GENERAL TERMS AND CONDITIONS

9.2 Each month, WTG Hugoton shall submit to Shipper a statement and billing

for the reservation and usage charges associated with the services rendered

during the preceding month. If actual measurement data is not available

within five (5) business days after the end of the production month, then

billing will be based on the best available measurement data and corrected as

a prior period adjustment in a subsequent month. Quantities at points where

OBAs exist should be invoiced based on scheduled quantities. The statements

and billings shall be rendered on or before the 9th Business Day after the end

of the production month. The term "rendered" shall mean postmarked,

time-stamped or delivered to the designated site. Shipper shall pay to WTG

Hugoton the amount shown as due by such billing within ten (10) days of the

issuance of such billings in immediately available U.S. funds at a depository

designated by WTG Hugoton. Checks received in WTG Hugoton's designated

depository at least two (2) business days before the invoice due date will be

considered to be immediately available funds on the due date. When the due

date falls on a day that the designated depository is not open in the normal

course of business to receive the Shipper's payment, the Shipper shall cause

such payment to be made on or before the first business day on which the

designated depository is open after such due date. Shipper shall submit

supporting documentation with any payment. Shipper shall identify invoice

number(s) on all payments.

9.3 The party making the payment shall submit supporting documentation; the

party receiving the payment shall apply the payment per the supporting

documentation provided by the paying party; and if the payment differs from

the invoiced amount, remittance detail shall 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 date.
