Agent will promptly make such funds available to the Borrower 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 Eurodollar Rate Revolving 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 Eurodollar Rate Revolving Loans shall then be suspended pursuant to Section 2.12(b), 2.13 or 2.16, and (ii) Borrowings of more than one Type and Class may be outstanding at the same time; provided, however, there shall be not more than 10 Borrowings 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 Eurodollar Rate Revolving 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 Revolving Loan to be made by such Lender as part of such Borrowing when such Revolving 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 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.

(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.

SECTION 2.03.    Swingline Loans.

(a)    Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrower from time to time on any Business Day during the period

from the date hereof until the Termination Date applicable to the Lender that is the Swingline Lender, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $20,000,000, or (ii) the Outstanding Credits exceeding the Commitments; provided that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Within the limits as hereinabove and hereinafter provided, the Borrower may request Swingline Borrowings hereunder, and repay or prepay Swingline Loans pursuant to Section 2.14 and utilize the resulting increase in the Available Commitments for further Extensions of Credit in accordance with the terms hereof. Each Swingline Loan shall be a Base Rate Loan and shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000.

(b)    To request a Swingline Loan, the Borrower shall notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 2:00 P.M. on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Borrower. The Swingline Lender shall make each Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower with the Swingline Lender by 4:00 P.M. on the requested date of such Swingline Loan.

(c)    The Swingline Lender may by written notice given to the Administrative Agent not later than 1:00 P.M. on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which the Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Commitment Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Commitment Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this subsection is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Swingline Loan shall utilize the Commitment of each Lender by an amount equal to the amount of such participation. Each Lender shall comply with its obligation under this subsection by wire transfer of immediately available funds, in the same manner as provided in Section 2.02(a) with respect to Loans made by such Lender (and Section 2.02 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this subsection, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be

promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this subsection (to the extent of each applicable Lender’s participation) and to the Swingline Lender to the extent of its retained interest; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this subsection shall not relieve the Borrower of any default in the payment thereof.

SECTION 2.04.    Letters of Credit.

(a)    Subject to the terms and conditions hereof, each LC Issuing Bank agrees to issue Letters of Credit from time to time for the account of the Borrower (or to extend the stated maturity thereof or to amend or modify the terms thereof), in an aggregate stated amount not exceeding such LC Issuing Bank’s Fronting Commitment, up to a maximum aggregate stated amount for all Letters of Credit at any one time outstanding equal to the LC Commitment Amount. With respect to Letters of Credit that are not Bond Letters of Credit, such issuance shall occur on not less than two Business Days’ prior notice thereof by the Borrower’s delivery of (x) a Request for Issuance for such Letter of Credit to the Administrative Agent and the LC Issuing Bank for such Letter of Credit and (y) such LC Issuing Bank’s standard form of Letter of Credit application for the requested Letter of Credit (including, for direct pay Letters of Credit, any reimbursement agreement or other standard form required by such LC Issuing Bank) to the letter of credit department of such LC Issuing Bank for the account of the Borrower. With respect to each Bond Letter of Credit, such issuance shall occur after receipt of (x) a Request for Issuance for such Bond Letter of Credit to the Administrative Agent and the LC Issuing Bank for such Bond Letter of Credit, (y) the Bond LC Reimbursement Agreement for such Bond Letter of Credit, as may be required by the LC Issuing Bank for such Bond Letter of Credit, and (z) the documents required pursuant to Section 3.03 and such Bond LC Reimbursement Agreement; provided that in the case of any Request for Issuance for an extension of an outstanding Bond Letter of Credit, such Request for Issuance shall be delivered to the Administrative Agent and the applicable LC Issuing Bank at least 90 days prior to the then-current Stated Expiry Date of such Bond Letter of Credit. Each Letter of Credit shall be issued in a form acceptable to the applicable LC Issuing Bank. Each Request for Issuance shall specify (i) the identity of the applicable LC Issuing Bank, (ii) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the Stated Expiry Date thereof, (iii) the proposed stated amount of such Letter of Credit (which amount (A) shall not be less than $100,000 and (B) may be subject to any automatic increase and reinstatement provisions), (iv) the name and address of the beneficiary of such Letter of Credit and (v) a statement of drawing conditions applicable to such Letter of Credit. If such Request for Issuance relates to an amendment or modification of a Letter of Credit that requires the consent of the beneficiary thereof, it shall be accompanied by such consent. If so requested by the Borrower, a Letter of Credit that is not a Bond Letter of Credit may provide that it is automatically renewable for additional one-year periods if subject to an ability of the applicable LC Issuing Bank to not renew by giving notice of the same to the beneficiary of such Letter of Credit. Each Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower prior to the issuance by the applicable LC Issuing Bank of the requested Letter of Credit or prior to the effectiveness of the requested extension, modification or amendment to a Letter of Credit, as applicable.

Upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the relevant LC Issuing Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Administrative Agent, which shall promptly furnish copies thereof to the Lenders that shall so request; provided that the LC Issuing Bank shall not issue or amend any Letter of Credit if such LC Issuing Bank has received notice from the Administrative Agent that the applicable conditions precedent have not been satisfied. Upon each issuance of a Letter of Credit by any LC Issuing Bank, each Lender shall be deemed, without further action by any party hereto, to have irrevocably and unconditionally purchased from such LC Issuing Bank without recourse a participation in such Letter of Credit equal to such Lender’s Commitment Percentage of the aggregate amount available to be drawn under such Letter of Credit. Upon each modification of a Letter of Credit by any LC Issuing Bank which modifies the aggregate amount available to be drawn under such Letter of Credit, such LC Issuing Bank and the Lenders shall be deemed, without further action by any party hereto, to have purchased or sold, as appropriate, participations in such Letter of Credit such that each Lender’s participation in such Letter of Credit shall equal such Lender’s Commitment Percentage of such modified aggregate amount available to be drawn under such Letter of Credit. Each Letter of Credit shall utilize the Commitment of each Lender in an amount equal to the amount of such participation. Without limiting the foregoing, any LC Issuing Bank that issues a Bond Letter of Credit agrees that (i) all Bonds pledged to such LC Issuing Bank pursuant to any applicable Pledge Agreement or otherwise registered in the name of such LC Issuing Bank pursuant to the other Related Documents will be held for the benefit of such LC Issuing Bank and the Lenders and (ii) to apply and/or remit all proceeds from the sale or remarketing of such Bonds in accordance with Section 2.17(f).

(b)    The Borrower may from time to time appoint one or more additional Lenders (with the consent of any such Lender, which consent may be withheld in the sole discretion of each Lender) to act, either directly or through an Affiliate of such Lender, as an LC Issuing Bank hereunder. Any such appointment and the terms thereof shall be evidenced in a separate written agreement executed by the Borrower and the relevant LC Issuing Bank, a copy of which agreement shall be delivered by the Borrower to the Administrative Agent. The Administrative Agent shall give prompt notice of any such appointment to the other Lenders. Upon such appointment, if and for so long as such Lender shall have any obligation to issue any Letter of Credit hereunder or any Letter of Credit issued by such Lender shall remain outstanding, such Lender shall be deemed to be, and shall have all the rights and obligations of, an “LC Issuing Bank” under this Agreement.

(c)    No Letter of Credit shall be requested, issued or modified hereunder if, after the issuance or modification thereof, (i) the Outstanding Credits would exceed the Commitments then scheduled to be in effect until the latest Termination Date, (ii) that portion of the LC Outstandings arising from Letters of Credit issued by an LC Issuing Bank would exceed the amount of such LC Issuing Bank’s Fronting Commitment or (iii) the LC Outstandings would exceed the LC Commitment Amount. No LC Issuing Bank shall be under any obligation to issue any Letter of Credit if any order, judgment or decree of any Governmental Authority shall by its terms purport to enjoin or restrain such LC Issuing Bank from issuing such Letter of Credit, or any law applicable to such LC Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such LC Issuing Bank shall prohibit, or request that the LC Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of

Credit in particular or shall impose upon the LC Issuing Bank with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the LC Issuing Bank is not otherwise compensated or required to be compensated hereunder), which restriction, reserve or capital requirement was not in effect on the date hereof, or shall impose upon the LC Issuing Bank any loss, cost or expense (not reimbursed or required to be reimbursed) that was not applicable on the date hereof and that the LC Issuing Bank in good faith deems material to it.

(d)    The Borrower hereby agrees to pay to the Administrative Agent for the account of each LC Issuing Bank and each Lender that has funded its participation in the reimbursement obligations of the Borrower pursuant to subsection (e) below, on demand made by such LC Issuing Bank to the Borrower, on and after each date on which such LC Issuing Bank shall pay any amount under any Letter of Credit issued by such LC Issuing Bank, a sum equal to the amount so paid (the “Reimbursement Amount”). Any Reimbursement Amount shall bear interest, payable on demand, from the date so paid by such LC Issuing Bank until repayment to such LC Issuing Bank in full at a fluctuating interest rate per annum equal to the interest rate applicable to Base Rate Loans plus, if any amount paid by such LC Issuing Bank under a Letter of Credit is not reimbursed by the Borrower within three Business Days, 2%. The Borrower may satisfy its obligation hereunder to repay the Reimbursement Amount by requesting a Borrowing under Section 2.02 (and which Borrowing shall be subject to the conditions in Section 2.02) in the amount of such Reimbursement Amount, and the proceeds of such Borrowing may be applied to satisfy the Borrower’s obligations to such LC Issuing Bank or the Lenders, as the case may be.

