 SECTION 2. AMOUNT AND TERMS OF REVOLVING COMMITMENTS 
 2.1 Revolving Commitments. 
 (a) Subject to the terms and conditions
hereof, each Lender severally agrees to make revolving credit loans (“Revolving Loans”) to the Borrower from time to time during the Revolving Commitment Period in an aggregate principal amount at any one time outstanding which,
when added to such Lender’s Revolving Percentage of the sum of (i) L/C Obligations then outstanding and (ii) the aggregate principal amount of Swingline Loans then outstanding, does not exceed the amount of such Lender’s
Revolving Commitment. During the Revolving Commitment Period the Borrower may use the Revolving Commitments by borrowing, prepaying the Revolving Loans in whole or in part, and reborrowing, all in accordance with the terms and conditions hereof. The
Revolving Loans may from time to time be LIBOR Rate Loans or Base Rate Loans, as determined by the Borrower and notified to the Administrative Agent in accordance with Sections 2.2 and 2.7. 

(b) The Borrower shall repay to each Lender its outstanding Revolving Loans on the Revolving Termination Date and shall repay such other
Revolving Loans so that the Total Revolving Extensions of Credit do not exceed the Total Revolving Commitments to be in effect thereafter. The Borrower may request that the Revolving Commitments be extended for additional one year periods by
providing not less than 65 days’ written notice to the Administrative Agent prior to February 18 of any year (each, a “Noticed Anniversary Date”). If a Lender agrees, in its individual and sole discretion, to extend its
Revolving Commitments (such Lender, an “Extending Lender”), it will notify the Administrative Agent, in writing, of its decision to do so and the maximum amount of Revolving Commitments it agrees to so extend no later than 20 days
prior to the applicable Noticed Anniversary Date, which notice shall be irrevocable. The Administrative Agent will notify the Borrower, in writing, of the Lenders’ decisions no later than 15 days prior to such Noticed Anniversary Date. The
Extending Lenders’ and the New Lenders’ (as defined below) Revolving Commitments and the Revolving Termination Date will be extended for an additional year from the then-applicable Revolving Termination Date; provided that
(i) more than 50% of the Total Revolving Commitments outstanding on the applicable Noticed Anniversary Date are extended or otherwise committed to by Extending Lenders and any New Lenders, (ii) no Default or Event of Default shall have
occurred and be continuing and (iii) the 

  
 17 









 
representations and warranties set forth in Section 3 hereof if not qualified as to materiality shall be true and correct in all material respects and all other representations and
warranties set forth in Section 3 hereof shall be true and correct, in each case on and as of such date with the same force and effect as if made on or as of such date (except for those representations and warranties or parts thereof
that, by their terms, expressly relate solely to a specific date, in which case such representations and warranties, if not qualified as to materiality, shall be true and correct in all material respects and all such other representations and
warranties shall be true and correct, in each case as of such specific date). No Lender shall be required to consent to any such extension request and any Lender that declines or does not respond to the Borrower’s request for commitment renewal
(a “Declining Lender”) will have its Revolving Commitments terminated on the then existing termination date (without regard to any renewals by other Lenders). The Borrower will have the right to accept commitments from third party
financial institutions acceptable to the Administrative Agent (the “New Lenders”) in an amount equal to the amount of the Revolving Commitments of any Declining Lenders; provided that the Extending Lenders will have the right
to increase their Revolving Commitments up to the amount of the Declining Lenders’ Revolving Commitments before the Borrower will be permitted to substitute any other financial institutions for the Declining Lenders. The Borrower may only
extend the Revolving Termination Date two times pursuant to this Section 2.1(b). 
 2.2 Procedure for Revolving
Loan Borrowing. The Borrower may borrow under the Revolving Commitments during the Revolving Commitment Period on any Business Day; provided that the Borrower shall give the Administrative Agent irrevocable notice (which notice must be
received by the Administrative Agent prior to 11:00 A.M., New York City time, (a) three Business Days prior to the requested Borrowing Date, in the case of LIBOR Rate Loans, or (b) on the requested Borrowing Date, in the case of Base Rate
Loans) (provided further that any such notice of a borrowing of Base Rate Loans to finance payments required by Section 2.3(j) may be given not later than 11:00 A.M., New York City time, on the date of the proposed
borrowing), specifying (i) the Type of Revolving Loans to be borrowed, (ii) the requested Borrowing Date and (iii) the amount of each such Type of Revolving Loan and, in the case of LIBOR Rate Loans, the respective lengths of the
initial Interest Period therefor. Any Revolving Loans made on the Closing Date may be Base Rate Loans or LIBOR Rate Loans (subject, in the case of LIBOR Rate Loans, to the receipt of a customary funding indemnity letter not less than three
(3) Business Days prior to the Closing Date). Each borrowing under the Revolving Commitments shall be in an amount equal to $1,000,000 or a whole multiple thereof (or, if the then aggregate Available Revolving Commitments are less than
$1,000,000, such lesser amount); provided that the Swingline Lender may request, on behalf of the Borrower, borrowings under the Revolving Commitments that are Base Rate Loans in other amounts pursuant to Section 2.19. Upon
receipt of any such notice from the Borrower, the Administrative Agent shall promptly notify each Lender thereof. Each Lender will make the amount of its Revolving Percentage of each borrowing available to the Administrative Agent for the account of
the Borrower at the Funding Office prior to 1:00 P.M., New York City time, on the Borrowing Date requested by the Borrower in funds immediately available to the Administrative Agent. Such borrowing will then be made available to the Borrower by the
Administrative Agent crediting the account of the Borrower on the books of such office with the aggregate of the amounts made available to the Administrative Agent by the Lenders and in like funds as received by the Administrative Agent. 

2.3 Letters of Credit. 
 (a) Subject to the terms and conditions hereof, each Issuing Lender, in reliance on the agreements of the other Lenders set forth in Section 2.3(g), agrees to issue letters of credit
(“Letters of Credit”) for the account of the Borrower on any Business Day during the period from and including the Closing Date to the date that is five Business Days prior to the Revolving Termination Date in such form as may be
approved from time to time by such Issuing Lender; provided that no Issuing Lender shall have any obligation to issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C Obligations


  
 18 









 
would exceed the L/C Commitment (or the L/C Obligations in respect of Letters of Credit issued by such Issuing Lender exceed its maximum L/C Commitment as set forth in the definition thereof),
(ii) the Total Revolving Extensions of Credit would exceed the Total Revolving Commitments or (iii) any Lender is a Defaulting Lender, unless such Issuing Lender has entered into arrangements, including the delivery of Cash Collateral,
satisfactory to such Issuing Lender (in its sole discretion) with the Borrower or such Lender to eliminate such Issuing Lender’s actual or potential Fronting Exposure (after giving effect to Section 2.20(a)(iii)) with respect to
such Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other L/C Obligations as to which such Issuing Lender has actual or potential Fronting Exposure. Each Letter of Credit shall
(i) be denominated in Dollars and (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date that is five Business Days prior to the Revolving Termination Date; provided
that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods as set forth in Section 2.3(d) (which shall in no event extend beyond the date referred to in clause (y) above);
provided further that at any time the Revolving Commitments have been extended pursuant to Section 2.1(b), the L/C Obligations shall not exceed the Total Revolving Commitments scheduled to be in effect through the end of any
extended Revolving Commitment Period. 
 (b) No Issuing Lender shall at any time be obligated to issue any Letter of Credit if
such issuance would conflict with, or cause such Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law. 
 (c) The Borrower may from time to time request that an Issuing Lender issue a Letter of Credit by delivering to such Issuing Lender at its address for notices specified herein an Application therefor,
completed to the satisfaction of such Issuing Lender, and such other certificates, documents and other papers and information as such Issuing Lender may request. Upon receipt of any Application, such Issuing Lender will process such Application and
the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall such Issuing
Lender be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of
such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by such Issuing Lender and the Borrower. Such Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof.
Such Issuing Lender shall promptly furnish to the Administrative Agent, which shall in turn promptly furnish to the Lenders, notice of the issuance of each Letter of Credit (including the amount thereof). 

(d) If the Borrower so requests in any applicable Application, an Issuing Lender may, in its sole discretion, agree to issue a Letter of
Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the Issuing Lender to prevent any such extension at least once in
each twelve-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such twelve-month period to be
agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by the applicable Issuing Lender, the Borrower shall not be required to make a specific request to such Issuing Lender for any such extension. Once an Auto-Extension
Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the Issuing Lender to permit the extension of such Letter of Credit at any time to an expiry date not later than the date that is five Business
Days prior to the Revolving Termination Date; provided, however, that an Issuing Lender shall not permit any such extension if such Issuing Lender (A) has determined that it would not be permitted, or would have no obligation, at
such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof or (B) has received notice (which may be by telephone or in writing) on or before the day that is


  
 19 









 
seven Business Days before the Non-Extension Notice Date from the Administrative Agent, any Lender or the Borrower, in each case, that one or more of the applicable conditions specified in
Section 4.2 is not then satisfied, and in each such case directing the Issuing Lender not to permit such extension. 

