 THE CREDITS 
  
 Section 2.01. Commitments to Lend. (a) Revolving Credit Loans. During its Revolving Credit Period, each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make loans to each Borrower
pursuant to this subsection from time to time; provided that, immediately after each such loan is made, (i) the aggregate outstanding principal amount of such Bank’s Loans to all Borrowers plus the aggregate amount of such
Bank’s Letter of Credit Liabilities shall not exceed its Commitment and (ii) the aggregate 

  

 6 








 
outstanding principal amount of Loans to any Borrower plus the aggregate amount of Letter of Credit Liabilities for the account of such Borrower shall not exceed the
Maximum Availability of such Borrower. Each Borrowing under this subsection shall be in an aggregate principal amount of $10,000,000 or any larger multiple of $1,000,000 (except that any such Borrowing may be in the aggregate amount available in
accordance with Section 3.02(b)) and shall be made from the several Banks ratably in proportion to their respective Commitments in effect on the date of Borrowing; provided that, if the Interest Period selected by the Borrower for a
Borrowing would otherwise end after the Commitment Termination Dates of some but not all Banks, the Borrower may in its Notice of Borrowing elect not to borrow from those Banks whose Commitment Termination Dates fall prior to the end of such
Interest Period. Within the foregoing limits, the Borrowers may borrow under this subsection (a), or to the extent permitted by Section 2.11, prepay Loans and reborrow at any time during the Revolving Credit Periods under this subsection (a).

 (b) Term Loans. Each Bank severally agrees, on the terms and conditions set forth in this Agreement, to make a loan to each
Borrower on its Commitment Termination Date; provided that, immediately after each such loan is made, (i) the aggregate outstanding principal amount of such Bank’s Loans to all Borrowers plus the aggregate amount of such Bank’s
Letter of Credit Liabilities shall not exceed its Commitment and (ii) the aggregate outstanding principal amount of such Bank’s Loans to any Borrower plus the aggregate amount of such Bank’s Letter of Credit Liabilities for the
account of such Borrower shall not exceed such Bank’s Percentage of the Maximum Availability of such Borrower; and provided further that no Bank shall be obligated to make a loan pursuant to this subsection if any Commitment shall have
been extended pursuant to Section 2.01(c) to a date later than the Commitment Termination Date of such Bank. Each Borrowing under this Section 2.01(b) shall be made from the several Banks having the same Commitment Termination Date ratably
in proportion to their respective Commitments. 
 (c) Extension of Commitments. Cinergy may, upon notice to the Administrative
Agent not less than 60 days but no more than 90 days prior to any anniversary of the Effective Date, propose to extend the Commitment Termination Dates for an additional one-year period measured from the Commitment Termination Dates then in effect.
The Administrative Agent shall promptly notify the Banks of receipt of such request. Each Bank shall endeavor to respond to such request, whether affirmatively or negatively (such determination in the sole discretion of such Bank), by notice to
Cinergy and the Administrative Agent within 30 days. Subject to the execution by the Borrowers, the Administrative Agent and such Banks of a duly completed Extension Agreement in substantially the form of Exhibit E, the Commitment Termination Date
applicable to the Commitment of each Bank so affirmatively notifying Cinergy and the Administrative Agent shall be extended for the period specified above; provided that no Commitment Termination Date of any Bank shall be extended unless
Banks having Commitments in an aggregate amount equal to at least 51% in aggregate amount of the Commitments in effect at the time any such extension is requested shall have elected so to extend their Commitments. Any Bank which does not give such
notice to Cinergy and the Administrative Agent shall be deemed to have elected not to extend as requested, and the Commitment of each non-extending Bank shall terminate on its Commitment Termination Date determined without giving effect to such
requested extension. Cinergy may, in accordance with Section 8.06, designate another bank or other financial institution (which may be, but need not be, an extending Bank) to replace a non-extending Bank. 
 Section 2.02. Notice of Borrowings. The Borrower shall give the Administrative Agent notice (a “Notice of Borrowing”) not later than
11:00 A.M. (New York City time) on (x) the date of each Base Rate Borrowing and (y) the third Euro-Dollar Business Day before each Euro-Dollar Borrowing, specifying: 
 (a) the date of such Borrowing, which shall be a Domestic Business Day in the case of a Domestic Borrowing or a Euro-Dollar Business Day in the case
of a Euro-Dollar Borrowing; 
 (b) the aggregate amount of such Borrowing; 
 (c) whether the Loans comprising such Borrowing are to bear interest initially at the Base Rate or a Euro-Dollar Rate; and 
 (d) in the case of a Euro-Dollar Borrowing, the duration of the initial Interest Period applicable thereto, subject to the provisions of the
definition of Interest Period. 
 Section 2.03. Notice to Banks; Funding of Loans. (a) Upon receipt of a Notice of Borrowing,
the Administrative Agent shall promptly notify each Bank of the contents thereof and of such Bank’s share (if any) of such Borrowing and such Notice of Borrowing shall not thereafter be revocable by the Borrower. 
 (b) Not later than 1:00 P.M. (New York City time) on the date of each Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address specified in or pursuant to Section 9.01. Unless the
Administrative Agent determines that any applicable condition specified in Article 3 has not been satisfied, the Administrative Agent will make the funds so received from the Banks available to the Borrower at the Administrative Agent’s
aforesaid address. 
 (c) Unless the Administrative Agent shall have received notice from a Bank prior to the date of any Borrowing that
such Bank will not make available to the Administrative Agent such Bank’s share of such Borrowing, the Administrative Agent may assume that such Bank has made such share available to the Administrative Agent on the date of such Borrowing in
accordance with subsection (b) of 

  

 7 








 
this Section 2.03 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and
to the extent that such Bank shall not have so made such share available to the Administrative Agent, such Bank and, if such Bank shall not have made such payment within two Domestic Business Days of demand therefor, the Borrower severally agree to
repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative
Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.06 and (ii) in the case of such Bank, the Federal Funds Rate. If
such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Loan included in such Borrowing for purposes of this Agreement. 
 (d) The failure of any Bank to make the Loan to be made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any,
hereunder to make a Loan on the date of such Borrowing, but no Bank shall be responsible for the failure of any other Bank to make a Loan to be made by such other Bank. 
 Section 2.04. Registry; Notes. (a) The Administrative Agent shall maintain a register (the “Register”) on which it will record the Commitment of each Bank, each Loan made by such Bank
and each repayment of any Loan made by such Bank. Any such recordation by the Administrative Agent on the Register shall be conclusive, absent manifest error. Failure to make any such recordation, or any error in such recordation, shall not affect
the Borrowers’ obligations hereunder. 
 (b) Each Borrower hereby agrees that, promptly upon the request of any Bank at any time,
such Borrower shall deliver to such Bank a duly executed Note, in substantially the form of Exhibit A hereto, payable to the order of such Bank and representing the obligation of such Borrower to pay the unpaid principal amount of the Loans made to
such Borrower by such Bank, with interest as provided herein on the unpaid principal amount from time to time outstanding. 
 (c) Each
Bank shall record the date, amount and maturity of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and each Bank receiving a Note pursuant to this Section, if such Bank so elects
in connection with any transfer or enforcement of its Note, may endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the
failure of such Bank to make any such recordation or endorsement shall not affect the obligations of any Borrower hereunder or under the Notes. Such Bank is hereby irrevocably authorized by each Borrower so to endorse its Note and to attach to and
make a part of its Note a continuation of any such schedule as and when required. 
 Section 2.05. Maturity of Loans; Effect of Cash
Collateralization of Letters of Credit. (a) Each Revolving Credit Loan made by any Bank shall mature, and the principal amount thereof shall be due and payable together with accrued interest thereon, on the Commitment Termination
Date of such Bank. 
 (b) The Term Loan of each Bank shall mature, and the principal amount thereof shall be due and payable, together
with accrued interest thereon, on the Final Maturity Date. 
 (c) If any provision of any debt instrument or other agreement or
instrument binding upon any Borrower, including without limitation this Agreement, would be contravened by any deposit required hereunder to cash collateralize any Letter of Credit Liabilities of such Borrower, such Borrower shall either
(x) obtain a waiver of such provision, (y) prepay the debt incurred under such debt instrument and terminate such debt instrument or (z) make other arrangements satisfactory to the Required Banks; it being understood and agreed that
the risk of any such contravention shall be borne solely by the Borrowers and not by the Banks and shall in no event constitute a defense available to any Borrower for nonperformance of its obligations hereunder. 
 Section 2.06. Interest Rates. (a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the
date such Loan is made until it becomes due, at a rate per annum equal to the Base Rate for such day. Such interest shall be payable quarterly in arrears on each Quarterly Payment Date, at maturity and on the date of termination of the Commitments
in their entirety. Any overdue principal of or overdue interest on any Base Rate Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the sum of 1% plus the Base Rate for such day. 
 (b) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for each day during each Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such day plus the London Interbank Offered Rate applicable to such Interest Period. Such interest shall be payable for each Interest Period on the last day thereof and, if
such Interest Period is longer than three months, at intervals of three months after the first day thereof. 
 The “London
Interbank Offered Rate” applicable to any Interest Period means the rate appearing on Page 3750 of the Telerate Service Company (or on any successor or substitute page of such service, or any successor to or substitute for such service,
providing rate quotations comparable to those currently provided on such page of the Telerate Service, as may be nominated by the British Bankers’ Association for purposes of providing quotations of interest rates applicable to dollar deposits
in the London interbank market) as of 11:00 A.M. (London time) two Euro-Dollar Business Days prior to the commencement of such 

  

 8 








 
Interest Period, as the rate for dollar deposits with a maturity comparable to such Interest Period. In the event that such rate is not so available at such time for
any reason, then the “London Interbank Offered Rate” for such Interest Period shall be the average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the respective rates per annum at which deposits in dollars are
offered to each of the Euro-Dollar Reference Banks in the London interbank market at approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the first day of such Interest Period in an amount approximately equal to the principal
amount of the Loan of such Euro-Dollar Reference Bank to which such Interest Period is to apply and for a period of time comparable to such Interest Period. If any Euro-Dollar Reference Bank does not furnish a timely quotation, the Administrative
Agent shall determine the relevant interest rate on the basis of the quotation furnished by the remaining Euro-Dollar Reference Bank or, if none of such quotations is available on a timely basis, the provisions of Section 8.01 shall apply.

