Player 2 : You need to get a portal on the slanted wall near player 1 (it just up and to the right of where their light bridge will be), and a second portal down below you on the single panel here.
Player 1 : Run across the light bridge until you're directly over the portal that's underneath you. Once you're sure you're ready, turn around to face player 2 and fire off a portal into the wall located up and to your right. This'll cause you to fall into the portal and out through the slanted one, right to the exit!
