 WHEREAS, the Borrower entered into an Amended and Restated Credit Agreement, dated as of May 6, 2005 (as amended, supplemented or otherwise modified from time to time, the “Existing Credit Agreement”), with JPMorgan
Chase Bank, N.A., as administrative agent, and the several banks and other financial institutions or entities parties thereto as lenders; 
 WHEREAS, the parties hereto have agreed to amend and restate the Existing Credit Agreement as provided in this Agreement, which Agreement shall become effective upon the satisfaction of the conditions precedent set forth in Section 4.1
hereof; and 
 WHEREAS, it is the intent of the parties hereto, and the parties hereto agree, that (x) this Agreement shall not
constitute a novation of the obligations and liabilities existing under the Existing Credit Agreement or evidence repayment of any of such obligations or liabilities and (y) this Agreement shall amend and restate in its entirety the Existing
Credit Agreement; 
 NOW, THEREFORE, in consideration of the above premises, the parties hereto hereby agree that on the Closing Date (as
defined below) the Existing Credit Agreement shall be amended and restated in its entirety as follows:

For purposes hereof “Prime Rate” shall mean the rate of interest per annum publicly announced from time to time by JPMorgan Chase Bank, N.A. as its prime rate in effect at its principal office in New
York City (the Prime Rate not being intended to be the lowest rate of interest charged by JPMorgan Chase Bank, N.A. in connection with extensions of credit to debtors). Any change in the ABR due to a change in the Prime Rate or the Federal Funds
Effective Rate shall be effective as of the opening of business on the effective day of such change in the Prime Rate or the Federal Funds Effective Rate, respectively.

 “Affiliate”: as to any Person, any other Person that, directly or indirectly, is in control of, is controlled by, or is under common control with, such Person. For purposes of this definition,
“control” of a Person means the power, directly or indirectly, to direct or cause the direction of the management or policies of such Person, whether through the ability to exercise voting power, by contract or otherwise. 
 “Agents”: the collective reference to the Administrative Agent, the Syndication Agent and the Documentation Agents. 
 “Aggregate Exposure”: with respect to any Lender at any time, an amount equal to the amount of such Lender’s Revolving Commitment
then in effect or, if the Revolving Commitments have been terminated, the amount of such Lender’s Revolving Extensions of Credit then outstanding. 
 “Aggregate Exposure Percentage”: with respect to any Lender at any time, the ratio (expressed as a percentage) of such Lender’s Aggregate Exposure at such time to the Aggregate Exposure of all

non-credit enhanced long-term Indebtedness; provided that if a Debt Rating is issued by each of S&P and Moody’s, then the higher of such Debt Ratings shall apply, unless there is a split in Debt Ratings of more than one level,

effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of
rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of
any such amendment, the Debt Rating shall be determined by reference to the rating most recently in effect prior to such change or cessation.

 SECTION 2. AMOUNT AND TERMS OF

 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 L/C Obligations 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 Eurodollar Loans or ABR Loans, as determined by the Borrower and notified to the Administrative Agent in
accordance with Sections 2.2 and 2.7. 
 (b) At any time prior to the fourth anniversary of the Closing Date, the Borrower and any one or
more Lenders (including any New Lender) may agree that such Lender or Lenders shall make or increase the amount of their Revolving Commitments by executing and delivering to the Administrative Agent an Increased Revolving Commitment Activation
Notice specifying the amount of such increase or new Revolving Commitment and the applicable Increased Revolving Commitment Closing Date (which may be no later than the fourth anniversary of the Closing Date). Notwithstanding the foregoing,
(i) at no time may the Total Revolving Commitments exceed $750,000,000, (ii) Revolving Commitments may not be made or increased after the occurrence and during the continuation of a Default or Event of Default, including after giving
effect to the incremental Revolving Commitments in question, (iii) any increase effected pursuant to this Section 2.1(b) shall be in a minimum amount of at least $25,000,000, (iv) no more than two Increased Revolving Commitment
Closing Dates may be selected by the Borrower during the term of this Agreement and (v) prior to the Collateral Release Date, no increase of Revolving Commitments pursuant to Section 2.1(b) shall be effective until Section 3(c) of the
KGE Collateral Agreement is satisfied. No Lender shall have any obligation to participate in any increase described in this Section 2.1(b) unless it agrees to do so in its sole discretion. 
 (c) Any additional bank, financial institution or other entity (each, a “New Lender”) that, in the case of an institution that is not an
Approved Fund or an affiliate of a then-existing Lender, with the consent of the Administrative Agent and each Issuing Lender (which consent, in each case, shall not be unreasonably withheld), elects to become a “Lender” under this
Agreement in connection with an 
  

