Greg Fisilau's last-minute try saw Exeter come from behind to beat Newcastle 17-15 to win the battle of the Premiership's bottom two sides.
Will Rigg's early try for the hosts was cancelled out soon after by the Falcons' Joe Davis before team-mate Max Clark put his side in front.
But with Newcastle's Richard Palframan yellow carded Martin Moloney drew the scores level, only for Brett Connon's penalty to put Newcastle 15-12 up at the interval.
Newcastle defended well as a scrappy second half produced few great scoring chances.
But in the final minute Exeter broke through the Falcons' stubborn defence as Fisilau went over in the corner.
The win was just a third of the season for Exeter as they closed the gap to eighth-placed Northampton to eight points.
The Falcons, who beat Exeter at Kingston Park earlier in the season, are now 10 points adrift at the bottom of the table.
Despite being against a strong wind it took Exeter just seven minutes to break through - Rigg dotting down in the right corner as Exeter moved the width of the field after strong pressure had seen them win a line-out penalty in the left corner.
But young scrum-half Davis drew the scores level five minutes later when he intercepted a loose Ben Coen pass and raced in under the posts from 25 metres for a try on his first Premiership start.
Fifteen minutes after Newcastle - who had not won away from home since November 2022 - went ahead when Clark forced his way over following eight phases from a five-metre line-out in the Falcons' first sustained period in the Exeter red zone.
Despite having the bulk of the first-half possession Exeter's attack struggled to create chances as the half wore on until Newcastle prop Palframan was sin-binned five minutes from half-time for an infringement in an Exeter line-out.
Two minutes later the Chiefs drew level as Moloney was forced over from a five-metre line-out before Connon kicked a long-range penalty on the stroke of half-time.
Exeter had half-chances to go ahead early in the second half, but each time they were thwarted either by their own errors or good defence from the visitors.
The Falcons - led by skipper Callum Chick - continued to defend well as the half wore on and almost went further ahead with nine minutes left but Connon's clever kick towards the left corner took a nasty bounce and evaded the onrushing Ben Stevenson.
But just as it looked as though Newcastle might hold on, Exeter struck.
Having laid siege in the Falcons' 22 Exeter lost the ball, but they regrouped in midfield and Kane James linked up with Harvey Skinner to break through before handing it on the Rusi Tuima and then Fisilau who went in - despite concerns there may have been a forward pass in the build up.
