Can I disable expose from displaying an app?

I am required to use a VPN client to access the internet at my campus. The application I use cannot be exited and therefore I just minimize to the dock and hide it. Though, when I activate expose it shows up due to snow leopard which allows minimized windows to be displayed in expose now.

So, my question is; is there a way to disable this specific VPN app from displaying in expose at all?
Scripts?
Other apps?

any help is appreciated! thanks

 

Wow! Haha, that was very simple and worked!
Thank you very much
