In fallout new vegas, how can i get out of the camp after getting the chip, without dying. The legion hate me.?

i have boone along with me and we basically slaughtered legion all the way to the camp, ran inside without killing too many, and stole the chip. But now i cant get out without dying and my health is way to low to fight my way out. No more stimpaks either =/. So basically i need a way out of the camp peacefully but so that i wont have to fire boone. Ive also tried dressing up as legion but its too late for that now. Any suggestions?
