Stade Francais ran in five tries to dump Leeds out of the Challenge Cup.
Ceiron Thomas slotted an early penalty but the hosts hit back with two of their own from Lionel Beauxis.
Stade took advantage of Steve Thompson and Phil Nilsen being sin-binned and went 18-3 up at the break through Ollie Phillips and Hugo Southwell.
Rodrigo Roncero and Pierre Rabadan claimed two more tries for Stade, before Dan Browne hit back for Leeds - but Julien Arias' try sealed the win.
