Overcharged Amounts. If based upon Manifest Error Off-Taker reasonably believes that any invoice incorporates overcharged amounts in respect of amounts properly payable under this Agreement, then Off-Taker shall notify Provider in Writing of such overcharge, including the amount and the basis of such Manifest Error within a reasonable time.
