GENERAL TERMS AND CONDITIONS

Section 1

(Continued)

"Unauthorized Gas" shall mean gas received on any Day into Gulf

South's system (i) in excess of 110% of scheduled quantities in a

"Constrained Area"; or (ii) in excess of 120% of scheduled

quantities in a Non-Constrained Area and in total greater than

10,000 Dth for the Month; or (iii) without a scheduled quantity

and in total greater than 10,000 Dth for the Month. For purposes

of this definition "Constrained Area" is a portion of the

pipeline system evaluated for scheduling purposes where

nominations exceed capacity and where a posting has been made to

Gulf South's Internet Web Site identifying the area of constraint

and the time period anticipated for the area to be constrained.

The posting will be updated when constraint conditions warrant.

Gulf South will not determine gas receipts to be unauthorized

pursuant to (i) above on the calendar day the Constrained Area is

initially posted to the Internet Web Site.

"Virtual Point" refers to a nonphysical location established as

an aggregation point for all receipt points located within the

same rate zone. The rate zones are reflected on the map on

Tariff Sheet No. 11.

"Uniform Hourly Rate of Flow" shall mean the quantity of gas to

be received and delivered each hour. For purposes of this

Section, the term "Hour" shall mean each period of sixty (60)

consecutive minutes during a day beginning at 9:00 a.m., Central

Clock Time. The Uniform Hourly Rate of Flow shall be equal to

the scheduled nominations for the applicable nomination cycle

less the Elapsed-Prorated-Scheduled Quantity for the cycle

divided by the remaining hours in the day. Uniform Hourly Rate

of Flow does not apply to NNS Service unless the NNS Customer has

released the transportation portion of its No Notice Service or

has designated through a PDA that storage will not be used to

balance receipts and deliveries.
