I agree that I will be charged for the amount listed in the upper right-hand box for the number TATEMS PC computers I want to use TATEMS on. The initial charge is for 1 month of TATEMS use and this includes version upgrades and support. Then in 1 month I will be charged for the ongoing subscription for use of TATEMS which also includes ongoing version upgrades and support. I understand I can cancel the monthly subscription at any time and will loose ability to use the TATEMS software after at the end of the currently paid up month.
