial definition thereof) as in effect immediately prior to giving effect to the provisions of this Amendment on the Effective Date, however phrased, primarily relating to the determination, administration or calculation of the Eurodollar Rate, including by way of example any instances of “Eurodollar” or “Eurodollar Rate”.

For all purposes under the Loan Documents, in connection with any division or plan of division under Delaware law (or any comparable event under a different jurisdiction’s laws): (a) if any asset, right, obligation or liability of any person becomes the asset, right, obligation or liability of a different person, then it shall be deemed to have been transferred from the original person to the subsequent person, and (b) if any new person comes into existence, such new person shall be deemed to have been organized on the first date of its existence by the holders of its Equity Interests at such time.

Section 1.04 Rates. The Administrative Agent does not warrant or accept responsibility for, and shall not have any liability with respect to, (a) the continuation of, administration of, submission of, calculation of or any other matter related to the Alternate Base Rate, the Term SOFR Reference Rate, Adjusted Term SOFR or Term SOFR, or any component definition thereof or rates referred to in the definition thereof, or any alternative, successor or replacement rate thereto (including any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement rate (including any Benchmark Replacement) will be similar to, or produce the same value or economic equivalence of, or have the same volume or liquidity as, the Alternate Base Rate, the Term SOFR Reference Rate, Adjusted Term SOFR, Term SOFR or any other Benchmark prior to its discontinuance or unavailability, or (b) the effect, implementation or composition of any Conforming Changes. The Administrative Agent and its affiliates or other related entities may engage in transactions that affect the calculation of the Alternate Base Rate, the Term SOFR Reference Rate, Adjusted Term SOFR, Term SOFR, any alternative, successor or replacement rate (including any Benchmark Replacement) or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower. The Administrative Agent may select information sources or services in its reasonable discretion to ascertain the Alternate Base Rate, the Term SOFR Reference Rate, Adjusted Term SOFR, Term SOFR or any other Benchmark, or any component definition thereof or rates referred to in the definition thereof, in each case pursuant to the terms of this Agreement, and shall have no liability to the Borrower, any Lender, any Issuing Bank or any other person for damages of any kind, including direct or indirect, special, punitive, incidental or consequential damages, costs,

losses or expenses (whetherin tort, contractor otherwise and whether at law or in equity), for any error or calculation of any such rate (or component thereof) provided by any such information source or service.

ARTICLE II

THE CREDITS

Section 2.01 Commitments. Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Lender agrees, severally and not jointly, to make Loans to the Borrower, at any time and from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not result in (a) the Revolving Credit Exposure of any Lender exceeding such Lender’s Commitment or (b) the total Revolving Credit Exposures exceeding the total Commitments. Within the limits set forth in the preceding sentence, the Borrower may borrow, pay or prepay, and reborrow Loans during the Availability Period, subject to the terms, conditions and limitations set forth herein.

Section 2.02 Loans.

(a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their Commitments. The failure of any Lender to make any Loan required to be made hereunder shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however, that no Lender shall be responsible for the failure of any other Lender to make any Loan required to be made by such other Lender). The Loans comprising each Borrowing shall be in the aggregate principal amount of $1,000,000 or a whole-integer multiple of $100,000 in excess thereof.

(b) Subject to Section 2.09, each Borrowing shall be comprised entirely of ABR Loans or SOFR Loans, as the Borrower may request pursuant to Section 2.03. Each Lender may at its option fulfill its Commitment with respect to any SOFR Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement or any applicable Note. Borrowings of more than one Type may be outstanding at the same time; provided, however, that the Borrower shall not be entitled to request any Borrowing which, if made, would result in an aggregate of more than fifteen separate SOFR Loans of any Lender being outstanding hereunder at any one time. For purposes of the foregoing, Loans having different Interest Periods, regardless of whether they commence on the same date, shall be considered separate Loans.

(c) Subject to paragraph (e) below, each Lender shall make a Loan in the amount of its Pro Rata Share of each Borrowing on the proposed date thereof by wire transfer of immediately available funds to the Administrative Agent in Los Angeles, California, not later than 2:00 p.m., New York, New York time, and the Administrative Agent shall by 4:00 p.m., New York, New York time, make available to the Borrower in immediately available funds the amounts so

received (i) by wire transfer for credit to the account of the Borrower with Wells Fargo Bank bearingAccount Number 4168814770, ABA # 121000248, re: Avista Corp. or (ii) as otherwise specified by the Borrower in its notice of Borrowing or, if a Borrowing shall not occur on such date because any condition precedent herein specified shall not have been met, return the amounts so received to the respective Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the date of any SOFR Borrowing or prior to 2:00 p.m., New York, New York time, on the date of any ABR Borrowing that such Lender will not make available to the Administrative Agent such Lender’s portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with this paragraph (c), and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have made such portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Effective Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement.

(d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request any Borrowing if the Interest Period requested with respect thereto would end after the Expiration Date.

(e) The Borrower may refinance all or any part of any Borrowing with a new Borrowing of the same or a different Type, subject to the conditions and limitations set forth in this Agreement. Any Borrowing or part thereof so refinanced shall be deemed to be repaid or prepaid in accordance with Section 2.04 or 2.11, as applicable, with the proceeds of the new Borrowing, and the proceeds of the new Borrowing, to the extent they do not exceed the principal amount of the Borrowing being refinanced, shall not be paid by the Lenders to the Administrative Agent or by the Administrative Agent to the Borrower pursuant to paragraph (c) above.

Section 2.03 Notice of Borrowings. To request a Borrowing, the Borrower shall give the Administrative Agent notice thereof (a) in the case of a SOFR Borrowing, not later than 12:00 noon, New York, New York time, three (3) U.S. Government Securities Business Days before a proposed borrowing and (b) in the case of an ABR Borrowing, not later than 12:00 noon, New York, New York time, the day of a proposed borrowing. Such notice shall be irrevocable and shall in each case refer to this Agreement and specify (i) whether the Borrowing then being requested is to be a SOFR Borrowing or an ABR Borrowing; (ii) the date of such Borrowing (which shall be

a Business Day) and the amount thereof; and (iii) if such Borrowing is to be a SOFR Borrowing, the Interest Period with respect thereto. If no election as to the Type of Borrowing is specified in any such notice, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period with respect to any SOFR Borrowing is specified in any such notice, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. If the Borrower shall not have given notice in accordance with this Section 2.03 of its election to refinance a Borrowing or given notice to the Administrative Agent not later than 12:00 noon, New York, New York time, on the last day of the Interest Period applicable to such Borrowing that it will not refinance such Borrowing, then the Borrower shall be deemed to have given notice of an election to refinance such Borrowing with an ABR Borrowing. The Administrative Agent shall promptly advise the Lenders of any notice given pursuant to this Section 2.03 and of each Lender’s portion of the requested Borrowing.

Section 2.04 Repayment of Loans; Evidence of Debt.

The Borrower hereby unconditionally promises to pay each Lender the then unpaid principal amount of each Loan of such Lender on the last day of the Interest Period applicable to such Loan and on the Expiration Date. Each Loan shall bear interest on the outstanding principal balance thereof as set forth in Section 2.07.

Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

The Administrative Agent shall maintain accounts in which it shall record

(i) the amount and date of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal, interest or fees due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any principal, interest or fees received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

Any Lender may request that Loans made by it be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns). Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be represented by one or more Notes in such form payable to the

order of the payee named therein (or, if such Note is a registered Note, to such payee and its registered assigns).

Section 2.05 Letters of Credit.

Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own account, in a form reasonably acceptable to the Administrative Agent and the applicable Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control; provided, however, that any letter agreement entered into by the Borrower with an Issuing Bank from time to time with respect to the maximum Issuing Bank Exposure of such Issuing Bank shall control with respect thereto.

To request the issuance of a Letter of Credit (or the renewal, extension or other amendment of an outstanding Letter of Credit), the Borrower shall hand-deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the applicable Issuing Bank) to the applicable Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, renewal, extension or other amendment) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be renewed, extended or otherwise amended, and specifying the date of issuance, renewal, extension or other amendment (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, renew, extend or otherwise amend such Letter of Credit. If requested by such Issuing Bank, the Borrower shall also submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, renewed, extended or otherwise amended only if (and upon the issuance, renewal, extension or other amendment of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, renewal, extension or other amendment, (i) the total LC Exposure would not exceed $200,000,000 and (ii) the total Revolving Credit Exposures would not exceed the total Commitments.

Each Letter of Credit shall expire (or, in the case of an Evergreen Letter of Credit, shall expire if the applicable Issuing Bank gives the required notice of nonrenewal or nonextension) not later than the close of business on the date that is five Business Days prior to the first anniversary of the Expiration Date. Each Issuing Bank agrees to notify the Borrower, substantially simultaneously with its notice to the beneficiary of an Evergreen Letter of Credit, if such Issuing Bank decides not to renew or extend such Evergreen Letter of Credit; provided, however, that such Issuing Bank’s failure to so notify the Borrower shall not affect the nonrenewal or nonextension of such Evergreen Letter of Credit.

By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the applicable Issuing Bank or any Lender, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of such Issuing Bank, such Lender’s Pro Rata Share of (i) each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section and (ii) any reimbursement payment required to be refunded to the Borrower for any reason, to the extent received by such Lender. Each Lender acknowledges and agrees that its obligation to acquire participations in respect of Letters of Credit pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any renewal, extension or other amendment of any Letter of Credit or the occurrence and continuance of a Default or Event of Default or a reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

If the Issuing Bank of a Letter of Credit shall make an LC Disbursement in respect of such Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 3:00 p.m., New York, New York time, on (i) the Business Day on which the Borrower receives notice of such LC Disbursement, if such notice is received prior to 1:00 p.m., New York, New York time, on the day of receipt, or (ii) the Business Day immediately following the day on which the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided,however, that, if such LC Disbursement is in the amount of $1,000,000 or more, the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Pro Rata Share thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Pro Rata Share of the payment then due from the Borrower, in the same manner as provided in Section 2.02 with respect to Loans made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to such Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the relevant Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Issuing Bank, to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank of a Letter of Credit for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall

not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect, or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent nor any Lender or Issuing Bank, nor any of their respective directors, officers, employees or agents, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit, any payment or failure to make payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of any technicalterm or any consequence arisingfrom any cause beyond the control of the applicable Issuing Bank; provided, however, that the foregoing shall not excuse the Issuing Bank of a Letter of Credit from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by such Issuing Bank’s gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and nonappealable judgment). The parties hereto agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank of a Letter of Credit (as determined by a court of competent jurisdiction in a final and nonappealable judgment), such Issuing Bank shall be deemed to have exercised reasonable care in each action taken or not taken thereby in respect of such Letter of Credit. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to each document presented that appears on its face to be in substantial compliance with the terms of a Letter of Credit, the applicable Issuing Bank may, in its sole discretion, either accept and make payment upon such document without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such document if such document is not in strict compliance with the terms of such Letter of Credit.