 15 








 increase described in Section 2.1(b) shall execute a New Lender Supplement (each, a “New Lender
Supplement”), substantially in the form of Exhibit E-1, whereupon such bank, financial institution or other entity shall become a Lender for all purposes and to the same extent as if originally a party hereto and shall be bound by and
entitled to the benefits of this Agreement. 
 (d) On each Increased Revolving Commitment Closing Date on which there are Revolving Loans
outstanding, each Lender (including any New Lender) that has made or increased its Revolving Commitment shall make a Revolving Loan, the proceeds of which will be used to prepay the Revolving Loans of other Lenders, so that, after giving effect
thereto, the resulting Revolving Loans outstanding are allocated among the Lenders in accordance with Section 2.12(a) based on the respective Revolving Percentages of the Lenders after giving effect to the increase of Revolving Commitments
pursuant to Section 2.1(b) on such Increased Revolving Commitment Closing Date. Any remaining proceeds shall be used in accordance with Section 3.16. 
 (e) The Borrower shall repay to each Lender its outstanding Revolving Loans on the Revolving Termination Date, the Extended Revolving Termination Date or the Second Extended Revolving Termination Date, as applicable,
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 any anniversary of the Closing Date (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 will be extended for an additional year from the Revolving Termination Date (the “Extended Revolving Termination
Date”) or the Extended Revolving Termination Date (the “Second Extended Revolving Termination Date”), as applicable; 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 representations and warranties set
forth in Section 3 hereof shall be true and correct in all material respects 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 shall be true and correct in all material respects 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 twice pursuant to this Section 2.1(e). 
 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 
  

 16 








 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 Eurodollar Loans, or (b) on the requested Borrowing Date, in the case of ABR Loans) (provided that any such
notice of a borrowing of ABR Loans to finance payments required by Section 2.3(i) 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 Eurodollar Loans, the respective lengths of the initial Interest Period therefor. Any Revolving Loans made on the
Closing Date may be ABR Loans or Eurodollar Loans. 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). 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 pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the Funding Office prior to 12:00 Noon, 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(f), agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower on any Business Day during the Revolving Commitment Period 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 would exceed
the L/C Commitment or (ii) the aggregate amount of the Available Revolving Commitments would be less than zero. 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 (which shall in no event extend beyond the date referred to in clause (y) above) and; provided further that at any time the Revolving Commitments have been extended pursuant to Section 2.1(e), 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. Letters of Credit issued under the Existing Credit Agreement and outstanding on the Closing Date shall continue to
constitute Letters of Credit hereunder. 
 (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 
  

 17 








 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) The Borrower will pay a fee on all outstanding Letters of Credit at a per annum rate equal to the Applicable
Margin then in effect with respect to Eurodollar Loans, shared ratably among the Lenders and payable quarterly in arrears on each Fee Payment Date after the issuance date. In addition, the Borrower shall pay to each applicable Issuing Lender for its
own account a fronting fee (not to exceed 0.125% per annum) 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.

