GENERAL TERMS AND CONDITIONS (Continued)

5.4 In the event that batch flowing nominated volumes less than 5,000 MMBtu

per day is deemed operationally impractical by Interconnecting Pipeline

or Petal, and should Petal receive nominations for the injection or

withdrawal of gas, which after aggregation with other nominations

commencing at the same time and same meter, results in a net metered

volume less than or equal to 5,000 MMBtu per day, Petal will attempt to

schedule such nominations on a "best efforts" basis. However, if any

single or combination of nominations is scheduled such that the

aggregated nominated volumes result in a net metered volume less than or

equal to 5,000 MMBtu per day, all nominations may be curtailed on a

pro-rata basis such that the net metered volume will be zero. Petal will

verbally notify the affected Customer(s) within four (4) hours of being

notified of changes to nominations which would result in curtailment as

provided herein.
