In accordance with NAESB Standard 2.3.14, Version 1.8, measurement

data corrections should be processed within 6 months of the

production month with a 3-month rebuttal period. However, it is

recognized that this latter 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 be

diminished by this standard.




7.1 Billing under all Rate Schedules: On or before the ninth (9th)

business day of each month, GTN shall render a bill to each Shipper

under all applicable Rate Schedules for the service(s) rendered

during the preceding month, which is in accordance with NAESB

Standard 3.3.14, Version 1.8, which provides that 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.


7.2 Third Party Charges. Shipper shall be responsible for delivering

all gas to, and accepting redelivery of all Gas from, Transporter's

system, and shall be free to contract with third party(ies)

upstream or downstream of Transporter's system to achieve such

result. If Shipper requests, and Transporter agrees, Transporter

will contract with third party(ies) for the benefit of Shipper and

Shipper shall pay Transporter an amount equal to the charges

Transporter is obligated to pay such third party(ies), which

charges may include, but are not limited to, reservation and/or

usage charges and surcharges, fuel charges, compression fees,

balancing or storage fees, measurement fees, processing fees,

and/or facility charges. Such charges shall be set forth as

separate items on billings rendered to Shipper.


7.3 Invoice Consolidation Fee. GTN may, upon mutual agreement with

Shipper, enter into agency agreements on third-party pipelines that

will allow GTN to receive third-party pipeline invoices billed to

Shipper and consolidate such invoices with GTN's monthly invoice to

Shipper. An invoice consolidation fee shall be negotiated between

GTN and Shipper for such service. GTN will provide this service on

a non-discriminatory basis.
