Each such notice of a Borrowing (a “Notice of Borrowing”) shall be by telephone, confirmed immediately in writing or facsimile in substantially the form of Exhibit A hereto, specifying therein the requested (i) Borrowing Date for such Borrowing, (ii) Type of Loans comprising such Borrowing, (iii) aggregate amount of such Borrowing, and (iv) in the case of a Borrowing consisting of Term SOFR Loans, the initial Interest Period for each such Loan. Each Lender shall, before 2:00 P.M. (New York City Time) (or, for Borrowings consisting of Base Rate Loans for which notice was provided to the Lenders after 12:00 noon (New York City Time) but no later than 1:00 P.M.

After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower no later than 3:30 P.M. (New York City Time) in such manner as the Borrower shall have specified in the applicable Notice of Borrowing.

(b)Anything in subsection (a) above to the contrary notwithstanding, (i) the Borrower may not select Term SOFR Loans for any Borrowing if the aggregate amount of such Borrowing is less than

$1,000,000 or if the obligation of the Lenders to make Term SOFR Loans shall then be suspended pursuant to Section 2.12(b), 2.13 or 2.16, and (ii) there shall be not more than 6 separate Term SOFR Loans at any one time outstanding.

(c)Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to comprise Term SOFR Loans, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Loan to be made by such Lender as part of such Borrowing when such Loan, as a result of such failure, is not made on such date.

(d)Unless the Administrative Agent shall have received written notice from a Lender prior to any Borrowing Date or, in the case of a Base Rate Loan, prior to the time of Borrowing, that such Lender will not make available to the Administrative Agent such Lender’s Loan as part of the Borrowing to be made on such Borrowing Date, the Administrative Agent may, but shall not be required to, assume that such Lender has made such portion available to the Administrative Agent on such Borrowing Date in accordance with subsection (a) of this Section 2.02, and the Administrative Agent may (but it shall not be required to), 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 so made such Loan 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 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 so repaid shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement.

24

(e)The failure of any Lender to make the Loan to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Loan on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing.

Each Designated Lender shall notify the Administrative Agent by the date specified by the Administrative Agent (which date shall be a Business Day) that either (A) such Designated Lender declines to accept its additional Commitments or (B) such Designated Lender consents to accept the offered Commitments. Any Designated Lender not responding on or prior to the date specified by the Administrative Agent shall be deemed to have declined to accept the offered Commitments. The Administrative Agent shall, after receiving the notifications from all of the Designated Lenders or following the date specified in the notice to such Designated Lenders, whichever is earlier, notify the Borrower and the Lenders of the results thereof and the effective date of any additional Commitments. The effectiveness of such additional Commitments shall be subject to the conditions precedent that (i) unless the Collateral Release has occurred, the Borrower shall have issued to the Administrative Agent General and Refunding Mortgage Bonds, in form and substance similar to the General and Refunding Mortgage Bond issued to the Administrative Agent on the Closing Date, in accordance with the terms of the General and Refunding Mortgage Indenture, in an aggregate principal amount equal to the difference between the principal amount of the Commitments (after giving effect to such increase and any prior increases or permanent reductions to the Commitments) and the outstanding principal amount of General and Refunding Mortgage Bonds previously issued to the Administrative Agent as collateral support for the Obligations; and (ii) the Borrower shall have delivered to the Administrative Agent (A) the resolutions of the Borrower authorizing such additional Commitments (and, if applicable, such new issuance of General and Refunding Mortgage Bonds) and all Governmental Approvals (if any) required in connection with such additional Commitments (and, if applicable, such new issuance of General and Refunding Mortgage Bonds), certified as being in effect as of the effective date of such additional Commitments, (B) a favorable opinion of counsel for the Borrower as to such matters as any Lender through the Administrative Agent may reasonably request (including, if applicable, as to such new issuance of General and Refunding Mortgage Bonds) and (C) a certificate signed by a duly authorized officer of the Borrower, dated as of the effective date of such additional Commitments, stating that all conditions precedent to an Extension of Credit have been satisfied on and as of such effective date.

(d)The Loans made in respect of any Commitment increase pursuant to this Section 2.07 will rank pari passu in right of payment and security with the other Loans made hereunder and shall constitute and be part of the “Obligations” arising under this Agreement.

(e)Any increase in commitments pursuant to this Section 2.07 shall be established pursuant to amendment documentation as reasonably deemed necessary by the Administrative Agent, the Borrower and the applicable Designated Lender to incorporate the terms of such increased Commitments. Such commitments may be established as a new tranche of commitments with their own availability period for drawing and maturity date; provided that (i) any such maturity date must be no earlier than the Maturity Date, (ii) any such commitments shall be subject to no amortization prior to its maturity date and (iii) the other terms and conditions applicable to any such commitments shall be substantially the same as those applicable to the Commitments.

$5,000,000 in excess thereof. Each such notice of termination or reduction shall be irrevocable; provided, however, that a notice of termination delivered pursuant to this Section 2.08 may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the effective date specified in the notice of termination) if such condition is not satisfied.

