GENERAL TERMS AND CONDITIONS

(continued)

For imbalances due Imbalance Party, the Purchase

Posted Price shall equal the lowest of the simple

arithmetic averages, as determined below, of the daily

midpoint spot prices for gas delivered to Transporter

at Florida Gas zone 1, Florida Gas zone 2 or Florida

Gas zone 3 as reported in Gas Daily. The simple

arithmetic average for each index for each month shall

be determined by adding the daily midpoint prices for

the flow dates beginning with the sixth calendar day

of the month in which the imbalances occur through the

fifth calendar day of the month following and dividing

the sum by the number of days. In the event that

these prices are no longer available or the basis upon

which such price is reported or calculated in such

publication changes substantively, Transporter will

file to change its tariff and may, at its discretion,

select representative price in the interim period,

subject to Commission approval.

(b) The amount due Imbalance Party shall be the imbalance

quantity multiplied by the product of the

corresponding imbalance level factor multiplied by the

Purchase Posted Price for the month.

3. Aggregating of Imbalances of Imbalance Party

To the extent Imbalance Party has multiple Receipt, NNTS or

Delivery Imbalances, Transporter shall resolve imbalances

with the Imbalance Party as follows:

(a) NNTS Imbalances first shall be netted against Delivery

Imbalances to determine the final Delivery or NNTS

Imbalances subject to cash out; and
