Final Cut Pro X Export Help...

I have Final Cut Pro X 10.0.5 installed and I'm editing a video I made a while back; the RAW version I made was 700MB+ and the edited/exported version came out to 136MB (That I'm working on now) wants to be exorted as 441.4MB. I want to know how to get it exported as the same size it is now or smaller?? lol
