GENERAL TERMS AND CONDITIONS

26. BILLING QUANTITY

26.1 Single Shipper. The Billing Quantity ("BQ") shall be the volumes

actually delivered for a Shipper. For monthly billing purposes, the

determination of the BQ for a Shipper transporting gas under more than one

Rate Schedule shall be in the following order (Default Order) unless agreed to

otherwise by WTG Hugoton and the Shipper prior to the beginning of such month.

(a) volumes, including overrun volumes, scheduled for delivery under

Rate Schedule IT, if any;

(b) volumes delivered under Rate Schedule FT in the following order:

(i) scheduled overrun volumes, if any, and (ii) up to the MDQ's of the FT

services.

26.2 Multiple Shippers. For billing purposes, to the extent WTG Hugoton is

transporting gas to a Point(s) of Delivery for more than one (1) Shipper, the

Shipper shall cause the party receiving the gas for Shipper's account at such

Point(s) of Delivery ("Receiving Party") to advise WTG Hugoton of the priority

between Shippers in which said Receiving Party will receive the other

Shippers' scheduled gas. If WTG Hugoton has not been advised of a priority,

the Default Order in Section 26.1 above shall apply. Provided however, if the

Receiving Party is also a FT Shipper, then, for billing purposes, gas being

transported and delivered at the subject Point(s) of Delivery for the

Receiving Party Shipper's FT Agreement shall be deemed to be the last

transportation volumes scheduled through the meter (last-through-the-meter

methodology) preceded by any other agreements in the Default Order unless

agreed to otherwise by WTG Hugoton and the Receiving Party prior to the

beginning of the month, or unless the Receiving Party has chosen to provide

the measured volumes as stated below in Section 26.4.
