SCOPE OF THE AGREEMENT

Enbridge Pipelines (Midla), Inc. (formerly known as Mid Louisiana) has

contracted to purchase from Molal the portion of the gas produced from Block

140 attributable, to Mobil's interest in said block. Enbridge Pipelines

(Midla), Inc. (formerly known as Mid Louisiana) has assigned a 40% interest in

the Block 140 gas to Southern. This gas will be gathered and delivered by the

producer in Plaquemines Parish, Louisiana. Since Enbridge Pipelines (Midla),

Inc. (formerly known as Mid Louisiana)'s existing pipeline system does not

extend into Plaquemines Parish, Southern hereby agrees to exchange Enbridge

Pipelines (Midla), Inc.'S (formerly known as Mid Louisiana) 60% share of

Mobil's gas from Block 140 for gas which Southern purchases from Ashland Oil,

Inc. ("Ashland") in Monroe Field, Louisiana.

Enbridge Pipelines (Midla), Inc. (formerly known as Mid Louisiana) will

deliver to the Grand Bay Exchange Point, through a new pipeline which Enbridge

Pipelines (Midla), Inc. (formerly known as Mid Louisiana) shall construct at

its sole cost and expense, that part of the gas produced from Block 140, which

it purchases from Mobil and will transport, without cost of Southern, the 40%

of the gas attributable to Mobil's interest in Block 140 gas which Southern

purchases.

Southern will accept delivery of Enbridge Pipelines (Midla), Inc.'s

(formerly known as Mid Louisiana) gas at the Grand Bay Exchange Point and will

have delivered to Enbridge Pipelines (Midla), Inc. (formerly known as Mid

Louisiana) Equivalent Volumes at the Cargas/Perryville Exchange Points.

Enbridge Pipelines (Midla), Inc. (formerly known as Mid Louisiana) shall

receive at the Cargas/Perryville Exchange Points all the gas Southern

purchases from Ashland in the Monroe Field in northeast Louisiana, regardless

of the occurrence of an event of force majeure (as specified in Article XII

hereof) which interrupts deliveries of gas by Enbridge Pipelines (Midla), Inc.

(formerly known as Mid Louisiana) to Southern at the Grand Bay Exchange Point.