(e) The Borrower will pay a fee on all outstanding Letters of Credit (a “Letter of Credit Fee”) at a per annum rate
equal to the Applicable Margin then in effect with respect to LIBOR Rate Loans, shared among the Lenders in accordance with their respective Revolving Percentages and payable quarterly in arrears on each Fee Payment Date after the issuance date;
provided, however, any Letter of Credit Fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which neither the Borrower nor such Defaulting Lender has provided Cash Collateral
satisfactory to the applicable Issuing Lender (in its sole discretion) shall be payable, to the maximum extent permitted by applicable law, to the other Lenders in accordance with the upward adjustments in their respective Revolving Percentages
allocable to such Letter of Credit pursuant Section 2.20(a)(iii), with the balance of such fee, if any, payable to the applicable Issuing Lender for its own account; provided further that if the Borrower provides Cash Collateral
in respect of the Fronting Exposure of such Defaulting Lender, such fee shall not be payable by the Borrower or, if paid, shall be returned to the Borrower. In addition, the Borrower shall pay to each applicable Issuing Lender for its own account a
fronting fee for each Letter of Credit requested by the Borrower in such amount and at such times as may be set forth in a separate letter agreement between the Borrower and such Issuing Lender. 

(f) In addition to the foregoing fees, the Borrower shall pay or reimburse each Issuing Lender for such normal and customary costs and
expenses as are incurred or charged by such Issuing Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit. 
 (g) Each Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce such Issuing Lender to issue Letters of Credit, each L/C Participant irrevocably agrees to
accept and purchase and hereby accepts and purchases from such Issuing Lender, on the terms and conditions set forth below, for such L/C Participant’s own account and risk, an undivided interest equal to such L/C Participant’s Revolving
Percentage in such Issuing Lender’s obligations and rights under and in respect of each Letter of Credit issued by such Issuing Lender and the amount of each draft paid by such Issuing Lender thereunder. Each L/C Participant agrees with each
Issuing Lender that, if a draft is paid under any Letter of Credit for which such Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such L/C Participant shall pay to such Issuing Lender upon
demand at such Issuing Lender’s address for notices specified herein an amount equal to such L/C Participant’s Revolving Percentage of the amount of such draft, or any part thereof, that is not so reimbursed (the “Unreimbursed
Amount”), and such amount equal to such L/C Participant’s Revolving Percentage of the amount of such draft shall be deemed to be a Base Rate Loan for all purposes hereunder. With respect to any Unreimbursed Amount that is not fully
refinanced by a borrowing of Base Rate Loans because the conditions set forth in Section 4.2 cannot be satisfied or for any other reason, each Lender shall pay to the Administrative Agent for the account of such Issuing Lender its
Revolving Percentage of such Unreimbursed Amount which shall be deemed payment in respect of its participation obligation under this Section 2.3(g). Each L/C Participant’s obligations to make the Revolving Loans referred to in this
Section 2.3(g) and to purchase participating interests pursuant to this Section 2.3(g) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim,
recoupment, defense or other right that such L/C Participant may have against such Issuing Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of a Default or an Event of Default or the failure
to satisfy any of the other conditions specified in Section 4, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower,
any other Loan Party or any other L/C Participant or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. 

  
 20 









 (h) If any amount required to be paid by any L/C Participant to any Issuing Lender pursuant
to Section 2.3(g) in respect of any unreimbursed portion of any payment made by such Issuing Lender under any Letter of Credit is paid to such Issuing Lender within three Business Days after the date such payment is due, such L/C
Participant shall pay to such Issuing Lender on demand an amount equal to the product of (i) such amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such payment is
required to the date on which such payment is immediately available to such Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any
such amount required to be paid by any L/C Participant pursuant to Section 2.3(g) is not made available to the applicable Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, such Issuing
Lender shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to Base Rate Loans. A certificate of an Issuing Lender submitted to any L/C
Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error. 
 (i)
Whenever, at any time after any Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its Revolving Percentage of such payment in accordance with Section 2.3(g), such Issuing Lender receives
any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by such Issuing Lender), or any payment of interest on account thereof, such Issuing Lender will
distribute to such L/C Participant its Revolving Percentage thereof; provided, however, that in the event that any such payment received by such Issuing Lender shall be required to be returned by such Issuing Lender, such L/C
Participant shall return to such Issuing Lender the portion thereof previously distributed by such Issuing Lender to it. 
 (j)
If any draft is paid under any Letter of Credit, the Borrower shall reimburse the applicable Issuing Lender for the amount of (a) the draft so paid and (b) any taxes, fees, charges or other costs or expenses incurred by such Issuing Lender
in connection with such payment, not later than 12:00 Noon, New York City time, on the Business Day immediately following the day that the Borrower receives notice of such draft, either directly or through the incurrence of a Revolving Loan pursuant
to Section 2.3(g). Each such payment shall be made to such Issuing Lender at its address for notices referred to herein in Dollars and in immediately available funds. Interest shall be payable on any such amounts from the date on which
the relevant draft is paid until payment in full at the rate set forth in Section 2.9(b). 
 (k) The Borrower’s
obligations under this Section 2.3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against any Issuing Lender,
any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees with each Issuing Lender that such Issuing Lender shall not be responsible for, and the Borrower’s Reimbursement Obligations under Section 2.3(j)
shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower
and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. No Issuing Lender
shall be liable for 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, except for errors or omissions found by a final and
nonappealable decision of a court of competent jurisdiction to have resulted from the gross 

  
 21 









 
negligence or willful misconduct of such Issuing Lender. The Borrower agrees that any action taken or omitted by an Issuing Lender under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful misconduct, shall be binding on the Borrower and shall not result in any liability of such Issuing Lender to the Borrower. 

(l) If any draft shall be presented for payment under any Letter of Credit, the applicable Issuing Lender shall promptly notify the
Borrower of the date and amount thereof. The responsibility of each Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in
such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are substantially in conformity with such Letter of Credit. 

(m) To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this
Section 2.3, the provisions of this Section 2.3 shall apply. 
 (n) Unless otherwise expressly agreed by
the applicable Issuing Lender and the Borrower when a Letter of Credit is issued, (i) the rules of the International Standby Practices shall apply to each standby Letter of Credit and (ii) the rules of the Uniform Customs and Practice for
Documentary Credits, as most recently published by the International Chamber of Commerce at the time of issuance, shall apply to each commercial Letter of Credit. 
 2.4 Commitment Fees, etc. 
 (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Lender a commitment fee for the period from and including the date hereof to the last day of the Revolving Commitment Period, computed at the Applicable Margin on the average daily amount of the Available
Revolving Commitment of such Lender (determined without giving effect to the aggregate principal amount of Swingline Loans then outstanding) during the period for which payment is made, payable quarterly in arrears on each Fee Payment Date,
commencing on the first such date to occur after the date hereof; provided, however, that no commitment fee shall accrue on the Available Revolving Commitment of a Defaulting Lender during any period that such Lender shall be a
Defaulting Lender. 
 (b) The Borrower agrees to pay to the Administrative Agent the fees in the amounts and on the dates
previously agreed to in writing by the Borrower and the Administrative Agent. 
 2.5 Termination or Reduction of Revolving
Commitments. The Borrower shall have the right, upon not less than three Business Days’ notice to the Administrative Agent, to terminate the Revolving Commitments or, from time to time, to reduce the amount of the Revolving Commitments;
provided that no such termination or reduction of Revolving Commitments shall be permitted if, after giving effect thereto and to any prepayments of the Revolving Loans and Swingline Loans made on the effective date thereof, the Total
Revolving Extensions of Credit would exceed the Total Revolving Commitments. Any such reduction shall be in an amount equal to any whole multiple of $1,000,000. 
 2.6 Optional Prepayments. The Borrower may at any time and from time to time prepay the Revolving Loans and Swingline Loans, in whole or in part, without premium or penalty, upon irrevocable notice
delivered to the Administrative Agent (or, with respect to Swingline Loans, the Swingline Lender) no later than 11:00 A.M., New York City time, three Business Days prior thereto in the case of LIBOR Rate Loans, no later than 11:00 A.M., New York
City time, on the Business Day thereof in the case of Base Rate Loans, and no later than 1:00 P.M., New York City time, on the Business Day thereof in the case of Swingline Loans, which notice shall specify the date and amount of


  
 22 









 
prepayment and whether the prepayment is of LIBOR Rate Loans, Base Rate Loans or Swingline Loans; provided that if a LIBOR Rate Loan is prepaid on any day other than the last day of the
Interest Period applicable thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.15. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. If any such notice
is given, the amount specified in such notice shall be due and payable on the date specified therein, together with (except in the case of Base Rate Loans and Swingline Loans) accrued interest to such date on the amount prepaid. Partial prepayments
of Revolving Loans shall be in an aggregate principal amount of $1,000,000 or a whole multiple thereof. Partial prepayments of Swingline Loans shall be in an aggregate principal amount of $100,000 or a whole multiple thereof. Each prepayment of the
Revolving Loans made pursuant to this Section 2.6 shall be applied ratably among the Lenders holding the Revolving Loans being prepaid, in proportion to the principal amount held by each; provided that if any Lender is a
Defaulting Lender at the time of any such prepayment, any optional prepayment of the Revolving Loans shall, if the Administrative Agent so directs at the time of such optional prepayment, be applied in accordance with
Section 2.20(a)(ii). 
 2.7 Conversion and Continuation Options. 

