Prior period adjustment time limits should be 6 months from the date of the initial

transportation invoice and 7 months from the date of the initial sales invoice with a

3-month rebuttal period, excluding government required rate changes. The standard

shall not apply in the case of deliberate omission or misrepresentation or mutual

mistake of fact. Parties' other statutory or contractual rights shall not otherwise

be diminished by this standard.

(e) Supporting Data

Seller and Buyer shall each deliver to the other for examination such pertinent

records and charts as shall be necessary to verify the accuracy of any statement,

chart or computation made by either of them under or pursuant to any of the provisions

hereof, of the applicable rate schedule or of the service agreement.

7. PAYMENTS

(a) Payment of Bills for Service under Seller's Sales, Storage and Transportation Rate

Schedules

Except as otherwise hereinafter provided in this Section 7, Buyer shall pay to Seller

by wire transfer of immediately available funds on or before the 10th day of each

month Seller's bill for the Firm Service Charge, Non-Gas Demand Charges, Demand

Charges, Reservation Charges and Storage Capacity Quantity Charges for gas service

rendered during the preceding calendar month and any adjustment of these charges for

the previous month(s) and, on or before the 20th day of each month, Seller's bill for

the remainder of the charges for gas service rendered during the preceding calendar

month and any adjustment of these charges for the previous month(s); provided,

however, Buyer may make payment by check (in accordance with the aforementioned

payment due dates) rather than by wire transfer if Seller's bill(s) for the preceding

calendar month does not exceed an aggregate of $100,000.00; provided further, however,

Seller may agree, on a non-discriminatory basis, to accept payment from a Buyer by

check rather than wire transfer if Seller's bill(s) for the preceding calendar month

exceeds an aggregate of $100.000.

If the payment date is a Saturday, Sunday or holiday, then payment is due the

following business day.

Party making payment should submit supporting documentation; party receiving payment

should apply payment per supporting documentation provided by the paying party; and if

payment differs from invoiced amount, remittance detail should 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 due date. The

Statement of Account should report outstanding balances by invoice.
