GENERAL TERMS AND CONDITIONS (Continued)

(b) Except for force majeure events and/or events or conditions which threaten the integrity of

Transporter's system or Transporter's ability to meet its firm service obligations, Transporter will notify

Shippers at least 24 hours in advance on its Internet EBB (1) the effective dates of the Critical Day; (2)

the type of penalties that will be applicable during the Critical Day period; and (3) to the extent

applicable, the Market Areas where penalties will be applied. If due to declaration of a Critical Day, a

monthly penalty becomes applicable, Transporter will notify Shippers by posting on its Internet EBB notice

that the monthly penalty is applicable. Within two weeks of a Critical Day event, Transporter will post

information on its EBB describing the events leading up to the declaration of the Critical Day.

(c) Transporter anticipates that Critical Day penalties will be implemented to impose system

discipline to ensure Transporter’s ability to meet its firm service obligations. To the extent Critical Day

penalties are no longer imposing system discipline, such that Transporter’s firm service obligations are

being threatened, Transporter can implement an OFO to alleviate conditions threatening the integrity of

Transporter’s system. Transporter can also implement an OFO to deal with sudden, unexpected and

catastrophic events on its system.

(d) When reasonably feasible, Transporter will post notices on its EBB advising that if Shippers

take certain specific actions, Transporter may be able to avoid the issuance of a Critical Day, or minimize

the sequential issuance of Critical Days.
