GENERAL TERMS AND CONDITIONS (Cont'd)

25. GAS QUALITY

25.1 General Requirement. Natural gas delivered to Transporter and redelivered to Shipper hereunder shall

at all times conform to the quality provisions set forth in this Section. Transporter shall not be required

to receive gas from Shipper or for Shipper's account that does not conform to the requirements of this

Section. Shipper shall indemnify Transporter and save it harmless from all suits, actions, regulatory

proceedings, damages, costs, losses and expenses (including reasonable attorney fees) arising out of the

failure of said gas to conform to such quality provisions.

25.2 Gas. The gas delivered to Transporter and redelivered to Shipper hereunder 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 Section 25.3(a) herein;

(b) gas generated by vaporization of Liquefied 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.

25.3 Processing.

(a) The gas received and delivered hereunder shall be natural gas as defined in Section 25.2 above;

provided, however, that:

(1) Transporter may extract or permit the extraction of moisture, helium, natural

gasoline, butane, propane, and/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 Shipper's judgment reasonably exercised, would materially affect

the utilization of the gas delivered hereunder, and

(2) 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 or points of delivery.

(b) Processing, as used in this Section 25, shall include processing, treatment, conditioning and

extraction of the gas stream.

(c) If Shipper's gas is transported through a processing plant on Transporter's system and the

Heating Value of the gas at the point it enters Transporter's system is higher than 1130 Btu ("Gas Requiring

Processing"), then the Producer of that gas shall enter into a processing agreement with the owner/operator of

the applicable processing plant on Transporter's system. If requested by Transporter, Producer shall provide

proof to Transporter that it has entered into such a processing agreement. Transporter may decline to receive

Gas Requiring Processing into Transporter's system if Producer has not entered into such a gas processing

agreement.

(d) If Gas Requiring is produced by multiple Producers and commingled before it enters

Transporter's system, then the operator of the meter at the point the comingled Gas Requiring Processing

enters Transporter's system (referred to in this Section as "Meter Operator") shall be responsible for either

entering into a processing agreement covering all of the volumes flowing through the meter or providing to

Transporter or its designee the proper allocation of all quantities and Btu values among all Producers

delivering Gas Requiring Processing into Transporter's system at that point.
