12. BILLING AND PAYMENT (Continued)

12.4 Corrections. The time period for corrections to invoice or statement

data shall be six Months from the date of the initial invoice or

statement with a three-Month rebuttal period using the dispute

resolution procedures above, excluding government required rate

changes. This limitation does not apply in the case of deliberate

omission or misrepresentation or mutual mistake of fact. Parties'

other statutory or contractual rights shall not otherwise be

diminished by this limitation. If there is a deliberate omission or

misrepresentation of fact, there will be no time limit for

correction of the invoice. If there has been a mutual mistake of

fact, no corrections shall be made for an invoicing error unless

notice of the mistake is given within 24 Months after the mistake is

committed.

12.5 Adjustment of Overcharge and Undercharge - If it is determined

within the time limits specified in Section 12.4 that Shipper has

been overcharged or undercharged as a result of an error in billing

for which Transporter is solely responsible and Shipper paid such

bill, then the following procedures will apply. Unless mutually

agreed otherwise, Transporter shall refund within 30 Days of a final

determination the amount of any overcharge, with interest calculated

pursuant to Section 12.2(b) above. Unless mutually agreed

otherwise, Shipper shall pay within 30 Days of a final determination

the amount of any undercharge, with interest calculated pursuant to

Section 12.2(b) above. Interest shall be calculated from the time

such overcharge or undercharge was paid to the date of refund or

payment, respectively; provided, however, neither Transporter nor

Shipper shall be required to pay interest when such amount is less

than $100. This section does not apply to payments subject to a

billing dispute in accordance with Section 12.3.