(a) The Borrower may elect from time to time to convert LIBOR Rate Loans to Base Rate Loans by giving the Administrative Agent prior
irrevocable notice of such election no later than 11:00 A.M., New York City time, on the Business Day of the proposed conversion; provided that any such conversion of LIBOR Rate Loans may only be made on the last day of an Interest Period
with respect thereto. The Borrower may elect from time to time to convert Base Rate Loans to LIBOR Rate Loans by giving the Administrative Agent prior irrevocable notice of such election no later than 11:00 A.M., New York City time, on the third
Business Day preceding the proposed conversion date (which notice shall specify the length of the initial Interest Period therefor); provided that no Base Rate Loan may be converted into a LIBOR Rate Loan when any Event of Default has
occurred and is continuing and the Administrative Agent or the Required Lenders have determined in its or their sole discretion not to permit such conversion. Upon receipt of any such notice the Administrative Agent shall promptly notify each
relevant Lender thereof. 
 (b) Any LIBOR Rate Loan may be continued as such upon the expiration of the then current Interest
Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next
Interest Period to be applicable to such Revolving Loans; provided that no LIBOR Rate Loan may be continued as such when any Event of Default has occurred and is continuing and the Administrative Agent has, on the direction of the Required
Lenders and upon notice to the Borrower, determined not to permit such continuations; provided further that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted
pursuant to the preceding proviso such Revolving Loans shall be automatically converted to Base Rate Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each
relevant Lender thereof. 
 2.8 Limitations on LIBOR Tranches. Notwithstanding anything to the contrary in this
Agreement, all borrowings, conversions and continuations of LIBOR Rate Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate
principal amount of the LIBOR Rate Loans comprising each LIBOR Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (b) no more than 20 LIBOR Tranches shall be outstanding at any one time. 

  
 23 









 2.9 Interest Rates and Payment Dates. 

(a) Each LIBOR Rate Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to
the LIBOR Rate determined for such day plus the Applicable Margin. Each LIBOR Rate Swingline Loan shall bear interest at a rate per annum equal to the LIBOR Market Index Rate plus the Applicable Margin for LIBOR Rate Loans. 

(b) Each Base Rate Loan shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin. Each Base Rate
Swingline Loan shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin for Base Rate Loans. 
 (c) (i) If all or a portion of the principal amount of any Revolving Loan or Reimbursement Obligation shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such
overdue amount shall bear interest at a rate per annum equal to the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2%, and (ii) if all or a portion of any interest payable on any
Revolving Loan or Reimbursement Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum
equal to the rate then applicable to Base Rate Loans plus 2%, in each case, with respect to clauses (i) and (ii) above, from the date of such non-payment until such amount is paid in full (as well after as before judgment).

 (d) Interest shall be payable in arrears on each Interest Payment Date; provided that interest accruing pursuant to
paragraph (c) of this Section shall be payable from time to time on demand. 
 2.10 Computation of Interest and
Fees. 
 (a) Interest and fees payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual
days elapsed, except that with respect to (i) any commitment fee, (ii) Base Rate Loans the rate of interest on which is calculated on the basis of the Prime Rate and (iii) Swingline Loans the rate of interest on which is calculated on
the basis of the Prime Rate, in each case such commitment fee or such interest shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable
notify the Borrower and the Lenders of each determination of a LIBOR Rate. Any change in the interest rate on a Revolving Loan resulting from a change in the Base Rate or the Reserve Requirements shall become effective as of the opening of business
on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of the effective date and the amount of each such change in interest rate. 

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive
and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining
any interest rate pursuant to Section 2.9(a). 
 2.11 Inability to Determine Interest Rate. If prior to the
first day of any Interest Period: 
 (a) the Administrative Agent shall have determined (which determination shall be conclusive
and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the LIBOR Rate for such Interest Period, or 

  
 24 









 (b) the Administrative Agent shall have received notice from the Required Lenders that the
LIBOR Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Revolving Loans during such
Interest Period, 
 the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the Lenders as soon as
practicable thereafter. If such notice is given (x) any LIBOR Rate Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (y) any Revolving Loans that were to have been converted on the first
day of such Interest Period to LIBOR Rate Loans shall be continued as Base Rate Loans and (z) any outstanding LIBOR Rate Loans shall be converted, on the last day of the then-current Interest Period, to Base Rate Loans. Until such notice has
been withdrawn by the Administrative Agent, no further LIBOR Rate Loans shall be made or continued as such, nor shall the Borrower have the right to convert Revolving Loans to LIBOR Rate Loans, nor shall any LIBOR Rate Swingline Loans be made.

 2.12 Pro Rata Treatment and Payments. 
 (a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Revolving Commitments of the Lenders shall be made
pro rata according to the respective Revolving Percentages of the Lenders. 
 (b) Each payment (including each
prepayment) by the Borrower on account of principal of and interest on the Revolving Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Loans then held by the Lenders. 

(c) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Funding Office, in Dollars and in
immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the LIBOR Rate Loans) becomes due and payable on a
day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a LIBOR Rate Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment
of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension. 
 (d) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing
available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the
Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at
a rate equal to the greater of (i) the Federal Funds Effective Rate and (ii) a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, for the period until such Lender makes such
amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such
Lender’s share of such 

  
 25 









 
borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such
amount with interest thereon at the rate per annum applicable to Base Rate Loans, on demand, from the Borrower. 
 (e) Unless
the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent
may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding
amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made
available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any
Lender against the Borrower. 
 2.13 Requirements of Law. 

(a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any
Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof (including all requests, rules, guidelines and directives in connection with the
Dodd-Frank Wall Street Reform and Consumer Protection Act regardless of the date enacted, adopted or issued): 

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any
Application or any LIBOR Rate Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.14 and changes in the rate of tax on the overall net income
of such Lender); 
 (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or
similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in
the determination of the LIBOR Rate; or 
 (iii) shall impose on such Lender any other condition; 

and the result of any of the foregoing is to increase the cost to such Lender, by an amount that such Lender deems to be material, of making, converting
into, continuing or maintaining LIBOR Rate Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand,
any additional amounts necessary to compensate such Lender on an after-tax basis for such increased cost or reduced amount receivable. Upon any Lender becoming aware that it is entitled to claim any additional amounts pursuant to this paragraph, it
shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled. 
 (b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender
or any corporation controlling such Lender with any request or directive 

  
 26 









 
regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof (including all requests, rules, guidelines and directives in
connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act regardless of the date enacted, adopted or issued) shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a
consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such
Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent)
of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation on an after-tax basis for such reduction; provided that the Borrower shall not be
required to compensate a Lender pursuant to this paragraph for any amounts incurred more than six months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; provided further
that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect. 
 (c) A certificate as to any additional amounts payable pursuant to this Section submitted in good faith by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the
absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder. 

2.14 Taxes. 
 (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority (collectively “Taxes”), excluding (i) net income Taxes and
franchise Taxes (imposed in lieu of net income Taxes) imposed on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority
imposing such Tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a
payment under, or enforced, this Agreement or any other Loan Document), (ii) Taxes attributable to the Administrative Agent or any Lender’s failure to comply with the requirements of Section 2.14(d) or 2.14(e),
(iii) any branch profits Taxes imposed by the United States or any similar Tax imposed by any other jurisdiction in which the Borrower is located, (iv) in the case of a payment to a Lender, United States withholding Taxes imposed on
amounts payable to such Lender at the time such Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts pursuant to this
paragraph or (v) any Tax to the extent imposed as a result of the Administrative Agent’s or any Lender’s (A) failure to comply with the applicable requirements of FATCA in such a way to reduce such tax to zero or
(B) election under Section 1471(b)(3) of the Code (all Taxes not excluded by clauses (i) through (v), “Non-Excluded Taxes”). If any Non-Excluded Taxes or Other Taxes are required to be withheld from any amounts
payable to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all
Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement. 

  
 27 









 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law. 
 (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower,
as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original official receipt received by the Borrower
showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the
Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure, except to the extent such amounts
are found by a final and nonappealable decision of a court of competent jurisdiction to have become payable as a result of the gross negligence or willful misconduct of the Administrative Agent or such Lender. 

(d) Each Lender (or Transferee) that is not a “U.S. Person” as defined in Section 7701(a)(30) of the Code (a
“Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal
Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a
statement substantially in the form of Exhibit C and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a
reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in
the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by
such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by
the U.S. taxing authorities for such purpose). In addition, each Non-U.S. Lender shall deliver to the Borrower and the Administrative Agent such other tax forms or other documents as shall be prescribed by applicable law, to the extent applicable,
(x) to demonstrate that payments to such Lender under this Agreement and the other Loan Documents are exempt from any United States federal withholding tax imposed pursuant to FATCA or (y) to allow the Borrower and the Administrative Agent
to determine the amount to deduct or withhold under FATCA from a payment hereunder. Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S.
Lender is not legally able to deliver. 
 (e) A Lender that is entitled to an exemption from or reduction of non-U.S.
withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative
Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a
reduced rate; provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s judgment such completion, execution or submission would not materially prejudice the legal position of
such Lender. 