(b)The Borrower may terminate the unused amount of the Commitment of any Lender that is a Defaulting Lender upon not less than three Business Days’ prior notice to the Administrative Agent (which shall promptly notify the Lenders thereof), and in such event the provisions of Section 2.21(a)(ii) will apply to all amounts thereafter paid by the Borrower for the account of such Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity or other amounts); provided that (i) no Event of Default shall have occurred and be continuing, and (ii) such termination shall not be deemed to be a waiver or release of any claim the Borrower, the Administrative Agent or any Lender may have against such Defaulting Lender.

(c)The Commitment of each Lender shall automatically terminate on the Availability Termination Date.

(d)Once terminated or reduced, the Commitment or any portion thereof as so terminated or reduced may not be reinstated.

(d)Any Lender may request that any Loans made by it be evidenced by one or more promissory notes. In such event, the Borrower shall prepare, execute and deliver to such Lender one or more promissory notes payable to such Lender (or, if requested by such Lender, to such Lender and its assignees) and in a form reasonably satisfactory to the Administrative Agent.

SECTION 2.12. Availability of Types of Loans; Adequacy of Interest Rate; Benchmark Replacement.

(a)Availability of Term SOFR Loans. Notwithstanding anything to the contrary in this Agreement or any other Loan Document, but subject to Section 2.12(b):

27

(ii)the Administrative Agent is advised by the Required Lenders that the interest rate applicable to Term SOFR Loans for any requested Interest Period is not ascertainable or available (including, without limitation, because the applicable screen (or on any successor or substitute page on such screen) is unavailable) and such inability to ascertain or unavailability is not expected to be permanent, or does not adequately and fairly reflect the cost of making or maintaining Term SOFR Loans, then the Administrative Agent shall suspend the availability of Term SOFR Loans and require any affected Term SOFR Loans to be repaid or converted to Base Rate Loans, subject to the payment of any funding indemnification amounts required by Section 2.02.

Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Loans to be Converted, and (iii) if such Conversion is into Term SOFR Loans, the duration of the initial Interest Period for each such Loan. Each notice of Conversion shall be irrevocable and binding on the Borrower.

(b)Mandatory.

(i)If the Borrower shall fail to select the Type of any Loan or the duration of any Interest Period for any Borrowing comprising Term SOFR Loans in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and Section 2.13(a), or if any proposed Conversion of a Loan that is to comprise Term SOFR Loans upon Conversion shall not occur as a result of the circumstances described in subsection (c) below, or if an Event of Default has occurred and is continuing and Term SOFR Loans are outstanding, the Administrative Agent will forthwith so notify the Borrower and the Lenders, and (i) such Loans will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Loans and (ii) the obligation of the Lenders to make, or to Convert Loans into, Term SOFR Loans shall be suspended.

The Borrower’s obligations under this subsection (c) shall survive the repayment of all other amounts owing to the Lenders and the Administrative Agent under this Agreement and the termination of the Commitment.

(d)Limitation on Certain Conversions. Notwithstanding any other provision of this Agreement to the contrary, the Borrower may not borrow Loans at Term SOFR or Convert Loans resulting in Term SOFR Loans at any time an Event of Default has occurred and is continuing.

SECTION 2.14. Optional Prepayments of Loans.

The Borrower may prepay Loans, (i) upon at least two Business Days’ notice, in the case of Term SOFR Loans, and (ii) upon notice not later than 12:00 noon (New York City Time) on the date of prepayment, in the case of Base Rate Loans, to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and, if such notice is given, the Borrower shall prepay the outstanding principal amount of the Loans comprising part of the same Borrowing in whole or ratably in part, without penalty, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in an aggregate principal amount of $1,000,000 or an integral multiple of $100,000 in excess thereof and (y) in the event of any such prepayment of a Term SOFR Loan, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

SECTION 2.15. Increased Costs.

(a)Increased Costs Generally. If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, assessment, 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;

(ii)other than (A) Indemnified Taxes and (B) Excluded Taxes, subject any Recipient to any Taxes on, or change the basis of taxation of payments to any Recipient in respect of, 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 the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender;

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 or maintaining any Loan or of maintaining its obligation to make any such Loan or to reduce the amount of any sum received or receivable by such Lender or other Recipient hereunder (whether of principal, interest or any other amount) then, upon the good faith request of such Lender or other Recipient, the Borrower will pay to such Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

30

(b)Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any lending office of such Lender or such Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitment of the Initial Lender or the Loans made by such Lender to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c)Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as specified in subsection (a) or

(b) of this Section and delivered to the Borrower, shall be conclusive absent manifest error.    The Borrower shall pay such Lender promptly upon demand the amount shown as due on any such certificate.

(d)Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof).

SECTION 2.16. Illegality.

