ARTICLE 2
The Credits
     Section 2.01. Commitments to Lend. During the 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 Section from time to time;
provided that, immediately after each such loan is made, the Utilization Limits
are not exceeded. Each Borrowing shall be in an aggregate principal amount of
$5,000,000 or any larger multiple of $1,000,000 and shall be made from the
several Banks ratably in proportion to their respective Commitments in effect on
the date of Borrowing. Within the foregoing limits, the Borrowers may borrow
under this Section, or to the extent permitted by Section 2.11, prepay Loans and
reborrow at any time during the Revolving Credit Period under this Section.
     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.
(Eastern 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 Base Rate 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;
     (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; and
     (e) if applicable, the designation contemplated by the definition of
Maturity Date.
     Section 2.03. Notice to Banks; Funding of Loans. (a) Upon receipt (or
deemed 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. (Eastern time) on the date of each Borrowing,
each Bank shall (except as provided in subsection (c) of this Section) make
available its share of such Borrowing, in Federal or other immediately

13

--------------------------------------------------------------------------------

 

available funds, 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 by 2:00 P.M. (Eastern time) at the Administrative Agent’s aforesaid
address.
     (c) Unless the Administrative Agent shall have received notice from a Bank
prior to 1:00 P.M. (Eastern time) on 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 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

14

--------------------------------------------------------------------------------

 

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 either 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. Each Loan made by any Bank shall mature,
and the principal amount thereof shall be due and payable together with accrued
interest thereon, on the Maturity Date applicable to such Loan.
     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 sum of the
Applicable Margin for such day plus 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 Applicable 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 Reuters’ Page LIBOR-01 (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
Reuters, as may be nominated by the Administrative Agent in consultation with
the Borrowers for such purpose) as of 11:00 A.M. (London time) two Euro-Dollar
Business Days prior to the commencement of such Interest Period, as the rate for

15

--------------------------------------------------------------------------------

 

U.S. dollar deposits with a maturity comparable to such Interest Period. In the
event that no such rate is available at such time for any reason, then 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
Applicable 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 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) Unused Commitment Fees. The Borrowers shall pay to
the Administrative Agent, for the account of the Banks (but not for the account
of any Affected Bank), ratably, an unused commitment fee on the daily average
amount by which the aggregate amount of the Commitments exceeds the aggregate
outstanding principal amount of the Loans, accruing at the applicable rate per
annum specified in the Pricing Schedule; provided that the Company shall pay the
unused commitment fee on an amount equal to its Unused Sublimit and Duke Energy
Carolinas shall pay the balance of such fee. Such unused commitment fee shall
accrue for each day from and including the Effective Date but excluding the day
on which the related Borrower Exposures are reduced to zero.
     (b) 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
the Commitment Termination Date (and, if earlier, the date the Borrower Exposure
of such Bank in respect of either Borrower is reduced to zero).
     Section 2.08. Optional Termination or Reduction of Commitments. The Company
may, upon not less than three Domestic Business Days’ notice to the
Administrative Agent, terminate at any time, or reduce from time to time in
minimum amounts of $10,000,000 or incremental multiples of $5,000,000, the
aggregate unused amount of the Commitments. Each such reduction shall be applied
ratably to the Commitments of the several Banks. The Administrative Agent shall
promptly notify the Banks of any termination or reduction of the Commitments
pursuant to this Section.

16

--------------------------------------------------------------------------------

 

     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.
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. (Eastern
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 $5,000,000 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.

17

--------------------------------------------------------------------------------

 

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 the 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. (Eastern 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. (Eastern 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. (Eastern 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

18

--------------------------------------------------------------------------------

 

account of the Banks. Whenever any payment of principal of, or interest on, the
Base Rate Loans 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.
     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 Applicable 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 unused commitment fees hereunder shall be computed on the basis

19

--------------------------------------------------------------------------------

 

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).
Interest based on the Euro-Dollar Rate 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. 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

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 2.16. Increase in Commitments; Additional Banks. (a) Subsequent to
the Effective Date, the Company may increase the aggregate amount of the
Commitments in minimum increments of $1,000,000 up to five times by
(i) designating a financial institution not theretofore a Bank to become a an
Additional Bank (such designation to be effective only with the prior written
consent of the Administrative Agent, which consent will not be unreasonably
withheld or delayed) or (ii) by agreeing with an existing Bank that such Bank’s
Commitment shall be increased, provided that after giving effect to any such

