United Gas Pipe Line Company

Post Office Box 1407

Shreveport, Louisiana

Gentlemen:

Our prior discussions have indicated that it would be mutually

beneficial to United Gas Pipe Line Company (United) and Humble Gas

Transmission Company (Humble Gas) if natural gas pipelines of the respective

companies, at certain points of intersection in the State of Louisiana, were

interconnected in such a way that natural gas could be exchanged as between

United and Humble Gas, through mutual dispatching arrangements, under the

terms and conditions hereinafter provided.

Deliveries of natural gas by either United or Humble Gas to the other

can be effected by the metering and interconnecting facilities installed or

to be installed at the following delivery points:

A. At the existing point of interconnection in the vicinity of

Winnsboro, Franklin Parish, Louisiana, where United's

Rayville-Winnsboro pipeline intersects Humble Gas' Fowler-Baton

Rouge pipeline.

B. At the proposed point of interconnection in the vicinity of Baton

Rouge, East Baton Rouge Parish, Louisiana (United's Scotland

Compressor Station Site).

While neither United nor Humble Gas desire to make regular exchange

deliveries of natural gas to the other at either of the points specified

herein, each foresees that it may be able, under certain