If any Lender determines that any Change in 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 the Term SOFR Rate, or to determine or charge interest rates based upon the Term SOFR Rate, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, upon notice thereof by such Lender to the Borrower (through the Administrative Agent), (a) any obligation of such Lender to make or continue Term SOFR Borrowings or to convert Base Rate Borrowings to Term SOFR Borrowings shall be suspended, and (b) if such notice asserts the illegality of such Lender making or maintaining Base Rate Borrowings the interest rate on which is determined by reference to the Term SOFR Rate component of the Base Rate, the interest rate on which Base Rate Loans of such Lender shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Term SOFR Rate component of the Base Rate, in each case until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such determination no longer exist. Upon receipt of such notice, (x) the Borrower shall, upon demand from such Lender (with a copy to the Administrative Agent), prepay or, if applicable, convert each Term SOFR Loan of such Lender to a Base Rate Loan (the interest rate on which Base Rate Loan shall, if necessary to avoid such illegality, be determined by the Administrative Agent without reference to the Term SOFR Rate component of the Base Rate), either on the last day of the Interest Period therefor, if such Lender can lawfully continue to maintain such Term SOFR Loan to such day, or immediately, if such Lender cannot lawfully continue to maintain such Term SOFR Loan, and (y) if such notice asserts the illegality of such Lender determining or charging interest rates based upon the Term SOFR Rate, the Administrative Agent shall during the period of such suspension compute the Base Rate applicable to such Lender without reference to the Term SOFR Rate component thereof until the Administrative Agent is advised in writing by such Lender that it is no longer illegal for such Lender to determine or charge interest rates based upon the Term SOFR Rate. Upon any such prepayment or conversion, the Borrower shall also pay accrued interest on the amount so prepaid or converted, together with any additional amounts required pursuant to Section 8.04.

31

SECTION 2.17. Payments and Computations.

(a)The Borrower shall make each payment to be made by it hereunder not later than 1:00

P.M. (New York City Time) on the day when due in Dollars to the Administrative Agent at the Agent’s Account in same day funds without condition or deduction for any counterclaim, defense, recoupment or setoff. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or commitment fees ratably (other than amounts payable pursuant to Section 2.02(c), 2.06, 2.11(c), 2.13(c), 2.15, 2.18, 2.21 or 8.04(c)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(c), from and after the effective date specified in such Assignment and Assumption, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b)The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder, after any applicable grace period, to charge from time to time against any or all of the Borrower’s accounts with such Lender any amount so due.

(c)All computations of interest based on the rate referred to in clause (i) of the definition of the “Base Rate” contained in Section 1.01 shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Term SOFR Rate, the Federal Funds Effective Rate, or the rate referred to in clause (iii) of the definition of the “Base Rate” and of commitment fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or commitment fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d)Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment fees, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Term SOFR Loans to be made in the next following calendar month or on a date after the Maturity Date, such payment shall be made on the next preceding Business Day. Notwithstanding anything to the contrary contained herein, if the Maturity Date shall occur on a date other than a Business Day, the Borrower shall repay to the Administrative Agent for the account of each Lender on the next preceding Business Day prior to the Maturity Date the aggregate principal amount of the Loans made to the Borrower by the Lenders then outstanding.

(e)Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to a Lender hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date, and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Effective Rate.

32

SECTION 2.18. Taxes.

(a)Defined Terms. For purposes of this Section 2.18 and for the avoidance of doubt, the term “Applicable Law” includes FATCA.

(b)Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c)Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d)Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 30 days after demand therefor, for any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so). Each Lender shall severally indemnify the Administrative Agent and the Borrower, within 30 days after demand therefor, for (i) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 8.07(d) relating to the maintenance of a Participant Register and (ii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent or the Borrower in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent or the Borrower shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent or the Borrower to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent or the Borrower to the Lender from any other source against any amount due to the Administrative Agent or the Borrower under this subsection (e).

(f)Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.18, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

33

(g)Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.18(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing,

(A)any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), an executed IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(i)in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, an executed IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, an executed IRS Form W-8BEN-E or IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii)an executed IRS Form W-8ECI;

(iii)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Internal Revenue Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y) an executed IRS Form W-8BEN-E or IRS Form W-8BEN; or

34

(iv)to the extent a Foreign Lender is not the beneficial owner, an executed IRS Form W-8IMY, accompanied by an executed IRS Form W-8ECI, IRS Form W- 8BEN-E or IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner;

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D)if a payment made to a Lender under any Loan Document would be subject to

U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender 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 Internal Revenue 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 has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it 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.

(h)Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.18 (including by the payment of additional amounts pursuant to this Section 2.18), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all reasonable out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this subsection (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this subsection (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this subsection (h) the payment of which would place the indemnified party in a less favorable net after- Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This subsection shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i)Survival. Each party’s obligations under this Section 2.18 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all Obligations.

35

SECTION 2.19. Sharing of Payments, Etc.

If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its Commitment Percentage thereof as provided herein, then the Lender receiving such greater proportion shall (i) notify the Administrative Agent of such fact, and (ii) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that:

(A)if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(B)the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender and any payment made pursuant to Section 2.02(c), 2.06, 2.11(c), 2.13(c), 2.15, 2.18, 2.21 or 8.04(c) or, in respect of Term SOFR Loans converted into Base Rate Loans, pursuant to Section 2.16), or

(y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this Section shall apply).

The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

SECTION 2.20. Mitigation Obligations; Replacement of Lenders.

