as applicable, multiplied by the monthly imbalance, plus

(3) an additional amount to cover Company's cost of gas for the system fuel and

use and lost and unaccounted for gas.

The additional amount shall be calculated by multiplying the Index Price by the

amount of fuel necessary to transport the imbalance on the systems of both

The Index Price shall be posted on the System. The Index price shall be

calculated by using Natural Gas Week's "Gas Price Report." The Index Price shall

be a weighted average price based upon the general system deliverability on

Tennessee's system (such system deliverability being updated semi-annually) from

four Receipt Regions and the applicable Region Prices for such Receipt Regions

(the Receipt Regions are Texas Offshore, Texas Onshore, Louisiana Offshore, and

Louisiana Onshore). The Index Price will be posted on the System in a reasonable

time after receipt of Natural Gas Week's "Gas Price Report." The applicable

general system deliverability will also be posted on the System. If Natural Gas

Week's "Gas Price Report" is no longer published, Company shall use the

alternative spot price indices agreed to be used under Tennessee's Rate

Schedule LMS-MA. Company shall allocate "cash-outs" with other upstream

pipelines according to the same formula.