(e)    If any LC Issuing Bank shall not have been reimbursed in full for any Reimbursement Amount in respect of a Letter of Credit issued by such LC Issuing Bank on the date of such payment, such LC Issuing Bank shall give the Administrative Agent and each Lender prompt notice thereof (an “LC Payment Notice”) no later than 12:00 noon on the Business Day immediately succeeding the date of such payment by such LC Issuing Bank. Each Lender shall fund the participation that such Lender purchased pursuant to Section 2.04(a) by paying to the Administrative Agent for the account of such LC Issuing Bank an amount equal to such Lender’s Commitment Percentage of such Reimbursement Amount paid by such LC Issuing Bank, plus interest on such amount at a rate per annum equal to the Federal Funds Rate, for the first three days from the date of the payment by such LC Issuing Bank, and, thereafter, until the date of payment to such LC Issuing Bank by such Lender, at a rate of interest equal to the rate applicable to Base Rate Loans. Each such payment by a Lender shall be made not later than 3:00 P.M. on the later to occur of (i) the Business Day immediately following the date of such payment by such LC Issuing Bank and (ii) the Business Day on which such Lender shall have received an LC Payment Notice from such LC Issuing Bank. Each Lender’s obligation to make each such payment to the Administrative Agent for the account of such LC Issuing Bank shall be several and shall not be affected by the occurrence or continuance of a Default or the failure of any other Lender to make any payment under this Section 2.04(e). Each Lender further agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(f)    The failure of any Lender to make any payment to the Administrative Agent for the account of any LC Issuing Bank in accordance with subsection (e) above shall not relieve any other Lender of its obligation to make payment, but no Lender shall be responsible for the failure of any

other Lender. If any Lender (a “non-performing Lender”) shall fail to make any payment to the Administrative Agent for the account of any LC Issuing Bank in accordance with subsection (e) above, then for so long as such failure shall continue, such LC Issuing Bank shall be deemed, for purposes of Sections 6.01 and 8.01 hereof, to be a Lender owed a Borrowing in an amount equal to the outstanding principal amount due and payable by such non-performing Lender to the Administrative Agent for the account of such LC Issuing Bank pursuant to subsection (e) above. Any non-performing Lender and the Borrower (without waiving any claim against such non-performing Lender for such non-performing Lender’s failure to fund its participation in the reimbursement obligations of the Borrower under subsection (e) above) severally agree to pay to the Administrative Agent for the account of such LC Issuing Bank forthwith on demand such amount, together with interest thereon for each day from the date such non-performing Lender would have funded its participation had it complied with the requirements of subsection (e) above until the date such amount is paid to the Administrative Agent at (i) in the case of the Borrower, the interest rate applicable at the time to Base Rate Loans plus, if any amount paid by such LC Issuing Bank under a Letter of Credit is not reimbursed by the Borrower within three Business Days, 2%, in accordance with Section 2.04(d), and (ii) in the case of such non-performing Lender, the Federal Funds Rate, for the first three days and, thereafter, at a rate of interest equal to the rate applicable to Base Rate Loans.

(g)    The payment obligations of each Lender under Section 2.04(e) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i)    any lack of validity or enforceability of this Agreement or any other agreement or instrument relating thereto or to such Letter of Credit;

(ii)    any amendment or waiver of, or any consent to departure from, the terms of this Agreement or such Letter of Credit;

(iii)    the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any LC Issuing Bank, or any other Person, whether in connection with this Agreement, the transactions contemplated hereby, thereby or by such Letter of Credit, or any unrelated transaction;

(iv)    any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v)    payment in good faith by any LC Issuing Bank under the Letter of Credit issued by such LC Issuing Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit;

(vi)    the use that may be made of any Letter of Credit by, or any act or omission of, the beneficiary of any Letter of Credit (or any Person for which the beneficiary may be acting); or

(vii)    any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(h)    Without limiting any other provision of this Section 2.04, for purposes of this Section 2.04 any LC Issuing Bank may rely upon any oral, telephonic, telegraphic, facsimile, electronic, written or other communication believed in good faith to have been authorized by the Borrower, whether or not given or signed by an authorized Person of the Borrower.

(i)    The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither any LC Issuing Bank, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for, and the Borrower’s reimbursement obligation in respect of any Letter of Credit shall not be affected by, (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment by any LC Issuing Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; (iv) any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Letter of Credit or any financing institution or other party to whom any Letter of Credit may be transferred or any claims or defenses whatsoever of the Borrower or of its Affiliates against the beneficiary of any Letter of Credit or any such transferee; (v) any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit; or (vi) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that the Borrower and each Lender shall have the right to bring suit against each LC Issuing Bank, and each LC Issuing Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender that the Borrower or such Lender proves, in a court of competent jurisdiction by final and nonappealable judgment, were caused by such LC Issuing Bank’s willful misconduct or gross negligence. In furtherance and not in limitation of the foregoing, each LC Issuing Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by such LC Issuing Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by such LC Issuing Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by any LC Issuing Bank’s willful misconduct or gross negligence.

(j)    In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an LC Issuing Bank relating to any Letter of Credit issued by such LC Issuing Bank, the terms and conditions of this Agreement shall control. Unless otherwise

specified herein, the amount of a Letter of Credit at any time shall be deemed to be the stated amount of such Letter of Credit in effect at such time; provided, however, that with respect to any Letter of Credit that, by its terms or the terms of any application or other agreement related thereto, provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed to be the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at such time.

(k)    Any LC Issuing Bank may resign at any time by giving written notice thereof to the Administrative Agent, Lenders, the other LC Issuing Banks (if any) and the Borrower, provided that (i) there are no Letters of Credit outstanding with respect to such LC Issuing Bank at such time or (ii) unless the Borrower shall have agreed otherwise, another Lender or Affiliate thereof reasonably acceptable to the Borrower has agreed to serve as an LC Issuing Bank and commits in writing to issue one or more Letters of Credit in an aggregate amount at least equal to those of the resigning LC Issuing Bank. After the resignation of an LC Issuing Bank hereunder, such resigning LC Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an LC Issuing Bank under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase any existing Letter of Credit. Upon any such resignation, the Borrower and the resigning LC Issuing Bank may agree to replace or terminate any outstanding Letters of Credit issued by such LC Issuing Bank and to designate one or more Lenders as LC Issuing Banks to replace such LC Issuing Bank.

SECTION 2.05.    Fees.

(a)    The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee on the aggregate unused amount of such Lender’s Commitment (i) from the date hereof, in the case of each Initial Lender, and (ii) from the effective date specified in the Assignment and Assumption pursuant to which it became a Lender, in the case of each other Lender, in each case until the latest Termination Date applicable to such Lender, payable quarterly in arrears on the last day of each March, June, September and December, commencing June 30, 2014, and ending on such Termination Date. The commitment fee for any period will be equal to the Commitment Fee Rate in effect from time to time during such period, times an amount equal to the Commitments minus the aggregate principal amount of Loans and Letters of Credit outstanding during such period; provided, that for purposes of calculating the commitment fee, Swingline Loans shall not be considered outstanding Loans.

(b)    The Borrower agrees to pay the fees payable by the Borrower in such amounts and on such terms as set forth in the Fee Letters.

(c)    The Borrower agrees to pay to the Administrative Agent for the account of each Lender a fee (the “LC Fee”) on the average daily aggregate principal amount of each such Lender’s Commitment Percentage of the LC Outstandings (i) from the date hereof, in the case of each Initial Lender, and (ii) from the effective date specified in the Assignment and Assumption pursuant to which it became a Lender, in the case of each other Lender, in each case until the later to occur of (x) the Termination Date applicable to such Lender and (y) the date on which no Letters of Credit are outstanding, payable on the last day of each March, June, September and December (commencing

on June 30, 2014), and on such later date, at a rate equal at all times to the Applicable Margin in effect from time to time for Eurodollar Rate Revolving Loans.

SECTION 2.06.    Extension of the Termination Date.

(a)    Not earlier than 60 days prior to, nor later than 60 days after each anniversary of the date hereof, the Borrower may request by written notice made to the Administrative Agent (which shall promptly notify the Lenders thereof) a one-year extension of the Termination Date applicable to each Lender. Each Lender shall notify the Administrative Agent by the date specified by the Administrative Agent (which date shall be a Business Day and shall not be less than 15 days prior to, nor more than 30 days prior to, the Extension Effective Date) that either (A) such Lender declines to consent to extending the Termination Date or (B) such Lender consents to extending the Termination Date. Any Lender not responding within the above time period shall be deemed to have declined to extend the Termination Date. The consent of a Lender to any such extension shall be in the sole discretion of such Lender. The Administrative Agent shall, after receiving the notifications from all of the Lenders or the expiration of such period, whichever is earlier, notify the Borrower and the Lenders of the results thereof. The Borrower may request no more than two extensions pursuant to this Section.

(b)    If any Lender declines, or is deemed to have declined, to consent to such request for extension (each a “Declining Lender”), the Borrower shall have the right to replace such Declining Lender in accordance with Section 2.20(b). Any Lender replacing a Declining Lender shall be deemed to have consented to such request for extension (regardless of when such replacement is effective) and shall not be deemed to be a Declining Lender.