(a)Designation of a Different Lending Office. If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different Applicable Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.18, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)Replacement of Lenders. If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18 and, in each case, such Lender has declined or is unable to designate a different Applicable Lending Office in accordance with subsection (a) above, or if any Lender is a Non-Consenting Lender or a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 8.07), all of its interests, rights (other than its existing rights to payments pursuant to Section 2.15 or Section 2.18) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if such Lender accepts such assignment); provided that:

(i)the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 8.07(b)(iv);

36

(ii)such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and, together with all applicable accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 8.04(c)) from the assignee (to the extent of such outstanding principal amounts and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii)in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.18, such assignment will result in a reduction in such compensation or payments thereafter;

(iv)such assignment shall not conflict with Applicable Law;

(v)in the case of any assignment resulting from a Lender becoming a Non- Consenting Lender, the applicable assignee shall have consented to the applicable extension, amendment, waiver or consent; and

(vi)No Default shall have occurred and be continuing.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.21. Defaulting Lenders.

(a)Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by Applicable Law:

(i)Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders and in Section 8.01.

(ii)Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article 6.01 or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 8.05 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, as the Borrower may request (so long as no Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; third, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement; fourth, to the payment of any amounts owing to the Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; fifth, so long as no 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 sixth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made at a time when the conditions set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of such Defaulting Lender until such time as all Loans are held by the Lenders pro rata in accordance with the Commitments. 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 pursuant to this Section 2.21(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

37

(iii)Certain Fees. No Defaulting Lender shall be entitled to receive any commitment fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(iv)Defaulting Lender Cure. If the Borrower and the Administrative Agent agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans to be held pro rata by the Lenders in accordance with the Commitments, whereupon such Lender will cease to be a Defaulting Lender; provided that 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 provided, further, that except to the extent otherwise expressly agreed in writing 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 that Lender’s having been a Defaulting Lender.

40

(d)The execution, delivery and performance by Borrower of the Loan Documents will not (i) violate (A) the articles of incorporation or bylaws (or comparable documents) of Borrower or any of its Material Subsidiaries or (B) any Applicable Law, (ii) be in conflict with, or result in a breach of or constitute a default under, any contract, agreement, indenture or instrument to which the Borrower or any of its Material Subsidiaries is a party or by which any of its or their respective properties is bound or (iii) result in the creation or imposition of any Lien on the property of Borrower or any of its Material Subsidiaries other than Permitted Liens and Liens required under this Agreement, except to the extent such conflict, breach or default referred to in the preceding clause (ii), individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect.

(f)The Borrower and each Material Subsidiary are in compliance with all Applicable Laws (including Environmental Laws), except to the extent that failure to comply would not reasonably be expected to have a Material Adverse Effect.

(g)There is no action, suit, proceeding, claim or dispute pending or, to the Borrower’s knowledge, threatened against or affecting the Borrower or any of its Material Subsidiaries, or any of its or their respective properties or assets, before any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. There is no injunction, writ, preliminary restraining order or any other order of any nature issued by any Governmental Authority directing that any material aspect of the transactions expressly provided for in any of the Loan Documents not be consummated as herein or therein provided.

(h)The consolidated balance sheet of the Borrower and its Consolidated Subsidiaries as at December 31, 2020, and the related consolidated statements of income, cash flows and stockholders’ equity for the fiscal year ended on such date, certified by Deloitte & Touche LLP, copies of which have heretofore been furnished to the Administrative Agent and each Lender, present fairly in all material respects the financial condition of the Borrower and its Consolidated Subsidiaries as at such date, and the consolidated results of their operations and cash flows for the fiscal year then ended. All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as may be disclosed therein).

No Hazardous Materials have been or are present or are being spilled, discharged or released on, in, under or from property (real, personal or mixed) currently or formerly owned, leased or operated by the Borrower or any Material Subsidiary in any quantity or manner violating, or resulting in liability under, any applicable Environmental Law, which violation or liability would reasonably be expected to have a Material Adverse Effect.

(o)No written statement or information furnished by or on behalf of the Borrower to the Administrative Agent or any Lender in connection with the syndication or negotiation of this Agreement or delivered pursuant hereto, in each case as of the date such statement or information is made or delivered, as applicable, contained or contains, any material misstatement of fact or intentionally omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were, are, or will be made, not misleading.

(p)Each Material Subsidiary as of the date hereof is set forth on Schedule II.

42

(r)At all times prior to the Collateral Release, the General and Refunding Mortgage Indenture is effective to create in favor of the Indenture Trustee, for the ratable benefit of all Holders of Securities (as defined in the General and Refunding Mortgage Indenture), a legal, valid, binding, subsisting and enforceable Lien on and security interest in the Mortgaged Property and the proceeds thereof, subject to applicable Debtor Relief Laws, and such Lien constitutes a fully perfected Lien on, and security interest in, all right title and interest of the grantors thereof in such Mortgaged Property and the proceeds thereof, in each case prior to and superior in right to any other Person subject only to Permitted Liens (as defined in the General and Refunding Mortgage Indenture).

(s)At all times prior to the Collateral Release, the General and Refunding Mortgage Bonds, when executed by the Borrower and authenticated by the Indenture Trustee in accordance with the General and Refunding Mortgage Indenture and delivered to the Administrative Agent in accordance with the terms hereof, will constitute valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their terms, except as the enforceability thereof may be limited by applicable Debtor Relief Laws.

ARTICLE VII

THE ADMINISTRATIVE AGENT

SECTION 7.01. Appointment and Authority.

