14. BILLING AND PAYMENT

14.1 Billing:

The transportation invoice shall be prepared on or before the 9th

business day after the end of the production month. Transporter

shall render to Shipper a statement of the volumes and the Btu

content of the gas received for the account of Shipper for

transportation, the volumes and the Btu content of the gas

delivered to or for the account of Shipper, and the amount of

lost-and-unaccounted-for gas allocated to Shipper in the preceding

month. Imbalance statements shall be generated at the same time

or prior to the generation of the transportation invoice. The

imbalance statement shall be rendered prior to or with the

invoice. Rendered is defined as postmarked, time-stamped, and

delivered to the designated site. Transporter may furnish

separate statements to Shipper that include an account of any

credits and/or penalty charges accrued by Shipper. Invoices shall

be based on actual (if available) or best available data.

Quantities at a point where an OBA exists should be invoiced based

on scheduled quantities. Unless otherwise agreed, transportation

invoices shall state the net billing rate rather than the

discounted Maximum Rate and the discount amount. Billing units

will be stated in Dekatherms.

14.2 Payment:

Billing statements shall be deemed to be received by each Shipper

within three (3) business days after the date they are mailed by

Transporter. Shipper shall make payments to Transporter for the

services performed or charges levied hereunder during the

preceding month by electronic bank transfer (i.e. wire transfer,

ACH transfer or other mutually acceptable transfer method) or by

check, at such address as Transporter may hereafter designate, on

or before the later of the twenty-fifth (25th) day of the month or

ten (10) days after Shipper's receipt of the billing statement.

Any amount due Shipper from Transporter shall be paid in a like

manner. All payments made by Shipper shall include Transporter's

invoice number(s) and supporting documentation for purposes of

matching the payment to the invoice.

Transporter should apply payment per supporting documentation

provided by the Shipper. 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.