(c)    If the Required Lenders have consented to the extension of the Termination Date, the Termination Date of each Lender that consented to the extension shall be extended to the date that is one year after such Lender’s then-effective Termination Date, effective as of the date to be determined by the Administrative Agent and the Borrower (the “Extension Effective Date”). On or prior to the Extension Effective Date, (i) unless the Collateral Release has occurred, the Borrower shall have delivered to the Administrative Agent an amendment or replacement of each existing General and Refunding Mortgage Bond, extending the stated maturity date of such bond to the latest Termination Date as of the Extension Effective Date, each of which amendment or replacement bond shall be duly issued and delivered by a duly authorized officer of the Borrower and duly authenticated by the Indenture Trustee; and (ii) the Borrower shall have delivered to the Administrative Agent, in form and substance reasonably satisfactory to the Administrative Agent (A) the resolutions of the Borrower authorizing such extension (and, if applicable, such amendment or replacement of General and Refunding Mortgage Bonds) and all Governmental Approvals (if any) required in connection with such extension (and, if applicable, such amendment or replacement of General and Refunding Mortgage Bonds), certified as being in effect as of the Extension Effective Date and the related incumbency certificate of the Borrower, (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 amendment or replacement of General and Refunding Mortgage Bonds) and (C) a certificate of the Borrower stating that on and as of such Extension Effective Date, and after giving effect to the extension to be effective on such date, all conditions

precedent to an Extension of Credit under Section 3.02 are satisfied. On each Extension Effective Date, each Declining Lender being replaced by the Borrower pursuant to Section 2.06(b) shall have received payment in full of the principal amount of all Loans outstanding owing to such Declining Lender and all interest thereon and all fees and other amounts (including, without limitation, any amounts payable pursuant to Section 8.04(c)) payable to such Declining Lender accrued through such Extension Effective Date. Promptly following such Extension Effective Date, the Administrative Agent shall distribute an amended Schedule I to this Agreement (which shall thereafter be incorporated into this Agreement) to reflect any changes in the Lenders, the Commitments and each Lender’s Commitment Percentage as of such Extension Effective Date.

(d)    The Swingline Lender and each LC Issuing Bank may, in its sole discretion, elect not to serve in such capacity following any extension of the Termination Date; provided that (i) the Borrower and the Administrative Agent may appoint a replacement for such resigning Swingline Lender or LC Issuing Bank, as the case may be, and (ii) whether such replacement is appointed shall not otherwise affect the extension of the Termination Date.

SECTION 2.07.    Increase of the Commitments.

(a)    The Borrower may, from time to time, request by written notice to the Administrative Agent to increase the Commitments by a maximum aggregate amount for all such increases of up to $100,000,000, by designating one or more Lenders or other financial institutions (that will become Lenders), in each case, reasonably acceptable to the Administrative Agent and acceptable to the Swingline Lender and each LC Issuing Bank, in their respective sole discretion, that agree to accept all or a portion of such additional Commitments (each a “Designated Lender”).

(b)    The Administrative Agent shall promptly notify the Designated Lenders of the Borrower’s request pursuant to subsection (a) above. 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.

(c)    Promptly following the effective date of any Commitment increase pursuant to this Section 2.07, (i) the Administrative Agent shall distribute an amended Schedule I to this Agreement (which shall thereafter be incorporated into this Agreement) to reflect any changes in Lenders, the Commitments and each Lender’s Commitment Percentage as of such effective date and (ii) the Borrower shall prepay the outstanding Revolving Borrowings (if any) in full, and shall simultaneously make new Revolving Borrowings hereunder in an amount equal to such prepayment, so that, after giving effect thereto, the Revolving Borrowings are held ratably by the Lenders in accordance with their respective Commitments (after giving effect to such Commitment increase). Prepayments made under this clause (c) shall not be subject to the notice requirements of Section 2.14.

(d)    Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment increase and the making of any Loans on such date pursuant to clause (c)(ii) above, all calculations and payments of fees and of interest on the Loans shall take into account the actual Commitment of each Lender and the principal amount outstanding of each Loan made by such Lender during the relevant period of time. The Loans made or Letters of Credit issued 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 and Letters of Credit issued hereunder and shall constitute and be part of the “Obligations” arising under this Agreement.

SECTION 2.08.    Termination or Reduction of the Commitments.

(a)    The Borrower shall have the right, upon at least three Business Days’ notice to the Administrative Agent, to terminate in whole or reduce ratably in part the Available Commitments, provided that (i) each partial reduction shall be in the aggregate amount of $10,000,000 or an integral multiple of $5,000,000 in excess thereof and (ii) no such termination or reduction shall be made that would reduce the aggregate Commitments to an amount less than the Outstanding Credits on the date of such termination or reduction. Subject to the foregoing, any reduction of the Commitments to an amount below $75,000,000 shall also result in a reduction of the LC Commitment Amount to the extent of such deficit (and if such reduction would cause the LC Commitment Amount to be less than the aggregate Fronting Commitments, with automatic reductions in the amount of each Fronting Commitment ratably in proportion to the amount of such reduction of the LC Commitment Amount unless, in the case of any LC Issuing Bank, such LC Issuing Bank consents otherwise). 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, any LC Issuing Bank, the Swingline Lender or any Lender may have against such Defaulting Lender.

(c)    The Commitment of each Lender shall automatically terminate on the Termination Date applicable to such Lender as provided in Section 2.06.

(d)    Once terminated, a Commitment or any portion thereof may not be reinstated.

SECTION 2.09.    Repayment of Loans.

(a)    The Borrower shall repay to (i) the Administrative Agent for the account of each Lender on the Termination Date applicable to such Lender the aggregate principal amount of the Revolving Loans made to the Borrower by such Lender then outstanding and (ii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the latest Termination Date (or such earlier Termination Date beyond which the Swingline Lender has elected, pursuant to Section 2.06(d), not to act in such capacity) and the tenth Business Day after such Swingline Loan is made; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then outstanding. Without limiting the foregoing, the Borrower shall also repay (to the Administrative Agent for the account of the Lenders) Revolving Loans and (to the Swingline Lender) Swingline Loans, in each ease, to the extent and at the time required pursuant to the terms of any applicable Governmental Approval relating to the Borrower’s ability to incur Debt.

(b)    If at any time the aggregate principal amount of Outstanding Credits exceeds the Commitments, the Borrower shall pay or prepay so much of the Borrowings and/or Cash Collateralize the LC Outstandings as shall be necessary in order that the Outstanding Credits minus the principal amount of Cash Collateral securing the LC Outstandings will not exceed the Commitments.

SECTION 2.10.    Evidence of Indebtedness.

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

(b)    The Administrative Agent shall maintain accounts in which it will record (i) the amount of each Loan made hereunder, the Class and Type of each Loan made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

(c)    The entries made in the accounts maintained pursuant to subsections (a) and (b) of this Section 2.10 shall, to the extent permitted by Applicable Law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Loans and interest thereon in accordance with their terms.

(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. Thereafter, the Loans evidenced by such promissory notes and interest thereon shall at all times (including after assignment pursuant to Section 8.07) be represented by one or more promissory notes in such form payable to the payee named therein.

SECTION 2.11.    Interest on Loans.

The Borrower shall pay interest on the unpaid principal amount of each Loan from the date of such Loan until such principal amount shall be paid in full, at the following rates per annum:

(a)    Base Rate Loans. During such periods as such Loan is a Base Rate Revolving Loan or a Swingline Loan, a rate per annum equal at all times to the sum of (x) the Base Rate plus (y) the Applicable Margin for Base Rate Loans in effect from time to time, payable (A) in the case of Base Rate Revolving Loans, in arrears quarterly on the last day of each March, June, September and December during such periods and on the date such Base Rate Loan shall be Converted or paid in full, and (B) in the case of Swingline Loans, on the date such Swingline Loan is required to be paid in full as provided in Section 2.09.

(b)    Eurodollar Rate Revolving Loans. During such periods as such Revolving Loan is a Eurodollar Rate Revolving Loan, a rate per annum equal at all times during each Interest Period for such Revolving Loan to the sum of (x) the Eurodollar Rate for such Interest Period for such Revolving Loan plus (y) the Applicable Margin for Eurodollar Rate Revolving Loans in effect from time to time, payable in arrears on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Revolving Loan shall be Converted or paid in full.

(c)    Additional Interest on Eurodollar Rate Revolving Loans. The Borrower shall pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting

of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Revolving Loan of such Lender, from the date of such Revolving Loan until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Revolving Loan from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Revolving Loan. Such additional interest shall be determined by such Lender and notified to the Borrower through the Administrative Agent.

SECTION 2.12.    Interest Rate Determination.

(a)    The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.11(a) or (b), and, if applicable, the rate for the purpose of determining the applicable interest rate under Section 2.11(c).

(b)    If, with respect to any Eurodollar Rate Revolving Loans, (i) the Required Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Revolving Loans will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Revolving Loans for such Interest Period, or (ii) the Administrative Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (A) each Eurodollar Rate Revolving Loan will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Revolving Loan, and (B) the obligation of the Lenders to make, or to Convert Revolving Loans into, Eurodollar Rate Revolving Loans shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

SECTION 2.13.    Conversion of Revolving Loans.