Each Lender hereby irrevocably appoints U.S. Bank to act on its behalf as the Administrative Agent hereunder, under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Each Lender hereby authorizes the Administrative Agent to vote the General and Refunding Mortgage Bonds, or consent with respect thereto, at any meeting (or where the vote or consent of the bondholders is requested without a meeting) of the bondholders under the General and Refunding Mortgage Indenture. The provisions of this Article are solely for the benefit of the Administrative Agent, 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, in any other Loan Document 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 7.02. Rights as a Lender.

The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person 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.

SECTION 7.03. Exculpatory Provisions.

(a)The Administrative Agent shall not have any duties or obligations except those expressly set forth herein, 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 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, 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, 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 or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

50

(iii)shall not, except as expressly set forth herein, 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.

(b)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 Sections 6.01 and 8.01), 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 unless and until notice describing such Default is given to the Administrative Agent in writing by the Borrower or a Lender.

(c)The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, 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, (iv) the 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 III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

SECTION 7.04. Reliance by Administrative Agent.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (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, that by its terms must be fulfilled to the satisfaction of any 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. 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.

SECTION 7.05. Resignation of Administrative Agent.

(a)The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be (i) a commercial bank with an office in the United States having a combined capital and surplus of at least $500,000,000, or an Affiliate of any such bank with an office in the United States and (ii) subject to the approval of the Borrower so long as no Default shall have occurred and be continuing (such approval not to be unreasonably withheld or delayed). If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to), on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

51

(b)If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) if the definition thereof, the Required Lenders may, to the extent permitted by Applicable Law, by notice in writing to the Borrower and such Person remove such Person as Administrative Agent and, in consultation with the Borrower, appoint a successor, which shall be (i) a commercial bank with an office in the United States having a combined capital and surplus of at least $500,000,000, or an Affiliate of any such bank with an office in the United States and (ii) subject to the approval of the Borrower so long as no Default shall have occurred and be continuing (such approval not to be unreasonably withheld or delayed). If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Required Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c)With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (2) except for any indemnity payments owed to the retiring or removed 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 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 or removed Administrative Agent (other than any rights to indemnity payments owed to the retiring or removed Administrative Agent), and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder, 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 or removed Administrative Agent’s resignation or removal hereunder, under the other Loan Documents, the provisions of this Article and Section 8.04 shall continue in effect for the benefit of such retiring or removed 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 or removed Administrative Agent was acting as Administrative Agent.

(d)Notwithstanding anything in this Section 7.05 to the contrary, the retiring or removed Administrative Agent shall continue to hold any collateral as bailee for the benefit of the Lenders until a successor Administrative Agent has been appointed in accordance with this Section 7.05.

SECTION 7.06. Non-Reliance on Administrative Agent and Other Lenders.

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

52

SECTION 7.07. Indemnification.

Each Lender severally agrees to indemnify the Administrative Agent (to the extent not promptly reimbursed by the Borrower and without limiting its obligation to do so) from and against such Lender’s Commitment Percentage of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement, any other Loan Document or any action taken or omitted by the Administrative Agent under this Agreement, any other Loan Document; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct, as proven in a court of competent jurisdiction by final and nonappealable judgment. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its Commitment Percentage of any costs and expenses (including, without limitation, fees and reasonable expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Administrative Agent is not promptly reimbursed for such costs and expenses by the Borrower (and without limiting its obligation to do so) after request therefor. The failure of any Lender to reimburse the Administrative Agent promptly upon demand for its Commitment Percentage of any amount required to be paid by the Lender to the Administrative Agent as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Administrative Agent for its Commitment Percentage of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Administrative Agent for such other Lender’s Commitment Percentage of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 7.07 shall survive the payment in full of the Obligations.

SECTION 7.08. No Other Duties, etc.

Anything herein to the contrary notwithstanding, none of the Joint Lead Arrangers, the “Joint Bookrunners”, the “Syndication Agents” or Documentation Agents” listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement, any other Loan Document, except in its capacity, as applicable, as the Administrative Agent, a Lender hereunder or thereunder.

SECTION 7.09. Collateral Release Matters.

(a)Notwithstanding any provision herein to the contrary, after the occurrence of the Collateral Release Trigger, the Borrower may, by written notice to the Administrative Agent, elect to release the General and Refunding Mortgage Bonds, and the Administrative Agent will take any action reasonably requested by the Borrower to effect such release (the “Collateral Release”).

(b)Each Lender irrevocably authorizes the Administrative Agent, at its option and in its discretion, to release any Lien on any collateral granted to or held by the Administrative Agent under any Loan Document or to release the General and Refunding Mortgage Bonds (i) with notice to the Lenders, as permitted pursuant to Section 7.09(a), (ii) upon termination of the Commitments and payment in full of all Obligations under the Loan Documents (other than (A) contingent indemnification obligations as to which no claim has been asserted and (B) Obligations under Hedge Agreements and Treasury Management Agreements either (x) as to which arrangements satisfactory to the applicable parties to such agreements shall have been made or (y) notice has not been received by the Administrative Agent from such parties that amounts are due and payable under such Hedge Agreement or Treasury Management Agreement, as the case may be) or (iii) if approved, authorized or ratified in writing in accordance with Section 8.01.