The Issuing Bank of a Letter of Credit shall, promptly following its receipt of documents purporting to represent a demand for payment under such Letter of Credit, examine all such documents. Such Issuing Bank shall promptly notify the

Administrative Agent and the Borrower by telephone (confirmed by telecopier) of such demand for payment and whether such Issuing Bank has made or will make an LC Disbursement in respect thereof; provided,however, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

If the Issuing Bank of a Letter of Credit shall make an LC Disbursement under such Letter of Credit, then, unless the Borrower shall reimburse such LC Disbursement in full on the date on which such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date on which such LC Disbursement is made to but excluding the date on which the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided,however, that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.08 shall apply. Interest accrued pursuant to this paragraph shall be for the account of such Issuing Bank, except that interest accrued on or after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

If any Event of Default shall occur and be continuing, then, on the Business Day on which the Borrower receives notice from the Administrative Agent, at the request of any Issuing Bank of an outstanding Letter of Credit or the Required Lenders, demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit into an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Issuing Banks and the Lenders, an amount in cash equal to the total LC Exposure as of such date plus any accrued and unpaid interest thereon; provided, however, that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (g) or (h) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under the Loan Documents, pursuant to documentation executed by the Borrower in form and substance reasonably satisfactory to the Administrative Agent. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Such deposits may, at the option and sole discretion of the Administrative Agent, be invested in one or more money-market accounts, but such deposits shall not otherwise be invested or bear interest. Interest or other profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Banks for LC Disbursements for which they have not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the total LC Exposure at such time or be applied to satisfy other obligations of the Borrower under the Loan Documents. If the Borrower is required to provide cash collateral hereunder as a result of the occurrence of an Event of Default, the full amount of such cash collateral (to the extent not applied as aforesaid) shall be

returned to the Borrower within three Business Days after all Events of Default have been cured or waived. The Borrower hereby grants to the Administrative Agent a security interest in all such accounts in the name of the Administrative Agent and the cash collateral and investments held therein or pursuant thereto from time to time, including any interest or other profits on any such investments, to secure the obligations of the Borrower to the Administrative Agent, the Issuing Banks and the Lenders under this Agreement and the other Loan Documents.

In the event that any Letter of Credit remains outstanding on the Expiration Date and has an expiration date thereafter, the Borrower shall either (i) deposit into an account with the Administrative Agent an amount in cash equal to the total LC Exposure as of such date with respect to such Letter of Credit, to be held and applied as provided in Section 2.05(i), or (ii) enter into an agreement with the Issuing Bank of such Letter of Credit (which such Issuing Bank may do or not do in its sole and absolute discretion), effective as of the Expiration Date, whereby such Letter of Credit shall thereafter be governed by such agreement and shall cease to be governed by this Agreement, whereupon all participations of the Lenders in such Letter of Credit shall automatically terminate; provided, however, that such agreement, cessation and termination shall not affect the obligation of the Borrower with respect to amounts accrued or owing at such time under the Loan Documents with respect to such Letter of Credit. The provisions of this paragraph shall apply to each Letter of Credit outstanding on the Expiration Date and having an expiration date thereafter.

Any Issuing Bank may be replaced at any time, or a Lender or other financial institution may be added as an Issuing Bank, by written agreement between the Borrower and the Administrative Agent; provided, however, that (i) each Issuing Bank shall be either a Lender or another financial institution satisfactory to the Administrative Agent, and (ii) without limiting the effect of the foregoing clause (i), the Administrative Agent shall review any such proposed agreement for form only and not with respect to the identity of any successor or additional Issuing Bank or, if applicable, the identity of the Issuing Bank to be replaced. The Administrative Agent shall notify the Lenders of any such replacement or addition of an Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.06(b)(ii) and shall return to such Issuing Bank each Letter of Credit issued by such Issuing Bank. From and after the effective date of any such replacement or addition of an Issuing Bank, (A) the successor or additional Issuing Bank shall have all of the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit to be issued by it on such effective date or thereafter, and (B) references herein to “Issuing Bank” shall be deemed to refer to such successor or additional Issuing Bank and/or to any previous Issuing Bank, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall continue to have all of the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it before such replacement, but such replaced Issuing Bank shall not be required to issue additional Letters of Credit.

Each “Letter of Credit” outstanding under the 2004 Credit Agreement on the Closing Date shall automatically, without further action on the part of the Borrower, the applicable Issuing Bank or any other person, be deemed to have been issued under this Section 2.05 and shall be a Letter of Credit under this Agreement for all purposes.

Section 2.06 Fees.

The Borrower agrees to pay to each Lender, through the Administrative Agent, on the first Business Day of January, April, July and October of each year and on the date on which the Commitment of such Lender shall be reduced or terminated as provided herein, a facility fee at the Applicable Rate (a “Facility Fee”) on the daily amount of the Commitment of such Lender during the preceding quarter (or shorter period commencing with the date hereof or ending with the Expiration Date or the date on which the Commitment of such Lender shall be reduced or terminated); provided, however, that no Lender shall be entitled to receive any Facility Fee with respect to the unused portion of its Commitment (i.e., its Commitment minus its Revolving Credit Exposure) for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any Facility Fee that it otherwise would have been required to pay to that Lender with respect to the unused portion of its Commitment). The Facility Fees shall accrue on each day at a rate per annum equal to the Applicable Rate in effect on such day. All Facility Fees shall be computed on the basis of a year of 365 or 366 days, as the case may be, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The Facility Fee due to each Lender shall commence to accrue on the date of this Agreement and shall cease to accrue on the date on which the Commitment of such Lender shall be terminated as provided herein.

The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender, a participation fee with respect to its participations in Letters of Credit, which fee shall accrue at the Applicable Rate (an “LC Participation Fee”) on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to each Issuing Bank, a fronting fee for Letters of Credit issued by such Issuing Bank, which fee shall accrue at the rate of 0.20% per annum on the average daily amount of such Issuing Bank’s Issuing Bank Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements of such Issuing Bank) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any Issuing Bank Exposure (with the calculation and payment of such fee to be determined by such Issuing Bank and the Borrower). LC Participation Fees and Letter of Credit fronting fees shall be payable quarterly in arrears on the first Business Day of January, April, July and October of each year and on the date on which the Commitments terminate as provided herein; provided, however, that all such fees accruing after the date on which the Commitments terminate shall be

payable on demand. All LC Participation Fees and Letter of Credit fronting fees shall be computed on the basis of a year of 365 or 366 days, as the case may be, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day) during the period in question.

The Borrower agrees to pay to the Administrative Agent, for its own account, the fees separately agreed between the Administrative Agent and the Borrower.

Once paid, none of the Fees shall be refundable under any circumstances.

Section 2.07 Interest on Loans; Term SOFR Conforming Changes.

Subject to the provisions of Section 2.08, the Loans comprising each ABR Borrowing shall bear interest at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate.

Subject to the provisions of Section 2.08, the Loans comprising each SOFR Borrowing shall bear interest at a rate per annum equal to Adjusted Term SOFR for the Interest Period in effect for such Borrowing plus the Applicable Rate.

Interest on each Loan shall be payable on the Interest Payment Dates applicable to such Loan except as otherwise provided in this Agreement.

Interest computed on the basis of the Alternate Base Rate (including interest payable on overdue amounts under Section 2.08) shall be computed on the basis of a year of 365 or 366 days, as the case may be, for the actual number of days elapsed so long as the Prime Rate is the applicable rate for calculation of the Alternate Base Rate, and on the basis of a year of 360 days for the actual number of days elapsed so long as the Federal Funds Effective Rate is the applicable rate for calculation of the Alternate Base Rate. Interest computed on the basis of Adjusted Term SOFR (including interest payable on overdue amounts under Section 2.08) shall be computed on the basis of a year of 360 days for the actual number of days elapsed.

The applicable Alternate Base Rate or Adjusted Term SOFR for each Interest Period or day within an Interest Period, as the case may be, shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

In connection with the use or administration of Term SOFR, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document.The Administrative Agent will promptly notify the Borrower and the Lenders of the effectiveness of any Conforming Changes in connection with the use or administration of Term SOFR.

Section 2.08 Default Interest. If the Borrower shall default in the payment of the principal of or interest on any Loan or any other amount becoming due under the Loan Documents, by acceleration or otherwise, the Borrower shall on demand from time to time pay interest, to the extent permitted by law, on such defaulted amount up to (but not including) the date of actual payment (after as well as before judgment) at a rate per annum equal to the Alternate Base Rate plus the Applicable Rate plus 2% (except that the interest rate applicable to an overdue amount of principal of a SOFR Borrowing that became due on a day other than on the last day of the Interest Period applicable thereto shall, for the period until the last day of such Interest Period, be equal to 2% above the rate that would otherwise be applicable thereto during such Interest Period).

Section 2.09 Inability to Determine Rates. Subject to Section 10.20, if, on or prior to the firstday of any Interest Periodfor any SOFR Loan:

the Administrative Agent determines (which determination shall be conclusive absent manifest error) that “Term SOFR” or “Adjusted Term SOFR”, as applicable, cannot be determined pursuant to the definition thereof; or

the Required Lenders determine that for any reason in connection with any request for a SOFR Loan or a conversion thereto or continuation thereof that Term SOFR or Adjusted Term SOFR, as applicable, for any requested Interest Period with respect to such SOFR Loan does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loan, and the Required Lenders have provided notice of such determination to the Administrative Agent;

then, in each case, the Administrative Agent will promptly so notify the Borrower and each Lender.

Upon notice thereof by the Administrative Agent to the Borrower, any obligation of the Lenders to make SOFR Loans, and any right of the Borrower to refinance all or any part of any Borrowing with a new SOFR Borrowing, shall be suspended (to the extent of the affected SOFR Loans or affected Interest Periods) until the Administrative Agent (with respect to clause (b) above, at the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, (i) the Borrower may revoke any pending request for a borrowing of SOFR Loans or a refinancing of all or any part of any Borrowing with a new SOFR Borrowing (to the extent of the affected SOFR Loans or affected Interest Periods) or, failing that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of ABR Loans in the amount specified therein and (ii) any outstanding affected SOFR Loans will be deemed to have been converted into ABR Loans at the end of the applicable Interest Period. Upon any such conversion, the Borrower shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to Section 2.14. Subject to Section 10.20, if the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that “Term SOFR” or “Adjusted Term SOFR” cannot be determined pursuant to the definition thereofon any given day, the interest rate on ABR Loans shall be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate” until the Administrative Agent revokes such determination.

Section 2.10 Termination, Reduction and Increase in Commitments.

The Commitments shall automatically terminate on the Expiration Date.

Upon at least three Business Days’ prior irrevocable notice to the Administrative Agent, the Borrower may at any time in whole permanently terminate, or from time to time in part permanently reduce, the unused portion of the Commitments; provided, however, that (i) each partial reduction of the Commitments shall be in the aggregate amount of $5,000,000 or a higher whole-integer multiple thereof, and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the sum of the Revolving Credit Exposures would exceed the total Commitments.

