II.  Transportation Credit
  1. Seller shall provide to Buyer, as a credit against the
Contract Rates, a Transportation Credit ("TC") for the sale
from the Buyer to Seller of projected available annual
portfolio entitlements.
  2. The Transportation Credit shall be calculated from time
to time to reflect changes in projected available annual
entitlements, based on the following formula:

  TC = Base TC x Projected Available Annual Entitlements
                   Base Available Annual Entitlements

  Where:  a.   Base TC = $1,864,290
          b.   Base Available Annual Entitlements =
35,843,831 Dth

               entitlements historically supplied by longhaul pipeline
               transportation entitlements reserved by Buyer.
            (ii) Normal Demand is the projected normal weather quantity
               of entitlements historically supplied by firm longhaul
               pipeline deliveries for firm customers.

  3.  The TC shall be divided among months based upon the
projected available monthly entitlements.
Amendment
     Seller and Buyer agree that this Appendix C may be
amended from time to time by mutual agreement of the
Parties, which ultimately will be memorialized in a revised
Appendix C.

               Appendix E- Commodity Purchases

     This Appendix E addresses the gas supply and other
variable costs applicable to Nominated Daily Quantities and
Balancing Quantities as identified below.
For Monthly Baseload Purchases:
     Buyer shall pay to Seller each Contract Month an amount
determined by multiplying the monthly baseload quantities of
Gas scheduled for Buyer's purchase under this Agreement
during the Contract Month, by a price per MMBtu determined
using the first monthly index from Inside FERC's GAS MARKET
REPORT, in the table "PRICES OF SPOT GAS DELIVERED TO
INTERSTATE PIPELINES" for the applicable zone, specified
below, for the applicable month, plus all other applicable
variable costs as identified below shall apply.
For Daily Swing Purchases:
     Buyer shall pay to Seller each Contract Month an amount
determined by summing all applicable "Daily Amounts" for the
Contract Month.  A "Daily Amount" shall be calculated for
each day during the Contract Month for which daily swing
quantities of Gas have been confirmed for purchase.  The
"Daily Amounts" shall be determined by multiplying (a) the
confirmed swing quantities of gas scheduled for the
particular day of the Contract Month, by (b) a price per
MMBtu determined using the Daily Midpoint Price reported in
Gas Daily, in the table "DAILY PRICE SURVEY", for the
applicable zone, specified below, for purchases for the
applicable day.   As to any day for which Gas Daily for any
reason (e.g. holidays and weekends) does not publish the
above referenced prices, the applicable prices shall be that
utilized for the last prior day such is published.   In
addition all other applicable variable costs as identified
below shall apply.
For Other Purchases:
     For any purchases not covered by a specified pricing
method, or for fixed price quantities, pricing shall be as
negotiated and mutually agreed to in writing by the Parties.
For Summer Storage Refill:
     For summer refill of leased storage, Buyer shall pay to
Seller an amount based on averaging the seven summer monthly
indices for the applicable supply area, and based upon
presuming storage refill quantities to be equally split
between the summer months.  For summer refill of company
storage, the parties will agree on the extent to which an
index average method will be used, after consideration of
the operational scheduling needs of company storage.  In
addition, all other applicable variable costs as identified
below shall apply.
               Appendix E- Commodity Purchases

For Storage Withdrawals:
     For quantities of storage withdrawals for which Buyer
has previously paid for commodity, applicable storage
withdrawal variable costs as identified below shall apply.
