RATE SCHEDULE SGT (cont'd)

Customer's Unnominated Seasonal Quantity shall be withdrawn by April 1 (the end of

the Winter Season).

10.6 Adjusted Unnominated Daily Quantity: As Customer's Unnominated Seasonal Quantity

is withdrawn, that portion of Customer's Unnominated Daily Quantity available to

Customer shall be adjusted. Customer's Adjusted Unnominated Daily Quantity shall

be equal to the greater of its average winter daily unnominated quantity (i.e.,

the Customer's USQ divided by the total number of Winter days the UDQ is

available) or the applicable percentage of its Unnominated Daily Quantity as set

forth in the following table:

% USQ Withdrawn % UDQ Available

75% 90%

80% 85%

85% 80%

90% 75%

10.7 During the Winter Season, Texas Gas will also inject gas into storage on a best

efforts basis as part of SGT service. Although such injections will be done on a

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

contrary, to be able to inject into storage such quantities of gas as to take into

account routine variations in no-notice deliveries. If Texas Gas is unable to

make such best efforts injections, it will advise Customer by posting on its

Internet Website. However, no presumption will exist for non-routine situations

(e.g. injections in excess of 15% of Customer's Winter Contract Demand or

sustained injections 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 inject into storage, so that Texas Gas can determine the extent to

which it can make such injections and adjust its operations accordingly.

11. Summer Season Provisions

11.1 Texas Gas shall be obligated to deliver to Customer at the city-gate during each

Summer Season up to the Customer's Summer Contract Demand and Adjusted Summer

Quantity Entitlement.

11.2 Pursuant to the provisions set forth below, Customer shall deliver in kind to

Texas Gas during each Summer Season a quantity of gas equal to that portion of

Customer's Unnominated Seasonal Quantity actually utilized by Customer during the

prior Winter Season (as well as any Shoulder Month quantities delivered to

customer during the Summer Season). Customer shall reserve and utilize such

portion of its Summer Contract Demand as necessary to redeliver such volumes into

storage.
