Crewe Alexandra missed out on top spot after being held to a 0-0 draw at promotion rivals Forest Green last night.
Manager Dave Artell made two changes going into the game.
Eddie Nolan and Paul Green came in for Christian Mbulu and Oli Finney.
In a tight affair, Ryan Wintle shaved the post and Chris Porter also came close to breaking the deadlock.
But the Alex had to settle for a share of the spoils.
Forest Green remain second with Crewe third, two points behind leaders Swindon.
Speaking to the club's official website manager Dave Artell said: "We deserved the clean-sheet and if there was any team going to win it then it was us. I think it was a good advert for League Two and we probably shaded it with the two good chances we had.
“Chris has chipped the goalkeeper in the first half and it has just gone wide and he then got a slight touch onto Ryan’s (Wintle) shot and it hit the inside of the post.
“It was a terrific point for us against a good side. I would say they are they are probably the best side we have played this season over 90 minutes. Exeter were very good in the 45 minutes when we played them but we were very good in the second half.
“They set-up to let us have the ball and tried to hit us more on the counter-attack but I think we restricted their genuine chances. Mark (Cooper) would have looked at us and been wary of our attacking threat and they set-up to stop us and they will say that it worked because we haven’t scored.
“On other night, we may have scored one or both of the chances we had and then that would have been an even better result – but I cannot fault our lads. They put a real shift in against the team that are second and going well. We have come here and probably shaded it overall and I’m pleased with the performance."
Crewe are back in action on Saturday when they make the trip to Eastleigh in the second round of the FA Cup.
