Montpellier became the fourth French club to top their group by beating Exeter Chiefs 32-30 on Saturday.
A late Quentin Doumayrou try saw Montpol break Exeter hearts and reach the quarter-finals.
Exeter had led 30-25 after tries from Luke Arscott and Matt Jess (two) plus 15 points from the boot of Ryan Davis.
Montpellier's Raphael Legarde kicked six penalties and converted a try from Goderzi Shvelidze, before Doumayrou struck and Legarde added the extras to dump the Chiefs out of Europe.
