Oyonnax have signed Exeter winger Fetu'u Vainikolo on a two-year deal as they look to build on a promising Top 14 campaign.
On course for the play-offs for the first time in their history, Oyonnax have been active on the transfer market, with Piri Weepu and George Robson among those on their way next season.
They will be joined by fellow Premiership player Vainikolo, who will join after two seasons with Exeter, signing a two-year deal with the club.
The 30-year-old Tongan international made his name in Super Rugby with the Highlanders before heading to Europe to play for Connacht.
He played 37 games in two seasons with the Irish side, before playing a further 29 games for Exeter.