 (c) Any overdue principal of or overdue interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from
and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of 1% plus the higher of (i) the sum of the Euro-Dollar Margin for such day plus the London Interbank Offered Rate
applicable to such Loan at the date such payment was due and (ii) the Base Rate for such day. 
 (d) The Administrative Agent shall
determine each interest rate applicable to the Loans hereunder. The Administrative Agent shall give prompt notice to the Borrower and the participating Banks by telecopy, telex or cable of each rate of interest so determined, and its determination
thereof shall be conclusive in the absence of manifest error unless the Borrower raises an objection thereto within five Domestic Business Days after receipt of such notice. 
 Section 2.07. Fees. (a) Facility Fees. Cinergy shall pay to the Administrative Agent, for the account of the Banks ratably in proportion to
their Credit Exposures, a facility fee calculated for each day at the Facility Fee Rate for such day (determined in accordance with the Pricing Schedule) on the aggregate amount of the Credit Exposures on such day; provided that if at any
time Cinergy shall fail to pay such facility fee within five days of the date when such facility fee is due, each of CG&E, PSI Energy and ULH&P severally, but not jointly, agrees to pay upon demand to the Administrative Agent for the account
of each Bank the amount of such unpaid facility fee multiplied by the percentage which the Maximum Availability applicable to such Borrower represents of the aggregate Commitments (it being understood that Cinergy shall remain liable for any unpaid
amounts). Such facility fee shall accrue for each day from and including the Effective Date but excluding the day on which the Credit Exposures are reduced to zero. 
 (b) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent (i) for the account of the Banks ratably a letter of
credit fee accruing daily on the aggregate amount then available for drawing under all outstanding Letters of Credit at a rate per annum equal to the then applicable Euro-Dollar Margin and (ii) for the account of each Issuing Bank a letter of
credit fronting fee accruing daily on the aggregate amount then available for drawing under all Letters of Credit issued by such Issuing Bank at a rate per annum of 0.125% (or such other rate as may be mutually agreed from time to time by the
Borrower and such Issuing Bank). 
 (c) Payments. Accrued fees under this Section for the account of any Bank shall be payable
quarterly in arrears on each Quarterly Payment Date and upon such Bank’s Commitment Termination Date and Final Maturity Date (and, if later, the date the Credit Exposure of such Bank is reduced to zero). 
 Section 2.08. Optional Termination or Reduction of Commitments and Maximum Availabilities. (a) Cinergy may, upon at least three Domestic Business
Days’ notice to the Administrative Agent, (i) terminate the Commitments at any time, if no Loans or Letter of Credit Liabilities are outstanding at such time, or (ii) ratably reduce from time to time by an aggregate amount of
$10,000,000 or any larger multiple of $1,000,000 the aggregate amount of the Commitments in excess of the aggregate Utilization. 
 (b)
Each Borrower, other than Cinergy, may, upon at least three Domestic Business Days’ notice to the Administrative Agent, reduce its Maximum Availability (i) to zero, if no Loans to it or Letter of Credit Liabilities for its account are
outstanding or (ii) by an amount of $10,000,000 or any larger multiple of $1,000,000 so long as, after giving effect to such reduction, its Maximum Availability is not less than the sum of the aggregate principal amount of Loans outstanding to
it and the aggregate Letter of Credit Liabilities outstanding for its account. Upon any reduction in the Maximum Availability of a Borrower to zero pursuant to this Section 2.08(b), such Borrower shall cease to be a Borrower hereunder.

 Section 2.09. Method of Electing Interest Rates. (a) The Loans included in each Borrowing shall bear interest initially at
the type of rate specified by the Borrower in the applicable Notice of Borrowing. Thereafter, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Group of Loans (subject in each case to the
provisions of Article 8 and the last sentence of this subsection (a)), as follows: 
 (i) if such Loans are Base Rate Loans, the
Borrower may elect to convert such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day; and 
 (ii) if such Loans are
Euro-Dollar Loans, the Borrower may elect to convert such Loans to Base Rate Loans or elect to continue such Loans as Euro-Dollar Loans for an additional Interest Period, subject to Section 2.13 in the case of any such conversion or
continuation effective on any day other than the last day of the then current Interest Period applicable to such Loans. 
  

 9 








 Each such election shall be made by delivering a notice (a “Notice of Interest Rate Election”) to the
Administrative Agent not later than 11:00 A.M. (New York City time) on the third Euro-Dollar Business Day before the conversion or continuation selected in such notice is to be effective. A Notice of Interest Rate Election may, if it so specifies,
apply to only a portion of the aggregate principal amount of the relevant Group of Loans; provided that (i) such portion is allocated ratably among the Loans comprising such Group and (ii) the portion to which such notice applies,
and the remaining portion to which it does not apply, are each $10,000,000 or any larger multiple of $1,000,000. 
 (b) Each Notice of
Interest Rate Election shall specify: 
 (i) the Group of Loans (or portion thereof) to which such notice applies; 
 (ii) the date on which the conversion or continuation selected in such notice is to be effective, which shall comply with the applicable clause of
subsection 2.09(a) above; 
 (iii) if the Loans comprising such Group are to be converted, the new type of Loans and, if the Loans being
converted are to be Euro-Dollar Loans, the duration of the next succeeding Interest Period applicable thereto; and 
 (iv) if such Loans
are to be continued as Euro-Dollar Loans for an additional Interest Period, the duration of such additional Interest Period. 
 Each Interest Period specified in a
Notice of Interest Rate Election shall comply with the provisions of the definition of the term “Interest Period”. 
 (c) Promptly after receiving a Notice of Interest Rate Election from the Borrower pursuant to subsection 2.09(a) above, the Administrative Agent shall notify each Bank of the contents thereof and such notice shall not thereafter be
revocable by the Borrower. If no Notice of Interest Rate Election is timely received prior to the end of an Interest Period for any Group of Loans, the Borrower shall be deemed to have elected that such Group of Loans be converted to Base Rate Loans
as of the last day of such Interest Period. 
 (d) An election by the Borrower to change or continue the rate of interest applicable to
any Group of Loans pursuant to this Section shall not constitute a “Borrowing” subject to the provisions of Section 3.02. 
 Section 2.10. Mandatory Termination of Commitments. The Commitment of each Bank shall terminate on such Bank’s Commitment Termination Date. 
 Section 2.11. Optional Prepayments. (a) The Borrower may (i) upon notice to the Administrative Agent not later than 11:00 A.M. (New York City time) on any Domestic Business Day prepay on such
Domestic Business Day any Group of Base Rate Loans and (ii) upon at least three Euro-Dollar Business Days’ notice to the Administrative Agent not later than 11:00 A.M. (New York City time) prepay any Group of Euro-Dollar Loans, in each
case in whole at any time, or from time to time in part in amounts aggregating $5,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to the date of prepayment and
together with any additional amounts payable pursuant to Section 2.13. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Banks included in such Group or Borrowing. 
 (b) Upon receipt of a notice of prepayment pursuant to this Section, the Administrative Agent shall promptly notify each Bank of the contents
thereof and of such Bank’s share (if any) of such prepayment and such notice shall not thereafter be revocable by the Borrower. 
 Section 2.12. General Provisions as to Payments. (a) The Borrower shall make each payment of principal of, and interest on, the Loans and of fees hereunder, not later than 1:00 P.M. (New York City time) on the date
when due, in Federal or other funds immediately available in New York City, to the Administrative Agent at its address referred to in Section 9.01 and without reduction by reason of any set-off, counterclaim or deduction of any kind. The
Administrative Agent will promptly distribute to each Bank in like funds its ratable share of each such payment received by the Administrative Agent for the account of the Banks. Whenever any payment of principal of, or interest on, the Base Rate
Loans or Letter of Credit Liabilities or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or
interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another
calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such
extended time. 
 (b) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any
payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent
may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent,
at the Federal Funds Rate. 
  

 10 








 Section 2.13. Funding Losses. If the Borrower makes any payment of principal with respect to any
Euro-Dollar Loan or any Euro-Dollar Loan is converted to a Base Rate Loan or continued as a Euro-Dollar Loan for a new Interest Period (pursuant to Article 2, 6 or 8 or otherwise) on any day other than the last day of an Interest Period applicable
thereto, or if the Borrower fails to borrow, prepay, convert or continue any Euro-Dollar Loans after notice has been given to any Bank in accordance with Section 2.03(a), 2.09(c) or 2.11(b), the Borrower shall reimburse each Bank within 15 days
after demand for any resulting loss or expense incurred by it (or by an existing or prospective Participant in the related Loan), including (without limitation) any loss incurred in obtaining, liquidating or employing deposits from third parties,
but excluding loss of margin for the period after any such payment or conversion or failure to borrow, prepay, convert or continue; provided that such Bank shall have delivered to the Borrower a certificate setting forth in reasonable detail
the calculation of the amount of such loss or expense, which certificate shall be conclusive in the absence of manifest error. 
 Section 2.14.
Computation of Interest and Fees. Interest based on the Base Rate and facility fees hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first
day but excluding the last day). All other interest and Letter of Credit fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day). 
  