(c)In each case as specified in clauses (i) through (iii) of Section 7.09(b), the Administrative Agent will take any action reasonably requested by the Borrower to effect such release in accordance with the terms of the Loan Documents and this Section.

53

(d)Upon request by the Administrative Agent at any time, each Lender will confirm in writing the Administrative Agent’s authority to release its interest in particular types or items of property pursuant to this Section.

SECTION 7.10. Erroneous Payments.

(a)If the Administrative Agent notifies a Lender or Credit Party, or any Person who has received funds on behalf of a Lender or Credit Party such Lender (any such Lender Credit Party 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 immediately succeeding clause (b)) 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, Credit Party 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 Credit Party 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 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 Recipient under this clause (a) shall be conclusive, absent manifest error.

(b)Without limiting immediately preceding clause (a), each Lender or Credit Party, or any Person who has received funds on behalf of a Lender or Credit Party such Lender, 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 Credit Party, or other such recipient, otherwise becomes aware was transmitted, or received, in error or by mistake (in whole or in part) in each case:

(c)(A) in the case of immediately preceding clauses (x) or (y), 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 immediately preceding clause (z)), in each case, with respect to such payment, prepayment or repayment; and

(d)such Lender or Credit Party shall (and shall cause any other recipient that receives funds on its respective behalf to) promptly (and, in all events, within one 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 7.10(b).

(e)Each Lender or Credit Party hereby authorizes the Administrative Agent to set off, net and apply any and all amounts at any time owing to such Lender or Credit Party under any Loan Document, or otherwise payable or distributable by the Administrative Agent to such Lender or Credit Party from any source, against any amount due to the Administrative Agent under immediately preceding clause (a) or under the indemnification provisions of this Agreement.

54

(f)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 immediately preceding clause (a), from any Lender 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 at any time, (i) such Lender shall be deemed to have assigned its Loans (but not its Commitments) of the relevant class with respect to which such Erroneous Payment was made (the “Erroneous Payment Impacted Class”) 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) of the Erroneous Payment Impacted Class, 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 (or, to the extent applicable, an agreement incorporating an Assignment and Assumption by reference pursuant to a Platform as to which the Administrative Agent and such parties are participants) with respect to such Erroneous Payment Deficiency Assignment, and such Lender shall deliver any Notes evidencing such Loans to the Borrower or 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 hereunder with respect to such Erroneous Payment Deficiency Assignment and the assigning Lender shall cease to be a Lender 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 and (iv) the Administrative Agent may reflect in the Register its ownership interest in the Loans subject to the Erroneous Payment Deficiency Assignment. The Administrative Agent may, in its discretion, sell any Loans 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 shall be reduced by the net proceeds of the sale of such Loan (or portion thereof), and the Administrative Agent shall retain all other rights, remedies and claims against such Lender (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 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 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 Credit Party under the Loan Documents with respect to each Erroneous Payment Return Deficiency (the “Erroneous Payment Subrogation Rights”).

(g)The parties hereto agree that an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any obligations owed by the Borrower or any other Loan Party, 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 or any other Loan Party for the purpose of making a payment or prepayment of the Obligations.

(h)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 similar doctrine

(i)Each party’s obligations, agreements and waivers under this Section 7.10 shall survive the resignation or replacement of the Administrative Agent, any transfer of rights or obligations by, or the replacement of, a Lender the termination of the Commitment and/or the repayment, satisfaction or discharge of all obligations (or any portion thereof) under any Loan Document.

No failure on the part of any Lender or the Administrative Agent to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 8.04. Costs and Expenses; Indemnification.

(a)The Borrower agrees to pay promptly upon demand (i) all reasonable out-of-pocket costs and expenses of the Administrative Agent, the Joint Lead Arrangers and its respective Affiliates in connection with the preparation, negotiation, execution, delivery, administration, modification and amendment of this Agreement and the other documents to be delivered hereunder, including, without limitation, (A) all due diligence, syndication (including printing, distribution and bank meetings), transportation, computer, duplication, appraisal, consultant, and audit expenses, (B) the reasonable fees and expenses of counsel for the Administrative Agent with respect thereto and with respect to advising the Administrative Agent as to its rights and responsibilities under this Agreement and (C) all out-of- pocket fees and expenses of the Administrative Agent and its Affiliates in connection with any action taken to effect the Collateral Release.

