GENERAL TERMS AND CONDITIONS

(continued)

6. BILLING AND PAYMENTS

6.1 Billing: On or before the tenth (10th) day of each month,

Transporter shall render to each Shipper a bill for the actual

service rendered during the immediately preceding month ("billing

month") if actual data is available. All statements should be

standardized to the same level of detail. The specific minimum

level of detail on invoice, remittance and statement of an account

should be guided by the development of data elements. If actual

data is not available, billing will be on an estimated basis and

such estimate will be corrected to actual tools on the billing

immediately following receipt by Transporter of such actual data.

Bills will utilize the descriptions and charge codes set forth in

the NAESB Standards. Transportation bills shall specify all rate

components, and shall separately state the net billing rate and any

discount, if applicable, and any prior period adjustments. Prior

period adjustments are reported by production date, but they do not

have to be invoiced separately by production month - nor is each

production month a separate paper invoice page. Required invoice

backup data should accompany or precede this invoice. Regarding

inadequate detail, supporting documentation should be provided upon

request, with timing of supporting documentation to follow the

timing of the flowing gas transactions.

6.2 Payment: Within ten (10) calendar days after the date of receipt of

billing invoice, or the next business day in the event the tenth

(10th) day is a weekend or bank holiday, Shipper shall provide any

supporting documentation, including invoice number(s), and shall pay

Transporter by check, or by wire transfer of federal funds, the

amount of the bill rendered by Transporter for the billing month in

accordance with Section 6.1. For purposes of this Section, the date

of receipt of billing invoice is deemed to be three (3) days after

the postmark date. Any payment shall be considered to have been

made on the date such payment is transferred by Shipper to the

address designated by Transporter. If presentation of a bill by

Transporter is delayed after the due date, then the time for payment

shall be extended correspondingly unless Shipper is responsible for

such delay. If Shipper has notified Transporter in writing of an

error in invoice during the period for which a genuine dispute

exists as to the alleged error, Shipper shall pay the portion of the

invoiced amount which is not in dispute and shall provide

documentation identifying the basis for the dispute.