 Section 2.15. Letters of Credit. 
 (a) Subject to the terms and conditions hereof, each Issuing Bank agrees to issue Letters of Credit hereunder from time to time before its
Commitment Termination Date upon the request and for the account of any Borrower; provided that, immediately after each Letter of Credit is issued, (i) the Utilization shall not exceed the aggregate amount of the Commitments,
(ii) the aggregate outstanding principal amount of Loans to any Borrower plus the aggregate amount of Letter of Credit Liabilities for the account of such Borrower shall not exceed the Maximum Availability of such Borrower and (iii) the
aggregate amount of the Letter of Credit Liabilities shall not exceed $1,000,000,000. Upon the date of issuance by the Issuing Bank of a Letter of Credit, the Issuing Bank shall be deemed, without further action by any party hereto, to have sold to
each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuing Bank, a participation in such Letter of Credit and the related Letter of Credit Liabilities in the proportion its Commitment
bears to the aggregate Commitments; provided that (i) if the scheduled Commitment Termination Date of a Bank falls prior to the expiry date of a Letter of Credit then outstanding and the Commitments of the other Banks are extended on
such date in accordance with Section 2.01(c), such Bank’s participation in such Letter of Credit shall terminate on its Commitment Termination Date, and the participations of the other Banks therein shall be redetermined pro rata in
proportion to their Commitments after giving effect to the termination of the Commitment of such former Bank; and (ii) in the event that the Commitments of the other Banks are not extended in accordance with Section 2.01(c), then such
Bank’s participation in all Letters of Credit shall remain at the level existing prior to the proposed extension, regardless of whether the expiry of any such Letters of Credit extends beyond such Bank’s Commitment Termination Date. If and
to the extent necessary to permit redetermination of the participations in Letters of Credit pursuant to clause (i) of the foregoing proviso within the limits of the Commitments which are not terminated, the Borrowers shall prepay on such date
all or a portion of the outstanding Loans and/or secure cancellation of outstanding Letters of Credit, and such redetermination and termination of participations in outstanding Letters of Credit shall be conditioned upon their having done so.

 (b) The Borrower shall give the Issuing Bank notice at least three Domestic Business Days prior to the requested issuance of a Letter
of Credit, or in the case of a Letter of Credit substantially in the form of Exhibit G, at least one Business Day prior to the requested issuance of such Letter of Credit, specifying the date such Letter of Credit is to be issued and describing the
terms of such Letter of Credit (such notice, including any such notice given in connection with the extension of a Letter of Credit, a “Notice of Issuance”), substantially in the form of Exhibit F, appropriately completed. Upon
receipt of a Notice of Issuance, the Issuing Bank shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Bank of the contents thereof and of the amount of such Bank’s participation in such Letter
of Credit. The issuance by the Issuing Bank of each Letter of Credit shall, in addition to the conditions precedent set forth in Article 3, be subject to the conditions precedent that such Letter of Credit shall be denominated in U.S. dollars and
shall be in such form and contain such terms as shall be reasonably satisfactory to the Issuing Bank. Unless otherwise notified by the Administrative Agent, the Issuing Bank may, but shall not be required to, conclusively presume that all conditions
precedent set forth in Article 3 have been satisfied. The Borrower shall also pay to each Issuing Bank for its own account issuance, drawing, amendment and extension charges in the amounts and at the times as agreed between the Borrower and such
Issuing Bank. Except for non-substantive amendments to any Letter of Credit for the purpose of correcting errors or ambiguities or to allow for administrative convenience (which amendments each Issuing Bank may make in its discretion with the
consent of the Borrower), the amendment, extension or renewal of any Letter of Credit shall be deemed to be an issuance of such Letter of Credit. If any Letter of Credit contains a provision pursuant to which it is deemed to be automatically
renewed unless notice of termination is given by the Issuing Bank of such Letter of Credit, the Issuing Bank shall timely give notice of termination if (i) as of close of business on the seventeenth day prior to the last day upon which the
Issuing Bank’s notice of termination may be given to the beneficiaries of such Letter of Credit, the Issuing Bank has received a notice of termination from the Borrower or a notice from 

  

 11 








 
the Administrative Agent that the conditions to issuance of such Letter of Credit have not been satisfied or (ii) the renewed Letter of Credit would have a term
not permitted by subsection (c) below. 
 (c) No Letter of Credit shall have a term extending beyond the first anniversary of the
Commitment Termination Date of the applicable Issuing Bank. 
 (d) Upon receipt from the beneficiary of any applicable Letter of Credit
of any notice of a drawing under such Letter of Credit, the Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Bank as to the amount to be paid as a result of such demand
or drawing and the payment date. The Borrower shall be irrevocably and unconditionally obligated forthwith to reimburse the Issuing Bank for any amounts paid by the Issuing Bank upon any drawing under any Letter of Credit without presentment,
demand, protest or other formalities of any kind. All such amounts paid by the Issuing Bank and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Base Rate for such day
plus, if such amount remains unpaid for more than two Domestic Business Days, 1%. In addition, each Bank will pay to the Administrative Agent, for the account of the applicable Issuing Bank, immediately upon such Issuing Bank’s demand at any
time during the period commencing after such drawing until reimbursement therefor in full by the Borrower, an amount equal to such Bank’s ratable share of such drawing (in proportion to its participation therein), together with interest on such
amount for each day from the date of the Issuing Bank’s demand for such payment (or, if such demand is made after 12:00 Noon (New York City time) on such date, from the next succeeding Domestic Business Day) to the date of payment by such Bank
of such amount at a rate of interest per annum equal to the Federal Funds Rate and, if such amount remains unpaid for more than five Domestic Business Days after the Issuing Bank’s demand for such payment, at a rate of interest per annum equal
to the Base Rate plus 1%. The Issuing Bank will pay to each Bank ratably all amounts received from the Borrower for application in payment of its reimbursement obligations in respect of any Letter of Credit, but only to the extent such Bank has made
payment to the Issuing Bank in respect of such Letter of Credit pursuant hereto. 
 (e) The obligations of the Borrower and each Bank
under subsection 2.15(d) above shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including without limitation the following
circumstances: 
 (i) the use which may be made of the Letter of Credit by, or any acts or omission of, a beneficiary of a Letter of
Credit (or any Person for whom the beneficiary may be acting); 
 (ii) the existence of any claim, set-off, defense or other rights that
the Borrower may have at any time against a beneficiary of a Letter of Credit (or any Person for whom the beneficiary may be acting), the Banks (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter
of Credit or any document related hereto or thereto or any unrelated transaction; 
 (iii) any statement or any other document presented
under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; 
 (iv) payment under a Letter of Credit to the beneficiary of such Letter of Credit against presentation to the Issuing Bank of a draft or certificate
that does not comply with the terms of the Letter of Credit; provided that the determination by the Issuing Bank to make such payment shall not have been the result of its willful misconduct or gross negligence; or 
 (v) any other act or omission to act or delay of any kind by any Bank (including the Issuing Bank), the Administrative Agent or any other Person or
any other event or circumstance whatsoever that might, but for the provisions of this subsection (v), constitute a legal or equitable discharge of the Borrower’s or the Bank’s obligations hereunder. 
 (f) The Borrower hereby indemnifies and holds harmless each Bank (including the Issuing Bank) and the Administrative Agent from and against any and
all claims, damages, losses, liabilities, costs or expenses which such Bank or the Administrative Agent may incur (including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the Issuing Bank may incur by reason
of or in connection with (i) the failure of any other Bank to fulfill or comply with its obligations to such Issuing Bank hereunder (but nothing herein contained shall affect any rights the Borrower may have against such defaulting Bank) or
(ii) any litigation arising with respect to this Agreement (whether or not the Issuing Bank shall prevail in such litigation)), and none of the Banks (including the Issuing Bank) nor the Administrative Agent nor any of their officers or
directors or employees or agents shall be liable or responsible, by reason of or in connection with the execution and delivery or transfer of or payment or failure to pay under any Letter of Credit, including without limitation any of the
circumstances enumerated in subsection 2.15(e) above, as well as (i) any error, omission, interruption or delay in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise, (ii) any loss or delay in the
transmission of any document required in order to make a drawing under a Letter of Credit and (iii) any consequences arising from causes beyond the control of the Issuing Bank, including, without limitation, any government acts or any other
circumstances whatsoever, in making or failing to make payment under such Letter of Credit; provided that the Borrower shall not be required to indemnify the Issuing Bank for any claims, damages, losses, liabilities, costs or expenses, and
the Borrower shall 

  

