FORM OF TRANSPORTATION SERVICE AGREEMENT

APPLICABLE TO RATE SCHEDULE FT-1 (Continued)

13. Contract Path and Allocation Between Point(s) of Receipt and

Delivery. The contract path and, where deliveries are made at more than

one point, the allocation of MDRQ to be tendered at each point of receipt

among the various delivery point(s) shall be as specified in Exhibit "A"

hereto.

14. Gas Processing. Transporter has the right under its FERC Gas

Tariff to accept gas for transportation that does not meet the applicable

quality specifications (contained in Section 4 of the General Terms and

Conditions of Transporter's FERC Gas Tariff) and make such changes as are

necessary to cause the gas to conform to such specifications. Shipper

represents that it has the full right and authority to allow the gas being

transported to be processed at a gas processing plant and to give the

processor title to all liquids and liquefiable hydrocarbons that are

removed. Shipper hereby authorizes and gives Transporter full right to

receive and tender the gas to a processing plant for processing; and

Shipper gives to the processor title to the liquids and liquefiable

hydrocarbons which are recovered by the processor as a result of its

operations. Shipper shall have no claim to the proceeds from the sale or

use of liquids and liquefiable hydrocarbons recovered. To the extent

possible, however, the processor will replace corresponding Btu's that have

been removed from the gas, such that the total dekatherms of gas received

into the plant from Transporter for processing will remain unchanged from

the total dekatherms of gas redelivered to Transporter after processing.

Shipper agrees to defend, indemnify, and hold harmless Transporter for all

claims, causes of actions, lawsuits, or judgments which arise from or are

attributable to gas processing and the removal of and subsequent disposal

of, liquids and liquefiable hydrocarbons from Shipper's gas. Upon

reasonable notice to Transporter, Shipper shall have the right to make

alternative arrangements for the processing of the gas.

15. This section to be utilized when necessary to specify other

operating provisions.

16. Adjustments to General Terms and Conditions. Certain of the

General Terms and Conditions are to be adjusted for purposes of this

Service Agreement, as specified below:
