By signing below, I understand that I am authorizing Xanatek Inc to debit my checking account electronically for the appropriate amount as published in the current price list. If this amount is returned unpaid, I also understand that I am authorizing Xanatek Inc to re-debit this amount, as well as an additional debit $35.00, which is the return fee. This authorization is to remain in full force and effect until Xanatek has received written confirmation from the agency of its termination in such time and in such manner as to afford Xanatek a reasonable opportunity to act on it.