  
 28 









 (f) If any Lender or the Administrative Agent determines, in its sole discretion, that it
has received a refund in respect of any Non-Excluded Taxes or Other Taxes as to which indemnification or additional amounts have been paid to it by the Borrower or KGE pursuant to this Section 2.14, it shall promptly remit such refund
(but only to the extent of indemnity payments made, or additional amounts paid, under this Section with respect to the Non-Excluded Taxes or Other Taxes giving rise to such refund) to the Borrower or KGE (as appropriate), net of all out-of-pocket
expenses of such Lender or Administrative Agent, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund net of any Taxes payable by such Lender or Administrative
Agent on such interest); provided that the Borrower or KGE (as appropriate), upon the request of the Lender or Administrative Agent, as the case may be, agree promptly to return such refund (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) to such party in the event such party is required to repay such refund to the relevant Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to
make available its tax returns (or any other information relating to Taxes that it deems confidential) to the Borrower or any other person. 
 (g) The agreements in this Section shall survive the termination of this Agreement and the payment of the Revolving Loans and all other amounts payable hereunder. 

2.15 Indemnity. The Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or expense that
such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of LIBOR Rate Loans after the Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any prepayment of or conversion from LIBOR Rate Loans after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making
of a prepayment of LIBOR Rate Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on
the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow,
convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Revolving Loans provided for herein (excluding, however, the Applicable Margin included therein,
if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank
eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted in good faith to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this
Agreement and the payment of the Revolving Loans and all other amounts payable hereunder. 
 2.16 Change of Lending
Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.13 or Section 2.14(a) with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts
(subject to overall policy considerations of such Lender) to designate another lending office for any Revolving Loans affected by such event with the object of avoiding the consequences of such event; provided that such designation is made on
terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage; provided further that nothing in this Section shall affect or postpone any of the
obligations of the Borrower or the rights of any Lender pursuant to Section 2.13 or Section 2.14(a). 

2.17 Replacement of Lenders. The Borrower shall be permitted to replace any Lender that (a) requests reimbursement for
amounts owing pursuant to Section 2.13 or Section 2.14(a) or (b) becomes a Defaulting Lender, with a replacement financial institution; provided that (i) such


  
 29 









 
replacement does not conflict with any Requirement of Law, (ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) prior to any such
replacement, such Lender shall have taken no action under Section 2.16 so as to eliminate the continued need for payment of amounts owing pursuant to Section 2.13 or Section 2.14(a), (iv) the replacement
financial institution shall purchase, at par, all Revolving Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (v) the Borrower shall be liable to such replaced Lender under Section 2.15 if
any LIBOR Rate Loan owing to such replaced Lender shall be purchased other than on the last day of the Interest Period relating thereto, (vi) the replacement financial institution, if not already a Lender, shall be reasonably satisfactory to
the Administrative Agent, (vii) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 9.6 (provided that the Borrower shall be obligated to pay the registration and
processing fee referred to therein), (viii) until such time as such replacement shall be consummated, the Borrower shall pay all additional amounts (if any) required pursuant to Section 2.13 or Section 2.14(a), as the
case may be, (ix) any such replacement shall not be deemed to be a waiver of any rights that the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender and (x) to the extent the replacement results
from a claim for compensation under Section 2.13 or Section 2.14, such replacement will result in a reduction in such compensation or payments thereunder. 

2.18 Swingline Commitment. 
 (a) Subject to the terms and conditions hereof, the Swingline Lender agrees to make a portion of the credit otherwise available to the Borrower under the Revolving Commitments from time to time during the
Revolving Commitment Period by making swing line loans (“Swingline Loans”) to the Borrower; provided that (i) the aggregate principal amount of Swingline Loans outstanding at any time shall not exceed the Swingline
Commitment then in effect (notwithstanding that the Swingline Loans outstanding at any time, when aggregated with the Swingline Lender’s other outstanding Revolving Loans, may exceed the Swingline Commitment then in effect) and (ii) the
Borrower shall not request, and the Swingline Lender shall not make, any Swingline Loan if, after giving effect to the making of such Swingline Loan, the Total Revolving Extensions of Credit would exceed the Total Revolving Commitments; provided
further that the Swingline Lender shall not be required to make a Swingline Loan (i) to refinance an outstanding Swingline Loan or (ii) if any Lender is at that time a Defaulting Lender, unless the Swingline Lender has entered into
arrangements, including the delivery of Cash Collateral, satisfactory to the Swingline Lender (in its sole discretion) with the Borrower or such Lender to eliminate the Swingline Lender’s actual or potential Fronting Exposure (after giving
effect to Section 2.20(a)(iii)) with respect to the Defaulting Lender arising from either, in its sole discretion, (a) the Swingline Loan then proposed to be made or (b) the Swingline Loan then proposed to be made and all other
Swingline Loans as to which the Swingline Lender has actual or potential Front Exposure. During the Revolving Commitment Period, the Borrower may use the Swingline Commitment by borrowing, repaying and reborrowing, all in accordance with the terms
and conditions hereof. A Swingline Loan shall bear interest at either (x) a rate based on the Base Rate (such Swingline Loan to be a “Base Rate Swingline Loan”) or (y) a rate based on the LIBOR Market Index Rate (such
Swingline Loan to be a “LIBOR Rate Swingline Loan”), as determined by the Borrower. 
 (b) The Borrower shall
repay to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Revolving Termination Date and the date that is fourteen days (subject to the provisions of Section 2.12(c)) after such Swingline Loan
is made. 
 2.19 Procedure for Swingline Borrowing; Refunding of Swingline Loans. 

(a) Whenever the Borrower desires that the Swingline Lender make Swingline Loans it shall give the Swingline Lender irrevocable
telephonic notice confirmed promptly in writing (which 

  
 30 









 
telephonic notice must be received by the Swingline Lender not later than 3:00 P.M., New York City time, on the proposed Borrowing Date), specifying (i) the amount to be borrowed,
(ii) the requested Borrowing Date (which shall be a Business Day during the Revolving Commitment Period) and (iii) the Type of Swingline Loans requested. Each borrowing under the Swingline Commitment shall be in an amount equal to $500,000
or a whole multiple of $100,000 in excess thereof. Not later than 4:00 P.M., New York City time, on the Borrowing Date specified in a notice in respect of Swingline Loans, the Swingline Lender shall make available to the Administrative Agent at the
Funding Office an amount in immediately available funds equal to the amount of the Swingline Loan to be made by the Swingline Lender. The Administrative Agent shall make the proceeds of such Swingline Loan available to the Borrower on such Borrowing
Date by depositing such proceeds in the account of the Borrower with the Administrative Agent on such Borrowing Date in immediately available funds. Immediately upon the making of a Swingline Loan, each Lender shall be deemed to, and hereby
irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan in an amount equal to the product of such Lender’s Revolving Percentage times the amount of such Swingline Loan.

 (b) The Swingline Lender, at any time and from time to time in its sole and absolute discretion may, on behalf of the
Borrower (which hereby irrevocably directs the Swingline Lender to act on its behalf), on one Business Day’s notice given by the Swingline Lender no later than 12:00 Noon, New York City time, request each Revolving Lender to make, and each
Revolving Lender hereby agrees to make, a Revolving Loan, in an amount equal to such Revolving Lender’s Revolving Percentage of the aggregate amount of the Swingline Loans (the “Refunded Swingline Loans”) outstanding on the
date of such notice, to repay the Swingline Lender. Each Revolving Lender shall make the amount of such Revolving Loan available to the Administrative Agent at the Funding Office in immediately available funds, not later than 10:00 A.M., New York
City time, one Business Day after the date of such notice. The proceeds of such Revolving Loans shall be immediately made available by the Administrative Agent to the Swingline Lender for application by the Swingline Lender to the repayment of the
Refunded Swingline Loans. Revolving Loans made pursuant to this Section 2.19(b) shall be Base Rate Loans except as otherwise agreed by the Borrower. 
 (c) If prior to the time a Revolving Loan would have otherwise been made pursuant to Section 2.19(b), one of the events described in Section 7(f) shall have occurred and be
continuing with respect to the Borrower or if for any other reason, as determined by the Swingline Lender in its sole discretion, Revolving Loans may not be made as contemplated by Section 2.19(b), each Revolving Lender shall, on the
date such Revolving Loan was to have been made pursuant to the notice referred to in Section 2.19(b), purchase for cash an undivided participating interest in the then outstanding Swingline Loans by paying to the Swingline Lender an
amount (the “Swingline Participation Amount”) equal to (i) such Revolving Lender’s Revolving Percentage times (ii) the sum of the aggregate principal amount of Swingline Loans then outstanding that were to have
been repaid with such Revolving Loans. 
 (d) Whenever, at any time after the Swingline Lender has received from any Revolving
Lender such Lender’s Swingline Participation Amount, the Swingline Lender receives any payment on account of the Swingline Loans, the Swingline Lender will distribute to such Lender its Swingline Participation Amount (appropriately adjusted, in
the case of interest payments, to reflect the period of time during which such Lender’s participating interest was outstanding and funded and, in the case of principal and interest payments, to reflect such Lender’s pro rata
portion of such payment if such payment is not sufficient to pay the principal of and interest on all Swingline Loans then due); provided, however, that in the event that any portion of such payment received by the Swingline Lender is
required to be returned, such Revolving Lender will return to the Swingline Lender any portion thereof previously distributed to it by the Swingline Lender. 

