9/ From February 6 to February 28, 2001, the combined reservation and commodity

transportation rate ("Rate") for the FTS-1 Agreement shall be calculated according to

the following formula:

The Gross Margin (defined below) booked by Shipper for all natural gas sold by

Shipper that was transported using capacity subject to the FTS-1 Agreement minus the

Fuel Value (calculated as the applicable volumetric percentage of fuel assessed under

Transwestern's FERC Gas Tariff times the applicable Gas Daily midpoint price for

receipts in the applicable receipt area; TW SJ (Blanco), for San Juan receipts, and

El Paso, Permian Basin Area, for East of Thoreau receipts) minus $0.50/MMBtu.

The Rate includes any and all applicable pipeline surcharges. In no event shall the

Rate be less that zero. Transwestern shall allocate the Rate between reservation and

commodity components inclusive of surcharges. Gross Margin shall be the difference

between the sales price per MMBtu to be received by Sempra and the commodity price

per MMBtu paid by Sempra for all gas sold by Sempra each day on the margin that was

transported using capacity subject to the FTS-1 Agreement.