58

(b)The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender, the Joint Lead Arrangers and each Lender, and each Related Party of any of the foregoing Persons (each, an “Indemnified Party”) from and against any and all claims, damages, losses and liabilities, joint or several, to which any such Indemnified Party may become subject, in each case arising out of or in connection with or relating to (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Loans, and shall reimburse any Indemnified Party for any and all reasonable expenses (including, without limitation, reasonable fees and expenses of counsel) as they are incurred in connection with the investigation of or preparation for or defense of any pending or threatened claim or any action or proceeding arising therefrom, whether or not such Indemnified Party is a party (but if not a party thereto, then only with respect to such proceedings where such Indemnified Party (i) is subject to legal process or other compulsion of law, (ii) believes in good faith that it will be so subject, or (iii) believes in good faith that it is necessary or appropriate for it to resist any legal process or other compulsion of law which is purported to be asserted against it) and whether or not such claim, action or proceeding is initiated or brought by or on behalf of the Borrower or any of its Affiliates and whether or not any of the transactions contemplated hereby are consummated or this Agreement is terminated, except to the extent such claim, damage, loss, liability or expense is found in a judgment by a court of competent jurisdiction by final and nonappealable judgment to have resulted from such Indemnified Party’s gross negligence, bad faith or willful misconduct. In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by the Borrower, its directors, shareholders or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. The Borrower agrees not to assert any claim against the Administrative Agent, any Lender, any of their respective Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Loans. This Section 8.04(b) shall not apply with respect to Taxes that are Indemnified Taxes, Excluded Taxes or Taxes that are covered by Section 2.15(a)(ii).

(c)If any payment of principal of, or Conversion of, any Term SOFR Loan is made by the Borrower to or for the account of a Lender other than on the last day of the Interest Period for such Loan, as a result of a payment or Conversion pursuant to Section 2.09, 2.12(b), 2.13, 2.14, 2.15 or 2.16, acceleration of the maturity of the outstanding Loans pursuant to Section 6.01, assignment to another Lender upon demand of the Borrower pursuant to Section 2.20(b) or for any other reason (in the case of any such payment or Conversion), the Borrower shall, promptly upon demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion, including, without limitation, any loss (other than loss of Applicable Margin), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Loan.

(d)Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.15, 2.16, 2.19 and 8.04 shall survive the payment in full of the Obligations.

(e)The Borrower agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Borrower or its respective security holders or creditors related to or arising out of or in connection with this Agreement, the Loans or the use or proposed use of the proceeds thereof, any of the transactions contemplated by any of the foregoing or in the loan documentation and the performance by an Indemnified Party by any of the foregoing except to the extent that any loss, claim, damage, liability or expense is found in a judgment by a court of competent jurisdiction by final and nonappealable judgment to have resulted from such Indemnified Party’s gross negligence or willful misconduct.

59

(f)In the event that an Indemnified Party is requested or required to appear as a witness in any action brought by or on behalf of or against the Borrower or any of its Affiliates in which such Indemnified Party is not named as a defendant, the Borrower agrees to reimburse such Indemnified Party for all reasonable expenses incurred by it in connection with such Indemnified Party’s appearing and preparing to appear as such a witness, including, without limitation, the fees and disbursements of its legal counsel.

SECTION 8.05. Right of Set-off.

Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the outstanding Loans due and payable pursuant to the provisions of Section 6.01, each Lender and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by Applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held, and other obligations (in whatever currency) at any time owing, by such Lender or any such Affiliate, to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement or any other Loan Document to such Lender or its Affiliates, irrespective of whether or not such Lender or such Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of the Borrower may be contingent or unmatured or are owed to a branch, office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.21 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the obligations of the Borrower owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of each Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender or its Affiliates may have. Each Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

SECTION 8.06. Binding Effect.

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 been notified by each Lender that such Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of all of the Lenders.

SECTION 8.07. Assignments and Participations.

(a)Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent, and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of subsection (b) of this Section, (ii) by way of participation in accordance with the provisions of subsection (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of subsection (e) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in subsection (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

60

(b)Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i)Minimum Amounts.

(A)in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitments and/or the Loans at the time owing to it or contemporaneous assignments to related Approved Funds that equal at least the amount specified in subsection (b)(i)(B) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B)in any case not described in subsection (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans 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 or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, or an integral multiple of $1,000,000 in excess thereof, unless each of the Administrative Agent and, so long as no Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii)Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned.

(iii)Required Consents. No consent shall be required for any assignment except to the extent required by subsection (b)(i)(B) of this Section and, in addition:

(A)the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender or an Affiliate of a Lender; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within ten Business Days after having received written notice thereof; and

(B)the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments if such assignment is to a Person that is not a Lender with a Commitment or an Affiliate of such Lender; and

(iv)Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v)No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any of the Borrower’s Affiliates (except for any Affiliate of Berkshire Hathaway not controlled directly or indirectly by the Borrower that is a commercial lender acquiring rights and obligations under this Agreement in the ordinary course of its business) or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B).

(vi)No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

61

(vii)Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans in accordance with its Commitment Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under Applicable Law without compliance with the provisions of this subsection, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.15,

2.18and 8.04 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

(c)Register. The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d)Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower’s Affiliates (except for any Affiliate of Berkshire Hathaway not controlled directly or indirectly by the Borrower that is a commercial lender acquiring participations under this Agreement in the ordinary course of its business) or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 7.07 with respect to any payments made by such Lender to its Participant(s).

62

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 8.01 requiring the consent of each Lender directly affected thereby that directly affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.18 and 8.04(c) (subject to the requirements and limitations therein, including the requirements under Section 2.18(g) (it being understood that the documentation required under Section 2.18(g) shall be delivered to the participating Lender or the applicable Withholding Agent to the extent required by Applicable Law)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 2.20 as if it were an assignee under subsection (b) of this Section; and (B) shall not be entitled to receive any greater payment under Section 2.15 or 2.18, with respect to any participation, than its participating Lender would have been entitled to receive. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.20(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender; provided that such Participant agrees to be subject to Section

2.19as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations or to comply with other requirements under applicable tax law. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e)Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central banking authority; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 8.08. Confidentiality.