At any time following the date of this Agreement and prior to the Expiration Date, the total Commitments may, at the option of the Borrower, be increased by an aggregate amount not in excess of $100,000,000, either by newly establishing or increasing Commitments of one or more persons that become Additional Commitment Lenders pursuant to this Section 2.10(c); provided that (i) each such Additional Commitment Lender shall be selected or approved by the Borrower and shall be reasonably acceptable to the Administrative Agent and the Issuing Banks, (ii) no Lender shall have an obligation to become such an Additional Commitment Lender, (iii) no Default or Event of Default shall exist immediately prior to or after the effective date of each such increase in the total Commitments, (iv) the representations and warranties set forth in Article III shall be true and correct in all material respects on and as of the effective date of each such increase in the total Commitments with the same effect as if made on and as of such date, except to the extent that such representations and warranties expressly relate to an earlier date, (v) each such newly established Commitment shall be in an amount equal to or greater than $5,000,000, (vi) each increase in the total Commitments pursuant to this Section 2.10(c) shall be in the aggregate amount of $10,000,000 or a whole-integer multiple of $5,000,000 in excess thereof, (vii) the aggregate amount of increases in the total Commitments pursuant to this Section 2.10(c) shall not exceed $100,000,000, and (viii) no such newly established Commitment or increase in a Commitment shall become effective unless and until the Borrower, the Administrative Agent, the Issuing Banks and the relevant Additional Commitment Lender shall have executed and delivered an agreement substantially in the form of Exhibit D (a “Commitment Increase Supplement”) with respect thereto, (B) such Additional Commitment Lender, if not already a Lender, shall have delivered an Administrative Questionnaire to the Administrative Agent, and (C) if the obligations of the Borrower under this Agreement are then secured by the First Mortgage, the Administrative Agent shall have received a substitute First Mortgage Bond in an amount equal to the total Commitments after giving effect to the increase in the total Commitments, together with a supplemental indenture, a bond delivery agreement, mortgage title insurance, legal opinions and other certificates and documents with respect thereto comparable to those delivered pursuant to Section 4.02(a) with respect to the First Mortgage Bond issued under the First Mortgage and delivered to the Administrative Agent on the Closing Date, in each case in form and substance satisfactory to the Administrative Agent. Upon compliance with the provisions of this Section 2.10(c), each Additional Commitment Lender

hereunder shall have the Commitment specified in its Commitment Increase Supplement and, if not already a Lender, shall constitute a “Lender” hereunder.

On the effective date of each increase in the total Commitments pursuant to Section 2.10(c), each relevant Additional Commitment Lender shall purchase, as an assignment from each other Lender, the portion of such other Lender’s Loans, unreimbursed LC Disbursements and participations in Letters of Credit outstanding at such time such that, after giving effect to such assignments, the respective aggregate amount of Loans, unreimbursed LC Disbursements and participations in Letters of Credit of each Lender shall be equal to such Lender’s Pro Rata Share of the aggregate Loans, unreimbursed LC Disbursements and participations in Letters of Credit outstanding. The purchase price for the Loans, unreimbursed LC Disbursements and participations in Letters of Credit so assigned shall be the sum of (i) the principal amount of the Loans and unreimbursed LC Disbursements so assigned plus the amount of accrued and unpaid interest thereon as of the date of assignment and (ii) the amount of accrued and unpaid LC Participation Fees as of the date of assignment on the participations in Letters of Credit so assigned. Each such Additional Commitment Lender shall pay the aggregate purchase price payable by it to the Administrative Agent on the effective date of the corresponding increase in the total Commitments, and the Administrative Agent shall promptly forward to each other Lender the portion thereof payable to it. Upon payment of such purchase price, each other Lender shall be automatically deemed to have sold and made such an assignment to each such Additional Commitment Lender and shall, to the extent of the interest assigned, be released from its obligations under the Loan Documents, and each such Additional Commitment Lender shall be automatically deemed to have purchased and assumed such an assignment from each other Lender and, if not already a Lender hereunder, shall be a party hereto and, to the extent of the interest assigned, have the rights and obligations of a Lender under the Loan Documents.

Section 2.11 Prepayment. The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, upon at least three (3) U.S. Government Securities Business Days’ prior notice to the Administrative Agent, in the case of a prepayment of a SOFR Borrowing, and upon at least one Business Day’s prior notice, in the case of a prepayment of an ABR Borrowing; provided, however, that each partial prepayment shall be in the amount of $1,000,000 or a higher whole-integer multiple thereof. Each notice of prepayment shall specify the prepayment date and the principal amount of each Borrowing (or portion thereof) to be prepaid, shall be irrevocable and shall commit the Borrower to prepay such Borrowing by the amount stated therein on the date stated therein. All prepayments under this Section 2.11 shall be subject to Section 2.14 but otherwise without premium or penalty. All prepayments under this Section 2.11 shall be accompanied by accrued interest on the principal amount being prepaid to (but excluding) the date of payment.

Section 2.12 Increased Costs.

If any Change in Law shall:

(i)

impose, modify or deem applicable any reserve (including pursuant to regulations issued from time to time by the Board for determining the maximum reserve requirement (including any emergency, special, supplemental or other marginal reserve requirement) with respect to eurocurrency funding (currently referred to as “Eurocurrency liabilities” in Regulation D)), special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender or any Issuing Bank;

(ii)

subject any Recipient to any Taxes (other than (i) Taxes imposed on or with respect to any payment made by the Borrower under any Loan Document, which shall be solely governed by Section 2.18, and (ii) Other Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)

impose on any Lender or any Issuing Bank any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation in any such Loan or Letter of Credit;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing, refinancing or maintaining any Loan or of maintaining its obligation to make or refinance any such Loan, or to increase the cost to such Lender, such Issuing Bank or such other Recipient of issuing or maintaining any Letter of Credit or purchasing or maintaining a participation therein or to reduce the amount of any sum received or receivable by such Lender, such Issuing Bank or such other Recipient hereunder or under any Notes (whether of principal, interest or otherwise) by an amount deemed by such Lender, such Issuing Bank or such other Recipient to be material, then the Borrower will pay to such Lender, such Issuing Bank or such other Recipient, as the case may be, upon demand such additional amount or amounts as will compensate such Lender, such Issuing Bank or such other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

If any Lender or Issuing Bank shall have determined that the applicability of any law, rule, regulation, agreement or guideline adopted after the date hereof regarding capital adequacy or liquidity requirements, or any change in any of the foregoing or the adoption after the date hereof of any change in any law, rule, regulation, agreement or guideline existing on the date hereof or in the interpretation or administration of any of the foregoing by any Governmental Authority charged with the interpretation or administration thereof, or compliance by any Lender or Issuing Bank (or any lending office thereof) or any Lender’s or Issuing Bank’s holding company with any request or directive regarding capital adequacy or liquidity requirements (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s or Issuing Bank’s capital or on the capital of such Lender’s or Issuing Bank’s holding company, if any, with respect to this Agreement, any Loan or any Letter of Credit or participation therein to a level below that which such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company could have achieved but for such applicability,

adoption, change or compliance (taking into consideration such Lender’s or Issuing Bank’s policies and the policies of such Lender’s or Issuing Bank’s holding company with respect to capital adequacy or liquidity) by an amount deemed by such Lender or Issuing Bank to be material, then from time to time the Borrower shall pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company for any such reduction suffered. It is acknowledged that this Agreement is being entered into by the Lenders and the Issuing Banks on the understanding that the Lenders and the Issuing Banks will not be required to maintain capital against their obligations to make Loans or issue Letters of Credit or purchase participations therein under currently applicable laws, regulations and regulatory guidelines. In the event that any Lender or Issuing Bank shall be advised by any Governmental Authority, or shall otherwise determine on the basis of pronouncements of any Governmental Authority, that such understanding is incorrect, it is agreed that each such Lender or Issuing Bank will be entitled to make claims under this paragraph based upon market requirements prevailing on the date hereof for commitments under comparable credit facilities against which capital is required to be maintained.

A certificate of a Lender or Issuing Bank setting forth in reasonable detail such amount or amounts as shall be necessary to compensate such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company as specified in paragraph (a) or (b) above, as the case may be, and the manner in which such Lender or Issuing Bank has determined the same, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or Issuing Bank, as the case may be, the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same.

Failure on the part of any Lender or Issuing Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital with respect to any period shall not constitute a waiver of such Lender’s or Issuing Bank’s right to demand compensation with respect to such period or any other period; provided that the Borrower shall not be required to compensate a Lender or Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender or Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s or Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof). The protection of this Section shall be available to each Lender and Issuing Bank regardless of any possible contention of the invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition which shall have occurred or been imposed.

For purposes of this Agreement, notwithstanding anything in this Agreement to the contrary, the Dodd-Frank Act and all rules, regulations, interpretations, agreements,

guidelines, directives and requests in connection therewith are deemed to have been adopted, and to have gone into effect, after the date of this Agreement, regardless of the date on which the same were actually adopted or went into effect.

Section 2.13 Illegality. If any Lender determines that any Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable lending office to make, maintain or fund Loans whose interest is determined by reference to SOFR, the Term SOFR Reference Rate, Adjusted Term SOFR or Term SOFR, or to determine or charge interest based upon SOFR, the Term SOFR Reference Rate, Adjusted Term SOFR or Term SOFR, then, upon notice thereof by such Lender to the Borrower (through the Administrative Agent) (an “Illegality Notice”), (a) any obligation of the Lenders to make SOFR Loans, and any right of the Borrower to refinance all or any part of any Borrowing with a new SOFR Borrowing, shall be suspended, and (b) the interest rate on ABR Loans shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate”, in each case until each affected Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of an Illegality Notice, the Borrower shall, if necessary to avoid such illegality, upon demand from any Lender (with a copy to the Administrative Agent), prepay or, if applicable, refinance all SOFR Loans with ABR Loans (the interest rate on which ABR Loans shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to clause (c) of the definition of “Alternate Base Rate”), on the last day of the Interest Period therefor, if all affected Lenders may lawfully continue to maintain such SOFR Loans to such day, or immediately, if any Lender may not lawfully continue to maintain such SOFR Loans to such day. Upon any such prepayment or refinancing, each applicable Borrower shall also pay accrued interest on the amount so prepaid or refinanced, together with any additional amounts required pursuant to Section 2.14.

Section 2.14 Compensation for Losses. In the event of (a) the payment of any principal of any SOFR Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion or refinancing of any SOFR Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (c) the failure by the Borrower to borrow, convert, continue, refinance or prepay any SOFR Loan on the date specified in any notice delivered by the Borrower pursuant hereto, or (d) the assignment of any SOFR 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 2.19(b), then, in any such event, the Borrower shall compensate each Lender for any loss, cost and expense attributable to such event, including any loss, cost or expense arising from the liquidation or redeployment of funds or from any fees payable. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section, and the manner in which such Lender has determined the same, 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) Business Days after receipt thereof.

Section 2.15 Pro Rata Treatment. Except as required under Sections 2.12, 2.14 and 2.18, each Borrowing, each payment or prepayment of principal of any Borrowing or LC Disbursement, each payment of interest on the Loans or LC Disbursements, each payment of the Fees, and each reduction of the Commitments shall be allocated among the Lenders in accordance with their

respective Pro Rata Shares. Each Lender agrees that, in computing such Lender’s portion of any Borrowing to be made hereunder, the Administrative Agent may, in its discretion, round each Lender’s Pro Rata Share of such Borrowing to the next higher or lower whole-dollar amount.

