GENERAL TERMS AND CONDITIONS

10.4 Shipper shall pay Transporter, at its general

office, or at such other address as Transporter shall

designate, the amount due for the preceding month

within ten days after receipt by Shipper of the bill

from Transporter.

10.5 Should Shipper fail to pay all of the amount of

any bill when such amount is due, Transporter shall

collect interest on the unpaid portion of the bill in

the manner and at the rate prescribed by 18 C.F.R.

154.67(c). If such failure to pay continues for 30

days after payment is due, Transporter, in addition to

any other remedy it may have, after giving Shipper 15

days' written notice, may suspend further receipt

and/or delivery of gas for Shipper until such amount is

paid. If Shipper in good faith shall dispute the

amount of any such bill, Shipper shall nevertheless pay

to Transporter the amount of such bill and, at any time

thereafter within 30 days of a demand made by Shipper,

Transporter shall furnish a good and sufficient surety

bond guaranteeing refund to Shipper upon such bills after

a final determination by agreement, by determination of

regulatory agencies having jurisdiction, or by judgment

of the courts, as may be the case.

10.6 If it is determined that Shipper has been

overcharged, and Shipper has paid the statement

containing the overcharge then, within 30 days after

the final determination, Transporter shall refund the

amount overcharged with interest in accordance with

10.5. If it is determined that Shipper has been

undercharged, Shipper shall pay the amount undercharged

with appropriate interest within 30 days of notice by

Transporter of the amount. Provided, however, no

adjustment will be made to any statement more than 24

months from the date of such statement unless disputed

within that period. In the event that any portion

of a statement is in dispute, payment of the disputed

portion shall not be deemed a waiver of the right to

contest such disputed portion in any forum having

jurisdiction.
