GENERAL TERMS AND CONDITIONS

(Continued)

(2) Oklahoma Spot Price Index. The spot price index for Southwest Receipts

shall be the Oklahoma Spot Price Index and will be determined for a week

by use of the published weekly spot prices contained in the following two

publications: (i) Energy Intelligence's Natural Gas Week prices for

deliveries to Transporter of 5,000 MMBtu or more, and (ii) Natural Gas

Intelligence's Weekly Gas Price Index for deliveries to Transporter. The

Oklahoma Spot Price Index for Deficient Quantities will be the highest of

the simple weekly averages of the "ANR spot" prices in the two

publications. The Oklahoma Spot Price Index for Excess Quantities will be

the lowest of the simple weekly averages of the "ANR spot" prices in the

two publications.

(3) Price Reporting and Material Changes. The published spot prices used in

determining the Louisiana Spot Price Index and the Oklahoma Spot Price

Index shall be prices for short term contracts, preferably thirty to

thirty-one Day contracts, on a delivered-to-interstate-pipeline basis.

The published spot prices used shall be the Index prices (volume weighted

average prices), or, if such a volume weighted average price is not

available, an average of the high and low prices reported. If there is a

material change by any of the publications to be used in determining the

Louisiana Spot Price Index or the Oklahoma Spot Price Index in the

definition of how prices are reported for deliveries to Transporter, then

the prices for such deliveries in such publication will no longer be used

in calculating the Index Price.

(4) Cessation of Publications. To the extent the reported prices referenced

above are not published for the Month required, Transporter shall determine

the Louisiana Spot Price Index or Oklahoma Spot Price Index using another

similar publication selected by Transporter in its reasonable judgment that

is broadly published and widely accepted within the gas industry as a

reliable source for the quotation of gas prices.
