GENERAL TERMS AND CONDITIONS

3.7 The unit of volume "at 1,000 Btu per cubic foot" or "as adjusted to

1,000 Btu per cubic foot" shall mean one cubic foot of gas as defined above

and having an average total heating value of one thousand (1,000) British

Thermal Units. Such units of volume shall be determined by multiplying the

number of cubic feet of gas delivered during any billing day by the factor

arrived at by dividing the average total heating value per cubic foot

delivered on the previous day by 1,000 unless otherwise agreed to by WTG

Hugoton.

3.8 Supercompressibility. Determination of supercompressibility of natural

gas shall be calculated from chromatographic analysis of gas samples taken at

representative points as determined by WTG Hugoton.

3.9 Gas Sampling and Analysis. Gas samples may be obtained and analyzed by

one of the following methods:

(a) Portable Chromatograph. Chromatographic analysis of a spot sample

of gas taken at a representative location and analyzed on site by means of a

portable gas chromatograph.

(b) Spot Sample. Spot sample of gas taken at a representative location

using a sample bottle and analyzed using a gas chromatograph at a location

remote from the sampling location.

(c) Continuous Sample. Sampling continuously into a sample bottle for

a period of time at a representative location and then analyzing the sample

using a gas chromatograph.

(d) On-Site Gas Chromatograph. On-site chromatograph sampling directly

from a representative source and analyzing continuously.

(e) System Gas Chromatograph. Gas chromatograph sampling directly from

a representative source and analyzing continuously. The results are then

applied to all other locations on the system that are representative of the

sample source.

Spot Sampling Frequency. Mutually agreed upon frequency (monthly, quarterly,

etc.)
