RATE SCHEDULE SGL (cont'd)

11.5 During the Summer Season, in addition to the nominated Daily Quantity actually

scheduled by Customer, Texas Gas will adjust deliveries from storage up to

Customer's Unnominated Summer Daily Quantity to meet Customer's city-gate

requirement. Notwithstanding the previous sentence, during the Summer Season

(except as provided in Section 11.4 above), Texas Gas will also, on a best

efforts basis only, withdraw gas from storage (i) in excess of Customer's

Unnominated Daily Quantity, or (ii) if Customer's SGT Service Agreement does not

include an Unnominated Summer Daily Quantity, in excess of Customer's Nominated

Daily Quantity; however, total deliveries to the Customer may not exceed the

Summer Contract Demand. Although such withdrawals will be done on a best efforts

basis, Texas Gas will be presumed, unless it gives notice to the contrary, to be

able to withdraw from storage such quantities of gas as to take into account

routine variations in no-notice services. If Texas Gas is unable to make such

best efforts withdrawals, it will advise Customer by posting on its Internet

Website. However, no presumption will exist for non-routine situations (e.g.

withdrawals in excess of 10% of Customer's Winter Contract Demand or sustained

withdrawals of more than five days) and, in such non-routine situations, Customer

must give 24 hours advance written notice to Texas Gas of quantities it desires

to withdraw from storage, so that Texas Gas can determine the extent to which it

can make such withdrawals and adjust its operations accordingly.

11.6 To assist Texas Gas' operational and maintenance scheduling through the Summer

Season, Customer will notify Texas Gas by March 15 of each year, with updates

monthly, of the quantities it intends to inject monthly during the immediately

upcoming Summer Season; such injection schedule provided by Customer is a best

efforts estimate and may be revised as necessary. Texas Gas will use its

reasonable efforts to coordinate its test, maintenance, alteration and repair

activities during such Summer Season to accommodate Customer's request.

12. Shoulder Month Flexibility

12.1 During the Shoulder Months of April and October, Texas Gas will deliver to

Customer at the city-gate the Customer's Shoulder Month Contract Demand, which

shall, unless otherwise agreed, be the sum of Customer's Nominated Daily

Quantity, Customer's Excess Unnominated Quantity and the applicable percentage as

set forth below of Customer's Unnominated Daily Quantity for the Winter Season:

Shoulder Month Percent of Unnominated Daily Quantity

April 50%

October 70%