(a)    Voluntary. The Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 12:00 noon on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.12 and 2.16, Convert all or any part of Revolving Loans of one Type comprising the same Borrowing into Revolving Loans of the other Type or of the same Type but having a new Interest Period; provided, however, that any Conversion of Eurodollar Rate Revolving Loans into Base Rate Revolving Loans shall be made only on the last day of an Interest Period for such Eurodollar Rate Revolving Loans, any Conversion of Base Rate Revolving Loans into Eurodollar Rate Revolving Loans shall be in an amount not less than the minimum amount specified in Section 2.02(b) and no Conversion of any Revolving Loans shall result in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Revolving Loans to be Converted, and (iii) if such Conversion is into Eurodollar Rate Revolving Loans, the duration of the initial Interest Period for each such Revolving Loan. Each notice of Conversion shall be irrevocable and binding on the Borrower. This Section shall not apply to Swingline Loans, which may not be Converted.

(b)    Mandatory.

(i)    If the Borrower shall fail to select the Type of any Revolving Loan or the duration of any Interest Period for any Borrowing comprising Eurodollar Rate Revolving 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 Borrowing that is to comprise Eurodollar Rate Revolving 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 Eurodollar Rate Revolving Loans are outstanding, the Administrative Agent will forthwith so notify the Borrower and the Lenders, and (i) such Revolving 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 Revolving Loans into, Eurodollar Rate Revolving Loans shall be suspended.

(ii)    On the date on which the aggregate unpaid principal amount of Eurodollar Rate Revolving Loans comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $10,000,000, such Revolving Loans shall automatically Convert into Base Rate Revolving Loans.

(c)    Failure to Convert. Each notice of Conversion given pursuant to subsection (a) above shall be irrevocable and binding on the Borrower. In the case of any Borrowing that is to comprise Eurodollar Rate Revolving Loans upon Conversion, the Borrower agrees to indemnify each Lender against any loss, cost or expense incurred by such Lender if, as a result of the failure of the Borrower to satisfy any condition to such Conversion (including, without limitation, the occurrence of any Default), such Conversion does not occur. The Borrower’s obligations under this subsection (c) shall survive the repayment of all Obligations and the termination of the Commitments.

(d)    Limitation on Certain Conversions. Notwithstanding any other provision of this Agreement to the contrary, the Borrower may not borrow Revolving Loans at the Eurodollar Rate or Convert Revolving Loans resulting in Eurodollar Rate Revolving 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 Eurodollar Rate Revolving Loans, and (ii) upon notice not later than 12:00 noon on the date of prepayment, in the case of Base Rate Revolving Loans and Swingline Loans, to the Administrative Agent (and, in the case of a Swingline Loan, the Swingline Lender) 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 Eurodollar Rate 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 (except any reserve requirement reflected in the Eurodollar Rate Reserve Percentage) or any LC Issuing Bank;

(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 any LC Issuing Bank or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

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 increase the cost to such Lender, such LC Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, LC Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount) then, upon the good faith request of such Lender, LC Issuing Bank or other Recipient, the Borrower will pay to such Lender, LC Issuing Bank or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, LC Issuing Bank or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b)    Capital Requirements. If any Lender or LC Issuing Bank determines that any Change in Law affecting such Lender or LC Issuing Bank or any lending office of such Lender or such Lender’s or LC Issuing Bank’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 or LC Issuing Bank’s capital or on the capital of such Lender’s or LC Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by any LC Issuing Bank, to a level below that which such Lender or LC Issuing Bank or such Lender’s or LC Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or LC Issuing Bank’s policies and the policies of such Lender’s or LC Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or LC Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or LC Issuing Bank or such Lender’s or LC Issuing Bank’s holding company for any such reduction suffered.

(c)    Certificates for Reimbursement. A certificate of a Lender or LC Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or LC Issuing Bank or its holding

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

SECTION 2.16.    Illegality.

If due to any Change in Law it shall become unlawful or impossible for any Lender (or its Eurodollar Lending Office) to make, maintain or fund its Eurodollar Rate Revolving Loans, and such Lender shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrower, whereupon, until such Lender notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Eurodollar Rate Revolving Loans, or to Convert outstanding Revolving Loans into Eurodollar Rate Revolving Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section 2.16, such Lender shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions applicable to such Lender) to designate a different Eurodollar Lending Office if such designation would avoid the need for giving such notice and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. If such notice is given, each Eurodollar Rate Revolving Loan of such Lender then outstanding shall be converted to a Base Rate Revolving Loan either (i) on the last day of the then current Interest Period applicable to such Eurodollar Rate Revolving Loan if such Lender may lawfully continue to maintain and fund such Revolving Loan to such day or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain and fund such Revolving Loan to such day.

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. on the day when due in Dollars to the Administrative Agent at the Agent’s Account (except payments to be made directly to the Swingline Lender as expressly provided herein) 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 Eurodollar Rate, the Federal Funds Rate or the rate referred to in clause (iii) of the definition of the “Base Rate” and of commitment fees and LC 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, commitment fees or LC 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 Eurodollar Rate Revolving Loans to be made in the next following calendar month or on a date after the Termination Date, such payment shall be made on the next preceding Business Day.

(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 Rate.

(f)    Notwithstanding anything to the contrary set forth in subsection (a) above or Section 2.04(d), the Borrower may pay, or cause to be paid pursuant to the applicable Related Documents, the Reimbursement Amount with respect to any drawing under a Bond Letter of Credit directly to the LC Issuing Bank that issued such Bond Letter of Credit. Upon receipt of any such payment,

such LC Issuing Bank will promptly (i) (A) apply such payment to that portion of such Reimbursement Amount participations in which have not been funded by the Lenders under Section 2.04(e)) and (B) remit the balance of such payment to the Administrative Agent for further payment to the Lenders that have funded participations in such Reimbursement Amount pursuant to Section 2.04(e), or (ii) if such Reimbursement Amount has been financed with Borrowings, remit such payment to the Administrative Agent, which will apply such payment to the prepayment of Borrowings in a principal amount equal to the principal amount of such Reimbursement Amount so financed. The Administrative Agent shall select the Borrowings to be prepaid pursuant to clause (ii) above in a manner that will mitigate, to the extent practical, the Borrower’s obligations under Section 8.04(c) with respect to such prepayment.

SECTION 2.18.    Taxes.

(a)    Defined Terms. For purposes of this Section 2.18 and for the avoidance of doubt, the term “Lender” includes any LC Issuing Bank and the Swingline Lender, and 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.

(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.

(i)    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), executed originals of 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, executed originals of 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, 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)    executed originals of 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) executed originals of IRS Form W-8BEN; or

(iv)    to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, 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.

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 Eurodollar Rate Revolving Loans converted into Base Rate Revolving 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 or participations in LC Outstandings 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 requires the Borrower 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 requires the Borrower 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 Declining Lender, a Defaulting Lender or a Non-Consenting 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);

(ii)    such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, any participations in Swingline Loans funded pursuant to Section 2.03(c) and any participations in Letters of Credit funded pursuant to Section 2.04(e), 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 Declining Lender or 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, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to any LC Issuing Bank or the Swingline Lender hereunder; third, to Cash Collateralize the LC Issuing Banks’ Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.22; fourth, 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; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order (x) to satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) to Cash Collateralize the LC Issuing Banks’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.22; sixth, to the payment of any amounts owing to the Lenders, the Issuing Banks or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the LC Issuing Banks or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Outstandings in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued 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, and LC Outstandings owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Outstandings owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in LC Outstandings and Swingline Outstandings are held by the Lenders pro rata in accordance with the Commitments without giving effect to Section 2.21(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.21(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii)    Certain Fees. (A) 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).

(A)    Each Defaulting Lender shall be entitled to receive LC Fees for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Commitment Percentage of the LC Outstandings for which it has provided Cash Collateral pursuant to Section 2.22.

(B)    With respect to any LC Fee not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such LC Fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in LC Outstandings that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to each LC Issuing Bank the amount of any such LC Fee otherwise payable to such Defaulting Lender to the extent allocable to such LC Issuing Bank’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such LC Fee.

(iv)    Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in LC Outstandings and Swingline Outstandings shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Commitment Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 3.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), (y) such reallocation does not cause the aggregate Outstanding Credits of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Commitment and (z) such reallocation does not cause the aggregate Outstanding Credits of all Non-Defaulting Lenders to exceed the Commitments of all Non-Defaulting Lenders. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v)    Cash Collateral, Repayment of Swingline Loans. If the reallocation described in paragraph (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (x) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s Fronting Exposure and (y) second, Cash Collateralize the LC Issuing Banks’ Fronting Exposure in accordance with the procedures set forth in Section 2.22.

(vi)    Reduction of Available Commitments. The Borrower may terminate the Available Commitment of any Lender that is a Defaulting Lender in accordance with Section 2.08(b).

(b)    Defaulting Lender Cure. If the Borrower, the Administrative Agent, the Swingline Lender and each LC Issuing Bank 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 (which may include arrangements with respect to any Cash Collateral), 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 and funded and unfunded participations in LC Outstandings and Swingline Outstandings to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 2.21(a)(iv)), 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.

(c)    New Swingline Loans/Letters of Credit. So long as any Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan and (ii) no LC Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

(d)    Bankruptcy Event of a Parent Company. If (i) a Bankruptcy Event with respect to a direct or indirect parent company of any Lender shall occur following the date hereof and for so long as such event shall continue or (ii) the Swingline Lender or any LC Issuing Bank has a good faith belief that any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Swingline Lender shall not be required to fund any Swingline Loan, and no LC Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit, unless the Swingline Lender or such LC Issuing Bank, as the case may be, shall have entered into arrangements with the Borrower or such Lender, satisfactory to the Swingline Lender or such LC Issuing Bank, as the case may be, to defease any risk to it in respect of such Lender hereunder.

