Williams was part of an ugly brawl which broke out on the sideline during the 77th minute at Sandy Park.
He had earlier been substituted following a head injury, but dashed from the technical area to join in the fracas, which was sparked after Duncan Taylor had clashed with Exeter scrum-half Nic White.
Once tempers had calmed down and order had been restored, Williams was shown a red card by referee Wayne Barnes, who declared his behaviour "not acceptable".
Williams appeared before an independent disciplinary panel on Thursday, where he accepted the charge which was "for acts contrary to good sportsmanship, contrary to World Rugby Law 9.27".
Chair Richard Whittam QC, the sole independent judicial officer, handed out a two-week ban, which will see Williams free to play again on January 14.
Williams will now miss the Premiership match at London Irish as well as the European Champions Cup fixture at Glasgow Warriors.
