Leyton Orient came from behind to record a deserved win at former League One leaders Exeter thanks to Ruel Sotiriou's stoppage-time winner.
Orient started well, with Omar Beckles striking the crossbar inside the first seven minutes and then Sotiriou side-footed wide from six yards when an Exeter clearance fell right at his feet.
Idris El Mizouni forced Grecians keeper Gary Woods into a smart save as Exeter, missing several players through injury and international duty, failed to assert themselves.
However, the home side broke the deadlock in spectacular fashion in the 49th minute when 16-year-old debutant Jake Richards lobbed the ball forwards and Demi Mitchell allowed it to bounce before lashing a stunning 20-yard half volley over the head of Sol Bryan which went in off the underside of the crossbar.
Orient levelled six minutes later, though, as Joe Pigott was allowed to chest down a cross and fire a shot into the bottom corner from 10 yards.
Os defender Brandon Cooper forced Woods into a flying save with a shot from 20 yards, while Mitchell headed a good chance wide for Exeter.
But Orient won it two minutes into stoppage time when Sotiriou was afforded too much space 25 yards out and his low shot flew past Woods into the bottom corner.
