12.1 Billing. On or before the ninth (9th) Business Day of each Month,

Transporter shall Render or furnish via email or other methods

described in Section 12 to Shipper an invoice for the total

payment due hereunder for Transportation Service during the

preceding Month. Invoices shall be deemed Rendered when

Transporter posts notification on its EBB that invoices are

final. Shipper may also access their invoice on the Xpress

system or may request to have invoices Rendered via U.S. Mail.

If the Shipper elects to have invoices Rendered via U.S. Mail,

then Shipper's invoice shall be deemed Rendered when Transporter

places such invoice in the U.S. Mail service with sufficient

postage for delivery to the person and address designated

pursuant to the applicable Service Agreement.


(a) A Shipper may request a complimentary e-mail notification

of posting of the invoice on the EBB, provided that it is

the Shipper's responsibility to maintain current e-mail

information with Transporter to ensure delivery.


(b) A Shipper may elect to change its invoice delivery

mechanism by notifying Transporter before the end of the

month to be effective for the next billing cycle.


(c) Transporter shall accompany such invoice with a schedule

showing the quantities of Gas (in Dth) received and

Delivered and constituting a thermal balance (including

FL&U, Gas vented, and any imbalance under Section 10

hereof). Should Transporter be unable to furnish a

statement of actual quantities by the ninth (9th) Business

Day of any Month, Transporter may furnish an estimated

statement and make appropriate adjustments in the

statement Rendered for the next succeeding Month.


(d) It is Transporter's intent to comply with the standards

published by the North American Energy Standards Board

("NAESB"). The NAESB Standards related to this Billing and

Payment section are incorporated by reference in Section

1.31, except for the following NAESB Standards

incorporated verbatim:

3.3.14 The imbalance statement should be rendered prior to

or with the invoice, and the transportation invoice

should be prepared on or before the 9th Business

Day after the end of the production Month. Rendered

is defined as postmarked, time-stamped, and

delivered to the designated site.
