8.4 Correction of Billing Errors - In the event an

adjusted within three (3) months of the claim

therefore, provided that claim therefore shall

have been made within six (6) months from the

date of the intial transportation invoice and 7 months

from the date of intial sales invoice, excluding

government-required rate changes. This standard will

not apply in the case of deliberate omission or

misrepresentation or mutual mistakes of fact.

Shipper shall provide notice to Western of such

disagreement by providing detailed calculations

supporting the disputed amount and the basis for the

dispute and the amount paid on or before the

the bill is due. If an invoice is in dispute,

Buyer or Shipper must pay the portion not in dispute.
