                                      GENERAL TERMS AND CONDITIONS

                   failure on the part of either shall be due to force majeure as
                   defined in Section 10 "FORCE MAJEURE" in these GENERAL TERMS AND
                   CONDITIONS, provided, such party shall promptly and diligently take
                   such action as may be necessary and practicable under the then
                   existing circumstances to remove the cause of failure and resume the
                   delivery or receipt of gas, as the case may be, provided, however,
                   that neither Northern nor the Shipper shall be relieved of liability
                   to the other for any damages or expense caused or contributed to by
                   its own negligence when such negligence on its part shall be the
                   proximate cause of its failure to deliver or receive gas, as the case
                   may be.  If failure to deliver or receive gas is caused by negligence
                   on the part of Northern, then Northern shall offer to credit
                   reservation charges to the Shipper during such failure.

               8.  BILLING AND PAYMENT
                   -------------------

                   For purposes of this Section 8, all references to "day" shall be
                   deemed to mean "billing day" and all references to "month" shall be
                   deemed to mean "billing month".

                   Each month, Northern shall submit to Shipper a statement and billing
                   for the demand/reservation/capacity charge portion of actual services
                   rendered during the preceding month.  Additionally, Northern shall
                   submit to Shipper, or its Designee, a separate statement and billing
                   for the commodity portion of actual services rendered during the
                   preceding month, if available.  If actual measurement data is not available
                   within five (5) business days after the end of the production month, then
                   billing will be based on the best available measurement data and corrected
                   as a prior period adjustment in a subsequent month.  Quantities at points
                   where OBAs exist should be invoiced based on scheduled quantities.  The
                   statements and billings shall be rendered on or before the 9th Business
                   Day after the end of the production month.  The term "rendered" shall
                   mean postmarked, time-stamped or delivered to the designated site.  Shipper
                   shall pay to Northern the amount shown as due by such billing within ten
                   (10) days of the issuance of such billings in immediately available U.S.
                   funds at a depository designated by Northern.  When paying the original
                   invoice, the Shipper shall have the right to adjust its payment relative to
                   imbalance cash in/out amounts to reflect its imbalance resolution elections
                   pursuant to Section 32 of the GENERAL TERMS AND CONDITIONS of this tariff.
                   Checks received in Northern's designated depository at least two (2)
                   business days before the invoice due date will be considered to be
                   immediately available funds on the due date.  When the due date falls on a
                   day that the designated depository is not open in the normal course of
                   business to receive the Shipper's payment, the Shipper shall cause such
                   payment to be made on or before the first business day on which the
                   designated depository is open after such due date.  Shipper shall submit
                   supporting documentation with any payment.  Shipper shall identify invoice
                   number(s) on all payments.  The party making the payment shall submit
                   supporting documentation; the party receiving the payment shall apply the
                   payment per the supporting documentation provided by the paying party; and
                   if the payment differs from the invoiced amount, remittance detail shall be
                   provided with the payment except when payment is made by electronic funds
                   transfer (EFT), in which case, the remittance detail is due within two
                   Business Days of the payment date.

                   Each month, Northern shall also provide Shipper with a detailed monthly
                   Statement of Account.  Such Statement of Account shall indicate any
                   outstanding amounts billed during the current month.  Upon request, Northern
                   will provide a statement showing the outstanding cumulative account
                   activity.
