GENERAL TERMS AND CONDITIONS

(Continued)

41.4 (Continued)

Notwithstanding the above, in the event that the COMPANY

has in effect such limitation notice and the actual overall

system imbalance is opposite to the direction of the said

notice, SHIPPER shall not be penalized.

(b) Insofar as practicable, when COMPANY detects the

development of a system imbalance that threatens the

physical or operational integrity of its pipeline system as

described in 41.4(a) above, COMPANY shall endeavor to

identify those SHIPPERS making a significant contribution

to the imbalance and to contact such SHIPPERS in an effort

to reduce the system imbalance and avoid the necessity of

imposing penalties as set forth in 41.4(a)above. It is

recognized, however, that such prior notification may not

be possible under all circumstances, e.g., when COMPANY

must act quickly in order to protect the integrity of its

system.

(c) Based on an evaluation of current and forecasted system

conditions, COMPANY shall post by 2:00 p.m. (CCT) each

Friday, or, if Thursday or Friday is a recognized COMPANY

holiday, then on the day before such recognized COMPANY

holiday, the probability of implementing an OFO under this

Section 41.4 for the succeeding Saturday, Sunday, and

Monday and the Thursday and/or Friday during a recognized

COMPANY holiday. If system conditions change, COMPANY

shall update such posting periodically throughout the

weekend.
