GENERAL TERMS AND CONDITIONS (continued)

2. QUALITY

2.1 Gas: The gas received by Transporter under this Tariff shall be a

combustible gas consisting wholly of, or a mixture of:

(a) Natural gas of the quality and composition produced in its

natural state except as provided for in Sub-section 2.2(a)

herein;

(b) Gas generated by vaporization of Liquified Natural Gas

("LNG"); or

(c) Manufactured, reformed, or mixed gas consisting essentially

of hydrocarbons of the quality and character produced by

nature in the petroleum, oil, and gas fields with physical

properties such that when the gases are commingled, they

become indistinguishable with respect to the physical

properties of the mixture.

2.2 Processing: The gas delivered hereunder shall be natural gas;

provided however, that:

(a) Transporter may extract or permit the extraction of

moisture, helium, natural gasoline, butane, propane, or

other hydrocarbons (except methane) from said natural gas,

or may return thereto any substance extracted from it.

Transporter, in order to conserve and utilize other

available gases, may blend such gases with said natural gas.

Provided, however, that such blending shall not extend to a

degree which, in Transporter's judgment reasonably

exercised, would materially affect the utilization of the

gas delivered hereunder.

(b) Transporter may subject or permit the subjection of said

natural gas to compression, cooling, cleaning or other

processes to such an extent as may be required in its

transmission from the source thereof to the Point(s) of

Delivery.