  
 31 









 (e) Each Revolving Lender’s obligations to make the Revolving Loans referred to in
Section 2.19(b) and to purchase participating interests pursuant to Section 2.19(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment,
defense or other right that such Revolving Lender or the Borrower may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of a Default or an Event of Default or the
failure to satisfy any of the other conditions specified in Section 4, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the
Borrower, any other Loan Party or any other Revolving Lender or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. 
 2.20 Defaulting Lenders. 
 (a) 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) 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 9.1. 

(ii) 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 Section 7 or otherwise) shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of
any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Lenders or the Swingline Lender
hereunder; third, if so determined by the Administrative Agent or requested by the Issuing Lenders or the Swingline Lender, to be held as Cash Collateral for future funding obligations of such Defaulting Lender in respect of any participation
in or refunding of any Letter of Credit or Swingline Loan; fourth, as the Borrower may request (so long as no Default exists), to the funding of any Revolving Loan in respect of which that 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 non-interest bearing deposit account and released in order to satisfy
obligations of such Defaulting Lender to fund Revolving Loans under this Agreement; sixth, to the payment of any amounts owing to the Lenders, the Issuing Lenders or the Swingline Lender as a result of any judgment of a court of competent
jurisdiction obtained by any Lender, any Issuing Lender or the Swingline Lender against that 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 Revolving Loans or any L/C Exposure
in respect of which such Defaulting Lender has not fully funded its appropriate share and (y) such Revolving Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 3.4 were
satisfied or waived, such payment shall be applied solely to pay the Revolving Loans of, and 

  
 32 









 
obligations in respect of Letters of Credit owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Revolving Loans of, or obligations
in respect of Letters of Credit owed to, such Defaulting Lender. 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 shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto. 
 (iii) All or any part of such Defaulting Lender’s L/C Exposure and its Swingline Exposure shall automatically (effective on the day such Lender becomes a Defaulting Lender) be reallocated among the
non-Defaulting Lenders in accordance with their respective Revolving Percentages (calculated without regard to such Defaulting Lender’s Revolving Commitment) but only to the extent that (x) no Default shall have occurred and be continuing
(and, unless the Borrower shall have otherwise notified the Administrative Agent at the time, the Borrower shall be deemed to have represented and warranted that such condition is satisfied at such time) and (y) such reallocation does not cause
the Revolving Extensions of Credit of any non-Defaulting Lender to exceed such non-Defaulting Lender’s Revolving Commitment. 
 (iv) If the reallocation described in clause (iii) 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, within two Business Days following notice by the Administrative Agent, Cash Collateralize such Defaulting Lender’s L/C Exposure and its Swingline Exposure (after giving effect to any partial reallocation pursuant to clause (iii)
above) in accordance with the procedures set forth in Section 2.20(c) for so long as such L/C Obligations or Swingline Loans are outstanding. 
 (b) If the Borrower, the Administrative Agent, the Issuing Lenders and the Swingline Lender agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting
Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral),
that Lender will, to the extent applicable, purchase that portion of outstanding Revolving Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Revolving Loans and funded and
unfunded participations in Letters of Credit and Swingline Loans to be held on a pro rata basis by the Lenders in accordance with their respective Revolving Credit Percentages (without giving effect to Section 2.20(a)(iii),
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;
provided further that except to the extent otherwise expressly agreed 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) At any time that there shall exist a Defaulting Lender, within two
Business Days upon the request of the Administrative Agent, any Issuing Lender or the Swingline Lender, the Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving
effect to Section 2.20(a)(iii) and any Cash Collateral provided by the Defaulting Lender). 
 (i) All
Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked deposit accounts with the 

  
 33 









 
Administrative Agent. The Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the
Administrative Agent, the Issuing Lenders and the Lenders (including the Swingline Lender), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as
collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to clause (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 as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby,
the Borrower or the relevant Defaulting Lender 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. 

(ii) Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under any of this
Section 2.20 in respect of Letters of Credit or Swingline Loans shall be held and applied to the satisfaction of the specific L/C Exposure or Swingline Exposure, obligations to fund participations therein (including, as to Cash
Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein. 

(iii) Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall
be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its
assignee)) or (ii) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, that the Person providing Cash Collateral and each applicable Issuing Lender or Swingline
Lender may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations. 
 2.21 Increase in Revolving Commitments. 
 (a) From time to time on and
after the Closing Date and prior to the Revolving Termination Date but not more than 2 times during any 12-month period, the Borrower may, upon at least 30 days notice to the Administrative Agent (which shall promptly provide a copy of such notice
to the Lenders), propose to increase the aggregate amount of the Revolving Commitments by an amount which (i) is not less than $10,000,000 or, if greater, an integral multiple of $1,000,000 in excess thereof, with respect to any such request,
and (ii) when aggregated with all prior and concurrent increases in the Revolving Commitments pursuant to this Section 2.21, is not in excess of $130,000,000; provided that at no time shall the Total Revolving Commitments
exceed $400,000,000. The Borrower may increase the aggregate amount of the Revolving Commitments by (x) having another lender or lenders (each, an “Additional Lender”) become party to this Agreement, (y) agreeing with any
Lender (with the consent of such Lender in its sole discretion) to increase its Revolving Commitment hereunder (each, an “Increasing Lender”) or (z) a combination of the procedures described in clauses (x) and (y) of
this sentence; provided that no Lender shall be obligated to increase its Revolving Commitment without its consent. 

  
 34 









 (b) Any increase in the Total Revolving Commitments pursuant to this
Section 2.21 shall be subject to the satisfaction of the following conditions: 
 (i) Each of the
representations and warranties contained in Section 3 and in the other Loan Documents shall be, if qualified as to materiality, true and correct and all other representations and warranties shall be true and correct in all material
respects, in each case on and as of such date of increase with the same effect as if made on and as of such date, both immediately before and after giving effect to such increase (except to the extent any such representation or warranty is expressly
stated to have been made as of a specific date, in which case such representation or warranty, if qualified as to materiality, shall be true and correct and all other such representations and warranties shall be true and correct in all material
respects, in each case as of such date); 
 (ii) At the time of such increase, no Default shall have occurred and
be continuing or would result from such increase; 
 (iii) The Borrower shall have delivered to the
Administrative Agent (x) a true and complete copy of the resolutions of the board of directors of the Borrower authorizing such increase and a certificate from a Responsible Officer certifying the effectiveness of such resolutions and
(y) such legal opinions covering such matters incident to the increase as the Administrative Agent may reasonably require; and 
 (iv) (x) Unless the Collateral shall have been released pursuant to Section 22(a) of the KGE Collateral Agreement and without prejudice to the Borrower’s or KGE’s right to require any
such release, the Collateral Agent shall have received the physical delivery of bonds in certificated form, registered in the name of the Collateral Agent and issued under either the Borrower Indenture or the KGE Indenture in a principal amount
equal to such increase and (y) the Security Documents shall have been amended as necessary in accordance with Section 3(e) of the KGE Collateral Agreement to treat such additional bonds as Pledged Bonds subject to the first priority lien
of the Collateral Agent, for the ratable benefit of the Secured Parties (as defined in the KGE Collateral Agreement). 
 (c)
Upon the effective date of any increase in the amount of the Total Revolving Commitments pursuant to this Section 2.21 (each, an “Additional Commitment”): 

(i) Each Additional Lender or Increasing Lender shall enter into a joinder agreement in form and substance reasonably
satisfactory to the Administrative Agent pursuant to which such Additional Lender or Increasing Lender shall, as of the effective date, undertake an Additional Commitment (or, in the case of an Increasing Lender, pursuant to which such Increasing
Lender’s Revolving Commitment shall be increased in the agreed amount on such date) and such Additional Lender shall thereupon become (or, if an Increasing Lender, continue to be) a “Lender” for all purposes hereof; and 

(ii) Each of the existing Lenders shall assign to each Person providing an Additional Commitment, and each such Person
shall purchase from each of the existing Lenders, Revolving Loans (together with accrued but unpaid interest thereon), in an amount as shall be necessary in order that, after giving effect to all such assignments and purchases, such Revolving Loans
will be held by existing Lenders and the Persons making the Additional Commitments ratably in accordance with their Revolving Percentages after giving effect to such Additional Commitments. 

(d) This Section 2.21 shall supersede any provisions in Section 9.1 to the contrary. Notwithstanding any other
provision of any Loan Document, the Loan Documents may be amended by the Administrative Agent and the Borrower, if necessary, to provide for terms applicable to each Additional Commitment.

