Re:		Amended and Restated Revolving Credit Facility

Ladies and Gentlemen:

     This Amended and Restated Revolving Credit Facility (this “Agreement”) is entered into between BANK OF AMERICA, N.A. (the “Lender”) and PIEDMONT NATURAL GAS COMPANY, INC., a North Carolina corporation (the “Borrower”). Terms not defined herein have the meanings assigned to them in Exhibit A hereto.

     The Borrower and the Lender have entered into that certain Revolving Credit Facility dated as of October 27, 2008 (as in effect on the date hereof, the “Existing Credit Facility”).

     The Borrower and the Lender desire to amend and restate the Existing Credit Facility to, among other things, extend the maturity date of the revolving credit facility and make certain other changes as set forth herein, all subject to the terms and conditions set forth in this Agreement.

1A. Amendment and Restatement. In order to facilitate the amendment and restatement of the Existing Credit Facility and otherwise to effectuate the desires of the Borrower and the Lender:

	(a)		The Borrower and the Lender hereby agree that, (i) this Agreement constitutes an amendment and restatement of the Existing Credit Facility, and (ii) on the Closing Date, the terms and provisions of the Existing Credit Facility shall be and hereby are amended and restated in their entirety by the terms, conditions and provisions of this Agreement, and the terms and provisions of the Existing Credit Facility, except as otherwise expressly provided herein, shall be superseded by this Agreement.
	(b)		Notwithstanding this amendment and restatement of the Existing Credit Facility and any amendment and restatement of any related “Loan Documents” (as such term is defined in the Existing Credit Facility and referred to herein as the “Existing Loan Documents”), (i) all obligations outstanding under the Existing Credit Facility and other Existing Loan Documents (the “Existing Obligations”) shall, except to the extent repaid on the Closing Date, continue as obligations hereunder, and (ii) neither the execution and delivery of this Agreement or any other Loan Documents nor the consummation of any other transactions contemplated hereunder or thereunder is intended to constitute a novation of the Existing Credit Facility or of any of the other Existing Loan Documents or any obligations thereunder. Upon the effectiveness of this Agreement, all Loans owing by the Borrower

and outstanding under the Existing Credit Facility shall be repaid with an advance of Loans hereunder. Together with such repayment, the Borrower shall pay (on the Closing Date) all accrued interest and fees with respect to the Existing Obligations.

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 $50,000,000 (the “Commitment”). Within the foregoing limit, the Borrower may borrow, repay and reborrow Loans until the Maturity Date.
	(b)		Borrowings, Conversions, Continuations. The Borrower may request that Loans be (i) made as or converted to Base Rate Loans by irrevocable notice to be received by the Lender not later than 11:00 a.m. on the Business Day of the borrowing or conversion, or (ii) made as or converted to LIBOR Floating Rate Loans by irrevocable notice to be received by the Lender not later than 11:00 a.m. on the Business Day of the borrowing or conversion. 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. At the option of the Borrower, Loans shall bear interest at a rate per annum equal to (i) the LIBOR Daily Floating Rate plus the Applicable Rate, or (ii) the Base Rate plus the Applicable Rate. Interest on Base Rate Loans when the Base Rate is determined by the Lender’s “prime rate” shall be calculated on the basis of a year of 365 or 366 days and actual days elapsed. All other 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 Base 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

Piedmont Natural Gas
December 1, 2008
Page 3

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 0.250% 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 Termination or Reductions. The Borrower may, upon same-day notice, terminate the Commitment or from time to time permanently reduce the Commitment, provided, that (i) any such notice shall be received by the Lender no later than 11:00 a.m. on the date of such termination or reduction; (ii) any such partial reduction shall not be less than $10,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) the Borrower shall not terminate or reduce the Commitment if, after giving effect thereto and any concurrent prepayments hereunder, the outstanding amount of Loans would exceed the Commitment. All fees accrued until the effective date of any termination of the Commitment shall be paid on the effective date of such termination.

2.

Upfront Fee. Subject to the final sentence of this Paragraph 2, the Borrower shall pay to the Lender, for its own account, a fee (each an “Upfront Fee”) in the amounts and on the dates set forth below. Each such Upfront Fee shall be for the Lender’s Commitment under the revolving credit facility and shall be payable in full upon the date opposite such fee:

     The loan account records maintained by the Lender shall at all times be conclusive evidence, absent manifest error, as to the amount of the Loans and payments thereon; provided, however, that 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.

     This promissory note is the promissory note referred to in, and is entitled to the benefits 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.