 (e) 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. 
 (f) 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, and such amount equal to such L/C
Participant’s Revolving Percentage of the amount of such draft shall be deemed to be a Revolving Loan for all purposes hereunder. Each L/C Participant’s obligation to pay such amount 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. 
 (g) If any amount required to be paid by any L/C Participant to any Issuing Lender pursuant to Section 2.3(f) 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(f) 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 
  

 18 








 interest thereon calculated from such due date at the rate per annum applicable to ABR 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. 
 (h) 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 pro rata share of such payment in accordance with Section 2.3(f), 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 pro rata share thereof; provided, however, that in the event that any such payment received by such Issuing Lender shall be required to be returned by the Issuing Lender, such
L/C Participant shall return to such Issuing Lender the portion thereof previously distributed by such Issuing Lender to it. 
 (i) 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(f). 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). 
 (j) 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(i) 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 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. 
 (k) 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. 
  

 19 








 (l) 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. 
 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 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.

 (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 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. Notwithstanding any such reduction, the amount of the Revolving Commitments may be increased pursuant to Section 2.1(b). 
 2.6. Optional Prepayments The Borrower may at any time and from time to time prepay the Revolving Loans, in whole or in part, without premium or
penalty, upon irrevocable notice delivered to the Administrative Agent no later than 11:00 A.M., New York City time, three Business Days prior thereto in the case of Eurodollar Loans, and no later than 11:00 A.M., New York City time, on the Business
Day thereof in the case of ABR Loans, which notice shall specify the date and amount of prepayment and whether the prepayment is of Eurodollar Loans or ABR Loans; provided, that if a Eurodollar 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 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. 
 2.7. Conversion and Continuation Options (a) The Borrower may elect from time to
time to convert Eurodollar Loans to ABR 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 Eurodollar 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 ABR Loans to Eurodollar 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 ABR Loan may be
converted into a Eurodollar 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 conversions. Upon receipt of any such
notice the Administrative Agent shall promptly notify each relevant Lender thereof. 
 (b) Any Eurodollar 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 

 

 20 








 in Section 1.1, of the length of the next Interest Period to be applicable to such Revolving Loans, provided
that no Eurodollar Loan may be continued as such when any Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations, and
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 ABR 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 Eurodollar Tranches Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions and continuations
of Eurodollar 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 Eurodollar Loans comprising each
Eurodollar 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 Eurodollar Tranches shall be outstanding at any one time. 
 2.9. Interest Rates and Payment Dates (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto
at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin. 
 (b) Each ABR Loan shall bear interest
at a rate per annum equal to the ABR plus the Applicable Margin. 
 (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 ABR 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 (i) with respect to the Commitment Fee and (ii) with respect to ABR Loans the rate of interest on which is calculated on the basis of the Prime Rate, such Commitment Fee or such interest thereon 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 Eurodollar Rate. Any change in
the interest rate on a Revolving Loan resulting from a change in the ABR or the Eurocurrency 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). 
  

 21 








 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 Eurodollar Rate for such Interest Period, or 
 (b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar 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 Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Revolving Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall
be continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then-current Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar
Loans shall be made or continued as such, nor shall the Borrower have the right to convert Revolving Loans to Eurodollar Loans. 
 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 Eurodollar 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 Eurodollar 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, 
  

 22 








 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 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 ABR 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: 
 (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 Eurodollar 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 Eurodollar 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 Eurodollar 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. 
  

 23 








 (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 regarding capital adequacy (whether or not having the force of law) from
any Governmental Authority made subsequent to the date hereof 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; and 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, excluding 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). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“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, provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are 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 from the Borrower with respect to such Non-Excluded Taxes
pursuant to this paragraph. 
 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance
with applicable law. 
  

