Fuel Reimbursement volumes. Shipper shall also receive or cause to be received gas requested to be

shall receive gas for injection from Shipper at the Point(s) of Receipt located on its system and

deliver gas to Shipper at the Point(s) of Delivery located on its system as scheduled by Shipper

from time to time; provided that PetroLogistics shall not be obligated to receive for injection any

quantity of gas if the injection of the same would cause the quantity of gas stored for Shipper's

gas to Shipper than Shipper has stored in its Storage Inventory, Park Balance and/or Loan Balance,

as applicable.

obligated to receive, at any Point of Receipt for injection, or deliver, at any Point of Delivery,

PetroLogistics at any such Point of Receipt or requested for delivery at such Point of Delivery,

results in a net metered flow which is less than or equal to 5,000 Dth per Day.

4.4 In the event that batch flowing nominated volumes of less than 5,000 Dth per Day is deemed

operationally impractical by Transporter or PetroLogistics, and should PetroLogistics 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

Dth per Day, PetroLogistics will attempt, but shall not be required, to schedule such nominations.

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 Dth per Day, all nominations may

be curtailed on a pro rata basis such that the net metered volume will be zero. PetroLogistics will

verbally notify the affected Shipper(s) within four (4) hours of being notified of changes to

nominations which would result in curtailment as provided herein.