SECTION 2.22.    Cash Collateral.

At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or any LC Issuing Bank (with a copy to the Administrative Agent) the Borrower shall Cash Collateralize the LC Issuing Banks’ Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to Section 2.21(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount.

(i)    Grant of Security Interest. The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of the LC Issuing Banks, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of LC Outstandings, to be applied pursuant to paragraph (ii) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent and the LC Issuing Banks as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii)    Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.22 or Section 2.21 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of LC Outstandings (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii)    Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce any LC Issuing Bank’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 2.22 following (A) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (B) the determination by the Administrative Agent and each LC Issuing Bank that there exists excess Cash Collateral; provided that, subject to Section 2.21, the Person providing Cash Collateral and each LC Issuing Bank may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations.

(e)    Each Loan Document is the legal, valid and binding obligation of the Borrower, enforceable against the Borrower in accordance with its terms, except as limited by bankruptcy and similar laws affecting the enforcement of creditors’ rights generally and by the application of general equitable principles.

(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, 2013, 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. The consolidated balance sheet of the Borrower and its Consolidated Subsidiaries as at March 31, 2014, and the related consolidated statements of income, cash flows and stockholders’ equity for the fiscal quarter ended on such date, copies of which have heretofore been furnished to the Administrative Agent and each Lender, present fairly in all material respects the consolidated 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 quarter then ended (subject to normal year-end audit adjustments).

There are no actions, suits or claims pending against or involving a Pension Plan (other than routine claims for benefits) or, to the knowledge of the Borrower or any of its ERISA Affiliates, threatened, that would reasonably be expected to be asserted successfully against any Pension Plan and, if so asserted successfully, would reasonably be expected either singly or in the aggregate to have a Material Adverse Effect.

(o)    No written statement or information furnished by or on behalf of the Borrower to the Administrative Agent, any Lender or any LC Issuing Bank 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.

None of the Borrower or any of its Subsidiaries, nor, to the knowledge of the Borrower, any of their respective officers, directors or employees, or any agent of the Borrower or its Subsidiary that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person. None of the Borrower or any of its Subsidiaries (i) has assets located in Sanctioned Countries in violation of Sanctions, (ii) does business in or with, or derives its operating income from investments in, or transactions with, Sanctioned Persons in violation of Sanctions or (iii) does business in or with, or derives its operating income from investments in, or transactions with, Sanctioned Countries in violation of Sanctions.

(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. At all times prior to the Collateral Release, the Borrower has all requisite corporate power and authority to issue and deliver the General and Refunding Mortgage Bonds in accordance with and upon the terms and conditions set forth herein.

(e)    Any judgment or order for the payment of money in excess of $50,000,000 to the extent not paid or insured shall be rendered against the Borrower or any Material Subsidiary and either (i) enforcement proceedings shall have been commenced by any creditor upon such judgment or order or (ii) there shall be any period of 30 consecutive days during which a stay of enforcement of such judgment or order, by reason of a pending appeal or otherwise, shall not be in effect; or

(f)    The Borrower or any Material Subsidiary shall generally not pay its debts as such debts become due, or shall admit in writing its inability to pay its debts generally, or shall make a general assignment for the benefit of creditors; or any proceeding shall be instituted by or against the Borrower or any Material Subsidiary seeking to adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition

of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee, custodian or other similar official for it or for any substantial part of its property and, in the case of any such proceeding instituted against it (but not instituted by it), either such proceeding shall remain undismissed or unstayed for a period of 60 days, or any of the actions sought in such proceeding (including, without limitation, the entry of an order for relief against, or the appointment of a receiver, trustee, custodian or other similar official for, it or for any substantial part of its property) shall occur; or the Borrower or any Material Subsidiary shall take any corporate action to authorize any of the actions set forth above in this subsection (f); or

(g)    An ERISA Event shall have occurred that, when taken together with all other ERISA Events that have occurred, has resulted in, or is reasonably likely to result in, a Material Adverse Effect; or

(h)    (i) Berkshire Hathaway shall fail to own, directly or indirectly, at least 50% of the issued and outstanding shares of common stock of the Borrower, calculated on a fully diluted basis or (ii) Berkshire Hathaway Energy Company shall fail to own, directly or indirectly, at least 80% of the issued and outstanding shares of common stock of the Borrower, calculated on a fully diluted basis (each, a “Change of Control”); provided that, in each case of the foregoing clauses (i) and (ii), such failure shall not constitute an Event of Default unless and until a Rating Decline has occurred; or

(i)    At any time prior to the Collateral Release, any of the Loan Documents shall cease for any reason to be in full force and effect or any material provision of the General and Refunding Mortgage Indenture (or any security documents executed in connection therewith) shall cease for any reason to be in full force and effect, or the Borrower or any Affiliate of the Borrower shall so assert; or any Lien created by any of the Loan Documents or the General and Refunding Mortgage Indenture (or any security documents executed in connection therewith) shall cease to be enforceable and of the same effect and priority purported to be created thereby with respect to any material portion of the collateral; or

(j)    At any time prior to the Collateral Release, any “Event of Default” under (and as defined in) the General and Refunding Mortgage Indenture shall occur;

then, and in any such event, the Administrative Agent (i) shall at the request, or may with the consent, of the Required Lenders, by notice to the Borrower, declare the obligation of the Swingline Lender, each Lender and each LC Issuing Bank to make Extensions of Credit to be terminated, whereupon the same shall forthwith terminate; (ii) shall at the request, or may with the consent, of the Required Lenders, by notice to the Borrower, declare the outstanding Borrowings, all interest thereon and all other Obligations (other than Hedging Obligations and Treasury Management Obligations) to be forthwith due and payable, whereupon the outstanding Borrowings, all such interest and all such other Obligations shall become and be forthwith due and payable by the Borrower, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower; (iii) shall at the request, or may with the consent, of the Required Lenders by notice to the Borrower, give notice of the occurrence of an Event of Default to the Bond Trustee for each series of Bonds supported by a Bond Letter of Credit issued for the account of the Borrower

and instruct such Bond Trustee either to accelerate such Bonds, thereby causing such Bond Letter of Credit to expire thereafter, per the terms of such Bond Letter of Credit, or to effect a mandatory tender of such Bonds; (iv) shall at the request, or may with the consent, of the Required Lenders by notice to the Borrower, pursue any rights and remedies on behalf of the Lenders and the applicable LC Issuing Bank that the Administrative Agent may have under the Related Documents executed and delivered in connection with any Bond Letter of Credit; and (v) shall at the request, or may with the consent, of the Required Lenders, by notice to the Borrower, exercise on behalf of the Lenders all of its other rights and remedies under this Agreement, the General and Refunding Mortgage Bonds, the General and Refunding Mortgage Indenture, the other Loan Documents and Applicable Law, in order to satisfy all of the Obligations; provided, however, that in the event of an actual or deemed entry of an order for relief with respect to the Borrower under the Bankruptcy Code of the United States of America, (A) the obligation of the Swingline Lender, each Lender and each LC Issuing Bank to make Extensions of Credit shall automatically be terminated and (B) the outstanding Borrowings, all such interest and all such other Obligations (other than Hedging Obligations and Treasury Management Obligations) shall automatically become and be due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby expressly waived by the Borrower.

In addition, if an “Event of Default” (or any other similar term) under and as defined in any Bond Indenture executed and delivered in connection with any Bond Letter of Credit (a “Bond Event of Default”) shall have occurred and be continuing, such circumstance shall constitute an Event of Default hereunder solely for the purpose of permitting the exercise of the remedies described in clauses (iii) and (iv) of the immediately preceding paragraph with respect to the Bonds for which such Bond Event of Default exists and the related Bond Letter of Credit and not for any other purpose under this Agreement. For the avoidance of doubt, a Bond Event of Default shall not give the Administrative Agent the right to exercise any other remedy described in the immediately preceding paragraph, unless such Bond Event of Default, or the facts and circumstances underlying such Bond Event of Default, gives rise to another Event of Default otherwise described in Section 6.01.

SECTION 6.02.    Actions in Respect of the Letters of Credit upon Default.

If any Event of Default described in Section 6.01(f) with respect to the Borrower shall have occurred and be continuing or the Borrowings shall have otherwise been accelerated or the Commitments terminated pursuant to Section 6.01, then the Administrative Agent may, or shall at the request of the Required Lenders, make demand upon the Borrower to, and forthwith upon such demand the Borrower will, deposit in an account designated in such demand (the “LC Collateral Account”) with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders and LC Issuing Banks, in same day funds, an amount equal to 103% of the aggregate undrawn stated amounts of all Letters of Credit that are outstanding on such date. If at any time the Administrative Agent determines that any funds held in the LC Collateral Account are subject to any right or claim of any Person other than the Administrative Agent, the Lenders and the LC Issuing Banks or that the total amount of such funds is less than 103% of the aggregate undrawn stated amounts of all Letters of Credit that are outstanding on such date, the Borrower will, forthwith upon demand by the Administrative Agent, pay to the Administrative Agent, as

additional funds to be deposited and held in the LC Collateral Account, an amount equal to the excess of (i) 103% of such aggregate undrawn stated amounts of all Letters of Credit that are outstanding on such date over (ii) the total amount of funds, if any, then held in the LC Collateral Account that the Administrative Agent determines to be free and clear of any such right and claim. Upon the drawing of any Letter of Credit for which funds are on deposit in the LC Collateral Account, such funds shall be applied to reimburse the relevant LC Issuing Bank or Lender holding a participation in the reimbursement obligation of the Borrower to such LC Issuing Bank to the extent permitted by Applicable Law.

