County, Arkansas, (the "36 Inch Crossing Facilities", jointly with the 18 Inch Crossing, the "Crossing Facilities"),

Southwestern will pay a daily demand rate surcharge of $0.05 per MMBtu (the "Facilities Surcharge") in order for

Texas Gas to recover commercially reasonable actual cost for pipe materials necessary for the 18" pipeline

installation and all labor, equipment, and materials necessary for new 36" horizontal directional drill,

installation (except for cost to purchase and pull the pipe), associated gas loss resulting from the decommissioning

from third parties for transportation or other services provided by Texas Gas if (a) such revenues are based upon the

payment of third parties of the Construction Costs of Texas Gas, whether derived from Facility Surcharges or other

charges that are similar in nature and intent of the Facility Surcharges or (b) such revenues are the result of any

increase in the rate level reflected in any agreements between such third parties and Texas Gas as of December 7,

2008. The Facilities Surcharge shall not be subject to adjustment under the most Favored Nations Provision of this

Agreement.
