GENERAL TERMS AND CONDITIONS

5. BILLING AND PAYMENT (Continued)

5.4 Failure to Pay Bills. Should Shipper fail to pay all of the amount

of any bill, when the same becomes due, Transporter shall have the right

to charge Shipper a late charge on the unpaid balance which shall accrue

on each calendar day from the due date at the rate specified in Section

154.501(d) of the Commission's regulations. If such failure to pay

continues for thirty (30) days after payment is due, Transporter, in

addition to any other remedy it may have under the Service Agreement,

may; (1) discontinue transportation service for self-implementing

transactions without Commission approval, or (2) after application to

and authorization by the Commission suspend further service until such

amount is paid. However, if Shipper in good faith shall dispute the

amount of any such bill or part thereof and shall pay to Transporter

such amounts as it concedes to be correct, then Transporter shall not be

entitled to suspend further service.

5.5 Right to Set Off Unpaid Amounts. In the event that Shipper does

not pay the full amount due in accordance with Section 5.3 hereof,

without prejudice to any other rights or remedies it may have,

Transporter shall have the right to withhold and set off payment of any

amounts of monies due by Transporter to Shipper, whether in connection

with the Service Agreement in dispute or otherwise, against any and all

amounts or monies due or owing by Shipper to Transporter for services

performed under the Service Agreement in dispute.