SECTION 7.01.    Appointment and Authority.

Each of the Swingline Lender, each Lender and each LC Issuing Bank hereby irrevocably appoints Wells Fargo Bank to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and the Related 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 of the Swingline Lender, each Lender and each LC Issuing Bank 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 Swingline Lender, the Lenders and the LC Issuing Banks, 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 or any Related Document (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

SECTION 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 “Swingline Lender”, “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 in the Related 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 or by the Related 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 or in the Related 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, any Related 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

(iii)    shall not, except as expressly set forth herein, in the other Loan Documents or in the Related 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, 6.02 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, a Lender or an LC Issuing Bank.

(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 or any Related 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, any Related 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, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of the Swingline Lender, a Lender or an LC Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to the Swingline Lender, such Lender or such LC Issuing Bank unless the Administrative Agent shall have received notice to the contrary from the Swingline Lender, such Lender or such LC Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. 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 Swingline Lender, the Lenders, the LC Issuing Banks 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 Swingline Lender, the Lenders and the LC Issuing Banks, 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.

(b)    If the Person serving as Administrative Agent is a Defaulting Lender pursuant to clause (d) of 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 the Swingline Lender, each Lender and each LC Issuing Bank directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring 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 or under the Related 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 and under the Related 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 (including cash collateral and collateral held under any Pledge Agreement) as bailee for the benefit of the LC Issuing Banks and 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 and LC Issuing Bank 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 and LC Issuing Bank 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, any Related Document or any related agreement or any document furnished hereunder or thereunder.

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 Related Document or any action taken or omitted by the Administrative Agent under this Agreement, any other Loan Document or any Related 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 Global Coordinator, the Joint Lead Arrangers, the “Joint Bookrunners”, the “Syndication Agents” or the “Documentation Agents” listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement, any other Loan Document or any Related Document, except in its capacity, as applicable, as the Administrative Agent, a Lender or an LC Issuing Bank 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 of the Swingline Lender, each Lender and each LC Issuing Bank 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) 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) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to the Administrative Agent and the applicable LC Issuing Bank in their sole discretion shall have been made) 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.

(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 8.01.    Amendments, Etc.

Subject to Section 2.21(a)(i), no amendment or waiver of any provision of this Agreement, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Required Lenders and the Borrower, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that, no amendment, waiver or consent shall, unless in writing and signed by each Lender directly affected thereby (other than, in the case of clause (i), (v) or (vi) below, any Defaulting Lender), do any of the following: (i) amend Section 3.01, 3.02 or 3.03 or waive any of the conditions specified therein, (ii) increase the Commitment of any Lender or extend the Commitments (except pursuant to Section 2.06 or 2.07), (iii) reduce the principal of, or interest on, or rate of interest applicable to, the outstanding Loans or any fees or other amounts payable hereunder, (iv) postpone any date fixed for any payment of principal of, or interest on, the outstanding Loans, reimbursement obligations or any fees or other amounts payable hereunder, (v) change the definition of Required Lenders or change the percentage of the Commitments or of the aggregate unpaid principal amount of the outstanding Borrowings, or the number or the percentage of Lenders, that shall be required for the Lenders or any of them to take any action hereunder, (vi) amend or waive this Section 8.01 or any provision of this Agreement that requires pro rata treatment of the Lenders, (vii) take any action that would result in the General and Refunding Mortgage Bonds no longer being secured equally and ratably with all other Securities (as defined in the General and Refunding Mortgage Indenture) issued and outstanding under the General and Refunding Mortgage Indenture or no longer being secured by direct and valid, duly perfected Liens on and security

interests in the Mortgaged Property, subject only to Permitted Liens (as defined in the General and Refunding Mortgage Indenture), (viii) release the General and Refunding Mortgage Bonds, except pursuant to the terms thereof or in accordance with Section 7.09 hereof, or, prior to the Collateral Release, change any provision of the General and Refunding Mortgage Bonds providing for the release of the General and Refunding Mortgage Bonds; and provided further that (x) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent, the Swingline Lender or any LC Issuing Bank in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative Agent, the Swingline Lender or such LC Issuing Bank, as the case may be, under this Agreement, and (y) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent, the Swingline Lender, each LC Issuing Bank and the Required Lenders, amend or waive Section 2.21. Prior to the Collateral Release, the Administrative Agent, as holder of the General and Refunding Mortgage Bonds, will not consent to any amendment or other modification of the General and Refunding Mortgage Indenture that requires the consent of holders of all securities issued thereunder, without the consent of each Lender. Notwithstanding the foregoing, any provision of this Agreement may be amended by an agreement in writing entered into by the Borrower, the Required Lenders and the Administrative Agent if by the terms of such agreement the Commitment of each Lender and the obligations of each LC Issuing Bank not consenting to the amendment provided for therein shall terminate upon the effectiveness of such amendment (but such Lender or LC Issuing Bank shall continue to be entitled to the benefits of Sections 2.15, 2.18 and 8.04), and such Lender or LC Issuing Bank shall have received payment of an amount equal to the outstanding principal of its Loans, any participations in Swingline Loans funded pursuant to Section 2.03(c) and any participations in Letters of Credit funded pursuant to Section 2.04(e), together with all applicable accrued interest thereon, accrued fees and all other amounts then payable to it hereunder and under the other Loan Documents.

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 and its 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, and (ii) all reasonable out‑of‑pocket expenses incurred by any LC Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder. The Borrower further agrees to pay promptly upon demand all reasonable costs and expenses of the Administrative Agent, the Swingline Lender, the Lenders and the LC Issuing Banks, if any, (A) in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement and the other Loan Documents, including its rights under this Section, or (B) in connection with the Loans made or Letters of Credit issued hereunder, including all such reasonable out-of-pocket expenses incurred

during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit, including, without limitation, reasonable fees and expenses of counsel for the Administrative Agent, the Swingline Lender, the Lenders and the LC Issuing Banks in connection with the enforcement of rights under this Section 8.04(a).

(b)    The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), the Swingline Lender, each Lender and each LC Issuing Bank, 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 Extensions of Credit, 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 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 Extensions of Credit. 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 Eurodollar Rate Revolving 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 Revolving Loan, as a result of a payment or Conversion pursuant to Section 2.06(c), 2.07(c), 2.09, 2.12(b), 2.13, 2.14, 2.15 or 2.16, acceleration of the maturity of the outstanding Borrowings 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 2.16, 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 Extensions of Credit 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.

(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 Borrowings due and payable pursuant to the provisions of Section 6.01, each Lender, each LC Issuing Bank, the Swingline 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, such LC Issuing Bank, the Swingline 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, such LC Issuing Bank or the Swingline Lender or their respective Affiliates, irrespective of whether or not such Lender, such LC Issuing Bank, the Swingline 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, such LC Issuing Bank or the Swingline 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, the Swingline Lender, the LC Issuing Banks, 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, each LC Issuing Bank, the Swingline Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, such LC Issuing Bank, the Swingline Lender or their respective Affiliates may have. Each Lender, each LC Issuing Bank and the Swingline 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 Initial Lender that such Initial Lender has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, the Swingline Lender, each Lender and each LC Issuing Bank (upon its appointment pursuant to Section 2.04) 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, the Swingline Lender, each Lender and each LC Issuing Bank, 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 (f) 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, the Swingline Lender, the LC Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(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 Commitment 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, an Affiliate of a Lender or an Approved Fund; 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 notice thereof;

(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, an Affiliate of such Lender or an Approved Fund; and

(C)    the consent of each LC Issuing Bank and Swingline Lender shall be required for any assignment.

(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.

(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, each LC Issuing Bank, each Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline 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, 2.18 and 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 Termination Date of, 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, the Swingline Lender, any LC Issuing Bank 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, the LC Issuing Banks 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).

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 2.19 as 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, Letters of Credit 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, Letter of Credit 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 (vi) 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.

SECTION 8.09.    Governing Law.

EACH LOAN DOCUMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW 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.

In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired hereby.

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. Delivery of an executed counterpart of a signature page to this Agreement by telecopier or other electronic transmission (including by e-mail with a PDF attachment of an executed counterpart) shall be effective as delivery of an original executed counterpart of this Agreement.

SECTION 8.12.    Jurisdiction, Etc.

(a)    Each party hereto hereby irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Administrative Agent, the Swingline Lender, any Lender, any LC Issuing Bank, or any Related Party of the foregoing in any way relating to this Agreement or any other Loan Document or the transactions relating hereto or thereto, in any forum other than the courts of the State of New York sitting in the Borough of Manhattan in New York City, and of the United States District Court of the Southern District of New York sitting in the Borough of Manhattan in New York City, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such  courts and agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by applicable law, in such federal court.  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.

SECTION 8.13.    Waiver of Jury Trial.

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 SWINGLINE LENDER, ANY LC ISSUING BANK, 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, THE SWINGLINE LENDER, THE LC ISSUING BANKS 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.

Each Lender that is subject to the Patriot Act and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law 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.

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 or the Related 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 and the Related 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, under the other Loan Documents and the Related Documents and not as the agent or fiduciary of the Borrower, its management, securities holders or creditors. The Borrower acknowledges and agrees that it has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. The Borrower agrees that it will not claim that any Lender Party has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Borrower, in connection with the transactions contemplated by the Loan Documents or the Related Documents or the process leading thereto.