 12 








 
have a claim for direct (but not consequential) damage suffered by it, to the extent found by a court of competent jurisdiction to have been caused by (x) the
willful misconduct or gross negligence of the Issuing Bank in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit or (y) the Issuing Bank’s failure to pay under any Letter of
Credit after the presentation to it of a request strictly complying with the terms and conditions of the Letter of Credit. Nothing in this subsection 2.15(f) is intended to limit the obligations of the Borrower under any other provision of this
Agreement. To the extent the Borrower does not indemnify the Issuing Bank as required by this subsection, the Banks agree to do so ratably in accordance with their Commitments. 
 (g) The Issuing Bank shall act on behalf of the Banks with respect to any Letters of Credit issued by it and the documents associated therewith, and
the Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in Article 7 (other than Sections 7.08 and 7.09) with respect to any acts taken or omissions suffered by the Issuing Bank in connection with
Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term “Administrative Agent” as used in Article 7 included the
Issuing Bank with respect to such acts or omissions and (ii) as additionally provided herein with respect to the Issuing Bank. 
 Section 2.16. Regulation D Compensation. In the event that a Bank is required to maintain reserves of the type contemplated by the definition of “Euro-Dollar Reserve Percentage”, such Bank may require the
Borrower to pay, contemporaneously with each payment of interest on the Euro-Dollar Loans, additional interest on the related Euro-Dollar Loan of such Bank at a rate per annum determined by such Bank up to but not exceeding the excess of
(i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London Interbank Offered Rate. Any Bank wishing to require payment of such
additional interest (x) shall so notify the Borrower and the Administrative Agent, in which case such additional interest on the Euro-Dollar Loans of such Bank shall be payable to such Bank at the place indicated in such notice with respect to
each Interest Period commencing at least three Euro-Dollar Business Days after the giving of such notice and (y) shall notify the Borrower at least three Euro-Dollar Business Days prior to each date on which interest is payable on the
Euro-Dollar Loans of the amount then due it under this Section. Each such notification shall be accompanied by such information as the Borrower may reasonably request. 
 “Euro-Dollar Reserve Percentage” means for any day that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for determining the maximum reserve requirement for a member bank of the Federal Reserve System in New York City with deposits exceeding five billion dollars in respect of “Eurocurrency liabilities” (or in respect of any
other category of liabilities which includes deposits by reference to which the interest rate on Euro-Dollar Loans is determined or any category of extensions of credit or other assets which includes loans by a non-United States office of any Bank
to United States residents). 
 Section 2.17. Increase In Commitments; Additional Banks. (a) Subsequent to the Effective Date, Cinergy
may, upon at least 30 days’ notice to the Administrative Agent (which shall promptly provide a copy of such notice to the Banks), propose to increase the aggregate amount of the Commitments, provided that after giving effect to any such
increase, the total Commitments shall not exceed $2,500,000,000 (the amount of any such increase, the “Increased Commitments”). Each Bank party to this Agreement at such time shall have the right (but no obligation), for a period of
15 days following receipt of such notice, to elect by notice to Cinergy and the Administrative Agent to increase its Commitment hereunder. 
 (b) If any Bank party to this Agreement shall not elect to increase its Commitment pursuant to subsection (a) of this Section, Cinergy may designate another bank or other lenders (which may be, but need not be, one or more of the
existing Banks) which at the time agree to (i) in the case of any such lender that is an existing Bank, increase its Commitment and (ii) in the case of any other such lender (an “Additional Bank”), become a party to this
Agreement. The sum of the increases in the Commitments of the existing Banks pursuant to this subsection (b) plus the Commitments of the Additional Banks shall not in the aggregate exceed the unsubscribed amount of the Increased Commitments.

 (c) An increase in the aggregate amount of the Commitments pursuant to this Section 2.17 shall become effective upon the receipt
by the Administrative Agent of an agreement in form and substance satisfactory to the Administrative Agent signed by the Borrowers, by each Additional Bank and by each other Bank whose Commitment is to be increased, setting forth the new Commitments
of such Banks and setting forth the agreement of each Additional Bank to become a party to this Agreement and to be bound by all the terms and provisions hereof, together with such evidence of appropriate corporate authorization on the part of the
Borrower with respect to the Increased Commitments and such opinions of counsel for the Borrower with respect to the Increased Commitments as the Administrative Agent may reasonably request. 
 Upon any increase in the aggregate amount of the Commitments pursuant to this Section 2.17, (i) the respective Letter of Credit Liabilities of the Banks shall be
redetermined as of the effective date of such increase and (ii) within five Domestic Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current Interest Period with respect thereto, in the case of any
Euro-Dollar Loans then outstanding, the Borrower shall prepay such Group of Loans in its entirety and, to the extent the Borrower elects 

  

 13 








 
to do so and subject to the conditions specified in Article 3, the Borrower shall reborrow Revolving Credit Loans from the Banks in proportion to their respective
Commitments after giving effect to such increase, until such time as all outstanding Revolving Credit Loans are held by the Banks in such proportion.

to the insurance so carried. 
 Section 5.04. Maintenance of Existence. Such Borrower will preserve, renew and keep in full force and

of their respective businesses; provided that nothing in this Section 5.04 shall prohibit the termination of any right, privilege or franchise of such Borrower or any such Material Subsidiary or of the corporate or other legal existence
of any such Material Subsidiary, or the change in form of organization of such Borrower or any such Material Subsidiary, if such Borrower in good faith determines that such termination or change is in the best interest of such Borrower, is not
materially disadvantageous to the Banks and, in the case of a change in the form of organization of such Borrower, the Administrative Agent has consented thereto. 
 Section 5.05. Compliance with Laws. Such Borrower will comply, and cause each of its Material Subsidiaries to comply, in all material respects with all applicable laws, ordinances, rules, regulations, and
requirements of governmental authorities (including, without limitation, ERISA and Environmental Laws) except where (i) noncompliance would not have a material adverse effect on the business, financial position or results of operations of such
Borrower and its Consolidated Subsidiaries, considered as a whole, or (ii) the necessity of compliance therewith is contested in good faith by appropriate proceedings. 
 Section 5.06. Books and Records. Such Borrower will keep, and will cause each of its Material Subsidiaries to keep, proper books of record and account
in which full, true and correct entries shall be made of all financial transactions in relation to its business and activities in accordance with its customary practices; and will permit, and will cause each such Material Subsidiary to permit,
representatives of any Bank at such Bank’s expense (accompanied by a representative of such Borrower, if such Borrower so desires) to visit any of their respective properties, to examine any of their respective books and records and to discuss

 ARTICLE 7 
 THE ADMINISTRATIVE AGENT 
  
 Section 7.01. Appointment and Authorization. Each Bank irrevocably appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the
Notes as are delegated to the Administrative Agent by the terms hereof or thereof, together with all such powers as are reasonably incidental thereto. 
 Section 7.02. Administrative Agent and Affiliates. Barclays shall have the same rights and powers under this Agreement as any other Bank and may exercise or refrain from exercising the same as though it were not the
Administrative Agent, and Barclays. and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with any Borrower or any Subsidiary or affiliate of any Borrower as if it were not the Administrative Agent
hereunder. 
 Section 7.03. Action by Administrative Agent. The obligations of the Administrative Agent hereunder are only those expressly
set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action with respect to any Default, except as expressly provided in Article 6. 
 Section 7.04. Consultation with Experts. The Administrative Agent may consult with legal counsel (who may be counsel for a Borrower), independent public
accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. 
 Section 7.05. Liability of Administrative Agent. Neither the Administrative Agent nor any of its affiliates nor any of their respective directors,
officers, agents or employees shall be liable to any Bank for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Required Banks or (ii) in the absence of its own gross negligence or
willful misconduct. Neither the Administrative Agent nor any of its affiliates nor any of their respective directors, officers, agents or employees shall be responsible for or 

  

 20

notice, consent, certificate, statement, or other writing (which may be a bank wire, telex or similar writing) believed by it in good faith to be genuine or to be signed by the proper party or parties. Without limiting the generality of the
foregoing, the use of the term “agent” in this Agreement with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom and is intended to create or reflect only an administrative relationship between independent contracting parties. 
 Section 7.06. Indemnification. Each Bank shall, ratably in accordance with its Commitment, indemnify the Administrative Agent, its affiliates and their
respective directors, officers, agents and employees (to the extent not reimbursed by the Borrowers) against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such
indemnitees’ gross negligence or willful misconduct) that such indemnitees may suffer or incur in connection with this Agreement or any action taken or omitted by such indemnitees thereunder. 
 Section 7.07. Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon any Agent or any other Bank, and based on
such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon any Agent or any other Bank, and
based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement.

Upon any such resignation, (i) Cinergy, with the consent of the Required Banks (such consent not to be unreasonably withheld or delayed), or (ii) if an Event of Default has occurred and is continuing, then the Required Banks, shall have
the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent gives notice of resignation,
then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $250,000,000. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested
with all the rights and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder; provided that if such successor Administrative Agent is appointed
without the consent of Cinergy, such successor Administrative Agent may be replaced by Cinergy with the consent of the Required Banks so long as no Event of Default has occurred and is continuing at the time. After any retiring Administrative
Agent’s resignation hereunder as Administrative Agent, the provisions of this Article shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent. 
 Section 7.09. Administrative Agent’s Fee. Cinergy shall pay to the Administrative Agent for its own account fees in the amounts and at the times

 ARTICLE 8 
 CHANGE IN CIRCUMSTANCES 
  
 Section 8.01. Basis for Determining Interest Rate Inadequate or Unfair. If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing: 
 (a) the Administrative Agent is advised by the Euro-Dollar Reference Banks that deposits in dollars (in the applicable
amounts) are not being offered to the Euro-Dollar Reference Banks in the relevant market for such Interest Period, or 
 (b) Banks
having 66 2/3% or more of the aggregate amount of the affected Loans advise the Administrative Agent that the London
Interbank Offered Rate as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Banks of funding their Euro-Dollar Loans for such Interest Period, 
 the Administrative Agent shall forthwith give notice thereof to the Borrowers and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, (i) the obligations of the Banks to make Euro-Dollar Loans or to continue or convert outstanding Loans as or into Euro-Dollar Loans shall be suspended and (ii) each outstanding Euro-Dollar
Loan shall be converted into a Base Rate Loan on the last day of the then current Interest Period applicable thereto. Unless the 

  

