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-PA. Company shall allocate "cash-outs" with other upstream

pipelines according to the same formula.


For the purpose of determining the level at which a Balancing Party's imbalance

shall be cashed out, if a Balancing Party has an imbalance outside a given

tolerance level, the escalating or declining percentage of the Index Price will

apply only to the portion of the imbalance outside of the tolerance level.


The amounts due hereunder shall be paid in accordance with Sections 5 and 6 of

the General Terms and Conditions of Company's FERC Gas Tariff.


(c) Access to Information


Company will make available by electronic means the best information it has

concerning the scheduled deliveries at all Delivery Points. This information

regarding the scheduled deliveries shall become "Operational Data" and Balancing

Parties will be able to utilize the Operational Data for purposes of correcting

imbalances during the month. Monthly imbalances will be cashed out on the basis of

actual deliveries and Scheduled Quantities; provided that the penalty level and

pricing associated with imbalances will be based upon the lesser of (1) the monthly

operational imbalance reported by Company based upon the Operational Data or

(2) the monthly imbalance based upon actual receipts and deliveries at such
