RATE SCHEDULE SGT (cont'd)

11.3 Maximum Daily Injection Quantity:

To protect the storage formations and allow uniform filling of the storage

reservoirs, Customer will be required to adhere to certain injection limits

(calculated as a percentage of the Unnominated Seasonal Quantity), throughout

the summer injection period. During the Summer Season Customer may, on a daily

basis, inject according to the following table:

% of Unnominated Maximum Available

Seasonal Quantity Injection Rate

Injected (% of USQ)

0% - 65% 1.3%

65% - 90% 1.1%

>90% 0.6%

11.4 Inventory verification tests will be conducted on a semiannual basis. These

tests require the temporary suspension of individual storage field activities

(injections and withdrawals) for a period of approximately two (2) weeks. If

conditions will not permit the full maximum daily injection or withdrawal

quantity, Texas Gas may temporarily adjust the limit and allow make-up

quantities on succeeding days. Texas Gas will provide at least 45 days notice

on its Internet Website in regard to the scheduling of these shut-in periods to

allow Customers to adjust for the interruption of storage.

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

requirements. 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 Summer 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.
