Dino Maamria's second goal of the game secured a hard-fought home win for Stevenage over Exeter which lifted them back into the play-off fight.
Anthony Elding struck his 10th of the season, heading home a Dannie Bulman cross, to give the home side the lead.
But Exeter's Steve Flack smacked in a 20-yard effort to level in time added on in the first half and netted again within 75 seconds to turn it around for the Grecians.
As Stevenage tried to shrug off that setback and regain the initiative, George Boyd stepped up. His free-kick found Maamria, who headed Stevenage level before producing a superb overhead kick to seal victory seven minutes from time.
Manager Graham Westley was pleased to see his side bounce back from the midweek home defeat by Woking:
"I think the important thing today was that we showed we had learned a lesson from the other night against Woking" he said.
"Having played some great football and having gone a goal behind we forgot we were a good side and we forgot the desire to go and win the game.
"But I think today the boys showed their character. They showed that if there is a collective desire in the camp the quality will come through and I think it did over 90."