 SECTION 3. REPRESENTATIONS AND WARRANTIES 

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Revolving Loans, issue or participate in
the Letters of Credit and make or participate in the Swingline Loans, the Borrower hereby represents and warrants to the Administrative Agent and each Lender that: 
 3.1 Financial Condition. The Borrower has heretofore furnished to the Lenders its consolidated balance sheets and statements of income and changes in financial position (or of cash flow, as the
case may be) as of and for the fiscal year ended December 31, 2009, audited by and accompanied by the opinion of Deloitte & Touche LLP. Such financial statements present fairly the financial condition and results of operations of the
Borrower and its consolidated Subsidiaries, as of such dates and for such periods. Such balance sheets and the notes thereto disclose all material liabilities, direct or contingent, of the Borrower and its consolidated Subsidiaries, as of the dates
thereof. Such financial statements were prepared in accordance with GAAP applied on a consistent basis (except as disclosed in the notes thereto). During the period from December 31, 2009, to and including the Closing Date, there has been no
Disposition by the Borrower or any Significant Subsidiary of any material part of its business or property other than as disclosed in the Exchange Act Documents. 
 3.2 No Change. Other than as disclosed in the Exchange Act Documents, since December 31, 2009, there has been no development or event that has had or could reasonably be expected to have a
Material Adverse Effect. 
 3.3 Existence; Compliance with Law. Each of the Borrower and the Significant Subsidiaries
(a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the power and authority, and the legal right, to own and operate its property and assets and to conduct the
business in which it is currently engaged, except to the extent the failure to have such power or authority would not result in a Material Adverse Effect, (c) is duly qualified as a foreign corporation and in good standing under the laws of
each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, except where the failure so to qualify or be in good standing would not result in a Material Adverse Effect, and
(d) is in compliance with all Requirements of Law except to the extent that the failure to comply therewith would not result in a Material Adverse Effect. 
 3.4 Power; Authorization; Enforceable Obligations. Each Loan Party has the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in
the case of the Borrower, to obtain extensions of credit hereunder. Each Loan Party has taken all necessary organizational action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of
the Borrower, to authorize the extensions of credit on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in
connection with the Transactions, the extensions of credit hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, other than (i) consents, authorizations, filings and
notices that have been obtained or made and are in full force and effect and (ii) the filings referred to in Section 3.19. Each Loan Document has been duly executed and delivered on behalf of each Loan Party party thereto. This
Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party party thereto, enforceable against each such Loan Party in accordance with its terms, except as
enforceability may be limited by applicable 

  
 36 









 
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought
by proceedings in equity or at law). 
 3.5 No Legal Bar. The execution, delivery and performance of this Agreement and
the other Loan Documents, the issuance of the Letters of Credit, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or any Contractual Obligation of any Loan Party and will not result in, or require,
the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents). No Requirement of Law or
Contractual Obligation applicable to the Borrower or any of its Subsidiaries could reasonably be expected to have a Material Adverse Effect. 
 3.6 Litigation. Except as set forth in the Exchange Act Documents, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge
of the Borrower, threatened by or against the Borrower or any Significant Subsidiary or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or
thereby or (b) as to which there is a reasonable possibility of an adverse determination and which, if adversely determined, could, individually or in the aggregate, result in a Material Adverse Effect. 

3.7 No Default. No Group Member is in default under or with respect to any of its Contractual Obligations in any respect that
could reasonably be expected to have a Material Adverse Effect. No Default or Event of Default has occurred and is continuing. 

3.8 Ownership of Property; Liens. Each of the Borrower and the Significant Subsidiaries has good title to, or valid leasehold
interests in, all its material properties and assets, except for defects in title that do not materially interfere with its ability to conduct its business as currently conducted or to utilize such properties and assets for their intended purposes
and that would not reasonably be expected to result in a Material Adverse Effect, and none of such property or assets is subject to any Lien except as permitted by Section 6.2. 

3.9 Intellectual Property. Except as, in the aggregate, could not reasonably be expected to have a Material Adverse Effect:
(a) each of the Borrower and the Significant Subsidiaries owns, or is licensed to use, all Intellectual Property necessary for the conduct of its business as currently conducted; (b) no claim has been asserted and is pending by any Person
challenging or questioning the use of any Intellectual Property or the validity or effectiveness of any Intellectual Property, nor does the Borrower know of any valid basis for any such claim; and (c) the use of Intellectual Property by each of
the Borrower and the Significant Subsidiaries does not infringe on the rights of any Person in any material respect. 
 3.10
Taxes. Each of the Borrower and the Significant Subsidiaries has filed or caused to be filed all material federal, state and other tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or
on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than, in each case, any the amount of which is currently being contested
in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or the relevant Significant Subsidiary); no material tax Lien has been filed, and, to the knowledge
of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge. 

  
 37 









 3.11 Federal Regulations. No part of the proceeds of any Revolving Loans, and no
other extensions of credit hereunder, will be used for “buying” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in
effect or for any purpose that violates the provisions of the Regulations of the Board. If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect
in conformity with the requirements of FR Form G-3 or FR Form U-1, as applicable, referred to in Regulation U. 
 3.12 Labor
Matters. Except as, in the aggregate, could not reasonably be expected to have a Material Adverse Effect: (a) there are no strikes or other labor disputes against any Group Member pending or, to the knowledge of the Borrower, threatened;
(b) hours worked by and payment made to employees of each Group Member have not been in violation of the Fair Labor Standards Act or any other applicable Requirement of Law dealing with such matters; and (c) all payments due from any Group
Member on account of employee health and welfare insurance have been paid or accrued as a liability on the books of the relevant Group Member. 
 3.13 ERISA. Except as, in the aggregate, could not reasonably expected to result in material liability to any Group Member, neither a Reportable Event nor any failure to meet the “minimum
funding standard” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred during the five-year period prior to the date on which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions of ERISA and the Code. No termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The
present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed
the value of the assets of such Plan allocable to such accrued benefits by a material amount. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could
reasonably be expected to result in a material liability under ERISA, and neither the Borrower nor any Commonly Controlled Entity would become subject to any material liability under ERISA if the Borrower or any such Commonly Controlled Entity were
to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent. 

3.14 Investment Company Act; Other Regulations. No Loan Party is an “investment company”, or a company
“controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended. 
 3.15 Subsidiaries. As of the Closing Date, Schedule 3.15 sets forth the name and jurisdiction of incorporation of each Subsidiary with assets of $25,000,000 or more and, as to each such
Subsidiary, the percentage of each class of Capital Stock owned by any Loan Party. KGE has no outstanding rights, warrants, options or convertible or exchangeable securities entitling the holders thereof, conditionally or unconditionally, to
purchase, subscribe for or otherwise receive shares of capital stock of KGE. 
 3.16 Use of Proceeds. The proceeds of the
Revolving Loans and the Swingline Loans, and the Letters of Credit, shall be used for general corporate purposes, including, but not limited to, repayment of any Indebtedness and to backstop the issuance of commercial paper. 

  
 38 









 3.17 Environmental Matters. Except as disclosed in the Exchange Act Documents or as,
in the aggregate, could not reasonably be expected to have a Material Adverse Effect: 
 (a) the facilities and properties
owned, leased or operated by the Borrower and the Significant Subsidiaries (the “Properties”) do not contain, and have not previously contained, any Materials of Environmental Concern in amounts or concentrations or under
circumstances that constitute or constituted a violation of, or could give rise to liability under, any Environmental Law; 

(b) neither the Borrower nor any Significant Subsidiary has received or is aware of any notice of violation, alleged violation,
non-compliance, liability or potential liability regarding environmental matters or compliance with Environmental Laws with regard to any of the Properties or the business operated by the Borrower and the Significant Subsidiaries (the
“Business”), nor does the Borrower have knowledge or reason to believe that any such notice will be received or is being threatened; 
 (c) Materials of Environmental Concern have not been transported or disposed of from the Properties in violation of, or in a manner or to a location that could give rise to liability under, any
Environmental Law, nor have any Materials of Environmental Concern been generated, treated, stored or disposed of at, on or under any of the Properties in violation of, or in a manner that could give rise to liability under, any applicable
Environmental Law; 
 (d) no judicial proceeding or governmental or administrative action is pending or, to the knowledge of the
Borrower, threatened, under any Environmental Law to which the Borrower or any Significant Subsidiary is or will be named as a party with respect to the Properties or the Business, nor are there any consent decrees or other decrees, consent orders,
administrative orders or other orders, or other administrative or judicial requirements outstanding under any Environmental Law with respect to the Properties or the Business; 
 (e) there has been no release or threat of release of Materials of Environmental Concern at or from the Properties, or arising from or related to the operations of the Borrower or any Significant
Subsidiary in connection with the Properties or otherwise in connection with the Business, in violation of or in amounts or in a manner that could give rise to liability under Environmental Laws; 

(f) the Properties and all operations at the Properties are in compliance, and have in the last five years been in compliance, with all
applicable Environmental Laws, and there is no contamination at, under or about the Properties or violation of any Environmental Law with respect to the Properties or the Business; and 

(g) neither the Borrower nor any Significant Subsidiary has assumed any liability of any other Person under Environmental Laws.