Section 2.16 Sharing of Setoffs. Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim against the Borrower, or pursuant to a secured claim under Section 506 of Title 11 of the United States Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable bankruptcy, insolvency or other similar law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of its Loans or participations in LC Disbursements as a result of which the unpaid principal portion of its Loans or participations in LC Disbursements shall be proportionately less than the unpaid principal portion of the Loans or participations in LC Disbursements of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a participation in the Loans or participations in LC Disbursements of such other Lender (“Sharing Participations”), so that (a) the aggregate unpaid principal amount of the Loans, participations in LC Disbursements and Sharing Participations held by each Lender shall be in the same proportion to the aggregate unpaid principal amount of all Loans and LC Disbursements then outstanding as (b) the principal amount of its Loans, participations in LC Disbursements and Sharing Participations prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the principal amount of all Loans and LC Disbursements outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that, if any such purchase or purchases or adjustments shall be made pursuant to this Section and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. The Borrower expressly consents to the foregoing arrangements and agrees that any Lender holding a participation in a Loan or in a participation in an LC Disbursement deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to any and all moneys owing by the Borrower to such Lender by reason thereof as fully as if such Lender had made a Loan directly to the Borrower or had acquired a participation in an LC Disbursement directly from the applicable Issuing Bank, as the case may be, in the amount of such participation.

Section 2.17 Payments.

The Borrower shall make each payment (including for principal of or interest on any Borrowing, reimbursements of LC Disbursements, Fees and other amounts) hereunder and under any other Loan Document not later than 12:00 noon, New York, New York time, on the date when due in dollars to the Administrative Agent at its offices at 1221 Avenue of the Americas, New York, New York 10020, in immediately available funds.

Whenever any payment (including for principal of or interest on any Borrowing, reimbursements of LC Disbursements, Fees and other amounts) hereunder or under any other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next

succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or Fees, if applicable.

Section 2.18 Taxes.

Any and all payments by the Borrower hereunder and under any other Loan Document shall be made, in accordance with Section 2.17, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding (i) taxes imposed on the net income of the Administrative Agent, any Lender or any Issuing Bank (or any transferee or assignee thereof, including a participation holder (any such entity being called a “Transferee”)) and franchisetaxes imposed on the Administrative Agent, any Lender or any Issuing Bank (or any Transferee) by the United States or any jurisdiction under the laws of which the Administrative Agent or any such Lender or Issuing Bank (or Transferee) or the applicable lending office, is organized or any political subdivision thereof, and (ii) any U.S. federal withholding taxes imposed on amounts payable to or for the account of such Lender or Issuing Bank pursuant to the law in effect on the date on which (A) such Lender or Issuing Bank becomes a party to this Agreement or, with respect to a Loan attributable to a transferred or increased Commitment of a Lender, the date such Lender acquired its transferred or increased Commitment (in each case, other than pursuant to an assignment request by the Borrower under Section 2.19(b)) or (B) such Lender or Issuing Bank changes its lending office, except in each case to the extent that amounts with respect to such taxes were payable to such Lender’s or Issuing Bank’s assignor immediately before such Lender or Issuing Bank became a party hereto or to such Lender or Issuing Bank immediately before it changed its lending office (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable under any Loan Document to any Lender or Issuing Bank (or Transferee) or the Administrative Agent, (i) the sum payable shall be increased by the amount necessary so that after making all required deductions of Taxes (including deductions applicable to additional sums payable under this Section 2.18) such Lender or Issuing Bank (or Transferee) or the Administrative Agent (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions of Taxes been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law; provided, however, that no Transferee of any Lender shall be entitled to receive any greater payment under this paragraph (a) than such Lender would have been entitled to receive with respect to the rights assigned, participated or otherwise transferred except to the extent that such greater payment arises from circumstances not in existence at the time such assignment, participation or transfer shall have been made.

In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made under any Loan Document or from the execution, delivery or

registration of, or otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as “Other Taxes”).

The Borrower will indemnify each Lender (or Transferee), each Issuing Bank (or Transferee) and the Administrative Agent for the full amount of any Taxes and Other Taxes paid by such Lender or Issuing Bank (or Transferee) or the Administrative Agent, as the case may be, and any liability (including penalties, interest and reasonable expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted by the relevant taxing authority or other Governmental Authority. Such indemnification shall be made within 30 days after the date any Lender or Issuing Bank (or Transferee) or the Administrative Agent, as the case may be, makes written demand therefor. If a Lender or Issuing Bank (or Transferee) or the Administrative Agent shall become aware that it is entitled to receive a refund in respect of Taxes or Other Taxes as to which it has been indemnified by the Borrower pursuant to this Section 2.18, it shall promptly notify the Borrower of the availability of such refund and shall, within 30 days after receipt of a request by the Borrower, apply for such refund at the Borrower’s expense.

If any Lender or Issuing Bank (or Transferee) or the Administrative Agent receives a refund in respect of any Taxes or Other Taxes as to which it has been indemnified by the Borrower pursuant to this Section 2.18, it shall promptly notify the Borrower of such refund and shall repay such refund to the Borrower (to the extent of amounts that have been paid by the Borrower under this Section 2.18 with respect to such refund) within 30 days (or promptly upon receipt, if the Borrower has requested application for such refund pursuant hereto), net of all reasonable out-of-pocket expenses of such Lender or Issuing Bank (or Transferee) and without interest (other than interest included in such refund); provided that the Borrower, upon the request of such Lender or Issuing Bank (or Transferee) or the Administrative Agent, agrees to return such refund (plus penalties, interest or other charges) to such Lender or Issuing Bank (or Transferee) or the Administrative Agent in the event such Lender or Issuing Bank (or Transferee) or the Administrative Agent is required to repay such refund. Nothing contained in this paragraph (d) shall require any Lender or Issuing Bank (or Transferee) or the Administrative Agent to make available any of its tax returns (or any other information relating to its taxes which it deems to be confidential); provided that Borrower, at its expense, shall have the right to receive an opinion from a firm of independent public accountants of recognized national standing acceptable to the Borrower that the amount due hereunder is correctly calculated.

Within 30 days after the date of any payment of Taxes or Other Taxes withheld by the Borrower in respect of any payment to any Lender or Issuing Bank (or Transferee) or the Administrative Agent, the Borrower will furnish to the Administrative Agent, at its address referred to in Section 10.01, the original or a certified copy of a receipt received by the Borrower evidencing payment thereof.

Without prejudice to the survival of any other agreement contained herein, the agreements and obligations contained in this Section 2.18 shall survive the payment in full of the principal of and interest on all Loans made hereunder.

On or prior to the execution of this Agreement and on or before the transfer to a Transferee, the Administrative Agent shall notify the Borrower of each Lender’s or Issuing Bank’s (or Transferee’s) address. On or prior to each Lender’s or Issuing Bank’s (or Transferee’s) first Interest Payment Date, and from time to time as required by law, each Lender or Issuing Bank (or Transferee) that is not a United States person within the meaning of Section 7701(a)(30) of the Code (a “Non-U.S. Person”) shall, if legally able to do so, deliver to the Borrower and the Administrative Agent (i) one duly completed and executed copy of United States Internal Revenue Service Form W-8BEN or W-8BEN-E (as applicable) or W-8ECI, (ii) if claiming exemption from United States Federal withholding tax pursuant to Section 871(h) or 881(c) of the Code, one duly completed and executed copy of a United States Internal Revenue Service Form W-8BEN or W-8BEN-E (as applicable) and a certificate representing that such Non-U.S. Person is not a bank for purposes of Section 881(c) of the Code, is not a 10 percent shareholder (within the meaning of Section 871(h)(3)(b) of the Code) of the Borrower and is not a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Code) or (iii) any successor applicable form of any thereof, establishing in each case that such Lender or Issuing Bank (or Transferee) is entitled to receive payments under the Loan Documents payable to it without deduction or withholding of any United States Federal income taxes, or is subject to a reduced rate thereof. Unless the Borrower and the Administrative Agent have receivedforms or other documents satisfactory to them indicating that such payments under the Loan Documents are not subject to United States Federal withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, the Borrower shall withhold taxes from such payments at the applicable statutory rate.

The Borrower shall not be required to pay any additional amounts to any Lender or Issuing Bank (or Transferee) in respect of United States Federal withholding tax pursuant to paragraph (a) above if the obligation to pay such additional amounts would not have arisen but for a failure by such Lender or Issuing Bank (or Transferee) to comply with the provisions of paragraph (g) above; provided, however, that the Borrower shall be required to pay those amounts to any Lender or Issuing Bank (or Transferee) that it was required to pay hereunder prior to the failure of such Lender or Issuing Bank (or Transferee) to comply with the provisions of such paragraph (g).

Notwithstanding anything to the contrary in this Section 2.18, the term “Taxes” shall not include U.S. federal withholding taxes imposed under FATCA. If a payment made to a Lender or Issuing Bank under any Loan Document would be subject to U.S. federal withholding tax imposed by FATCA if such Lender or Issuing Bank were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender or Issuing Bank shall deliver to the Borrower and the Administrative Agent at the time or

times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender or Issuing Bank has complied with such Lender’s or Issuing Bank’s obligations under FATCA or to determine the amount, if any, to deduct and withhold from such payment. For purposes of this Section 2.18(i), “FATCA” shall include any amendments made to FATCA after the Amendment No. 3 Effective Date. If any form or certification a Lender or Issuing Bank previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

Section 2.19 Termination or Assignment of Commitments under Certain Circumstances.

Any Lender or Issuing Bank (or Transferee) claiming any additional amounts payable pursuant to Section 2.12 or 2.18 or exercising its rights under Section 2.13 shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or to change the jurisdiction of its applicable lending office if the making of such a filing or change would avoid the need for or reduce the amount of any such additional amounts which may thereafter accrue or avoid the circumstances giving rise to such exercise and would not, in the sole determination of such Lender or Issuing Bank (or Transferee), be otherwisedisadvantageous to such Lender or Issuing Bank (or Transferee).

In the event that any Lender shall have delivered a notice or certificate pursuant to Section 2.13, or the Borrower shall be required to make additional payments under Section 2.12 or 2.18 to any Lenderor Issuing Bank (or Transferee) or to the Administrative Agent with respect to any Lender or Issuing Bank (or Transferee), the Borrower shall have the right, at its own expense, upon notice to such Lender or Issuing Bank (or Transferee) and the Administrative Agent (and, if a Commitment is being terminated or assigned, the Issuing Banks), (i) to terminate the Commitment of such Lender or Issuing Bank (or Transferee) or (ii) to require such Lender or Issuing Bank (or Transferee) to transfer and assign without recourse (in accordance with and subject to the restrictions contained in Section 10.04) all its interests, rights and obligations under the Loan Documents to another financial institution which shall assume such obligations; provided that (A) no such termination or assignment shall conflict with any law, rule or regulation or order of any Governmental Authority and (B) the Borrower or the assignee, as the case may be, shall pay to the affected Lender or Issuing Bank (or Transferee) in immediately available funds on the date of such termination or assignment the principal of and interest accrued to the date of payment on the Loans made by it hereunder and all other amounts accrued for its account and owed to it under the Loan Documents and, in the case of a termination or assignment

by an Issuing Bank, shall cause all Letters of Credit issued by such Issuing Bank to be surrendered for cancellation on or prior to the date of such termination or assignment.

Section 2.20 Extension of Expiration Date.

