Old term and new term subscription question

Hi, Matthew, a question for you. If you can give some help, I will

greatly appreciate. If I subscribe to a system with trial period. After I

subscribe, the system owner changes the term. How will this affect my

subscription. Let’s give a detailed example. If I subscibed a system on

06/01/2006, the system has 14 days free trial, then charge $10 for a month.

On 06/05/2006, the system owner changes the term to 5 days free trial, then

charge $100 for a month. Which of the following billing schedule will be?



A. subscribed date 06/01/2006, charge $10 on 6/15/2006, then charge $100 on

7/15/2006.



B. subscribed date 06/01/2006, charge $100 on 6/6/2006, then charge $100 on

7/6/2006.



If the old term charge is 0, then what charge schedule will be?



C. subscribed date 06/01/2006, charge 0 on 6/15/2006, then charge $100 on

7/15/2006.



D. subscribed date 06/01/2006, charge $100 on 6/6/2006, then charge $100 on

7/6/2006.



Thanks.