SECTION 8.16.    Reaffirmation of Loan Documents.

The Borrower hereby ratifies and reaffirms all of its payment and performance obligations, contingent or otherwise, under each of the Loan Documents. The Borrower acknowledges and agrees that (i) its obligations under each of the Loan Documents are not impaired or affected by the execution, delivery and performance of this Agreement or the consummation of the transactions contemplated thereby, including the making of the Loans and other extensions of credit hereunder, and that all Liens granted as security for the Obligations continue in full force and effect, (ii) the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, including the making of the Loans and other extensions of credit hereunder, is not a defense to the obligations of the Borrower under any Loan Document, and (iii) each Loan

Document remains in full force and effect and is hereby ratified and reaffirmed in all respects.

This opinion is furnished to you pursuant to Section 3.01(a)(v) of the Amended and Restated Credit Agreement, dated as of June 27, 2014 (the “Credit Agreement”), among Sierra Pacific Power Company (the “Borrower”), the Lenders and LC Issuing Banks party thereto and Wells Fargo Bank, National Association, as Administrative Agent and Swingline Lender. Terms defined in the Credit Agreement are used herein as therein defined.

I am an Associate General Counsel for NV Energy, Inc., direct parent of the Borrower, and have acted as counsel to the Borrower in connection with the preparation, execution and delivery of the Credit Agreement and the other Loan Documents (as defined below). I am generally familiar with the Borrower’s corporate history, properties, operations and charter (including amendments, restatements and supplements thereto).

In connection with this opinion, I, or attorneys over whom I exercise supervision, have examined:

In addition, I, or attorneys over whom I exercise supervision, have examined the originals, or copies certified to my satisfaction, of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as I have deemed necessary as a basis for the opinions expressed below.

In my examination, I, or attorneys over whom I exercise supervision, have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. In making our examination of documents and instruments executed or to be executed by persons other than the Borrower, I, or attorneys over whom I exercise supervision, have assumed that each such other person had the requisite power and authority to enter into and perform fully its obligations thereunder, the due authorization by each such other person for the execution, delivery and performance thereof and the due execution and delivery thereof by or on behalf of such person of each such document and instrument. In the case of any such person that is not a natural person, I, or attorneys over whom I exercise supervision, have also assumed, insofar as it is relevant to the opinions set forth below, that each such other person is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it was created and is duly qualified and in good standing in each other jurisdiction where the failure to be so qualified could reasonably be expected to have a material effect upon its ability to execute, deliver and/or perform its obligations under any such document or instrument. I, or attorneys over whom I exercise supervision, have further assumed that each document, instrument, agreement, record and certificate reviewed by us for purposes of rendering the opinions expressed below has not been amended by any oral agreement, conduct or course of dealing between the parties thereto.

As to questions of fact material to the opinions expressed herein, I have relied upon certificates and representations of officers of the Borrower (including but not limited to those contained in the Credit Agreement and certificates delivered upon the execution and delivery of the Credit Agreement) and of appropriate public officials, without independent verification of such matters except as otherwise described herein.

Whenever my opinions herein with respect to the existence or absence of facts are stated to be to my knowledge or awareness, it is intended to signify that no information has come to my attention or the attention of other counsel working under my direction in connection with the preparation of this opinion letter that would give me or them actual knowledge of the existence or absence of such facts. However, except to the extent expressly set forth herein, neither I nor they have undertaken any independent investigation to determine the existence or absence of such facts, and no inference as to my or their knowledge of the existence or absence of such facts should be assumed.

I am admitted to the practice of law in the State of Nevada and do not purport to be expert on the laws of any jurisdiction other than the laws of the State of Nevada and the Federal laws of the United States. My opinions expressed below are limited to the laws of the State of Nevada that are applicable to Borrower as a regulated public utility in such state, and the Federal law of the United States.

Based upon the foregoing and upon such investigation as I have deemed necessary, and subject to the limitations, qualifications and assumptions set forth herein, I am of the following opinion:

I express no opinion as to (i) Section 8.05 of the Credit Agreement and (ii) the effect of the law of any jurisdiction wherein any Lender may be located which limits the rates of interest which may be charged or collected by such Lender.

This opinion letter has been rendered solely for your benefit in connection with the Credit Agreement and the transactions contemplated thereby and may not be used, circulated, quoted, relied upon or otherwise referred to by any other person (other than your respective counsel, auditors and any regulatory agency having jurisdiction over you or as otherwise required pursuant to legal process or other requirements of law) for any other purpose without my prior written consent; provided that, (i) King & Spalding LLP, special counsel for the Administrative Agent, may rely on the opinions expressed in this opinion letter in connection with the opinion to be furnished by them in connection with the transactions contemplated by the Credit Agreement and (ii) any person that becomes a Lender or an LC Issuing Bank after the date hereof may rely on the opinions expressed in this opinion letter as though addressed to such person. I undertake no responsibility to update or supplement this opinion in response to changes in law or future events or circumstances.

We have acted as special counsel to Sierra Pacific Power Company, a Nevada corporation (the “Company”), in connection with the Amended and Restated Credit Agreement dated as of June 27, 2014 (the “Credit Agreement) by and among the Company, certain lenders (the “Lenders”), and Wells Fargo Bank, National Association, as administrative agent (in such capacity, the “Administrative Agent”) and a Lender. Each capitalized term used and not defined herein has the meaning assigned to that term in the Credit Agreement. This opinion is delivered pursuant to Section 3.01(a)(vi) of the Credit Agreement.

In rendering this opinion, we have examined the originals, or copies, certified or otherwise identified to our satisfaction as being true copies, of the following documents and instruments:

(i)the Credit Agreement, including the Exhibits and Schedules thereto;

(ii)    the Notes dated June 27, 2014 (the “Notes”) made by the Company payable to certain Lenders and delivered on the date hereof;

(iii)    the General and Refunding Mortgage Bond, Series S-1, No. S-1-1, dated June 27, 2014 (the “Bond”) made by the Company payable to the Administrative Agent;

(iv)    the General and Refunding Mortgage Indenture, dated as of May 1, 2001 (the “Indenture”) between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee;

(v)    the Board Resolution approving the execution, delivery, performance and issuance of the Bond and authorizing the form and terms thereof to be established pursuant to an Officer’s Certificate (the “Resolutions”); and

(vi)    the Officer’s Certificate of the Company dated the date hereof (the “Bond Terms Officer’s Certificate”) establishing the form and terms of the Bond pursuant to Sections 2.01 and 3.01 of the Indenture and the Resolutions.

The Credit Agreement, the Notes, and the Bond collectively are referred to herein as the “Financing Documents.”

(a)The signatures on all documents examined by us are genuine, all individuals executing such documents had all requisite legal capacity and competency and were duly authorized, the documents submitted to us as originals are authentic and the documents submitted to us as certified or reproduction copies conform to the originals;

(b)    (1) The Company is a validly existing corporation in good standing under the laws of the State of Nevada and has all requisite corporate power to execute and deliver each of the Financing Documents and to perform its obligations thereunder, (2) the execution and delivery of each of the Financing Documents by the Company and performance of its obligations thereunder have been duly authorized by all necessary corporate or other action and, except as specifically addressed in our opinions in paragraph 2 below, do not violate any law, rule, regulation, order, judgment or decree applicable to the Company, and (3) each of the Financing Documents has been duly executed and delivered by the Company; and

(c)    There are no agreements or understandings between or among any of the parties to the Financing Documents or third parties that would expand, modify or otherwise affect the terms of the Financing Documents or the respective rights or obligations of the parties thereunder.

In rendering this opinion, we have made such inquiries and examined, among other things, originals or copies, certified or otherwise identified to our satisfaction, of such records, agreements, certificates, instruments and other documents as we have considered necessary or appropriate for purposes of this opinion. As to certain factual matters, we have relied to the extent we deemed appropriate and without independent investigation upon the representations and warranties of the Company in the Financing Documents, officer’s certificates of officers of the Company or certificates obtained from public officials and others.

Based upon the foregoing and in reliance thereon, and subject to the qualifications, exceptions, assumptions and limitations herein contained, we are of the opinion that:

1.Each of the Credit Agreements and each Note constitutes a legal, valid and binding obligation of the Company, enforceable against it in accordance with its terms.

2.    The execution and delivery by the Company of the Financing Documents, and the performance of its obligations thereunder do not and will not violate, or require any filing with or approval of any governmental authority or regulatory body of the State of New York or the United States of America under, any law, rule or regulation of the State of New York or the United States of America applicable to the Company that, in our experience, is generally applicable to transactions in the nature of those contemplated by the Financing Documents.

3.     (i) The conditions set forth in the Indenture to the issuance and authentication of the Bond have been satisfied, (ii) the form of the Bond has been established in conformity with the provisions of the Indenture, (iii) the terms of the Bond have been established in conformity with the provisions of the Indenture, and (iv) the Bond, when authenticated and delivered by the Trustee and issued and delivered by the Company, pursuant to the terms of the Resolutions and Bond Terms Officer’s Certificate, as requested in the Company Order (as defined in the Indenture), will constitute a valid obligation of the Company, entitled to the benefit of the Lien of the Indenture equally and ratably with all other Securities (as defined in the Indenture) then Outstanding (as defined in the Indenture).