 21 








 
Borrower notifies the Administrative Agent at least one Domestic Business Day before the date of any Euro-Dollar Borrowing for which a Notice of Borrowing has
previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Base Rate Borrowing. 
 Section 8.02.
Illegality. If on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund any of its Euro-Dollar Loans and such Bank shall so notify the Administrative
Agent, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrowers, whereupon until such Bank notifies the Borrowers and the Administrative Agent that the circumstances giving rise to such suspension no longer
exist, the obligation of such Bank to make Euro-Dollar Loans, or to continue or convert outstanding Loans as or into Euro-Dollar Loans, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section, such Bank
shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not be otherwise disadvantageous to such Bank in the good faith exercise of its discretion. If such notice is given, each
Euro-Dollar Loan of such Bank then outstanding shall be converted to a Base Rate Loan either (a) on the last day of the then current Interest Period applicable to such Euro-Dollar Loan if such Bank may lawfully continue to maintain and fund
such Loan to such day or (b) immediately if such Bank shall determine that it may not lawfully continue to maintain and fund such Loan to such day. 
 Section 8.03. Increased Cost and Reduced Return. (a) If on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change
in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (the terms “Bank” and “Issuing
Bank” shall include, for purposes of this Section 8.03, the holding company of any Issuing Bank) (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) issued on or after such date of any
such authority, central bank or comparable agency shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal
Reserve System, but excluding with respect to any Euro-Dollar Loan any such requirement included in an applicable Euro-Dollar Reserve Percentage) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its
Applicable Lending Office) or shall impose on any Bank (or its Applicable Lending Office) or on the London interbank market any other condition (other than in respect of Taxes or Other Taxes) affecting its Euro-Dollar Loans, its Note or its
obligation to make Euro-Dollar Loans or its obligations hereunder in respect of Letters of Credit and the result of any of the foregoing is to increase the cost to such Bank (or its Applicable Lending Office) of making or maintaining any Euro-Dollar
Loan or of issuing or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Note with respect thereto, by an amount deemed
by such Bank to be material, then, within 15 days after demand by such Bank (with a copy to the Administrative Agent), each Borrower shall pay to such Bank its Appropriate Share of such additional amount or amounts as will compensate such Bank for
such increased cost or reduction; provided that no such amount shall be payable with respect to any period commencing more than 90 days prior to the date such Bank first notifies the Borrowers of its intention to demand compensation therefor
under this Section 8.03(a). 
 (b) If any Bank shall have determined that, on or after the date of this Agreement, the adoption of
any applicable law, rule or regulation regarding capital adequacy, or any change in any such law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency given or made after the date of this
Agreement, has or would have the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank’s obligations hereunder to a level below that which such Bank (or its Parent) could have achieved but
for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within 15 days after demand by such Bank (with a copy
to the Administrative Agent), each Borrower shall pay to such Bank its Appropriate Share of such additional amount or amounts as will compensate such Bank (or its Parent) for such reduction; provided that no such amount shall be payable with
respect to any period commencing less than 30 days after the date such Bank first notifies the Borrowers of its intention to demand compensation under this Section 8.03(b). 
 (c) Each Bank will promptly notify the Borrowers and the Administrative Agent of any event of which it has knowledge, occurring after the date
hereof, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. 
  

 22 








 (d) The “Appropriate Share” of a Borrower with respect to any amount payable
hereunder is the sum of (i) to the extent such amount is properly allocable to Loans and Letters of Credit outstanding hereunder, the portion of such amount properly allocable to the Loans and Letter of Credit outstanding to or for the account
of such Borrower, and (ii) to the extent such amount is not properly allocable to Loans and Letters of Credit outstanding hereunder, the Appropriate Share shall be the product of the Availability Percentage of such Borrower and such amount.

income tax convention or treaty to which the United States is a party. 
 (b) Any and all payments by any Borrower to or for the account
of any Bank or the Administrative Agent hereunder or under any Note shall be made without deduction for any Taxes or Other Taxes; provided that, if any Borrower shall be required by law to deduct any Taxes or Other Taxes from any such

liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be paid within 15 days after such Bank or the Administrative Agent (as the case may be) makes demand therefor. 

(d) Each Bank organized under the laws of a jurisdiction outside the United States, on or prior to the date of its execution and delivery of this

tax on payments of interest for the account of such Bank or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of a trade or business in the United States. 
 (e) For any period with respect to which a Bank has failed to provide the Borrowers with the appropriate form pursuant to Section 8.04(d)
(unless such failure is due to a U.S. Tax Law Change), such Bank shall not be entitled to indemnification under Section 8.04(b) or 8.04(c) with respect to any Taxes or Other Taxes which would not have been payable had such form been so
provided; provided that if a Bank, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrowers shall take such steps as
such Bank shall reasonably request to assist such Bank to recover such Taxes (it being understood, however, that the Borrowers shall have no liability to such Bank in respect of such Taxes). 
  

 23 








 (f) If any Borrower is required to pay additional amounts to or for the account of any Bank
pursuant to this Section 8.04, then such Bank will take such action (including changing the jurisdiction of its Applicable Lending Office) as in the good faith judgment of such Bank (i) will eliminate or reduce any such additional payment
which may thereafter accrue and (ii) is not otherwise disadvantageous to such Bank. 
 (g) If any Bank or the Administrative Agent
receives a refund (including a refund in the form of a credit against taxes that are otherwise payable by the Bank or the Administrative Agent) of any Taxes or Other Taxes for which any Borrower has made a payment under Section 8.04(b) or
(c) and such refund was received from the taxing authority which originally imposed such Taxes or Other Taxes, such Bank or the Administrative Agent agrees to reimburse such Borrower to the extent of such refund; provided that nothing
contained in this paragraph (g) shall require any Bank or the Administrative Agent to seek any such refund or make available its tax returns (or any other information relating to its taxes which it deems to be confidential). 
 Section 8.05. Base Rate Loans Substituted for Affected Euro-Dollar Loans. If (i) the obligation of any Bank to make or to continue or convert
outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation under Section 8.03(a) or 8.04 with respect to its Euro-Dollar Loans and the Borrower shall, by at
least five Euro-Dollar Business Days’ prior notice to such Bank through the Administrative Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrowers that the
circumstances giving rise to such suspension or demand for compensation no longer apply: 
 (a) all Loans which would otherwise be made
by such Bank as (or continued as or converted to) Euro-Dollar Loans, as the case may be, shall instead be Base Rate Loans (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Banks), and

 (b) after each of its Euro-Dollar Loans has been repaid, all payments of principal which would otherwise be applied to repay such
Loans shall be applied to repay its Base Rate Loans instead. 
 If such Bank notifies the Borrowers that the circumstances giving rise to such suspension or demand for
compensation no longer exist, the principal amount of each such Base Rate Loan shall be converted into a Euro-Dollar Loan on the first day of the next succeeding Interest Period applicable to the related Euro-Dollar Loans of the other Banks.

 Section 8.06. Substitution of Bank; Termination Option. If (i) the obligation of any Bank to make or to convert or continue
outstanding Loans as or into Euro-Dollar Loans has been suspended pursuant to Section 8.02, (ii) any Bank has demanded compensation under Section 8.03 or 8.04, (iii) any Bank exercises its right not to extend its Commitment
Termination Date pursuant to Section 2.01(c) or (iv) Investment Grade Status ceases to exist as to any Bank, then: 
 (a)
Cinergy shall have the right, with the assistance of the Administrative Agent, to designate a substitute bank or banks (which may be one or more of the Banks) mutually satisfactory to Cinergy, the Administrative Agent and the Issuing Banks (whose
consent shall not be unreasonably withheld or delayed) to purchase for cash, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D hereto, the outstanding Loans of such Bank and assume the Commitment and Letter of
Credit Liabilities of such Bank, without recourse to or warranty by, or expense to, such Bank, for a purchase price equal to the principal amount of all of such Bank’s outstanding Loans and funded Letter of Credit Liabilities plus any accrued
but unpaid interest thereon and the accrued but unpaid fees in respect of such Bank’s Commitment hereunder and all other amounts payable by the Borrowers to such Bank hereunder plus such amount, if any, as would be payable pursuant to
Section 2.13 if the outstanding Loans of such Bank were prepaid in their entirety on the date of consummation of such assignment; and 
 (b) if at the time Investment Grade Status exists as to the Borrowers, Cinergy may elect to terminate this Agreement as to such Bank; provided that (i) Cinergy notifies such Bank through the Administrative Agent of such election
at least three Euro-Dollar Business Days before the effective date of such termination, (ii) the Borrowers repay or prepay the principal amount of all outstanding Loans made by such Bank plus any accrued but unpaid interest thereon and the
accrued but unpaid fees in respect of such Bank’s Commitment hereunder plus all other amounts payable by the Borrower to such Bank hereunder, not later than the effective date of such termination and (iii) if at the effective date of such
termination, any Letter of Credit Liabilities are outstanding, the conditions specified in Section 3.02 would be satisfied (after giving effect to such termination) were the related Letters of Credit issued on such date. Upon satisfaction of
the foregoing conditions, the Commitment of such Bank shall terminate on the effective date specified in such notice, its participation in any outstanding Letters of Credit shall terminate on such effective date and the participations of the other
Banks therein shall be redetermined as of such date as if such Letters of Credit had been issued on such date. 
  

