GENERAL TERMS AND CONDITIONS

13. QUALITY

Trunkline shall not be obligated to accept Gas for Transportation which

does not meet these quality provisions:

13.1 Gas received shall be merchantable Natural Gas; shall be free of

water and hydrocarbons in liquid form; shall contain not more

than 7 pounds of water vapor per Mmcf unless otherwise agreed to

in advance by Trunkline, 1.0 grain of hydrogen sulphide and twenty

(20) grains of total sulphur per one hundred (100) cubic feet, 2%

of carbon dioxide and 3% of nitrogen (by volume), and fifty (50)

parts per million of oxygen; shall not contain any active bacteria

or bacterial agent, including but not limited to sulphate reducing

bacteria and acid producing bacteria; shall not contain any

hazardous or toxic substances; and shall not exceed one hundred

twenty degrees (120ø) Fahrenheit in temperature.

13.2 Shipper or Shipper's designee will have the right to process Gas

for the removal of liquids and liquefiable hydrocarbons, except in

case of emergency or if the Gas fails to meet quality

specifications, by electing to exercise such right in writing at

the time the Transportation Service Agreement is executed and

thereafter prior to each January 1 for the next calendar year.

For any period for which the processing election is exercised,

Shipper or Shipper's designee shall be obligated to process all

Quantities of Gas transported under the Transportation Service

Agreement during such period from designated Points of Receipt.

The Quantity of Gas delivered hereunder at the Points of Delivery

shall be Thermally Equivalent to the Quantity of Gas received at

the Points of Receipt less Fuel Reimbursement and the reduction

due to processing. Shipper may satisfy the foregoing requirements

by having the gas which it ships dehydrated so that it conforms to

the quality specifications, so long as such dehydration is

performed onshore prior to the first Trunkline compression

facility. As used throughout this Section 13, the term

"processing" shall be interpreted to include "dehydration."
