GENERAL TERMS AND CONDITIONS

(Continued)

5. OPERATIONAL FLOW ORDERS (OFOs)

5.5 Situation Reports and Notices

(A) Southwest shall provide Shipper with as much advance notice

of OFOs as is reasonable under then existing conditions

through the Messenger system and the Web Site and by

telephone and by facsimile or via e-mail communication.

Each Shipper and point operator shall designate one or more

persons for Southwest to contact on operational matters on a

24-hour a day, 365 days a year basis. Telephone and

facsimile numbers as well as e-mail address must be provided

for such person or persons. If Southwest is unable to

contact any Shipper or point operator because that Shipper's

or point operator's contact person(s) is unavailable, such

Shipper or point operator shall be responsible for any

consequences arising from such failure of communications.

The notice will provide the time and date the OFO is to

become effective, the time the OFO is expected to remain in

effect, the action required of the Shipper, the reason for

issuing the OFO, together with operating variables providing

the basis for issuing the order, and any other information

which may be required in the circumstances. Ordinarily, the

notice will be issued by 10:00 a.m. CT on the Gas Day before

the OFO is to be effective. The OFO will ordinarily become

effective at 9:00 a.m. CT on the following Gas Day. When

operating conditions so require, three hours notice, or

lesser notice if necessary, may be given. An OFO may be

issued for a specific period of time or until further notice

is given. Such notice shall be provided to the person,

including any agent, designated by the Shipper to submit or

confirm nominations. Southwest will post notification and

provide updated information concerning the need for the OFO

on the Messenger system and the Web Site at the commencement

of the Gas Day until Southwest notifies the Shipper that the

order is no longer effective. Within a reasonable time after

the OFO terminates, Southwest will post on the Messenger

system and the Web Site a report detailing the conditions

that required the issuance and termination of the OFO.

(B) Southwest shall have no responsibility to inform Shipper's

end users, suppliers, other transporters or any others

involved in the transaction, as to any OFO.
