Tommy Seymour gave Glasgow the perfect start

Glasgow's four tries gives them a bonus point to add to the two points for the draw. Warriors travel to Sale Sharks next weekend knowing they need a bonus-point win and some favours from other teams to reach the play-offs. The result sees Exeter secure top spot in the pool.

Warriors were left to rue yellow cards in each half, to Callum Gibbins and Fraser Brown, and two huge chances for Huw Jones which went begging in the opening five minutes of the second half.

They move on to 12 points ahead of their final game at Sale next weekend and have slim hopes of reaching the last eight as one of the three best runners-up.

The teams were level at the midway stage after Exeter bounced back from conceding two tries from Tommy Seymour and Huw Jones inside the opening eight minutes. George Horne added a third try. Exeter pushed themselves ahead and Warriors were ultimately grateful for Nikola Matawalu's try and a brilliant conversion from Adam Hastings to level the scores - although they thought they had won it before Sam Johnson had a try disallowed for a forward pass.

Stuart Hogg could have stolen full points for Exeter but his penalty from his team's own 10 metre line hit the bar.

"We just couldn't get the ball to sit up," Dave Rennie told BBC Scotland after the match.

"I think we had four clear opportunities if it had sat up. We created a lot of opportunities. We're proud of the effort, frustrated as well.

"We made some pretty good decisions but in the end didn't get the result."

A loss away to Exeter in November and a damaging home defeat to La Rochelle meant Rennie's side needed to close with two bonus-point victories to claim a best runners-up spot.

Exeter, unbeaten in the group, made the most of Glasgow's yellow cards, scoring 21 points during those periods.

Rennie thought Gibbins was unfortunate to be penalised for leading with his shoulder in a clearout, but had no complaints on Brown's departure which came as the English Premiership leaders laid siege to the try-line.

"I didn't see much in that to be honest, I thought they were looking at one of their guys," he said of the first offence. "I could tell by Callum's reaction he was pretty miffed about that.

"Fraz I can understand. He (the referee) said there were four penalties in a row while they're in possession so fair enough for that."

Home supporters were celebrating when Johnson slid over late in the game but officials spotted a forward pass from Adam Hastings in the build-up.

"I guess with our game pretty much anything we throw with a bit of distance goes forward," said Rennie. "It certainly travelled forward. I've seen worse given, but not tonight.

"We played a lot of good footy and it highlights what we're capable of. We let in a couple of soft tries and if they pin you under the posts they're going to keep asking questions, you've got to give them credit."
