Sireli Naqelevuki scored for the second week in succession for the Chiefs
Exeter continued their perfect start to the new Premiership season with a bonus-point win over Newcastle.
The hosts started with the same vigour as last week when Josh Tatupu went in for a try inside a minute before Ignacio Mieres kicked five points.
Tom Catterick got the Falcons' first try of the season before half-time.
Sireli Naqelevuki and Phil Dollman's tries put Exeter in charge before James Fitzpatrick's late reply and Jason Shoemark's even later bonus-point try.
Tatupu came off his right wing to hit the midfield for his opener as the Chiefs repeated the explosive start they gave at Welford Road last weekend.
Mieres added the simple conversion and then a 45m penalty after the hosts held out several promising Newcastle attacks.
Catterick broke through on 25 minutes when he squeezed into the left corner but his try went unconverted, and after Dollman's line break 10 minutes later Mieres landed another three points from the tee.
An infringement at the ruck gave Jimmy Gopperth a shot at goal, which he scored, on the stroke of half-time.
Naqelevuki barged through and scored under the posts after the restart but Newcastle did not lie down and exerted pressure on the hosts' defence but even a series of close-in scrums proved fruitless.
Matt Jess broke from deep with five minutes remaining before feeding inside to Dollman, who went in under the posts.
Fitzpatrick took advantage of some loose defending as Exeter looked to grab a bonus point and Gopperth added the extras but it was little more than a consolation.
Chiefs secured their bonus point through centre Shoemark at the death when he squeezed into the corner.
Exeter head coach Rob Baxter told BBC Radio Devon:
"A little bit of ball retention let us down at times but nothing too major.
"There have been a few things we're still looking to introduce into our game and we'll get there over the next few weeks.
"You can't assume that playing in front of your home crowd will be enough to win you a game of rugby."
Newcastle head coach Alan Tait:
"You work at a problem all week to sort things in defence but then we let them score from the very first play - almost as we did with Bath last week.
"But after that we played the best 38 minutes I have seen our lads play for a long time and get ourselves back in the game. In the second half I thought that we would kick on but Exeter have power runners.
"One individual like their man of the match Sireli Naqelevuki can just break down defences and get over the try line can give you a bit of breathing space.
"There were key times when we could have got back into the game but we didn't get it right.
"That is where we will have to sit down in the coming week and sort these things."