 24 








 ARTICLE 9 
 MISCELLANEOUS 
  
 Section 9.01. Notices. All notices, requests and other communications to any party hereunder shall be in writing (including bank wire, telex, facsimile
transmission or similar writing) and shall be given to such party: (x) in the case of any Borrower or the Administrative Agent, at its address or telecopy or telex number set forth on the signature pages hereof, (y) in the case of any
Bank, at its address or telecopy or telex number set forth in its Administrative Questionnaire or (z) in the case of any party, such other address or telecopy or telex number as such party may hereafter specify for the purpose by notice to the
Administrative Agent and the Borrowers. Each such notice, request or other communication shall be effective (i) if given by telecopy or telex, when such telecopy or telex is transmitted to the telecopy or telex number specified in this Section
and the appropriate answerback or confirmation slip, as the case may be, is received or (ii) if given by any other means, when delivered at the address specified in this Section; provided that notices to the Administrative Agent or any
Issuing Bank under Article 2 or Article 8 shall not be effective until delivered. 
 Section 9.02. No Waivers. No failure or delay by the
Administrative Agent or any Bank in exercising any right, power or privilege hereunder or under any Note shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. 
 Section 9.03. Expenses; Indemnification. (a) Each Borrower shall pay (i) its Appropriate Share of all reasonable out-of-pocket expenses of the Administrative Agent, including reasonable fees and
disbursements of special counsel for the Agents, in connection with the preparation of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default with respect to such Borrower hereunder and (ii) if
an Event of Default with respect to such Borrower occurs, all reasonable out-of-pocket expenses incurred by the Administrative Agent or any Bank, including reasonable fees and disbursements of counsel, in connection with such Event of Default and
collection and other enforcement proceedings resulting therefrom. 
 (b) Each Borrower agrees to indemnify each Agent and each Bank,
their respective affiliates and the respective directors, officers, agents and employees of the foregoing (each an “Indemnitee”) and hold each Indemnitee harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and disbursements of counsel, which may be incurred by such Indemnitee in connection with any investigative, administrative or judicial proceeding (whether or not such
Indemnitee shall be designated a party thereto) relating to or arising out of this Agreement or any actual or proposed use of proceeds of Loans hereunder, in each case to the extent of such Borrower’s Appropriate Share; provided that no
Indemnitee shall have the right to be indemnified hereunder for such Indemnitee’s own gross negligence or willful misconduct as determined by a court of competent jurisdiction. 
 Section 9.04. Sharing of Set-offs. Each Bank agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment
of a proportion of the aggregate amount then due with respect to the Loans and Letter of Credit Liabilities held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount then due with respect to the
Loans and Letter of Credit Liabilities held by such other Bank, the Bank receiving such proportionately greater payment shall purchase such participations in the Loans and Letter of Credit Liabilities held by the other Banks, and such other
adjustments shall be made, as may be required so that all such payments with respect to the Loans and Letter of Credit Liabilities held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the
right of any Bank to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of a Borrower other than its indebtedness under this Agreement. 
 Section 9.05. Amendments and Waivers. (a) Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or
waiver is in writing and is signed by each Borrower and the Required Banks (and, if the rights or duties of any Agent or any Issuing Bank are affected thereby, by such Person); provided that no such amendment or waiver shall (x) unless
signed by each affected Bank, (i) increase the Commitment of any Bank or subject any Bank to any additional obligation, (ii) reduce the principal of or rate of interest on any Loan or the amount to be reimbursed in respect of any Letter of
Credit or any interest thereon or any fees hereunder or (iii) postpone the date fixed for any payment of principal of or interest on any Loan or for reimbursement in respect of any Letter of Credit or interest thereon or any fees hereunder or
for termination of any Commitment or (y) unless signed by all Banks, (i) change the definition of Required Banks or the provisions of this Section 9.05 or (ii) change the provisions of Section 9.04. 
 (b) This Agreement may be amended by Cinergy to remove any of CG&E, PSI Energy or ULH&P as a Borrower (a “Removed
Borrower”) hereunder subject to: (i) the receipt by the Administrative Agent of prior written notification from Cinergy of such amendment, (ii) repayment in full of all Loans made to such Borrower, (iii) cash
collateralization of all amounts available for drawing under Letters of Credit issued for the account of such Borrower (or the amendment of such Letter of Credit to provide for Cinergy as the account party) and (iv) repayment in full of all
other amounts owing by such Borrower under this Agreement (it being agreed that any such repayment shall be in accordance with the other terms of this Agreement). Upon the satisfaction of the foregoing 

  

 25 








 
conditions the rights and obligations of such Removed Borrower hereunder shall terminate; provided, however, that the obligations of such Removed Borrower under
Section 9.03 shall survive such amendment. 
 Section 9.06. Successors and Assigns. (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 and each Indemnitee, except that no Borrower may assign or otherwise transfer any of its rights under this Agreement without the prior
written consent of all Banks. 
 (b) Any Bank may, with the consent (unless an Event of Default then exists) of Cinergy (such consent
not to be unreasonably withheld or delayed), at any time grant to one or more banks or other institutions (each a “Participant”) participating interests in its Commitment or any or all of its Loans and Letter of Credit Liabilities;
provided that any Bank may, without the consent of any Borrower, at any time grant participating interests in its Commitment or any or all of its Loans and Letter of Credit Liabilities to another Bank, an Approved Fund or an Affiliate of such
transferor Bank. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Administrative Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and
the Borrowers, the Issuing Banks and the Administrative Agent shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement. Any agreement pursuant to which any Bank may
grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrowers hereunder including, without limitation, the right to approve any amendment, modification or
waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (x) (i), (ii) or
(iii) of Section 9.05(a) without the consent of the Participant. Each Borrower agrees that each Participant shall, to the extent provided in its participation agreement, be entitled to the benefits of Article 8 with respect to its
participating interest, subject to the performance by such Participant of the obligations of a Bank thereunder. An assignment or other transfer which is not permitted by subsection (c) or (d) below shall be given effect for purposes of
this Agreement only to the extent of a participating interest granted in accordance with this subsection (b). 
 (c) Any Bank may at any
time assign to one or more banks or other financial institutions (each an “Assignee”) all, or a proportionate part (equivalent to an initial Commitment of not less than $10,000,000 (unless Cinergy and the Administrative Agent shall
otherwise agree)) of all, of its rights and obligations under this Agreement and its Note (if any), and such Assignee shall assume such rights and obligations, pursuant to an Assignment and Assumption Agreement in substantially the form of Exhibit D
hereto executed by such Assignee and such transferor Bank, with (and only with and subject to) the prior written consent of the Issuing Banks, the Administrative Agent (which shall not be unreasonably withheld or delayed) and, so long as no Event of
Default has occurred and is continuing, Cinergy (which shall not be unreasonably withheld or delayed); provided that unless such assignment is of the entire right, title and interest of the transferor Bank hereunder, after making any such
assignment such transferor Bank shall have a Commitment of at least $10,000,000 (unless Cinergy and the Administrative Agent shall otherwise agree). Upon execution and delivery of such instrument of assumption and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set
forth in such instrument of assumption, and the transferor Bank shall be released from its obligations hereunder to a corresponding extent, and no further consent or action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Administrative Agent and the Borrowers shall make appropriate arrangements so that, if required by the Assignee, a Note(s) is issued to the Assignee. If the Assignee is not incorporated under
the laws of the United States of America or a state thereof, it shall, prior to the first date on which interest or fees are payable hereunder for its account, deliver to the Borrowers and the Administrative Agent certification as to exemption from
deduction or withholding of any United States federal income taxes in accordance with Section 8.04. All assignments (other than assignments to Affiliates) shall be subject to a transaction fee established by, and payable by the transferor Bank
to, the Administrative Agent for its own account (which shall not exceed $5,000). 
 (d) Any Bank may at any time assign all or any
portion of its rights under this Agreement and its Note (if any) to a Federal Reserve Bank. No such assignment shall release the transferor Bank from its obligations hereunder or modify any such obligations. 
 (e) No Assignee, Participant or other transferee of any Bank’s rights (including any Applicable Lending Office other than such Bank’s
initial Applicable Lending Office) shall be entitled to receive any greater payment under Section 8.03 or 8.04 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made by reason of
the provisions of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a different Applicable Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. 

Section 9.07. Collateral. Each of the Banks represents to the Administrative Agent and each of the other Banks that it in good faith is not relying
upon any “margin stock” (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement. 
  

 26 








 Section 9.08. Confidentiality. Each Agent and each Bank agrees to keep any information delivered or
made available by any Borrower pursuant to this Agreement confidential from anyone other than persons employed or retained by such Bank and its affiliates who are engaged in evaluating, approving, structuring or administering the credit facility
contemplated hereby; provided that nothing herein shall prevent any Bank from disclosing such information (a) to any other Bank or any Agent, (b) to any other Person if reasonably incidental to the administration of the credit
facility contemplated hereby, (c) upon the order of any court or administrative agency, (d) upon the request or demand of any regulatory agency or authority, (e) which had been publicly disclosed other than as a result of a disclosure
by any Agent or any Bank prohibited by this Agreement, (f) in connection with any litigation to which any Agent, any Bank or its subsidiaries or Parent may be a party, (g) to the extent necessary in connection with the exercise of any
remedy hereunder, (h) to such Bank’s or any Agent’s legal counsel and independent auditors and (i) subject to provisions substantially similar to those contained in this Section 9.08, to any actual or proposed Participant or
Assignee. 
 Section 9.09. Governing Law; Submission to Jurisdiction. This Agreement and each Note (if any) shall be construed in accordance
with and governed by the law of the State of New York. Each Borrower hereby submits to the nonexclusive jurisdiction of the United States District Court for the Southern District of New York and of any New York State court sitting in New York City
for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each Borrower irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to
the laying of the venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. 
 Section 9.10. Counterparts; Integration. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written,
relating to the subject matter hereof. 
 Section 9.11. WAIVER OF JURY TRIAL. EACH OF THE BORROWERS, THE AGENTS, THE ISSUING BANKS AND THE
BANKS, TO THE FULLEST EXTENT IT MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

 Section 9.12. USA Patriot Act. Each Bank hereby notifies each Borrower that pursuant to the requirements of the USA Patriot Act, Title
III of Pub. L. 107-56 (signed into law October 26, 2001) (the “Act”), it is required to obtain, verify and record information that identifies such Borrower, which information includes the name and address of such Borrower and
other information that will allow such Bank to identify such Borrower in accordance with the Act.

