to correct the system problem for which the OFO

was issued, or 3) there is insufficient time to

carry out the procedures with respect to OFO's,

Company may periodically take unilateral action

be subject to a daily Failure to Comply OFO

Charge for each Dekatherm of gas by which it

deviated from the requirements of the OFO. The

daily Failure to Comply OFO Charge shall be

computed based on a price per Dekatherm equal to

reported for "Chicago city-gates" as published in

the Daily price survey in Platts Gas Daily for

the flow day on which the OFO is issued.

penalties if such charges or penalties

resulted from Shipper's compliance with

an OFO, including any preliminary action

taken by Shipper in response to an OFO

watch issued by Company as a precondition

to an OFO. Shipper shall not incur any

charges or penalties if Shipper was not

given reasonable time to comply with the

OFO.
