You're starting in an office with rows of chairs off to your right. Go through the brown door at the end of the room in front of you. You'll exit to the left. Take a step out into the hallway by the fire extinguisher. Turn left and walk all the way down this hallway. You'll keep the glass wall on your left. Walk through the door that has the exit sign above it. You'll see a white pillar once you cross that doorway. The white pillar is in an empty room. Take a step toward that pillar. You are done.
