Optional Redemption:

We may, at our option, redeem the Notes, in whole at any time, or in part from
time to time, prior to the maturity date, at a redemption price equal to the
greater of:

o        100% of the principal amount of the Notes to be redeemed and

o        as determined by an Independent Investment Banker, the sum of the
         present values of the remaining scheduled payments of principal on the
         Notes to be redeemed and interest thereon (not including any portion of
         payments of interest accrued as of the date fixed for redemption),
         discounted to the date fixed for redemption on a semi-annual basis
         (assuming a 360-day year consisting of twelve 30-day months) at the
         Treasury Rate (as defined below), plus 25 basis points.

plus in either case interest accrued and unpaid on the principal amount of the
Notes to be redeemed to the date fixed for redemption. We will mail notice of
any redemption at least 30 days before the date fixed for redemption to each
holder of the Notes to be redeemed.

"Treasury Rate" means, with respect to any date fixed for redemption, the rate
per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such date.

"Comparable Treasury Issue" means the United States Treasury security selected
by an Independent Investment Banker as having a maturity comparable to the
remaining term of the Notes to be redeemed that would be used, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of the Notes to be redeemed.

"Comparable   Treasury  Price"  means,  with  respect  to  any  date  fixed  for
redemption,

         (1) the average of the bid and asked prices for the Comparable Treasury
         Issue (expressed in each case as a percentage of its principal amount)
         on the third business day preceding such date, as set forth in the
         daily statistical release (or any successor release) published by the
         Federal Reserve Bank of New York and designated "Composite 3:30 p.m.
         Quotations for U.S. Government Securities" or

         (2) if such release (or any successor release) is not published or does
         not contain such prices on such business day, (a) the average of the
         Reference Treasury Dealer Quotations for such date, after excluding the
         highest and lowest such Reference Treasury Dealer Quotations for such
         date, or (b) if the trustee obtains fewer than four such Reference
         Treasury Dealer Quotations, the average of all the quotations received.

"Independent Investment Banker" means any one of the Reference Treasury Dealers
that we may appoint.

"Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer and any date fixed for redemption, the average, as determined by
the trustee, of the bid and asked


                                       2



prices for the Comparable Treasury Issue (expressed in each case as a percentage
of its  principal  amount)  quoted in writing to the  trustee by such  Reference
Treasury  Dealer at 5:00 p.m.  New York  City  time on the  third  business  day
preceding the date fixed for redemption.

"Reference Treasury Dealer" means (1) Banc of America Securities LLC, J.P.
Morgan Securities Inc. and their respective successors, unless any of them
ceases to be a primary U.S. Government securities dealer in New York City (a
"Primary Treasury Dealer"), in which case we will substitute another Primary
Treasury Dealer and (2) any other Primary Treasury Dealers that we may select.

the Notes. Any such securities dealers may resell any Notes purchased from the
purchasers to certain other brokers or dealers at a discount from the initial

$80,000,000 7.38% First Mortgage Bonds that mature on December 1, 2007 and to
repay a portion of our short-term debt. If we do not use the proceeds
immediately, we may temporarily invest them in short-term investments.