 3.18 Accuracy of Information, etc. The statements contained in this Agreement, any other Loan Document, the
Confidential Information Memorandum, the Exchange Act Documents or any other document, certificate or statement furnished or made available by or on behalf of any Loan Party to the Administrative Agent or the Lenders, or any of them, for use in
connection with the transactions contemplated by this Agreement or the other Loan Documents, taken as a whole, as of the date hereof do not (a) contain any untrue statement of a material fact or (b) omit to state a material fact necessary
to make the statements contained herein or therein not misleading in light of the circumstances under which such statements are or were made, in each case where such material misstatement or omission could adversely affect the rights or interests of
the Lenders; provided that, with respect to projected and pro forma financial information contained in the materials referenced above, the Borrower represents only that such information was prepared in good faith based upon assumptions
believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the


  
 39 









 
period or periods covered by such financial information may differ from the projected results set forth therein by a material amount. There is no fact known to any Loan Party that could
reasonably be expected to have a Material Adverse Effect that has not been expressly disclosed herein, in the other Loan Documents, in the Confidential Information Memorandum, in the Exchange Act Documents or in any other documents, certificates and
statements, taken as a whole, furnished to the Administrative Agent and the Lenders for use in connection with the transactions contemplated hereby and by the other Loan Documents. 

3.19 Security Documents. The KGE Collateral Agreement is effective to create in favor of the Collateral Agent thereunder, for the
benefit of the Lenders, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case of the Pledged Bonds described in the KGE Collateral Agreement, when certificates representing such
Pledged Bonds are delivered to the Collateral Agent, the KGE Collateral Agreement shall constitute a perfected first-priority Lien on, and security interest in, all right, title and interest of the Loan Parties in such Collateral and the proceeds
thereof, as security for the Obligations (as defined in the KGE Collateral Agreement).

 SECTION 8. THE AGENTS 

8.1 Appointment. Each Lender hereby irrevocably designates and appoints the Administrative Agent as the agent of such Lender under
this Agreement and the other Loan Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to
exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding
any provision to the contrary elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent. 

8.2 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents
by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys
in-fact selected by it with reasonable care. 
 8.3 Exculpatory Provisions. None of the Agents nor any of its respective
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except
to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any
manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other
Loan Document or for any failure of any Loan Party a party thereto to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any
of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party. 
 8.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent,
certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including counsel to the Borrower), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any note as the owner thereof for all
purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or
any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense that may be 

  
 52 









 
incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this
Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Revolving Loans.

deemed to have knowledge or notice of the occurrence of any Default or Event of Default unless the Administrative Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a “notice of default”. In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give notice thereof to the Lenders. The Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders); provided that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

 8.6 Non-Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that none of the Agents nor any of
their respective officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of a Loan Party or any
affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made
its own decision to make its Revolving Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise),
prospects or creditworthiness of any Loan Party or any affiliate of a Loan Party that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates. 

8.7 Indemnification. The Lenders agree to indemnify each Agent in its capacity as such (to the extent not reimbursed by the
Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is
sought after the date upon which the Revolving Commitments shall have terminated and the Revolving Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), from and against
any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Revolving Loans) be imposed on,
incurred by or asserted against such Agent in any way relating to or arising out of, the Revolving Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with 

  
 53 









 
any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the
payment of the Revolving Loans and all other amounts payable hereunder. 
 8.8 Agent in Its Individual Capacity. Each
Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Revolving Loans made or renewed by it and with respect to
any Letter of Credit issued or participated in by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms
“Lender” and “Lenders” shall include each Agent in its individual capacity. 
 8.9 Successor
Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 10 days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan
Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 7(a) or Section 7(f) with respect to the
Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the
Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be
terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Revolving Loans. If no successor agent has accepted appointment as Administrative
Agent by the date that is 10 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall assume and perform all
of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions
of this Section 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents. 

8.10 Syndication Agent and Documentation Agents. Neither the Syndication Agent nor any of the Documentation Agents shall have any
duties or responsibilities hereunder in its capacity as such. 
 SECTION 9. MISCELLANEOUS 

9.1 Amendments and Waivers. Neither this Agreement, any other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this Section 9.1 (other than any amendments to the Loan Documents contemplated by Section 3(e) of the KGE Collateral Agreement). The Required Lenders and each Loan
Party party to the relevant Loan Document may, or, with the written consent of the Required Lenders, the Administrative Agent and each Loan Party party to the relevant Loan Document may, from time to time, (a) enter into written amendments,
supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Loan Parties hereunder or
thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or


  
 54 









 
any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) forgive the principal
amount or extend the final scheduled date of maturity of any Revolving Loan, forgive any accrued but unpaid interest on any Revolving Loan or Reimbursement Obligation, reduce the stated rate of any interest or fee payable hereunder (except
(x) in connection with the waiver of applicability of any post-default increase in interest rates (which waiver shall be effective with the consent of the Required Lenders) and (y) that any amendment or modification of defined terms used
in the covenants in this Agreement shall not constitute a reduction in the rate of interest or fees for purposes of this clause (i)) or extend the scheduled date of any payment thereof, increase the amount of the Revolving Commitment of any
Lender, or extend the expiration date of any Lender’s Revolving Commitment, in each case without the written consent of each Lender directly affected thereby; (ii) eliminate or reduce the voting rights of any Lender under this
Section 9.1 without the written consent of such Lender; (iii) amend the definition of Required Lenders or Supermajority Lenders, amend this proviso to this Section 9.1, consent to the assignment or transfer by the
Borrower or KGE of any of its rights and obligations under this Agreement and the other Loan Documents, release all or substantially all of the Collateral (except pursuant to Section 22 of the KGE Collateral Agreement), or release KGE from its
guarantee under the KGE Collateral Agreement (except pursuant to Section 22 of the KGE Collateral Agreement), in each case without the written consent of all Lenders; (iv) amend, modify or waive any provision of Section 8
without the written consent of the Administrative Agent; (v) release any of the Collateral (except pursuant to Section 22 of the KGE Collateral Agreement), amend, modify or waive any provision of Section 6(e) of the KGE Collateral
Agreement, increase the amount specified in the definition of “Secured Agreement” in the KGE Collateral Agreement or amend the definition of “Release of Collateral Ratings Level” in the KGE Collateral Agreement, in each case
without the written consent of the Supermajority Lenders; (vi) amend, modify or waive any provision of Section 2.12(a) or (b) or Section 9.7(a) without the written consent of each Lender directly affected
thereby; (vii) amend, modify or waive any provision of Section 2.3 without the written consent of each Issuing Lender; or (viii) amend, modify or waive any provision of Section 2.18 or 2.19 without the
written consent of the Swingline Lender. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Administrative Agent and all future
holders of the Revolving Loans. In the case of any waiver, the Loan Parties, the Lenders and the Administrative Agent shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of
Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. 

For the avoidance of doubt, this Agreement may be amended (or amended and restated) with the written consent of the Required Lenders, the
Administrative Agent and the Borrower (a) to add one or more additional credit facilities to this Agreement and to permit the extensions of credit from time to time outstanding thereunder and the accrued interest and fees in respect thereof
(collectively, the “Additional Extensions of Credit”) to share ratably in the benefits of this Agreement and the other Loan Documents with the Revolving Loans and the accrued interest and fees in respect thereof and (b) to
include appropriately the Lenders holding such credit facilities in any determination of the Required Lenders and the Supermajority Lenders. 
 Notwithstanding anything to the contrary herein, (i) no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or
consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the applicable Lenders other than Defaulting Lenders), except that (x) the Revolving Commitment of any Defaulting Lender
may not be increased or extended without the consent of such Lender and (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than
other affected 

  
 55 









 
Lenders shall require the consent of such Defaulting Lender, and (ii) if the Administrative Agent and the Borrower shall have jointly identified (each in its sole discretion) an obvious
error or omission of a technical or immaterial nature, in each case, in any provision of the Loan Documents, then the Administrative Agent and the applicable Loan Parties shall be permitted to amend such provision and such amendment shall become
effective without any further action or consent of any other party to any Loan Document if the same is not objected to in writing by the Required Lenders within five Business Days following the posting of such amendment to the Lenders. 

