GENERAL TERMS AND CONDITIONS

----------------------------

23.7 CRITICAL TIME

(a) Natural shall advise Shippers on its system if it

is declaring a Critical Time, as described in Section 12.5 of these

General Terms and Conditions, and shall specify the nature of the

situation creating the Critical Time.

(b) Natural may issue Operational Flow Orders as

described in Section 23.6 during a Critical Time. Natural will waive

(i) injection storage charges under Rate Schedules DSS and NSS for

Shippers that provide extra gas to the system during a Critical Time

when there is a need for more gas, and (ii) withdrawal storage

charges under Rate Schedules DSS and NSS for Shippers that increase

takes from the system during a Critical Time when there is a need to

reduce the amount of gas on the system.

(c) The penalty for failure to abide by an Operational

Flow Order issued during a Critical Time shall be equal to the

volume (in Dth) by which Shipper deviated from the requirement of

the Operational Flow Order multiplied by the greater of (i) $15.00

or (ii) the sum of three hundred percent (300%) of the highest

authorized overrun rate which can be applicable to an FTS Agreement

on Natural's system pursuant to Section 12 of these General Terms

and Conditions plus three hundred percent (300%) of the highest

Weekly Index Price used to determine the Average Monthly Index Price

(as determined in accordance with Section 13) for the month in which

the violation occurred. Additional amounts may be billed pursuant to

Section 23.10.

23.8 UNILATERAL ACTION

In the event that the actions under Sections 23.4

through 23.7 are inadequate or there is insufficient time to carry

out such procedures, Natural may periodically have to take

unilateral action to maintain system pressure and preserve the

overall operational integrity of Natural's system (or any portion

thereof). Natural is authorized to use all the resources of its

system to such ends, through the integrated operation of storage,

line pack, and supply received into Natural's system, even though

gas may be owned by a person other than the entity receiving

delivery. Natural shall not, however, be responsible as a supplier

of gas to any Shipper.