 24 








 (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).
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. 
 (f) 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 Eurodollar 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 Eurodollar 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 Eurodollar Loans on a day that is not the last day of an Interest 
  

 25 








 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 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, and 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 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 2.14(a) or (b) defaults in its obligation to make Revolving Loans hereunder, with a replacement financial
institution; provided that (i) such 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 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 Eurodollar 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 2.14(a), as the case may be, and (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. 
 SECTION 3. REPRESENTATIONS AND
WARRANTIES 
 To induce the Administrative Agent and the Lenders to enter into this Agreement and to make the Revolving Loans and issue or
participate in the Letters of Credit, 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, 2005, audited by and accompanied 
  

 26 








 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, 2005 to and including the date
hereof, 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, 2005, 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 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. 
  

 27 








 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 any Significant Subsidiary 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 any Significant Subsidiary 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.

 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. 
  

 28 








 3.13. ERISA. Neither a Reportable Event nor an “accumulated funding deficiency” (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 shall be used for general corporate purposes, including, but not limited to, repayment
of any Indebtedness. 
 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 
  

 29 








 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 (a) do not 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 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 and the financing statements and other filings specified on Schedule 3.19(a)

  

 30 








 in appropriate form are filed in the offices specified on Schedule 3.19(a), 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).

 3.20. Solvency Each Loan Party is, and after giving effect to the incurrence of all Indebtedness and obligations being incurred in
connection herewith will be, Solvent.

 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 
  

 43 








 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 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. 
 8.5. Notice of Default The Administrative Agent shall not be 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 
  

 44 








 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 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 
  

 45 








 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 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) reduce any percentage specified in the definition of Required Lenders or Supermajority Lenders, 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; or (vii) amend, modify or waive any provision of Section 2.3
without the written consent of each Issuing 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 
  

 46 








 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.

 9.3. No Waiver; Cumulative Remedies No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any
right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise

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 fees and disbursements of counsel to the Administrative Agent 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

any such other documents, including the fees and disbursements of counsel (including the allocated fees and expenses of in-house 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, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever 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 fees and expenses of legal counsel in
connection with claims, actions 
  

 48 








 or proceedings by any third party against any Loan Party or any Indemnitee under any Loan Document (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 are
found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee. 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 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. 785-575-1987) (Telecopy
No. 785-575-1936), 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 repayment of the Revolving Loans and all other amounts payable hereunder. 
 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; 
  

 49 








 (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; and 
 (C) the Assignee, if it shall
not be a Lender, shall deliver to the Administrative Agent an administrative questionnaire. 
 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 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”). The
entries in the Register shall be conclusive, 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. 
 (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 
  

 50 








 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) 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 
  

 51 








 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. 
 (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. 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 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. 
 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. 
 9.12.

 (a) submits for itself and
its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the
courts of the State of New York, the courts of the United States for the Southern District of New York, and appellate courts from any thereof;

mail (or any substantially similar form of mail), postage prepaid, to the Borrower at its address set forth in Section 9.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto; 
 (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the
right to sue in any other jurisdiction; and 
 (e) waives, to the maximum extent not prohibited by law, any right it may have
to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages. 
 9.13. Acknowledgements The Borrower hereby acknowledges that: 
 (a) it has been advised by counsel in the
negotiation, execution and delivery of this Agreement and the other Loan Documents; 
 (b) neither the Administrative Agent
nor any Lender has any fiduciary relationship with or duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and the
Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and 
 (c) no joint
venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Borrower and the Lenders. 
 9.14. Confidentiality Each of the Administrative Agent and each Lender agrees to keep confidential all non-public information provided to it by
any Loan Party pursuant to this Agreement that is designated by such Loan Party as confidential; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the Administrative
Agent, any other Lender or any affiliate thereof or any Approved Fund, (b) subject to an agreement to comply with the provisions of this Section, to any actual or prospective Transferee or any direct or indirect counterparty to any Swap

law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies Borrower, which information includes the name, address and tax identification number of Borrower and other information
regarding Borrower that will allow such Lender or the Administrative Agent, as applicable, to identify Borrower in accordance with the Act. This notice is given in accordance with the requirements of the Act and is effective as to the Lenders and
