	 	Re:
	 	Revolving Credit Facility






Ladies and Gentlemen:



     BRANCH BANKING AND TRUST COMPANY (the “Lender”) is pleased to make available to
PIEDMONT NATURAL GAS COMPANY, INC., a North Carolina corporation (the “Borrower”), a
revolving credit facility on the terms and subject to the conditions set forth below. Terms not
defined herein have the meanings assigned to them in Exhibit A hereto.




	1.	 	The Facility.






	 	(a)	 	The Commitment. Subject to the terms and conditions set forth herein, the
Lender agrees to make available to the Borrower until the Maturity Date a revolving
credit facility providing for loans (“Loans”) in an aggregate principal amount
not exceeding at any time $25,000,000 (the “Commitment”). Within the foregoing
limit, the Borrower may borrow, repay and reborrow Loans until the Maturity Date.
	 
	 	(b)	 	Borrowings. The Borrower may request that Loans be made by irrevocable notice
to be received by the Lender not later than 11:00 a.m. on the Business Day of the
borrowing. Notices pursuant to this Paragraph 1(b) may be given by telephone
if promptly confirmed in writing.






	 	 	Each Loan shall be in a minimum principal amount of $500,000 or a whole multiple of
$100,000.






	 	(c)	 	Interest. Loans shall bear interest at a rate per annum equal to the Adjusted
LIBOR Rate. Interest hereunder shall be calculated on the basis of a year of 360 days
and actual days elapsed.






	 	 	The Borrower promises to pay interest for all Loans on (i) the first Business Day following
the end of each month; and (ii) the Maturity Date. If the time for any payment is extended
by operation of law or otherwise, interest shall continue to accrue for such extended
period.

(1) After the date any principal amount of any Loan is due and payable (whether on the
Maturity Date, upon acceleration or otherwise), or after any other monetary obligation
hereunder shall have become due and payable (in each case without regard to any applicable
grace periods), and




(2) while any Event of Default exists, the Borrower shall pay, but only to the extent
permitted by law, interest (after as well as before judgment) on such amounts at a rate per
annum equal to the Adjusted LIBOR Rate plus 2.000%. Accrued and unpaid interest on past due
amounts shall be payable on demand.




	 	 	In no case shall interest hereunder exceed the amount that the Lender may charge or collect
under applicable law.






	 	(d)	 	Evidence of Loans. The Loans and all payments thereon shall be evidenced by
the Lender’s loan accounts and records; provided, however, that upon
the request of the Lender, the Loans may be evidenced by a promissory note in the form
of Exhibit B hereto in addition to such loan accounts and records. Such loan
accounts, records and promissory note shall be conclusive absent manifest error of the
amount of the Loans and payments thereon. Any failure to record any Loan or payment
thereon or any error in doing so shall not limit or otherwise affect the obligation of
the Borrower to pay any amount owing with respect to the Loans.
	 
	 	(e)	 	Unused Fee. The Borrower promises to pay a fee equal to 0.25% times the actual
daily amount by which the Commitment exceeds the amount of Loans outstanding, payable
in arrears on the last Business Day of each calendar quarter and on the Maturity Date,
and calculated on the basis of a year of 360 days and actual days elapsed.
	 
	 	(f)	 	Repayment. The Borrower promises to pay all Loans then outstanding on the
Maturity Date.






	 	 	The Borrower shall make all payments required hereunder not later than 2:00 p.m. on the date
of payment in same day funds in Dollars at the office of the Lender as set forth in
Schedule 10.02 to the Incorporated Agreement or such other address as the Lender may
from time to time designate in writing.
	 
	 	 	All payments by the Borrower to the Lender hereunder shall be made to the Lender in full
without set-off or counterclaim and free and clear of and exempt from, and without deduction
or withholding for or on account of, any present or future taxes, levies, imposts, duties or
charges of whatsoever nature imposed by any government or any political subdivision or
taxing authority thereof. The Borrower shall reimburse the Lender for any taxes imposed on
or withheld from such payments (other than taxes imposed on the Lender’s income, and
franchise taxes imposed on the Lender, by the jurisdiction under the laws of which the
Lender is organized or in which its principal office is located or any political subdivision
thereof).

	 	(g)	 	Prepayments. The Borrower may, upon same-day notice, prepay Loans on any
Business Day. Prepayments of Loans must be in a principal amount of $500,000 or a
whole multiple of $100,000, or, if less, the entire principal amount thereof then
outstanding.
	 
	 	(h)	 	Commitment Reductions. The Borrower may, upon five Business Days’ notice,
reduce or cancel the undrawn portion of the Commitment, provided, that the
amount of such reduction is not less than $10,000,000 or a whole multiple of $1,000,000
in excess thereof.






	2.	 	Upfront Fee. The Borrower shall pay to the Lender, for its own account, a fee (the
“Upfront Fee”) in the amount of $25,000.00. Such Upfront Fee shall be for the
Lender’s participation in the revolving credit facility and shall be payable in full upon the
Closing Date.
	 
	3.	 	Conditions Precedent to Loans.

opinions) as the Lender may reasonably request; and
	 
	 	(vi)	 	any fees (including the Upfront Fee) and expenses required to

of the Incorporated Agreement, including for purposes of this Paragraph 4 each

date, except to the extent that such representations and warranties specifically refer to an
earlier date, in which case they shall be true and correct as of such earlier date. The
representations and warranties of the Borrower referred to in the preceding sentence
(including all exhibits, schedules and defined terms referred to therein) are hereby (or, in
the case of each Additional Incorporated Agreement Representation, shall, upon its
effectiveness, be) incorporated herein by reference as if set forth in full herein.
	 
	 	 	All such representations and warranties so incorporated herein by reference shall survive
any termination, cancellation, discharge or replacement of the Incorporated Agreement.
	 
	5.	 	Covenants. So long as principal of and interest on any Loan or any other amount payable
hereunder or under any other Loan Document remains unpaid or unsatisfied and the Commitment
has not been terminated, the Borrower shall comply with all the covenants and agreements
applicable to it contained in Article VI (Affirmative Covenants) and Sections 7.03,
7.04, 7.05, 7.06 and 7.07 (Negative Covenants) of the
Incorporated Agreement, including for purposes of this Paragraph 5 each Additional

	 	(e)	 	Any “Event of Default” specified in Section 8.01 of the Incorporated
Agreement (including for purposes of this Paragraph 6(e) each Additional
Incorporated Agreement Event of Default) occurs and is continuing, without giving

that each such “Event of Default” shall survive any termination, cancellation,

terminated, whereupon the Commitment shall be terminated, and/or declare all sums
outstanding hereunder and under the other Loan Documents, including all interest thereon, to

Maturity Date. The Borrower further promises to pay interest on the unpaid principal amount of the

of, the Agreement, which Agreement, among other things, contains provisions for acceleration of the
maturity of the Loans evidenced hereby upon the happening of certain stated events and also for
prepayments on account of principal of the Loans prior to the maturity thereof upon the terms and
conditions therein specified.



     Unless otherwise defined herein, terms defined in the Agreement are used herein with their
defined meanings therein. This promissory note shall be governed by, and construed in accordance
with, the laws of the State of North Carolina.