If no Event of Defaulthas occurred and is continuing,the Borrower may request, by simultaneous notice to the Administrative Agent and each Lender given after the Amendment No. 5 Effective Date and no later than 60 days before the Expiration Date applicable on the date of such notice (the “Current Expiration Date”), that the Lenders extend their respective Commitments for an additional period of one year. If a Lender agrees, in its sole and absolute discretion, to so extend its Commitment, it will give notice to the Administrative Agent of its decision to do so within 30 days after the Borrower’s delivery of notice to the Administrative Agent and the Lenders requesting extension of the Current Expiration Date. Promptly after expiration of such 30-day period, the Administrative Agent will notify the Borrower and each Lender as to the Lenders (each an “Extending Lender”) from which it has received such a notice agreeing to so extend. Any failure by a Lender to so notify the Administrative Agent shall be deemed to be a decision by such Lender not to so extend its Commitment.

If all Lenders elect to so extend their respective Commitments, and provided that the additional conditions specified in Section 4.03 shall have been satisfied, then on the Current Expiration Date the Expiration Date shall automatically be extended by a period of one year.

If, at the time the Administrative Agent gives the notice contemplated by Section 2.20(a) to the Borrower and the Lenders, the Commitments of the Extending Lenders aggregate at least 66-2/3%, but less than 100%, of the Commitments of all of the Lenders at such time (the “Existing Commitments”), then, notwithstanding anything in Section 10.08(b) to the contrary, (i) as to each Extending Lender, on the Current Expiration Date the Expiration Date shall automatically be extended by a period of one year, provided that the additional conditions specified in Section 4.03 shall have been satisfied, (ii) the Expiration Date shall remain unchanged as to each Lenderthat is not an Extending Lender (each a “Terminating Lender”), (iii) each Terminating Lender’s Commitment shall terminate on the Current Expiration Date, and (iv) on the Current Expiration Date the Borrower shall (A) pay the outstanding Loans owed to each Terminating Lender and all other amounts owed to each Terminating Lender and (B) deposit into an account with the Administrative Agent an amount in cash equal to the aggregate LC Exposure of the Terminating Lenders plus any accrued and unpaid interest thereon, to be held and applied as provided in Section 2.05(i). If, at the time the Administrative Agent gives the notice contemplated by Section 2.20(a) to the Borrower and the Lenders, the Commitments of the Extending Lenders aggregate less than 66-2/3% of the Existing Commitments, then none of the Commitments (including the Commitment of any Extending Lender) shall be extended, and the Expiration Date shall remain unchanged.

The Borrowermay use the process contemplated by this Section 2.20, at any time or times after the Amendment No. 5 Effective Date, no more than twice; provided, however, that no extension of the Expiration Date shall be permitted that would cause the remaining term until the Expiration Date to exceed five years at any time.

If, at any time that the Administrative Agent gives a notice contemplated by Section 2.20(a) to the Borrower and the Lenders, the Commitments of the Extending Lenders aggregate at least 66-2/3% but less than 100% of the then Existing Commitments, the Borrower shall have the right to replace the Commitments of the Terminating Lenders by either newly establishing or increasing Commitments of one or more persons that become Additional Commitment Lenders pursuant to this Section 2.20(e); provided that (i) each such Additional Commitment Lender shall be selected or approved by the Borrower and shall be reasonably acceptable to the Administrative Agent and the Issuing Banks, (ii) no Extending Lender shall have an obligation to become such an Additional Commitment Lender, (iii) the additional conditions specified in Section 4.03 shall have been satisfied, (iv) each such newly established Commitment shall be in an amount equal to or greater than $5,000,000, (v) the aggregate of such newly established Commitments and increases in Commitments shall not exceed the aggregate Commitments of the Terminating Lenders, and (vi) no such newly established Commitment or increase in a Commitment shall become effective unless and until (A) the Borrower, the Administrative Agent, the Issuing Banks and the relevant Additional Commitment Lender shall have executed and delivered an agreement substantially in the form of Exhibit E (a “Commitment Extension Supplement”) with respect thereto, in each case in form and substance satisfactory to the Administrative Agent, and (B) such Additional Commitment Lender, if not already a Lender, shall have delivered an Administrative Questionnaire to the Administrative Agent. Upon compliance with the provisions of this Section 2.20(e), each Additional Commitment Lender hereunder shall have the Commitment specified in its Commitment Extension Supplement and, if not already a Lender, shall constitute a “Lender” hereunder.

On the effective date of each replacement of all or a portion of one or more Commitments of Terminating Lenders pursuant to Section 2.20(e), each relevant Additional Commitment Lender shall purchase, as an assignment from each other Lender, the portion of such other Lender’s Loans, unreimbursed LC Disbursements and participations in Letters of Credit outstanding at such time such that, after giving effect to such assignments, the respective aggregate amount of Loans, unreimbursed LC Disbursements and participations in Letters of Credit of each Lender shall be equal to such Lender’s Pro Rata Share of the aggregate Loans, unreimbursed LC Disbursements and participations in Letters of Credit outstanding. The purchase price for the Loans, unreimbursed LC Disbursements and participations in Letters of Credit so assigned shall be the sum of (i) the principal amount of the Loans and unreimbursed LC Disbursements so

assigned plus the amount of accrued and unpaid interest thereon as of the date of assignment and (ii) the amount of accrued and unpaid LC Participation Fees as of the date of assignment on the participations in Letters of Credit so assigned. Each such Additional Commitment Lender shall pay the aggregate purchase price payable by it to the Administrative Agent on the effective date of the corresponding replacement of all or a portion of one or more Commitments of Terminating Lenders, and the Administrative Agent shall promptly forward to each other Lender the portion thereof payable to it. Upon payment of such purchase price, each other Lender shall be automatically deemed to have sold and made such an assignment to each such Additional Commitment Lender and shall, to the extent of the interest assigned, be released from its obligations under the Loan Documents, and each such Additional Commitment Lender shall be automatically deemed to have purchased and assumed such an assignment from each other Lender and, if not already a Lender hereunder, shall be a party hereto and, to the extent of the interest assigned, have the rights and obligations of a Lender under the Loan Documents.

Section 2.21 Defaulting Lenders.

If any Letters of Credit are outstanding at the time a Lender becomes a Defaulting Lender, and the Commitments have not been terminated in accordance with Article VII, then:

(i)

so long as no Default or Event of Default has occurred and is continuing, all or any part of the LC Exposure of such Defaulting Lender shall be reallocated among the Lenders that are not Defaulting Lenders (“non-Defaulting Lenders”) in accordance with their respective Pro Rata Shares (disregarding any Defaulting Lender’s Commitment), but only to the extent that the sum of (A) the aggregate principal amount of all Loans made by such non-Defaulting Lenders and outstanding at such time, plus (B) the aggregate amount of such non-Defaulting Lenders’ LC Exposures (before giving effect to the reallocation contemplated herein), plus (C) such Defaulting Lender’s LC Exposure does not exceed the total of all non- Defaulting Lenders’ Commitments, and in no event shall the sum of the aggregate principal amount of all Loans made by a non-Defaulting Lender plus its LC Exposure after giving effect to the reallocation described in this clause (i) exceed such non-Defaulting Lender’s Commitment;

(ii)

if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall, within one Business Day following notice by any Issuing Bank, cash-collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) by providing cash collateral to such Issuing Bank in accordance with Section 2.05(i); provided, however, that, so long as no Default or Event of Default has occurred and is continuing, such cash collateral shall be released promptly upon the earliest of (A) the full reallocation of the LC Exposure among non-Defaulting Lenders in accordance with clause (i) above, (B) the

termination of the Defaulting Lender status of the applicable Lender and (C) such Issuing Bank’s good-faith determination that there exists excess cash collateral (in which case, the amount equal to such excess cash collateral shall be released);

(iii)

if and to the extent that the LC Exposures of the non-Defaulting Lenders are reallocated pursuant to this Section2.21(a), then the LC Participation Fees payable to the Lenders pursuantto Section 2.06(b)shall be adjustedin accordance with such non-Defaulting Lenders’ reallocated percentage of the total LC Exposure; or

(iv)

if and to the extent that any Defaulting Lender’s LC Exposure is neither reallocated nor cash-collateralized pursuant to this Section 2.21(a), then, without prejudice to any other rights or remedies of any Issuing Bank or any Lender hereunder, all LC Participation Fees payable under Section 2.06(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the applicable Issuing Bank until such Defaulting Lender’s LC Exposure is fully reallocated and/or cash-collateralized.

So long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, renew, extend or otherwise amend any Letter of Credit unless it is satisfied that (i) its exposure in respect of all outstanding Letters of Credit is fully covered by the Commitments of non-Defaulting Lenders and/or cash collateral provided by the Borrower in accordance with Section 2.21(a), and (ii) participating interests in any such newly issued or increased Letter of Credit will be allocated among non-Defaulting Lenders and/or cash- collateralized in a manner consistent with Section 2.21(a) (and Defaulting Lenders shall not participate therein).

No Commitment of any Lender shall be increased or otherwise affected, and, except as otherwise expressly provided in this Section 2.21, the performance by the Borrower of its obligations under this Agreement shall not be excused or otherwise modified, as a result of the operation of this Section 2.21. The rights and remedies against a Defaulting Lender under this Section 2.21 are in addition to any other rights and remedies that the Borrower, the Administrative Agent, any Issuing Bank or any Lender might have against such Defaulting Lender. The failure of any Lender to perform its obligations under this Agreement shall not excuse or relieve any other Lender or any Issuing Bank of its obligations under this Agreement, and no Lender or Issuing Bank shall be responsible for the default of any other Lender or Issuing Bank except to the extent expressly provided herein.

If the Borrower, the Administrative Agent and each Issuing Bank agree in writing, in their reasonable determination, that a Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the other parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to cash collateral), that Lender will purchase such portion of outstanding Loans of the other Lenders and/or participations of the other Lenders in outstanding Letters of Credit, and

take such other actions, as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held on a pro rata basis by the Lenders in accordance with their Pro Rata Shares (without giving effect to Section 2.21(a)), whereupon such Lender will cease to be a Defaulting Lender; provided, however, that (i) no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender, and (ii) subject to Section 10.19 and except to the extent expressly agreed otherwise by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender.

Notwithstanding anything to the contrary contained in this Agreement, any payment of principal, interest, Facility Fees (with respect to the used portion of a Defaulting Lender’s Commitment), LC Participation Fees or other amounts received by the Administrative Agent for the account of any Defaulting Lender under this Agreement (whether voluntary or mandatory, at maturity, pursuant to Article VII or otherwise) shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any Issuing Banks hereunder; third, if so determined by the Administrative Agent or requested by any Issuing Bank, to be held as cash collateral for future funding obligations of such Defaulting Lender in respect of any participation in any Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held as cash collateral and released in order to satisfy obligations of such Defaulting Lender to fund Loans under this Agreement; sixth, to the payment of any amount owing to any Lender or Issuing Bank as a result of any judgment of a court of competent jurisdiction obtained by such Lender or Issuing Bank against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided, however, that if (i) any such payment is a payment of the principal amount of any Loan in respect of which such Defaulting Lender has not fully funded its appropriate share, and (ii) such Loan was made or the related Letter of Credit was issued at a time when the applicable conditions set forth in Article IV were satisfied or waived, then such payment shall be applied solely to repay the Loans of all non-Defaulting Lenders on a pro rata basis prior to being applied to the repayment of any Loan or portion thereof of such Defaulting Lender; and furtherprovided, however, that any amounts held as cash collateral for funding obligations of a Defaulting Lender shall be returned to such Defaulting Lender upon the termination of this Agreement and the satisfaction of such Defaulting Lender’s obligations hereunder. Any payments,

prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this Section 2.21 shall be deemed to have been paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents thereto.