20

--------------------------------------------------------------------------------

 

increase, the total Commitments shall not exceed $300,000,000 (the amount of any
such increase, the “Increased Commitments”).
     (b) An increase in the aggregate amount of the Commitments pursuant to this
Section 2.16 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
Borrowers with respect to the Increased Commitments and such opinions of counsel
for the Borrowers 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 2.16 within five Domestic Business Days, in the case of any Group of
Base Rate Loans then outstanding, and at the end of the then current Interest
Period with respect thereto, in the case of any Group of Euro-Dollar Loans then
outstanding, the Borrower shall prepay such Group of Loans in its entirety and,
to the extent the Borrower elects to do so and subject to the conditions
specified in Article 3, the Borrower shall reborrow Loans from the Banks in
proportion to their respective Commitments after giving effect to such increase,
until such time as all outstanding Loans are held by the Banks in such
proportion.

--------------------------------------------------------------------------------

 

     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

statement, warranty or representation made in connection with this Agreement or
any borrowing hereunder; (ii) the performance or observance of any of the
covenants or agreements of either Borrower; (iii) the satisfaction of any
condition specified in Article 3, except receipt of items required to be

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, penalties 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.
     Section 7.08. Successor Administrative Agent. The Administrative Agent may
resign at any time by giving notice thereof to the Banks and the Borrowers. Upon
any such resignation, (i) the Company, 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
the Company, such successor Administrative Agent may be replaced by the Company
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. The Borrowers shall pay to the
Administrative Agent for its own account fees in the amounts and at the times
previously agreed upon between the Borrowers and the Administrative Agent.
     Section 7.10. Other Agents. None of the Syndication Agent or the
Co-Documentation Agents, in their respective capacities as such, shall have any
duties or obligations of any kind under this Agreement.

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, 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
Borrowers 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 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

36

--------------------------------------------------------------------------------

 

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 term “Bank” shall include, for purposes
of this Section 8.03, the holding company of any 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 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 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

37

--------------------------------------------------------------------------------

 

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.
     (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 outstanding hereunder, the portion of such amount properly
allocable to the Loans outstanding to or for the account of such Borrower, and
(ii) to the extent such amount is not properly allocable to Loans outstanding
hereunder, the Appropriate Share shall be the product of the Availability
Percentage of such Borrower and such amount.
     Section 8.04. Taxes. (a) For purposes of this Section 8.04 the following
terms have the following meanings:
     “Taxes” means any and all present or future taxes, duties, levies, imposts,
deductions, charges or withholdings with respect to any payment by a Borrower
pursuant to this Agreement or any Note, and all liabilities with respect
thereto, excluding (i) in the case of each Bank and the Administrative Agent,
taxes imposed on its income, net worth or gross receipts and franchise or
similar taxes imposed on it by a jurisdiction under the laws of which such Bank
or the Administrative Agent (as the case may be) is organized or in which its
principal executive office is located or, in the case of each Bank, in which its
Applicable Lending Office is located and (ii) in the case of each Bank, any
United States withholding tax imposed on such payments except to the extent that
such Bank is subject to United States withholding tax by reason of a U.S. Tax
Law Change.

38

--------------------------------------------------------------------------------

 

     “Other Taxes” means any present or future stamp or documentary taxes and
any other excise or property taxes, or similar charges or levies, which arise
from any payment made pursuant to this Agreement or under any Note or from the
execution or delivery of, or otherwise with respect to, this Agreement or any
Note.
     “U.S. Tax Law Change” means with respect to any Bank or Participant the
occurrence (x) in the case of each Bank listed on the signature pages hereof,
after the date of its execution and delivery of this Agreement and (y) in the
case of any other Bank, after the date such Bank shall have become a Bank
hereunder, and (z) in the case of each Participant, after the date such
Participant became a Participant hereunder, of the adoption of any applicable
U.S. federal law, U.S. federal rule or U.S. federal regulation relating to
taxation, or any change therein, or the entry into force, modification or
revocation of any income tax convention or treaty to which the United States is
a party.
     (b) Any and all payments by either 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 either
Borrower shall be required by law to deduct any Taxes or Other Taxes from any
such payments, (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 8.04) such Bank or the Administrative Agent (as
the case may be) receives an amount equal to the sum it would have received had
no such deductions been made, (ii) such Borrower shall make such deductions,
(iii) such Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law and (iv) such
Borrower shall furnish to the Administrative Agent, at its address referred to
in Section 9.01, the original or a certified copy of a receipt evidencing
payment thereof.
     (c) Each Borrower agrees to indemnify each Bank and the Administrative
Agent for its Appropriate Share of the full amount of Taxes or Other Taxes
(including, without limitation, any Taxes or Other Taxes imposed or asserted by
any jurisdiction on amounts payable under this Section 8.04) paid by such Bank
or the Administrative Agent (as the case may be) and any 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 Agreement
in the case of each Bank listed on the signature pages hereof and on or prior to
the date on which it becomes a Bank in the case of each other Bank, and

