Truecrypt installs and runs but is unable to use the Unity system tray for the program running in the background. If one exits the main program can not be restarted to unmount the encrypted volume(s). I have tried white-listing 'truecrypt' but it still does not allow the background program to appear in the system tray.

You need to create a mount point in order to do what you want.
If I want my truecrypt1 volume to show up as "Private", I'll create a "Private" mountpoint with sudo mkdir /media/Private
Then launch Truecrypt, select my encrypted drive and when I click on "Mount" I'm asked for my password and I can click "Option" to select my custom mount point.
Voilà, it's done.
ALLTRAY 
AllTray is a program written for Unix-like systems to enable a user to dock any program (such as Evolution, Thunderbird, or a terminal program) into the system tray. This is mostly useful when one wants to have a program always running, but easy to put out of the way.
with AllTray, you can minimize any app to the system tray.

Whitelist 'Truecrypt' instead, log out, log in again and it should show up:
