Mass Effect Edit
The Normandy catches up with the Ontario before she can reach the asteroid belt, and Commander Shepard leads a rescue party inside. Burns is being held at gunpoint in the back of the freighter, begging for his life and claiming that he's changed his mind. The L2s are prepared to execute Burns anyway, saying he's had his chance already and blew it.
If pushed, the L2s will kill Chairman Burns before being killed themselves by the squad. Alternatively, Shepard can try to make the case that the L2s need Chairman Burns alive to make any real changes. If he survives, Burns claims he had no idea that the L2s were so desperate, and vows that the reparations will come.
Mass Effect 2 Edit
If Chairman Burns was rescued, he stays true to his word: L2 biotics have received reparations for their implants. In the news report covering the event, Burns thanks biotics everywhere and promises more help for people who have been "forgotten by the system". He also sends Commander Shepard a message, entitled "Thank you again."
