Irish province retain hopes of winning Europe’s premier club competition.
Leinster overcame Exeter 29-20 to keep alive their slender hopes in the Heineken Cup.
The Irish province, who have won the competition twice before, now need to wait or other results to see if they are to remain in the tournament.
Leinster finished second in Pool 5 behind runaway leaders Clermont and can only make the quarter-finals by claiming the remaining best runners-up spot after Montpellier booked their last-eight place earlier in the day.
The Irishmen had trailed Exeter 17-12 at the interval after converted tries from Neil Clark and a penalty try helped edge the visitors’ scores from Gordon D’Arcy and Rob Kearney.
Brian O’Driscoll then brought Leinster level before Jamie Heaslip’s try earned a bonus point victory.
Leinster finished their group campaign with 20 points, but Irish rivals Munster can deny them a quarter-final spot if they score four tries and beat Racing Metro on Sunday in Pool 1 where Saracens are also expected to qualify by beating Edinburgh.
Clermont had already made sure of their quarter-final place and Saturday’s 29-0 win over the Scarlets gave them 28 points from six wins and a home clash in the next round against Montpellier.
Montpellier defeated Toulon 23-3 in an emotionally-draining clash to reach the quarter-finals for the first time.
Montpellier, playing just days after the death of forwards coach Eric Bechu, finished their Pool 6 campaign on 22 points, enough to take one of the two best runners-up spots.
Despite the defeat, Toulon had already made the last eight as pool winners.
