Will activating at end of trial period license 3 machines?

I am running a 30 day trial of NIS 2010.  Next week my trial term ends.   I have purchased a retail NIS2010 which allows installation on 3 machines.

 

I assume

 

1) that I can use this retail license on the trial version of NIS2010 to activate it fully before the trial expires without having to uninstall/reinstall NIS 2010

 

2) activating before the end of the trial with the retail license will now all my product to be installed on 3 machines instead of just one (the trail limit). 

 

Is this correct?