 The
“Utilization” applicable to any date is the percentage equivalent of a fraction the numerator of which is the sum of (i) the aggregate outstanding principal amount of the Loans to all Borrowers determined at such time after
giving effect, if one or more Loans are being made at such time, to any substantially concurrent application of the proceeds thereof to repay one or more other Loans plus (ii) the aggregate amount of the Letter of Credit Liabilities of all
Banks for the account of all Borrowers at such time and the denominator of which is the aggregate amount of the Commitments at such date. If for any reason any Loans or Letter of Credit Liabilities remain outstanding following termination of the
Commitments, Utilization will be deemed to be 100%. 
 The Facility Fee Rate at any date shall be determined on the basis of the credit ratings of
Cinergy at such date, while the Euro-Dollar Margin applicable at any date for purposes of calculating interest on a Loan or fees in respect of a Letter of Credit shall be based upon the credit ratings of the Borrower to which such Loan is
outstanding or for whose account such Letter of Credit was issued. The credit ratings to be utilized for purposes of this Schedule are those indicated for or assigned to the senior unsecured long-term debt securities of the relevant Borrower without
third-party credit enhancement, and any rating indicated for or assigned to any other debt security of such Borrower shall be disregarded. The ratings in effect for any day are those in effect at the close of business on such day. A change in credit
rating will result in an immediate change in the applicable pricing. In the case of split ratings from S&P and Moody’s, the rating to be used to determine the applicable pricing is a rating one notch higher than the lower of the two.

 EXHIBIT B-1 
 OPINION OF INTERNAL COUNSEL OF THE BORROWER 
  
 [Effective Date]

 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Barclays Bank PLC 
 as Administrative Agent 
 200 Park Avenue 
 New York, New York
10166 
  
 Ladies and Gentlemen: 
 I am [title of internal counsel] of [Cinergy Corp.] [The Cincinnati Gas & Electric Company] [PSI Energy, Inc.] [The Union Light, Heat and Power Company]
(the “Borrower”) and have acted as its counsel in connection with the Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of June 29, 2006, among Cinergy Corp., The Cincinnati
Gas & Electric Company, PSI Energy, Inc., The Union Light, Heat and Power Company (together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the “Borrowers”), the banks listed on the
signature pages thereof, Barclays Bank PLC, as Administrative Agent, and JPMorgan Chase Bank, N.A., as Syndication Agent. Capitalized terms defined in the Credit Agreement are used herein as therein defined. This opinion letter is being delivered
pursuant to Section 3.01(b) of the Credit Agreement. 
 In such capacity, I or attorneys under my direct supervision have examined originals or
copies, certified or otherwise identified to my satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as I have deemed necessary or
advisable for purposes of this opinion. 
 Upon the basis of the foregoing, I am of the opinion that: 
 1. The Borrower is [a Delaware] [an Ohio] [an Indiana] [a Kentucky] corporation, validly existing and in good standing under the laws of [Delaware]
[Ohio] [Indiana] [Kentucky]. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement and any Notes are
within the Borrower’s corporate powers, have been duly authorized by all necessary corporate action, require no action by or in respect of, or filing with, any governmental body, agency or official (except for [list exceptions], which have been
obtained or made, as the case may be, and are in full force and effect) and do not contravene, or constitute a default under, any provision of applicable law or regulation or of the articles of incorporation or by-laws of the Borrower or, to my
knowledge, of any agreement, judgment, injunction, order, decree or other instrument binding upon the Borrower or, to my knowledge, result in the creation or imposition of any Lien on any asset of the Borrower or any of its Material Subsidiaries.

 3. The Credit Agreement and any Notes executed and delivered as of the date hereof have been duly executed and delivered by the
Borrower. 
 4. Except as disclosed in the Borrower’s annual report on Form 10-K for the fiscal year ended December 31, 2005
and its quarterly report on Form 10-Q for the period ended March 31, 2006, to my knowledge (but without independent investigation), there is no action, suit or proceeding pending or threatened against or affecting, the Borrower or any of its
Subsidiaries before any court or arbitrator or any governmental body, agency or official, which would be likely to be decided adversely to the Borrower or such Subsidiary and, as a result, to have a material adverse effect upon the business,
consolidated financial position or consolidated results of operations of the Borrower and its Consolidated Subsidiaries, considered as a whole, or which in any manner draws into question the validity of the Credit Agreement or any Notes. 

The phrase “to my knowledge”, as used in the foregoing opinion, refers to my actual knowledge without any independent investigation as to any such
matters. 
 I am a member of the Bar of the State of [Delaware] [Ohio] [Indiana] [Kentucky] and do not express any opinion herein concerning any law
other than the law of the State of [Delaware] [Ohio] [Indiana] [Kentucky] and the federal law of the United States of America. 
 The opinions expressed
herein are limited to the matters expressly stated herein, and no opinion is to be inferred or may be implied beyond the matters expressly so stated. This opinion is rendered to you in connection with the above-referenced matter and may not be
relied upon by you for any other purpose, or relied upon by, or furnished to, any other Person, firm or corporation without my prior written consent, except for Additional Banks and Assignees. My opinions expressed herein are as of the date hereof,
and I undertake no obligation to advise you of any changes of applicable law or any other matters that may come to my attention after the date hereof that may affect my opinions expressed herein. 
  
 Very truly yours, 







 EXHIBIT B-2 
 OPINION OF 
 ROBINSON, BRADSHAW & HINSON, P.A., 
 SPECIAL COUNSEL FOR THE BORROWER 
  
 [Effective Date] 
 To the Banks and the Administrative Agent 
       Referred to Below 
 c/o Barclays Bank PLC 
       as Administrative Agent 
 200 Park Avenue 
 New York, New York 10166 
  
 Ladies and Gentlemen: 
 We have acted as counsel to [Cinergy Corp., a Delaware] [The Cincinnati Gas & Electric Company, an Ohio] [PSI Energy, Inc., an Indiana] [The Union Light,
Heat and Power Company, a Kentucky] corporation (the “Borrower”), in connection with the Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of June 29, 2006, among Cinergy Corp., The
Cincinnati Gas & Electric Company, PSI Energy, Inc., The Union Light, Heat and Power Company (together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the “Borrowers”), the banks
listed on the signature pages thereof, Barclays Bank PLC, as Administrative Agent, and JPMorgan Chase Bank, N.A., as Syndication Agent. Capitalized terms used herein and not defined shall have the meanings given to them in the Credit Agreement. This
opinion letter is being delivered pursuant to Section 3.01(b) of the Credit Agreement. 
 In connection with this opinion, we also examined
originals, or copies identified to our satisfaction, of such other documents and considered such matters of law and fact as we, in our professional judgment, have deemed appropriate to render the opinions contained herein. Where we have considered
it appropriate, as to certain facts we have relied, without investigation or analysis of any underlying data contained therein, upon certificates or other comparable documents of public officials and officers or other appropriate representatives of
the Borrower. 
 In rendering the opinions contained herein, we have assumed, among other things, that the Credit Agreement and any Notes to be executed
(i) are within the Borrower’s corporate powers, (ii) have been duly authorized by all necessary corporate action, (iii) have been duly executed and delivered, (iv) require no action by or in respect of, or filing with, any
governmental body, agency of official and (v) do not contravene, or constitute a default under, any provision of applicable law or regulation or of the Borrower’s certificate of incorporation or by-laws or any agreement, judgment,
injunction, order, decree or other instrument binding upon the Borrower or result in the creation or imposition of any Lien on any asset of the Borrower. In addition, we have assumed that the Credit Agreement fully states the agreement between the
Borrower and the Banks with respect to the matters addressed therein, and that the Credit Agreement constitutes a legal, valid and binding obligation of each Bank, enforceable in accordance with its respective terms. 
 The opinions set forth herein are limited to matters governed by the laws of the State of North Carolina and the federal laws of the United States, and no opinion
is expressed herein as to the laws of any other jurisdiction. For purposes of our opinions, we have disregarded the choice of law provisions in the Credit Agreement and, instead, have assumed with your permission that the Credit Agreement and the
Notes are governed exclusively by the internal, substantive laws and judicial interpretations of the State of North Carolina. We express no opinion concerning any matter respecting or affected by any laws other than laws that a lawyer in North
Carolina exercising customary professional diligence would reasonably recognize as being directly applicable to the Borrower, the Loans, or any of them. 
 Based upon and subject to the foregoing and the further limitations and qualifications hereinafter expressed, it is our opinion that the Credit Agreement constitutes the legal, valid and binding obligation of the Borrower and the Notes, if
and when issued, will constitute legal, valid and binding obligations of the Borrower, in each case, enforceable against the Borrower in accordance with its terms. 
 The opinions expressed above are subject to the following qualifications and limitations: 
 1. Enforcement of the
Credit Agreement and the Notes is subject to the effect of applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and similar laws affecting the enforcement of creditors’ rights generally. 
 2. Enforcement of the Credit Agreement and the Notes is subject to the effect of general principles of equity (regardless of whether considered in a
proceeding in equity or at law) by which a court with proper jurisdiction may deny rights of specific performance, injunction, self-help, possessory remedies or other remedies. 
 3. We do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement or any Note that (i) purport to
excuse a party for liability for its own acts, (ii) purport to make void any act done in contravention thereof, (iii) purport to authorize a party to act in its sole discretion, (iv) require waivers or amendments to be made only in
writing, (v) purport to effect waivers of constitutional, statutory or equitable rights or the effect of applicable laws, (vi) impose liquidated damages, penalties or forfeiture, or (vii) purport to indemnify a party for its own
negligence or willful misconduct. Indemnification provisions in the Credit Agreement are subject to and may be rendered unenforceable by applicable law or public policy, including applicable securities law. 







