13. ALLOCATION AND IMBALANCES (cont'd)

(a) Clearing of negative imbalances. Should such imbalance be

negative, the imbalance shall be subject to Negative Imbalance

Cash-Out.

The Negative Imbalance Cash-Out Price is a price per Dth

which is applied to the amount of the Shipper's negative imba-

lance. Shipper's regular invoice for transportation services

will include the money owed by Shipper under this Negative

Imbalance Cash-Out, which will be subject to all payment and

collection requirements applicable to that bill. Upon receipt of

payment, Transporter will make gas accounting entries reducing

the amount of Shipper's negative imbalance accordingly.

Transporter shall post the Negative Imbalance Cash-Out Price

for each month on its Web Site. The Negative Imbalance Cash-Out

Price shall be equal to one hundred ten percent (110%) of the sum

of SWI + WAT (the "Index"), where:

SWI = Southwest Index, which is the arithmetic average of all

spot gas index prices per Dth reflective of the first

day of the month quoted by: (i) Natural Gas Intelli-

gence "Spot Gas Prices," "Delivered to Pipelines," "30-

Day Supply Transactions," and (ii) Inside FERC "Gas

Market Report," for deliveries of gas produced in Texas

and Louisiana into the system of Columbia Gulf Trans-

mission Corporation ("Columbia Gulf") and Columbia Gas