Neither the Administrative Agent nor any Lender shall disclose any Confidential Information to any other Person without the consent of the Borrower, other than (i) to the Administrative Agent’s or such Lender’s Affiliates and their officers, directors, employees, agents and advisors, to the Administrative Agent or a Lender and, as contemplated by Section 8.07, to actual or prospective assignees and participants, and then only on a confidential basis, (ii) as required by any law, rule or regulation or judicial process, (iii) to any rating agency when required by it, provided, that, prior to any such disclosure, such rating agency, commercial paper dealer or provider shall undertake to preserve the confidentiality of any Confidential Information received by it from such Lender, (iv) as requested or required by any state, federal or foreign authority or examiner regulating banks, banking or other financial institutions, (v) to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations under this Agreement on a confidential basis, (vi) to any credit insurance provider relating to the Borrower and its obligations on a confidential basis and (vii) pursuant to a request or requirement from a regulatory authority (governmental or non-governmental self- regulatory authority) having jurisdiction over a Lender; provided that unless prohibited by Applicable Law, each Lender and the Administrative Agent agree, prior to disclosure thereof, to notify the Borrower of any request for disclosure of any such Confidential Information (x) by any Governmental Authority or representative thereof (other than any such request in connection with an examination of such Lender or the Administrative Agent by such Governmental Authority) or (y) pursuant to legal process.

63

SECTION 8.09. Governing Law.

EACH LOAN DOCUMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5- 1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK), WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES THAT WOULD REQUIRE APPLICATION OF ANOTHER LAW.

SECTION 8.10. Severability.

SECTION 8.11. Execution in Counterparts.

This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Each party hereto agrees that a final judgment in any such action, litigation 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.

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

(c)Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 8.02. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by Applicable Law.

EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY) OR THE ACTIONS OF THE ADMINISTRATIVE AGENT, THE BORROWER OR ANY LENDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF. TO THE EXTENT THEY MAY LEGALLY DO SO, BORROWER, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY AGREE THAT ANY SUCH CLAIM, DEMAND, ACTION, CAUSE OF ACTION, OR PROCEEDING SHALL BE DECIDED BY A COURT TRIAL WITHOUT A JURY AND THAT ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE OTHER PARTY OR PARTIES HERETO TO WAIVER OF ITS OR THEIR RIGHT TO TRIAL BY JURY.

L. 107-56 (signed into law as of October 26, 2001)) (as amended, restated, modified or otherwise supplemented from time to time, the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide to the extent commercially reasonable, such information and take such actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act, including, without limitation, the Beneficial Ownership Regulation for the Borrower to the extent the Borrower qualifies as a “legal entity customer” under the Beneficial Ownership Regulation.

SECTION 8.15. No Fiduciary Duty.

The Credit Parties and their respective Affiliates (collectively, solely for purposes of this Section, the “Lender Parties”), may have economic interests that conflict with those of the Borrower, its securities holders and/or their Affiliates. The Borrower agrees that nothing in the Loan Documents will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between any Lender Party, on the one hand, and the Borrower, its securities holders or its Affiliates, on the other hand. The Borrower acknowledges and agrees that (i) the transactions contemplated by the Loan Documents (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Lender Parties, on the one hand, and the Borrower, on the other, and (ii) in connection therewith and with the process leading thereto, (x) no Lender Party has assumed an advisory or fiduciary responsibility in favor of the Borrower, its securities holders or its Affiliates with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Lender Party has advised, is currently advising or will advise the Borrower, its securities holders or its Affiliates on other matters), and (y) each Lender Party is acting solely as principal hereunder and under the other Loan Documents and not as the agent or fiduciary of the Borrower, its management, securities holders or creditors.

65

(iv)such other representation, warranty and covenant as may be agreed in writing between the Administrative Agent, in its sole discretion, and such Lender.

(b)In addition, unless either (1) sub-clause (i) in the immediately preceding clause (a) is true with respect to a Lender or (2) a Lender has provided another representation, warranty and covenant in accordance with sub-clause (iv) in the immediately preceding clause (a), such Lender further (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent, and not, for the avoidance of doubt, to or for the benefit of the Borrower, that the Administrative Agent is not a fiduciary with respect to the assets of such Lender involved in such Lender’s entrance into, participation in, administration of and performance of the Loans, the Commitments and this Agreement (including in connection with the reservation or exercise of any rights by the Administrative Agent under this Agreement, any Loan Document or any documents related hereto or thereto).

SECTION 8.19. Acknowledgement Regarding Any Supported QFCs.

To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Hedge Agreements or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and each such QFC a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (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 or of the United States or any other state of the United States):

(a)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.

(b)As used in this Section 8.19, the following terms have the following meanings:

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

“Covered Entity” means any of the following:

(i)a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b);

(ii)a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or

(iii)a “covered FSI” as that term is defined in, and interpreted in accordance with, 12

C.F.R. § 382.2(b).

67

“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.

“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).