A.We render no opinion herein as to matters involving the laws of any jurisdiction other than the State of New York and the United States of America. This opinion is limited to the effect of the current state of the laws of the State of New York and the United States of America and the facts as they currently exist. We assume no obligation to revise or supplement this opinion in the event of future changes in such laws or the interpretations thereof or such facts. We express no opinion regarding (i) the Securities Act of 1933, as amended, the Investment Company Act of 1940, as amended, or any other federal or state securities laws, rules or regulations or the effect of any non-compliance therewith or (ii) any federal or state utility or energy laws, rules or regulations or the effect of any non-compliance therewith.

B.    Our opinion in paragraph 1 is subject to (i) the effect of any bankruptcy, insolvency, reorganization, moratorium, arrangement or similar laws affecting the rights and remedies of creditors generally (including, without limitation, the effect of statutory or other laws regarding fraudulent transfers or preferential transfers or distributions by corporations to stockholders) and (ii) general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies regardless of whether enforceability is considered in a proceeding in equity or at law.

C.    We express no opinion regarding the effectiveness of (i) any waiver (whether or not stated as such) under the Financing Documents of, or any consent thereunder relating to, unknown future rights or the rights of any party thereto existing, or duties owing to it, as a matter of law; (ii) any waiver (whether or not stated as such) contained in the Financing Documents of rights of any party, or duties owing to it, that is broadly or vaguely stated or does not describe the

right or duty purportedly waived with reasonable specificity; (iii) provisions relating to indemnification, exculpation or contribution, to the extent such provisions may be held unenforceable as contrary to public policy or federal or state securities laws or due to the negligence or willful misconduct of the indemnified party; (iv) any agreement to submit to the jurisdiction of any Federal Court; (v) any provision purporting to establish evidentiary standards; (vi) any provision to the effect that every right or remedy is cumulative and may be exercised in addition to any other right or remedy or that the election of some particular remedy does not preclude recourse to one or more others; or (vii) any right of setoff to the extent asserted by a participant in the rights of a Lender under the Financing Documents. In addition, we advise you that some of the provisions of the Financing Documents may not be enforceable by a Lender acting individually (as opposed to the Lenders acting through the Administrative Agent).

This opinion is rendered as of the date hereof to the Lender Parties in connection with the Financing Documents and may not be relied upon by any person other than the Lender Parties or by the Lender Parties in any other context. The Lender Parties may not furnish this opinion or copies hereof to any other person except (i) to bank examiners and other regulatory authorities should they so request in connection with their normal examinations, (ii) to the independent auditors and attorneys of the Lender Parties, (iii) pursuant to order or legal process of any court or governmental agency, (iv) in connection with any legal action to which any Lender Party is a party arising out of the transactions contemplated by the Financing Documents, or (v) to any potential permitted assignee of or participant in the interest of any Lender Party under the Financing Documents for its information. Notwithstanding the foregoing, (x) King & Spalding LLP, special counsel for the Administrative Agent, may rely on this opinion in connection with the opinion to be furnished by them in connection with the transactions contemplated by the Credit Agreement, and (y) parties referred to in clause (v) of the immediately preceding sentence who become Lenders after the date hereof may rely on this opinion as if it were addressed to them (provided that such delivery shall not constitute a re-issue or reaffirmation of this opinion as of any date after the date hereof). This opinion may not be quoted without the prior written consent of this Firm.

We have acted as special New York counsel to Wells Fargo Bank, National Association, individually and as Administrative Agent, in connection with the preparation, execution and delivery of the Amended and Restated Credit Agreement, dated as of June 27, 2014 (the “Credit Agreement”), among Sierra Pacific Power Company (the “Borrower”), the Lenders and LC Issuing Banks named therein and Wells Fargo Bank, National Association, as Administrative Agent and as Swingline Lender. This opinion is furnished to you pursuant to Section 3.01(a)(vii) of the Credit Agreement. Unless otherwise indicated, terms defined in the Credit Agreement are used herein as therein defined.

In that connection, we have examined the following documents:

(1)    Counterparts of the Credit Agreement, executed by the Borrower, the Administrative Agent, the Swingline Lender, the Lenders and the LC Issuing Banks;

(2)    A form of the promissory notes issued by the Borrower on the date hereof for the benefit of each Lender that requested one pursuant to Section 2.10(d) of the Credit Agreement (collectively, the “Notes”); and

(3)    The other documents furnished by the Borrower pursuant to Section 3.01(a) of the Credit Agreement, including (without limitation) the opinion of Michael J. Eason, counsel for the Borrower, and the opinion of Gibson, Dunn & Crutcher LLP, special New York counsel for the Borrower (collectively, the “Opinions”).

In our examination of the documents referred to above, we have assumed the authenticity of all such documents submitted to us as originals, the genuineness of all signatures, the due authority of the parties executing such documents and the conformity to the originals of all such documents submitted to us as copies. We have also assumed that each of the Lenders, the LC Issuing Banks, the Swingline Lender and the Administrative Agent has duly executed and delivered, with all

necessary power and authority (corporate and otherwise), the Credit Agreement. We have further assumed that you have evaluated, and are satisfied with, the creditworthiness of the Borrower and the business and financial terms evidenced by the Loan Documents.

To the extent that our opinions expressed below involve conclusions as to matters governed by law other than the law of the State of New York and the Federal law of the United States, we have relied upon the Opinions and have assumed without independent investigation the correctness of the matters set forth therein, our opinions expressed below being subject to the assumptions, qualifications and limitations set forth in the Opinions. We note that we do not represent the Borrower and, accordingly, are not privy to the nature or character of its businesses. Accordingly, we have also assumed that the Borrower is subject only to statutes, rules, regulations, judgments, orders, and other requirements of law generally applicable to corporations doing business in the State of New York. As to matters of fact, we have relied solely upon the documents we have examined.

Based upon the foregoing, and subject to the qualifications set forth below, we are of the opinion that:

(i)    The Credit Agreement is, and each of the Notes when executed and delivered for value received will be, the legal, valid and binding obligation of the Borrower enforceable against the Borrower in accordance with their respective terms.

(ii)    While we have not independently considered the matters covered by the Opinions to the extent necessary to enable us to express the conclusions stated therein, the Opinions and the other documents referred to in item (3) above are substantially responsive to the corresponding requirements set forth in Section 3.01(a) of the Credit Agreement pursuant to which the same have been delivered.

Our opinions are subject to the following qualifications:

(a)    Our opinion in paragraph (i) above is subject to the effect of any applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or similar law affecting creditors’ rights generally.

(b)    Our opinion in paragraph (i) above is subject to the effect of general principles of equity, including (without limitation) concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law). Such principles of equity are of general obligation, and, in applying such principles, a court, among other things, might not allow a contracting party to exercise remedies in respect of a default deemed immaterial, or might decline to order an obligor to perform covenants.

(c)    We note further that, in addition to the application of equitable principles described above, courts have imposed an obligation on contracting parties to act reasonably and in good faith in the exercise of their contractual rights and remedies, and may also apply public policy considerations in limiting the right of parties seeking to obtain indemnification under circumstances where the conduct of such parties in the circumstances in question is determined to have constituted negligence.

(d)    We express no opinion herein as to (i) Section 8.05 of the Credit Agreement, (ii) the enforceability of provisions purporting to grant to a party conclusive rights of determination, (iii) the availability of specific performance or other equitable remedies, (iv) the enforceability of rights to indemnity under Federal or state securities laws and (v) the enforceability of waivers by parties of their respective rights and remedies under law.

(e)    In connection with any provision of the Credit Agreement or the Notes whereby the Borrower submits to the jurisdiction of any court of competent jurisdiction, we note the limitations of 28 U.S.C. §§ 1331 and 1332 on Federal court jurisdiction.

(f)    Our opinions expressed above are limited to the law of the State of New York and the Federal law of the United States, and we do not express any opinion herein concerning any other law. Without limiting the generality of the foregoing, we express no opinion as to the effect of the law of any jurisdiction other than the State of New York wherein any Lender may be located or wherein enforcement of the Credit Agreement or the Notes may be sought that limits the rates of interest legally chargeable or collectible.

This opinion letter speaks only as of the date hereof, and we expressly disclaim any responsibility to advise you of any development or circumstance, including changes of law or fact, that may occur after the date of this opinion letter that might affect the opinions expressed herein. This opinion letter is furnished to the addressees hereof solely in connection with the transactions contemplated by the Credit Agreement, is solely for the benefit of the addressees hereof and may not be relied upon by any other Person or for any other purpose without our prior written consent. Notwithstanding the foregoing, this opinion letter may be relied upon by any Person that becomes a Lender after the date hereof in accordance with the provisions of the Credit Agreement as if this opinion letter were addressed and delivered to such Person on the date hereof. Any such reliance must be actual and reasonable under the circumstances existing at the time such Person becomes a Lender, taking into account any changes in law or facts and any other developments known to or reasonably knowable by such Person at such time.

Reference is hereby made to the Amended and Restated Credit Agreement, dated as of June 27, 2014 (as further amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), among Sierra Pacific Power Company (the “Borrower”), the Lenders party thereto from time to time, Wells Fargo Bank, National Association, as Administrative Agent and as Swingline Lender, and the LC Issuing Banks party thereto from time to time.

The undersigned has furnished the Administrative Agent and the Borrower with a certificate of its non-U.S. Person status on IRS Form W-8BEN.