Upon any Lender becoming a Defaulting Lender, the Borrower may remove and replace such Lender in accordance with Section 9.08.

a Reportable Event or Reportable Events, or a failure to make a required installment or other payment (within the meaning of Section 430(k)(1) of the Code), shall have occurred with respect to any Plan or Plans that reasonably could be expected to result in liability of the Borrower to the PBGC or to any Plan or Plans in an aggregate amount exceeding $25,000,000, or the value of the assets of any Plan is less than 80% of the “funding target” (as defined in Code Section 430(d)(1)) of such Plan as of the last annual valuation date applicable thereto, and within 30 days after the reporting of any such Reportable Event to the Administrative Agent or after the receipt by the Administrative Agent of a statement required pursuant to Section 5.06, the Administrative Agent shall have notified the Borrower in writing that (i) the Required Lenders have made a determination that, on the basis of such Reportable Event or Reportable Events, such failure to make a required installment or other payment or the fact that the value of the assets of a Plan is less than 80% of the “funding target” (as defined in Code Section 430(d)(1)) of such Plan as of the last annual valuation date applicable thereto, there are reasonable grounds (A) for the termination of any such Plan by the PBGC, (B) for the appointment by the appropriate United States District Court of a trustee to administer any such Plan or (C) for the imposition of a Lien in favor of any such Plan, and (ii) as a result thereof an Event of Default exists hereunder; or a trustee shall be appointed by a United States District Court to administer any such Plan; or the PBGC shall institute proceedings to terminate any such Plan;

any Loan Document, at any time after its execution and delivery and for any reason, shall cease to be in full force and effect, or is declared by a court of competent jurisdiction to be null and void, invalid or unenforceable in any respect, or the Borrower denies that it has any or further liability or obligation under any Loan Document, or purports to revoke, terminate or rescind any Loan

Document; provided, however, that the foregoing shall not apply to the First Mortgage Bond, the First Mortgage, the Supplemental Indenture or the Bond Delivery Agreement at any time when the Borrower’s obligations under this Agreement are not secured by the First Mortgage pursuant to the Borrower’s exercise of its rights under Section 8.01;

a Change in Control shall occur

except at any time when the Borrower’s obligations under this Agreement are not secured by the First Mortgage pursuant to the Borrower’s exercise of its rights under Section 8.01, the Lien purported to be created in any substantial portion of the property of the Borrower purported to be made subject thereto pursuantto the First Mortgage shall at any time fail to be a valid, perfected, first-priority Lien (subject to Liens permitted to exist by the terms of the First Mortgage) securing the obligations of the Borrower under the First Mortgage (including the obligations of the First Mortgage Bond), and such failure shall constitute or have resulted in a “Completed Default” under the First Mortgage; or

THE ADMINISTRATIVE AGENT

Section 9.01 Appointment and Powers. In order to expedite the various transactions contemplated by the Loan Documents, MUFG is hereby appointed to act as Administrative Agent on behalf of the Lenders and the Issuing Banks. Each of the Lenders and the Issuing Banks hereby irrevocably authorizes and directs the Administrative Agent to take such action on behalf of such Lender or Issuing Bank under the terms and provisions of the Loan Documents, and to exercise such powers thereunder as are specifically delegated to or required of the Administrative Agent by the terms and provisions thereof, together with such actions and powers as are reasonably incidental thereto. The Administrative Agent is hereby expressly authorized on behalf of the Lenders and the Issuing Banks, without hereby limiting any implied authority, (a) to receive on behalf of each of the Lenders and the Issuing Banks any payment of principal of or interest on the Loans and LC Disbursements outstanding hereunder, any reimbursements of LC Disbursements and all other amounts accrued under the Loan Documents paid to the Administrative Agent, and to distribute to each Lender and Issuing Bank its proper share of all payments so received as soon as practicable; (b) to give notice promptly on behalf of each of the Lenders and the Issuing Banks to the Borrower of any Event of Default of which the Administrative Agent has actual knowledge acquired in connection with its agency hereunder; and (c) to distribute promptly to each Lender

and each Issuing Bank copies of all notices, agreements and other material as provided for in the Loan Documents as received by such Administrative Agent.

Section 9.02 Limitation on Liability; Reliance by Administrative Agent.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(i)

shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing;

(ii)

shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law; and

(iii)

shall not, except as expressly set forth herein and in the other Loan Documents, 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 Affiliates that is communicated to or obtained by the person serving as the 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 (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Article VII and Section 10.08), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default (as the case may be) is given to the Administrative Agent in writing by the Borrower or a Lender.

Neither the Administrative Agent nor any of its Related Parties shall be liable to any Lender or Issuing Bank as such for any action taken or omitted by any of them under the Loan Documents except for its, his or her own gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and nonappealable judgment). Neither the Administrative Agent nor any of its Related

Parties shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the due execution, validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

The Administrative Agent shall in all cases be fully protected in acting, or refraining from acting, in accordance with written instructions signed by the Required Lenders, and, except as otherwise specifically provided herein, such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders and the Issuing Banks. The Administrative Agent shall, in the absence of knowledge to the contrary, be entitled to rely on any paper or document believed by it in good faith to be genuine and correct and to have been signed or sent by the proper person or persons.

Neither the Administrative Agent nor any of its Related Parties shall have any responsibility to the Borrower on account of the failure or delay in performance or breach by any Lender or Issuing Bank of any of its obligations under the Loan Documents or to any Lender or Issuing Bank on account of the failure of or delay in performance or breach by any other Lender or Issuing Bank or the Borrower of any of their respective obligations thereunder or in connection therewith. The Administrative Agent may execute any of its duties under the Loan Documents by or through agents, sub-agents or attorneys selected by it using reasonable care and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The exculpatory provisions of this Article shall apply to any such agents, sub agents or attorneys and to the Related Parties of the Administrative Agent and any such agents, sub agents or attorneys. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents, sub-agents or attorneys selected and authorized to act by it with reasonable care unless the damage complained of directly results from an act or failure to act on the part of the Administrative Agent which constitutes gross negligence or willful misconduct (as determined by a court of competent jurisdiction in a final and nonappealable judgment). Delegation to an attorney for the Administrative Agent shall not release the Administrative Agent from its obligation to perform or cause to be performed the delegated duty. The Administrative Agent shall be entitled to advice of legal counsel selected by it with respect to all matters arising under the Loan Documents and shall not be liable for any action taken or suffered in good faith by it in accordance with the advice of such counsel.

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 (including any electronic message, Internet or

intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated 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 have been made by the proper person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan or issuance of any Letter of Credit that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan or issuance of such Letter of Credit, as the case may be. 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 provisions of this Article are solely for the benefit of the Administrative Agent, the Issuing Banks and the Lenders, and the Borrower shall not have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 9.03 Other Transactions with Borrower, Etc. The person serving as the Administrative Agent and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders or the Issuing Banks. The person serving as the Administrative Agent 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 the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the person serving as the Administrative Agent when acting in its individual capacity.

Section 9.04 Reimbursement; Indemnification. Each Lender agrees (a) to reimburse the Administrative Agent in the amount of such Lender’s Pro Rata Share of any expenses incurred for the benefit of the Lenders by the Administrative Agent, including reasonable counsel fees and compensation of agents and employees paid for services rendered on behalf of the Lenders, to the extent not reimbursed by the Borrower and (b) to indemnify and hold harmless the Administrative Agent and any of its Related Parties, on demand, in the amount of its Pro Rata Share, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against it in its capacity as the Administrative Agent or any of them in any way relating to or arising out of the Loan Documents or any action taken or omitted by it or any

of them under the Loan Documents, to the extent not reimbursed by the Borrower; provided, however, that no Lender shall be liable to the Administrative Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Administrative Agent or any of its Related Parties, as determined by a court of competent jurisdiction in a final and nonappealable judgment.

Section 9.05 Absence of Reliance. Each of the Lenders and the Issuing Banks acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender, any other Issuing Bank or any of their respective Related Parties 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 of the Lenders and the Issuing Banks also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Lender, any other Issuing Bank or any of their respective Related Parties, and based on such documents and information as it shall deem appropriate at the time, continue to make its own decisions in taking or not taking action under or based upon the Loan Documents, any related agreement or any document furnished thereunder. Each Lender represents and warrants that (i) the Loan Documents set forth the terms of a commercial lending facility and (ii) it is engaged in making, acquiring or holding commercial loans in the ordinary course and is entering into this Agreement as a Lender for the purpose of making, acquiring or holding commercial loans set forth herein as may be applicable to such Lender, and not for the purpose of purchasing, acquiring or holding any other type of financial instrument, and each Lender agrees not to assert a claim in contravention of the foregoing. Each Lender represents and warrants that it is sophisticated with respect to decisions to make, acquire and/or hold commercial loans, as may be applicable to such Lender, and either it, or the person exercising discretion in making its decision to make, acquire and/or hold such commercial loans, is experienced in making, acquiring or holding such commercial loans.

Section 9.06 Resignation of Administrative Agent.

The Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Banks and the Borrower and shall promptly give such notice in the event that the Administrative Agent becomes a Defaulting Lender. Upon receipt of any such notice of resignation, the Required Lenders may, with the consent of the Borrower (which consent shall not be unreasonably withheld and shall not be required during an Event of Default), appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Banks and after consultation with the Lenders, the Issuing Banks and the Borrower, appoint a successor Administrative Agent. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

With effect from the Resignation Effective Date (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (ii) except for any indemnity payments owed to the retiring Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and Issuing Bank directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other than any rights to indemnity payments owed to the retiring Administrative Agent), and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. 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 retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article IX and Section 10.05 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 the retiring Administrative Agent was acting as Administrative Agent.

Section 9.07 Syndication Agent and Co-Documentation Agents. Neither the Syndication Agent nor any Co-Documentation Agent shall have any rights, powers, obligations, liabilities, responsibilities or duties under the Loan Documents other than those applicable to all Lenders as such. Without limiting the foregoing, none of the persons identified as “Syndication Agent” or “Co-Documentation Agent” shall have or be deemed to have any fiduciary relationship with any Lender or Issuing Bank. Each of the Lenders and the Issuing Banks acknowledges that it has not relied, and will not rely, on any of the persons so identified in deciding to enter into this Agreement or in takingor not taking action hereunder.

Section 9.08 Removal of Lender.