 4. We do not express any opinion as to the enforceability of any provisions contained in the Credit
Agreement or the Notes purporting to require a party thereto to pay or reimburse attorneys’ fees incurred by another party, or to indemnify another party therefor, which may be limited by applicable statutes and decisions relating to the
collection and award of attorneys’ fees, including but not limited to North Carolina General Statutes § 6-21.2. 
 5. We
do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement purporting to waive the right of jury trial. Under North Carolina General Statutes § 22B-10, a provision for the waiver of the right to
a jury trial is unconscionable and unenforceable. 
 6. We do not express any opinion as to the enforceability of any provisions
contained in the Credit Agreement concerning choice of forum or consent to the jurisdiction of courts, venue of actions or means of service of process. 
 7. It is likely that North Carolina courts will enforce the provisions of the Credit Agreement providing for interest at a higher rate resulting from a Default or Event of Default (a “Default Rate”) which
rate is higher than the rate otherwise stipulated in the Credit Agreement. The law, however, disfavors penalties, and it is possible that interest at the Default Rate may be held to be an unenforceable penalty, to the extent such rate exceeds the
rate applicable prior to a default under the Credit Agreement. Also, since North Carolina General Statutes § 24-10.1 expressly provides for late charges, it is possible that North Carolina courts, when faced specifically with the issue,
might rule that this statutory late charge preempts any other charge (such as default interest) by a bank for delinquent payments. The only North Carolina case which we have found that addresses this issue is a 1978 Court of Appeals decision, which
in our opinion is of limited precedential value, North Carolina National Bank v. Burnette, 38 N.C. App. 120, 247 S.E.2d 648 (1978), rev’d on other grounds, 297 N.C. 524, 256 S.E.2d 388 (1979). While the court in that case did
allow interest after default (commencing with the date requested in the complaint) at a rate six percent in excess of pre-default interest, we are unable to determine from the opinion that any question was raised as to this being penal in nature,
nor does the court address the possible question of the statutory late charge preempting a default interest surcharge. Therefore, since the North Carolina Supreme Court has not ruled in a properly presented case raising issues of its possible penal
nature and those of North Carolina General Statutes § 24-10.1, we are unwilling to express an unqualified opinion that the Default Rate of interest prescribed in the Credit Agreement is enforceable. 
 8. We do not express any opinion as to the enforceability of any provisions contained in the Credit Agreement relating to evidentiary standards or
other standards by which the Credit Agreement are to be construed. 
 This opinion letter is delivered solely for your benefit in connection with the
Credit Agreement and, except for any Additional Bank or any Assignee which becomes a Bank pursuant to Section 2.17 or 9.06(c) of the Credit Agreement, may not be used or relied upon by any other Person or for any other purpose without our prior
written consent in each instance. Our opinions expressed herein are as of the date hereof, and we undertake no obligation to advise you of any changes of applicable law or any other matters that may come to our attention after the date hereof that
may affect our opinions expressed herein. 
  
 Very truly
yours,

 FOR THE AGENTS
  
 [Effective

 To the Banks and the Administrative Agent 
   Referred to Below

 c/o Barclays Bank PLC, 
 as Administrative Agent 
 200 Park Avenue 
 New York, New York 10166 
  
 Dear Sirs: 
 We have participated in the preparation of the Amended and Restated Credit Agreement (the “Credit Agreement”) dated as of June 29, 2006 among Cinergy Corp., a Delaware corporation, The Cincinnati Gas &
Electric Company, an Ohio corporation, PSI Energy, Inc., an Indiana corporation, The Union Light, Heat and Power Company, a Kentucky corporation (together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the
“Borrowers”, each individually, a “Borrower”), the banks listed on the signature pages thereof (the “Banks”), Barclays Bank PLC, as Administrative Agent (the “Administrative
Agent”), and JPMorgan Chase Bank, N.A., as Syndication Agent, and have acted as special counsel for the Agents for the purpose of rendering this opinion pursuant to Section 3.01(c) of the Credit Agreement. Terms defined in the Credit
Agreement are used herein as therein defined. 
 We have examined originals or copies, certified or otherwise identified to our satisfaction, of such
documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as we have deemed necessary or advisable for purposes of this opinion. 
 Upon the basis of the foregoing, we are of the opinion that: 
 1. The execution, delivery and performance by each Borrower of the Credit Agreement and the Notes are within such Borrower’s corporate powers and have been duly authorized by all necessary corporate action. 
 2. The Credit Agreement constitutes a valid and binding agreement of each Borrower and the Notes, if and when issued by a Borrower, constitute valid
and binding obligations of such Borrower enforceable in accordance with their respective terms, except as the same may be limited by bankruptcy, insolvency or similar laws affecting creditors’ rights generally and by general principles of
equity. 
 In giving the foregoing opinion, (i) we express no opinion as to the effect (if any) of any law of any jurisdiction (except the State of
New York) in which any Bank is located which limits the rate of interest that such Bank may charge or collect and (ii) we have relied, without independent investigation, as to all matters governed by the laws of each of Delaware, Ohio, Indiana
and Kentucky upon the opinion of the internal counsel of the Borrower located in such jurisdiction, dated [Effective Date], a copy of each of which has been delivered to you. 
 This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by or
furnished to any other person, firm or corporation without our prior written consent, except for Additional Banks and all Participants. 
  
 Very truly yours,

(together with Cinergy Corp., The Cincinnati Gas & Electric Company and PSI Energy, Inc., the “Borrowers”, each individually, a “Borrower”), the Assignor and the other Banks party thereto, as Banks, the
Administrative Agent and JPMorgan Chase Bank, N.A., as Syndication Agent (the “Credit Agreement”); 
 WHEREAS, as provided under the
Credit Agreement, the Assignor has a Commitment to make Loans to the Borrowers and participate in Letters of Credit in an aggregate principal amount at any time outstanding not to exceed

 WHEREAS, Loans made to the Borrowers by the Assignor under the

thereunder in an amount equal to $            (the “Assigned Amount”), together with a corresponding portion of its outstanding Loans and Letter of Credit Liabilities, and
the Assignee proposes to accept assignment of such rights and assume the corresponding obligations from the Assignor on such terms;* 
 NOW, THEREFORE,
in consideration of the foregoing and the mutual agreements contained herein, the parties hereto agree as follows: 
 SECTION 1.
Definitions. All capitalized terms not otherwise defined herein shall have the respective meanings set forth in the Credit Agreement. 
 SECTION 2. Assignment. The Assignor hereby assigns and sells to the Assignee all of the rights of the Assignor under the Credit Agreement to the extent of the Assigned Amount, and the Assignee hereby accepts such
assignment from the Assignor and assumes all of the obligations of the Assignor under the Credit Agreement to the extent of the Assigned Amount, including the purchase from the Assignor of the corresponding portion of the principal amount of the
Loans made by, and Letter of Credit Liabilities of, the Assignor outstanding at the date hereof. Upon the execution and delivery hereof by the Assignor, the Assignee [, Cinergy Corp.] [, the Issuing Banks] and the Administrative Agent, the payment
of the amounts specified in Section 3 required to be paid on the date hereof (i) the Assignee shall, as of the date hereof, succeed to the rights and be obligated to perform the obligations of a Bank under the Credit Agreement with a
Commitment in an amount equal to the Assigned Amount, and (ii) the Commitment of the Assignor shall, as of the date hereof, be reduced by a like amount and the Assignor released from its obligations under the Credit Agreement to the extent such
obligations have been assumed by the Assignee. The assignment provided for herein shall be without recourse to the Assignor. 
 SECTION 3. Payments. As consideration for the assignment and sale contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the date hereof in Federal funds the amount heretofore agreed
between them.2 It is understood that facility [and Letter of Credit] fees accrued to the date hereof in respect of the Assigned Amount are for the account of the Assignor and such fees accruing from and including the date

of such other party to the extent of such other party’s interest therein and shall promptly pay the same to such other party. 
 SECTION 4. Consent to Assignment. This Agreement is conditioned upon the consent of [Cinergy Corp.,] [the Issuing Banks] and the Administrative Agent pursuant to Section 9.06(c) of the Credit Agreement. The
execution of this Agreement by [Cinergy Corp.,] [the Issuing Banks] and the Administrative Agent is evidence of this consent. Pursuant to Section 9.06(c) each Borrower agrees to execute and deliver a Note, if required by the Assignee, payable
to the order of the Assignee to evidence the assignment and assumption provided for herein. 
 SECTION 5. Non-reliance on
Assignor. The Assignor makes no representation or warranty in connection with, and shall have no responsibility with respect to, the solvency, financial condition, or statements of any Borrower, or the validity and enforceability of the
obligations of any Borrower in respect of the Credit Agreement or any Note. The Assignee acknowledges that it has, independently and without reliance on the Assignor, and based on such documents and information as it has deemed appropriate, made its
own credit 

  


	1	The asterisked provisions shall be appropriately revised in the event of an assignment after the Commitment Termination Date. 


	2	Amount should combine principal together with accrued interest and breakage compensation, if any, to be paid by the Assignee. It may be preferable in an appropriate case to specify these
amounts generically or by formula rather than as a fixed sum. 









 
analysis and decision to enter into this Agreement and will continue to be responsible for making its own independent appraisal of the business, affairs and financial
condition of each Borrower. 
 SECTION 6. Governing Law. This Agreement shall be governed by and construed in accordance with

 SECTION 7. Counterparts. This Agreement may be signed in any number of counterparts,
each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.
