                  by any Replacement Customer that has purchased capacity
                  released by the Releasing Customer.
   
                  Seller shall credit the invoice of Releasing Customer
                  each Month for the Deliverability and Capacity charges
                  and volumetric rates invoiced, by Seller to Replacement
                  Customer provided, however, that such credit:
   
                  (a)   shall not include any charges billed to the
                        Replacement Customer under Section 5 of this Rate
                        Schedule or Rate Schedule IS, and
   
                  (b)   shall be reduced by the amount of any marketing
                        fee Seller is entitled to collect pursuant to
                        Section 7.4, below.
   
                  If a Replacement Customer fails to pay all or any part
                  of its Deliverability and Capacity charges which have
                  been credited to Releasing Customer within fifteen (15)
                  Days of the due date, such unpaid amount, with
                  applicable interest accruing from the date Replacement
                  Customer's payment was due, will be charged to the
                  Releasing Customer's next monthly bill and will be due
                  and payable by Releasing Customer, unless Replacement
                  Customer in good faith shall dispute the billed charges
                  in accordance with the provisions set forth in Section
                  8.2 of the General Terms and Conditions of this Tariff.
                  If such failure to pay continues for thirty (30) Days
                  after payment is due, and the Replacement Customer has
                  not disputed billings in accordance with Section 8.2 of
                  the General Terms and Conditions of this Tariff, then
                  Seller may, in addition to any other remedies it may
                  have hereunder, terminate its Agreement with the
                  Replacement Customer, and the Replacement Customer shall
                  be deemed to have consented to abandonment of service
                  under the Agreement.  If the Agreement with the
                  Replacement Customer is so terminated and service
                  abandoned, the capacity will revert to the Releasing
                  Customer, and will be governed by the terms and
                  conditions of its existing Agreement with Seller.  If
                  Releasing Customer pays delinquent amounts owed by
                  Replacement Customer and Seller subsequently receives
                  payment from Replacement Customer of some or all of such
                  amounts, Seller will credit the amounts received from
                  the Replacement Customer in Seller's next monthly bill
                  to the Releasing Customer.