9.2 Notices. All notices, requests and demands to or upon the respective parties hereto to be effective shall be in writing

 9.3 No Waiver;

 57 









 9.5 Payment of Expenses and Taxes. The Borrower agrees (a) to pay or reimburse
the Administrative Agent for all reasonable and documented or invoiced out-of-pocket costs and expenses incurred in connection with the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and
the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including the reasonable and documented or invoiced fees and
disbursements of one counsel (plus one firm of special regulatory counsel and one firm of local counsel per material jurisdiction as may reasonably be necessary), and filing and recording fees and expenses, with statements with respect to the
foregoing to be submitted to the Borrower prior to the Closing Date (in the case of amounts to be paid on the Closing Date) and from time to time thereafter on a quarterly basis or such other periodic basis as the Administrative Agent shall deem
appropriate, (b) to pay or reimburse each Lender and the Administrative Agent for all its costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any such
other documents, including the reasonable and documented or invoiced fees and disbursements of counsel to each Lender and of counsel to the Administrative Agent, (c) to pay, indemnify, and hold each Lender and the Administrative Agent harmless
from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, that may be payable or determined to be payable in connection with the execution
and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such
other documents, and (d) to pay, indemnify, and hold each Lender and the Administrative Agent and their respective officers, directors, employees, affiliates, agents and controlling persons (each, an “Indemnitee”) harmless from
and against any and all other liabilities, losses, damages, actions, suits, costs, claims and expenses of any kind or nature with respect to the execution, delivery, enforcement, performance and administration of this Agreement (and the commitment
documentation related thereto), the other Loan Documents and any such other documents, including any of the foregoing relating to the use of proceeds of the Revolving Loans or the violation of, noncompliance with or liability under, any
Environmental Law applicable to the operations of any Group Member or any of the Properties and the reasonable and documented or invoiced fees and expenses of one legal counsel for all Indemnitees and, if reasonably necessary, one local counsel for
all Indemnitees taken in each relevant jurisdiction, unless an actual or potential conflict of interest exists, in connection with any actual or prospective claims, actions or proceedings whether based on contract, tort or any other theory, whether
brought by a third party or by the Borrower or any of its Subsidiaries, and regardless of whether any Indemnitee is a party thereto (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”);
provided that the Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities (i) are determined by a final and non-appealable decision of a court of
competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee, (ii) result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for a material breach of such
Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction or
(iii) any proceeding that does not involve an act or omission by the Borrower or any of Borrower’s Affiliates and is brought by an Indemnitee against any other Indemnitee, provided that notwithstanding this clause (iii) the
Administrative Agent shall be indemnified in its capacity as such in all such proceedings. Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert,
and hereby waives and agrees to cause its Subsidiaries to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever


  
 58 









 
kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section 9.5 shall be
payable not later than 10 days after written demand therefor. Statements payable by the Borrower pursuant to this Section 9.5 shall be submitted to the Chief Financial Officer of the Borrower (Telephone No. 785-575-6530) (Telecopy No.
785-575-8061), at the address of the Borrower set forth in Section 9.2, or to such other Person or address as may be hereafter designated by the Borrower in a written notice to the Administrative Agent. The agreements in this
Section 9.5 shall survive the termination of this Agreement. 
 9.6 Successors and Assigns; Participations and
Assignments. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted
assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. 

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees (each, an
“Assignee”) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Commitments and the Revolving Loans at the time owing to it) with the prior written consent (such consent
not to be unreasonably withheld or delayed) of: 
 (A) the Borrower; provided that no consent of the
Borrower shall be required for an assignment to a Lender, an affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other Person; and 

(B) the Administrative Agent and each Issuing Lender; provided that no consent of the Administrative Agent or any
Issuing Lender shall be required for an assignment to an Assignee that is a Lender, an Affiliate of a Lender or an Approved Fund immediately prior to giving effect to such assignment, except in the case of an assignment of a Revolving Commitment to
an Assignee that does not already have a Revolving Commitment. 
 (ii) Assignments shall be subject to the
following additional conditions: 
 (A) except in the case of an assignment to a Lender, an affiliate of a Lender
or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Revolving Commitments or Revolving Loans, the amount of the Revolving Commitments or Revolving 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) shall not be less than $1,000,000 unless each of the Borrower and the Administrative Agent otherwise
consent; provided that (1) no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing and (2) such amounts shall be aggregated in respect of each Lender and its affiliates or Approved
Funds, if any; 
 (B) 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; 
 (C) the Assignee, if it
shall not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire; 

  
 59 









 (D) no such assignment shall be made to (i) the Borrower, KGE or any of
their respective Affiliates or Subsidiaries, (ii) any Defaulting Lender of any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii), or
(iii) a natural person; and 
 (E) 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 Revolving 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 or any Lender hereunder (and interest accrued thereon) and (y) acquire (and fund as appropriate) its full pro
rata share of all Revolving Loans and participations in Letters of Credit and Swingline Loans in accordance with its Revolving 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 paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until
such compliance occurs. 
 For the purposes of this Section 9.6, the term “Approved Fund” means any Person
(other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (1) a Lender, (2) an
Affiliate of a Lender or (3) an entity or an Affiliate of an entity that administers or manages a Lender. 

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) below, from and after the effective
date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning
Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of, and to be bound by its obligations under, Sections 2.13, 2.14,
2.15 and 9.5). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.6 shall be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (c) of this Section. 
 (iv) The
Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices 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 Revolving Commitments of, and principal amount of the Revolving Loans and L/C Obligations owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). In addition, the Administrative Agent shall
maintain on the Register information regarding the designation or revocation of designation of any 

  
 60 









 
Lender as a Defaulting Lender. The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent, each Issuing Lender and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the
Collateral Agent and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Assignee, the
Assignee’s completed administrative questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment
required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless
it has been recorded in the Register as provided in this paragraph. 
 (c) (i) Any Lender may, without the consent of or
notice to the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or
a portion of its Revolving Commitments and the Revolving Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, each Issuing Lender and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights
and obligations under this Agreement. Any agreement 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 may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender
directly affected thereby pursuant to the proviso to the second sentence of Section 9.1 and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be
entitled to the benefits of Sections 2.13, 2.14 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law,
each Participant also shall be entitled to the benefits of Section 9.7(b) as though it were a Lender; provided such Participant shall be subject to Section 9.7(a) as though it were a Lender. 

(ii) 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 interest thereon) of each participant’s interest in the Revolving Loans or other Obligations under this Agreement (a
“Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of its Participant Register to any Person (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) 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. The entries in each Participant Register shall be conclusive absent manifest error, and the Borrower, the Lenders and each Agent shall treat
each Person whose name is recorded in a Participant Register as the owner of such participation for all purposes of this Agreement, notwithstanding notice to the contrary. 

  
 61 









 (iii) A Participant shall not be entitled to receive any greater payment
under Section 2.13 or 2.14 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the
Borrower’s prior written consent. Any Participant that is a Non-U.S. Lender shall not be entitled to the benefits of Section 2.14 unless such Participant complies with Section 2.14(d). 

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure
obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or
assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or Assignee for such Lender as a party hereto. 
 (e) The Borrower, upon receipt of written notice from the relevant Lender, agrees to issue notes to any Lender requiring notes to facilitate transactions of the type described in paragraph (d) above.

 (f) Notwithstanding the foregoing, any Conduit Lender may assign any or all of the Revolving Loans it may have funded
hereunder to its designating Lender without the consent of the Borrower or the Administrative Agent and without regard to the limitations set forth in Section 9.6(b). Each of the Borrower, each Lender and the Administrative Agent hereby
confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar
law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and
hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance. 

9.7 Adjustments; Set-off. 
 (a) Except to the extent that this Agreement expressly provides for payments to be allocated to a particular Lender, if any Lender (a “Benefitted Lender”) shall, at any time after the
Revolving Loans and other amounts payable hereunder shall immediately become due and payable pursuant to Section 7, receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 7(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in
respect of the Obligations owing to such other Lender, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of the Obligations owing to each such other Lender, or shall provide such other
Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any
portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. 

  
 62 









 (b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall
have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated
maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower, as the case may be;
provided that in the event that any Defaulting Lender shall exercise any such right of set-off, (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 2.20 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 Issuing Lenders and the Lenders (including
the Swingline Lender) and (y) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the obligations owing to such Defaulting Lender as to which it exercised such right of set-off.
Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender; provided that the failure to give such notice shall not affect the validity of such setoff and
application. 
 9.8 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any
number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement by facsimile transmission or by email shall be effective
as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. 

9.9 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 9.9, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by
Debtor Relief Laws, as determined in good faith by the Administrative Agent, the Issuing Lenders or the Swingline Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited. 

9.10 Integration. This Agreement and the other Loan Documents represent the entire agreement of the Borrower, the Administrative
Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any Lender relative to the subject matter hereof not expressly set
forth or referred to herein or in the other Loan Documents. 
 9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK (INCLUDING SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, BUT EXCLUDING ALL
OTHER CHOICE OF LAW AND CONFLICTS OF LAW RULES).

 (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law; and

Any provision in any Loan Document (or any document, certificate or statement furnished or made available in connection therewith) referencing, relating to, or purporting to create, any security interest in or other Lien on the Pledged Bonds or

require the payment of interest to any Lender at a rate in excess of the maximum rate permitted by applicable law. If the amount of interest payable for the account of any Lender on any Interest Payment Date would exceed the maximum amount permitted
by applicable law to be charged by such Lender, the amount of interest payable for its account on such Interest Payment Date shall be automatically reduced to such maximum permissible amount. In the event of any such reduction affecting any Lender,
if from time to time thereafter the amount of interest payable for the account of such Lender on any Interest Payment Date would be less than the maximum amount permitted by applicable law to be charged by such Lender, then the amount of interest
payable for its account on such subsequent Interest Payment Date shall be automatically increased to such maximum permissible amount; provided that at no time shall the aggregate amount by which interest paid for the account of any Lender has
been increased pursuant to this sentence exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to the previous sentence.