39

--------------------------------------------------------------------------------

 

from time to time thereafter as required by law (but only so long as such Bank
remains lawfully able to do so), shall provide the Borrowers two completed and
duly executed copies of Internal Revenue Service form W-8BEN or W-8ECI, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
or other documentation reasonably requested by the Borrowers, certifying that
such Bank is entitled to benefits under an income tax treaty to which the United
States is a party which exempts the Bank from United States withholding tax or
reduces the rate of withholding 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).
     (f) If either 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 either
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

40

--------------------------------------------------------------------------------

 

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
becomes an Affected Bank or (iv) Investment Grade Status ceases to exist as to
any Bank that is rated, then:
     (a) the Borrowers 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 the Borrowers and the
Administrative Agent 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 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 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

41

--------------------------------------------------------------------------------

 

     (b) if at the time Investment Grade Status exists as to the Borrowers, the
Borrowers may elect to terminate this Agreement as to such Bank; provided that
(i) the Borrowers notify such Bank through the Administrative Agent of such
election at least three Euro-Dollar Business Days before the effective date of
such termination and (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 Borrowers to such Bank
hereunder, not later than the effective date of such termination. Upon
satisfaction of the foregoing conditions, the Commitment of such Bank shall
terminate on the effective date specified in such notice.
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 either 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 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

42

--------------------------------------------------------------------------------

 

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, penalties, 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 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 held by such other Bank,
the Bank receiving such proportionately greater payment shall purchase such
participations in the Loans 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 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; Conforming Changes. (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 are affected thereby,
by such Person); provided that no such amendment or waiver shall (x) unless
signed by each Bank affected thereby, (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 any interest thereon or any fees hereunder,
(iii) postpone the date fixed for any payment of principal of or interest on any
Loan or interest thereon or any fees hereunder or for termination of any
Commitment or

43

--------------------------------------------------------------------------------

 

(iv) impose a restriction on the ability of any Bank to assign its rights and
obligations hereunder or (y) unless signed by all Banks, (i) change the
definition of Required Banks or the provisions of this Section 9.05, (ii) change
the provisions of Section 9.04 or (iii) change any requirement for ratable
application of payments, including, without limitation, under Sections 2.11 and
2.12 of this Agreement.
     (b) If any representation or warranty in Article 4 of the Master Credit
Facility, any covenant in Article 5 of the Master Credit Facility or any event
of default in Article 6 of the Master Credit Facility and, in each case, any
related definitions in the Master Credit Facility, is replaced, changed,
amended, modified, supplemented or removed (any of the foregoing, a “Change”),
regardless of whether the Master Credit Facility is replaced, refinanced,
amended and restated, amended, modified or supplemented and regardless of
whether any such Change occurs in the corresponding article or definitions, such
Change shall be incorporated automatically into this Agreement upon the later of
(i) the effectiveness of such Change in the Master Credit Facility and (ii) the
30th day after the Administrative Agent’s receipt of notice from the Company of
such Change, provided that the Required Banks hereunder do not notify the
Company through the Administrative Agent within 30 days after the Administrative
Agent’s receipt of such notice from the Company of their election (which may be
made in their discretion) that such Change shall not be effective with respect
to this Agreement.
     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 the Company (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; provided
that the Company shall be deemed to have consented to any such participation
unless it shall object thereto by written notice to the Administrative Agent
within five Domestic Business Days after delivery of notice thereof, and that
any Bank may, without the consent of either Borrower, at any time grant
participating interests in its Commitment or any or all of its Loans 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
and the Administrative Agent shall continue to deal solely and directly with
such Bank in

44

--------------------------------------------------------------------------------

 

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 (except to either Borrower or to any Affected Bank) (each an
“Assignee”) all, or a proportionate part (equivalent to an initial Commitment of
not less than $1,000,000 (unless the Company 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 Administrative Agent
(which shall not be unreasonably withheld or delayed) and, so long as no Event
of Default has occurred and is continuing, the Company (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 $1,000,000 (unless the Company 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

45

--------------------------------------------------------------------------------

 

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 in the amount of $3,500 payable by the
transferor Bank to the Administrative Agent for its own account.
     (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.
     Section 9.08. Confidentiality. Each Agent and each Bank agrees to keep any
information delivered or made available by either 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, (i) subject to
provisions substantially similar to those contained in this Section 9.08, to any
actual or proposed Participant or Assignee and (j) to any direct, indirect,
actual or prospective counterparty (and its advisor) to any swap, derivative or
securitization transaction related to the obligations under this Agreement.