If a Lender (i) is a Defaulting Lender or (ii) fails to give its consent to any amendment, waiver or action for which consent of all of the Lenders was required and to which the Required Lenders consented, such Lender shall, upon notice from the Borrower, execute and deliver to the Administrative Agent one or more Assignment and Assumptions assigning all of that Lender’s interests, rights and obligations under the Loan Documents to one or more Eligible Assignees designated by the Borrower, subject to (A) compliance with the provisions of Section 10.04, (B) payment in full of all principal, interest and fees owing to such Lender through the date of assignment (including any amounts payable pursuant to Section 2.14 but, in the case of a Defaulting Lender, excluding any amounts payable pursuant to Section 2.14(c) or (d)) and (C) delivery by such assignee(s) of such appropriate assurances and indemnities (which may include letters of credit) as such Lender may reasonably require with respect to its participation interests in any Letters of Credit then outstanding; provided, however, that the failure of any such Lender to execute and deliver to the

Administrative Agent such Assignment and Assumption(s) shall not render such assignment(s) invalid, and the Administrative Agent shall record such assignment(s) in the Register. Alternatively, the Borrower may reduce the total Commitments (and for this purpose the minimum amounts for Commitment reductions shall not apply) by an amount equal to that Lender’s Commitment and pay and provide to such Lender the amounts, assurances and indemnities described above and release such Lender from its Commitment; provided, however, that the Commitment of a Defaulting Lender may not be so reduced so long as any Default or Event of Default has occurred and is continuing. The Administrative Agent shall distribute an amended Schedule 2.01 (which shall thereafter be incorporated into this Agreement) to reflect any new Commitments and Pro Rata Shares.

In order to make all Lenders’ interests in any outstanding Loans and in any fees and other amounts due in respect of Letters of Credit ratable in accordance with any revised Pro Rata Shares after giving effect to the removal of any Lender, the Borrower shall pay or prepay, if necessary, on the effective date of such removal all outstanding Loans and fees and other amounts in respect of Letters of Credit and pay, to the extent applicable, any amounts due under Section 2.14. The Borrower may then borrow Loans from the Lenders in accordance with their revised Pro Rata Shares.

Section 9.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to the Borrower, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise.

to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other obligations and liabilities that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders, the Issuing Banks and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Issuing Banks and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders, the Issuing Banks and the Administrative Agent under Section 10.05) allowed in such judicial proceeding; and

to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender and Issuing Bank to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders and Issuing Banks, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements

and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 10.05.

Section 9.10 Erroneous Payments.

If the Administrative Agent notifies a Lender or an Issuing Bank, or any person who has received funds on behalf of a Lender or an Issuing Bank (any such Lender, Issuing Bank or other recipient, a “Payment Recipient”) that the Administrative Agent has determined in its sole discretion (whether or not after receipt of any notice under paragraph (b) below) that any funds received by such Payment Recipient from the Administrative Agent or any of its Affiliates were erroneously transmitted to, or otherwise erroneously or mistakenly received by, such Payment Recipient (whether or not known to such Lender, Issuing Bank or other Payment Recipient on its behalf) (any such funds, whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise, individually and collectively, an “Erroneous Payment”) and demands the return of such Erroneous Payment (or a portion thereof), such Erroneous Payment shall at all times remain the property of the Administrative Agent and shall be segregated by the Payment Recipient and held in trust for the benefit of the Administrative Agent, and such Lender or Issuing Bank shall (or, with respect to any Payment Recipient who received such funds on its behalf, shall cause such Payment Recipient to) promptly, but in no event later than two (2) Business Days thereafter, return to the Administrative Agent the amount of any such Erroneous Payment (or portion thereof) as to which such a demand was made, in same day funds (in the currency so received), together with interest thereon in respect of each day from and including the date such Erroneous Payment (or portion thereof) was received by such Payment Recipient to the date such amount is repaid to the Administrative Agent in same day funds 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 from time to time in effect. A notice of the Administrative Agent to any Payment Recipientunder this paragraph(a) shall be conclusive, absentmanifest error.

Without limiting paragraph (a) above, each Lender or Issuing Bank, or any person who has received funds on behalf of a Lender or an Issuing Bank, hereby further agrees that if it receives a payment, prepayment or repayment (whether received as a payment, prepayment or repayment of principal, interest, fees, distribution or otherwise) from the Administrative Agent (or any of its Affiliates) (x) that is in a different amount than, or on a different date from, that specified in a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates) with respect to such payment, prepayment or repayment, (y) that was not preceded or accompanied by a notice of payment, prepayment or repayment sent by the Administrative Agent (or any of its Affiliates), or (z) that such Lender or Issuing Bank, or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case:

(i)

(A) in the case of clause (x) or clause (y) above, an error shall be presumed to have been made (absent written confirmation from the Administrative Agent to the contrary) or (B) an error has been made (in the case of clause (z) above), in each case, with respect to such payment, prepayment or repayment; and

(ii)

such Lender or Issuing Bank shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one (1) Business Day of its knowledge of such error) notify the Administrative Agent of its receipt of such payment, prepayment or repayment, the details thereof (in reasonable detail) and that it is so notifying the Administrative Agent pursuant to this Section 9.10(b).

Each Lender and Issuing Bank hereby authorizes the Administrative Agent to set off, net and apply any and all amounts at any time owing to such Lender or Issuing Bank under any Loan Document against any amount due to the Administrative Agent under paragraph (a) above or under the indemnification provisions of this Agreement.

In the event that an Erroneous Payment (or portion thereof) is not recovered by the Administrative Agent for any reason, after demand therefor by the Administrative Agent in accordance with paragraph (a) above, from any Lender or Issuing Bank that has received such Erroneous Payment (or portion thereof) (and/or from any Payment Recipient who received such Erroneous Payment (or portion thereof) on its respective behalf) (such unrecovered amount, an “Erroneous Payment Return Deficiency”), upon the Administrative Agent’s notice to such Lender or Issuing Bank at any time, (i) such Lender or Issuing Bank shall be deemed to have assigned its Loans (but not its Commitments) or LC Disbursements (as applicable) to the Administrative Agent in an amount equal to the Erroneous Payment Return Deficiency (or such lesser amount as the Administrative Agent may specify) (such assignment of the Loans (but not Commitments) or LC Disbursements, the “Erroneous Payment Deficiency Assignment”) at par plus any accrued and unpaid interest (with the assignment fee to be waived by the Administrative Agent in such instance), and is hereby (together with the Borrower) deemed to execute and deliver an Assignment and Assumption with respect to such Erroneous Payment Deficiency Assignment, and such Lender or Issuing Bank shall deliver any Notes evidencing such Loans to the Administrative Agent, (ii) the Administrative Agent as the assignee Lender shall be deemed to acquire the Erroneous Payment Deficiency Assignment, (iii) upon such deemed acquisition, the Administrative Agent as the assignee Lender shall become a Lender or Issuing Bank, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender or assigning Issuing Bank shall cease to be a Lender or Issuing Bank, as applicable, hereunder with respect to such Erroneous Payment Deficiency Assignment, excluding, for the avoidance of doubt, its obligations under the indemnification provisions of this Agreement and its applicable Commitments which shall survive as to such assigning Lender or assigning Issuing Bank and (iv) the Administrative Agent may reflect in the Register its ownership interest in the Loans and LC Disbursements subject to the ErroneousPayment

Deficiency Assignment. The Administrative Agent may, in its discretion, sell any Loans or LC Disbursements acquired pursuant to an Erroneous Payment Deficiency Assignment and upon receipt of the proceeds of such sale, the Erroneous Payment Return Deficiency owing by the applicable Lender or Issuing Bank shall be reduced by the net proceeds of the sale of such Loans or LC Disbursements (or portion thereof), and the Administrative Agent shall retain all other rights, remedies and claims against such Lender or Issuing Bank (and/or against any recipient that receives funds on its respective behalf). For the avoidance of doubt, no Erroneous Payment Deficiency Assignment will reduce the Commitments of any Lender or Issuing Bank and such Commitments shall remain available in accordance with the terms of this Agreement. In addition, each party hereto agrees that, except to the extent that the Administrative Agent has sold a Loan or LC Disbursement (or portion thereof) acquired pursuant to an Erroneous Payment Deficiency Assignment, and irrespective of whether the Administrative Agent may be equitably subrogated, the Administrative Agent shall be contractually subrogated to all the rights and interests of the applicable Lender or Issuing Bank under the Loan Documents with respect to each Erroneous Payment ReturnDeficiency.

The parties hereto agree that an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any obligations owed by the Borrower, except, in each case, to the extent such Erroneous Payment is, and solely with respect to the amount of such Erroneous Payment that is, comprised of funds received by the Administrative Agent from the Borrower for the purpose of making such Erroneous Payment.

To the extent permitted by applicable law, no Payment Recipient shall assert any right or claim to an Erroneous Payment, and hereby waives, and is deemed to waive, any claim, counterclaim, defense or right of set-off or recoupment with respect to any demand, claim or counterclaim by the Administrative Agent for the return of any Erroneous Payment received, including without limitation waiver of any defense based on “discharge for value” or any similardoctrine.

Each party’s obligations, agreements and waivers under this Section 9.10 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender or an Issuing Bank, the termination of the Commitments and/or the repayment, satisfaction or discharge of all obligations (or any portion thereof) of the Borrower under any Loan Document.

This Agreement shall become effective when it shall have been executed by the Borrower and the Administrative Agent and when the Administrative Agent shall have received copies hereof which, when taken together, bear the signatures of each Lender and each Issuing Bank, and this Agreement shall thereafter be binding upon and inure to the benefit of the Borrower, the Administrative Agent, each Lender and each Issuing Bank and their respective successors and permitted assigns.

Section 10.04 Successors and Assigns.

Subject to Section 6.03, the Borrower may not assign or delegate any of its rights or duties under any of the Loan Documents without the prior written consent of each of the Lenders and the Issuing Banks.

Each Lender (including the Administrative Agent and any Issuing Bank when acting as a Lender) may assign to one or more Eligible Assignees all or a portion of its interests, rights and obligations under the Loan Documents (including all or a portion of its Commitment and the same portion of the applicable Loan or Loans at the time owing to it); provided, however, that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, the Borrower and the Administrative Agent must give their prior written consent to such assignment (which consents shall not be unreasonably withheld, delayed or conditioned), providedthat (A) the Borrower shall be deemed to have consented to any such assignment unless it shall have objected thereto by written notice to the Administrative Agent within ten (10) Business Days after having received notice thereof and (B) the consent of the Borrower shall not be required if an Event of Default shall exist, (ii) in the case of an assignment to a person other than a Lender of all or a portion of a Lender’s Commitment or its obligation in

respect of its LC Exposure, the Issuing Banks must give their prior written consent to such assignment (which consents shall not be unreasonably withheld), (iii) no assignee of any Lender shall be entitled to receive any greater payment or protection under Section 2.12, 2.13(a) or 2.18 than such Lender would have been entitled to receive with respect to the rights assigned or otherwise transferred unless such assignment or transfer shall have been made at a time when the circumstances giving rise to such greater payment did not exist, (iv) each such assignment shall be of a constant, and not a varying, percentage of all the assigning Lender’s rights and obligations under this Agreement, (v) 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 not be less than $5,000,000 (or, if less, the total amount of such Lender’s Commitment), (vi) the parties to each such assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption and a processing and recordation fee of $3,500 and (vii) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. Upon acceptance and recording pursuant to paragraph (d) of this Section 10.04, from and after the effective date specified in each Assignment and Assumption, which effective date shall be at least five Business Days after the execution thereof, (A) 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 the Loan Documents and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under the Loan Documents (and, in the case of an Assignment and Assumption covering all or the remaining portion of an assigning Lender’s rights and obligations under the Loan Documents, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.12, 2.14, 2.18 and 10.05, as well as to any Fees accrued for its account and not yet paid).

