2. APPLICABILITY AND CHARACTER OF SERVICE (Cont'd)

(d) A Shipper may not exceed the sum of its MDQ at primary receipt

points on a given line segment as a result of pooling

transactions; provided, however, that a Shipper may also schedule

volumes from a pool or other receipt points on that line segment

as secondary receipt points or as AOS service, subject to

availability of capacity.

(e) The pools may not be listed as primary firm receipt or delivery

points under any service agreement.

3. POOLING NOMINATIONS AND SCHEDULING REQUIREMENTS

This section is applicable to all pooling transactions in addition to

the nomination and scheduling provisions set forth in Section 9 of the

General Terms and Conditions.

(a) Pooling Shipper of another Shipper must nominate a corresponding

quantity of gas from a production area pool to a Production Area

transportation agreement for delivery to any delivery point

otherwise accessible under such transportation agreement or to the

Market Area Pool. Pooling Shipper or another Shipper must

nominate a corresponding quantity of gas from the Market Area Pool

to a Market Area transportation agreement for delivery to any

delivery point otherwise accessible under such transportation

agreement. Nominations from one Pooling Shipper to another within

the same pool are also permitted, provided however, such

nominations remain subject to Section 2(b) above. Nominations

from a Pooling Shipper's Pooling Service Agreement to the same

Pooling Shipper's PLS Service Agreement within the same pool are

also permitted.

(b) Pooling Shipper or another Shipper must provide priority ranking

for gas delivered to or received from a pool. If ranking is not

provided, pro rata will be used. If either the delivery volume or

receipt volume confirmation is less than the nomination, Southern

Star will follow the "lesser of" rule (both sides of the

transaction will be adjusted to correspond to the "lesser of"

volume). The priority ranking for gas delivered to a PLS service

agreement will default to interruptible.