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.

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.

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

Bank to identify such Borrower in accordance with the Act.

     Each Borrower’s credit rating will be determined based upon the rating
assigned to its outstanding senior unsecured long-term debt securities by
Standard & Poor’s, a division of the McGraw-Hill Companies, together with its
successors (“S&P”) and Moody’s Investors Service (“Moody’s”), or, if such a
credit rating is not available for either Borrower, then such Borrower’s credit
rating will be determined based upon its corporate credit rating from S&P or its
issuer rating from Moody’s. Each Borrower will maintain the ratings contemplated
above from at least one of S&P and Moody’s. If the applicable rating is
available from only one of such rating agencies, the applicable pricing will be
based on that rating. 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 will
be the higher of the two; provided that if the rating differential is more than
one notch, the applicable pricing will be based on a rating one notch lower than
the higher of the two.

OPINION OF INTERNAL COUNSEL OF THE BORROWER
[Effective Date]
To the Banks and the Administrative Agent
  Referred to Below
c/o Branch Banking and Trust Company
   as Administrative Agent
200 West 2nd Street, 16th Floor
Winston-Salem, NC 27101
Attn: Loan Syndications
Ladies and Gentlemen:
     I am [title of internal counsel] of Duke Energy Corporation (the “Company”)
and Duke Energy Carolinas, LLC (“Duke Energy Carolinas” and, together with the
Company, the “Borrowers”) and have acted as their counsel in connection with the
Credit Agreement (the “Credit Agreement”), dated as of April 7, 2010, among the
Borrowers, the banks listed on the signature pages thereof, Branch Banking and
Trust Company, as Administrative Agent, and the other Agents party thereto.
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 Company is a Delaware corporation validly existing and in good
standing under the laws of Delaware. Duke Energy Carolinas is a North Carolina
limited liability company validly existing and in good standing under the laws
of North Carolina.
     2. The execution, delivery and performance by each Borrower of the Credit
Agreement and any Notes are within such Borrower’s corporate or limited
liability company powers, as the case may be, have been duly authorized by all

necessary corporate or limited liability company action, as the case may be,
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, by-laws, articles of
organization or limited liability company agreement, as the case may be, of such
Borrower or, to my knowledge, of any agreement, judgment, injunction, order,
decree or other instrument binding upon such Borrower or, to my knowledge,
result in the creation or imposition of any Lien on any asset of such 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 each Borrower.
     4. Except as disclosed in the Company’s annual report on Form 10-K for the
fiscal year ended December 31, 2009, to my knowledge (but without independent
investigation), there is no action, suit or proceeding pending or threatened
against or affecting either 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 such 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 such 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 North Carolina and do not express
any opinion herein concerning any law other than the law of the State of North
Carolina, the federal law of the United States of America and the General
Corporation Law of the State of Delaware.
     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.

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 Branch Banking and Trust Company
   as Administrative Agent
200 West 2nd Street, 16th Floor
Winston-Salem, NC 27101
Attn: Loan Syndications
Ladies and Gentlemen:
     We have acted as counsel to [Duke Energy Corporation., a Delaware
corporation], [Duke Energy Carolinas, LLC, a North Carolina limited liability
company] (the “Borrower”), in connection with the Credit Agreement (the “Credit
Agreement”), dated as of April 7, 2010, among Duke Energy Corporation and Duke
Energy Carolinas, LLC (the “Borrowers”), the banks listed on the signature pages
thereof, Branch Banking and Trust Company, as Administrative Agent, and the
other Agents party thereto. 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

B-2-1

--------------------------------------------------------------------------------

 

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.

B-2-2

--------------------------------------------------------------------------------

 

     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

B-2-3

--------------------------------------------------------------------------------

 

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 2.16 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,

Dear Sirs:
     We have participated in the preparation of the Credit Agreement (the

Company, as Administrative Agent (the “Administrative Agent”), and the other
Agents party thereto, 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.
     In rendering the opinion contained herein, we have assumed, among other
things, that the Credit Agreement and any Notes to be executed (i) are within
each 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

official and (v) do not contravene, or constitute a default under, any provision
of applicable law or regulation or of either Borrower’s certificate of
incorporation or by-laws or any agreement, judgment, injunction, order, decree
or other instrument binding upon either Borrower or result in the creation or
imposition of any Lien on any asset of either Borrower.
     Upon the basis of the foregoing, we are of the opinion that 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, 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.
     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,