The Administrative Agent shall maintain a copy of each Assignment and Assumption delivered to it, including the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The Administrative Agent, the Lenders and the Issuing Banks may treat each person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of the Loan Documents. The Register shall be available for inspection by the Borrower, any Lender and any Issuing Bank at any reasonable time and from time to time upon reasonable prior notice.

Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Eligible Assignee, an Administrative Questionnaire completed in respect of the Eligible Assignee (unless the Eligible Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) above and, to the extent required, the written consent of the Borrower, the Administrative Agent and the Issuing Banks to such assignment, the Administrative Agent shall (i) accept such Assignment and Assumption, (ii) record the

information contained therein in the Register and (iii) give prompt notice thereof to the Borrower and the Issuing Banks. Upon the request of the assignee, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent, a new Note or Notes to the order of such assignee in a principal amount equal to the applicable Commitment assumed by it pursuant to such Assignment and Assumption and, if the assigning Lender has retained a Commitment, upon the request of the assigning Lender, the Borrower shall execute and deliver a new Note to the order of such assigning Lender in a principal amount equal to the applicable Commitment retained by it. Canceled Notes shall be returned to the Borrower.

Each Lender may, without the consent of the Borrower, the Administrative Agent or any Issuing Bank, sell participations to one or more banks or other entities in all or a portion of its rights and obligations under the Loan Documents (including all or a portion of its Commitment and the Loans owing to it and any Notes held by it); provided, however, that (i) such Lender’s obligations under the Loan Documents shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other entities shall be entitled to the benefit of the cost protection provisions contained in Sections 2.12, 2.14 and 2.18 to the same extent as if they were Lenders (provided, that the amount of such benefit shall be limited to the amount in respect of the interest sold to which the seller of such participation would have been entitled had it not sold such interest) and (iv) the Borrower, the Administrative Agent, the other Lenders and the Issuing Banks shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to the Loans and to approve any amendment, modification or waiver of any provision of the Loan Documents (other than amendments, modifications or waivers (A) decreasing any Fees or the amount of principal of or the rate at which interest is payable on any Loans or LC Disbursements, (B) extending any scheduled date for the payment of Fees or principal of or interest on any Loans or LC Disbursements, (C) extending the expiration date of the Commitments, (D) extending the expiration date of any Letter of Credit to a date after the expiration date of the Commitments or (E) releasing the First Mortgage Bond or releasing all or substantially all of the collateral therefor, in each such case except pursuant to Article VIII).

Any Lender or participant may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 10.04, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure of information designated by the Borrower as confidential, each such assignee or participant or proposed assignee or participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of such confidential information.

Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special-purpose funding vehicle (an “SPC”) the option to

fund all or any part of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to fund all or any part of such Loan, the Granting Lender shall be obligated to fund such Loan pursuant to the terms hereof. The funding of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent as if such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or payment under the Loan Documents for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. Notwithstanding anything to the contrary contained in this Agreement, any SPC may disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee to such SPC. This paragraph may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loans are being funded by an SPC at the time of such amendment.

Any Lender may at any time assign for security purposes all or any portion of its rights under the Loan Documents to a Federal Reserve Bank; provided that no such assignment shall release a Lender from any of its obligations thereunder.

Section 10.05 Expenses; Indemnity, Damage Waiver.

The Borrower agrees to pay all reasonable out-of-pocket expenses (including the reasonable fees, chargesand disbursements of internal or external legal counsel) (i) incurred by the Administrative Agent in connection with the preparation of the Loan Documents, in connection with any amendments, modifications or waivers of the provisions thereof (whether or not the transactions thereby contemplated shall be consummated) or in connection with the use of DXSyndicate, IntraLinks or any similar service in relation to this Agreement, (ii) incurred by any Issuing Bank in connection with the issuance, renewal, extension or other amendment of any Letter of Credit or any demand for payment thereunder or (iii) incurred by the Administrative Agent, any Lender or any Issuing Bank in connection with the enforcement or protection of its rights in connection with any Loan Document, any Loan or any Letter of Credit or participation therein.

The Borrower agrees that it shall indemnify the Administrative Agent, the Lenders and the Issuing Banks against, and hold them harmless from, any documentary taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of this Agreement or any of the other Loan Documents.

The Borrower agrees to indemnify the Administrative Agent, each Lender and each Issuing Bank and each of their respective directors, officers, employees and agents (each such person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses,

including reasonable counsel fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of, (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument contemplated thereby, the performance by the parties thereto of their respective obligations thereunder or the consummation of the Transactions and the other transactions contemplated thereby, (ii) the use of the proceeds of the Loans and of the Letters of Credit (including any refusal by an Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictlycomply with the terms of such Letter of Credit) or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not 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 from the gross negligence or willful misconduct of such Indemnitee.

To the fullest 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, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof.

The provisions of this Section 10.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of the Administrative Agent, any Lender or any Issuing Bank. All amounts due under this Section 10.05 shall be payable on written demand therefor.

Section 10.06 Right of Setoff. If an Event of Default shall have occurred and be continuing and the Loans shall have been accelerated as set forth in Article VII, each of the Lenders and the Issuing Banks 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 indebtedness at any time owing by such Lender or Issuing Bank (or person Controlling such Lender or Issuing Bank) 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 and other Loan Documents held by such Lender or Issuing Bank, irrespective of whether or not such Lender or Issuing Bank shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower are owed to a branch or office of such Lender or Issuing Bank different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender and each Issuing Bank under this Section are in addition to other rights and remedies (including other rights of setoff) which such

Lender or Issuing Bank may have. Any Lender or Issuing Bank, as the case may be, shall promptly notify the Borrower after exercising its rights under this Section.

Section 10.07 Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, OTHER THAN THE FIRST MORTGAGE BOND, THE FIRST MORTGAGE AND THE SUPPLEMENTAL INDENTURE, SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

Section 10.08 Waivers; Amendment.

No failure or delay of the Administrative Agent, any Lender or any Issuing Bank in exercising any power or right under the Loan Documents 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, the Lenders and the Issuing Banks hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies which they would otherwise have. No waiver of any provision of this Agreement or any other 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) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

Except as otherwise expressly set forth in this Agreement (including Section 2.07(f) and Section 10.20), neither any Loan Document nor any provision thereof (excluding letter of credit applications, which may be waived, amended or otherwise modified by agreement of the Borrower and the applicable Issuing Bank) may be waived, amended or otherwise modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders; provided, however, that no such agreement shall (i) without the consent of the applicable Lender, (A) decrease the principal of or the rate of interest on such Lender’s Loans or the Fees payable to such Lender, (B) extend the date for any scheduled payment of principal of or interest on such Lender’s Loans or the Fees payable to such Lender, or (C) increasethe amount or extend the expiration date of such Lender’s Commitment, or (ii) without the consent of each Lender, (A) decrease the principal of or the rate of interest on any LC Disbursement, (B) extend the date for any scheduled payment of principal of or interest on any LC Disbursement, (C) extend the expiration date of any Letter of Credit after the Expiration Date has occurred, (D) release the First Mortgage Bond or release all or substantially all of the collateral therefor, in each such case except pursuant to Article VIII, or (E) amend or modify the provisions of Section 2.15, the provisions of this Section, the definition of “Required Lenders” or any other provision requiring the consent or agreement of each of the Lenders; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or any Issuing Bank under the Loan Documents without the prior written

consent of the Administrative Agent or such Issuing Bank, as the case may be. Each Lender and each holder of a Note shall be bound by any waiver, amendment or modification authorized by this Section regardless of whether its Note shall have been marked to make reference thereto, and any consent by any Lender or holder of a Note pursuant to this Section shall bind any person subsequently acquiring a Note from it, whether or not such Note shall have been so marked.

Section 10.09 Interest Rate Limitation. Notwithstanding anything herein or in any Notes to the contrary, if at any time the applicable interest rate, together with all fees and charges which are treated as interest under applicable law (collectively the “Charges”), as provided for herein or in any other document executed in connection herewith, or otherwise contracted for, charged, received, taken or reserved by any Lender, shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by such Lender in accordance with applicable law, the rate of interest payable under any Note held by such Lender, together with all Charges payable to such Lender, shall be limited to the Maximum Rate.

Section 10.10 Entire Agreement. Each Loan Document constitutes the entire contract between or among the parties relative to the subject matter thereof, and any previous agreement between or among the parties with respect to the subject matter thereof is superseded by such Loan Document. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any party other than the parties hereto and thereto any rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents.

Section 10.11 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 respect of any litigation directly or indirectly arising out of, under or in connection with this Agreement or any of the other Loan Documents. 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 and the other Loan Documents, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.11.

Section 10.12 Severability. In the event any one or more of the provisions contained in this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The parties 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 unenforceableprovisions.

Section 10.13 Counterparts; Electronic Execution. This Agreement may be executed in two or more counterparts, each of which shall constitute an original but all of which when taken together shall constitute but one contract, and shall become effective as provided in Section 10.13. Delivery of an executed counterpart of this Agreement by facsimile or other electronic transmission shall be effective as an original executed counterpart and shall be deemed a representation that the original executed counterpart will be delivered. The words “execution,” “executed,” “signed,” “signature,” “delivery,” and words of like import in or relating to any

document to be signed in connection with this Agreement, the other Loan Documents (including any Assignment and Assumption) and the transactions contemplated hereby shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; provided, that nothing herein shall require the Administrative Agent to accept electronic signatures in any form or format without its prior written consent; provided, further, that, without limiting the foregoing, upon the request of the Administrative Agent, any electronic signature shall be promptly followed by such manually executed counterpart.

Section 10.14 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 are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

Section 10.15 Jurisdiction; Consent to Service of Process.

The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, 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 shall affect any right that the Administrative Agent, any Lender or any Issuing Bank may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrower or its properties in the courts of any jurisdiction.

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 the other Loan Documents in any New York State or Federal court. 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 actionor proceeding in any such court.

Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 10.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

Section 10.16 USA Patriot Act Notification. Each Lender and each Issuing Bank hereby notifies the Borrower that, pursuant to the requirements of 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 Issuing Bank to identify the Borrower in accordance with the PATRIOT Act. The Borrower agrees to cooperate with each Lender and each Issuing Bank and to provide true, accurate and complete information to such Lenderor Issuing Bank in responseto any such request.

Section 10.17 Acknowledgment Regarding any Supported QFCs. To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Swap Contracts or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and each such QFC, a “Supported QFC”), the parties hereto acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation (or any successor thereto) under the Federal Deposit Insurance Act, as amended, and Title II of the Dodd-Frank Act, as amended (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”), in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States):

In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties hereto with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

As used in this Section 10.17, the following terms have the following meanings:

“BHC Act Affiliate” of a party shall mean an “affiliate” (as such term is defined under, and interpreted in accordance with, 12 U.S.C. 1841(k), as amended) of such party.

“Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable and as amended.

“QFC” has the meaning assigned to the term “qualified financial contract” in, and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D), as amended.
